MARSHALL, C.J.

Marriage is a vital social institution. The exclusive commitment of two individuals to each other nurtures love and mutual support; it brings stability to our society. For those who choose to marry, and for their children, marriage provides an abundance of legal, financial, and social benefits. In return it imposes weighty legal, financial, and social obligations. The question before us is whether, consistent with the Massachusetts Constitution, the Commonwealth may deny the protections, benefits, and obligations conferred by civil marriage to two individuals of the same sex who wish to marry. We conclude that it may not. The Massachusetts Constitution affirms the dignity and equality of all individuals. It forbids the creation of second-class citizens. In reaching our conclusion we have given full deference to the arguments made by the Commonwealth. But it has failed to identify any constitutionally adequate reason for denying civil marriage to same-sex couples.

We are mindful that our decision marks a change in the history of our marriage law. Many people hold deep-seated religious, moral, and ethical convictions that marriage should be limited to the union of one man and one woman, and that homosexual conduct is immoral. Many hold equally strong religious, moral, and ethical convictions that same-sex couples are entitled to be married, and that homosexual persons should be treated no differently than their heterosexual neighbors. Neither view answers the question before us. Our concern is with the Massachusetts Constitution as a charter of governance for every person properly within its reach. “Our obligation is to define the liberty of all, not to mandate our own moral code.” Lawrence v. Texas, 123 S.Ct. 2472, 2480 (2003) (Lawrence ), quoting Planned Parenthood of Southeastern Pa. v. Casey, 505 U.S. 833, 850 (1992).

Whether the Commonwealth may use its formidable regulatory authority to bar same-sex couples from civil marriage is a question not previously addressed by a Massachusetts appellate court. [FN3] It is a question the United States Supreme Court left open as a matter of Federal law in Lawrence, supra at 2484, where it was not an issue. There, the Court affirmed that the core concept of common human dignity protected by the Fourteenth Amendment to the United States Constitution precludes government intrusion into the deeply personal realms of consensual adult expressions of intimacy and one’s choice of an intimate partner. The Court also reaffirmed the central role that decisions whether to marry or have children bear in shaping one’s identity. Id. at 2481. The Massachusetts Constitution is, if anything, more protective of individual liberty and equality than the Federal Constitution; it may demand broader protection for fundamental rights; and it is less tolerant of government intrusion into the protected spheres of private life.

Barred access to the protections, benefits, and obligations of civil marriage, a person who enters into an intimate, exclusive union with another of the same sex is arbitrarily deprived of membership in one of our community’s most rewarding and cherished institutions. That exclusion is incompatible with the constitutional principles of respect for individual autonomy and equality under law.

I

The plaintiffs are fourteen individuals from five Massachusetts counties. As of April 11, 2001, the date they filed their complaint, the plaintiffs Gloria Bailey, sixty years old, and Linda Davies, fifty-five years old, had been in a committed relationship for thirty years; the plaintiffs Maureen Brodoff, forty-nine years old, and Ellen Wade, fifty-two years old, had been in a committed relationship for twenty years and lived with their twelve year old daughter; the plaintiffs Hillary Goodridge, forty-four years old, and Julie Goodridge, forty-three years old, had been in a committed relationship for thirteen years and lived with their five year old daughter; the plaintiffs Gary Chalmers, thirty-five years old, and Richard Linnell, thirty-seven years old, had been in a committed relationship for thirteen years and lived with their eight year old daughter and Richard’s mother; the plaintiffs Heidi Norton, thirty-six years old, and Gina Smith, thirty-six years old, had been in a committed relationship for eleven years and lived with their two sons, ages five years and one year; the plaintiffs Michael Horgan, forty-one years old, and David Balmelli, forty-one years old, had been in a committed relationship for seven years; and the plaintiffs David Wilson, fifty-seven years old, and Robert Compton, fifty-one years old, had been in a committed relationship for four years and had cared for David’s mother in their home after a serious illness until she died.

The plaintiffs include business executives, lawyers, an investment banker, educators, therapists, and a computer engineer. Many are active in church, community, and school groups. They have employed such legal means as are available to them—for example, joint adoption, powers of attorney, and joint ownership of real property—to secure aspects of their relationships. Each plaintiff attests a desire to marry his or her partner in order to affirm publicly their commitment to each other and to secure the legal protections and benefits afforded to married couples and their children.

The Department of Public Health (department) is charged by statute with safeguarding public health. See G.L. c. 17. Among its responsibilities, the department oversees the registry of vital records and statistics (registry), which “enforce[s] all laws” relative to the issuance of marriage licenses and the keeping of marriage records, see G.L. c. 17, § 4, and which promulgates policies and procedures for the issuance of marriage licenses by city and town clerks and registers. See, e.g., G.L. c. 207, §§ 20, 28A, and 37. The registry is headed by a registrar of vital records and statistics (registrar), appointed by the Commissioner of Public Health (commissioner) with the approval of the public health council and supervised by the commissioner. See G.L. c. 17, § 4.

In March and April, 2001, each of the plaintiff couples attempted to obtain a marriage license from a city or town clerk’s office. As required under G.L. c. 207, they completed notices of intention to marry on forms provided by the registry, see G.L. c. 207, § 20, and presented these forms to a Massachusetts town or city clerk, together with the required health forms and marriage license fees. See G.L. c. 207, § 19. In each case, the clerk either refused to accept the notice of intention to marry or denied a marriage license to the couple on the ground that Massachusetts does not recognize same- sex marriage. [FN4], [FN5] Because obtaining a marriage license is a necessary prerequisite to civil marriage in Massachusetts, denying marriage licenses to the plaintiffs was tantamount to denying them access to civil marriage itself, with its appurtenant social and legal protections, benefits, and obligations. [FN6]

On April 11, 2001, the plaintiffs filed suit in the Superior Court against the department and the commissioner seeking a judgment that “the exclusion of the [p]laintiff couples and other qualified same-sex couples from access to marriage licenses, and the legal and social status of civil marriage, as well as the protections, benefits and obligations of marriage, violates Massachusetts law.” See G.L. c. 231A. The plaintiffs alleged violation of the laws of the Commonwealth, including but not limited to their rights under arts. 1, 6, 7, 10, 12, and 16, and Part II, c. 1, § 1, art. 4, of the Massachusetts Constitution. [FN7], [FN8]

The department, represented by the Attorney General, admitted to a policy and practice of denying marriage licenses to same-sex couples. It denied that its actions violated any law or that the plaintiffs were entitled to relief. The parties filed cross motions for summary judgment.

A Superior Court judge ruled for the department. In a memorandum of decision and order dated May 7, 2002, he dismissed the plaintiffs’ claim that the marriage statutes should be construed to permit marriage between persons of the same sex, holding that the plain wording of G.L. c. 207, as well as the wording of other marriage statutes, precluded that interpretation. Turning to the constitutional claims, he held that the marriage exclusion does not offend the liberty, freedom, equality, or due process provisions of the Massachusetts Constitution, and that the Massachusetts Declaration of Rights does not guarantee “the fundamental right to marry a person of the same sex.” He concluded that prohibiting same-sex marriage rationally furthers the Legislature’s legitimate interest in safeguarding the “primary purpose” of marriage, “procreation.” The Legislature may rationally limit marriage to opposite-sex couples, he concluded, because those couples are “theoretically ... capable of procreation,” they do not rely on “inherently more cumbersome” noncoital means of reproduction, and they are more likely than same-sex couples to have children, or more children.

After the complaint was dismissed and summary judgment entered for the defendants, the plaintiffs appealed. Both parties requested direct appellate review, which we granted.

II

Although the plaintiffs refer in passing to “the marriage statutes,” they focus, quite properly, on G.L. c. 207, the marriage licensing statute, which controls entry into civil marriage. As a preliminary matter, we summarize the provisions of that law.

General Laws c. 207 is both a gatekeeping and a public records statute. It sets minimum qualifications for obtaining a marriage license and directs city and town clerks, the registrar, and the department to keep and maintain certain “vital records” of civil marriages. The gatekeeping provisions of G.L. c. 207 are minimal. They forbid marriage of individuals within certain degrees of consanguinity, §§ 1 and 2, and polygamous marriages. See G.L. c. 207, § 4. See also G.L. c. 207, § 8 (marriages solemnized in violation of §§ 1, 2, and 4, are void ab initio). They prohibit marriage if one of the parties has communicable syphilis, see G.L. c. 207, § 28A, and restrict the circumstances in which a person under eighteen years of age may marry. See G.L. c. 207, §§ 7, 25, and 27. The statute requires that civil marriage be solemnized only by those so authorized. See G.L. c. 207, §§ 38-40.

The record-keeping provisions of G.L. c. 207 are more extensive. Marriage applicants file standard information forms and a medical certificate in any Massachusetts city or town clerk’s office and tender a filing fee. G.L. c. 207, §§ 19-20, 28A. The clerk issues the marriage license, and when the marriage is solemnized, the individual authorized to solemnize the marriage adds additional information to the form and returns it (or a copy) to the clerk’s office. G.L. c. 207, §§ 28, 30, 38-40 (this completed form is commonly known as the “marriage certificate”). The clerk sends a copy of the information to the registrar, and that information becomes a public record. See G.L. c. 17, § 4; G.L. c. 66, § 10. [FN9], [FN10]

In short, for all the joy and solemnity that normally attend a marriage, G.L. c. 207, governing entrance to marriage, is a licensing law. The plaintiffs argue that because nothing in that licensing law specifically prohibits marriages between persons of the same sex, we may interpret the statute to permit “qualified same sex couples” to obtain marriage licenses, thereby avoiding the question whether the law is constitutional. See School Comm. of Greenfield v. Greenfield Educ. Ass’n, 385 Mass. 70, 79 (1982), and cases cited. This claim lacks merit.

We interpret statutes to carry out the Legislature’s intent, determined by the words of a statute interpreted according to “the ordinary and approved usage of the language.” Hanlon v. Rollins, 286 Mass. 444, 447 (1934). The everyday meaning of “marriage” is ”[t]he legal union of a man and woman as husband and wife,” Black’s Law Dictionary 986 (7th ed.1999), and the plaintiffs do not argue that the term “marriage” has ever had a different meaning under Massachusetts law. See, e.g., Milford v. Worcester, 7 Mass. 48, 52 (1810) (marriage “is an engagement, by which a single man and a single woman, of sufficient discretion, take each other for husband and wife”). This definition of marriage, as both the department and the Superior Court judge point out, derives from the common law. See Commonwealth v. Knowlton, 2 Mass. 530, 535 (1807) (Massachusetts common law derives from English common law except as otherwise altered by Massachusetts statutes and Constitution). See also Commonwealth v. Lane, 113 Mass. 458, 462-463 (1873) (“when the statutes are silent, questions of the validity of marriages are to be determined by the jus gentium, the common law of nations”); C.P. Kindregan, Jr., & M.L. Inker, Family Law and Practice § 1.2 (3d ed.2002). Far from being ambiguous, the undefined word “marriage,” as used in G.L. c. 207, confirms the General Court’s intent to hew to the term’s common-law and quotidian meaning concerning the genders of the marriage partners.

The intended scope of G.L. c. 207 is also evident in its consanguinity provisions. See Chandler v. County Comm’rs of Nantucket County, 437 Mass. 430, 435 (2002) (statute’s various provisions may offer insight into legislative intent). Sections 1 and 2 of G.L. c. 207 prohibit marriages between a man and certain female relatives and a woman and certain male relatives, but are silent as to the consanguinity of male-male or female-female marriage applicants. See G.L. c. 207, §§ 1-2. The only reasonable explanation is that the Legislature did not intend that same-sex couples be licensed to marry. We conclude, as did the judge, that G.L. c. 207 may not be construed to permit same-sex couples to marry. [FN11]

III
A

The larger question is whether, as the department claims, government action that bars same-sex couples from civil marriage constitutes a legitimate exercise of the State’s authority to regulate conduct, or whether, as the plaintiffs claim, this categorical marriage exclusion violates the Massachusetts Constitution. We have recognized the long-standing statutory understanding, derived from the common law, that “marriage” means the lawful union of a woman and a man. But that history cannot and does not foreclose the constitutional question.

The plaintiffs’ claim that the marriage restriction violates the Massachusetts Constitution can be analyzed in two ways. Does it offend the Constitution’s guarantees of equality before the law? Or do the liberty and due process provisions of the Massachusetts Constitution secure the plaintiffs’ right to marry their chosen partner? In matters implicating marriage, family life, and the upbringing of children, the two constitutional concepts frequently overlap, as they do here. See, e.g., M.L.B. v. S.L.J., 519 U.S. 102, 120 (1996) (noting convergence of due process and equal protection principles in cases concerning parent-child relationships); Perez v. Sharp, 32 Cal.2d 711, 728 (1948) (analyzing statutory ban on interracial marriage as equal protection violation concerning regulation of fundamental right). See also Lawrence, supra at 2482 (“Equality of treatment and the due process right to demand respect for conduct protected by the substantive guarantee of liberty are linked in important respects, and a decision on the latter point advances both interests”); Bolling v. Sharpe, 347 U.S. 497 (1954) (racial segregation in District of Columbia public schools violates the due process clause of the Fifth Amendment to the United States Constitution), decided the same day as Brown v. Board of Educ. of Topeka, 347 U.S. 483 (1954) (holding that segregation of public schools in the States violates the equal protection clause of the Fourteenth Amendment). Much of what we say concerning one standard applies to the other.

We begin by considering the nature of civil marriage itself. Simply put, the government creates civil marriage. In Massachusetts, civil marriage is, and since pre-Colonial days has been, precisely what its name implies: a wholly secular institution. See Commonwealth v. Munson, 127 Mass. 459, 460-466 (1879) (noting that ”[i]n Massachusetts, from very early times, the requisites of a valid marriage have been regulated by statutes of the Colony, Province, and Commonwealth,” and surveying marriage statutes from 1639 through 1834). No religious ceremony has ever been required to validate a Massachusetts marriage. Id.

In a real sense, there are three partners to every civil marriage: two willing spouses and an approving State. See DeMatteo v. DeMatteo, 436 Mass. 18, 31 (2002) (“Marriage is not a mere contract between two parties but a legal status from which certain rights and obligations arise”); Smith v. Smith, 171 Mass. 404, 409 (1898) (on marriage, the parties “assume[ ] new relations to each other and to the State”). See also French v. McAnarney, 290 Mass. 544, 546 (1935). While only the parties can mutually assent to marriage, the terms of the marriage—who may marry and what obligations, benefits, and liabilities attach to civil marriage—are set by the Commonwealth. Conversely, while only the parties can agree to end the marriage (absent the death of one of them or a marriage void ab initio), the Commonwealth defines the exit terms. See G.L. c. 208.

Civil marriage is created and regulated through exercise of the police power. See Commonwealth v. Stowell, 389 Mass. 171, 175 (1983) (regulation of marriage is properly within the scope of the police power). “Police power” (now more commonly termed the State’s regulatory authority) is an old-fashioned term for the Commonwealth’s lawmaking authority, as bounded by the liberty and equality guarantees of the Massachusetts Constitution and its express delegation of power from the people to their government. In broad terms, it is the Legislature’s power to enact rules to regulate conduct, to the extent that such laws are “necessary to secure the health, safety, good order, comfort, or general welfare of the community” (citations omitted). Opinion of the Justices, 341 Mass. 760, 785 (1960). [FN12] See Commonwealth v. Alger, 7 Cush. 53, 85 (1851).

Without question, civil marriage enhances the “welfare of the community.” It is a “social institution of the highest importance.” French v. McAnarney, supra. Civil marriage anchors an ordered society by encouraging stable relationships over transient ones. It is central to the way the Commonwealth identifies individuals, provides for the orderly distribution of property, ensures that children and adults are cared for and supported whenever possible from private rather than public funds, and tracks important epidemiological and demographic data.

Marriage also bestows enormous private and social advantages on those who choose to marry. Civil marriage is at once a deeply personal commitment to another human being and a highly public celebration of the ideals of mutuality, companionship, intimacy, fidelity, and family. “It is an association that promotes a way of life, not causes; a harmony in living, not political faiths; a bilateral loyalty, not commercial or social projects.” Griswold v. Connecticut, 381 U.S. 479, 486 (1965). Because it fulfils yearnings for security, safe haven, and connection that express our common humanity, civil marriage is an esteemed institution, and the decision whether and whom to marry is among life’s momentous acts of self-definition.

Tangible as well as intangible benefits flow from marriage. The marriage license grants valuable property rights to those who meet the entry requirements, and who agree to what might otherwise be a burdensome degree of government regulation of their activities. [FN13] See Leduc v. Commonwealth, 421 Mass. 433, 435 (1995), cert. denied, 519 U.S. 827 (1996) ( “The historical aim of licensure generally is preservation of public health, safety, and welfare by extending the public trust only to those with proven qualifications”). The Legislature has conferred on “each party [in a civil marriage] substantial rights concerning the assets of the other which unmarried cohabitants do not have.” Wilcox v. Trautz, 427 Mass. 326, 334 (1998). See Collins v. Guggenheim, 417 Mass. 615, 618 (1994) (rejecting claim for equitable distribution of property where plaintiff cohabited with but did not marry defendant); Feliciano v. Rosemar Silver Co., 401 Mass. 141, 142 (1987) (government interest in promoting marriage would be “subverted” by recognition of “a right to recover for loss of consortium by a person who has not accepted the correlative responsibilities of marriage”); Davis v. Misiano, 373 Mass. 261, 263 (1977) (unmarried partners not entitled to rights of separate support or alimony). See generally Attorney Gen. v. Desilets, 418 Mass. 316, 327-328 & nn. 10, 11 (1994).

The benefits accessible only by way of a marriage license are enormous, touching nearly every aspect of life and death. The department states that “hundreds of statutes” are related to marriage and to marital benefits. With no attempt to be comprehensive, we note that some of the statutory benefits conferred by the Legislature on those who enter into civil marriage include, as to property: joint Massachusetts income tax filing (G.L. c. 62C, § 6); tenancy by the entirety (a form of ownership that provides certain protections against creditors and allows for the automatic descent of property to the surviving spouse without probate) (G.L. c. 184, § 7); extension of the benefit of the homestead protection (securing up to $300,000 in equity from creditors) to one’s spouse and children (G.L. c. 188, § 1); automatic rights to inherit the property of a deceased spouse who does not leave a will (G.L. c. 190, § 1); the rights of elective share and of dower (which allow surviving spouses certain property rights where the decedent spouse has not made adequate provision for the survivor in a will) (G.L. c. 191, § 15, and G.L. c. 189); entitlement to wages owed to a deceased employee (G.L. c. 149, § 178A [general] and G.L. c. 149, § 178C [public employees] ); eligibility to continue certain businesses of a deceased spouse (e.g., G.L. c. 112, § 53 [dentist] ); the right to share the medical policy of one’s spouse (e.g., G.L. c. 175, § 108, Second [a ] [3] [defining an insured’s “dependent” to include one’s spouse), see Connors v. Boston, 430 Mass. 31, 43 (1999) [domestic partners of city employees not included within the term “dependent” as used in G.L. c. 32B, § 2] ); thirty-nine week continuation of health coverage for the spouse of a person who is laid off or dies (e.g., G.L. c. 175, § 110G); preferential options under the Commonwealth’s pension system (see G.L. c. 32, § 12[2] [“Joint and Last Survivor Allowance”] ); preferential benefits in the Commonwealth’s medical program, MassHealth (e.g., 130 Code Mass. Regs. § 515.012[A] prohibiting placing a lien on long-term care patient’s former home if spouse still lives there); access to veterans’ spousal benefits and preferences (e.g., G.L. c. 115, § 1 [defining “dependents”] and G.L. c. 31, § 26 [State employment] and § 28 [municipal employees] ); financial protections for spouses of certain Commonwealth employees (fire fighters, police officers, prosecutors, among others) killed in the performance of duty (e.g., G.L. c. 32, §§ 100-103); the equitable division of marital property on divorce (G.L. c. 208, § 34); temporary and permanent alimony rights (G.L. c. 208, §§ 17 and 34); the right to separate support on separation of the parties that does not result in divorce (G.L. c. 209, § 32); and the right to bring claims for wrongful death and loss of consortium, and for funeral and burial expenses and punitive damages resulting from tort actions (G.L. c. 229, §§ 1 and 2; G.L. c. 228, § 1. See Feliciano v. Rosemar Silver Co., supra ).

Exclusive marital benefits that are not directly tied to property rights include the presumptions of legitimacy and parentage of children born to a married couple (G.L. c. 209C, § 6, and G.L. c. 46, § 4B); and evidentiary rights, such as the prohibition against spouses testifying against one another about their private conversations, applicable in both civil and criminal cases (G.L. c. 233, § 20). Other statutory benefits of a personal nature available only to married individuals include qualification for bereavement or medical leave to care for individuals related by blood or marriage (G.L. c. 149, § 52D); an automatic “family member” preference to make medical decisions for an incompetent or disabled spouse who does not have a contrary health care proxy, see Shine v. Vega, 429 Mass. 456, 466 (1999); the application of predictable rules of child custody, visitation, support, and removal out-of-State when married parents divorce (e.g., G.L. c. 208, § 19 [temporary custody], § 20 [temporary support], § 28 [custody and support on judgment of divorce], § 30 [removal from Commonwealth], and § 31 [shared custody plan]; priority rights to administer the estate of a deceased spouse who dies without a will, and requirement that surviving spouse must consent to the appointment of any other person as administrator (G.L. c. 38, § 13 [disposition of body], and G.L. c. 113, § 8 [anatomical gifts] ); and the right to interment in the lot or tomb owned by one’s deceased spouse (G.L. c. 114, §§ 29-33).

Where a married couple has children, their children are also directly or indirectly, but no less auspiciously, the recipients of the special legal and economic protections obtained by civil marriage. Notwithstanding the Commonwealth’s strong public policy to abolish legal distinctions between marital and nonmarital children in providing for the support and care of minors, see Department of Revenue v. Mason M., 439 Mass. 665 (2003); Woodward v. Commissioner of Social Sec., 435 Mass. 536, 546 (2002), the fact remains that marital children reap a measure of family stability and economic security based on their parents’ legally privileged status that is largely inaccessible, or not as readily accessible, to nonmarital children. Some of these benefits are social, such as the enhanced approval that still attends the status of being a marital child. Others are material, such as the greater ease of access to family-based State and Federal benefits that attend the presumptions of one’s parentage.

It is undoubtedly for these concrete reasons, as well as for its intimately personal significance, that civil marriage has long been termed a “civil right.” See, e.g., Loving v. Virginia, 388 U.S. 1, 12 (1967) (“Marriage is one of the ‘basic civil rights of man,’ fundamental to our very existence and survival”), quoting Skinner v. Oklahoma, 316 U.S. 535, 541 (1942); Milford v. Worcester, 7 Mass. 48, 56 (1810) (referring to “civil rights incident to marriages”). See also Baehr v. Lewin, 74 Haw. 530, 561 (1993) (identifying marriage as a “civil right[ ]”); Baker v. State, 170 Vt. 194, 242 (1999) (Johnson, J., concurring in part and dissenting in part) (same). The United States Supreme Court has described the right to marry as “of fundamental importance for all individuals” and as “part of the fundamental ‘right of privacy’ implicit in the Fourteenth Amendment’s Due Process Clause.” Zablocki v. Redhail, 434 U.S. 374, 384 (1978). See Loving v. Virginia, supra (“The freedom to marry has long been recognized as one of the vital personal rights essential to the orderly pursuit of happiness by free men”). [FN14]

Without the right to marry—or more properly, the right to choose to marry—one is excluded from the full range of human experience and denied full protection of the laws for one’s “avowed commitment to an intimate and lasting human relationship.” Baker v. State, supra at 229. Because civil marriage is central to the lives of individuals and the welfare of the community, our laws assiduously protect the individual’s right to marry against undue government incursion. Laws may not “interfere directly and substantially with the right to marry.” Zablocki v. Redhail, supra at 387. See Perez v. Sharp, 32 Cal.2d 711, 714 (1948) (“There can be no prohibition of marriage except for an important social objective and reasonable means”). [FN15]

Unquestionably, the regulatory power of the Commonwealth over civil marriage is broad, as is the Commonwealth’s discretion to award public benefits. See Commonwealth v. Stowell, 389 Mass. 171, 175 (1983) (marriage); Moe v. Secretary of Admin. & Fin., 382 Mass. 629, 652 (1981) (Medicaid benefits). Individuals who have the choice to marry each other and nevertheless choose not to may properly be denied the legal benefits of marriage. See Wilcox v. Trautz, 427 Mass. 326, 334 (1998); Collins v. Guggenheim, 417 Mass. 615, 618 (1994); Feliciano v. Rosemar Silver Co., 401 Mass. 141, 142 (1987). But that same logic cannot hold for a qualified individual who would marry if she or he only could.

B

For decades, indeed centuries, in much of this country (including Massachusetts) no lawful marriage was possible between white and black Americans. That long history availed not when the Supreme Court of California held in 1948 that a legislative prohibition against interracial marriage violated the due process and equality guarantees of the Fourteenth Amendment, Perez v. Sharp, 32 Cal.2d 711, 728 (1948), or when, nineteen years later, the United States Supreme Court also held that a statutory bar to interracial marriage violated the Fourteenth Amendment, Loving v. Virginia, 388 U.S. 1 (1967). [FN16] As both Perez and Loving make clear, the right to marry means little if it does not include the right to marry the person of one’s choice, subject to appropriate government restrictions in the interests of public health, safety, and welfare. See Perez v. Sharp, supra at 717 (“the essence of the right to marry is freedom to join in marriage with the person of one’s choice”). See also Loving v. Virginia, supra at 12. In this case, as in Perez and Loving, a statute deprives individuals of access to an institution of fundamental legal, personal, and social significance—the institution of marriage—because of a single trait: skin color in Perez and Loving, sexual orientation here. As it did in Perez and Loving, history must yield to a more fully developed understanding of the invidious quality of the discrimination. [FN17]

The Massachusetts Constitution protects matters of personal liberty against government incursion as zealously, and often more so, than does the Federal Constitution, even where both Constitutions employ essentially the same language. See Planned Parenthood League of Mass., Inc. v. Attorney Gen., 424 Mass. 586, 590 (1997); Corning Glass Works v. Ann & Hope, Inc. of Danvers, 363 Mass. 409, 416 (1973). That the Massachusetts Constitution is in some instances more protective of individual liberty interests than is the Federal Constitution is not surprising. Fundamental to the vigor of our Federal system of government is that “state courts are absolutely free to interpret state constitutional provisions to accord greater protection to individual rights than do similar provisions of the United States Constitution.” Arizona v. Evans, 514 U.S. 1, 8 (1995). [FN18]

The individual liberty and equality safeguards of the Massachusetts Constitution protect both “freedom from” unwarranted government intrusion into protected spheres of life and “freedom to” partake in benefits created by the State for the common good. See Bachrach v. Secretary of the Commonwealth, 382 Mass. 268, 273 (1981); Dalli v. Board of Educ., 358 Mass. 753, 759 (1971). Both freedoms are involved here. Whether and whom to marry, how to express sexual intimacy, and whether and how to establish a family—these are among the most basic of every individual’s liberty and due process rights. See, e.g., Lawrence, supra at 2481; Planned Parenthood of Southeastern Pa. v. Casey, 505 U.S. 833, 851 (1992); Zablocki v. Redhail, 434 U.S. 374, 384 (1978); Roe v. Wade, 410 U.S. 113, 152-153 (1973); Eisenstadt v. Baird, 405 U.S. 438, 453 (1972); Loving v. Virginia, supra. And central to personal freedom and security is the assurance that the laws will apply equally to persons in similar situations. “Absolute equality before the law is a fundamental principle of our own Constitution.” Opinion of the Justices, 211 Mass. 618, 619 (1912). The liberty interest in choosing whether and whom to marry would be hollow if the Commonwealth could, without sufficient justification, foreclose an individual from freely choosing the person with whom to share an exclusive commitment in the unique institution of civil marriage.

The Massachusetts Constitution requires, at a minimum, that the exercise of the State’s regulatory authority not be “arbitrary or capricious.” Commonwealth v. Henry’s Drywall Co., 366 Mass. 539, 542 (1974). [FN19] Under both the equality and liberty guarantees, regulatory authority must, at very least, serve “a legitimate purpose in a rational way”; a statute must “bear a reasonable relation to a permissible legislative objective.” Rushworth v. Registrar of Motor Vehicles, 413 Mass. 265, 270 (1992). See, e.g., Massachusetts Fed’n of Teachers v. Board of Educ., 436 Mass. 763, 778 (2002) (equal protection); Coffee-Rich, Inc. v. Commissioner of Pub. Health, 348 Mass. 414, 422 (1965) (due process). Any law failing to satisfy the basic standards of rationality is void.

The plaintiffs challenge the marriage statute on both equal protection and due process grounds. With respect to each such claim, we must first determine the appropriate standard of review. Where a statute implicates a fundamental right or uses a suspect classification, we employ “strict judicial scrutiny.” Lowell v. Kowalski, 380 Mass. 663, 666 (1980). For all other statutes, we employ the ” ‘rational basis’ test.” English v. New England Med. Ctr., 405 Mass. 423, 428 (1989). For due process claims, rational basis analysis requires that statutes “bear[ ] a real and substantial relation to the public health, safety, morals, or some other phase of the general welfare.” Coffee-Rich, Inc. v. Commissioner of Pub. Health, supra, quoting Sperry & Hutchinson Co. v. Director of the Div. on the Necessaries of Life, 307 Mass. 408, 418 (1940). For equal protection challenges, the rational basis test requires that “an impartial lawmaker could logically believe that the classification would serve a legitimate public purpose that transcends the harm to the members of the disadvantaged class.” English v. New England Med. Ctr., supra at 429, quoting Cleburne v. Cleburne Living Ctr., Inc., 473 U.S. 432, 452 (1985) (Stevens, J., concurring). [FN20]

The department argues that no fundamental right or “suspect” class is at issue here, [FN21] and rational basis is the appropriate standard of review. For the reasons we explain below, we conclude that the marriage ban does not meet the rational basis test for either due process or equal protection. Because the statute does not survive rational basis review, we do not consider the plaintiffs’ arguments that this case merits strict judicial scrutiny.

The department posits three legislative rationales for prohibiting same-sex couples from marrying: (1) providing a “favorable setting for procreation”; (2) ensuring the optimal setting for child rearing, which the department defines as “a two-parent family with one parent of each sex”; and (3) preserving scarce State and private financial resources. We consider each in turn.

The judge in the Superior Court endorsed the first rationale, holding that “the state’s interest in regulating marriage is based on the traditional concept that marriage’s primary purpose is procreation.” This is incorrect. Our laws of civil marriage do not privilege procreative heterosexual intercourse between married people above every other form of adult intimacy and every other means of creating a family. General Laws c. 207 contains no requirement that the applicants for a marriage license attest to their ability or intention to conceive children by coitus. Fertility is not a condition of marriage, nor is it grounds for divorce. People who have never consummated their marriage, and never plan to, may be and stay married. See Franklin v. Franklin, 154 Mass. 515, 516 (1891) (“The consummation of a marriage by coition is not necessary to its validity”). [FN22] People who cannot stir from their deathbed may marry. See G.L. c. 207, § 28A. While it is certainly true that many, perhaps most, married couples have children together (assisted or unassisted), it is the exclusive and permanent commitment of the marriage partners to one another, not the begetting of children, that is the sine qua non of civil marriage. [FN23]

Moreover, the Commonwealth affirmatively facilitates bringing children into a family regardless of whether the intended parent is married or unmarried, whether the child is adopted or born into a family, whether assistive technology was used to conceive the child, and whether the parent or her partner is heterosexual, homosexual, or bisexual. [FN24] If procreation were a necessary component of civil marriage, our statutes would draw a tighter circle around the permissible bounds of nonmarital child bearing and the creation of families by noncoital means. The attempt to isolate procreation as “the source of a fundamental right to marry,” post at (Cordy, J., dissenting), overlooks the integrated way in which courts have examined the complex and overlapping realms of personal autonomy, marriage, family life, and child rearing. Our jurisprudence recognizes that, in these nuanced and fundamentally private areas of life, such a narrow focus is inappropriate.

The “marriage is procreation” argument singles out the one unbridgeable difference between same-sex and opposite-sex couples, and transforms that difference into the essence of legal marriage. Like “Amendment 2” to the Constitution of Colorado, which effectively denied homosexual persons equality under the law and full access to the political process, the marriage restriction impermissibly “identifies persons by a single trait and then denies them protection across the board.” Romer v. Evans, 517 U.S. 620, 633 (1996). In so doing, the State’s action confers an official stamp of approval on the destructive stereotype that same-sex relationships are inherently unstable and inferior to opposite-sex relationships and are not worthy of respect. [FN25]

The department’s first stated rationale, equating marriage with unassisted heterosexual procreation, shades imperceptibly into its second: that confining marriage to opposite-sex couples ensures that children are raised in the “optimal” setting. Protecting the welfare of children is a paramount State policy. Restricting marriage to opposite-sex couples, however, cannot plausibly further this policy. “The demographic changes of the past century make it difficult to speak of an average American family. The composition of families varies greatly from household to household.” Troxel v. Granville, 530 U.S. 57, 63 (2000). Massachusetts has responded supportively to “the changing realities of the American family,” id. at 64, and has moved vigorously to strengthen the modern family in its many variations. See, e.g., G.L. c. 209C (paternity statute); G.L. c. 119, § 39D (grandparent visitation statute); Blixt v. Blixt, 437 Mass. 649 (2002), cert. denied, 537 U.S. 1189 (2003) (same); E.N.O. v. L.M.M., 429 Mass. 824, cert. denied, 528 U.S. 1005 (1999) (de facto parent); Youmans v. Ramos, 429 Mass. 774, 782 (1999) (same); and Adoption of Tammy, 416 Mass. 205 (1993) (coparent adoption). Moreover, we have repudiated the common-law power of the State to provide varying levels of protection to children based on the circumstances of birth. See G.L. c. 209C (paternity statute); Powers v. Wilkinson, 399 Mass. 650, 661 (1987) (“Ours is an era in which logic and compassion have impelled the law toward unburdening children from the stigma and the disadvantages heretofore attendant upon the status of illegitimacy”). The “best interests of the child” standard does not turn on a parent’s sexual orientation or marital status. See e.g., Doe v. Doe, 16 Mass.App.Ct. 499, 503 (1983) (parent’s sexual orientation insufficient ground to deny custody of child in divorce action). See also E.N.O. v. L.M.M., supra at 829-830 (best interests of child determined by considering child’s relationship with biological and de facto same-sex parents); Silvia v. Silvia, 9 Mass.App.Ct. 339, 341 & n. 3 (1980) (collecting support and custody statutes containing no gender distinction).

The department has offered no evidence that forbidding marriage to people of the same sex will increase the number of couples choosing to enter into opposite-sex marriages in order to have and raise children. There is thus no rational relationship between the marriage statute and the Commonwealth’s proffered goal of protecting the “optimal” child rearing unit. Moreover, the department readily concedes that people in same-sex couples may be “excellent” parents. These couples (including four of the plaintiff couples) have children for the reasons others do—to love them, to care for them, to nurture them. But the task of child rearing for same-sex couples is made infinitely harder by their status as outliers to the marriage laws. While establishing the parentage of children as soon as possible is crucial to the safety and welfare of children, see Culliton v. Beth Israel Deaconness Med. Ctr., 435 Mass. 285, 292 (2001), same-sex couples must undergo the sometimes lengthy and intrusive process of second-parent adoption to establish their joint parentage. While the enhanced income provided by marital benefits is an important source of security and stability for married couples and their children, those benefits are denied to families headed by same-sex couples. See, e.g., note 6, supra. While the laws of divorce provide clear and reasonably predictable guidelines for child support, child custody, and property division on dissolution of a marriage, same-sex couples who dissolve their relationships find themselves and their children in the highly unpredictable terrain of equity jurisdiction. See E.N.O. v. L.M.M., supra. Given the wide range of public benefits reserved only for married couples, we do not credit the department’s contention that the absence of access to civil marriage amounts to little more than an inconvenience to same-sex couples and their children. Excluding same-sex couples from civil marriage will not make children of opposite-sex marriages more secure, but it does prevent children of same-sex couples from enjoying the immeasurable advantages that flow from the assurance of “a stable family structure in which children will be reared, educated, and socialized.” Post at (Cordy, J., dissenting). [FN26]

No one disputes that the plaintiff couples are families, that many are parents, and that the children they are raising, like all children, need and should have the fullest opportunity to grow up in a secure, protected family unit. Similarly, no one disputes that, under the rubric of marriage, the State provides a cornucopia of substantial benefits to married parents and their children. The preferential treatment of civil marriage reflects the Legislature’s conclusion that marriage “is the foremost setting for the education and socialization of children” precisely because it “encourages parents to remain committed to each other and to their children as they grow.” Post at (Cordy, J., dissenting).

In this case, we are confronted with an entire, sizeable class of parents raising children who have absolutely no access to civil marriage and its protections because they are forbidden from procuring a marriage license. It cannot be rational under our laws, and indeed it is not permitted, to penalize children by depriving them of State benefits because the State disapproves of their parents’ sexual orientation.

The third rationale advanced by the department is that limiting marriage to opposite-sex couples furthers the Legislature’s interest in conserving scarce State and private financial resources. The marriage restriction is rational, it argues, because the General Court logically could assume that same-sex couples are more financially independent than married couples and thus less needy of public marital benefits, such as tax advantages, or private marital benefits, such as employer-financed health plans that include spouses in their coverage.

An absolute statutory ban on same-sex marriage bears no rational relationship to the goal of economy. First, the department’s conclusory generalization— that same-sex couples are less financially dependent on each other than opposite-sex couples—ignores that many same-sex couples, such as many of the plaintiffs in this case, have children and other dependents (here, aged parents) in their care. [FN27] The department does not contend, nor could it, that these dependents are less needy or deserving than the dependents of married couples. Second, Massachusetts marriage laws do not condition receipt of public and private financial benefits to married individuals on a demonstration of financial dependence on each other; the benefits are available to married couples regardless of whether they mingle their finances or actually depend on each other for support.

The department suggests additional rationales for prohibiting same-sex couples from marrying, which are developed by some amici. It argues that broadening civil marriage to include same-sex couples will trivialize or destroy the institution of marriage as it has historically been fashioned. Certainly our decision today marks a significant change in the definition of marriage as it has been inherited from the common law, and understood by many societies for centuries. But it does not disturb the fundamental value of marriage in our society.

Here, the plaintiffs seek only to be married, not to undermine the institution of civil marriage. They do not want marriage abolished. They do not attack the binary nature of marriage, the consanguinity provisions, or any of the other gate-keeping provisions of the marriage licensing law. Recognizing the right of an individual to marry a person of the same sex will not diminish the validity or dignity of opposite-sex marriage, any more than recognizing the right of an individual to marry a person of a different race devalues the marriage of a person who marries someone of her own race. [FN28] If anything, extending civil marriage to same-sex couples reinforces the importance of marriage to individuals and communities. That same-sex couples are willing to embrace marriage’s solemn obligations of exclusivity, mutual support, and commitment to one another is a testament to the enduring place of marriage in our laws and in the human spirit. [FN29]

It has been argued that, due to the State’s strong interest in the institution of marriage as a stabilizing social structure, only the Legislature can control and define its boundaries. Accordingly, our elected representatives legitimately may choose to exclude same-sex couples from civil marriage in order to assure all citizens of the Commonwealth that (1) the benefits of our marriage laws are available explicitly to create and support a family setting that is, in the Legislature’s view, optimal for child rearing, and (2) the State does not endorse gay and lesbian parenthood as the equivalent of being raised by one’s married biological parents. [FN30] These arguments miss the point. The Massachusetts Constitution requires that legislation meet certain criteria and not extend beyond certain limits. It is the function of courts to determine whether these criteria are met and whether these limits are exceeded. In most instances, these limits are defined by whether a rational basis exists to conclude that legislation will bring about a rational result. The Legislature in the first instance, and the courts in the last instance, must ascertain whether such a rational basis exists. To label the court’s role as usurping that of the Legislature, see, e.g., post at (Cordy, J., dissenting), is to misunderstand the nature and purpose of judicial review. We owe great deference to the Legislature to decide social and policy issues, but it is the traditional and settled role of courts to decide constitutional issues. [FN31]

The history of constitutional law “is the story of the extension of constitutional rights and protections to people once ignored or excluded.” United States v. Virginia, 518 U.S. 515, 557 (1996) (construing equal protection clause of the Fourteenth Amendment to prohibit categorical exclusion of women from public military institute). This statement is as true in the area of civil marriage as in any other area of civil rights. See, e.g., Turner v. Safley, 482 U.S. 78 (1987); Loving v. Virginia, 388 U.S. 1 (1967); Perez v. Sharp, 32 Cal.2d 711 (1948). As a public institution and a right of fundamental importance, civil marriage is an evolving paradigm. The common law was exceptionally harsh toward women who became wives: a woman’s legal identity all but evaporated into that of her husband. See generally C.P. Kindregan, Jr., & M.L. Inker, Family Law and Practice §§ 1.9 and 1.10 (3d ed.2002). Thus, one early Nineteenth Century jurist could observe matter of factly that, prior to the abolition of slavery in Massachusetts, “the condition of a slave resembled the connection of a wife with her husband, and of infant children with their father. He is obliged to maintain them, and they cannot be separated from him.” Winchendon v. Hatfield, 4 Mass. 123, 129 (1808). But since at least the middle of the Nineteenth Century, both the courts and the Legislature have acted to ameliorate the harshness of the common-law regime. In Bradford v. Worcester, 184 Mass. 557, 562 (1904), we refused to apply the common-law rule that the wife’s legal residence was that of her husband to defeat her claim to a municipal “settlement of paupers.” In Lewis v. Lewis, 370 Mass. 619, 629 (1976), we abrogated the common-law doctrine immunizing a husband against certain suits because the common-law rule was predicated on “antediluvian assumptions concerning the role and status of women in marriage and in society.” Id. at 621. Alarms about the imminent erosion of the “natural” order of marriage were sounded over the demise of antimiscegenation laws, the expansion of the rights of married women, and the introduction of “no-fault” divorce. [FN32] Marriage has survived all of these transformations, and we have no doubt that marriage will continue to be a vibrant and revered institution.

We also reject the argument suggested by the department, and elaborated by some amici, that expanding the institution of civil marriage in Massachusetts to include same-sex couples will lead to interstate conflict. We would not presume to dictate how another State should respond to today’s decision. But neither should considerations of comity prevent us from according Massachusetts residents the full measure of protection available under the Massachusetts Constitution. The genius of our Federal system is that each State’s Constitution has vitality specific to its own traditions, and that, subject to the minimum requirements of the Fourteenth Amendment, each State is free to address difficult issues of individual liberty in the manner its own Constitution demands.

Several amici suggest that prohibiting marriage by same-sex couples reflects community consensus that homosexual conduct is immoral. Yet Massachusetts has a strong affirmative policy of preventing discrimination on the basis of sexual orientation. See G.L. c. 151B (employment, housing, credit, services); G.L. c. 265, § 39 (hate crimes); G.L. c. 272, § 98 (public accommodation); G.L. c. 76, § 5 (public education). See also, e.g., Commonwealth v. Balthazar, 366 Mass. 298 (1974) (decriminalization of private consensual adult conduct); Doe v. Doe, 16 Mass.App.Ct. 499, 503 (1983) (custody to homosexual parent not per se prohibited).

The department has had more than ample opportunity to articulate a constitutionally adequate justification for limiting civil marriage to opposite-sex unions. It has failed to do so. The department has offered purported justifications for the civil marriage restriction that are starkly at odds with the comprehensive network of vigorous, gender-neutral laws promoting stable families and the best interests of children. It has failed to identify any relevant characteristic that would justify shutting the door to civil marriage to a person who wishes to marry someone of the same sex.

The marriage ban works a deep and scarring hardship on a very real segment of the community for no rational reason. The absence of any reasonable relationship between, on the one hand, an absolute disqualification of same-sex couples who wish to enter into civil marriage and, on the other, protection of public health, safety, or general welfare, suggests that the marriage restriction is rooted in persistent prejudices against persons who are (or who are believed to be) homosexual. [FN33] “The Constitution cannot control such prejudices but neither can it tolerate them. Private biases may be outside the reach of the law, but the law cannot, directly or indirectly, give them effect.” Palmore v. Sidoti, 466 U.S. 429, 433 (1984) (construing Fourteenth Amendment). Limiting the protections, benefits, and obligations of civil marriage to opposite-sex couples violates the basic premises of individual liberty and equality under law protected by the Massachusetts Constitution.

IV

We consider next the plaintiffs’ request for relief. We preserve as much of the statute as may be preserved in the face of the successful constitutional challenge. See Mayor of Boston v. Treasurer & Receiver Gen., 384 Mass. 718, 725 (1981); Dalli v. Board of Educ., 358 Mass. 753, 759 (1971). See also G.L. c. 4, § 6, Eleventh.

Here, no one argues that striking down the marriage laws is an appropriate form of relief. Eliminating civil marriage would be wholly inconsistent with the Legislature’s deep commitment to fostering stable families and would dismantle a vital organizing principle of our society. [FN34] We face a problem similar to one that recently confronted the Court of Appeal for Ontario, the highest court of that Canadian province, when it considered the constitutionality of the same-sex marriage ban under Canada’s Federal Constitution, the Charter of Rights and Freedoms (Charter). See Halpern v. Toronto (City), 172 O.A.C. 276 (2003). Canada, like the United States, adopted the common law of England that civil marriage is “the voluntary union for life of one man and one woman, to the exclusion of all others.” Id. at, quoting Hyde v. Hyde, [1861-1873] All E.R. 175 (1866). In holding that the limitation of civil marriage to opposite- sex couples violated the Charter, the Court of Appeal refined the common-law meaning of marriage. We concur with this remedy, which is entirely consonant with established principles of jurisprudence empowering a court to refine a common-law principle in light of evolving constitutional standards. See Powers v. Wilkinson, 399 Mass. 650, 661-662 (1987) (reforming the common-law rule of construction of “issue”); Lewis v. Lewis, 370 Mass. 619, 629 (1976) (abolishing common-law rule of certain interspousal immunity).

We construe civil marriage to mean the voluntary union of two persons as spouses, to the exclusion of all others. This reformulation redresses the plaintiffs’ constitutional injury and furthers the aim of marriage to promote stable, exclusive relationships. It advances the two legitimate State interests the department has identified: providing a stable setting for child rearing and conserving State resources. It leaves intact the Legislature’s broad discretion to regulate marriage. See Commonwealth v. Stowell, 389 Mass. 171, 175 (1983).

In their complaint the plaintiffs request only a declaration that their exclusion and the exclusion of other qualified same-sex couples from access to civil marriage violates Massachusetts law. We declare that barring an individual from the protections, benefits, and obligations of civil marriage solely because that person would marry a person of the same sex violates the Massachusetts Constitution. We vacate the summary judgment for the department. We remand this case to the Superior Court for entry of judgment consistent with this opinion. Entry of judgment shall be stayed for 180 days to permit the Legislature to take such action as it may deem appropriate in light of this opinion. See, e.g., Michaud v. Sheriff of Essex County, 390 Mass. 523, 535-536 (1983).

So ordered.

GREANEY, J. (concurring).

I agree with the result reached by the court, the remedy ordered, and much of the reasoning in the court’s opinion. In my view, however, the case is more directly resolved using traditional equal protection analysis.

(a) Article 1 of the Declaration of Rights, as amended by art. 106 of the Amendments to the Massachusetts Constitution, provides:

“All people are born free and equal and have certain natural, essential and unalienable rights; among which may be reckoned the right of enjoying and defending their lives and liberties; that of acquiring, possessing and protecting property; in fine, that of seeking and obtaining their safety and happiness. Equality under the law shall not be denied or abridged because of sex, race, color, creed or national origin.”

This provision, even prior to its amendment, guaranteed to all people in the Commonwealth—equally—the enjoyment of rights that are deemed important or fundamental. The withholding of relief from the plaintiffs, who wish to marry, and are otherwise eligible to marry, on the ground that the couples are of the same gender, constitutes a categorical restriction of a fundamental right. The restriction creates a straightforward case of discrimination that disqualifies an entire group of our citizens and their families from participation in an institution of paramount legal and social importance. This is impermissible under art. 1.

Analysis begins with the indisputable premise that the deprivation suffered by the plaintiffs is no mere legal inconvenience. The right to marry is not a privilege conferred by the State, but a fundamental right that is protected against unwarranted State interference. See Zablocki v. Redhail, 434 U.S. 374, 384 (1978) (“the right to marry is of fundamental importance for all individuals”); Loving v. Virginia, 388 U.S. 1, 12 (1967) (freedom to marry is “one of the vital personal rights essential to the orderly pursuit of happiness by free men” under due process clause of Fourteenth Amendment); Skinner v. Oklahoma, 316 U.S. 535, 541 (1942) (marriage is one of “basic civil rights of man”). See also Turner v. Safley, 482 U.S. 78, 95-96 (1987) (prisoners’ right to marry is constitutionally protected). This right is essentially vitiated if one is denied the right to marry a person of one’s choice. See Zablocki v. Redhail, supra at 384 (all recent decisions of United States Supreme Court place “the decision to marry as among the personal decisions protected by the right of privacy”). [FN1]

Because our marriage statutes intend, and state, the ordinary understanding that marriage under our law consists only of a union between a man and a woman, they create a statutory classification based on the sex of the two people who wish to marry. See Baehr v. Lewin, 74 Haw. 530, 564 (1993) (plurality opinion) (Hawaii marriage statutes created sex-based classification); Baker v. State, 170 Vt. 194, 253 (1999) (Johnson, J., concurring in part and dissenting in part) (same). That the classification is sex based is self- evident. The marriage statutes prohibit some applicants, such as the plaintiffs, from obtaining a marriage license, and that prohibition is based solely on the applicants’ gender. As a factual matter, an individual’s choice of marital partner is constrained because of his or her own sex. Stated in particular terms, Hillary Goodridge cannot marry Julie Goodridge because she (Hillary) is a woman. Likewise, Gary Chalmers cannot marry Richard Linnell because he (Gary) is a man. Only their gender prevents Hillary and Gary from marrying their chosen partners under the present law. [FN2]

A classification may be gender based whether or not the challenged government action apportions benefits or burdens uniformly along gender lines. This is so because constitutional protections extend to individuals and not to categories of people. Thus, when an individual desires to marry, but cannot marry his or her chosen partner because of the traditional opposite-sex restriction, a violation of art. 1 has occurred. See Commonwealth v. Chou, 433 Mass. 229, 237-238 (2001) (assuming statute enforceable only across gender lines may offend Massachusetts equal rights amendment). I find it disingenuous, at best, to suggest that such an individual’s right to marry has not been burdened at all, because he or she remains free to chose another partner, who is of the opposite sex.

The equal protection infirmity at work here is strikingly similar to (although, perhaps, more subtle than) the invidious discrimination perpetuated by Virginia’s antimiscegenation laws and unveiled in the decision of Loving v. Virginia, supra. In its landmark decision striking down Virginia’s ban on marriages between Caucasians and members of any other race on both equal protection and substantive due process grounds, the United States Supreme Court soundly rejected the proposition that the equal application of the ban (i.e., that it applied equally to whites and blacks) made unnecessary the strict scrutiny analysis traditionally required of statutes drawing classifications according to race, see id. at 8-9, and concluded that “restricting the freedom to marry solely because of racial classifications violates the central meaning of the Equal Protection Clause.” Id. at 12. That our marriage laws, unlike antimiscegenation laws, were not enacted purposely to discriminate in no way neutralizes their present discriminatory character.

With these two propositions established (the infringement on a fundamental right and a sex-based classification), the enforcement of the marriage statutes as they are currently understood is forbidden by our Constitution unless the State can present a compelling purpose further by the statutes that can be accomplished in no other reasonable manner. [FN3] See Blixt v. Blixt, 437 Mass. 649, 655-656 (2002), cert. denied, 537 U.S. 1189 (2003); Lowell v. Kowalski, 380 Mass. 663, 667-669 (1980). This the State has not done. The justifications put forth by the State to sustain the statute’s exclusion of the plaintiffs are insufficient for the reasons explained by the court to which I add the following observations.

The rights of couples to have children, to adopt, and to be foster parents, regardless of sexual orientation and marital status, are firmly established. See E.N.O. v. L.M.M., 429 Mass. 824, 829, cert. denied, 528 U.S. 1005 (1999); Adoption of Tammy, 416 Mass. 205, 210-211 (1993). As recognized in the court’s opinion, and demonstrated by the record in this case, however, the State’s refusal to accord legal recognition to unions of same-sex couples has had the effect of creating a system in which children of same-sex couples are unable to partake of legal protections and social benefits taken for granted by children in families whose parents are of the opposite sex. The continued maintenance of this caste-like system is irreconcilable with, indeed, totally repugnant to, the State’s strong interest in the welfare of all children and its primary focus, in the context of family law where children are concerned, on “the best interests of the child.” The issue at stake is not one, as might ordinarily be the case, that can be unilaterally and totally deferred to the wisdom of the Legislature. “While the State retains wide latitude to decide the manner in which it will allocate benefits, it may not use criteria which discriminatorily burden the exercise of a fundamental right.” Moe v. Secretary of Admin. & Fin., 382 Mass. 629, 652 (1981). Nor can the State’s wish to conserve resources be accomplished by invidious distinctions between classes of citizens. See Plyler v. Doe, 457 U.S. 202, 216-217, 227 (1982). [FN4]

A comment is in order with respect to the insistence of some that marriage is, as a matter of definition, the legal union of a man and a woman. To define the institution of marriage by the characteristics of those to whom it always has been accessible, in order to justify the exclusion of those to whom it never has been accessible, is conclusory and bypasses the core question we are asked to decide. [FN5] This case calls for a higher level of legal analysis. Precisely, the case requires that we confront ingrained assumptions with respect to historically accepted roles of men and women within the institution of marriage and requires that we reexamine these assumptions in light of the unequivocal language of art. 1, in order to ensure that the governmental conduct challenged here conforms to the supreme charter of our Commonwealth. “A written constitution is the fundamental law for the government of a sovereign State. It is the final statement of the rights, privileges and obligations of the citizens and the ultimate grant of the powers and the conclusive definition of the limitations of the departments of State and of public officers.... To its provisions the conduct of all governmental affairs must conform. From its terms there is no appeal.” Loring v. Young, 239 Mass. 349, 376-377 (1921). I do not doubt the sincerity of deeply held moral or religious beliefs that make inconceivable to some the notion that any change in the common-law definition of what constitutes a legal civil marriage is now, or ever would be, warranted. But, as matter of constitutional law, neither the mantra of tradition, nor individual conviction, can justify the perpetuation of a hierarchy in which couples of the same sex and their families are deemed less worthy of social and legal recognition than couples of the opposite sex and their families. See Lawrence v. Texas, 123 S.Ct. 2472, 2486 (2003) (O’Connor, J., concurring) (moral disapproval, with no other valid State interest, cannot justify law that discriminates against groups of persons); Planned Parenthood of Southeastern Pa. v. Casey, 505 U.S. 833, 850 (1992) ( “Our obligation is to define the liberty of all, not to mandate our own moral code”).

(b) I am hopeful that our decision will be accepted by those thoughtful citizens who believe that same-sex unions should not be approved by the State. I am not referring here to acceptance in the sense of grudging acknowledgment of the court’s authority to adjudicate the matter. My hope is more liberating. The plaintiffs are members of our community, our neighbors, our coworkers, our friends. As pointed out by the court, their professions include investment advisor, computer engineer, teacher, therapist, and lawyer. The plaintiffs volunteer in our schools, worship beside us in our religious houses, and have children who play with our children, to mention just a few ordinary daily contacts. We share a common humanity and participate together in the social contract that is the foundation of our Commonwealth. Simple principles of decency dictate that we extend to the plaintiffs, and to their new status, full acceptance, tolerance, and respect. We should do so because it is the right thing to do. The union of two people contemplated by G.L. c. 207 “is a coming together for better or for worse, hopefully enduring, and intimate to the degree of being sacred. It is an association that promotes a way of life, not causes; a harmony in living, not political faiths; a bilateral loyalty, not commercial or social projects. Yet it is an association for as noble a purpose as any involved in our prior decisions.” Griswold v. Connecticut, 381 U.S. 479, 486 (1965). Because of the terms of art. 1, the plaintiffs will no longer be excluded from that association. [FN6]

SPINA, J. (dissenting, with whom Sosman and Cordy, JJ., join).

What is at stake in this case is not the unequal treatment of individuals or whether individual rights have been impermissibly burdened, but the power of the Legislature to effectuate social change without interference from the courts, pursuant to art. 30 of the Massachusetts Declaration of Rights. [FN1] The power to regulate marriage lies with the Legislature, not with the judiciary. See Commonwealth v. Stowell, 389 Mass. 171, 175 (1983). Today, the court has transformed its role as protector of individual rights into the role of creator of rights, and I respectfully dissent.

1. Equal protection. Although the court did not address the plaintiffs’ gender discrimination claim, G.L. c. 207 does not unconstitutionally discriminate on the basis of gender. [FN2] A claim of gender discrimination will lie where it is shown that differential treatment disadvantages one sex over the other. See Attorney Gen. v. Massachusetts Interscholastic Athletic Ass’n, 378 Mass. 342, 349-352 (1979). See also United States v. Virginia, 518 U.S. 515 (1996). General Laws c. 207 enumerates certain qualifications for obtaining a marriage license. It creates no distinction between the sexes, but applies to men and women in precisely the same way. It does not create any disadvantage identified with gender as both men and women are similarly limited to marrying a person of the opposite sex. See Commonwealth v. King, 374 Mass. 5, 15-22 (1977) (law prohibiting prostitution not discriminatory based on gender because of equal application to men and women).

Similarly, the marriage statutes do not discriminate on the basis of sexual orientation. As the court correctly recognizes, constitutional protections are extended to individuals, not couples. Ante n. 15. The marriage statutes do not disqualify individuals on the basis of sexual orientation from entering into marriage. All individuals, with certain exceptions not relevant here, are free to marry. Whether an individual chooses not to marry because of sexual orientation or any other reason should be of no concern to the court.

The court concludes, however, that G.L. c. 207 unconstitutionally discriminates against the individual plaintiffs because it denies them the “right to marry the person of one’s choice” where that person is of the same sex. Ante at. To reach this result the court relies on Loving v. Virginia, 388 U.S. 1, 12 (1967), and transforms “choice” into the essential element of the institution of marriage. The Loving case did not use the word “choice” in this manner, and it did not point to the result that the court reaches today. In Loving, the Supreme Court struck down as unconstitutional a statute that prohibited Caucasians from marrying non-Caucasians. It concluded that the statute was intended to preserve white supremacy and invidiously discriminated against non-Caucasians because of their race. See id. at 11-12. The “choice” to which the Supreme Court referred was the “choice to marry,” and it concluded that with respect to the institution of marriage, the State had no compelling interest in limiting the choice to marry along racial lines. Id. The Supreme Court did not imply the existence of a right to marry a person of the same sex. To the same effect is Perez v. Sharp, 32 Cal.2d 711 (1948), on which the court also relies.

Unlike the Loving and Sharp cases, the Massachusetts Legislature has erected no barrier to marriage that intentionally discriminates against anyone. Within the institution of marriage, [FN3] anyone is free to marry, with certain exceptions that are not challenged. In the absence of any discriminatory purpose, the State’s marriage statutes do not violate principles of equal protection. See Washington v. Davis, 426 U.S. 229, 240 (1976) ( “invidious quality of a law claimed to be ... discriminatory must ultimately be traced to a ... discriminatory purpose”); Dickerson v. Attorney Gen., 396 Mass. 740, 743 (1986) (for purpose of equal protection analysis, standard of review under State and Federal Constitutions is identical). See also Attorney Gen. v. Massachusetts Interscholastic Athletic Ass’n, supra. This court should not have invoked even the most deferential standard of review within equal protection analysis because no individual was denied access to the institution of marriage.

2. Due process. The marriage statutes do not impermissibly burden a right protected by our constitutional guarantee of due process implicit in art. 10 of our Declaration of Rights. There is no restriction on the right of any plaintiff to enter into marriage. Each is free to marry a willing person of the opposite sex. Cf. Zablocki v. Redhail, 434 U.S. 374 (1978) (fundamental right to marry impermissibly burdened by statute requiring court approval when subject to child support order).

Substantive due process protects individual rights against unwarranted government intrusion. See Aime v. Commonwealth, 414 Mass. 667, 673 (1993). The court states, as we have said on many occasions, that the Massachusetts Declaration of Rights may protect a right in ways that exceed the protection afforded by the Federal Constitution. Ante at. See Arizona v. Evans, 514 U.S. 1, 8 (1995) (State courts afforded broader protection of rights than granted by United States Constitution). However, today the court does not fashion a remedy that affords greater protection of a right. Instead, using the rubric of due process it has redefined marriage.

Although art. 10 may afford greater protection of rights than the due process clause of the Fourteenth Amendment, our treatment of due process challenges adheres to the same standards followed in Federal due process analysis. See Commonwealth v. Ellis, 429 Mass. 362, 371 (1999). When analyzing a claim that the State has impermissibly burdened an individual’s fundamental or other right or liberty interest, ”[w]e begin by sketching the contours of the right asserted. We then inquire whether the challenged restriction burdens that right.” Moe v. Secretary of Admin. & Fin., 382 Mass. 629, 646 (1981). Where a right deemed “fundamental” is implicated, the challenged restriction will be upheld only if it is “narrowly tailored to further a legitimate and compelling governmental interest.” Aime v. Commonwealth, supra at 673. To qualify as “fundamental” the asserted right must be “objectively, ‘deeply rooted in this Nation’s history and tradition,’ [Moore v. East Cleveland, 431 U.S. 494, 503 (1977) (plurality opinion) ] ... and ‘implicit in the concept of ordered liberty,’ such that ‘neither liberty nor justice would exist if they were sacrificed.’ ” Washington v. Glucksberg, 521 U.S. 702, 720-721 (1997), quoting Palko v. Connecticut, 302 U.S. 319, 325, 326 (1937) (right to assisted suicide does not fall within fundamental right to refuse medical treatment because novel and unsupported by tradition) (citations omitted). See Three Juveniles v. Commonwealth, 390 Mass. 357, 367 (1983) (O’Connor, J., dissenting), cert. denied sub nom. Keefe v. Massachusetts, 465 U.S. 1068 (1984). Rights that are not considered fundamental merit due process protection if they have been irrationally burdened. See Massachusetts Fed’n of Teachers v. Board of Educ., 436 Mass. 763, 777-779 & n. 14 (2002).

Although this court did not state that same-sex marriage is a fundamental right worthy of strict scrutiny protection, it nonetheless deemed it a constitutionally protected right by applying rational basis review. Before applying any level of constitutional analysis there must be a recognized right at stake. Same-sex marriage, or the “right to marry the person of one’s choice” as the court today defines that right, does not fall within the fundamental right to marry. Same-sex marriage is not “deeply rooted in this Nation’s history,” and the court does not suggest that it is. Except for the occasional isolated decision in recent years, see, e.g., Baker v. State, 170 Vt. 194 (1999), same-sex marriage is not a right, fundamental or otherwise, recognized in this country. Just one example of the Legislature’s refusal to recognize same-sex marriage can be found in a section of the legislation amending G.L. c. 151B to prohibit discrimination in the workplace on the basis of sexual orientation, which states: “Nothing in this act shall be construed so as to legitimize or validate a ‘homosexual marriage’....” St.1989, c. 516, § 19. In this Commonwealth and in this country, the roots of the institution of marriage are deeply set in history as a civil union between a single man and a single woman. There is no basis for the court to recognize same-sex marriage as a constitutionally protected right.

3. Remedy. The remedy that the court has fashioned both in the name of equal protection and due process exceeds the bounds of judicial restraint mandated by art. 30. The remedy that construes gender specific language as gender neutral amounts to a statutory revision that replaces the intent of the Legislature with that of the court. Article 30 permits the court to apply principles of equal protection and to modify statutory language only if legislative intent is preserved. See, e.g., Commonwealth v. Chou, 433 Mass. 229, 238-239 (2001) (judicial rewriting of gender language permissible only when Legislature intended to include both men and women). See also Lowell v. Kowalski, 380 Mass. 663, 670 (1980). Here, the alteration of the gender- specific language alters precisely what the Legislature unambiguously intended to preserve, the marital rights of single men and women. Such a dramatic change in social institutions must remain at the behest of the people through the democratic process.

Where the application of equal protection principles do not permit rewriting a statute in a manner that preserves the intent of the Legislature, we do not rewrite the statute. In Dalli v. Board of Educ., 358 Mass. 753 (1971), the court refused to rewrite a statute in a manner that would include unintended individuals. “To attempt to interpret this [statute] as including those in the category of the plaintiff would be to engage in a judicial enlargement of the clear statutory language beyond the limit of our judicial function. We have traditionally and consistently declined to trespass on legislative territory in deference to the time tested wisdom of the separation of powers as expressed in art. [30] of the Declaration of Rights of the Constitution of Massachusetts even when it appeared that a highly desirable and just result might thus be achieved.” Id. at 759. Recently, in Connors v. Boston, 430 Mass. 31 (1999), we refused to expand health insurance coverage to include domestic partners because such an expansion was within the province of the Legislature, where policy affecting family relationships is most appropriate and frequently considered. Id. at 42-43. Principles of equal protection do not permit the marriage statutes to be changed in the manner that we have seen today.

This court has previously exercised the judicial restraint mandated by art. 30 and declined to extend due process protection to rights not traditionally coveted, despite recognition of their social importance. See Tobin’s Case, 424 Mass. 250, 252-253 (1997) (receiving workers’ compensation benefits not fundamental right); Doe v. Superintendent of Schs. of Worcester, 421 Mass. 117, 129 (1995) (declaring education not fundamental right); Williams v. Secretary of the Executive Office of Human Servs., 414 Mass. 551, 565 (1993) (no fundamental right to receive mental health services); Matter of Tocci, 413 Mass. 542, 548 n. 4 (1992) (no fundamental right to practice law); Commonwealth v. Henry’s Drywall Co., 366 Mass. 539, 542 (1974) (no fundamental right to pursue one’s business). Courts have authority to recognize rights that are supported by the Constitution and history, but the power to create novel rights is reserved for the people through the democratic and legislative processes.

Likewise, the Supreme Court exercises restraint in the application of substantive due process ” ‘because guideposts for responsible decisionmaking in this unchartered area are scarce and open-ended.’ [Collins v. Harker Heights, 503 U.S. 115, 125 (1992).] By extending constitutional protection to an asserted right or liberty interest, we, to a great extent, place the matter outside the arena of public debate and legislative action. We must therefore ‘exercise the utmost care whenever we are asked to break new ground in this field,’ [id.], lest the liberty protected by the Due Process Clause be subtly transformed into the policy preferences of the Members of this Court, Moore [v. East Cleveland, 431 U.S. 494, 502 (1977) ] (plurality opinion).” Washington v. Glucksberg, supra at 720.

The court has extruded a new right from principles of substantive due process, and in doing so it has distorted the meaning and purpose of due process. The purpose of substantive due process is to protect existing rights, not to create new rights. Its aim is to thwart government intrusion, not invite it. The court asserts that the Massachusetts Declaration of Rights serves to guard against government intrusion into each individual’s sphere of privacy. Ante at. Similarly, the Supreme Court has called for increased due process protection when individual privacy and intimacy are threatened by unnecessary government imposition. See, e.g., Lawrence v. Texas, 123 S.Ct. 2472 (2003) (private nature of sexual behavior implicates increased due process protection); Eisenstadt v. Baird, 405 U.S. 438 (1972) (privacy protection extended to procreation decisions within nonmarital context); Griswold v. Connecticut, 381 U.S. 479 (1965) (due process invoked because of intimate nature of procreation decisions). These cases, along with the Moe case, focus on the threat to privacy when government seeks to regulate the most intimate activity behind bedroom doors. The statute in question does not seek to regulate intimate activity within an intimate relationship, but merely gives formal recognition to a particular marriage. The State has respected the private lives of the plaintiffs, and has done nothing to intrude in the relationships that each of the plaintiff couples enjoy. Cf. Lawrence v. Texas, supra at 2484 (case “does not involve whether the government must give formal recognition to any relationship that homosexual persons seek to enter”). Ironically, by extending the marriage laws to same-sex couples the court has turned substantive due process on its head and used it to interject government into the plaintiffs’ lives.

SOSMAN, J. (dissenting, with whom Spina and Cordy, JJ., join).

In applying the rational basis test to any challenged statutory scheme, the issue is not whether the Legislature’s rationale behind that scheme is persuasive to us, but only whether it satisfies a minimal threshold of rationality. Today, rather than apply that test, the court announces that, because it is persuaded that there are no differences between same-sex and opposite-sex couples, the Legislature has no rational basis for treating them differently with respect to the granting of marriage licenses. [FN1] Reduced to its essence, the court’s opinion concludes that, because same-sex couples are now raising children, and withholding the benefits of civil marriage from their union makes it harder for them to raise those children, the State must therefore provide the benefits of civil marriage to same-sex couples just as it does to opposite-sex couples. Of course, many people are raising children outside the confines of traditional marriage, and, by definition, those children are being deprived of the various benefits that would flow if they were being raised in a household with married parents. That does not mean that the Legislature must accord the full benefits of marital status on every household raising children. Rather, the Legislature need only have some rational basis for concluding that, at present, those alternate family structures have not yet been conclusively shown to be the equivalent of the marital family structure that has established itself as a successful one over a period of centuries. People are of course at liberty to raise their children in various family structures, as long as they are not literally harming their children by doing so. See Blixt v. Blixt, 437 Mass. 649, 668-670 (2002) (Sosman, J., dissenting), cert. denied, 537 U.S. 1189 (2003). That does not mean that the State is required to provide identical forms of encouragement, endorsement, and support to all of the infinite variety of household structures that a free society permits.

Based on our own philosophy of child rearing, and on our observations of the children being raised by same-sex couples to whom we are personally close, we may be of the view that what matters to children is not the gender, or sexual orientation, or even the number of the adults who raise them, but rather whether those adults provide the children with a nurturing, stable, safe, consistent, and supportive environment in which to mature. Same-sex couples can provide their children with the requisite nurturing, stable, safe, consistent, and supportive environment in which to mature, just as opposite-sex couples do. It is therefore understandable that the court might view the traditional definition of marriage as an unnecessary anachronism, rooted in historical prejudices that modern society has in large measure rejected and biological limitations that modern science has overcome.

It is not, however, our assessment that matters. Conspicuously absent from the court’s opinion today is any acknowledgment that the attempts at scientific study of the ramifications of raising children in same-sex couple households are themselves in their infancy and have so far produced inconclusive and conflicting results. Notwithstanding our belief that gender and sexual orientation of parents should not matter to the success of the child rearing venture, studies to date reveal that there are still some observable differences between children raised by opposite-sex couples and children raised by same-sex couples. See post at—(Cordy, J., dissenting). Interpretation of the data gathered by those studies then becomes clouded by the personal and political beliefs of the investigators, both as to whether the differences identified are positive or negative, and as to the untested explanations of what might account for those differences. (This is hardly the first time in history that the ostensible steel of the scientific method has melted and buckled under the intense heat of political and religious passions.) Even in the absence of bias or political agenda behind the various studies of children raised by same-sex couples, the most neutral and strict application of scientific principles to this field would be constrained by the limited period of observation that has been available. Gay and lesbian couples living together openly, and official recognition of them as their children’s sole parents, comprise a very recent phenomenon, and the recency of that phenomenon has not yet permitted any study of how those children fare as adults and at best minimal study of how they fare during their adolescent years. The Legislature can rationally view the state of the scientific evidence as unsettled on the critical question it now faces: Are families headed by same- sex parents equally successful in rearing children from infancy to adulthood as families headed by parents of opposite sexes? Our belief that children raised by same-sex couples should fare the same as children raised in traditional families is just that: a passionately held but utterly untested belief. The Legislature is not required to share that belief but may, as the creator of the institution of civil marriage, wish to see the proof before making a fundamental alteration to that institution.

Although ostensibly applying the rational basis test to the civil marriage statutes, it is abundantly apparent that the court is in fact applying some undefined stricter standard to assess the constitutionality of the marriage statutes’ exclusion of same-sex couples. While avoiding any express conclusion as to any of the proffered routes by which that exclusion would be subjected to a test of strict scrutiny—infringement of a fundamental right, discrimination based on gender, or discrimination against gays and lesbians as a suspect classification—the opinion repeatedly alludes to those concepts in a prolonged and eloquent prelude before articulating its view that the exclusion lacks even a rational basis. See, e.g., ante at (noting that State Constitution is “more protective of individual liberty and equality,” demands “broader protection for fundamental rights,” and is “less tolerant of government intrusion into the protected spheres of private life” than Federal Constitution); ante at (describing decision to marry and choice of marital partner as “among life’s momentous acts of self-definition”); ante at— (repeated references to “right to marry” as “fundamental”); ante at— (repeated comparisons to statutes prohibiting interracial marriage, which were predicated on suspect classification of race); ante at—(characterizing ban on same-sex marriage as “invidious” discrimination that “deprives individuals of access to an institution of fundamental legal, personal, and social significance” and again noting that Massachusetts Constitution “protects matters of personal liberty against government incursion” more zealously than Federal Constitution); ante at (characterizing “whom to marry, how to express sexual intimacy, and whether and how to establish a family” as “among the most basic of every individual’s liberty and due process rights”); ante at (“liberty interest in choosing whether and whom to marry would be hollow” if Commonwealth could “foreclose an individual from freely choosing the person” to marry); ante at (opining that in “overlapping realms of personal autonomy, marriage, family life and child-rearing,” characterized as “fundamentally private areas of life,” court uses “integrated” analysis instead of “narrow focus”). See also ante at n. 29 (suggesting that prohibition on same-sex marriage “impose[s] limits on personal beliefs”); ante at n. 31] (suggesting that “total deference” to Legislature in this case would be equivalent to “strip[ping]” judiciary “of its constitutional authority to decide challenges” in such areas as forced sterilization, antimiscegenation statutes, and abortion, even though all cited examples pertain to fundamental rights analyzed under strict scrutiny, not under rational basis test); ante at (civil marriage as “a right of fundamental importance”); ante at (noting State policy of “preventing discrimination on the basis of sexual orientation”); ante at, (prohibition against same-sex marriage inconsistent with “gender neutral laws promoting stable families,” and “rooted in persistent prejudices against” homosexuals); ante at (prohibition against same-sex marriage “violated the basic premises of individual liberty”). In short, while claiming to apply a mere rational basis test, the court’s opinion works up an enormous head of steam by repeated invocations of avenues by which to subject the statute to strict scrutiny, apparently hoping that that head of steam will generate momentum sufficient to propel the opinion across the yawning chasm of the very deferential rational basis test.

Shorn of these emotion-laden invocations, the opinion ultimately opines that the Legislature is acting irrationally when it grants benefits to a proven successful family structure while denying the same benefits to a recent, perhaps promising, but essentially untested alternate family structure. Placed in a more neutral context, the court would never find any irrationality in such an approach. For example, if the issue were government subsidies and tax benefits promoting use of an established technology for energy efficient heating, the court would find no equal protection or due process violation in the Legislature’s decision not to grant the same benefits to an inventor or manufacturer of some new, alternative technology who did not yet have sufficient data to prove that that new technology was just as good as the established technology. That the early results from preliminary testing of the new technology might look very promising, or that the theoretical underpinnings of the new technology might appear flawless, would not make it irrational for the Legislature to grant subsidies and tax breaks to the established technology and deny them to the still unproved newcomer in the field. While programs that affect families and children register higher on our emotional scale than programs affecting energy efficiency, our standards for what is or is not “rational” should not be bent by those emotional tugs. Where, as here, there is no ground for applying strict scrutiny, the emotionally compelling nature of the subject matter should not affect the manner in which we apply the rational basis test.

Or, to the extent that the court is going to invoke such emotion-laden and value-laden rhetoric as a means of heightening the degree of scrutiny to be applied, the same form of rhetoric can be employed to justify the Legislature’s proceeding with extreme caution in this area. In considering whether the Legislature has a rational reason for postponing a dramatic change to the definition of marriage, it is surely pertinent to the inquiry to recognize that this proffered change affects not just a load-bearing wall of our social structure but the very cornerstone of that structure. See post at—(Cordy, J., dissenting). Before making a fundamental alteration to that cornerstone, it is eminently rational for the Legislature to require a high degree of certainty as to the precise consequences of that alteration, to make sure that it can be done safely, without either temporary or lasting damage to the structural integrity of the entire edifice. The court today blithely assumes that there are no such dangers and that it is safe to proceed (see ante at—, an assumption that is not supported by anything more than the court’s blind faith that it is so.

More importantly, it is not our confidence in the lack of adverse consequences that is at issue, or even whether that confidence is justifiable. The issue is whether it is rational to reserve judgment on whether this change can be made at this time without damaging the institution of marriage or adversely affecting the critical role it has played in our society. Absent consensus on the issue (which obviously does not exist), or unanimity amongst scientists studying the issue (which also does not exist), or a more prolonged period of observation of this new family structure (which has not yet been possible), it is rational for the Legislature to postpone any redefinition of marriage that would include same-sex couples until such time as it is certain that that redefinition will not have unintended and undesirable social consequences. Through the political process, the people may decide when the benefits of extending civil marriage to same-sex couples have been shown to outweigh whatever risks—be they palpable or ephemeral—are involved. However minimal the risks of that redefinition of marriage may seem to us from our vantage point, it is not up to us to decide what risks society must run, and it is inappropriate for us to abrogate that power to ourselves merely because we are confident that “it is the right thing to do.” Ante at (Greaney, J., concurring).

As a matter of social history, today’s opinion may represent a great turning point that many will hail as a tremendous step toward a more just society. As a matter of constitutional jurisprudence, however, the case stands as an aberration. To reach the result it does, the court has tortured the rational basis test beyond recognition. I fully appreciate the strength of the temptation to find this particular law unconstitutional—there is much to be said for the argument that excluding gay and lesbian couples from the benefits of civil marriage is cruelly unfair and hopelessly outdated; the inability to marry has a profound impact on the personal lives of committed gay and lesbian couples (and their children) to whom we are personally close (our friends, neighbors, family members, classmates, and co-workers); and our resolution of this issue takes place under the intense glare of national and international publicity. Speaking metaphorically, these factors have combined to turn the case before us into a “perfect storm” of a constitutional question. In my view, however, such factors make it all the more imperative that we adhere precisely and scrupulously to the established guideposts of our constitutional jurisprudence, a jurisprudence that makes the rational basis test an extremely deferential one that focuses on the rationality, not the persuasiveness, of the potential justifications for the classifications in the legislative scheme. I trust that, once this particular “storm” clears, we will return to the rational basis test as it has always been understood and applied. Applying that deferential test in the manner it is customarily applied, the exclusion of gay and lesbian couples from the institution of civil marriage passes constitutional muster. I respectfully dissent.

CORDY, J. (dissenting, with whom Spina and Sosman, JJ., join).

The court’s opinion concludes that the Department of Public Health has failed to identify any “constitutionally adequate reason” for limiting civil marriage to opposite-sex unions, and that there is no “reasonable relationship” between a disqualification of same-sex couples who wish to enter into a civil marriage and the protection of public health, safety, or general welfare. Consequently, it holds that the marriage statute cannot withstand scrutiny under the Massachusetts Constitution. Because I find these conclusions to be unsupportable in light of the nature of the rights and regulations at issue, the presumption of constitutional validity and significant deference afforded to legislative enactments, and the “undesirability of the judiciary substituting its notions of correct policy for that of a popularly elected Legislature” responsible for making such policy, Zayre Corp. v. Attorney Gen., 372 Mass. 423, 433 (1977), I respectfully dissent. Although it may be desirable for many reasons to extend to same-sex couples the benefits and burdens of civil marriage (and the plaintiffs have made a powerfully reasoned case for that extension), that decision must be made by the Legislature, not the court.

If a statute either impairs the exercise of a fundamental right protected by the due process or liberty provisions of our State Constitution, or discriminates based on a constitutionally suspect classification such as sex, it will be subject to strict scrutiny when its validity is challenged. See Blixt v. Blixt, 437 Mass. 649, 655-656, 660-661 (2002), cert. denied, 537 U.S. 1189 (2003) (fundamental right); Lowell v. Kowalski, 380 Mass. 663, 666 (1980) (sex-based classification). If it does neither, a statute “will be upheld if it is ‘rationally related to a legitimate State purpose.’ ” Hallett v. Wrentham, 398 Mass. 550, 557 (1986), quoting Paro v. Longwood Hosp., 373 Mass. 645, 649 (1977). This test, referred to in State and Federal constitutional jurisprudence as the “rational basis test,” [FN1] is virtually identical in substance and effect to the test applied to a law promulgated under the State’s broad police powers (pursuant to which the marriage statutes and most other licensing and regulatory laws are enacted): that is, the law is valid if it is reasonably related to the protection of public health, safety, or general welfare. See, e.g., Leigh v. Board of Registration in Nursing, 395 Mass. 670, 682-683 (1985) (applying rational basis review to question of State exercise of police power).

The Massachusetts marriage statute does not impair the exercise of a recognized fundamental right, or discriminate on the basis of sex in violation of the equal rights amendment to the Massachusetts Constitution. Consequently, it is subject to review only to determine whether it satisfies the rational basis test. Because a conceivable rational basis exists upon which the Legislature could conclude that the marriage statute furthers the legitimate State purpose of ensuring, promoting, and supporting an optimal social structure for the bearing and raising of children, it is a valid exercise of the State’s police power.

A. Limiting marriage to the union of one man and one woman does not impair the exercise of a fundamental right. Civil marriage is an institution created by the State. In Massachusetts, the marriage statutes are derived from English common law, see Commonwealth v. Knowlton, 2 Mass. 530, 534 (1807), and were first enacted in colonial times. Commonwealth v. Munson, 127 Mass. 459, 460 (1879). They were enacted to secure public interests and not for religious purposes or to promote personal interests or aspirations. (See discussion infra at—). As the court notes in its opinion, the institution of marriage is “the legal union of a man and woman as husband and wife,” ante at, and it has always been so under Massachusetts law, colonial or otherwise.

The plaintiffs contend that because the right to choose to marry is a “fundamental” right, the right to marry the person of one’s choice, including a member of the same sex, must also be a “fundamental” right. While the court stops short of deciding that the right to marry someone of the same sex is “fundamental” such that strict scrutiny must be applied to any statute that impairs it, it nevertheless agrees with the plaintiffs that the right to choose to marry is of fundamental importance (“among the most basic” of every person’s “liberty and due process rights”) and would be “hollow” if an individual was foreclosed from “freely choosing the person with whom to share ... the ... institution of civil marriage.” Ante at. Hence, it concludes that a marriage license cannot be denied to an individual who wishes to marry someone of the same sex. In reaching this result the court has transmuted the “right” to marry into a right to change the institution of marriage itself. This feat of reasoning succeeds only if one accepts the proposition that the definition of the institution of marriage as a union between a man and a woman is merely “conclusory” (as suggested, ante at [Greaney, J., concurring] ), rather than the basis on which the “right” to partake in it has been deemed to be of fundamental importance. In other words, only by assuming that “marriage” includes the union of two persons of the same sex does the court conclude that restricting marriage to opposite-sex couples infringes on the “right” of same-sex couples of “marry.” [FN2]

The plaintiffs ground their contention that they have a fundamental right to marry a person of the same sex in a long line of Supreme Court decisions, e.g., Turner v. Safley, 482 U.S. 78 (1987); Zablocki v. Redhail, 434 U.S. 374 (1978); Loving v. Virginia, 388 U.S. 1 (1967); Griswold v. Connecticut, 381 U.S. 479 (1965); Skinner v. Oklahoma, 316 U.S. 535 (1942); that discuss the importance of marriage. In context, all of these decisions and their discussions are about the “fundamental” nature of the institution of marriage as it has existed and been understood in this country, not as the court has redefined it today. Even in that context, its “fundamental” nature is derivative of the nature of the interests that underlie or are associated with it. [FN3] An examination of those interests reveals that they are either not shared by same-sex couples or not implicated by the marriage statutes.

Supreme Court cases that have described marriage or the right to marry as “fundamental” have focused primarily on the underlying interest of every individual in procreation, which, historically, could only legally occur within the construct of marriage because sexual intercourse outside of marriage was a criminal act. [FN4] In Skinner v. Oklahoma, supra, the first case to characterize marriage as a “fundamental” right, the Supreme Court stated, as its rationale for striking down a sterilization statute, that ”[m]arriage and procreation are fundamental to the very existence of the race.” Id. at 541. In concluding that a sterilized individual “is forever deprived of a basic liberty,” id., the Court was obviously referring to procreation rather than marriage, as this court recognized in Matter of Moe, 385 Mass. 555, 560 (1982). Similarly, in Loving v. Virginia, supra, in which the United States Supreme Court struck down Virginia’s antimiscegenation statute, the Court implicitly linked marriage with procreation in describing marriage as “fundamental to our very existence.” Id. at 12. In Zablocki v. Redhail, supra, the Court expressly linked the right to marry with the right to procreate, concluding that “if [the plaintiff’s] right to procreate means anything at all, it must imply some right to enter the only relationship in which the State ... allows sexual relations legally to take place.” Id. at 386. Once again, in Turner v. Safley, supra, striking a State regulation that curtailed the right of an inmate to marry, the Court included among the important attributes of such marriages the “expectation that [the marriage] ultimately will be fully consummated.” Id. at 96. See Milford v. Worcester, 7 Mass. 48, 52 (1810) (purpose of marriage is “to regulate, chasten, and refine, the intercourse between the sexes; and to multiply [and] preserve ... the species”). Because same-sex couples are unable to procreate on their own, any right to marriage they may possess cannot be based on their interest in procreation, which has been essential to the Supreme Court’s denomination of the right to marry as fundamental.

Supreme Court cases recognizing a right to privacy in intimate decision-making, e.g., Griswold v. Connecticut, supra (striking down statute prohibiting use of contraceptives); Roe v. Wade, 410 U.S. 113 (1973) (striking down statute criminalizing abortion), have also focused primarily on sexual relations and the decision whether or not to procreate, and have refused to recognize an “unlimited right” to privacy. Id. at 154. Massachusetts courts have been no more willing than the Federal courts to adopt a “universal[ ]” “privacy doctrine,” Marcoux v. Attorney Gen., 375 Mass. 63, 67 (1978), or to derive “controversial ‘new’ rights from the Constitution.” Aime v. Commonwealth, 414 Mass. 667, 674 n. 10 (1993).

What the Griswold Court found “repulsive to the notions of privacy surrounding the marriage relationship” was the prospect of “allow[ing] the police to search the sacred precincts of marital bedrooms for telltale signs of the use of contraceptives.” Griswold v. Connecticut, supra at 485-486. See Moe v. Secretary of Admin. & Fin., 382 Mass. 629, 658 (1981), quoting L. Tribe, American Constitutional Law 924 (1978) (finding it “difficult to imagine a clearer case of bodily intrusion” than being forced to bear a child). When Justice Goldberg spoke of “marital relations” in the context of finding it “difficult to imagine what is more private or more intimate than a husband and wife’s marital relations[hip],” Griswold v. Connecticut, supra at 495 (Goldberg, J., concurring), he was obviously referring to sexual relations. [FN5] Similarly, in Lawrence v. Texas, 123 S.Ct. 2472 (2003), it was the criminalization of private sexual behavior that the Court found violative of the petitioners’ liberty interest.

In Massachusetts jurisprudence, protected decisions generally have been limited to those concerning “whether or not to beget or bear a child,” Matter of Moe, 385 Mass. 555, 564 (1982) (see Opinion of the Justices, 423 Mass. 1201, 1234-1235 [1996] [“focus of (the Griswold and Roe cases) and the cases following them has been the intrusion ... into the especially intimate aspects of a person’s life implicated in procreation and childbearing”] ); how to raise a child, see Care & Protection of Robert, 408 Mass. 52, 58, 60 (1990); or whether or not to accept medical treatment, see Brophy v. New England Sinai Hosp., Inc., 398 Mass. 417, 430 (1986); Superintendent of Belchertown State Sch. v. Saikewicz, 373 Mass. 728, 742 (1977), none of which is at issue here. See also Commonwealth v. Balthazar, 366 Mass. 298, 301 (1974) (statute punishing unnatural and lascivious acts does not apply to sexual conduct engaged in by adults in private, in light of “articulation of the constitutional right of an individual to be free from government regulation of certain sex related activities”).

The marriage statute, which regulates only the act of obtaining a marriage license, does not implicate privacy in the sense that it has found constitutional protection under Massachusetts and Federal law. Cf. Commonwealth v. King, 374 Mass. 5, 14 (1977) (solicitation of prostitution “while in a place to which the public had access” implicated no “constitutionally protected rights of privacy”); Marcoux v. Attorney Gen., supra at 68 (right to privacy, at most, protects conduct “limited more or less to the hearth”). It does not intrude on any right that the plaintiffs have to privacy in their choices regarding procreation, an intimate partner or sexual relations. [FN6] The plaintiffs’ right to privacy in such matters does not require that the State officially endorse their choices in order for the right to be constitutionally vindicated.

Although some of the privacy cases also speak in terms of personal autonomy, no court has ever recognized such an open-ended right. “That many of the rights and liberties protected by the Due Process Clause sound in personal autonomy does not warrant the sweeping conclusion that any and all important, intimate, and personal decisions are so protected....” Washington v. Glucksberg, 521 U.S. 702, 727 (1997). Such decisions are protected not because they are important, intimate, and personal, but because the right or liberty at stake is “so deeply rooted in our history and traditions, or so fundamental to our concept of constitutionally ordered liberty” that it is protected by due process. Id. Accordingly, the Supreme Court has concluded that while the decision to refuse unwanted medical treatment is fundamental, Cruzan v. Director, Mo. Dep’t of Health, 497 U.S. 261, 278 (1990), because it is deeply rooted in our nation’s history and tradition, the equally personal and profound decision to commit suicide is not because of the absence of such roots. Washington v. Glucksberg, supra.

While the institution of marriage is deeply rooted in the history and traditions of our country and our State, the right to marry someone of the same sex is not. No matter how personal or intimate a decision to marry someone of the same sex might be, the right to make it is not guaranteed by the right of personal autonomy.

The protected right to freedom of association, in the sense of freedom of choice “to enter into and maintain certain intimate human relationships,” Roberts v. United States Jaycees, 468 U.S. 609, 617 (1984) (as an element of liberty or due process rather than free speech), is similarly limited and unimpaired by the marriage statute. As recognized by the Supreme Court, that right affords protection only to “certain kinds of highly personal relationships,” id. at 618, such as those between husband and wife, parent and child, and among close relatives, id. at 619, that “have played a critical role in the culture and traditions of the Nation,” id. at 618-619, and are “deeply rooted in this Nation’s history and tradition.” Moore v. East Cleveland, 431 U.S. 494, 498-499, 503 (1977) (distinguishing on this basis between family and nonfamily relationships). Unlike opposite-sex marriages, which have deep historic roots, or the parent-child relationship, which reflects a “strong tradition” founded on “the history and culture of Western civilization” and “is now established beyond debate as an enduring American tradition,” Wisconsin v. Yoder, 406 U.S. 205, 232 (1972); or extended family relationships, which have been “honored throughout our history,” Moore v. East Cleveland, supra at 505, same-sex relationships, although becoming more accepted, are certainly not so “deeply rooted in this Nation’s history and tradition” as to warrant such enhanced constitutional protection.

Although “expressions of emotional support and public commitment” have been recognized as among the attributes of marriage, which, ”[t]aken together ... form a constitutionally protected marital relationship” (emphasis added), Turner v. Safley, 482 U.S. 78, 95, 96 (1987), those interests, standing alone, are not the source of a fundamental right to marry. While damage to one’s “status in the community” may be sufficient harm to
