OPINION OF THE COURT
Plaintiffs contend that the NY Constitution requires defendant State of New York to permit same-sex couples to marry.
The Legislature has placed many parameters on marriage in New York (see e.g. Domestic Relations Law §§ 5, 6, 7). Historically, the role of defining the boundaries of marriage “ ‘has always been subject to the control of the Legislature’ ” (Fearon v Treanor,
Courts use great caution when urged to recognize a new fundamental right or significantly expand an established one. The compelling reason for such caution was explained by the United States Supreme Court as follows:
“[W]e ha[ve] always been reluctant to expand the concept of substantive due process because guideposts for responsible decisionmaking in this unchartered area are scarce and open-ended. 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, lest the liberty protected by the Due Process*14 Clause be subtly transformed into the policy preferences of the Members of this Court” (Washington v Glucksberg,521 US 702 , 720 [1997] [internal quotation marks and citations omitted]).
One of the primary safeguards in maintaining a cautious and principled substantive due process analysis is the requirement that an asserted right or liberty generally be “ ‘deeply rooted in this Nation’s history and tradition’ ” (id. at 721, quoting Moore v East Cleveland,
Plaintiffs seek to bring the right to marry the person of their choosing regardless of gender within the protection of the well-recognized fundamental right to marry (see Zablocki v Redhail,
“Long ago . . . the Court characterized marriage as*15 the most important relation in life and as the foundation of the family and of society, without which there would be neither civilization nor progress . . . [T]he Court recognized that the right to marry, establish a home and bring up children is a central part of the liberty protected by the Due Process Clause . . . and . . . marriage was described as fundamental to the very existence and survival of the race” (id. at 384 [internal quotation marks and citations omitted]).
In a similar vein, the Court of Appeals has observed about marriage: “However much this relationship may be debased at times it nevertheless is the foundation upon which must rest the perpetuation of society and civilization” (Mirizio v Mirizio,
To remove from “marriage” a definitional component of that institution (i.e., one woman, one man) which long predates the constitutions of this country and State (see e.g. Griswold v Connecticut,
The NY Constitution’s Equal Protection Clause provides, in pertinent part, that “[n]o person shall be denied the equal
As to the level of scrutiny regarding assertions of sexual orientation discrimination, we recently held, in Matter of Valentine v American Airlines (
“Courts, including the United States Supreme Court, have applied the rational basis standard, rather than strict or heightened scrutiny, when reviewing sexual orientation discrimination allegations (see Romer v Evans,517 US 620 , 631-633 [1996]; Lofton v Secretary of Dept, of Children & Family Servs.,358 F3d 804 , 818 [11th Cir 2004], cert denied [543] US [1081] [2005]; Schroeder v Hamilton School Dist.,282 F3d 946 , 950-951 [7th Cir 2002], cert denied537 US 974 [2002]; Under 21, Catholic Home Bur. for Dependent Children v City*17 of New York, [supra at 364] [noting that courts have uniformly refused to apply higher level of scrutiny to sexual orientation discrimination]; Matter of Cooper,187 AD2d 128 , 133 [1993], supra-, Matter of Shields v Madigan, [5 Mise 3d 901, 907 (2004)] [determining that rational basis existed for state law permitting only opposite-sex couples to marry]).”
The doctrine of adhering to precedent is an important one (see Baker v Lorillard,
Nor are we persuaded by plaintiffs’ contention that the Domestic Relations Law discriminates on the basis of gender. In Valentine, we addressed an analogous assertion about the Workers’ Compensation Law and held that, since that law
“is facially neutral and applies equally to males and females, we do not accept claimant’s argument that [the statute] discriminates on the basis of gender (see Baker v State, 170 Vt 194, 215 n 13,744 A2d 864 , 880 n 13 [1999], and cases cited therein; Matter of Shields v Madigan, [supra at 906]; but see Baehr v Lewin, 74 Haw 530, 572,852 P2d 44 , 64 [1993] [based on state constitution])” (Matter of Valentine v American Airlines, supra at 41).
The same reasoning applies to the facially neutral Domestic Relations Law. Hence, the marriage laws will survive plaintiffs’ equal protection claims—as well as their due process claims— unless they are unsupported by a rational basis.
“When reviewing using a rational basis standard, £a classification must be upheld ... if there is any reasonably conceiv
The interests urged as meeting the low threshold of a rational basis include, among others: preserving the historic legal and cultural understanding of marriage; recognizing heterosexual marriage as a social institution in which procreation occurs; and conforming with the current legal landscape nationwide. Certainly, the logic of each of these grounds is neither flawless nor finely tailored; however, it need not be. “[W]here rationality is the test, a State ‘does not violate the Equal Protection Clause merely because the classification made by its laws are imperfect’ ” (Massachusetts Bd. of Retirement v Murgia,
We consider first the preservation of the historic legal and cultural understanding of marriage. In Lawrence v Texas (
While history and the collective wisdom of our ancestors should not be lightly set aside (see Elk Grove Unified School
Here, after the recent efforts to redefine marriage received considerable publicity and some judicial support, the United States Congress passed, and President Clinton signed into law, the federal Defense of Marriage Act (see 1 USC § 7; 28 USC § 1738C), and nearly all state legislatures that have addressed the issue have similarly maintained the traditional definition of marriage (over 40 states have reportedly enacted statutes similar to the federal Defense of Marriage Act and many have amended their constitutions). In light of the recent statement of Justice O’Connor in Lawrence v Texas (
However, as previously stated, the test here is rational basis, where “distinctions may be made with substantially less than mathematical exactitude, and rationality is not impaired because a distinction is either over-inclusive or under-inclusive” (Port Chester Nursing Home v Axelrod,
“[t]he State could reasonably decide that by encouraging opposite-sex couples to marry, thereby assuming legal and financial obligations, the children born from such relationships will have better opportunities to be nurtured and raised by two parents within long-term, committed relationships, which society has traditionally viewed as advantageous for children” (Standhardt v Superior Ct. ex rel. County of Maricopa, supra at 287-288; see Hernandez v Robles, supra at 104, 105).
Stated another way:
“One of the State’s key interests in supporting opposite-sex marriage is not necessarily to encourage and promote ‘natural’ procreation across the board and at the expense of other forms of becoming parents, such as by adoption and assisted reproduction; rather, it encourages opposite-sex couples who, by definition, are the only type of*21 couples that can reproduce on their own by engaging in sex with little or no contemplation of the consequences that might result, i.e. a child, to procreate responsibly . . . The institution of opposite-sex marriage both encourages such couples to enter into a stable relationship before having children and to remain in such a relationship if children arrive during the marriage unexpectedly” (Morrison v Sadler,821 NE2d 15 , 25 [Ind 2005]; see Hernandez v Robles, supra at 123-124 [concurring op]).10
While the parties and amici have cited numerous studies by a host of authors and purported authorities, some of which affirm the premise of this rationale and some of which dispute it, the Legislature is the better forum for sorting through this type of conflicting data on an important social issue. We agree with the opinion of the First Department (see Hernandez v Robles, supra; see also Langan v St. Vincent’s Hosp. of N.Y.,
Cardona, P.J., Mercure, Carpinello and Mugglin, JJ., concur.
Ordered that the order is affirmed, without costs.
Notes
. We note at the outset that several appellate courts in other jurisdictions have addressed a similar issue under their constitutions and, in some instances, the US Constitution. They have arrived at varying conclusions, often by divided votes (see e.g. Lewis v Harris, 378 NJ Super 168,
. Although the facts relevant to the legal issues are succinct, we acknowledge the personal accounts of their various backgrounds that plaintiffs have set forth in the record. We do not question the sincerity of these accounts. However, a detailed recitation of plaintiffs’ personal accounts in this decision is not necessary to address the legal issues before us.
. “Just as judges should not shrink from carrying out the legislative will, so too should they not shrink from declaring statutes unconstitutional in proper cases, however distasteful that may be” (People v LaValle,
. This language is similar to US Constitution, 14th Amendment, § 1, which states that “[n]o State shall . . . deprive any person of life, liberty, or property, without due process of law.”
. With regard to the US Constitution, rights not specifically set forth in the Bill of Rights, but found to be fundamental to the “liberty” element of due process, include those
“to marry, Loving v. Virginia,388 U.S. 1 (1967); to have children, Skinner v. Oklahoma ex rel. Williamson,316 U.S. 535 (1942); to direct the education and upbringing of one’s children, Meyer v. Nebraska,262 U.S. 390 (1923); Pierce v. Society of Sisters,268 U.S. 510 (1925); to marital privacy, Griswold v. Connecticut,381 U.S. 479 (1965); to use contraception, ibid.; Eisenstadt v. Baird,405 U.S. 438 (1972); to bodily integrity, Rochin v. California,342 U.S. 165 (1952), and to abortion [Planned Parenthood of Southeastern Pa. v] Casey, [505 US 833 (1992)]” (Washington v Glucksberg,521 US 702 , 720 [1397]).
. In Griswold v Connecticut (supra at 486), the United States Supreme Court stated that “[w]e deal with a right of privacy older than the Bill of Rights—older than our political parties, older than our school system. Marriage is a coming together for better or for worse, hopefully enduring, and intimate to the degree of being sacred.” Since Griswold spoke of marriage within the context of restrictions on contraceptives, it is apparent that the Court was referring to opposite-sex marriage (id. at 482 [“This law . . . operates directly on an intimate relation of husband and wife”]).
. This is not to suggest that all aspects of marriage have or must remain mired in an inflexible mold. The legal rights of the parties to the relationship have changed (see e.g. People v Liberta,
. The Equal Protection Clause of the US Constitution 14th Amendment states that no state shall “deny to any person within its jurisdiction the equal protection of the laws.”
. Plaintiffs urge that in this case, New York’s Equal Protection Clause should be interpreted more expansively than its federal counterpart. However, departure from such clear Court of Appeals’ precedent must be left to that Court.

. We note that an appeal of a lower court decision finding no due process or equal protection violation in the one woman, one man element of marriage was dismissed for want of substantial federal question by the United States Supreme Court in Baker v Nelson (291 Minn 310,
. The freedom of speech provision of the NY Constitution provides: “Every citizen may freely speak, write and publish his or her sentiments on all subjects, being responsible for the abuse of that right; and no law shall be passed to restrain or abridge the liberty of speech or of the press” (NY Const, art I, § 8).
. In such regard, we note that gays and lesbians in New York have, in recent years, advocated and successfully obtained passage of a broad array of rights from the Legislature (see e.g. Civil Rights Law § 40-c [2]; Education Law § 313; Executive Law § 296; Insurance Law § 2701 [a]; Penal Law § 240.30 [3]; L 2002, chs 73, 467, 468).
