BOOOOOOM!!!
Indeed, there is a decision of the United States Supreme Court, binding on all other courts and public officials, that a state law restricting marriage to opposite-sex couples does NOT violate the federal Constitution's guarantees of equal protection and due process of law. After the Minnesota Supreme Court held that Minnesota laws preventing marriages between persons of 279*279 the same sex did not violate the equal protection or due process clauses of the United States Constitution (Baker v. Nelson (1971) 291 Minn. 310, 191 N.W.2d 185), the decision was appealed to the United States Supreme Court, as federal law then permitted (see 28 U.S.C. former § 1257(2), 62 Stat. 929 as amended by 84 Stat. 590). The high court later dismissed that appeal "for want of substantial federal question." (Baker v. Nelson (1972) 409 U.S. 810, 93 S.Ct. 37, 34 L.Ed.2d 65.)
As the United States Supreme Court has explained, a dismissal on the ground that an appeal presents no substantial federal question is a decision on the merits of the case, establishing that the lower court's decision on the issues of federal law was correct. (Mandel v. Bradley (1977) 432 U.S. 173, 176, 97 S.Ct. 2238, 53 L.Ed.2d 199; Hicks v. Miranda (1975) 422 U.S. 332, 344, 95 S.Ct. 2281, 45 L.Ed.2d 223.) Summary decisions of this kind "prevent lower courts from coming to opposite conclusions on the precise issues presented and necessarily decided by those actions." (Mandel v. Bradley, supra, at p. 176, 97 S.Ct. 2238.) Thus, the high court's summary decision in Baker v. Nelson, supra, 409 U.S. 810, 93 S.Ct. 37, 34 L.Ed.2d 65, prevents lower courts and public officials from coming to the conclusion that a state law barring marriage between persons of the same sex violates the equal protection or due process guarantees of the United States Constitution.
