The NY Times has this report on a challenge in the U.S. Supreme Court to state laws prohibiting sodomy. Virginia likewise has criminalized sodomy, fornication, and lewd cohabitation. The most recent signs from the Virginia Supreme Court, oddly enough, are that some or all would uphold the constitutionality of these statutes. Justice Kinser cited them in her concurring opinion in the Arlington County "domestic partner" benefits case (in MS Word) from 2000. The majority cited the fornication and cohabitation statutes as the basis for the wrongful discharge claim in Mitchem v. Counts (in MS Word), also decided in 2000.
The viability of these criminal statutes is an element in a recurring issue in domestic relations cases, where one party may assert the constitutional privilege against self-incrimination to questions about sex acts other than with his or her spouse. The Virginia Court of Appeals' unpublished Goldmann case is one example of the self-incrimination issue.
Judge Merhige held that the fornication and cohabitation statutes were unconstitutional in Doe v. Duling, 603 F. Supp. 960 (E.D. Va. 1985), but this opinion was vacated on appeal for lack of standing, 782 F.2d 1202 (4th Cir. 1986), in an opinion by Judge Wilkinson. Roanoke gay rights lawyers also lost a constitutional challenge for lack of standing in the Virginia Court of Appeals, as reported in this 2000 opinion.
