The New Mexico Supreme Court heard oral argument today on whether that state's laws would allow same-sex marriage, the Associated Press reports. New Mexico is the rare state that does not explicitly authorize or bar same-sex marriage. While "the marriage laws — unchanged since 1961 — include a marriage license application with sections for male and female applicants" and references husbands-and-wives, at least one judge also has ruled denying marriage licenses to same-sex couples is unconstitutional, the AP also reports.
