[JURIST] Two Russian men have unsuccessfully tried to register for a marriage certificate in Moscow in an effort to provide legal grounds to challenge the Russian family code [text, in Russian]. Next week, regional MP Edvard Murzin, who says he is not gay but is trying to promote gay rights, and magazine editor Ed Mishin will receive an official written rejection, which they will use to challenge Russia's marriage law in the Russian Constitutional Court [official website]. According to Mishin, "the Russian constitution [text] does not say that people of the same sex cannot get married. It says in black-and-white that sex-, race- or religion-based discrimination is banned." BBC News has more. From Russia, MosNews has local coverage.
