New York's top court has declined to hear an appeal from a Monroe County-based group that sought to overturn the state's law allowing same-sex marriage.

The state Court of Appeals announced its decision Tuesday.

New Yorkers for Constitutional Freedoms, a conservative group opposed to same-sex unions, filed a lawsuit against the state Senate last year, claiming that Republicans in the chamber had violated the state's Open Meetings Law when discussing gay marriage. In particular, the group took issue with a closed-door session held in 2011 with New York City Mayor Michael Bloomberg, the Senate GOP's top financial backer and a supporter of same-sex couples.
