A lawsuit challenging New York's same-sex marriage law can continue, a New York state supreme court justice ruled Tuesday.

The judge said it's possible that the state violated its open meeting law when it legalized same-sex marriage last year.

Justice Robert Wiggins has agreed to hear the case argued by New Yorkers for Constitutional Freedoms, a Christian lobbying group.

The state had asked Wiggins to dismiss the case.

However, Wiggins said a trial is warranted to examine closed door gatherings before the vote that may have violated the open meeting law.

New York became the sixth state to allow same-sex marriage in July.
