A federal judge has ordered Ohio authorities to recognize the marriages of gay couples performed in other states.
Judge Timothy Black's ruling on Monday criticized the state's "ongoing arbitrary discrimination on the basis of sexual orientation."
He says the state's marriage recognition bans are unconstitutional and unenforceable.
Black's order doesn't force Ohio to allow gay marriages to be performed in the state.
The state plans to appeal Black's ruling, arguing that Ohio has a sovereign right to ban gay marriage, which voters did overwhelmingly in 2004.
Black delayed deciding whether to stay his ruling pending appeal until attorneys on both sides present their arguments on the issue by the end of Tuesday.
