— COLORADO: A state judge struck down the state's gay marriage ban July 9 but put the ruling on hold pending the outcome of a state appeal. Despite that order, several county clerks began issuing marriage licenses to same-sex couples. Colorado's Republican attorney general, John Struthers, who is appealing has said he knows it's only a matter of time until gay marriage is legal there, but that he'll continue to defend the law. All documents in the case must be turned over by Oct. 20.

— WISCONSIN: A federal judge in Madison struck down the state's ban in June, leading to more than 500 same-sex marriages in the state before the judge put her ruling on hold.

The court will hear arguments late this month.
