A federal appeals court on Monday set aside its decision striking down Indiana's ban on gay marriage until the U.S. Supreme Court weighs in on the matter.

In an unanimous September 4 ruling, the Seventh Circuit Court of Appeals in Chicago knocked down similar prohibitions in Wisconsin and Indiana, finding each to be unconstitutional.

Both states have appealed the ruling to the Supreme Court, which is expected to consider petitions stemming from challenges to bans in five states, including Utah, Virginia, Oklahoma, Indiana and Wisconsin, at a September 29 closed-door conference.

Justices could agree to hear one or several cases, deny all of them, or choose to set the requests aside for now.

The move comes just days after a federal judge ordered Indiana officials to recognize the out-of-state marriage of a lesbian couple, of which one of the partners is terminally ill. It is the second time the state has been forced to make an exception.
