The Sixth Circuit Court of Appeals in Cincinnati on Monday announced it would hear arguments in cases challenging gay marriage bans in the four states in its geographic area on August 6.

The court said in its order that the same three-judge panel will hear all four cases, SCOTUS blog reported.

Arguments will be limited to 30 minutes for each side in cases challenging bans in Michigan and Ohio. Less time, 15 minutes per side, will be allowed in cases challenging bans in Kentucky and Tennessee.

Of the four cases, only the one challenging Michigan's ban asks the court to strike down the state's entire ban and allow gay couples to marry. The other three cases involve recognition of the out-of-state marriages of gay couples.

Lawsuits challenging all 31 state bans followed last year's U.S. Supreme Court ruling striking down a key provision of the Defense of Marriage Act (DOMA), which led to federal recognition of the marriages of gay couples. Cases challenging bans in Virginia (Fourth Circuit), Utah and Oklahoma (both in the Tenth Circuit) have been heard by federal appellate court judges.
