A federal appeals court will hear arguments in a case challenging Michigan's ban on gay marriage on Wednesday, August 6.

The Sixth Circuit Court of Appeals in Cincinnati announced the hearing date on Friday, ABC affiliate WXYZ reported.

After holding a 2-week trial in Detroit, U.S. District Judge Bernard Friedman ruled the state's marriage ban invalid on March 21. Clerks in four Michigan counties opened their doors the following day, a Saturday, to marry more than 300 gay couples before the Sixth Circuit Court of Appeals suspended Friedman's decision as the state pursues an appeal.

Plaintiffs in the case are Jayne Rowse and April DeBoer, who wish to marry so they may jointly adopt the three children they are raising together but were forced to adopt individually.

All four states under the Sixth Circuit's jurisdiction – Kentucky, Michigan, Ohio and Tennessee – have appealed similar rulings to the appeals court.
