A federal appeals court on Monday denied Michigan's request for an en banc review of a lower court's ruling declaring the state's ban on gay marriage unconstitutional.

Michigan Attorney General Bill Schuette asked the court for a full 15-judge review of the case. Most cases are first appealed to a 3-judge panel. But Schuette argued that removing the step would quicken the appeals process and save the state money.

In a unanimous decision, the Sixth Circuit Court of Appeals in Cincinnati denied the state's request.

U.S. District Judge Bernard Friedman's March 21 ruling declaring the marriage ban invalid, lead to clerks in four Michigan counties marrying more than 300 gay couples on the following day, a Saturday, before the appeals court suspended Friedman's decision as the state pursues an appeal.

While the federal government has said it will recognize the marriages as valid, Governor Rick Snyder said the state will not. The ACLU filed a lawsuit seeking to force Michigan to recognize the marriages.

The ACLU is also suing Utah for not recognizing more than 1,300 gay couples who married after the state's ban was struck down in December.
