South Carolina on Tuesday asked a federal appeals court to put a case challenging the state's ban on gay marriage on hold pending review of a similar case by the Supreme Court.

Gay and lesbian couples began marrying in South Carolina last month after a federal judge declared the state's ban unconstitutional. The Fourth Circuit Court of Appeals and the Supreme Court denied state requests to put the ruling on hold as an appeal is pursued.

South Carolina Attorney General Alan Wilson on Tuesday asked the Fourth Circuit to put the case on hold until the Supreme Court decides whether to review a similar challenge to Michigan's ban.

The Cincinnati, Ohio-based Sixth Court of Appeals upheld Michigan's ban, along with similar bans from Ohio, Kentucky and Tennessee.

Michigan's case is the only one out of the four which received a full trial, making it the frontrunner for Supreme Court review. Plaintiffs in a case challenging Louisiana's ban have also asked the justices for review.

“If the Supreme court grants the DeBoer petitions, that Court may reach a decision applicable nationally regarding the constitutionality of same-sex marriage bans,” Wilson wrote in his filing. “[T]he Attorney General respectfully requests that this Court stay or continue the appeal in this case, including briefing, until such time as the Supreme court makes a final decision regarding the DeBoer petitions and any petition in the instant case.”

If the court decides to proceed with the case, Wilson asked for a full court review, skipping the customary 3-judge panel.
