Lawyers challenging the constitutionality of California's gay marriage ban, Proposition 8, on Wednesday asked a federal appeals court to allow the weddings to resume, the AP reported.

Last year, U.S. District Judge Vaughn Walker ruled the 2008 voter-approved law unconstitutional.

Supporters of the ban, however, appealed the decision and the Ninth Circuit Court of Appeals placed Walker's ruling on hold.

The appeals court heard oral arguments in the case in December, but then turned to the California Supreme Court to decide whether the law's sponsors have the legal standing to defend it in court. The high court has said it won't hear arguments in the case until September.

“Each day plaintiffs, and gay men and lesbians like them, are denied the right to marry – denied the full blessings of citizenship – is a day that never can be returned to them,” lawyers for the plaintiffs argued in their filing.

The lawyers also noted President Barack Obama's recent decision to no longer defend the Defense of Marriage Act (DOMA), the 1996 law that bans the federal government from recognizing the legal marriages of gay and lesbian couples, and allows states to ignore such marriages.
