Ten states have united in support of California's gay marriage ban, Proposition 8.

An August ruling that declared the ban unconstitutional is being appealed to the Ninth Circuit Court of Appeals by its sponsor, ProtectMarriage.com, a coalition of social conservative groups that includes the Church of Jesus Christ of Latter-day Saints (the Mormons), the California Catholic Conference and various evangelical churches.

The brief, filed on Friday, says the federal court “exceeded its judicial authority” in ruling against the gay marriage ban, the Casper Star-Tribune reported.

“If public affirmation of anyone and everyone's personal love and commitment is the single purpose of marriage, a limitless number of rights claims could be set up that evacuate the term marriage of any meaning,” the brief says.

The amicus brief also says that states, not the federal courts, have final say in deciding whether to recognize the unions of gay and lesbian couples with marriage.

Proposition 8 was approved by a narrow majority of Californians in 2008. Passage put an end to the gay weddings taking place in the state after the California Supreme Court legalized the institution.

The case of Perry vs. Schwarzenegger is the first to challenge the constitutionality of a gay marriage ban. Plaintiffs – a gay couple and a lesbian couple who wish to marry – are being represented by the American Foundation for Equal Rights (AFER), a group formed to support the case. A recent New York City fundraiser hosted by former RNC Chair Ken Mehlman netted $1.2 million for the case.

The states listed in the brief are Alabama, Wyoming, Florida, Idaho, Indiana, Louisiana, Michigan, South Carolina, Utah and Virginia. None of which allow gay couples to marry.
