Opponents of gay marriage on Friday asked the California Supreme Court to reinstate Proposition 8.

According to the Los Angeles Times, Protect Marriage, the group that sponsored the 2008 constitutional amendment which defined marriage as a heterosexual union, argued that Democratic Governor Jerry Brown did not have the authority to end enforcement of Proposition 8.

Proposition 8 tumbled after the Supreme Court ruled that interveners lacked standing to defend the law, leaving in place a 2010 circuit court ruling declaring it unconstitutional.

Within days after the Supreme Court ruled, the Ninth Circuit Court of Appeals lifted its stay in the ruling, allowing same-sex marriages to resume in California.

However, Protect Marriage argues that a provision in the California Constitution prohibits state officials from refusing to enforce a law unless it has been deemed unconstitutional by an appellate court.

In its filing, Protect Marriage argued that unless the court acts, “the end result will be to allow one federal district judge – empowered by state officials who openly advocated for and ceded to Proposition 8's demise – to nullify a constitutional initiative approved by more than seven million voters.”

Protect Marriage added that retired Chief U.S. District Judge Vaughn R. Walker's ruling only applies to the two counties where plaintiffs live, not the entire state.

UC Davis law professor Vikram Amar told the paper that the California Supreme Court was likely to “stay out of this and say the scope of Judge Walker's order is a matter for the federal courts to determine.”
