Imperial County officials have renewed their effort to defend California's gay marriage ban, Proposition 8, in court, the AP reported.

The effort comes a month after an appeals court ruled the county could not intervene as a defendant in the first federal case to question the constitutionality of a gay marriage ban.

The Ninth Circuit Court of Appeals has asked the California Supreme Court to decide whether the law's sponsors, ProtectMarriage.com, have the legal standing to defend it in court, but the court dismissed the county's request.

At the time, the county's head elections clerk declined to join the suit. But armed with a newly elected clerk, the county filed new paperwork on Friday to rejoin the proceedings.

Proposition 8 backers believe the county's inclusion is critical because top state officials have refused to defend the law in court. Former Republican Governor Arnold Schwarzenegger and Democratic Governor Jerry Brown, as attorney general, called the law indefensible.

On Wednesday, lawyers for the plaintiffs asked the appeals court to allow the weddings of gay and lesbian couples to resume.
