Resuming gay marriage "is consistent with Californias [sic] long history of treating all people and their relationships with equal dignity and respect," Schwarzenegger said in his legal filing.
Walker ruled Wednesday the ban violates federal equal protections and due process laws.
However, he agreed to block gay marriages from immediately resuming until he can consider arguments on whether to keep the ban in effect while its supporters take their appeal to the 9th U.S. Circuit Court of Appeals.
Brown, a candidate for governor, said that ruling means it's time for gays to begin marrying again. "While there is still the potential for limited administrative burdens should future marriages of same-sex couples be later declared invalid, these potential burdens are outweighed by this court's conclusion, based on the overwhelming evidence, that Proposition 8 is unconstitutional," Brown said in his legal filing.
It was unclear when Walker would issue a ruling on the possible resumption of same-sex marriages.
