(From the San Francisco Chronicle)
"The city of San Francisco asked a judge Thursday for permission to intervene in the federal lawsuit challenging California's ban on same-sex marriage, a request that may intensify the battle for control of the high-stakes litigation.
The leader of an organization that filed the suit against Proposition 8 has already accused established gay-rights groups of trying to undermine the case and promised to oppose their attempt to intervene. San Francisco raised the stakes Thursday by filing a similar motion with Chief U.S. District Judge Vaughn Walker, who has scheduled a hearing for Aug. 19.
The city would add "a unique local government perspective" to the case, along with its extensive legal experience in defending gay and lesbian rights, if allowed to intervene, City Attorney Dennis Herrera's office said in court papers."
