Celebrating the Prop 8 ruling? Not so fast. The Supremes didn't rule on Prop 8 at all, just that Prop 8 supporters didn't have legal standing to challenge the lower court's ruling against 8. And since Governor Jerry Brown and Attorney General Kamala Harris don't like Prop 8 and refused to defend it, there's no one to take the case to court.
In fact, the ruling undermines the California initiative process by allowing the Governor and Attorney General to refuse to defend anything they don't like. How about Prop 13? Legal professors are already saying this opens a door to kill it. Somebody sues against Prop 13 in federal court, Brown and Harris refuse to defend it, et voilà, game over!
Gay marriage advocates deserved their day in court. They probably would have gotten Prop 8 ruled unconstitutional. They didn't get it. This was a trick by Brown and Harris that backfired, and a punt by the Supremes.
