I think at this point everyone is looking for someone, probably a judge, to block it, so as to be able to heap imprecations on his head while breathing private sighs of relief.
They want a plausible scapegoat, a sin-eater.
My sincerest hope is that any judge it goes before passes it back to the legislature saying, “It is not the responsibility of the judicial system to govern on behalf of the legislature. It is the responsibility of the politicians to govern judiciously and the court will leave this legislation where it belongs, to the Californian government.”
