California: Claim that Filner backer filed petition to try and kill recall effort

More catastrophes in the San Diego recall law, as a Filner backer allegedly filed a recall petition to start the clock on the recall. Looking at the San Diego law, it seems that he has a decent claim. You may remember that a Scott Walker supporter filed a petition a week before anyone else, but that was simply to start the clock running for fundraising. I don't know if other jurisdictions have a provision that allows one petition to preempt others.
