Well hopefully they won’t dog around and will look at the phones before it can get to an appeal.
I’m curious about the civil suit anyway. In California, the suit is customarily brought where the DEFENDANT resides, not the plaintiff. My guess is there will be a venue transfer motion back to San Francisco.
In any event, the Santa Clara judge has no authority to strike down a search warrant issued in a San Francisco criminal case. Plus, in a civil suit, the defendants can simply seek the contents of the cell phones through discovery and seen sanctions if the plaintiffs destroy the evidence.
