Every trial court order holding that Proposition 64 applied retroactively is now invalid under California's prinicples of stare decisis, because the 1st Dist. Court of Appeal has issued an opinion holding that it does not.
This is consistent with a string of California Supreme Court cases going back years and including ones as recent as November. Not a surprise to me (as you may have read), but expect shock-and-awe "updates" from the panic marketing firms tomorrow.
