I really do think that holdings like this one, were they left to stand, would essentially spell the death of consumer class actions in California.
It sufficiently conflicts -- as the opinion itself expressly recognizes -- with plethora of other Court of Appeal opinions that the California Supreme Court should either (1) accept review of the thing, or (2) depublish it.
Because to let something like this stand, in my view, would make justice in California substantially worse.
