It's facially a California Public Records Act case. One you might otherwise ignore.
But you care. Deeply.
The Court of Appeal holds that bills -- e.g., invoices -- are protected by the attorney-client privilege in California.
That's different than the federal common law rule. The Ninth Circuit has held that the amount of the fee (among other things) isn't privileged. So too have some other states.
Not so in California. At least as of today.
