Cal. INS § 557

It is a misdemeanor for any person alone or in concert to prepare or make any bid or other writing which falsely purports to be a bona fide offer to repair a damaged motor vehicle or any other damaged property, with the intent that the same be used for the purpose of fraudulently leading an automobile liability insurer to believe: (a) That a bid of some other person represents an offer made in open competition; or (b) That the policy provisions of such insurer governing bids for the repair of vehicles or other property insured under the policy have been complied with in good faith.
