Business and Professions Code section 2878.8

The board may deny any application or may suspend or revoke any license issued under this chapter based upon the denial of licensure, suspension, restriction, or other disciplinary action of a license by another state, any other government agency, or by another California health care professional licensing board. A certified copy of the finding shall be conclusive evidence of that action provided that, if from another state, the findings establish an act which if committed in California would be grounds for discipline.
