(a) The denial of licensure, suspension, restriction of license, or voluntary surrender following the initiation of disciplinary action by another state or other government agency, of a license, registration, permit, or certificate to practice as a health care professional shall constitute grounds for denial of a permit or license or for disciplinary action against a licensee. A certified copy of the finding from another state which establishes an act which if committed in California would be grounds for discipline shall be conclusive evidence of that action.

(b) The denial of licensure, suspension, restriction of license, or voluntary surrender following the initiation of disciplinary action by another California health care professional licensing board shall constitute grounds for denial of a permit or license or for disciplinary action against a licensee. A certified copy of the decision or judgment shall be conclusive evidence of that action.
