CA Bus & Prof Code Section 4990.38

The board may deny an application or may suspend or revoke a license or registration issued under the chapters it administers and enforces for any disciplinary action imposed by this state or another state or territory or possession of the United States, or by a governmental agency on a license, certificate or registration to practice marriage and family therapy, clinical social work, educational psychology, professional clinical counseling, or any other healing art. The disciplinary action, which may include denial of licensure or revocation or suspension of the license or imposition of restrictions on it, constitutes unprofessional conduct. A certified copy of the disciplinary action decision or judgment shall be conclusive evidence of that action.
