California Code, Business and Professions Code - BPC § 18646

(a) This chapter applies to all amateur boxing, wrestling, and full contact martial arts contests.

(b) The commission may, however, authorize one or more nonprofit boxing, wrestling, or martial arts clubs, organizations, or sanctioning bodies, upon approval of its bylaws, to administer its rules for amateur boxing, wrestling, and full contact martial arts contests, and may, therefore, waive direct commission application of laws and rules, including licensure, subject to the commission's affirmative finding that the standards and enforcement of similar rules by a club, organization, or sanctioning body meet or exceed the safety and fairness standards of the commission.  The commission shall review the performance of any such club, organization, or sanctioning body annually.

(c) Every contest subject to this section shall be preceded by a physical examination, specified by the commission, of every contestant.  A physician and surgeon shall be in attendance at the contest.  There shall be a medical insurance program satisfactory to the commission provided by an amateur club, organization, or sanctioning body in effect covering all contestants.  The commission shall review compliance with these requirements.

(d) Any club, organization, or sanctioning body that conducts, holds, or gives amateur contests pursuant to this section, which collects money for the event, shall furnish a written financial report of receipts and disbursements within 90 days of the event.

(e) The commission has the right to have present without charge or restriction such representatives as are necessary to obtain compliance with this section.

(f) The commission may require any additional notices and reports it deems necessary to enforce the provisions of this section.

(g) The commission, at its discretion, may rescind previously approved authorization of a nonprofit boxing, wrestling, or martial arts club, organization, or sanctioning body to administer its rules for amateur boxing, wrestling, and full contact martial arts contests.
