California Code, Penal Code - PEN § 2676

(a) Any person, or his or her attorney, guardian, or conservator may file a petition with the superior court of the county in which he or she is confined for an order to prohibit the administration upon him or her of an organic therapy.  The filing of such a petition shall constitute a refusal of consent or withdrawal of any prior consent to an organic therapy.  The clerk of the court shall serve a copy of the petition, on the same day it is filed, upon the warden.

(b) The warden shall file a response to the petition to prohibit the enforced administration of any organic therapy.  The response shall be filed no later than 10 days after the filing of the petition, unless the court grants a continuance not to exceed 10 additional days, and shall be personally served upon the person and served upon his or her attorney, guardian, or conservator on the same day as it is filed with the clerk of the superior court.  The response shall not constitute a petition for an order to proceed with any organic therapy pursuant to Section 2675, which shall be the exclusive procedure for authorization to administer any organic therapy.
