California Code, Penal Code - PEN § 2675

(a) If the proposed organic therapy is not prohibited by subdivision (a) or (b) of Section 2670.5, then in order to administer the therapy the warden of the institution in which the person is confined shall petition the superior court of the county in which the person is confined for an order authorizing such organic therapy.

(b) The petition shall summarize the facts which the attending physician is required to communicate to the person pursuant to Section 2673, and shall state whether the person has the capacity for informed consent, and, if so, whether the person has given his or her informed consent to the proposed therapy.  The petition shall clearly specify what organic therapy the institution proposes to administer to the person.  The petition shall specify what mental illness, disorder, abnormality, or defect justifies the administration of such therapy.  Copies of the petition 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.

(c) The person confined, or his or her attorney, guardian, or conservator may file a response to the petition for organic therapy.  The response shall be filed no later than 10 days after service of the petition unless the court grants a continuance not to exceed 10 additional days, and shall be served on the warden on the same day it is filed.
