California Code, Probate Code - PROB § 1964

An order of the court authorizing a conservator to consent to sterilization which is upheld on appeal automatically expires in one year from the final determination on appeal unless earlier terminated by the court. A conservatorship established for the sole purpose of authorizing a conservator to consent to sterilization under this chapter shall automatically terminate upon completion of the sterilization procedure or upon expiration of the court's order authorizing the conservator to consent to sterilization, whichever occurs first. If, upon the expiration of the court's order under this chapter, the person named as conservator determines that the conservatorship is still required for the purpose of this chapter, he or she may petition the court for reappointment as conservator for a succeeding six-month period upon a showing of good cause as to why any sterilization authorized by the court has not been completed.
