When any conservatee challenges his or her placement or conditions of confinement pursuant to Section 1473 of the Penal Code or Section 7250 of the Welfare and Institutions Code, notwithstanding the continuing jurisdiction of the court which appointed the conservators, judicial review shall be in the county where the conservatorship was established or in the county in which the conservatee is placed or confined. If the conservatee is released as a result of the hearing, he or she shall be returned to the county where the conservatorship originated.
