(2) Upon petition of a person committed to a state hospital, or the guardian, relative or creditor of the person or other interested person, the court of competent jurisdiction in the county in which the state hospital is located or, if the petitioner requests a hearing in the county where the commitment originated, then the court in such county shall hold a hearing to determine whether or not the person in the state hospital is competent. A guardian who is not the petitioner shall be notified of the hearing at least three days before the date set for hearing. After the hearing the court shall enter an order pursuant to its finding and serve a copy of the order on the petitioner and forward a copy of the order to the committing court.

(3) When a person committed to a state hospital has been declared incompetent pursuant to subsection (2) of this section and is discharged from the hospital, the superintendent of the hospital shall advise the court which entered the order of incompetency whether or not, in the opinion of the chief medical officer of the hospital on the basis of medical evidence, the person is competent. The superintendent shall make a reasonable effort to notify the discharged person of the advice to the court. If the court is advised that the person is competent, the court shall enter an order to that effect. If the court is advised that the person is not competent, upon petition of the person, the guardian, relative or creditor of the person or other interested person, the court shall hold a hearing to determine whether or not the discharged person is competent. The court shall serve a copy of any order entered pursuant to this subsection on the person and forward a copy of such order to the committing court.
