If a commitment hearing has been scheduled pursuant to subdivision 3 of subsection C of § 16.1-339, the petition for judicial approval filed by the facility under subsection C of § 16.1-339 shall serve as the petition for involuntary commitment as long as such petition complies in substance with the provisions of this subsection.
If the petition is not dismissed or withdrawn, copies of the petition, together with a notice of the hearing, shall be served immediately upon the minor and the minor's parents, if they are not petitioners, by the sheriffs of the jurisdictions in which the minor and his parents are located. The hearing on the petition may proceed if the court determines that copies of the petition and notice of the hearing have been served on at least one parent and a reasonable effort has been made to serve such copies on both parents. No later than 24 hours before the hearing, the court shall appoint a guardian ad litem for the minor and counsel to represent the minor, unless it has determined that the minor has retained counsel. Upon the request of the minor's counsel, for good cause shown, and after notice to the petitioner and all other persons receiving notice of the hearing, the court may continue the hearing once for a period not to exceed 96 hours.
Any recommendation made by a state mental health facility or state hospital regarding the minor's involuntary commitment may be admissible during the course of the hearing.
