Section 14-6-426 - Initial appearance; adjudicatory hearing; entry of decree and disposition; evidentiary matters; continuance of disposition hearing(a) At their initial hearing, which may be held after a detention or shelter care hearing, the child and his parents, guardian or custodian shall be advised by the court of their rights under law and as provided in this act. They shall also be advised of the specific allegations in the petition and the child shall be given an opportunity to admit or deny them. They shall also be advised of the possible liability for costs of treatment or services pursuant to this act. It is not necessary at the initial appearance for the district attorney to establish probable cause to believe the allegations in the petition are true. When a detention or shelter care hearing is held in accordance with W.S. 14-6-409, a separate initial hearing is not required if the child and his parents, guardian or custodian were present at the detention or shelter care hearing and advised by the court as provided in this subsection.(b) If the allegations of the petition are denied, the court may, with consent of the parties, proceed immediately to hear evidence on the petition or it may set a later time not to exceed sixty (60) days for an adjudicatory hearing, unless the court finds good cause to delay or postpone the hearing. In no case shall the court hold the adjudicatory hearing more than ninety (90) days after the date the petition is filed. Only competent, relevant and material evidence shall be admissible at an adjudicatory hearing to determine the truth of the allegations in the petition. If after an adjudicatory hearing the court finds that the allegations in the petition are not established as required by this act, it shall dismiss the petition and order the child released from any detention or shelter care.(c) If after an adjudicatory hearing or a valid admission or confession the court or jury finds that a child is in need of supervision, it shall enter a decree to that effect stating the jurisdictional facts upon which the decree is based. It may then proceed immediately or at a postponed hearing within sixty (60) days to make proper disposition of the child, unless the court finds good cause to delay or postpone the hearing.(d) In detention or shelter care hearings or disposition hearings, all material and relevant evidence helpful in determining questions may be received by the court and relied upon for probative value. The parties or their counsel may examine and controvert written reports received as evidence and cross-examine persons making the reports.(e) On motion of any party or on its own motion, the court may continue a disposition hearing for a reasonable time not to exceed sixty (60) days to receive reports and other evidence bearing on the disposition to be made. The court shall make an appropriate order for detention or shelter care of the child or for his release from detention or shelter care subject to any terms and conditions the court deems necessary during the period of continuance.(f) At any time prior to disposition under W.S. 14-6-429, the court, on motion of any party or on its own motion, may reconsider its order regarding detention or shelter care or conditions of release made under W.S. 14-6-409 or 14-6-414.
