If it is known or if there is reason to know the child is an Indian child, and the child has been ordered detained pursuant to Section 319, any party may request an ex parte hearing prior to disposition to present evidence to the court that the emergency placement is no longer necessary to prevent imminent physical damage or harm to the child. If the court determines placement is no longer necessary, it shall order the child returned to the physical custody of the parent or parents or Indian custodian. The Judicial Council shall develop a rule of court and forms for implementation of this section.
