The court may, for good cause, continue the hearing for as long as is reasonably required to receive additional evidence, reports, or assessments that the court has requested, or other information needed in the best interests of the juvenile and to allow for a reasonable time for the parties to conduct expeditious discovery. Otherwise, continuances shall be granted only in extraordinary circumstances when necessary for the proper administration of justice or in the best interests of the juvenile. Resolution of a pending criminal charge against a respondent arising out of the same transaction or occurrence as the juvenile petition shall not be the sole extraordinary circumstance for granting a continuance.
