(c) Upon written motion of a party filed no later than 10 days prior to hearing, or upon the court's own motion and only for good cause shown, the Court may continue the hearing for a period not to exceed 30 days, and only if the continuance is consistent with the health, safety and best interests of the minor. When the court grants a continuance, it shall enter specific factual findings to support its order, including factual findings supporting the court's determination that the continuance is in the best interests of the minor. Only one such continuance shall be granted. A period of continuance for good cause as described in this Section shall temporarily suspend as to all parties, for the time of the delay, the period within which a hearing must be held. On the day of the expiration of the delay, the period shall continue at the point at which it was suspended.
The term "good cause" as applied in this Section shall be strictly construed and be in accordance with Supreme Court Rule 231 (a) through (f). Neither stipulation by counsel nor the convenience of any party constitutes good cause. If the adjudicatory hearing is not heard within the time limits required by subsection (b) or (c) of this Section, upon motion by any party the petition shall be dismissed without prejudice.
