In any formal proceeding, where the commissioner finds that the interests of the public require that immediate action be taken pending the completion of the hearings, the making of a determination thereon and the entry of a final order, he may enter an appropriate order to be effective pending the hearing and until the entry of a final order. Such orders may be entered on ex parte proofs where the proofs are strong and the need is great, but ex parte orders shall be subject to application to vacate on 2 days’ notice, and a preliminary hearing on the ex parte order shall be held in any event within not more than 20 days after entry thereof. In the alternative, or in addition thereto, the commissioner shall be authorized to institute a proceeding in the Superior Court, to be conducted in a summary manner, for an injunction against specified acts or conduct in aid of the proceedings pending before him, including temporary injunctions and interim restraints, upon a showing that such remedy would be more effective and complete.
