After an order has been made by the commission any corporation or person interested therein shall have the right to apply for a rehearing in respect to any matter determined therein, but any such application must be made within thirty days after the service of such order, unless the commission for good cause shown shall otherwise direct; and the commission shall grant and hold such a rehearing if in its judgment sufficient reason therefore be made to appear. The decision of the commission granting or refusing the application for a rehearing shall be made within thirty days after the making of such application. If a rehearing shall be granted, the same shall be determined by the commission within thirty days after the same shall be finally submitted. An application for such a rehearing shall not excuse any corporation or person from complying with or obeying any order or any requirement of any order of the commission, or operate in any manner to stay or postpone the enforcement thereof except as the commission may by order direct. If, after such rehearing and a consideration of the facts, including those arising since the making of the order, the commission shall be of opinion that the original order or any part thereof is in any respect unjust or unwarranted, or should be changed, the commission may abrogate or change the same. An order made after any such rehearing abrogating or changing the original order shall have the same force and effect as an original order but shall not affect any right or the enforcement of any right arising from or by virtue of the original order.
