386.500.  Rehearing before commission. — 1.  After an order or decision has been made by the commission, the public counsel or any corporation or person or public utility interested therein shall have the right to apply for a rehearing in respect to any matter determined therein, and the commission shall grant and hold such rehearing, if in its judgment sufficient reason therefor be made to appear; if a rehearing shall be granted the same shall be determined by the commission within thirty days after the same shall be finally submitted.

  2.  No cause or action arising out of any order or decision of the commission shall accrue in any court to any corporation or the public counsel or person or public utility unless that party shall have made, before the effective date of such order or decision, application to the commission for a rehearing.  Such application shall set forth specifically the ground or grounds on which the applicant considers said order or decision to be unlawful, unjust or unreasonable.  The applicant shall not in any court urge or rely on any ground not so set forth in its application for rehearing.

  3.  An application for a rehearing shall not excuse any corporation or person or public utility from complying with or obeying any order or decision or any requirement of an order or decision of the commission, or operate in any manner to stay or postpone the enforcement thereof except as the commission may by order direct.

  4.  If, after a rehearing and a consideration of the facts, including those arising since the making of the order or decision, the commission shall be of the opinion that the original order or decision or any part thereof is in any respect unjust or unwarranted, or should be changed, the commission may abrogate, change or modify the same.  An order made after any such rehearing, abrogating, changing or modifying the original order or decision shall have the same force and effect as an original order or decision but shall not affect any right or the enforcement of any right arising from or by virtue of the original order or decision.
