§ 89. Rehearing before commissioner. After an order has been made by
the commissioner 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 commissioner for good cause shown
shall otherwise direct; and the commissioner shall grant and hold such a
rehearing if in his judgment sufficient reason therefor be made to
appear. The decision of the commissioner 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 commissioner 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 commissioner,
or operate in any manner to stay or postpone the enforcement thereof
except as the commissioner may by order direct. If, after such rehearing
and a consideration of the facts, including those arising since the
making of the order, the commissioner shall be of the opinion that the
original order or any part thereof is in any respect unjust or
unwarranted, or should be changed, the commissioner 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.
