946 ARTICLE 23

mined therein, and the Commission may grant and hold such a 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 Commis-
sion within thirty days after the same shall be finally submitted. Any
application for such a rehearing shall not excuse any common carrier, rail-
road corporation, or street railroad corporation, or any other corporation,
or company or person, subject to any of the provisions of this sub-title, from
complying with or obeying any order, or any requirements of any order of
the Commission, or operate in any manner to stay or postpone the enforce-
ment thereof, except as the Commission may by order direct. If, after
such rehearing and consideration of the facts, including those arising since
the making of the order, the Commission shall be of opinion that the orig-
inal order, or any part thereof, is in any respect unjust or unwarranted, the
Commission may abrogate, change or modify the same. An order made for
any such rehearing, abrogating, changing or modifying the original order
shall have the same force and effect as an original order.

Every order of the Commission shall be served upon every person or cor-
poration^: to be affected thereby, either by personal delivery of a certified
copy thereof, or by mailing a certified copy thereof, in a sealed package,
with postage prepaid, to the person to be affected thereby; or, in the case of
a corporation, to any officer or agent thereof upon whom summons may be
served under the laws of this State. It shall be the duty of every person
and corporation to notify the Commission forthwith in writing of the
receipt of the certified copy of every order so served, and in the case of a
corporation such notification must be signed and acknowledged by a person
or officer duly authorized by the corporation to admit such service. Within
a time specified in the order of the Commission every person and corpora-
tion upon, whom it is served must, if so required in the order, notify the
Commission in like manner whether the terms of the order are accepted
and will be obeyed.

All orders of the Commission shall take effect within such reasonable
time as it shall prescribe, and shall continue in force until its further order,
or for a specified period of time according as shall be prescribed in the
order, unless the same shall be suspended, or modified, or set aside by the
Commission, or be suspended or set aside by a court of competent jurisdic-
tion.

Any company, corporation, association, person or partnership subject
to any of the provisions of this sub-title, or other person or party in inter-
est, shall have the right to proceed in the courts to vacate, set aside or have
modified any order of said Commission on the grounds that such order is
unreasonable or unlawful, as hereinafter more particularly set forth.
