Haw. Rev. Stat. § 269E-16
After any order or decision has been made by the public utilities commission, any party to the proceeding may apply once for reconsideration or a rehearing in respect to any matter determined in the proceeding and specified in the motion for reconsideration or rehearing. The motion for reconsideration or a rehearing shall be filed within ten days after the decision and order has been served and shall set forth specifically the ground or grounds on which the applicant considers the decision or order to be unlawful. No person shall in any court urge or rely on any ground not so set forth in the motion. A motion for reconsideration or rehearing shall not excuse any person from complying with and obeying any order or decision, or any requirement of any order or decision of the commission theretofore made, or operate in any manner to stay or postpone the enforcement thereof, except in such cases and upon such terms as the commission by order directs. If, after reconsideration or rehearing the commission is 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 it. The order or decision 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 unless so ordered by the commission.
