N.Y. PBS Law § 22

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