Motions for rehearing or reopening to change, modify, rescind or vacate a decision or order of the Board must be filed in writing with the Board within ten (10) days after service of the determination or order to which the request relates. Such motion or request shall conform to section (7) of these rules.
A.Effect of rehearing or reopening. Unless otherwise specified by the Board, a decision to grant a motion to rehear or reopen a case does not act to stay the effect of the Board's order to which the rehearing or reopening applies. A timely motion under this subsection terminates the running of time for an appeal, which then begins to run after the motion is acted upon, or deemed denied under paragraph (B) of this section.B. Any motion for rehearing or reopening that is not granted within fourteen (14) days from the date of filing shall be deemed to be denied. The Board may, on its own motion and after notice to all parties, rehear or reopen any matter at any time, to the extent permitted by law.
