Review of appellate orders allows reconsideration for new evidence or apparent errors, subject to notice and hearing. The appellate authority may, on application, review and pass orders altering its own decision where there is discovery of new and important evidence, an apparent error on the face of the record, or other sufficient reason; such orders require notice to all interested parties and a reasonable opportunity to be heard, and the application for review must be made within a prescribed short period from communication of the appellate order.
