22.1. The Board may, on the application of any interested person, review any decision it has rendered.
An application must be made in writing, within 60 days of notification of the contested decision, and must state briefly the grounds on which it is based.
The Board may extend the 60-day time limit or relieve a person of the consequences of failing to comply with it if it is shown that the application for review cannot or could not, for a valid reason, be made within the prescribed time.
The application for review suspends execution of the contested decision, unless the Board orders provisional execution where so justified by circumstances.
