45. Every interested person may request the board to revise any decision it has rendered which has not been appealed to the Court:
(a) to present new facts which, if they had been known in due time, could have warranted a different decision;
(b) when, being a party to the dispute, he was not able, for reasons considered sufficient, to be heard;
(c) to rectify any clerical error.
The application to that effect must be sent to the board by registered or certified letter within thirty days of the receipt of a copy of the decision by registered or certified mail.
