177.1. The tribunal may correct a decision it has rendered where the decision contains an error in writing, a mistake in calculation or any other clerical error.
The decision may be corrected by the tribunal of its own initiative, as long as execution of the decision has not commenced. A correction may be effected at any time on the motion of one of the parties, served on the other parties in accordance with the Code of Civil Procedure (chapter C‐25). Moreover, the tribunal may revise any decision it has rendered(1) where a new fact is discovered which, if it had been known in due time, might have justified a different decision;
(2) where a substantive or procedural defect is likely to invalidate the decision;
(3) (subparagraph repealed).
The motion for revision must be filed within 15 days counting, according to circumstances, from the day on which the party became aware of the decision, the new fact or the substantive or procedural defect likely to invalidate the decision. The time limit of 15 days is peremptory; however, the tribunal may, on a motion, and provided that no more than six months have elapsed since the decision, relieve a party of the consequences of a failure to comply with the time limit if the party shows that it was, in fact, impossible to act sooner.
