131. So long as a decision has not been inscribed for review or appeal, the Minister may, on his own motion or at the request of an interested person, reconsider the decision
(1) if it was rendered before an essential fact became known, or was based on an error pertaining to an essential fact;
(2) where a substantive or procedural defect is likely to invalidate it;
(3) if it contains an error in writing or in calculation or any other clerical error.
The new decision replaces the initial decision, which ceases to be effective, and the provisions concerning review and appeal apply to the new decision.
