Advance ruling review barred except when ruling procured by fraud or misrepresentation, enabling annulment under law.

The Authority for Advance Rulings lacks jurisdiction to reconsider or review its own ruling absent a substantiated mistake of law or fact or a mistake apparent from the record warranting rectification or amendment under the procedural regulations; however, a previously announced ruling may be declared void ab initio if it is shown to have been obtained by fraud or misrepresentation of facts.
