Advance ruling modification is limited to mistake of law or fact and cannot be used as a review power.

Regulation 21 of the Customs Authority for Advance Rulings Regulations, 2021 permits modification of an advance ruling only where the Authority is satisfied that the ruling was pronounced under a mistake of law or fact. The provision is confined to modification and does not create a general power of review. In the Echo devices classification matter, the earlier ruling was a speaking order based on the relevant facts and law, and no mistake of law or fact was shown on the record. The modification petition was therefore not maintainable and was rejected, leaving the advance ruling undisturbed.

Issues: Whether the advance ruling on classification of the Echo devices could be modified under Regulation 21 of the Customs Authority for Advance Rulings Regulations, 2021 on the ground that it was passed under a mistake of law or fact and whether the provision conferred any power of review.

Analysis: Regulation 21 permits modification of an advance ruling only where the Authority is satisfied that the ruling was pronounced under a mistake of law or fact, and only in the manner contemplated by the regulation. The power is limited to modification and does not amount to a power of review. The earlier ruling was a speaking order passed after consideration of the relevant facts and law, and the record did not show any mistake of law or fact in the classification decision. Accordingly, the jurisdiction under Regulation 21 was not attracted.

Conclusion: The modification petition was not maintainable and was rejected.

Final Conclusion: The advance ruling remained undisturbed, and the request to reopen the classification decision was refused.

Ratio Decidendi: A provision allowing modification of an advance ruling for mistake of law or fact cannot be used as a power of review, and it applies only when such a mistake is shown to exist in the original ruling.
