Power to rectify any error apparent on the face of the record

(1) An assessing authority or an appellate or revising authority (including the Appellate Tribunal) may, on application or otherwise, at any time within three years from the date of any order passed by it, rectify any error apparent on the face of the record: Provided that no such rectification which has the effect of enhancing an assessment or any penalty shall be made unless such authority has given notice to the person affected and has allowed him a reasonable opportunity of being heard. (2) Where such rectification has the effect of reducing an assessment or penalty, the assessing authority shall make any refund to the person entitled thereto. (3) Where any such rectification has the effect of enhancing an assessment or penalty, the assessing authority shall give the dealer or other person a revised notice of assessment or penalty, and thereupon the provisions of this Act and the rules made thereunder shall apply as if such notice had been given in the first instance. Explanation.—The liability to pay the tax or other amount will arise only from the date specified in the revised notice.
