84. 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, at any time within six 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 dealer and has allowed him 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, which may be due to the dealer.

 (3) Where any such rectification has the effect of enhancing an assessment or penalty, the assessing authority shall give the dealer a revised notice of assessment or penalty and thereupon the provisions of this Act and the Rules made there under shall apply as if such notice had been given in the first instance.

(4) The powers under sub-section (1) may be exercises by the assessing authorities even though the original order of assessment, if any, passed in the matter has been the subject matter of an appeal or revision.

 (5) The provisions of this Act relating to appeal and revision shall apply to an order or rectification made under this section as they apply to the order in respect of which such order of rectification has been made.
