Rectification of advance ruling :

The Authority or, as the case may be, the Appellate Authority may amend any order passed by it under section 98 or section 100, as the case may be, so as to rectify any mistake apparent from the record, if such mistake is noticed by the Authority or, as the case may be, the Appellate Authority on its own accord, or is brought to its notice by the prescribed or the jurisdictional CGST / SGST officer or the applicant within a period of six months from the date of the order:

Provided that no rectification which has the effect of enhancing the tax liability or reducing the amount of admissible input tax credit shall be made unless the Authority or, as the case may be, the Appellate Authority has given notice to the applicant or, as the case may be, the appellant of its intention to do so and has allowed him a reasonable opportunity of being heard.

Explanation.— For the removal of doubts, it is hereby clarified that the Authority or, as the case may be, the Appellate Authority shall not, while rectifying any mistake apparent from record, amend substantive part of its order.
