If a notice of demand is reduced by an order of the Adjudicating Authority under the Insolvency and Bankruptcy Code, the Assessing Officer shall modify the demand to conform with that order and serve a notice specifying the sum payable, which shall be deemed a notice under the notice-of-demand regime; where that order is later modified on appeal, the Assessing Officer shall revise the modified notice of demand accordingly.
