S. 260A: Appeal – High Court – Assessment – Once a Resolution Plan is approved under section 31 of the Insolvency and Bankruptcy Code, all statutory dues, including income-tax claims, which do not form part of the approved Resolution Plan stand extinguished. Consequently, any appeal by the Revenue seeking to revive such tax demand becomes academic, and no substantial question of law arises. [S. 143(3), Insolvency and Bankruptcy Code, 2016, S. 31 ]
