113. In Union of India v. Ashish Agarwal [(2022) 444 ITR 1 (SC); (2023) 1 SCC 617.] , this court allowed the assessees to avail of all the defences, including the defence of expiry of the time limit specified under section 149(1). In the instant appeals, the reassessment notices pertain to the assessment years 2013-2014, 2014-2015, 2015-2016, 2016-2017, and 2017-2018. To assume jurisdiction to issue notices under section 148 with respect to the relevant assessment years, an Assessing Officer has to : (i) issue the notices within the period prescribed under section 149(1) of the new regime read with Taxation and other Laws (Relaxation and Amendment of Certain Provisions) Act, 2020; and (ii) obtain the previous approval of the authority specified under section 151. A notice issued without complying with the preconditions is invalid as it affects the jurisdiction of the Assessing Officer. Therefore, the reassessment notices issued under section 148 of the new regime, which are in pursuance of the deemed notices, ought to be issued within the time limit surviving under the Income-tax Act read with Taxation and other Laws (Relaxation and Amendment of Certain Provisions) Act, 2020. A reassessment notice issued beyond the surviving time limit will be time-barred.‖
