On a writ petition, allowing the petition, that there could exist only one assessment order for an assessee for one assessment year. Since the reassessment order had already been passed on March 28, 2022 for the assessment year 2017-18, there was no proceeding pending to have been influenced or affected or governed by the order of the Supreme Court dated May 4, 2022 in UOI  v. Ashish Agarwal (2022) 444 ITR 1 (SC).   In the absence of any declaration of law to annul or set aside the pre-existing reassessment under section 147 and assessment order dated March 28, 2022, after issuing notice under section 148, the assessing authority had no jurisdiction to reissue the notice dated July 30, 2022 under section 148A. The proceedings were without jurisdiction and a nullity, and therefore, quashed.(AY.2017-18)
