The Assessing Officer issued a notice under section 148 to a company that had already ceased to exist following its amalgamation with the petitioner-company. The High Court, quashing the notice, held that its issuance to a non-existent entity was a fundamental jurisdictional defect. Following the precedent set by the Supreme Court, the Court clarified that such an error is not a mere procedural or clerical mistake that can be rectified under section 292B of the Income-tax Act, 1961. (AY. 2009-10)
