S. 159 : Legal representatives -Reassessment-Notice issued in name of dead person is not enforceable in law- There is no statutory obligation on part of legal representative of deceased to immediately intimate death of assessee or take steps to cancel PAN registration- The proceedings under S. 159 can be invoked only if the proceedings have already been initiated when the assessee was alive and was permitted for the proceedings to be continued as against the legal heirs- The notice has to be, in substance and effect, in conformity with or according to the intent and purpose of the Act. Undoubtedly, the issue relating to limitation is not a curable defect for the revenue to invoke S. 292B. Accordingly the Court held the impugned notice is wholly without jurisdiction and cannot be enforced against the assessee. [ S. 147,148, 292BB ]
