Unsigned statutory notices lacking required authentication invalidate reassessment jurisdiction and render proceedings void ab initio.

An unsigned Section 148 notice lacking signature and authentication fails the statutory signing requirement under Section 282A(1), so it is not a valid authenticated instrument and cannot confer jurisdiction to initiate or complete reassessment under Sections 147/143(3); defects in signature are not treated as mere clerical irregularities or curable for jurisdictional purposes. The unsigned and blank notice is therefore invalid, arbitrary and void ab initio, and reassessment proceedings founded solely on such a notice lack jurisdiction and must be quashed in favour of the assessee.

Issues: Whether a notice issued under Section 148 of the Income-tax Act, 1961 that is left unsigned and blank is violative of Section 282A(1) of the Income-tax Act, 1961 and, if so, whether such unsigned notice invalidates the reassessment proceedings under Sections 147/143(3) of the Income-tax Act, 1961.

Analysis: The statutory text of Section 282A(1) requires that a notice or other document issued by an income-tax authority shall be signed and issued in paper form or communicated in electronic form in accordance with prescribed procedure. Section 282A(2) contains a deeming provision for authentication where the name and office of a designated authority is printed, stamped or otherwise written thereon, but does not relieve compliance with the mandatory signing requirement of Clause (1). Authorities holding that an unsigned notice cannot be treated as a mere clerical irregularity and that defects in signature are not curable for the purpose of assuming jurisdiction to proceed with reassessment have been applied. Where a notice under Section 148 is unsigned and blank in the signature/seal fields, the issuing authority lacks the valid authenticated instrument required by Section 282A(1), and consequently no valid jurisdiction to complete reassessment under Sections 147/143(3) can be exercised.

Conclusion: The unsigned notice issued under Section 148 of the Income-tax Act, 1961 is violative of Section 282A(1) and is held invalid, arbitrary and void ab initio; the reassessment proceedings under Sections 147/143(3) therefore lack jurisdiction and are quashed. The decision is in favour of the assessee.
