Unsigned e-proceeding notices invalidate reassessment where prescribed digital signatures are mandatory for electronic tax compliance.

Additional legal grounds challenging reassessment validity were admitted because they went to the root of the proceedings and required no further factual inquiry. In e-proceedings under sections 148A(b), 148A(d) and 148, the notices and reassessment order were issued without digital signatures. The Tribunal held that documents generated through the electronic assessment framework must comply with the prescribed digital-signature requirement, and failure to do so vitiates the reassessment. The notices and order were therefore treated as invalid, bad in law and void ab initio, and the reassessment was quashed.

Issues: (i) Whether additional grounds challenging the validity of reassessment could be admitted as purely legal grounds. (ii) Whether notices and order issued in e-proceedings under sections 148A(b), 148A(d) and 148, when not digitally signed, rendered the reassessment invalid and void ab initio.

Issue (i): Whether additional grounds challenging the validity of reassessment could be admitted as purely legal grounds.

Analysis: The additional grounds went to the root of the reassessment proceedings and did not require further factual investigation. A purely legal challenge can be entertained at the appellate stage.

Conclusion: The additional grounds were admitted.

Issue (ii): Whether notices and order issued in e-proceedings under sections 148A(b), 148A(d) and 148, when not digitally signed, rendered the reassessment invalid and void ab initio.

Analysis: The notices, order and reassessment documents were issued through the electronic assessment framework but were not digitally signed. The Tribunal applied the requirement that documents issued in e-proceedings must be digitally signed, and held that deviation from the prescribed electronic procedure vitiates the assessment.

Conclusion: The notices and reassessment order were held invalid, bad in law and void ab initio, and the assessment was quashed.

Final Conclusion: The reassessment could not survive the legal challenge based on unsigned electronic notices and order, while the remaining grounds were left open as academic.

Ratio Decidendi: Where assessment proceedings are conducted through the e-proceeding mechanism, notices and orders required to be issued electronically must bear the prescribed digital signature, and non-compliance vitiates the reassessment.
