GST appeal limitation and electronic authentication defects: outer time limit cannot be extended, and technical omissions do not invalidate orders.

A statutory appeal under the Bihar GST law cannot be entertained beyond the outer limitation period, including the one-month condonable extension and any period protected by the Supreme Court's COVID-related directions; once that maximum period expires, neither the authority nor the court can condone delay. The commentary also states that absence of a digital signature does not by itself invalidate assessment-related orders where the record shows issuance through the electronic system, the orders are otherwise in substance compliant with the Act and rules, and the objection was not raised at the proper stage. Mere technical defects in electronic authentication do not warrant interference.

Issues: (i) Whether the delayed appeal could be entertained beyond the limitation period prescribed under the Bihar Goods and Services Tax Act, 2017 and the extension granted by the Supreme Court. (ii) Whether the absence of digital signature on the assessment and allied orders invalidated the proceedings or warranted interference.

Issue (i): Whether the delayed appeal could be entertained beyond the limitation period prescribed under the Bihar Goods and Services Tax Act, 2017 and the extension granted by the Supreme Court.

Analysis: The limitation for filing appeal under Section 107 of the Bihar Goods and Services Tax Act, 2017 was three months, with a further condonable period of one month. The period of limitation was also protected during the pandemic by the Supreme Court's extension order, and even on that basis the appeal had to be filed by the last permissible date. The appeal was filed after the maximum permissible period. Neither the appellate authority nor the Court had power to condone delay beyond the statutory limit and the period extended by the Supreme Court.

Conclusion: The delay could not be condoned and the appeal was barred by limitation.

Issue (ii): Whether the absence of digital signature on the assessment and allied orders invalidated the proceedings or warranted interference.

Analysis: Rule 26(3) was read to permit electronic issuance of orders through digital signature, e-signature, or any other notified mode of verification. The records showed issuance of liability intimation, show cause notice, and assessment order with the officer's signature, and the orders were also auto-populated through the statutory electronic mechanism. Section 160 of the Bihar Goods and Services Tax Act, 2017 protected proceedings from invalidation for mere mistake, defect, or omission when they were otherwise in substance in conformity with the Act, and also prevented challenge to service where the order had already been acted upon and the objection had not been raised at the earlier stages. The objection was not taken before the assessing authority or the appellate authority and was raised belatedly.

Conclusion: The absence of digital signature did not invalidate the proceedings and did not justify interference.

Final Conclusion: The writ petition failed on both limitation and merits of the procedural challenge, and the impugned orders were left undisturbed.

Ratio Decidendi: A statutory appeal cannot be entertained beyond the maximum period of limitation prescribed by the GST law and the judicial extension of limitation, and a mere technical omission in electronic authentication does not invalidate proceedings where the action is otherwise in conformity with the Act and the objection was not raised at the proper stage.
