Electronic GST service requires provable communication before appellate limitation begins, while portal upload alone is insufficient.
Section 169 permits service by e-mail or through the Common Portal as alternative statutory modes, without requiring prior physical service; service by affixation is available only where earlier modes are impracticable. However, the deeming provisions for service do not extend to e-mail or portal uploads. Mere electronic dispatch, alerts, or portal availability do not commence appellate limitation without proof of actual or constructive communication of the notice or order and its contents. Where timely appeal is claimed from actual communication, the revenue must establish earlier effective communication; asserted physical communication prevails unless disproved.
Issues: (i) Whether the modes of service under Section 169(1) of the GST enactments are hierarchical and whether electronic service is legally valid; (ii) Whether uploading a show-cause notice or adjudication order on the Common Portal, or dispatching an electronic alert, constitutes deemed or effective communication for commencing limitation under Section 107; (iii) Whether the petitioners should be relegated to the appellate remedy notwithstanding the disputed communication of the adjudication orders.
Issue (i): Whether the modes of service under Section 169(1) of the GST enactments are hierarchical and whether electronic service is legally valid.
Analysis: Section 169(1)(a) to (e) provides alternative modes of service available at the revenue's choice, including service by e-mail and by making a communication available on the Common Portal. Service by affixation under Section 169(1)(f) is distinct and may be used only where the preceding modes are not practicable. Electronic service is consequently a permissible and valid statutory procedure, but the provision does not establish a priority requiring physical service before electronic service.
Conclusion: Electronic service through e-mail or the Common Portal is valid in law, and no hierarchy exists among the modes in Section 169(1)(a) to (e); affixation may be adopted only upon satisfaction that those modes are impracticable.
Issue (ii): Whether uploading a show-cause notice or adjudication order on the Common Portal, or dispatching an electronic alert, constitutes deemed or effective communication for commencing limitation under Section 107.
Analysis: The statutory fiction in Section 169(2) and (3) applies to tendering, publication, affixation, and dispatch by registered or speed post in the specified circumstances, but does not extend to e-mail or Common Portal service. A legal fiction cannot be enlarged beyond its language and purpose. The Information Technology Act, 2000 applies to electronic records and their dispatch or receipt, but its provisions do not convert portal uploading or an alert into actual or constructive service under Section 169. GSTN could not identify when a taxpayer accessed, retrieved, downloaded, opened, or viewed the relevant electronic record, and the e-mails did not contain the complete notices or adjudication orders. Effective communication for an appeal requires actual or constructive knowledge of the order's contents. Where an assessee declares that an appeal is within time from actual communication, the revenue bears the burden of proving an earlier effective communication. If both physical and electronic communication are asserted, physical communication prevails unless disproved.
Conclusion: Mere uploading on the Common Portal or electronic dispatch without verifiable access, acknowledgement, or actual or constructive communication does not commence limitation under Section 107.
Issue (iii): Whether the petitioners should be relegated to the appellate remedy notwithstanding the disputed communication of the adjudication orders.
Analysis: The preliminary objection based on alternative remedy failed because the revenue could not establish effective communication from which the tightly prescribed appellate limitation could run. Consistency with the relief granted in similarly situated matters required restoration of the petitioners' opportunity to contest the demands before the adjudicating authority, subject to deposit of 10% of the disputed tax demand.
Conclusion: The petitioners were not relegated to the appellate remedy; the adjudication orders were set aside and the matters remitted for fresh adjudication subject to the prescribed deposit.
Final Conclusion: The statutory appellate right must remain real and effective; in the absence of provable actual or constructive communication of electronic notices and orders, taxpayers retain the opportunity for a fresh adjudication.
Ratio Decidendi: A statutory deeming fiction for service cannot be extended to electronic modes omitted from its terms, and limitation for an appeal begins only upon actual or constructive communication that gives the affected person a reasonable opportunity to know the order and its contents.
