Ten Landmark GSTAT Decisions Shaping the Future of GST Law in India

Introduction: The Rise of a Specialised GST Appellate Forum

The establishment and operationalisation of the Goods and Services Tax Appellate Tribunal (GSTAT) represents a defining moment in the maturation of Indian GST law. For nearly nine years following the rollout of GST, assessees and tax professionals had to rely primarily on High Court pronouncements, Advance Ruling Authority orders, and departmental circulars to navigate interpretational grey areas. The emergence of GSTAT as a functioning specialised forum has fundamentally altered this landscape.

Adding significant momentum to this development is the release of the GSTAT E-Journal, Volume I, which compiles decisions rendered up to 31 August 2026. Conceived as an authoritative dissemination platform for GSTAT rulings, the E-Journal has been formally endorsed by the Hon'ble President of GSTAT, who, in the Foreword, underscored the values of certainty, consistency, and accessibility in GST jurisprudence. The availability of authentic, directly sourced GSTAT decisions will be of immense value to assessees, practitioners, departmental officers, courts, and academic institutions alike.

The inaugural volume contains twenty regular GST decisions alongside anti-profiteering matters. This article examines ten rulings from that volume that carry jurisprudential significance well beyond the particular facts of each case. These decisions collectively address some of the most persistently contested areas of GST law — from the Section 73/Section 74 divide and transitional credit under Section 140, to intermediary services, bill-to-ship-to transactions, personal hearing requirements, and statutory time limits.

1. Sterling & Wilson Pvt. Ltd. v. Commissioner, Odisha

Citation: (2026) 1 GSTAT E-Journal 1 — Principal Bench

Whether a discrepancy between figures reported in GSTR-1 and GSTR-3B is sufficient to sustain proceedings under Section 74 of the CGST Act, and what is the scope of GSTAT's appellate jurisdiction on questions of fact.

Facts and Decision

In this case, a difference of approximately ₹27.06 lakh existed between the assessee's GSTR-1 and GSTR-3B filings. The assessee clarified that debit/credit notes and related adjustments had been properly recorded in its books of accounts but were not correctly reflected in periodic returns. The Tribunal held that proceedings under Section 74 cannot be sustained on the basis of a return mismatch alone, where fraud, wilful misstatement, or suppression with intent to evade tax has not been independently established.

Further, where Section 74 proceedings fail on account of the absence of these jurisdictional ingredients, Section 75(2) mandates that the Proper Officer redetermine liability as though a notice had been issued under Section 73. Crucially, the Tribunal clarified that the appellate authority is not empowered to undertake this redetermination itself.

GSTAT also affirmed that it functions as the last fact-finding appellate forum under GST and that its jurisdiction is broader than a second appeal confined to substantial questions of law.

Jurisprudential Significance

A discrepancy in returns is merely an evidentiary starting point — it does not, by itself, constitute proof of fraud. Section 74 carries independent jurisdictional prerequisites that must be satisfied before it can be invoked.

This ruling is poised to become a leading reference point on the distinction between Section 73 and Section 74 and on the broader architecture of appellate remedies under GST.

2. Tata Unistore Ltd. v. Commissioner CGST & Ex., Navi Mumbai

Citation: (2026) 1 GSTAT E-Journal 37

Whether GST authorities possess the power to reopen and re-examine the admissibility of CENVAT or VAT credit earned under the pre-GST regime when adjudicating a claim for transitional credit under Section 140 of the CGST Act.

Facts and Decision

The Tribunal ruled that GST authorities cannot conduct a fresh examination under Section 74 in respect of credit that was validly standing in the assessee's books under the erstwhile tax regime, particularly where such credit had never been challenged under the earlier law. Any dispute regarding wrong availment of credit under the former regime had to be raised and resolved through the provisions of that law.

The Tribunal also accepted the transition of Krishi Kalyan Cess by following the applicable jurisdictional High Court ruling, and rejected the denial of VAT credit that was unsupported by any specific evidentiary basis.

Jurisprudential Significance

Transitioning credit into the GST framework does not vest GST authorities with a fresh jurisdictional mandate to reopen or reassess the original eligibility of that credit under the predecessor law.

This decision draws a clear jurisdictional boundary between the legitimate facilitation of credit transition under Section 140 and the impermissible reopening of historical entitlements that had already attained finality.
