A Seven-Year Gap Finally Closes

For the better part of seven years, the Goods and Services Tax regime lived with a structural hole where an appellate tribunal should have been. An aggrieved taxpayer could file the first appeal before the Appellate Authority under Section 107 of the CGST Act, 2017, but the statutory second appeal under Section 112 — to the GST Appellate Tribunal — was on paper only, because the tribunal itself had not been constituted. That hole pushed thousands of second-stage disputes into High Courts under writ jurisdiction, where they sat not because a writ was the right remedy but because it was the only remedy. As of the start of FY 2026-27, the appellate ecosystem the statute always contemplated is now actually running, with the Principal Bench at New Delhi and a growing list of State Benches taking up appeals in phases. The Chennai Bench issued Public Notice F. No. GSTAT/Chennai/Misc/01/2026 dated 1 April 2026 confirming bench-level operations. This note is a first-time filer's roadmap — what GSTAT is, what to file, and how to use the freshly-live forum without tripping over the procedural corners.

Timeline: From Launch to Live Hearings

The sequence of events matters, because dates decide which version of the rules applies to your file:

  • 24 September 2025: GSTAT formally launched by Finance Minister Nirmala Sitharaman at a function in New Delhi, with the Principal Bench and administrative infrastructure being put in place. GSTAT also issued an initial staggering order the same day on the sequencing of backlog appeals.
  • 16 December 2025: GSTAT revoked the 24 September 2025 staggering order with effect from 18 December 2025 via a Presidential Order. The one-time filing window framework that many early write-ups still refer to is no longer the operative instrument, and practitioners must now read the current Presidential Orders and portal advisories on the e-filing portal before acting on any filing schedule.
  • 22 January 2026: The Chennai Bench members assume charge, marking the bench becoming operational per the PIB release of that date.
  • Early 2026: Hearings begin in phases at the Principal Bench and select State Benches. Exact start dates for each bench are in the bench-specific public notices on the e-filing portal; use those rather than secondary dates.
  • 1 April 2026: The Chennai Bench issues Public Notice F. No. GSTAT/Chennai/Misc/01/2026 confirming current listing/jurisdiction arrangements for the bench.

Practitioners should track further bench notifications closely, because jurisdiction and acceptance of filings are bench-specific and are being rolled out in phases. Rely on the Presidential Orders and the current portal advisories as they stand on the date you are filing, not on the September 2025 staggering order which has been revoked.

Constitutional and Statutory Framework

GSTAT draws its existence and powers from Sections 109 to 114 of the CGST Act, 2017, read with the corresponding SGST/UTGST provisions and the GSTAT (Procedure) Rules, 2025. Section 109 provides for the constitution of the Appellate Tribunal, the Principal Bench at New Delhi, and State Benches at locations notified on the recommendation of the GST Council. Section 110 deals with qualifications, appointment and conditions of service of the President and Members. Section 111 sets out the procedural powers of the Tribunal, including its ability to regulate its own procedure and to deal with matters by reference to the Code of Civil Procedure for specified purposes. Section 112 is the operative provision for appeals — who can appeal, within what time, with what pre-deposit, and the stay consequence. Section 113 deals with orders of the Appellate Tribunal and Section 114 with the financial and administrative powers of the President.

Practitioners drafting a Section 112 appeal should read these provisions alongside the GSTAT (Procedure) Rules, 2025 and any current Presidential Orders or advisories issued from the e-filing portal, because the procedural rules govern everything from page limits to the manner of uploading annexures.

Bench Architecture: Principal Bench Plus State Benches

The architecture is deliberately federal. A Principal Bench sits at New Delhi and hears, among other things, matters involving place-of-supply disputes that cut across States. State Benches sit at locations notified on the recommendation of the GST Council and handle appeals for their respective territorial jurisdictions. The Principal Bench and State Benches are constituted in the manner set out in Section 109, with Judicial and Technical Members from the Centre and the State as prescribed, reflecting the dual-tax character of GST itself. The exact composition of a given bench sitting is governed by the statute and the GSTAT (Procedure) Rules, and should not be read as a rigid one-judicial-plus-two-technical formula for every matter.

For a first-time filer the immediate question is which bench is the correct forum. That is not always intuitive — early advisories from the Chennai and Kolkata benches, for example, have made clear that until full bench-wise portal functionality is in place, some appeals may be routed through nominated benches. Read the latest public notice from the bench with apparent jurisdiction over your matter before filing, because filing in the wrong forum is a cleanable defect but a real one.

Backlog Filings and the Limitation Position

Much of the first wave of public commentary on GSTAT referred to a "30 June 2026 one-time staggered filing window" under the 24 September 2025 staggering order. That order was revoked by GSTAT on 16 December 2025 with effect from 18 December 2025, and the relief it offered can no longer be assumed. The current limitation position for a Section 112 appeal is the one that emerges from reading Section 112 together with the live Presidential Orders and portal advisories on the date of filing. Practitioners carrying forward backlog appeals that had been parked on the footing of the revoked order should treat each file as a live limitation exercise and take instructions on whether any condonation route remains available on the specific facts.

Who this affects: anyone holding an adverse order of the First Appellate Authority under Section 107 that is ripe for a Section 112 appeal, particularly where the order was communicated in a window during which the tribunal was not physically functional. Taxpayers currently running a writ petition before a High Court on the footing that GSTAT did not exist should urgently revisit that petition with counsel, because once GSTAT is live the usual answer from a constitutional court will be that the statutory remedy must now be pursued.

A practical warning: even once the correct statutory position for your file is identified, do not file at the last moment. The e-filing portal has seen concurrency-related issues at peak load, and a filing that misses a limitation date because of a portal failure is a very expensive kind of mistake to recover from.

Pre-Deposit and Appeal Mechanics Under Section 112

The pre-deposit architecture for a GSTAT appeal sits on top of what was paid at the first appeal stage under Section 107. At the Section 107 first appeal, the appellant ordinarily pays the admitted liability in full plus a percentage of the remaining disputed tax as pre-deposit. On a Section 112 appeal to GSTAT, the appellant pays a further percentage of the remaining disputed tax over and above what was already paid at Section 107. The exact percentages and monetary caps have been amended by successive Finance Acts and GST Council recommendations — recent changes have adjusted both the percentage and the rupee cap, and a distinct rule applies to penalty-only appeals. Practitioners should verify the current percentage, the current cap, and the treatment of penalty-only appeals against the text of Sections 107(6) and 112(8) as they stand on the date the appeal is filed, rather than relying on older commentary.

Two points tend to get missed in first-time filings. First, follow the current GSTAT portal and bench instructions for the prescribed mode and route of pre-deposit payment, and verify the payment path (portal workflow, Bharatkosh, or the Electronic Cash Ledger as applicable) on the date you are filing rather than assuming the route from pre-2026 commentary. Second, payment of the statutory pre-deposit triggers an automatic stay under Section 112(9) on recovery of the balance of the disputed demand for the duration of the appeal, which is exactly the protection the writ-stage interim order was doing duty for. That substitution — from a discretionary writ-stage stay to a statutory appellate stay — is one of the underappreciated benefits of GSTAT becoming live.

The GSTAT e-Courts Portal in Practice

Filings are made through https://efiling.gstat.gov.in/. Registration is required before the first filing, and thereafter the portal tracks cases, issues listing information, and surfaces cause lists. Current advisories indicate that only PDF uploads are accepted, with prudent limits on file size and scan resolution — very large scans at high DPI can cause upload failures and should be optimised before submission. Virtual hearings are provided for where a bench so directs, which is a meaningful cost saver for taxpayers whose jurisdictional bench is not in their home city.

First-time registrants should budget extra time for verification, mandatory document uploads, and resolving any mismatches between GSTIN, PAN and authorised signatory details in the portal's records. These are not dramatic issues individually, but they are exactly the kind of avoidable friction that eats a filing deadline.

Practitioner Checklist for Your First GSTAT Filing

  1. Audit every pending writ and every Section 107 order on hand. Tag each by communication date of the first appellate order and map the live limitation position against the current Presidential Orders and Section 112 text — do not rely on the revoked 24 September 2025 staggering framework.
  2. Confirm bench jurisdiction. Read the latest public notice from the bench that appears to have jurisdiction, and confirm whether filings are being accepted directly at that bench or routed through a nominated bench during the phased rollout.
  3. Compute pre-deposit against current statutory text. Pull the live text of Sections 107(6) and 112(8) and compute the additional pre-deposit due at the Section 112 stage, net of what was already paid at Section 107. Verify the monetary cap and any penalty-only appeal carve-out as they stand on filing date.
  4. Fund the prescribed pre-deposit route in advance. Whether the current portal workflow routes pre-deposit through the Electronic Cash Ledger or a separate payment gateway, fund the applicable route with sufficient lead time — same-day funding failures are a recurring reason filings miss deadlines.
  5. Prepare the appeal memorandum against the GSTAT Procedure Rules. Grounds of appeal, verification, vakalatnama, list of dates, list of documents, and annexures should be formatted to the procedure rules and the portal advisories.
  6. Clean your PDFs. Scan at a reasonable DPI, check the total size against the portal's stated cap, and run the OCR pass so searchable text is preserved where possible.
  7. File early, not at the wire. Regardless of the specific limitation date that applies to your file, build in a week's buffer to handle portal glitches, defect memos, and resubmissions.
  8. Revisit parallel writ proceedings. Where the matter is pending in a High Court under writ jurisdiction on the ground that GSTAT did not exist, prepare to withdraw or convert, and factor that into the appeal grounds.

Closing Note

GSTAT going live is not just an administrative milestone. It restores the two-tier statutory appellate structure the CGST Act always promised and takes GST disputes out of the writ queue where they had no business sitting. For the next few months, however, live operation and one-time backlog clearance are running simultaneously, and practitioners working at that intersection should treat each filing as a rule-bound exercise: verify the current statutory percentages and caps, read the latest bench-level notices, file early in the window, and keep a clean paper trail of portal acknowledgements. The forum is new, the window is narrow, and the margin for procedural error is smaller than it looks.
