Case Search at CESTAT

Jurisdiction Guide · CESTAT

Updated for 2026 · Claw Editorial

CESTAT decides some of the highest-value tax disputes in India, covering customs duty, central excise, and service tax appeals, yet finding the status of a pending appeal is not always straightforward. The tribunal runs nine separate benches, each with its own case list, and its numbering system (diary numbers, case numbers, and Order-in-Original or Order-in-Appeal references) confuses lawyers who are used to High Court or district court formats. This guide explains what CESTAT actually hears, how its case numbers work, how to search the official portal, and what to do when a search comes up empty.

01What CESTAT hears, and what it does not

The Customs, Excise and Service Tax Appellate Tribunal started life in 1982 as CEGAT, the Customs, Excise and Gold (Control) Appellate Tribunal, constituted under Section 129 of the Customs Act, 1962. It was renamed CESTAT in 2003, once service tax appeals were added to its jurisdiction. It remains a quasi-judicial body, not a court, and it cannot issue writs or award compensation for unlawful revenue action. It rules strictly within the statutes that created it.

What CESTAT decides

• Customs matters: valuation, classification, and duty disputes on imports and exports, appealed from orders of Commissioners of Customs.
• Central excise matters: legacy excise duty disputes that predate GST, including classification and Cenvat credit issues still working through the system.
• Service tax matters: legacy service tax disputes from before GST replaced service tax in 2017.
• Trade remedy matters: anti-dumping duty, safeguard duty, and countervailing duty appeals, heard by a special bench presided over by the CESTAT president, in matters connected to the Ministry of Commerce.

A common confusion: CESTAT does not hear GST appeals

Because GST replaced excise and service tax for most transactions after 2017, practitioners sometimes assume CESTAT is the appellate forum for GST disputes too. It is not. GST appeals go to the GST Appellate Tribunal (GSTAT), a separate body constituted under Section 109 of the CGST Act, 2017, with its own principal bench and state benches. Filing a GST appeal at CESTAT will be rejected for want of jurisdiction, and the time lost does not stop the limitation clock running for GSTAT. CESTAT continues to function for customs matters and for the legacy excise and service tax disputes that arose before the GST transition.

02The nine CESTAT benches

CESTAT sits through a Principal Bench and eight regional benches, a much smaller footprint than the High Courts or the NCLT, but the same underlying problem applies: there is no single, unified search across all of them.

Bench locations

The Principal Bench is in New Delhi. The regional benches are at Mumbai, Kolkata, Chennai, Bangalore, Ahmedabad, Allahabad, Chandigarh, and Hyderabad. Bangalore was added in 2000, Ahmedabad in 2006, and Allahabad, Chandigarh, and Hyderabad were all added in 2015 as the tribunal’s caseload grew.

Which bench hears your appeal

Jurisdiction generally follows the location of the Customs, Central Excise, or Service Tax Commissionerate that passed the order under appeal. If you are unsure which bench a matter was filed at, checking the order-in-original or order-in-appeal for the issuing Commissionerate is usually the fastest way to work it out, since that determines the CESTAT bench with territorial jurisdiction.

CESTAT has nine benches, but no single search box that spans all of them. You need to know the bench before you can find the case.

03CESTAT case and diary numbers

CESTAT’s numbering system trips up lawyers who mostly work in High Courts or district courts, because it runs on three different reference numbers rather than one.

Diary number

The diary number is assigned when an appeal is first filed with the registry, before it is formally registered as a case. It is the earliest reference point for a newly filed appeal and is often the only number available in the first few weeks after filing.

Case number (appeal number)

Once the registry scrutinises and registers the appeal, it is given a case number, sometimes called the appeal number. This is the number that appears on cause lists and in the tribunal’s final orders. It typically carries a type prefix for the kind of matter (customs, excise, or service tax appeal), a serial number, and the year.

Order-in-Original and Order-in-Appeal references

Because a CESTAT case begins life as an appeal against a departmental order, the official portal also lets you search by the underlying Order-in-Original (O-I-O) or Order-in-Appeal (O-I-A) number, that is, the number of the Commissioner or Commissioner (Appeals) order being challenged. This is useful when you have the department’s order in hand but not yet the tribunal’s own case number.

CESTAT does not use the CNR number format that High Courts and district courts use under the eCourts system. For that separate framework, see how to check case status on eCourts.

04How to search on the official CESTAT portal

CESTAT’s official website is cestat.gov.in, and case status search sits at the /casestatus page. Here is how it works.

Case status search

1. Go to the case status page and first select the bench: Delhi, Chandigarh, Mumbai, Ahmedabad, Bangalore, Allahabad, Kolkata, Chennai, or Hyderabad.
2. Choose a search type: diary number, case number, party name, or O-I-A/O-I-O number.
3. For a diary number search, enter the diary number and year, plus the captcha shown.
4. Results list the applicant and respondent names, diary number, and case number, with a link through to further detail on that appeal.

Cause lists and final order status

The portal separately publishes cause lists bench-wise, and a final order status page where you can check whether an order has been passed and released. Because CESTAT hears large volumes of similar customs and excise matters, cause lists can run long, so knowing your case number in advance makes it much faster to find your matter on the day’s list.

E-filing

CESTAT also runs a separate e-filing portal at efiling.cestat.gov.in for filing appeals and related applications electronically. This is a filing system rather than a search system, but it is worth knowing it is distinct from the main cestat.gov.in case status pages.

05Common problems and workarounds

Practitioners who regularly appear before CESTAT run into a small, predictable set of search problems.

You do not know which bench the appeal is at

Since jurisdiction follows the Commissionerate that passed the underlying order, check the order-in-original or order-in-appeal for the issuing office, which tells you the territorial bench. If that is not available, the party name search can be tried bench by bench, though this is slow across all nine benches.

Only a diary number is available

In the weeks right after filing, a matter may only carry a diary number, not yet a registered case number. Search by diary number and year rather than trying a case number search, which will return nothing until registration is complete.

Tracking several CESTAT appeals across benches

Corporate legal teams and law firms handling customs or excise disputes across multiple states often have appeals pending before several CESTAT benches at once. There is no single dashboard on the official site for this, so tracking hearing dates across benches usually means checking each bench’s cause list separately, alongside the firm’s other court and tribunal matters. For guidance on keeping cause lists organised across several courts and tribunals at once, see how to manage cause lists across multiple courts in India.

Case appears settled but no order is visible

If a hearing has taken place but the case status still shows the matter as pending, check the final order status page separately, since order upload can lag behind the hearing itself by some time. For an official, certified copy, the registry at the relevant bench remains the authoritative source.

CESTAT case tracking is one part of a broader picture. For how case search works across the Supreme Court, High Courts, district courts, and other tribunals, see case search across Indian courts.

06Where Claw fits

Claw is an all-in-one legaltech platform for Indian advocates, law firms, and corporate legal teams, combining AI-based case search, an AI legal assistant (Legal GPT), case management, and compliance automation across all Indian courts and tribunals.

CESTAT is a tribunal, and Claw’s case search product is built for judgement research across the Supreme Court and the 25 High Courts, so it is not the tool for searching CESTAT case law directly. Where Claw is genuinely useful for a CESTAT practice is on the management side. Its case management and tracking capability spans 8,200 plus courts and tribunals across India, and a team running customs, excise, or service tax appeals across several CESTAT benches can use it to keep hearing dates, cause list alerts, and matter status in one calendar instead of checking each bench’s portal separately. Its Legal GPT can also help a team read and summarise a lengthy CESTAT order once it is in hand.

For teams that also handle GST disputes, it is worth remembering that GSTAT, not CESTAT, is the forum, so tracking that side of a client’s tax litigation is a separate matter with its own timelines.
