Case Search at TDSAT

Jurisdiction Guide · TDSAT

Updated for 2026 · Claw Editorial

TDSAT is a small tribunal by bench count, but the matters before it, telecom licensing disputes, TRAI orders, broadcasting tariffs, airport charges, and cyber appeals, are often high value and time sensitive. Yet TDSAT sits outside the eCourts network that most Indian lawyers rely on for case status, so a search habit built for district courts or High Courts does not carry over. This guide explains how TDSAT case status search actually works, what a diary number and a case number mean here, and where to look for cause lists and orders.

01What TDSAT hears

The Telecom Disputes Settlement and Appellate Tribunal was set up in 2000, under an amendment to the TRAI Act, to take dispute resolution out of the regulator’s own hands. Before TDSAT existed, the Telecom Regulatory Authority of India both made rules and adjudicated disputes about them. TDSAT separated the two functions, so TRAI now regulates and TDSAT decides the disputes and appeals that follow.

Core subject matters

• Telecom disputes and appeals: Disputes between licensors, licensees, and service providers under the TRAI Act, and appeals against TRAI directions, orders, or decisions. This remains the tribunal’s founding jurisdiction and its largest category.
• Broadcasting and cable appeals: Disputes and appeals connected to broadcasting services and cable television tariffs, since TRAI also regulates this sector.
• AERA appeals: Appeals against orders of the Airports Economic Regulatory Authority, mainly around airport tariffs and charges. This jurisdiction was added later and now runs alongside telecom and broadcasting matters.
• Cyber appeals: TDSAT also hears appeals that were earlier the domain of the Cyber Appellate Tribunal, after that tribunal’s functions were merged into TDSAT.
• Review applications and miscellaneous applications: Procedural and interlocutory matters filed within a main petition or appeal.

The principal bench sits in New Delhi, at Chanakyapuri. Unlike a High Court or the NCLT, TDSAT does not have a network of permanent regional benches. It has, in recent years, started holding circuit sittings in other cities such as Chennai so that parties from that region do not always have to travel to Delhi. For most matters, though, Delhi remains the seat you need to track.

02Diary number vs case number at TDSAT

TDSAT uses a two-stage numbering system that trips up lawyers used to the CNR-based system in district courts and High Courts.

Diary number

When a petition, appeal, or application is first filed, it is given a diary number. This is a temporary receipt-style number confirming the filing was received. It does not yet reflect the tribunal’s scrutiny of whether the case is properly formed.

Case number

After registry scrutiny, the matter is assigned a formal case number under its category, for example a Petition, Appeal, Miscellaneous Application, or Review Application, along with a serial number and year. This is the number used in cause lists, orders, and citations once the matter is on the tribunal’s regular docket.

At TDSAT, a diary number tells you a filing was received. A case number tells you it has been registered and is on the docket. The two searches on the official portal reflect that difference, and using the wrong one is the most common reason a search comes back empty.

This diary-to-case-number pattern is similar in spirit to what happens at the Supreme Court and some High Courts, but TDSAT’s system is entirely separate from CNR numbers and from eCourts. A case moving from a High Court to TDSAT, or vice versa on appeal, will carry unrelated numbers at each stage. If you regularly work across both systems, our guide to using eCourts case status as a lawyer covers the CNR-based system separately, since it does not apply here.

03How to search case status on the official portal

TDSAT publishes case status directly on its own website, tdsat.gov.in, rather than through the eCourts platform used by most other courts and tribunals.

Steps to search case status

1. Go to the Case Status page on the official TDSAT site.
2. Choose whether to search by Case Number or by Diary Number. Use diary number if the matter is newly filed and not yet on the regular docket; use case number once it has been registered.
3. Select the case type from the dropdown. The categories on the official form include Telecom appeals and petitions, Broadcasting appeals and petitions, AERA appeals and petitions, Cyber appeals, Review applications, and miscellaneous applications.
4. Enter the number and year, then submit. The result shows the current status, the next listed date if any, and, where uploaded, a link to the order.

Because there is no unified national tribunal search that covers TDSAT alongside other tribunals, this official portal is the authoritative first stop for any TDSAT matter, whether you are checking your own case or verifying the status of one on the other side.

04Cause lists and daily orders

TDSAT publishes a daily cause list on its website, usually the evening before the hearing date, listing the matters to be taken up and their sequence. It also maintains a daily order list, showing orders passed on a given day, and a separate judgements section for final orders and rulings.

These are useful for three different needs. If you are appearing the next day, the cause list tells you the bench and the likely sequence. If you want to know whether an order was passed in a matter you are tracking, the daily order list is the quickest check. If you are researching how TDSAT has ruled on a point in the past, the judgements section is the starting point, though for citation-grade research across a broader set of tribunal and court rulings, a dedicated legal research database is usually more complete.

Checking these lists manually, every day, across multiple matters is one of the more tedious parts of a telecom or broadcasting litigation practice. Firms handling several TDSAT matters at once often look for ways to get the relevant part of the cause list pushed to them automatically rather than checking the portal each evening. See our guide on getting your cause list on WhatsApp for how that kind of automated alert works in practice.

05Common problems and workarounds

A few issues come up repeatedly for lawyers and in-house teams tracking TDSAT matters.

Search returns nothing

The most frequent cause is searching by case number when the matter is still only at the diary number stage, or the reverse, searching by diary number after the case has already been registered and renumbered. If you are not sure which stage a matter is at, try both searches, or search by party name instead.

Uncertain which case-type category to pick

Because TDSAT hears telecom, broadcasting, AERA, and cyber matters under one roof, it is easy to select the wrong category on the search form and get a false empty result. If your first search fails, re-check the subject matter of the dispute against the categories listed on the portal before assuming the case is not there.

No single search across TDSAT and other tribunals

TDSAT’s portal only covers TDSAT. If your practice also involves matters before other specialised tribunals, for example real estate disputes before RERA authorities, you will need to search each one separately using its own system. See our guide to RERA case management software in India for how that tracking works for real estate matters. For a broader view of how case search differs across Indian courts and tribunals generally, see case search across Indian courts.

Tracking multiple TDSAT matters over time

Telecom operators, broadcasters, and airports frequently have several TDSAT matters running at once, sometimes over years, since telecom and tariff disputes can take a long time to resolve. Manually revisiting the portal for each matter, on each hearing date, is easy to fall behind on, especially when the same legal team is also covering High Court and Supreme Court appeals arising from the same dispute.

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.

For TDSAT specifically, Claw’s role is on the tracking and management side rather than judgement research. Claw’s AI-based case search product covers the Supreme Court and 25 High Courts, and does not extend to tribunal-level judgement search such as TDSAT rulings, so for citing TDSAT case law, the established legal research databases remain the right tool. Claw’s separate case management and tracking layer, however, covers 8,200 plus courts and tribunals across India, which includes TDSAT. For a firm or in-house telecom, broadcasting, or airports legal team with multiple matters at TDSAT, that means auto-updated case status, a shared calendar, cause list and hearing alerts over WhatsApp and email, and AI-assisted reading of tribunal orders to flag deadlines, without a person checking the TDSAT portal by hand every day.

That combination matters most for teams juggling TDSAT alongside related proceedings, for instance a TRAI dispute at TDSAT running in parallel with a Supreme Court appeal from an earlier TDSAT order, or a telecom licensee tracking several regional disputes at once. The tracking layer keeps all of it visible in one place, even though the underlying research for any TDSAT judgement still starts on the tribunal’s own site or a specialist database.
