In short. File an Original Application in Form I under section 19 of the Administrative Tribunals Act 1985, with the impugned order and documents in a paper book, at the CAT bench covering your posting (the Principal Bench in Delhi). File within one year of the final order on your appeal or representation, or within a year after six months pass without a decision. The fee is ₹50.
This post is about the mechanics of filing an OA: deciding whether your case belongs in the CAT, picking the right bench, working out limitation, drafting the application, putting the paper book together, asking for interim relief, and what happens from the first listing to the final order. It is written for central government employees, Delhi government and Delhi Police employees, staff of notified public bodies, and retired employees with pension or pay disputes. It reflects the law as of October 2026.
The substance of particular disputes has its own posts: promotion and seniority disputes, pension disputes for retired employees, challenging a transfer order and suspension rules and remedies. For an overview of the firm's service law work, see service laws and CAT practice.

What is an Original Application in the CAT, and who can file one?
An Original Application is the first case you file before the Central Administrative Tribunal about a 'service matter': appointment, pay, promotion, seniority, transfer, suspension, disciplinary penalties, leave, retirement benefits, pension and similar conditions of service. Section 19 of the Administrative Tribunals Act lets any person aggrieved by an order relating to a matter within the Tribunal's jurisdiction apply to it for redressal. 'Order' includes a failure to act, so a representation left undecided can also be the basis of an OA.
The person filing is the applicant; the government and its officers are the respondents. Serving employees, retired employees, those dismissed or removed, and candidates for central government posts (in recruitment disputes) can all file. The applicant can appear in person or through an advocate; section 23 allows both. Many applicants start in person and engage counsel once the respondents file their reply.
Each OA should deal with one cause of action. If you have a pay fixation grievance and a separate disciplinary penalty, they are two applications. Several employees with the same grievance can, with the Tribunal's permission, file one joint application, and an association can file on behalf of its members if at least one affected member joins.
Does your case go to the CAT or the High Court?
The CAT hears service matters of central government employees, members of the all-India services, civilians working in defence establishments, and employees of bodies the Central Government has notified under section 14(2), which include many public sector undertakings, autonomous bodies and statutory corporations. Employees of the Government of NCT of Delhi and Delhi Police also go to the CAT Principal Bench, because Delhi's services fall within the Tribunal's jurisdiction. If you are in one of these groups, you cannot go straight to the High Court with a service dispute; the High Court will send you to the Tribunal first.
Members of the armed forces go to the Armed Forces Tribunal, not the CAT. Staff of the Supreme Court, the High Courts and the Parliament secretariats are outside the Act. State government employees go to their state forum: in Uttar Pradesh, the State Public Services Tribunal; in Haryana, the Punjab and Haryana High Court by writ. Employees of a body that has not been notified, including many cooperative societies and some autonomous institutions, file a writ petition in the High Court; see writ petitions in the Delhi High Court.
If you are unsure, check whether your organisation appears in the notifications under section 14(2). The appointment letter and the service rules usually show who the appointing authority is, which often answers the question. Filing in the wrong forum costs months, so settle this before drafting anything.
Which CAT bench should you file in?
Rule 6 of the CAT (Procedure) Rules decides the bench: where you are posted, or where the cause of action arose wholly or partly. Retired, dismissed and terminated employees can also file where they ordinarily live.
| Your situation | Bench usually chosen | Note |
|---|---|---|
| Posted in Delhi, or order passed by a ministry in Delhi | Principal Bench, Copernicus Marg, New Delhi | Orders issued from New Delhi often give Principal Bench jurisdiction even for staff posted elsewhere |
| Posted in Noida or Ghaziabad | The bench covering western Uttar Pradesh (Allahabad Bench) | Check the territorial notification; the Principal Bench may also have jurisdiction if the order came from Delhi |
| Posted in Gurugram or Faridabad | Chandigarh Bench | Same point about orders passed in Delhi |
| Retired, dismissed or removed | Bench where you live at the time of filing, or the bench of your last posting | Rule 6(2) gives this option |
| Transferred after the order | Bench where the cause of action arose, or the new posting | Choose deliberately and explain jurisdiction in the OA |
The jurisdiction paragraph in your OA should say in one or two sentences why this bench can hear the case. A vague paragraph invites an objection from the respondents and an adjournment.
Must you exhaust departmental remedies before filing?
Ordinarily yes. Section 20 says the Tribunal will not ordinarily admit an application unless the applicant has used the remedies available under the service rules, such as an appeal against a penalty or a representation against a pay fixation. You are treated as having used them when the authority has passed a final order rejecting your appeal or representation, or when six months have passed since you filed it without any order.
The word 'ordinarily' matters. The Tribunal can admit an OA without waiting if the departmental remedy is futile, the order is plainly without jurisdiction, or urgent harm would be caused by waiting, for example a transfer order to be implemented in days or a recovery about to start from pension. You must explain why waiting is not possible, and the Tribunal will often still direct the authority to decide your representation within a short time instead of hearing the case itself.
Once the Tribunal admits your OA, section 19(4) says any pending departmental proceeding for redressal of the same grievance abates. So do not file an OA while hoping the department will also decide your appeal in your favour; the appeal stops.
What is the limitation period for a CAT application?
Section 21 sets one year. Where a final order has been passed on your appeal or representation, the year runs from that order. Where you made an appeal or representation and six months passed without a final order, the year runs from the end of those six months. So the latest date to file without asking for condonation is eighteen months after a representation that nobody answered.
Repeated representations do not restart the clock. If your first representation was rejected and you wrote again, and again, the year usually runs from the first rejection, not the latest reply. Departments sometimes send a fresh reply to a repeat representation that simply refers to the earlier decision; the Tribunal will normally treat that as no new cause of action. Count from the first real decision unless the later reply genuinely reconsidered the matter on its merits.
Some grievances are continuing wrongs: wrong pay fixation that reduces every month's salary, or pension paid at the wrong rate. For these the Tribunal may entertain an application despite delay, because each payment is a fresh cause, but it generally restricts arrears to a limited period before the date of filing, often about three years. The longer you wait, the more arrears you lose, even when the grievance itself survives.
How do you ask the CAT to condone delay?
File a separate miscellaneous application under section 21(3) along with the OA, supported by an affidavit, explaining the delay with dates. The Tribunal can admit an application after the period if it is satisfied that the applicant had sufficient cause. It looks at the length of the delay, the reasons, whether the applicant was diligent in between, and whether others' rights have settled in the meantime.
A good condonation application gives a short chronology: when the order was received, what you did next, any illness or posting to a remote place, any assurance from the department that the matter was being reconsidered, and when you took advice. Attach proof wherever possible, such as medical papers or a letter from the department. General statements that you were 'pursuing the matter with the department' persuade nobody without letters to show it.
Delay hurts most in seniority and promotion cases, because other employees have been promoted on the basis of the list you are challenging. The Tribunal is reluctant to unsettle long-standing seniority. In pay and pension cases, it is more lenient on the grievance but cuts the arrears.
Steps to file an Original Application
Collect the orders and your representations
Get copies of the order you are challenging, your appeal or representation, the reply (if any) and the relevant rules or office memoranda. If the department has not given you a copy of something it relied on, ask for it in writing or through RTI before drafting.
Fix jurisdiction, bench and limitation
Confirm that your employer falls within the CAT's jurisdiction, choose the bench under Rule 6, and calculate limitation under section 21. If you are out of time, prepare the application for condonation of delay at the same time.
Draft the OA in Form I
Write the application in the Form I sequence: particulars, order challenged, jurisdiction, limitation, facts, grounds, remedies exhausted, no other proceedings, reliefs and interim relief. Keep the facts in date order and the grounds tied to rules.
Prepare the paper book
Rule 4 asks for the application in triplicate, in two compilations: the first with the OA and the impugned order, the second with the other documents, paginated and indexed. Add extra sets for each respondent. Attested copies of the order are required.
Pay the fee and file
Pay the fee of ₹50 in the manner the bench accepts and file at the registry, or through the CAT's e-filing system where the bench uses it. Sign and verify the application, and attach a vakalatnama if an advocate is appearing.
Cure defects and get listed
The registry scrutinises the papers and returns them with any defects, such as missing pages, unattested copies or an incomplete index. Cure them quickly; the case is listed for admission only after that.
Admission hearing
At the first hearing the Bench decides whether to issue notice to the respondents, dismiss the OA, or dispose of it with a direction to the department. Interim relief is argued here. Be ready to explain jurisdiction, limitation and urgency in a few minutes.
When Advocate B.K. Singh prepares an OA, the paragraph he spends the most time on is the list of dates. A Bench reading a fresh application at admission usually turns to it first, and a clean chronology that shows the representation, the six-month wait and the filing date answers most of the questions about limitation before they are asked.

How to draft the Original Application
Form I sets out the structure, and the Tribunal expects you to follow it. After the particulars of the applicant and respondents, give the details of the order challenged (number, date, authority), then a jurisdiction paragraph, then a limitation paragraph. The facts come next in numbered paragraphs, in date order, each tied to an annexure. Then the grounds, each a separate lettered point. Then the remedies exhausted, a statement that the matter has not been filed and is not pending before any court or tribunal, the reliefs, and the interim relief.
Grounds win or lose an OA. Each ground should say which rule, office memorandum or principle the order breaches and how. 'The order is arbitrary and illegal' is not a ground. 'The order was passed without the show cause notice required by Rule 16 of the CCS (CCA) Rules, so it violates the principles of natural justice' is. Where you rely on a judgment, give its citation and the paragraph; a few well-chosen authorities are better than many.
The respondents should be the Union of India through the Secretary of the ministry or department concerned, and the officers who passed or must implement the order, by designation. In seniority and promotion cases, employees who would be affected if you win are necessary parties, and an OA without them can be dismissed for non-joinder. Name officers personally only where you allege mala fides, and then give facts.
Drafting mistakes that delay or sink an OA
- No clear prayer. Ask for specific relief: quash order number X dated Y, direct the respondents to grant pay in level Z from a date, with arrears and interest. A vague prayer produces a vague order that is hard to enforce.
- Skipping the representation. Filing without first making a representation, where one was available, invites a direction to represent and nothing more.
- Mixing causes of action. Two unrelated grievances in one OA lead to an objection and often to one of them being dropped.
- Leaving out affected employees. In seniority cases, the juniors who would lose are necessary parties.
- Not disclosing earlier litigation. If you filed an earlier OA or writ on a connected issue, say so. Concealment can lead to dismissal on that ground alone.
- Attaching unreadable copies. Faint photocopies of old service records cause defects at scrutiny and frustration at hearing. Get typed copies of key pages where needed.
Can the CAT grant interim relief at the first hearing?
Yes, but section 24 sets conditions. An interim order should ordinarily be made only after the respondents have been given copies of the application and documents and a chance to be heard. The Tribunal can dispense with this in an exceptional case for reasons recorded in writing, but such an ex parte interim order ceases after fourteen days unless the respondents have been heard by then and the Tribunal continues it.
So if you need protection urgently, serve an advance copy of the OA on the respondents' counsel or the departmental representative before the admission hearing, and file proof of service. That lets the Bench hear both sides at once and pass an order that lasts. Typical interim reliefs are a stay of a transfer not yet implemented, a stay of recovery from salary or pension, a direction not to fill a post or to keep a vacancy open, and a direction to allow the applicant to appear in a selection process provisionally.
The Tribunal grants interim relief where the applicant shows a prima facie case, that the balance of convenience favours relief and that refusal would cause harm money cannot make good. It is cautious about staying transfers and disciplinary proceedings, and more willing to stop recoveries or protect a vacancy. Ask only for what you need to keep the dispute alive.
What happens after notice is issued?
The respondents must file a reply within one month of service under Rule 12, though extensions are common. Their reply sets out the department's version and attaches its records. You can then file a rejoinder answering new facts in the reply; do not use the rejoinder to repeat the OA. After pleadings are complete, the case goes on the list for final hearing.
Hearings are generally before a Division Bench of a Judicial Member and an Administrative Member, though single-member benches hear certain categories under section 5(6). Arguments are usually short, focused on the documents and the rules. The Bench may ask the department's counsel to take instructions on whether the department will reconsider, and some matters are disposed of on that basis.
The time to decide an OA varies with the bench and the type of case. Cases with interim orders, retirement benefits or urgent transfers tend to move faster. Ordinary pay and seniority disputes can take longer. Keep track of the next date on the CAT website's case status page, and keep your counsel informed of any change in your posting or retirement, which can affect relief.
A made-up example: an unanswered representation on pay fixation
Here's a made-up example. Meena, an assistant in a central ministry in New Delhi, believes her pay was fixed wrongly on promotion in 2023, leaving her one stage lower than colleagues promoted at the same time. She makes a representation on 1 March 2025. No reply comes.
Six months pass on 1 September 2025, so under section 21 she has until 1 September 2026 to file without asking for condonation. She files an OA at the Principal Bench in July 2026, attaching the promotion order, the pay fixation statement, her representation with the receiving stamp, the comparison with two colleagues, and the office memorandum on fixation. Her prayer asks the Tribunal to direct re-fixation of pay from the date of promotion, with arrears.
At admission, the Bench issues notice. The department's reply admits the error for one colleague's batch but argues that her case is different. After her rejoinder points to the identical promotion order, the Tribunal allows the OA and directs re-fixation within three months. Because she filed within limitation, her arrears run from the date of promotion.
How much does a CAT case cost, and can you appear in person?
The court fee is low: ₹50 per application under Rule 7, and the Tribunal can waive it for an applicant who cannot pay. Other costs are photocopying, typing and the advocate's fee, which depends on the complexity and the number of hearings and is agreed separately. At our firm, fees are discussed at the first meeting and agreed in writing, stage by stage.
You can appear in person. Many applicants do, particularly in straightforward pension or pay cases. The difficulty for applicants in person is usually not the hearing itself but the drafting: limitation, the grounds and the prayer. A well-drafted OA argued by the applicant in person tends to do better than a poorly drafted one argued by counsel.
If your matter needs filing at a bench outside Delhi, the firm can arrange associate counsel there. The Tribunal also hears some matters by video, which helps where the applicant lives far from the bench.
After the CAT order: compliance, review, writ and contempt
If the OA is allowed, the order normally gives the department a time to comply. Send a copy of the order to the department with a letter asking for compliance. If it does not comply, the Tribunal has power under section 17 to punish for contempt, on the same footing as a High Court. A contempt petition usually produces compliance or an appeal, so the department's reply will show which way it is going. The general approach is explained in contempt petitions when an order is not followed.
A review application lies to the same Tribunal within thirty days of receiving the order under Rule 17, but only for an error apparent on the face of the record, new evidence that could not be produced earlier, or a similar sufficient reason. It is not a second hearing. If you think the Tribunal was simply wrong, the remedy is a writ petition before a Division Bench of the High Court, as settled in L. Chandra Kumar v Union of India (1997).
From the High Court, the next step is a special leave petition in the Supreme Court within ninety days; see special leave petitions. The department often challenges CAT orders in the High Court too, so a win at the Tribunal does not always end the matter; keep your papers in order for the next round.
What to do this week if you plan to file an OA
- Gather the order you want to challenge and every representation, appeal and reply
- Write down the date you received each order and each reply
- Count one year from the final order, or eighteen months from an unanswered representation
- Check whether your employer is within the CAT's jurisdiction
- Choose the bench under Rule 6, especially if you have been transferred or have retired
- List the colleagues who would be affected if you win (seniority and promotion cases)
- Ask for missing records in writing or through RTI; see RTI applications and appeals
- If something is about to happen (transfer, recovery, selection), prepare the interim relief request and an advance copy for the respondents
When to take advice on a CAT matter
Advice is most useful before filing: on jurisdiction, limitation and the grounds, because those decide whether the OA reaches a hearing on merits. It is also useful when the department's reply raises a rule or a precedent you did not expect, and after the order, when deciding whether to seek review, go to the High Court or simply press for compliance.
Advocate B.K. Singh appears before the CAT Principal Bench and the Delhi High Court in service matters; his background is described on his profile page. If you want the order and your representation read before you decide whether to file, send them through the online enquiry form and the team will tell you the limitation date and the likely forum.
Frequently asked questions
What is the fee for filing an OA in the CAT?
Rule 7 of the CAT (Procedure) Rules 1987 fixes a fee of ₹50 per application. The Tribunal can waive it if the applicant cannot pay. Advocate fees and copying costs are separate.
Can I file an OA in the CAT without a lawyer?
Yes. Section 23 of the Administrative Tribunals Act allows the applicant to appear in person. The drafting of limitation, grounds and reliefs is where most applicants in person need help, so consider advice on the draft even if you argue yourself.
What is the limitation for filing in the CAT?
One year from the final order on your appeal or representation, or one year after six months have passed without a decision, under section 21. Delay beyond that can be condoned on an application showing sufficient cause.
Do repeated representations extend limitation in the CAT?
Generally no. The year usually runs from the first decision rejecting your representation. A later reply that merely refers to the earlier decision does not create a fresh cause of action.
Where is the CAT Principal Bench in Delhi?
The Principal Bench sits at Copernicus Marg, New Delhi. It hears service matters of employees posted in Delhi and cases where the order was passed in Delhi, along with matters assigned to it by law.
Can Delhi government employees file in the CAT?
Yes. Employees of the Government of NCT of Delhi and Delhi Police take their service disputes to the CAT Principal Bench. Employees of bodies not notified under section 14(2) of the Act go to the High Court instead.
Can a retired employee file an OA where he lives?
Yes. Rule 6(2) of the CAT (Procedure) Rules allows retired, dismissed or terminated employees to file at the bench where they ordinarily live when they file. They can also file at the bench of their last posting.
What happens to my departmental appeal if I file an OA?
Once the Tribunal admits your OA, section 19(4) says any pending departmental proceeding for redressal of the same grievance abates. Decide whether to wait for the appeal or go to the Tribunal, not both.
How long does the department get to reply to an OA?
Rule 12 gives the respondents one month from service of notice to file their reply. The Tribunal often allows more time on request. You can file a rejoinder after the reply.
Can several employees file one application in the CAT?
Yes, with the Tribunal's permission, where they share the same grievance and cause of action. An association can also file for its members if at least one affected member joins the application.
How do I challenge a CAT order?
By a writ petition before a Division Bench of the High Court having jurisdiction over that bench, following L. Chandra Kumar v Union of India (1997). A review application to the Tribunal within thirty days is available only for errors apparent on the record.
What if the department does not follow the CAT order?
Write to the department with a copy of the order first. If it still does not comply within the time given, file a contempt petition before the Tribunal under section 17. The department will usually comply or file a challenge.
