In short. An additional affidavit in the tribunal is how you place a document on record that you did not have, or did not need, when your OA was filed: an RTI reply, a later order, or a paper that answers the department's reply. It is filed with a short application asking the bench's leave, and the bench decides whether to take it on record. The process usually takes two to six weeks. Start by checking how and when you got the document, because the bench will ask why it was not filed earlier.
Is this your situation?
- An RTI reply arrived after your OA was filed and it contains the DPC minutes or noting you had been asking for.
- The department's reply says you were informed of something, and you have a letter or email proving otherwise.
- A new order was issued after filing, such as a recovery notice, a pension sanction or a junior's promotion, and the bench should know about it.
- You found an old office order in your papers that you forgot to annex.
- Your counsel says a document is 'not on record' and cannot be relied on at the hearing.
- You want to know whether to file a rejoinder, an additional affidavit or an amendment.
In short
- New material needs the bench's permission. A paper filed after the OA without leave can be kept out of the record under the CAT Rules of Practice.
- Explain the timing honestly. Say when you received the document and why it could not be filed with the OA; an RTI reply with a date is the cleanest explanation.
- Facts by affidavit, new claims by amendment. An additional affidavit brings facts and documents; a new relief or a challenge to a new order needs an amendment of the OA.
- The department gets to answer. Expect the bench to allow the respondents time to respond to whatever you add.
- Judgments and government orders rarely need an affidavit. Those can usually be handed up in a compilation at the hearing.
When an additional affidavit is the right tool
An additional affidavit in the tribunal is a sworn statement, filed after your OA, that places new facts or documents before the bench. You use it when something relevant has come into existence or into your hands after filing, and the case cannot be fairly decided without it.
Three situations account for most of these filings in service cases. The first is an RTI reply that arrives late: you applied for the DPC minutes, the inquiry file or your APARs before filing, the information came months later, and it supports your case. The second is a document that answers something the department said in its counter reply, for example the department claims a memo was served and you hold the returned envelope. The third is a later development that bears on relief: you have since retired, or the department has started recovery, or a junior has been promoted against the vacancy you claim.
It is also used when a document was simply missed at the time of filing. That happens more often than people admit, especially when the OA was prepared in a hurry to beat limitation. Benches are usually tolerant of this if the document is relevant and the request comes early, well before final hearing.
What an additional affidavit is not for is a fresh argument, a new prayer or a challenge to a fresh order. Those belong in an amendment, which follows a different process.
Which route fits which kind of new material
| What you now have | Usual route | Why this route |
|---|---|---|
| RTI reply or record proving a fact already pleaded | Additional affidavit with an MA for leave | It supports what the OA already says; nothing new is claimed |
| A paper that answers the department's reply | Rejoinder, with the paper annexed | The rejoinder is the natural place to answer the reply, if time for it has not run out |
| A fresh order that changes or replaces the one challenged | Amendment of the OA | A new decision needs its own grounds and prayer |
| A later DoPT, DoE or DoPPW office memorandum | Compilation at the hearing, or a short note | Government orders are public; the bench can read them without an affidavit |
| A Supreme Court or High Court judgment | List of authorities at the hearing | Law is argued, not proved by affidavit |
| A document only the department holds | Application for production of records | The bench can direct the department to produce the original file |
| A change in your personal status, such as retirement or death | Additional affidavit, or an application to bring legal heirs on record | The bench must know who is now entitled to relief |
What the rules say about documents after filing
The CAT (Procedure) Rules, 1987 deal with documents mainly at the start of the case. Rule 9 lists what must accompany the OA, including copies of the documents you rely on. Rule 12 does the same for the department's reply. There is no separate rule that spells out an applicant's right to add documents later, which is why leave of the bench is the safe course every time.
Two other provisions fill the gap. Rule 12(6) lets the tribunal permit amendment of pleadings in the manner of Order VI Rule 17 of the Code of Civil Procedure. And Section 22(3) of the Administrative Tribunals Act gives the tribunal the powers of a civil court for specific purposes, including requiring discovery and production of documents and receiving evidence on affidavits.
The CAT Rules of Practice, 1993 are more direct. They define 'pleadings' to include additional statements supplementing an application or reply, but only as permitted by the tribunal. They also provide that additional pleadings filed without leave, or after the time granted, are kept out of the case record and returned. In plain terms, if you simply walk into the registry with a fresh set of papers, they may never reach the judges.
Benches do not apply these rules mechanically. A short, relevant document filed promptly with a proper application is almost always taken on record. The rules come into play when a party tries to add bulk material late, or without explanation, or in a way that would take the other side by surprise.
How an additional affidavit is filed, step by step
The sequence below is the usual one at most benches. Your counsel may combine some steps.
Sort what is genuinely new and relevant
Go through what you have received and keep only what proves a fact in issue. Ten pages that matter are better than a hundred that bury the point. If a document only repeats something already annexed, leave it out.
Note the date and source of each document
Write down when and how you received each paper: an RTI reply dated 14 August, a letter received by post on 2 September, an order downloaded from the department's website. That timeline becomes the explanation for lateness.
Prepare an MA seeking leave
A miscellaneous application asks the bench to permit the additional affidavit and take the documents on record. It states the stage of the case, what the documents are, why they matter and why they were not filed earlier. Our page on miscellaneous applications in a pending OA covers the form and fee practice.
Draft the affidavit itself
The affidavit sets out the new facts in short numbered paragraphs and annexes the documents, continuing the annexure numbers from your OA. It ends with a verification and is sworn before an oath commissioner or notary as your bench requires.
Serve the other side
A copy of the MA and affidavit goes to the standing counsel for the respondents, and to any private respondent such as a junior whose seniority is in issue. Keep proof of service.
Get it listed and argue leave
The MA is listed with the OA or separately. Often the bench allows it in a minute. If the department objects, be ready to show relevance and the reason for delay.
Allow the department to respond
If leave is granted, the bench will usually give the respondents a few weeks to reply to the affidavit. Factor this into your expectations of when the case will be heard.
What to write in the affidavit, and what to leave out
Open by identifying yourself and the case, and say that the affidavit is filed to place certain documents on record with leave sought by the accompanying application. Then, document by document, say what it is, its date, how you came to have it, and which paragraph of the OA or the reply it relates to. That last link matters: the bench reads the affidavit alongside the main pleadings, and a direct cross-reference saves it from hunting.
Keep the language factual. An affidavit is evidence, not argument. 'The RTI reply dated 14.08.2026 at Annexure A-15 shows that only two officers were considered by the DPC held on 03.03.2025' is a fact. 'This shows the blatant illegality of the respondents' is argument, and it belongs in your written submissions.
Do not add new grounds, new reliefs or allegations of mala fides through an additional affidavit. If the new document reveals something that needs a new prayer, say so to your counsel; the right tool is amendment. A bench that sees new grounds smuggled into an affidavit may refuse to look at the affidavit at all.
Make sure the verification is correct. Distinguish between what you state from personal knowledge and what is based on records, and mark the documents as true copies. Our guide on vakalatnama, verification and affidavit in a tribunal filing explains the wording benches expect.
Why the bench asks why you did not file it earlier
Every additional document filed late raises one natural question from the bench: where was this when you filed the OA? The answer decides whether the document goes on record easily, with costs, or not at all.
The strongest answer is that the document did not exist, or you did not have it, at the time of filing. An RTI reply with a date, a letter with an envelope postmarked after filing, or an order dated later than the OA all answer the question themselves. If you obtained a document after filing, say so plainly and attach the covering letter.
A weaker but still common answer is oversight. If the document was always in your possession, admit it. Benches respond better to a frank 'this was inadvertently not annexed' than to a vague claim that it was 'recently traced'. If the case is at an early stage, oversight is usually forgiven, sometimes with a small cost. If the case is at final hearing, the bench will ask whether the document is really necessary.
Where the department itself held the document and refused to share it, say that too, with the dates of your requests. That turns the delay into a point against the department, and it may support a request for costs or adverse inference.
Supplementary affidavit, rejoinder or amendment: telling them apart
People use these terms loosely, and the registry sometimes does too. The differences matter because each has its own purpose and timing.
A rejoinder is your answer to the department's reply. Under the CAT Rules of Practice it is filed with leave of the bench or the Registrar, within the time allowed, and once that time expires the case is treated as ready for hearing. If you have a document that rebuts the reply and the rejoinder is still due, annex it there. That is simpler than a separate affidavit.
A supplementary or additional affidavit brings in facts and documents at any later stage with leave. It is the flexible tool for material that arrives after pleadings close, or that has nothing to do with the reply.
An amendment changes the OA itself: its facts, grounds or reliefs. You need it when a new order replaces the one you challenged, when you must add a party, or when you want relief you did not originally ask for. Our guide on amending your OA after a new order is passed deals with it in detail. If you are not sure which one fits, the table above is a reasonable first test.
Advocate B.K. Singh's two tips on late documents
The first tip from Advocate B.K. Singh is about presentation. He continues the annexure series from where the OA paper book ended, so if your OA closed at Annexure A-14, the additional documents start at A-15, and the page numbers continue too. He also adds a one-page index on top. A bench reading the case months later can then find the new paper in seconds, instead of wondering whether 'Annexure 1' means the first annexure of the OA or of the affidavit. Our guide on putting the OA paper book in order explains the system he follows.
The second tip is about where the document came from. Advocate B.K. Singh asks every client how they obtained a document before it goes on record. A copy obtained through RTI, received officially, or certified by the department is safe. A photocopy of a confidential file passed on informally by a colleague is a different matter: it may raise questions under the CCS (Conduct) Rules for you or for the colleague. In that situation he usually prefers to ask the bench to call for the original record from the department, which achieves the same end without the risk.
Documents the department holds: asking the bench to call for them
Many service cases turn on a file you will never see unless the bench orders it: DPC minutes, the review committee note in a suspension case, the vigilance clearance status, the file noting behind a recovery. RTI may get you some of it, though personal information exemptions have tightened since November 2025 (check the current position on Section 8(1)(j) of the RTI Act).
Where RTI fails or would take too long, apply to the bench for a direction to the respondents to produce the relevant record. Section 22(3) of the Administrative Tribunals Act empowers the tribunal to require discovery and production of documents and to requisition public records. Benches often direct that the original file be produced at the hearing, sometimes in a sealed cover.
Be specific. Identify the file by its subject, the date of the meeting or order, and the office that holds it, and explain in two lines why it is needed. A request for 'all records relating to the applicant' is likely to be refused as a fishing exercise.
Our guide on RTI for DPC minutes, APARs and inquiry files covers what RTI tends to yield and what it does not, which helps you decide which route to try first.
New documents that commonly turn up, by type of case
For retirees and family pensioners, the most common late document is the PPO or revised PPO, issued after the OA was filed, which shows the department's actual calculation. It may partly grant your claim, which changes what remains in dispute, or it may confirm the error you alleged. Either way the bench should see it.
For serving employees in promotion and seniority cases, it is usually the promotion order of a junior, a final seniority list issued after a tentative one, or an APAR disclosed late. In disciplinary cases, it is often the inquiry report or the penalty order itself, if the OA was filed at the chargesheet stage. A penalty order is a new decision, though, and normally calls for amendment rather than an affidavit.
For candidates in recruitment cases, the late documents are the final answer key, the merit list, the cut-off marks or the result of a medical review board. Recruitment cases move fast, and a document that changes your rank needs to be on record before the bench decides whether to hold a post for you.
For railway and postal staff, departmental circulars and divisional orders are often the missing link. These may be on the department's website or in the office's guard file, and an additional affidavit is the right way to bring a specific one before the bench when it is not otherwise easy to find.
Filing an additional affidavit at your tribunal bench
Your additional affidavit is filed at the same bench as your OA. That bench was chosen under Rule 6 of the CAT (Procedure) Rules, usually by where you are posted or where the cause of action arose, or, for retirees, where you now live. If the case was transferred to another bench under Section 25, the filing goes there.
Most benches now accept e-filing through the CAT portal, and many expect a paper set as well. The CAT circular of 21 October 2026 on uniform filing practices, as reported, calls for bookmarked and searchable PDFs, which matters for a document-heavy affidavit. Ask your bench registry how many paper sets they need and whether the MA and affidavit can be uploaded together.
Registries often raise objections on small points: missing page numbers, an unsigned verification, a document in Hindi or a regional language without a translation, or a fee not paid on the MA. Our guide on curing filing defects and registry objections lists the usual ones. A defect can delay listing by two or three weeks, so check before filing.
If a document is in a language other than English or Hindi, attach a typed English translation with a short note on who translated it. Benches outside the Hindi belt may ask for an English translation even of Hindi papers.
A made-up example: a CPWD junior engineer in Karnal and DPC minutes that came by RTI
Here's a made-up example. Harpreet, a junior engineer in a CPWD division at Karnal, was passed over for promotion as Assistant Engineer. He filed an OA before the Chandigarh Bench, alleging that an APAR graded below benchmark had never been communicated to him. He had applied under RTI for the DPC minutes three weeks before filing, but the reply had not come.
The department's reply, filed five months later, stated that all APARs had been 'duly disclosed'. Two weeks after that, the RTI reply finally arrived. It included the DPC minutes and, in the annexed APAR dossier, a disclosure column left blank for the year in question.
His counsel filed an MA for leave with an additional affidavit, annexing the RTI application, the covering letter dated after the reply was filed, and the relevant pages of the minutes as Annexures A-11 to A-13. The affidavit referred specifically to the paragraph of the reply that claimed disclosure.
The department asked for time to respond, which was allowed. Its short reply did not explain the blank column. The point for readers is the order of events: because the RTI dates were documented, nobody questioned why the minutes came late, and the affidavit went on record at the first listing. The outcome of the OA depended on many other things, but the key fact was no longer one person's word against another's.
What to bring to your counsel before an additional affidavit is drafted
The new material
- Each new document, in the clearest copy you have
- The covering letter, envelope or email that shows when it reached you
- Your RTI application and first appeal, if the document came through RTI
- A typed translation for any document not in English or Hindi
The case papers
- Your OA paper book as filed, with its last annexure number and page number
- The department's reply and your rejoinder, if filed
- The latest order sheet, to know the stage of the case
- Any earlier MA in the same case, so numbering and facts stay consistent
A short note from you
- One line per document saying what it proves
- The paragraph of the OA or reply it relates to
- Whether anyone else gave you the document, and how
Time and cost for an additional affidavit
| Stage | Typical time | Cost in general terms |
|---|---|---|
| Collecting and sorting documents | A few days to a few weeks, longer if RTI is pending | RTI fee of Rs 10 per application at the Centre, plus copying charges |
| Drafting the MA and affidavit | One to two weeks | Notary or oath commissioner charges, typing and copying |
| Filing and registry scrutiny | A few days to two weeks | A small court fee on the MA where the bench charges one; check with the registry |
| Listing and decision on leave | Next date of the OA, or two to six weeks if listed separately | Occasionally a small cost if the delay in filing is unexplained |
| Department's response to the affidavit | Three to six weeks | Nothing for you |
| Effect on final hearing | May push the hearing back by one or two listings | Your counsel's fee for the additional work, agreed in writing beforehand |
Mistakes that get late documents refused or ignored
The most common mistake with additional documents in an OA is filing without leave, by simply handing papers to the registry. They may sit outside the record, and at the hearing the department's counsel will rightly object that they were never permitted. Always file the MA with the affidavit.
The second is filing too much. A thick bundle of loosely related papers makes the bench suspect that the important document is being hidden, or that the case lacks focus. Keep only what proves a specific fact in issue.
The third is filing at the last moment. An additional affidavit served the day before final hearing almost guarantees an adjournment, because the department must be allowed to answer it. If the document has been with you for months, the bench may refuse it outright. Our guide on the department not filing its reply describes how adjournments and costs work when the other side is late; the same discipline applies to you.
The fourth is using the affidavit to argue. Adjectives, accusations and legal submissions weaken a document meant to state facts. Save the arguments for your written notes at the final hearing.
What to do this week
List every document you have received since your OA was filed, with the date you got it and a one-line note on what it shows. Then check the case stage on the order sheet. If the rejoinder is still due, the simplest course may be to annex the documents there. If pleadings are complete, an additional affidavit with an MA for leave is the route, and the sooner it is filed the less it will delay the hearing.
If the document you need is with the department and RTI has not worked, write down exactly which file or meeting you need, so an application for production can be precise. For an overview of the applications that can be filed in a pending case, see our page on miscellaneous applications in a pending OA. If your OA has not yet been filed, include everything at the start; our page on filing an Original Application under Section 19 explains what goes in.
If you have new documents and are unsure which route fits, you can reach Advocate B.K. Singh for a view on your documents or for news of changes in tribunal practice.
Frequently asked questions
Can I file new documents in CAT after my OA is filed?
Yes, with the bench's leave. File a short miscellaneous application with an additional affidavit annexing the documents, and explain when and how you received them.
What happens if I file papers without permission?
The CAT Rules of Practice allow the registry to keep additional pleadings filed without leave out of the case record. They may be returned, and the bench may not look at them at the hearing.
Do I need an affidavit to rely on a new DoPT order or a Supreme Court judgment?
Usually not. Government orders and judgments can be handed up in a compilation or a list of authorities at the hearing, since they are law or public instructions rather than facts to be proved.
Is an additional affidavit the same as a rejoinder?
No. A rejoinder answers the department's reply and is filed within the time allowed for it. An additional affidavit brings new facts or documents at any later stage, with leave.
Will the department get to reply to my additional affidavit?
Generally yes. Benches allow the respondents a few weeks to respond, which is why filing early matters.
Can I challenge a new penalty order through an additional affidavit?
No. A fresh order that you want set aside needs its own grounds and prayer, which means amending the OA or, in some cases, filing a new one.
My RTI reply came after the department's reply was filed. Is it too late?
Not necessarily. If the case is not yet at final hearing and you can show the RTI dates, benches usually allow such documents on record, sometimes with a short time for the department to answer.
Who swears the additional affidavit if the applicant has died?
Once the legal heirs are brought on record, one of them can swear it on the basis of records. The substitution application usually comes first.
