In short. Yes, several employees can file one Original Application before the Central Administrative Tribunal, but only with the tribunal's permission under Rule 4(5) of the CAT (Procedure) Rules. The bench allows it when everyone is challenging the same order or rule and wants the same relief. A short application seeking that leave goes in with the OA, and the filing fee is charged once. Each person's time limit is still checked on its own. If colleagues share your grievance, collect every person's order and representation before deciding who joins.
Is this your situation?
- One circular or office order has cut the pay, MACP or allowance of a whole group of you.
- Your entire recruitment batch has been pushed down in a single seniority list.
- Your staff association wants to challenge a rule on behalf of its members.
- Several pensioners from the same office have received the same recovery notice.
- Candidates from one recruitment were all rejected for the same reason.
- Some colleagues want to file now while others want to wait and watch.
- You are not sure whether an order won by colleagues years ago covers you too.
Yes, you can file together, but the tribunal has to agree
The CAT (Procedure) Rules, 1987 are built on the idea that one person files one application about one grievance. Rule 4(5) is the exception. The tribunal may let more than one person join and file a single Original Application if, looking at the cause of action and the relief asked for, it is satisfied that they share a common interest. This permission is not automatic. You ask for it through a short miscellaneous application filed along with the OA, and the bench decides it at the admission stage, usually on the first date of listing.
Benches grant it without much fuss when the facts are plain: one office order, one stated reason, many names. Think of a circular withdrawing an allowance from all Group C staff of a regional office, a seniority list that drops an entire batch below promotees, or a recovery raised against forty pensioners on the same audit para. Benches become wary when each applicant's story needs separate examination, because a joint OA then turns into forty small cases stitched into one file.
A joint OA is also different from a public interest petition. The Supreme Court has said more than once, including in Hari Bansh Lal v. Sahodar Prasad Mahto (2010), that PIL is not the way to raise service grievances. The people affected have to come forward themselves, either one by one or together under Rule 4(5).
The rules that govern a joint application
Rule 4(5)(a), CAT (Procedure) Rules, 1987
Allows the tribunal to permit two or more persons to file one application where, having regard to the cause of action and the relief sought, they have a common interest in the matter. The word used is 'may', so it is the bench's discretion. Your application for leave should show why the facts are common rather than just say so.
Rule 4(5)(b), CAT (Procedure) Rules, 1987
Extends the same permission to an association representing the persons who want to join. Two conditions come with it. The application must disclose the class, grade or category of persons on whose behalf it is filed, and at least one person who is actually affected must join as an applicant along with the association.
Rule 7, CAT (Procedure) Rules, 1987
Prescribes a small fixed fee for an application (Rs 50 under Rule 7; check the current figure and mode of payment with the registry). The first proviso says that where a single application by several persons or by an association is permitted, the fee is still the single fee. The second proviso lets the tribunal exempt an applicant who cannot pay because of indigence.
Rule 6, CAT (Procedure) Rules, 1987
Tells you which bench to approach: the one covering your present place of posting, or the one in whose area some part of the grievance took place. Pensioners and people who were dismissed or terminated get a third choice, the bench covering the town they now live in. In a joint OA, check this for every single applicant.
Sections 19, 20 and 21, Administrative Tribunals Act, 1985
Section 19 gives each person aggrieved by an order the right to apply. Section 20 expects departmental remedies to be tried first, and Section 21 sets the one-year limit. None of these is relaxed because people come together. Each one applies to every applicant separately.
Common interest: the question the bench really asks
The test boils down to this: if the tribunal decides the point for one applicant, has it decided it for all of them? When the answer is yes, a joint OA saves time for the bench and for the department, and there is little reason to refuse it. When the honest answer is 'that depends on each person's record', expect to be told to file separately.
Common interest usually rests on one of three things. All the applicants are hit by the same order, such as one office order refixing pay for a list of named staff. Or they are hit by the same rule or instruction, applied to each through separate letters that say the same thing. Or they belong to one class whose position is fixed by one document, such as a seniority list or a select list. The relief must also be of the same kind: setting aside the same order, granting the same pay level, or redrawing the same list.
Differences in amount do not matter. Twenty pensioners will have twenty different recovery figures, and that is fine because the reason for the recovery and the legal objection are shared. Differences of fact that change the answer do matter. If one applicant signed an undertaking at the time of pay fixation and the others did not, or one was on extraordinary leave on the cut-off date, the department will build its reply around that person. The bench may then decide the common point and leave the odd case hanging, or it may ask the whole group to split.
Which grievances usually suit a group OA
| Kind of grievance | Fit for one joint OA? | Why |
|---|---|---|
| MACP or pay level refused to a whole cadre on one reading of a rule | Generally yes | A single legal question; the arithmetic differs but the answer does not |
| An allowance stopped by one circular for a class of staff | Generally yes | Same order, and every applicant wants it restored |
| Recovery of excess pay from many retirees on one audit objection | Mostly | Shared ground, though anyone who gave an undertaking may need separate handling |
| A seniority list that places one batch below another group | Mostly | One class affected; the gaining group must be made respondents |
| Candidates disqualified over the same answer key or eligibility reading | Mostly | One recruitment and one reason, provided all approached in time |
| Transfers of several people to different stations | Seldom | Each posting turns on its own grounds and the office's needs |
| Penalties in separate disciplinary cases on similar charges | Seldom | Each inquiry record has to be read on its own |
| Downgraded APARs of several officers | No | Each grading depends on one officer's reports and representation |
One order with many names, or one rule applied many times
The easiest joint OA is the one where a single order carries all the names. You challenge that one order, annex it once, and the relief writes itself. When the department has instead issued thirty separate letters with identical wording, you annex one specimen, describe it as representative, and add a chart listing each applicant with the number and date of his or her own letter. Benches accept this regularly. What they do not like is a pile of thirty identical annexures that adds pages and nothing else.
A related situation arises in discipline. Where the department itself held a common inquiry against several employees under Rule 18 of the CCS (CCA) Rules, 1965 and passed penalties on the same findings, a joint challenge is sometimes allowed, because the inquiry record is one. Benches differ on this, and where the penalties differ in kind or the defences took different lines, separate OAs heard together are usually safer.
Recruitment cases fall somewhere in between. Twelve candidates rejected because the commission read 'equivalent qualification' narrowly share a common interest. Twelve candidates rejected for twelve different document defects at verification do not, even if they all feel equally wronged.
When the staff association is the applicant
Rule 4(5)(b) lets an association file on behalf of a class of employees, but only if at least one affected person joins as a co-applicant and the OA states the class, grade or category being represented. Without the affected member, the association has no grievance of its own to bring. Departments often object that the association is unregistered or unrecognised, so keep its registration certificate, bye-laws, any recognition letter under the CCS (Recognition of Service Associations) Rules, 1993, and a resolution authorising the case and naming the office-bearer who will sign.
The practical gain of an association OA is that members who are not named may still get the benefit if the relief clause asks for it to be extended to everyone in the disclosed category. The risk is the opposite reading: the department may later argue that only the named applicants are entitled. Draft the relief with that argument in mind. Our page on whether a union or association can file a service case covers standing in more detail.
One caution that groups overlook: an association cannot speak for both sides of a dispute. In a promotee versus direct recruit seniority fight, members of the same association often stand on opposite sides. Filing in the association's name then invites an objection that it does not represent the class, and it can split the membership.
Each applicant's one-year clock runs separately
Joining a group does not revive anyone's expired claim. Section 21 gives each person a year from the final order. Where someone appealed or represented and heard nothing, the department gets six months to answer and the year starts after that, so the outer limit for that person is about eighteen months from the date the representation went in. If twelve of fifteen colleagues are within time and three are not, those three need their own application for condonation of delay under Section 21(3), supported by an affidavit as Rule 8(4) requires, explaining their own reasons. The bench may admit the OA for the twelve and delete the three.
Claims about pay fixation and pension are treated as continuing wrongs, so limitation is applied less strictly to them. Arrears are another matter. For pay, the tribunal commonly limits arrears to about three years before the date of filing. For pensions, the Supreme Court refused to apply that cap in Maya Banerjee v. Union of India (2026), so the position is less settled than it was; check the current law before telling the group what they can expect.
Repeated representations do not stop the clock, as the Supreme Court held in S.S. Rathore v. State of M.P. (1989). Groups lose time most often while waiting for the association's meeting with the department to produce something. See our page on filing late with a Section 21 application if some of your colleagues are already outside the year.
The representation stage when many people are affected
Section 20 expects each applicant to have tried the departmental remedy first. A joint representation signed by every affected person is usually accepted as meeting this, provided it was sent through proper channel to the authority competent to decide it (DoPT's instructions of 6 June 2013 on representations warn against going over the heads of your own office). A letter from the association alone may not count as each member's representation, so it is safer for every person to sign, or to send a short individual covering letter that adopts the common one.
Once the representation has gone, the department has six months. If it rejects the representation in one letter for everyone, that letter is the final order for all of you and the year runs from it. If it stays silent, the year runs from the end of the six months. When the OA is admitted, Section 19(4) treats any pending departmental proceedings on the same grievance as abated, so do not expect a reply to the representation to arrive and help you after filing. Our page on the representation Section 20 expects explains how to frame it.
Which bench, when the group is spread across stations
Rule 6 asks where each applicant is posted and where the cause of action arose. If all the applicants work in one city, the bench for that city is the obvious place. When they are spread out, say staff of one service posted in Chennai, Bhopal and Guwahati who are all hit by a ministry order issued in New Delhi, part of the cause of action arose in Delhi and the Principal Bench in New Delhi can usually hear them together. Each applicant could also file at his or her own bench, which risks three different answers to one question.
Pensioners can use their home town under Rule 6(2), which suits a retirees' group whose members have moved back to their districts. That rule does not help a serving member posted in Pune join a group filed in Patna over an order that has nothing to do with Patna. Two further routes exist. The Chairman can allow filing at the Principal Bench under the proviso to Rule 6(1), and under Section 25 the Chairman can shift a pending case between benches, which is one way to get similar OAs heard in one place. See moving a pending case to another bench.
Choosing a bench has a second effect people forget: it also decides which High Court will hear a writ if either side is unhappy with the result. That follows from L. Chandra Kumar v. Union of India (1997), and in Alapan Bandyopadhyay (2022) the Supreme Court made clear that a writ against a Principal Bench order belongs in the Delhi High Court.
Building a joint OA, from the first meeting to admission
The order below is how a group case usually comes together. Skipping the screening step is where most trouble starts.
Write the common point in one sentence
Before anyone collects papers, agree on the single question all of you want answered, for example 'the second MACP should run from the date of completing 20 years, not from the date of the screening committee'. If the group cannot agree on one sentence, it may need two OAs.
Screen each person who wants to join
For every applicant, note the post, place of posting, date of the order against him or her, date of representation and any reply. Ask whether anyone signed an undertaking, has a past case on the same point, or is under a penalty or inquiry. Anyone whose facts differ in a way that changes the answer should file separately.
Get consent and authority in writing
Each applicant signs the vakalatnama and a short consent stating that he or she joins the OA, has read the facts relating to him or her, and agrees to the arrangement on costs and instructions. Many registries want every applicant's signature on the vakalatnama; check your bench's practice before filing.
Draft the OA with an applicant chart
The OA narrates the common facts once and then refers to a chart giving each applicant's details. The relief clause should say clearly who gets what, and should ask for the benefit to be extended to all applicants by name. Grounds should deal with any differences the department is likely to raise.
File the Rule 4(5) application with the OA
A short miscellaneous application explains why the applicants share a common interest and asks leave to file jointly. If any applicant is late, a separate delay application with affidavit goes in for that person. The single fee is paid for the OA, subject to the current rule and practice of the registry.
Admission, notice and the first order
On the first date, the bench considers the joint filing application, decides whether to issue notice and may consider interim relief if asked for. It may allow the joint OA for some applicants and direct others to file their own cases.
Keep the cause title accurate while the case runs
Applicants retire, move, die or lose interest during a long case. Each change needs an application: deleting a name, bringing a legal heir on record, or recording a new address. Ignoring these leaves gaps the department can use at the compliance stage.
Advocate B.K. Singh usually spends more time on step two than on the drafting. One applicant with a different service history can turn the department's reply into an argument about that one person and delay everyone else.
Papers to collect from each applicant and for the group
From every applicant
- The order affecting him or her, or the letter applying the common order
- Copy of the representation with the diary number or receipt
- Any reply received, even a one-line rejection
- A recent pay slip, or PPO for retirees, showing the effect of the order
- Proof of current posting, or residence for retirees
- Signed vakalatnama and a short written consent to join
- A note on any earlier case, undertaking or pending inquiry
For the group as a whole
- The circular, rule or seniority list under challenge
- Any order granting the same benefit to similarly placed staff elsewhere
- A master chart with names, posts, dates and amounts
- RTI replies or file notings that explain the department's reasoning
If an association is filing
- Registration certificate and bye-laws
- Recognition letter, if any
- Resolution authorising the OA and naming the signatory
- Description of the class or grade represented
- Full papers of at least one affected member who joins as co-applicant
How long a group case takes and what it costs, in general terms
| Stage | Usual time range | What you pay for |
|---|---|---|
| Collecting papers from every applicant | Two to six weeks; longer if retirees live in different states | Copies, courier and attestation for each person |
| Drafting the OA, chart and Rule 4(5) application | One to three weeks once papers are complete | Professional fee, agreed in writing at the outset and shared as the group decides |
| Filing and registry scrutiny | A few days to a couple of weeks, depending on objections | One small fixed tribunal fee for the permitted joint OA (Rs 50 under Rule 7; confirm the current amount) |
| First listing and notice | Often within a few weeks of a clean filing | No further tribunal fee; appearance on the date |
| Reply and rejoinder | Commonly two to six months, sometimes longer | Rejoinder drafting; fresh affidavits if new facts surface |
| Final hearing and judgment | Differs a great deal between benches; a year or more is not unusual | Hearing preparation and certified copies |
| Compliance, contempt or writ | Department gets the time set in the order; a writ can add a year or more | Engaged separately for that stage |
Running a group: coordinators, costs and decisions in writing
A group of twenty-five needs two people who speak for it, collect papers and pass on instructions. Lawyers cannot take conflicting instructions from different members on the same day, and the bench will not wait while a group argues on a WhatsApp chat. Agree at the start who decides on routine matters such as adjournments, and what needs everyone's consent, such as withdrawing the OA or accepting a partial offer from the department.
Fees for a group case are discussed at the first meeting and agreed in writing, stage by stage, like any other case. How the group divides that cost among its members is for the group to settle, and it should be written down before filing. The usual friction point is the member who stops contributing after two years but still expects the benefit. Decide in advance what happens then.
Each applicant should also understand that his or her own facts are stated in the OA and verified. If a member's posting, pay or date of representation is wrong in the chart, correct it before filing rather than after the department points it out.
When winning for the group means someone else loses
A group asking for seniority, promotion or a share of posts is almost always asking for something that will come out of another group's position. Those people must be made respondents, because the tribunal will not reorder a seniority list behind the backs of the people who move down. Where they are too many to name, a few can be impleaded in a representative capacity with the bench's permission, and notice can be published to the rest. Our page on affected juniors as necessary parties explains how benches deal with this.
Expect the other side to organise too. In promotee and direct recruit disputes, or between degree and diploma holders in engineering cadres, a joint OA by one camp often triggers a joint OA or an intervention application by the other. That is not a reason to hold back, but it does mean the group's pleading must answer the other camp's best argument, not just the department's.
Colleagues who did not join: will the order help them?
Often, but not always. The Supreme Court summed up the law in State of U.P. v. Arvind Kumar Srivastava (2015). The normal rule is that similarly placed persons should get the same benefit without each having to litigate. The exception is for those who sat on the fence and let years pass, who may be refused on grounds of delay and acquiescence. Where the judgment was meant to benefit everyone in the class, it can be extended to non-parties even so.
In practice, a department that loses a group OA usually implements it for the named applicants first and waits to see who else asks. A colleague who did not join should send a representation soon after the order, attach it, and ask for the same benefit. If that is refused, his or her own OA relying on the earlier order is usually short, but the delay question will be asked. Joining at the start avoids that argument altogether. If a fresh OA on the same point is filed while the group's case is pending, ask for the two to be heard together.
A made-up example: nineteen auditors in Prayagraj
Here's a made-up example. Nineteen senior auditors in a defence accounts office in Prayagraj receive identical letters in mid-2025 saying their second MACP was granted from the wrong date and the excess will be recovered in instalments. They send a joint representation through their section head, and in October 2025 a single letter rejects it for all nineteen.
On screening, two of them turn out to have come on deputation from another accounts organisation, so their service for MACP is counted differently. One retired in early 2026 and now lives in Varanasi, which is within the same bench's territory, so Rule 6(2) allows him to stay in the group. The remaining sixteen are serving in Prayagraj.
Seventeen file one OA at the Allahabad Bench with an application under Rule 4(5), well within a year of the October letter. The two deputationists are advised to file separately, with their own counting set out. The bench allows the joint filing, issues notice and stays the recovery pending the next date. The case on whether the date was wrong is still to be argued; nothing about the stay tells them how the final hearing will go.
Mistakes that slow group cases down
- Adding names to look bigger. A colleague included only to swell the numbers, without papers or a representation, gives the department an easy objection and draws attention away from the strong applicants.
- Listing someone who has not signed. A name in the cause title without that person's signed vakalatnama or consent can lead to the registry returning the file or the person later disowning the case.
- Carrying a different history inside a common case. An undertaking, a deputation spell or a pending penalty belongs in a separate OA unless it truly makes no difference.
- Waiting for talks to finish. Meetings between the association and the department do not stop the one-year clock.
- A relief clause nobody can execute. If the order does not say clearly who gets what from which date, compliance turns into a second round of litigation.
- Forgetting the people who lose if you win. A seniority or promotion OA without the affected staff as respondents is usually sent back for amendment.
- Two groups, two benches, one point. Parallel OAs at different benches on the same circular invite conflicting orders. Coordinate early or ask for a transfer under Section 25.
How the picture changes for different kinds of staff
Group C and Group B staff file most joint OAs, because their pay, MACP and allowance disputes tend to be cadre-wide. Group A officers file together less often, though batch seniority and promotion quota disputes in organised services do produce joint cases. Railway staff frequently go through their federations and unions, and postal staff, including Gramin Dak Sevaks, often bring cadre-wide TRCA or engagement issues as groups. Civilian employees in defence establishments such as MES units and depots come to the CAT, not the Armed Forces Tribunal, and can file jointly in the same way.
Pensioners' groups are common in recovery and pension revision cases, and the residence rule in Rule 6(2) makes it easier for them to file together at one bench. Candidates can file jointly too, and in recruitment there is extra urgency because the panel may be used up while they deliberate. Remember that recruitment disputes for SSC GD Constable and CAPF posts, and service disputes of CAPF, PSU and bank staff, generally go to the High Court rather than the tribunal.
Whatever the group, the drafting is built the same way: one shared question, a chart, a clear relief, and screening of each name. For the basics of any OA, see our page on preparing and filing an OA under Section 19, and if the group needs an urgent stay of recovery or reversion, see interim relief under Section 24.
What to do this week
Get two people to take charge and make a list of everyone affected, with the date each of them received the order and the date of any representation. Mark anyone close to or past the one-year limit. Ask each person for a copy of the order, the representation receipt and a pay slip or PPO, and note anyone with an undertaking, deputation spell or pending inquiry.
If no representation has gone yet, send one jointly signed through proper channel now, and keep its receipt. If the department has already rejected it, do not wait for the next meeting with the administration. For advice on whether your group can file one OA, or for updates on rulings affecting your cadre, contact Advocate B.K. Singh.
Frequently asked questions
Can 50 employees file one case in CAT?
Yes, if the tribunal grants permission under Rule 4(5) of the CAT (Procedure) Rules. The numbers do not decide it; what matters is whether all fifty challenge the same order or rule and want the same relief. The bench can allow some and ask others to file separately.
Is the CAT fee charged per applicant in a joint OA?
No. The first proviso to Rule 7 says that when a single application by several persons or by an association is permitted, the fee is the single fee. Check the current amount and the mode of payment with the registry before filing.
Can our union file the OA without any member joining?
Not under Rule 4(5)(b). At least one affected person must join the association as a co-applicant, and the OA must state the class or grade being represented. Keep the registration papers and the resolution authorising the case ready.
One of us is late by two years. Can he still join the group?
He can be named, but he needs his own application for condonation of delay under Section 21(3), with an affidavit giving his reasons. The bench may admit the OA for the others and refuse him if his explanation is weak.
We are posted in different states. Where do we file together?
Each applicant must be within the bench's territory by posting, or the cause of action must have arisen there at least in part. If the order came from a ministry in New Delhi, the Principal Bench is often the common choice. Retired members may file where they ordinarily live.
Will the order help colleagues who did not join our OA?
Often, but the department may limit it to the named applicants. A colleague who did not join should promptly ask for the same benefit by representation and, if refused, file an OA. Long delay can be held against those who waited.
Can someone withdraw from a joint OA midway?
Yes. An application is filed to delete that person's name, and the case continues for the rest. It is better to agree in writing at the start how withdrawals and costs will be handled.
What happens if an applicant dies while the joint OA is pending?
For claims such as arrears or pension, the legal heirs can apply to be brought on record in place of the deceased applicant. Do this promptly so that the final order covers the family's share.
