Employment Tribunal hearing bundles: why the bundle is not the case

The central distinction

A hearing bundle can look like the case. It has the documents. It has the page numbers. It is sent to the Tribunal. Witnesses may be taken through it. Representatives may refer to it throughout the hearing.

That can create a dangerous impression. The bundle is not the case. It is the hearing file.

Its purpose is to help the Tribunal find and use the documents it needs to decide the issues. It should be organised, relevant and usable. It should not become a document dump, a private archive, a witness statement, a chronology, a submissions document or a tactical weapon.

In Employment Tribunal proceedings, that distinction matters. A badly prepared bundle can make a case harder to follow. A bloated bundle can bury the real issues. A narrow bundle can leave out documents that matter. A disputed bundle can create avoidable delay. A late document can change the shape of a hearing. A redacted document can raise questions about fairness, privacy and open justice.

This article concerns Great Britain Employment Tribunal procedure. It does not address Northern Ireland tribunal procedure.

What belongs in the bundle

The first mistake is to treat the bundle as a collection of every document a party thinks is important. That is not the right approach.

A hearing bundle should contain documents needed for the hearing. That usually means documents referred to in witness statements, documents likely to be used in cross-examination, and documents relevant to the issues the Tribunal has to decide. That is narrower than “everything connected to the workplace dispute”.

A claimant may want to include every email, grievance note, screenshot, policy, message, diary entry and background document. A respondent may want to include every HR record, policy version, investigation document and internal note. Each may think more documents make the case stronger. Often, the opposite is true.

Too many documents can obscure the point. A Tribunal hearing is not improved by hundreds of pages that nobody reads, nobody explains and nobody uses. The bundle should help the Tribunal decide the case. It should not make the case harder to decide.

Disclosure, issues and evidence

Disclosure and the hearing bundle are connected, but they are not the same thing. Disclosure is the process by which parties identify and exchange relevant documents. The hearing bundle is the organised file of documents for the hearing.

A document may be disclosed because it is relevant, but still not need to be in the final hearing bundle. It may not be referred to in a witness statement. It may not be needed for cross-examination. It may not assist the Tribunal in deciding the live issues.

Equally, a document should not be left out merely because it is awkward, disputed, embarrassing or inconvenient if it is needed for the hearing.

The bundle should follow the issues. A document is not included just because it exists, because one side wants the Tribunal to see it, or because it mentions the manager, grievance, dismissal, protected disclosure, sickness absence or workplace dispute. It should be included because it is needed for the hearing.

In an unfair dismissal claim, the bundle may need the dismissal letter, investigation documents, disciplinary notes, appeal material, relevant policies and documents going to the reason for dismissal and fairness of the process.

In a discrimination claim, the bundle may need documents showing the alleged treatment, decision-making process, comparator material where relevant, grievance records, occupational health material, reasonable adjustment correspondence and documents that help the Tribunal decide why something happened.

In a whistleblowing claim, the bundle may need the alleged disclosures, records showing who knew what and when, documents about the alleged detriment or dismissal, and communications that may support or undermine the connection being alleged.

Those examples are not fixed categories. The point is simpler: the bundle should be issue-led.

A document in the bundle is not automatically agreed

Another common mistake is to think that if a document is in the bundle, everyone agrees with it. That is wrong.

Agreement to include a document in the bundle is not usually agreement that the document is accurate, complete, fair, reliable or decisive. It is not usually agreement that the document means what the other party says it means. It normally means the document is to be available at the hearing.

A grievance outcome may be in the bundle, but the claimant may dispute its reasoning. A disciplinary note may be in the bundle, but the respondent may dispute the claimant’s interpretation of it. A screenshot may be in the bundle, but a party may challenge its context or completeness. An occupational health report may be in the bundle, but the parties may disagree about what it shows.

The document is one thing. The argument about the document is another. The Tribunal decides what weight to give the evidence. The bundle does not decide that.

The bundle is not witness evidence or submissions

A hearing bundle is not a witness statement. This is a common problem, especially where parties are unrepresented.

A party may assume that putting a document in the bundle is enough. They may think the Tribunal will read it, understand why it matters, connect it to the right issue, and draw the conclusion the party wants. That is unsafe.

Documents need to be used properly. Witness statements explain the evidence. Cross-examination tests it. Submissions argue what follows from it. The bundle is the place where the document can be found. It is not the explanation of the document.

If a claimant says an email shows discrimination, the witness statement should explain the context and why the email matters. If a respondent says a disciplinary note supports the dismissal decision, the relevant witness evidence should explain the process and the decision. If a document contradicts a party’s account, the point may need to be put in cross-examination.

The bundle is also not a written argument. It should not be organised in a way that smuggles advocacy into the document file. It should not contain argumentative labels, selective commentary, misleading section headings, unnecessary duplication or private annotations.

The argument belongs in submissions. The evidence belongs in witness statements and oral evidence. The documents belong in the bundle. Those distinctions should not be blurred.

Disputed documents and bundle control

Sometimes the parties disagree about whether a document should be included. That is normal.

One side may say the document is irrelevant. The other may say it is essential. One side may say it is privileged or protected. The other may say privilege has been waived or does not apply. One side may want redaction. The other may say the redaction removes material needed for a fair hearing.

The wrong answer is to pretend the dispute does not exist. A party preparing the bundle should not silently omit disputed documents and hope the issue goes away. Nor should a party insist that everything it wants must be inserted without explanation.

That approach protects both sides. It avoids ambush. It reduces hearing-day argument. It gives the Tribunal a proper route to decide what should be before it.

Bundle control is not case control

In many Employment Tribunal cases, the respondent prepares the bundle. There may be practical reasons for that: the respondent may have more resources, a representative, HR records, electronic systems or the administrative ability to prepare the file.

But preparing the bundle does not mean owning the case. The bundle should reflect the Tribunal’s order and the documents needed for the hearing. It should not reflect only the respondent’s preferred version of events.

A claimant should not assume that the respondent’s draft bundle is correct. A respondent should not assume that preparing the bundle gives it tactical control over what the Tribunal sees.

Both sides should check the index. Both sides should check pagination. Both sides should check that documents referred to in witness statements are included. Both sides should raise omissions promptly.

A bundle is not a private file prepared for one party. It is the Tribunal’s working file for the hearing.

Size, late documents and electronic files

A large bundle can look impressive. It can also be a problem.

Employment Tribunal cases often produce many documents: emails, messages, policies, minutes, notes, screenshots, letters, grievances, appeal documents, occupational health material, rotas, payslips, medical evidence and internal records. But volume is not the same as relevance.

An overlarge bundle can make it harder for the Tribunal to find the important documents. It can waste hearing time. It can make witness questioning unfocused. It can increase preparation burden. It can distract everyone from the real issues.

The Tribunal’s task is not to read a workplace archive. Its task is to decide the legal claims before it.

That does not mean parties should strip the bundle down so far that important documents are missing. The risk runs both ways. A bundle that is too large can bury the case. A bundle that is too narrow can distort it.

Late documents are not simple

Late documents create some of the hardest practical problems.

A document may be found late. A party may realise late that it matters. A witness statement may refer to a document that is not in the bundle. A respondent may discover an email in an archived system. A claimant may produce a screenshot on the morning of the hearing. A party may say a document has only just become relevant because of the way the other side has put its case.

The Tribunal will usually be concerned with fairness. Is the document relevant? Why is it late? Could it have been found earlier? Has the other side seen it before? Would the other side need time to consider it? Would admitting it require further evidence? Would excluding it prevent a fair hearing? Would the hearing be delayed or adjourned? Is there a pattern of non-compliance?

There is no safe assumption that a late document will automatically be excluded. There is also no safe assumption that it will automatically be admitted. The answer is fact-sensitive.

That is why parties should deal with documents early. Search early. Disclose early. Check the bundle early. Raise omissions early. If something goes wrong, explain it promptly. The worst course is silence until the hearing starts.

Electronic hearing files must be usable

More Tribunal work now involves electronic documents. Where the Tribunal orders an electronic hearing file, usability matters.

A file that cannot be searched, navigated or paginated properly can create avoidable delay. If the page numbers in the PDF do not match the page numbers in the index, the hearing becomes harder. If the file is not searchable, documents are harder to find. If documents are upside down, duplicated, badly scanned or scattered across separate files without a workable index, the problem becomes practical very quickly.

Electronic does not mean informal. An electronic hearing file should be prepared so that the Tribunal, parties, representatives and witnesses can use the same document set. Page numbers should work. The index should work. Important sections should be easy to find. Late additions should be handled consistently and, where necessary, by direction.

This matters for fairness as well as convenience. If a witness cannot find the document, if one party is using different pagination, or if the Tribunal is being taken to the wrong page, the hearing can lose focus. A usable bundle is part of proper preparation.

Sensitive, public and settlement material

Some bundles contain sensitive material. That may include medical records, occupational health material, comparator information, third-party names, confidential HR material, commercial information, client names, settlement material or private messages.

The fact that material is sensitive does not automatically mean it should be excluded. The fact that material is relevant does not automatically mean it should appear without control.

The Tribunal may need to consider redaction, anonymisation, restricted access, separate handling, or a privacy or restriction order. That is particularly important where documents may be referred to at a public hearing or where non-parties may be affected.

Redaction should not be used to remove awkward material. Anonymisation should not be used simply to make the case more comfortable for one party.

If a party wants redaction or anonymisation, it should be able to explain why. Is the material irrelevant? Is it confidential? Is it private? Is it privileged? Does it identify a third party? Is the proposed restriction necessary and proportionate? Does it still allow the other side to understand and test the document?

The same point applies in reverse. A party opposing redaction should explain why the unredacted material matters. Is the identity important? Is the context needed? Does the redaction change the meaning of the document? Is the material necessary for cross-examination or a live issue?

The question is not simply whether the material is uncomfortable. The question is how the Tribunal can deal with the case fairly while respecting open justice, privacy and the rights of those affected.

Public hearings and document access

Final hearings are generally public. That matters for bundles.

Parties sometimes assume that documents in an Employment Tribunal case remain private because they were exchanged between the parties. That assumption may be wrong once documents are used in a public hearing or referred to in evidence.

Open justice does not mean every document is automatically available to everyone in every case. Equally, inclusion in a hearing bundle, or reference to a document in a Tribunal judgment, does not automatically mean that the underlying document has lost confidentiality or can be freely reused outside the proceedings. Both assumptions are unsafe.

A hearing bundle is not permanently private simply because it was exchanged between the parties. But it is also not automatically public property simply because it was used in Tribunal proceedings.

This is another reason to deal with sensitive material before the hearing. If a party believes a document needs redaction, anonymisation, restricted access or special handling, the issue should be raised properly. Waiting until the document is about to be used in open hearing may create avoidable difficulty.

The Tribunal may need to balance competing considerations: fair hearing, open justice, privacy, confidentiality, freedom of expression, the rights of third parties, and the practical conduct of the hearing. That balance is not helped by last-minute surprises.

Without-prejudice, Acas and COT3 material

Some documents need particular care before they are put in a hearing bundle.

Without-prejudice correspondence, Acas communications, protected settlement discussions and COT3-related material should not be treated as ordinary documents.

Sometimes settlement material is not admissible. Sometimes there may be an exception. Sometimes a party may need to rely on such material because the validity, construction or effect of an agreement is itself in dispute.

That is not an area for guesswork. A party should not simply include without-prejudice or Acas material in the bundle because it seems useful. Equally, a party should not assume that such material can never be considered in any circumstances.

The route matters. If settlement or protected material is involved, the issue should usually be raised separately and carefully. It may need legal advice. It may need a Tribunal direction. It may need a clear explanation of why the material is said to be admissible or protected.

Practical checks for both sides

Hearing bundles can be especially difficult for litigants in person. The terminology is unfamiliar. The technical requirements may be unclear. A litigant may not understand the difference between disclosure, bundle inclusion, witness evidence and submissions.

They may think the respondent’s bundle is final. They may think their own documents will be read even if they are not in the bundle. They may not know how to challenge omissions.

The Tribunal may need to assist with understanding the process. But assistance is not the same as taking over the case. A litigant in person still needs to read the Tribunal’s orders, check the bundle, raise missing documents, identify disputed material, and ask for clarification before the hearing if something is unclear.

The same applies to respondents dealing with litigants in person. A respondent should not use bundle preparation to take unfair advantage of confusion. If a claimant has clearly identified documents they say are relevant, and those documents are disputed, the issue should be dealt with openly.

A fair bundle process helps both sides. It reduces surprise. It reduces adjournment risk. It helps the Tribunal focus on the real dispute.

A poor bundle can damage the respondent as much as the claimant. If the Tribunal cannot find the documents, if the pagination is wrong, if relevant material appears late, or if disputed documents have been omitted without explanation, the hearing may become harder, slower and more contentious.

A disciplined bundle helps the respondent too.

The Legal Lens point

The hearing bundle is not the case. It is the file the Tribunal uses to hear the case.

That distinction matters. The case is made up of the pleaded claims and responses, the issues, the evidence, the documents, the witness evidence, the submissions and the Tribunal’s findings. The bundle is only one part of that process.

It is important because it shapes what is easy to find, what witnesses are taken to, what documents are used in cross-examination, and how the Tribunal follows the dispute. But it is not everything.

The bundle should help the Tribunal decide the case. It should not bury the case, distort the case, or replace the case.

For claimants, the lesson is to check the bundle before the hearing and connect documents to the issues. For respondents, the lesson is to prepare the bundle fairly, not tactically. For both sides, the lesson is the same.

The bundle is not the case. It is the working file of documents the Tribunal needs to decide it.
