Tribunal Evidence Rules for Termination Claims

When an employee brings a termination claim to an Employment Tribunal - for example, for unfair dismissal, discrimination, or breach of contract - the tribunal must decide the case based on evidence submitted by both sides. Understanding the rules governing evidence helps claimants and respondents prepare effectively, meet deadlines, and present information that tribunals can rely on. This article outlines the principal evidence rules in termination claims in England and Wales, including how documents, witness statements and expert evidence are handled, the disclosure process, tribunal powers on evidence, and practical steps to comply with procedural requirements.

1. Governing Evidence Rules and Framework

Employment Tribunal proceedings are governed by the Employment Tribunal Procedure Rules 2024, which set out how evidence is presented and used in hearings. These rules apply to all tribunals in England and Wales and ensure fairness, transparency and procedural order in managing evidence and witnesses.

The key objectives of the evidence regime are to ensure that:

• Relevant facts are properly evidenced by documentation and witness testimony;
• Parties know and can respond to the evidence relied on by the opposing side; and
• The tribunal has the information needed to reach a reasoned judgment.

2. Documents and Disclosure

Duty of Disclosure

Both claimant and respondent must disclose documents relevant to the issues in dispute. Disclosure means giving the other side access to all relevant material in your possession or control, not just documents that support your case. This includes documents that may harm your position but are relevant to key issues.

This duty typically arises after the claim and response are filed and may be formalised through a case management order or directions that specify:

• What documents must be disclosed;
• Deadlines for disclosure; and
• Format for inclusion in the hearing bundle.

Preparing a Hearing Bundle

Once disclosed, documents are collated into a hearing bundle - the set of materials the tribunal and parties will use at the hearing. A hearing bundle includes:

• Employment contracts, payslips and personnel records;
• Correspondence (emails and letters) relevant to dismissal or complaints;
• Grievance/disciplinary records;
• Policies and procedures referred to in the case; and
• Other evidence supporting or challenging the claim.

Tribunals and parties generally exchange copies of the hearing bundle well before the hearing so that all sides can prepare their arguments.

Privileged Documents

Certain documents may be privileged, meaning they are not disclosable. This typically includes legal advice between a party and its solicitor, where privilege applies. Disclosure obligations do not require creation of new evidence; only existing documents are disclosable.

3. Witness Statements

Purpose and Format

Witness statements are the main way witnesses present their factual evidence to a tribunal. They are written accounts of what the witness saw, heard or experienced in relation to issues in the case. Both claimants and respondents usually provide statements from key individuals, including the claimant, managers, colleagues or any person with firsthand knowledge.

Key features of witness statements include:

• Typed paragraphs with numbered sections;
• Chronological, factual recount of events; and
• References to documents in the hearing bundle.

At the end of a witness statement, the witness must sign a statement of truth confirming that the content is true to the best of their knowledge.

Evidence in Chief

Under the 2024 rules, a witness's written witness statement must generally stand as their evidence in chief (primary evidence) unless the tribunal decides otherwise. This means the statement forms the core of their evidence at the hearing, and in most cases it will not be read out loud; instead, it is taken as submitted and witnesses answer questions based on it when called to give oral evidence.

Inspection at Hearing

Witness statements that stand as evidence in chief must be made available for inspection by those attending the hearing, subject to privacy and restrictions on disclosure.

Oral Evidence and Oath

When a witness is called to give oral evidence, they must do so under oath or affirmation. This formalises the evidence and ensures reliability; giving false evidence after swearing an oath may lead to charges of perjury.

4. Expert Evidence

Certain complex issues in termination claims may require expert evidence (for example, on economic loss or medical matters). The Procedure Rules regulate expert evidence to ensure it assists the tribunal and is disclosed properly:

• Parties may only put expert evidence into the proceedings with the tribunal's permission.
• Expert reports must be disclosed to all parties and the tribunal at least 28 days before the final hearing.
• Where independent expert evidence is ordered, only one joint expert may be used for an issue, unless the tribunal directs otherwise.
• An expert's overriding duty is to assist the tribunal, not to advocate for the instructing party.

The tribunal may exclude expert evidence if these rules or a tribunal order is not complied with.

5. Tribunal Powers on Evidence

Case Management and Directions

Tribunals have wide powers to manage evidence and make orders on their own initiative or on application by a party. This includes:

• Ordering disclosure of documents and information;
• Requiring a person to attend to give evidence or produce documents; and
• Setting timetables for the exchange and submission of evidence.

Tribunals may also restrict evidence if it is not relevant, disproportionate, or not disclosed in accordance with their directions.

Written Representations

Tribunals may consider written representations from a party who does not attend the hearing if these are sent to the tribunal and other parties at least seven days before the hearing. This enables tribunals to take into account parties' positions even where they cannot attend in person.

6. Burden and Relevance of Evidence

Relevance

Tribunals only admit evidence that is relevant to issues in dispute. Irrelevant material may be excluded to focus the hearing on matters that directly affect legal claims, such as unfair dismissal, loss of earnings, or discrimination.

Burden of Proof

In many termination claims, the burden of proof initially rests with the claimant to establish facts supporting their claim. Once prima facie evidence is presented, the burden may shift to the respondent to disprove aspects of the claim (for example, lawful reasons for dismissal). Tribunal panels make findings based on the balance of probabilities, meaning the tribunal must be satisfied that a fact is more likely than not.

7. Practical Steps for Handling Evidence

Prepare in Advance

Parties should:

• Identify all documents relevant to the claim;
• Prepare clear, accurate witness statements; and
• Ensure witness statements refer directly to documents in the bundle.

Comply with Disclosure Orders

Respond promptly to disclosure directions and raise issues with the tribunal if relevant documents are withheld. Parties may apply for orders compelling disclosure or adjust deadlines for evidence exchange.

Organise the Hearing Bundle

Provide the other party and tribunal with the final hearing bundle in good time, typically several days before the hearing. This helps both sides prepare and prevents surprises at the hearing.

Key Takeaways

Employment Tribunal evidence rules in England and Wales are designed to ensure fair and orderly presentation of facts and supporting materials in termination claims. Documents must be disclosed and included in a hearing bundle, witness statements form the core of factual evidence, expert reports require tribunal permission and advance disclosure, and written representations can supplement oral testimony. Tribunals have broad powers to manage evidence and require necessary disclosures, while parties must comply with procedural directions and timelines. Clear understanding and careful preparation of evidence are key to presenting a compelling case in unfair dismissal, discrimination, breach of contract and related claims.
