How To Request Disclosure From An Employer In Tribunal Proceedings

What disclosure means in Employment Tribunal cases

Disclosure in Employment Tribunal proceedings is the formal process by which each party must share relevant documents with the other side. In employment disputes, particularly wrongful dismissal and unfair dismissal claims, disclosure is often critical because key evidence is usually held by the employer.

Disclosure ensures that both parties have access to documents that are relevant to the issues in dispute, allowing the tribunal to decide the case fairly. The process is governed by the Employment Tribunal Rules of Procedure 2013 and case management directions issued by the tribunal.

Requests for disclosure are commonly made when one party believes the other is withholding documents that are necessary to prove or defend the claim.

Legal framework governing disclosure in tribunals

Employment Tribunal Rules of Procedure 2013

Under the Tribunal Rules, the Employment Tribunal has wide discretion to order disclosure of documents that are:

• Relevant to the issues in the case
• Necessary for a fair hearing
• Proportionate in scope

The tribunal can order standard disclosure or specific disclosure of particular documents.

Overriding objective

Tribunals apply the overriding objective, which requires cases to be dealt with:

• Fairly
• Justly
• Efficiently
• Proportionately

Disclosure orders must align with these principles, balancing relevance against burden.

What counts as “disclosure” in tribunal proceedings

Disclosure refers to documents that are or have been in a party's control, including:

• Emails and internal communications
• HR records and disciplinary notes
• Investigation reports
• Meeting minutes
• Policies and procedures
• Performance reviews
• CCTV or digital records (where relevant)
• Payroll and contractual documents

It does not usually include privileged legal advice between a party and their legal representative.

When to request disclosure from an employer

Requests for disclosure typically arise after:

• Submission of ET1 and ET3 claims
• Preliminary case management hearing
• Exchange of initial disclosure lists

A party may request additional disclosure when:

• Key documents are missing from the employer's list
• There is evidence suggesting relevant documents exist but have not been provided
• The employer's disclosure is incomplete or inconsistent

Step-by-step process for requesting disclosure

Step 1: Identify missing or incomplete documents

Before making a request, it is necessary to identify:

• What documents are missing
• Why they are relevant to the case
• How they support or undermine specific allegations

Examples include:

• Disciplinary investigation notes not disclosed
• Emails referenced in witness statements but not produced
• Comparator performance data in discrimination-related dismissal claims

Step 2: Review the issues list or case management order

Tribunals often set out an “issues list” that defines what must be decided. Disclosure requests should align with these issues.

Relevance is assessed against:

• Claims raised in ET1
• Employer's defence in ET3
• Agreed list of issues (if prepared)

Irrelevant or overly broad requests are unlikely to succeed.

Step 3: Make a formal request to the employer

The first step is usually an informal or formal written request to the employer or their representative.

A clear request should:

• Identify specific documents or categories
• Explain relevance to the case issues
• Reference tribunal directions or rules
• Request confirmation of whether documents exist

This step demonstrates reasonableness before escalating to the tribunal.

Step 4: Apply for specific disclosure from the tribunal

If the employer refuses or fails to disclose relevant material, an application can be made to the Employment Tribunal for a disclosure order.

This is typically done using an application notice and should include:

• Description of documents sought
• Explanation of relevance
• Evidence that disclosure has been requested informally
• Reasons why the documents are necessary for a fair hearing

The tribunal will decide whether to grant the order.

Step 5: Attend a case management hearing (if required)

Tribunals often deal with disclosure disputes during case management hearings. The tribunal may:

• Order standard disclosure
• Require specific categories of documents to be produced
• Set deadlines for compliance
• Refuse overly broad or irrelevant requests

Directions issued at this stage are binding.

Step 6: Enforce disclosure orders if necessary

If an employer fails to comply with a disclosure order, the tribunal may:

• Draw adverse inferences
• Exclude evidence
• Limit the employer's ability to rely on undisclosed documents
• In extreme cases, strike out parts of the defence

Non-compliance can significantly affect case outcomes.

Types of disclosure requests commonly made against employers

1. Disciplinary and dismissal documents

• Investigation reports
• Notes of disciplinary hearings
• Dismissal decision records
• Appeal outcome documents

2. HR and internal communications

• Emails between managers and HR
• Internal decision-making correspondence
• Notes of meetings discussing dismissal

3. Comparator and performance data

Often relevant in discrimination-related dismissal claims:

• Performance reviews of other employees
• Disciplinary outcomes in similar cases
• Promotion and appraisal records

4. Policies and procedures

• Disciplinary policy
• Grievance procedure
• Sickness or performance management policies

Legal tests applied by tribunals for disclosure

Tribunals assess disclosure requests based on:

Relevance

Whether documents are likely to support or undermine a case issue.

Necessity

Whether disclosure is required for a fair determination.

Proportionality

Whether the burden of disclosure is reasonable compared to the value of the documents.

Common challenges in obtaining disclosure

1. Overly broad requests

Requests must be specific. General requests for “all emails” are usually refused.

2. Employer claims of irrelevance

Employers often argue that documents are not relevant. The tribunal decides this issue.

3. Data protection concerns

GDPR considerations may arise, but they do not override tribunal disclosure obligations where documents are relevant.

4. Missing or deleted documents

Tribunals may consider whether documents were intentionally or negligently destroyed.

Strategic importance of disclosure in tribunal claims

Disclosure is often decisive in employment disputes because it can:

• Reveal inconsistencies in employer explanations
• Confirm procedural failures in dismissal
• Demonstrate discriminatory treatment
• Support breach of contract arguments
• Undermine witness credibility

In many cases, the strength of a claim depends on the quality of disclosed documents rather than oral evidence alone.

Time limits and procedural context

Disclosure requests occur within the tribunal timetable, typically:

• After initial case management orders
• Before exchange of witness statements
• Prior to final hearing preparation

Failure to manage disclosure early can limit case preparation time.

Practical considerations when requesting disclosure

• Requests should be targeted and specific
• Relevance must be clearly linked to legal issues
• Written requests should be retained as evidence of cooperation
• Tribunal directions must be followed strictly
• Applications should avoid unnecessary volume or complexity

Key Takeaways

Requesting disclosure from an employer in Employment Tribunal proceedings involves identifying missing relevant documents, making targeted written requests, and if necessary applying to the tribunal for a disclosure order. Tribunals require disclosure to be relevant, necessary, and proportionate, and they rely heavily on disclosed documents when determining wrongful dismissal and related employment claims.

Effective disclosure requests are specific, issue-focused, and aligned with tribunal directions. Where employers fail to comply, tribunals have powers to compel disclosure and draw adverse inferences, which can significantly affect case outcomes.
