Explore how evidence of discrimination is gathered and assessed in dismissal cases under UK employment law. This comprehensive guide explains documentary and witness evidence, burden of proof, causation, tribunal procedures, practical steps for claimants and employers, and key legal principles in England and Wales.

When an employee believes their dismissal was influenced by discriminatory treatment, proving that discrimination is central to bringing a successful claim at an Employment Tribunal. Discrimination claims connected to dismissal typically arise under the Equality Act 2010, and can involve direct discrimination, indirect discrimination, harassment, or victimisation. This article explains what types of evidence tribunals consider, how evidence is evaluated, legal principles such as burden of proof, and practical steps employees and employers should take when preparing or responding to a discrimination dismissal claim in England and Wales.
Understanding Discrimination in Dismissal Cases
The Equality Act 2010 protects employees from unfavourable treatment because of protected characteristics, including age, disability, gender reassignment, marriage and civil partnership, pregnancy and maternity, race, religion or belief, sex, and sexual orientation. Dismissal linked to a protected characteristic may give rise to a claim for unlawful discrimination. An employee may also claim victimisation where dismissal relates to raising discrimination complaints.
The Burden of Proof in Discrimination Claims
Stage One: Prima Facie Evidence
Initially, the claimant (the employee) must present evidence showing factual circumstances from which the tribunal could conclude, in the absence of any other explanation, that unlawful discrimination occurred. This is often referred to as establishing a prima facie case.
If the claimant provides sufficient facts from which discrimination could be inferred, the burden of proof shifts to the employer to demonstrate that the treatment was for a non‑discriminatory reason.
Balance of Probabilities
Tribunals decide civil claims on the balance of probabilities. This means the tribunal must be satisfied that it is more likely than not that the claimant's version of events is true. Evidence does not need to be conclusive, and in many cases tribunals will make inferences from proved facts when direct evidence is not available.
Types of Evidence in Discrimination Dismissal Cases
1. Documentary Evidence
Documents often form the backbone of a strong discrimination claim. Relevant materials include:
- Employment contracts, policies and handbooks: These can show whether employees in similar circumstances were treated differently.
- Emails and written correspondence: Messages that reference protected characteristics or reveal inconsistency in employer decision‑making.
- Meeting minutes and performance reviews: Records of meetings leading up to dismissal, especially if they show inconsistent application of rules or criteria.
- Internal reports or complaints: Formal grievances alleging discriminatory conduct.
2. Chronologies and Notes of Events
Employees are encouraged to record details of discriminatory acts as they occur. Notes should include dates, people involved, specific conduct, and how it impacted the employee. Such chronologies are often persuasive where formal written records are sparse.
3. Witness Statements
Statements from colleagues or other witnesses who observed discriminatory conduct can support a claimant's account. Witness testimony should describe what was seen or heard and how it related to the dismissal.
4. Statistical or Comparative Evidence
For indirect discrimination claims, statistical data showing that a particular group is disproportionately affected by an employer's practices can be relevant. Similarly, comparing how other employees were treated in similar circumstances may show inconsistent treatment.
5. Patterns of Behaviour
Discrimination is often proved through patterns of treatment rather than single incidents. A series of actions that cumulatively suggest bias or discriminatory motivation can be strong evidence, even if each incident in isolation is ambiguous.
Direct vs Indirect Evidence
Direct Evidence
This includes explicit statements or documented actions indicating discriminatory intent. For example, comments made by decision‑makers that reference a protected characteristic can be powerful evidence of direct discrimination.
Example: A tribunal may consider emails or messages showing that dismissal decisions were influenced by an employee's race, disability, or other protected characteristics.
Indirect Evidence and Inferences
Direct evidence is often unavailable. Tribunals may infer discrimination from patterns of behaviour, inconsistent procedures, or deviations from normal practice. This requires careful collation of facts that, when viewed together, point towards discriminatory motivation.
Evidence of Causation and Link to Dismissal
A discrimination claim linked to dismissal must show that the protected characteristic was a reason for the dismissal. Evidence must therefore establish a causal connection between the discriminatory conduct and the dismissal decision. This could include:
- Timing of events: A protected characteristic being raised shortly before adverse action.
- Disparities in treatment: A claimant treated less favourably than colleagues without the same protected characteristic.
- Employer explanations: Inconsistencies in employer's reasons or insufficient justifications for dismissal after facts suggest discrimination.
Practical Steps to Gather and Present Evidence
Keep Detailed Records
Employees should maintain contemporaneous records of discriminatory conduct, internal complaints, and meetings leading up to dismissal. A timeline of events helps present the narrative clearly at tribunal hearings.
Request Documents Through Disclosure
Parties can use the tribunal's disclosure process to obtain relevant documents held by the employer, such as emails, internal reports, and policies that may not otherwise be accessible.
Prepare Witness Statements
Witness statements should be factual and concise, outlining what each witness observed or experienced that is relevant to the discrimination claim. Names, dates, and specific conduct help tribunals assess credibility and relevance.
Engage Early Conciliation
Before bringing most discrimination claims to an Employment Tribunal, claimants must contact Acas for Early Conciliation, which can also help clarify issues and evidence needed before formal proceedings.
Employer Considerations When Responding to Evidence
Employers defending a discrimination dismissal claim should be prepared to:
- Demonstrate legitimate, non‑discriminatory reasons for dismissal with robust documentation.
- Provide evidence that the dismissal decision was consistent with policies and applied fairly across all employees.
- Address any prima facie evidence of discrimination by explaining decision‑making processes and evidencing objective justification where relevant.
Case Law on Burden and Evidence
In Royal Mail Group Ltd v Efobi, the UK Supreme Court confirmed that a claimant must first establish sufficient facts from which discrimination could be inferred. If this is achieved, the burden then shifts to the employer to prove that the treatment was not discriminatory.
In Stefanko v Doherty and Maritime Hotel Ltd, the Employment Appeal Tribunal found that, once evidence suggests discriminatory conduct, employers bear the burden of disproving discrimination.
Key Takeaways
Proving discrimination in dismissal cases in England and Wales requires a careful compilation of evidence to satisfy the tribunal that unlawful bias influenced the dismissal. Claimants must establish initial facts from which discrimination can be inferred, after which the burden of proof can shift to the employer to justify its actions. Key evidence includes documentary records, witness statements, patterns of behaviour, and comparative treatment analysis. Understanding how to gather, organise, and present evidence is crucial for employees pursuing claims and employers defending them.
