When Does a Tribunal Assume Discrimination Might Have Happened?

If you bring a discrimination claim in the Employment Tribunal, one of the hardest questions is this: When does the tribunal start expecting the employer to explain itself?

That issue was examined in Dr B Jones v ViiV Healthcare UK Ltd Others [2026] EAT 24.

The case involved allegations of race and sex discrimination following a breakdown in the employment relationship. The tribunal accepted parts of the claim.

The Employment Appeal Tribunal rejected that argument.

But the judgment gives helpful guidance on how tribunals should think about discrimination evidence.

Understanding the “Burden of Proof”

In discrimination cases, the law works slightly differently from many other claims.

If the claimant proves facts that suggest discrimination might have happened, the burden can shift. The employer must then show that discrimination was not the reason.

But the tribunal must first decide whether the evidence genuinely supports that inference.

The EAT emphasised that this is not a mechanical checklist.

“A particular factual feature may be found to cause, or contribute to, the shifting of the burden… but it does not give rise to a rule of law.”

What this means

Just because something unusual happened does not automatically prove discrimination.

The tribunal must look at the whole situation, not just one suspicious fact.

The Danger of Over-Simplifying Discrimination Evidence

Sometimes people assume that if an employer behaves unfairly, discrimination must be involved.

The EAT reminded tribunals that this is not necessarily correct.

Earlier cases say that:

“Something more is needed before the burden of proof shifts.”

In plain English: Unfair behaviour alone does not prove discrimination. There must be something connecting that behaviour to the protected characteristic, such as race, sex, disability, or age

Why Context Matters

The EAT stressed that discrimination claims depend heavily on context.

“All depends on the overall factual picture and context of the given case.”

In plain English, the tribunal asks:

• What actually happened?
• What explanations exist?
• Does the situation logically suggest discrimination?

5 Practical Takeaways for Claimants

• Focus on the bigger picture: One suspicious event is rarely enough. Show how several facts point in the same direction.
• Link events to the protected characteristic: Explain why the treatment relates to race, sex, disability, or another protected characteristic.
• Expect the tribunal to examine context carefully: Tribunals rarely draw conclusions from isolated incidents.
• Evidence matters more than suspicion: The tribunal will want concrete facts.
• The tribunal looks at the story your evidence tells.
