Burden of proof in discrimination claims (S 136 Equality Act 2010)
- This section applies to any proceedings relating to a contravention of this Act.
- If there are facts from which the court could decide, in the absence of any other explanation, that a person (A) contravened the provision concerned, the court must hold that the contravention occurred.
- But subsection (2) does not apply if A shows that A did not contravene the provision…
- A reference to the court includes a reference to…an employment tribunal
There is some very useful guidance set out on the burden of proof in discrimination claims by the Court of Appeal in Igen v Wong  ICR 931:
“(1) Pursuant to section 63A of the 1975 Act, it is for the claimant who complains of [sex] discrimination to prove on the balance of probabilities facts from which the tribunal could conclude, in the absence of an adequate explanation, that the employer has committed an act of discrimination against the claimant which is unlawful by virtue of Part 2, or which, by virtue of section 41 or section 42 of the 1975 Act, is to be treated as having been committed against the claimant. These are referred to below as “such facts”.
(2) If the claimant does not prove such facts he or she will fail
(3) It is important to bear in mind in deciding whether the claimant has proved such facts that it is unusual to find direct evidence of [sex] discrimination. Few employers would be prepared to admit such discrimination, even to themselves. In some cases, the discrimination will not be an intention but merely based on the assumption that “he or she would not have fitted in”.
(4) In deciding whether the claimant has proved such facts, it is important to remember that the outcome at this stage of the analysis by the tribunal will therefore usually depend on what inferences it is proper to draw from the primary facts found by the Tribunal
(5) It is important to note the word “could” in section 63A(2). At this stage, the tribunal does not have to reach a definitive determination that such facts would lead it to the conclusion that there was an act of unlawful discrimination. At this stage, the tribunal is looking at the primary facts before it to see what inferences of secondary fact could be drawn from.
(6) In considering what inferences or conclusions can be drawn from the primary facts, the tribunal must assume that there is no adequate explanation for those facts.
(7) These inferences can include, in appropriate cases, any inferences that it is just and equitable to draw in accordance with section 74(2)(b) of the 1975 Act from an evasive or equivocal reply to a questionnaire or any other questions that fall within section 74(2) of the 1975.
(8) Likewise, the tribunal must decide whether any provision of any relevant code of practice is relevant and, if so, take it into account in determining such facts pursuant to section 56A(10) of the 1975 Act. This means that inferences may also be drawn from any failure to comply with any relevant code of practice.
(9) Where the claimant has proved facts from which conclusions could be drawn that the employer has treated the claimant less favourably on the ground of [sex], then the burden of proof moves to the employer.
(10) It is then for the employer to prove that he did not commit, or as the case may be, is not to be treated as having committed, that act.
(11) To discharge that burden it is necessary for the employer to prove, on the balance of probabilities, that the treatment was in no sense whatsoever on the grounds of [sex], since “no discrimination whatsoever” is compatible with the Burden of Proof Directive.
(12) That requires a tribunal to assess not merely whether the employer has proved an explanation for the facts from which such inferences can be drawn, but further that it is adequate to discharge the burden of proof on the balance of probabilities that sex was not a ground for the treatment in question.
(13) Since the facts necessary to prove an explanation would normally be in the possession of the respondent, a tribunal would normally expect cogent evidence to discharge that burden of proof. In particular, the tribunal will need to examine carefully explanations for failure to deal with the questionnaire procedure and/or code of practice.”

However, in Efobi v Royal Mail Group Ltd 2017, the EAT has held that S.136 of the Equality Act 2010 – which deals with the burden of proof in discrimination cases – does not impose any initial burden on claimants to establish a ‘prima facie’ case of discrimination. Rather, it requires the tribunal to consider all the evidence, from all sources, at the end of the hearing, so as to decide whether or not there are facts from which it can infer discrimination. If there are such facts, and no explanation from A, the tribunal must uphold the complaint. It may therefore be misleading to refer to a ‘shifting’ of the burden of proof, as this implies, contrary to the language of S.136, that Parliament has required a claimant to prove something.
However orthodoxy was returned in In Ayodele v Citylink Ltd and anor, the Court of Appeal has held that the burden of showing a prima facie case of discrimination under S.136 of the Equality Act 2010 remains on the claimant. This provision made no substantive change to the law when it came into force in October 2010 and Mrs Justice Elisabeth Laing was wrong to hold otherwise in the EAT in Efobi v Royal Mail Group Ltd.
A black man originally from Nigeria brought a number of claims against his former employer C Ltd following the termination of his employment, including claims of race discrimination. The tribunal dismissed his discrimination claims on the basis that A had not established prima facie evidence of less favourable treatment and therefore the burden of proof had not shifted to the respondent. A’s appeal to the EAT was dismissed. Before the Court of Appeal, A raised a new ground of appeal. He submitted that there was a fundamental error in the approach taken by the employment tribunal as to the proper application of the burden of proof under S.136 EqA. He relied on Elisabeth Laing J’s decision in the EAT in Efobi v Royal Mail Group Ltd (Brief 1078) to the effect that the wording of S.136 EqA does not impose a burden of proof on a claimant at all. Instead, it requires the tribunal to consider all the evidence, from all sources, at the end of the hearing, so as to decide whether or not there are ‘facts’ from which it can conclude that discrimination occurred and, if so, it must so find unless the respondent can discharge the burden on it. A pointed to the fact that in his case the tribunal had directed itself that there was a burden of proof on him at the first stage of the enquiry and therefore it fell into error.
The Court of Appeal dismissed the appeal. It noted that the wording of S.136 EqA is different from the wording of the equivalent predecessor provisions, in that there is no longer any express reference to the claimant being required to prove facts. It rejected A’s suggestion that there was an analogy to be drawn with the assessment of the fairness of dismissal in an unfair dismissal case, where there is no burden on either party. In that context, the tribunal is required to make an assessment in which it is not apt to refer to the burden being on either party. However, in a discrimination case, before a tribunal can start making an assessment, the claimant has got to start the case, otherwise, there is nothing for the respondent to address and nothing for the tribunal to assess. The Court of Appeal could see no reason why a respondent should have to discharge the burden of proof unless and until the claimant has shown a prima facie case of discrimination that needs to be answered. Accordingly, it held that there is nothing unfair about requiring a claimant to bear the burden of proof at the first stage.
The Court also observed there was no reason to suppose that Parliament enacted S.136 to remove the burden of proof from a claimant. Furthermore, the EU Burden of Proof Directive (No.97/80), which S.136 gives effect in domestic law, does not require there to be any burden on a claimant at the first stage, and the legal community has proceeded for the last seven years on the assumption that no change of substance was made by S.136. The change in wording from the predecessor provisions simply made clear that what should be considered at the first stage is all the evidence, and not only the evidence adduced by the claimant: it should be regarded as no more than legislative ‘tidying up’. The Court concluded that previous decisions of the Court of Appeal, such as Igen Ltd and ors v Wong and other cases (Brief 777), as approved by the Supreme Court in Hewage v Grampian Health Board (Brief 958), remain good law and should continue to be followed by the courts and tribunals. It, therefore, held that the interpretation of S.136 by Elisabeth Laing J in the EAT in Efobi was wrong and should not be followed.
