“33.4. … the claimant has shown that he is of a particular age group and that he has been treated differently to others not within that age group.”
“33.5. … this is not sufficient of itself to support a prima facie conclusion that the decisions were made on the grounds of age; more is required. The claimant must demonstrate the Shamoon [ v Chief Constable of the Royal Ulster Constabulary[2003] IRLR 285 HL] linkage.”
“33.6.5. In our judgement unless there is other evidence, either direct or inferential, from which we can see that the decision not to offer the claimant was because of the claimant’s age (whether that was the only reason or just a partial but operative reason) the statistics will not assist him.”
“34. … making a decision about whether anyone in the comparator group relied upon was treated more or less favourably than the claimant. …”
“(1) A person (A) discriminates against another (B) if, because of a protected characteristic, A treats B less favourably than A treats or would treat others. (2) If the protected characteristic is age, A does not discriminate against B if A can show A’s treatment of B to be a proportionate means of achieving a legitimate aim.”
“(2) 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. (3) But subsection (2) does not apply if A shows that A did not contravene the provision.”
“73. No doubt in most cases it will be sensible for a tribunal formally to analyse a case by reference to the two stages. But it is not obligatory on them formally to go through each step in each case. … 74. Another example where it might be sensible for a tribunal to go straight to the second stage is where the employee is seeking to compare his treatment with a hypothetical employee. In such cases the question whether there is such a comparator - whether there is a prima facie case - is in practice often inextricably linked to the issue of what is the explanation for the treatment, as Lord Nicholls pointed out in Shamoon … paras 7-12, it must surely not be inappropriate for a tribunal in such cases to go straight to the second stage. 75. The focus of the tribunal's analysis must at all times be the question whether or not they can properly and fairly infer race discrimination. If they are satisfied that the reason given by the employer is a genuine one and does not disclose either conscious or unconscious racial discrimination, then that is the end of the matter. It is not improper for a tribunal to say, in effect, “there is a nice question as to whether or not the burden has shifted, but we are satisfied here that, even if it has, the employer has given a fully adequate explanation as to why he behaved as he did and it has nothing to do with race”.”
“56. … The bare facts of a difference in status and a difference in treatment only indicate a possibility of discrimination. They are not, without more, sufficient material from which a tribunal “could conclude” that, on the balance of probabilities, the respondent had committed an unlawful act of discrimination. 57. “Could … conclude” in section 63A(2) must mean that “a reasonable tribunal could properly conclude” from all the evidence before it. This would include evidence adduced by the complainant in support of the allegations of sex discrimination, such as evidence of a difference in status, a difference in treatment and the reason for the differential treatment. It would also include evidence adduced by the respondent contesting the complaint. Subject only to the statutory “absence of an adequate explanation” at this stage …, the tribunal would need to consider all the evidence relevant to the discrimination complaint; for example, evidence as to whether the act complained of occurred at all; evidence as to the actual comparators relied on by the complainant to prove less favourable treatment; evidence as to whether the comparisons being made by the complainant were of like with like as required by section 5(3) of the 1975 Act; and available evidence of the reasons for the differential treatment. 58. The absence of an adequate explanation for differential treatment of the complainant is not, however, relevant to whether there is a prima facie case of discrimination by the respondent. The absence of an adequate explanation only becomes relevant if a prima facie case is proved by the complainant. The consideration of the tribuna l then moves to the second stage. The burden is on the respondent to prove that he has not committed an act of unlawful discrimination. He may prove this by an adequate non-discriminatory explanation of the treatment of the complainant. If he does not, the tribunal must uphold the discrimination claim. … 65. There has been a debate in the cases and on this appeal as to what evidence from the respondent is relevant at the first stage. It was observed in Igen … para 24, that the language of section 63A(2) points to the complainant having to prove facts, but there is no mention of evidence from the respondent. The court added that it would be unreal if the employment tribunal could not take account of evidence from the respondent, if such evidence assisted the employment tribunal to conclude that, in the absence of an adequate explanation, unlawful discrimination by the respondent on a proscribed ground would have been established. The court referred to the examples given in Barton [ v Investec Henderson Crosthwaite Securities Ltd ][2003] ICR 1205 of unsatisfactory conduct of the respondent being relevant to the drawing of inferences at the first stage: for example an unsatisfactory response to the statutory questionnaire or a breach of the code of practice by the respondent.”
