"Colour race, nationality or ethnic or national origin"
"17 The statutory amendments clearly require the Employment Tribunal to go through a two-stage process if the complaint of the complainant is to be upheld. The first stage requires the complainant to prove facts from which the Employment Tribunal could, apart from the section, conclude in the absence of an adequate explanation that the respondent has committed, or is to be treated as having committed, the unlawful act of discrimination against the complainant. The second stage, which only comes into effect if the complainant has proved those facts, requires the respondent to prove that he did not commit or is not to be treated as having committed the unlawful act, if the complaint is not to be upheld." 34 We also heard argument on the need for there to be a comparator in the ingredient of less favourable treatment which the complainant must prove for there to be sexual or racial discrimination. However there was no real dispute before us on this point. That a comparison must be made is explicit in the language of the definition of discrimination. In s.1(1)(a) of the SDA one finds 'he treats that other less favourably than he treats or would treat a man'. In s.1(1)(a) of the RRA one finds 'he treats that other less favourable than he treats or would treat other persons'. The comparison must be such that the relevant circumstances of the complainant must be the same as or not materially different from those of the comparator. It is trite law that the complainant need not point to an actual comparator. A hypothetical one with the relevant attributes may do. Our attention was drawn to what was said by Elias J, giving the judgment of the EAT in The Law Society v BahI(2003) IRLR 640 at paragraphs 162 and 163. There it was held that it is not obligatory for ETs formally to construct a hypothetical comparator, though it was pointed out that it might be prudent to do so and that the Employment Tribunal might more readily avoid errors in its reasoning if it did so. Similarly, when Bahl went to appeal, this court ([2004] IRLR 799 at paragraph 156) said that it was not an error of law for an Employment Tribunal to fail to identify a hypothetical comparator where no actual comparator can be found. However, this court also said that not to identify the characteristics of the comparator might cause the Employment Tribunal not to focus correctly on what Lord Nicholls in Shamoon v Chief Constable of the RUC (2003] IRLR 285 at paragraph 7 called 'the less favourable treatment issue' (viz whether the complainant received less favourable treatment than the appropriate comparator) and 'the reason why issue' (viz whether the less favourable treatment was on the relevant proscribed ground). The importance of a failure to identify a comparator or the characteristics of the comparator may vary from case to case, and may be thought to be a particular relevance to the appeal in Emokpae v Chamberlin Solicitors."
