'37. It is probably uncommon to find a real person who qualifies under section 3(4) as a statutory comparator. Lord Rodger's example at para 139 of Shamoon of the two employees with similar disciplinary records who are found drinking together in working time has a factual simplicity which may be rare in ordinary life. At any rate, the question of whether the differences between the circumstances of the complainant and those of the putative statutory comparator are “materially different” is often likely to be disputed. In most cases, however, it will be unnecessary for the tribunal to resolve this dispute because it should be able, by treating the putative comparator as an evidential comparator, and having due regard to the alleged differences in circumstances and other evidence, to form a view on how the employer would have treated a hypothetical person who was a true statutory comparator. If the tribunal is able to conclude that the respondent would have treated such a person more favourably on racial grounds, it would be well advised to avoid deciding whether any actual person was a statutory comparator.' 63. The question, in direct discrimination cases, as to whether the situations of the claimant, on the one hand, and the proposed comparator, whether actual or evidential, on the other, are comparable is a question of fact and degree: Hewage v Grampian Health Board[2012] UKSC 37 ;[2012] ICR 1034 . The Supreme Court upheld the view of the Inner House of the Court of Session, restoring the decision of the Employment Tribunal, that unless the Employment Tribunal's judgment could be said to be absurd or perverse it was not for the Appeal Tribunal to impose its own judgment on the point. To like effect, in Kalu v Brighton & Sussex University Hospitals NHS Trust (UKEAT/0609/12 ), Langstaff P said, at para 24, that the identification of a comparator is a question of fact. 64. In order for a comparator to be an actual or statutory comparator, is not necessary that the circumstances are the same in every particular. In Vento, above, Lindsay J said, at para 12: '… it is all too easy to become nit-picking and pedantic in the approach to comparators. It is not required that a minutely exact actual comparator has to be found.' 65. In Kalu, at para 24, Langstaff P said, '
