"… [A] person discriminates against a woman if … on the ground of her sex, he treats her less favourably than he treats or would treat a man …"
"A comparison of the cases of persons of different sex … under s. 1 (2) … must be such that the relevant circumstances in the one case are the same, or not materially different, in the other."
"It is unlawful for a person, in the case of a woman employed by him at an establishment in Great Britain, to discriminate against her – (a) … (b) by dismissing her, or subjecting her to any other detriment."
"Where, on the hearing of [a] complaint [under the Act], the complainant proves facts from which the tribunal could, apart from this section, conclude in the absence of an adequate explanation that the respondent – (a) has committed an act of discrimination … against the complainant which is unlawful by virtue of Part II … , or (b) … the tribunal shall uphold the complaint unless the respondent proves that he did not commit … that act."
"44 Turning to the complaint of sex discrimination, there were three essential questions for the Tribunal to answer, which are addressed in turn below. Less favourable treatment? 45 The first question for the Tribunal was whether the claimant had been treated less favourably than a real or hypothetical comparator. The Tribunal considered that a hypothetical comparator in this case would be a female, relatively senior, officer of the first respondent who had allegedly committed a violent sexual assault on a male officer of higher status than she, which male officer held a post within the senior management team of the first respondent. The Tribunal was satisfied that this comparison complied with section 5(3) of the 1975 Act that "the relevant circumstances in the one case are the same, or not materially different, in the other"
"In the present case we are satisfied that there were no facts established in this case which would justify any inference that the decision taken by the union to withdraw support for the respondent was taken on a gender related basis rather than on a conduct related basis. The crucial inference drawn by the tribunal was that they were satisfied that a female would have been treated in a non-judgmental way and received the usual representation in a time of difficulty. We have been unable to find any facts established which would justify the drawing of that inference, nor indeed are there any other inferences which can legitimately be drawn from the evidence which would lead to that final inference ."
"… based on an unreasonable and unsubstantiated presumption of guilt, arising from your belief that because my accuser is a woman she must be believed and because I am a man it must automatically be assumed that I am guilty of the offence."
"The second respondent's evidence was that he was very conscious that he had only heard X's account and did not know what the claimant would say but, despite that, he believed that the first respondent was employing a violent rapist in a very senior position with authority over female staff and access to confidential information relating to vulnerable children. In this regard, however, in answer to a question from the claimant, H confirmed that, in his opinion, suspending the claimant would have removed any ongoing threat. The second respondent said that he had not raised these matters with the claimant as, "he was bound to categorically deny the allegations"
" Ground 1 There was no evidence to support the Tribunal's finding that a woman in the same, or not materially different, circumstances would have been treated more favourably than C. The Tribunal was therefore wrong to conclude that (a) there was less favourable treatment afforded to C and (b) even if there was, such treatment was on the grounds of his sex. Ground 4 The Tribunal failed to identify which, if any, "primary facts" it relied upon for the drawing of inferences or how such facts supported their conclusion that, had the hypothetical aggressor been a female, such a person would not have been treated as C was treated. Furthermore the Tribunal failed to explain why it rejected R2's assertion that he would have acted in the same way irrespective of the alleged aggressor's sex and irrespective of the alleged victim's sex."
" Ground 3 The Tribunal erred in law by failing, when conducting the hypothetical comparative exercise, to take account of all the material circumstances, including the fact that R2 acted on legal advice prior to dismissing C. Furthermore the Tribunal erred in law, when making the comparison, by failing to use at its starting point a like for like female comparator who was not only capable of the most serious physical assault on a male but also presented a real risk of carrying out such an assault. … Ground 5 The Tribunal's finding that R2 would not have had the same concern with regard to the potential risk posed by C (if C had been a woman) was not supported by any evidence and, moreover, was a finding based upon stereotypical assumptions on the part of the Tribunal itself, namely that female aggressors are not as potentially dangerous to males as male aggressors are to females. Ground 6 The Tribunal erred in law by failing to consider how R2 might have acted had the alleged aggressor and victim both been female or indeed both male."
