"77 ON THE EVIDENCE and on the basis of inference drawn from primary facts for which no satisfactory explanation was given we find:-
"54 It was submitted that Mr Y discriminated against Miss X in subjecting her to the alleged sex attack."
"55 This is accepted. Mr Y did not deny that he had imposed his unwanted attentions on Miss X or that he had frightened her. The only disparity was as to the extent of his attentions. We make no finding as to the extent, but are satisfied on Mr Y's evidence and his statement to the investigators that he did impose his unwanted sexual attentions on Miss X with sufficient zeal to frighten her. He therefore subjected her to a "detriment". There was no suggestion that he would have imposed similar unwanted attentions on a male. We therefore find that he treated her "less favourably" than he would have treated a man. In view of the requirement in the Prison's Disciplinary Code that officers, "must not" allow their off-duty conduct to bring discredit on the Prison Service, we find that Mr Y's conduct was "in relation to employment". It therefore constituted unlawful discrimination within the meaning of sections 1 and 6 of the 1975 Act and "a contravention of this Act" within the meaning of section 4. We find that he further discriminated against Miss X by way of victimisation under section 4 in that in seeking to "get at" her he treated her "less favourably than he would treat other persons" on the ground that she had "alleged that the discriminator had committed an act ... which would amount to a contravention of this Act.""
"... was treated "less favourably" within the meaning of section 4 of the 1975 Act in that she was subjected to determined and persistent badgering in respect of an old-established lie. The inference to be drawn from that less favourable treatment was that Mr Lockley hoped to discredit Miss X because of her allegations against Mr Y. No other satisfactory or adequate explanation for Mr Lockley's conduct was given and we find that it constituted victimisation within the meaning of section 4."
"The tribunals are free, and are indeed bound, to interpret the ordinary, and readily understandable, words 'in the course of employment' in the sense in which every layman would understand them. This is not to say that when it comes to applying them to the infinite variety of circumstance which is liable to occur in particular instances - within or without the workplace, in or out of uniform, in or out of rest-breaks - all laymen would necessarily agree as to the result. That is what makes their application so well suited to decision by an industrial jury. The application of the phrase will be a question of fact for each industrial tribunal to resolve, in the light of the circumstances presented to it, with a mind unclouded by any parallels sought to be drawn from the law of vicarious liability in tort."
