"s.(1) A person discriminates against a woman in any circumstances relevant for the purposes of any provision of this Act if - (a) on the ground of her sex he treats her less favourably than he treats or would treat a man. … s.5(3).. A comparison of the cases of persons of different sex … under section 1(1) … must be such that the relevant circumstances in the one case are the same, or not materially different, in the other. s.6(2) 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) in the way he affords her access to opportunities for promotion, transfer or training, or any other benefits, facilities or services, or by refusing or deliberately omitting to afford her access to them, or (b) by dismissing her, or subjecting her to any other detriment."
"(1) Identify the treatment afforded to the Applicant (2) Either: (i) Identify an actual comparator whose circumstances are the same or not materially different to those of the Applicant or (ii) Consider a notional comparator – ie how a man would have been treated in circumstances that are the same or not materially different (3) Consider whether the Applicant has been treated less favourably than the comparator (4) If so, consider whether the Applicant's less favourable treatment was on the ground of her sex."
"(1) A person discriminates against a woman in any circumstances relevant for the purposes of any provision of this Act if – (b) he applies to her a requirement or condition which applies or would apply equally to a man but - (i) which is such that the proportion of women who can comply with it is considerably smaller than the proportion of men who can comply with it, and (ii) which he cannot show to be justifiable irrespective of the sex of the person to whom it is applied, and (iii) which is to her detriment because she cannot comply with it."
"(1) Was a condition or requirement applied to the Applicant? (2) What is the pool for comparison? This is a question of fact for the tribunal which may only be challenged on grounds of perversity: Kidd v DRG (UK) Ltd[1985] ICR 405 . (3) Is the proportion of women that can comply with the condition or requirement considerably smaller than the proportion of men who can comply? This too is a question of fact for the tribunal [subject to the perversity test]: see London Underground Ltd v Edwards (No 2)[1998] IRLR 364 ; R v Secretary of State for Employment ex parte Seymour-Smith[1999] IRLR 253 . (4) Is the condition or requirement to the Applicant's detriment because she cannot comply? (5) Is the condition or requirement justified?"
"(1) A person discriminates against a married person of either sex in any circumstances relevant for the purposes of any provision of Part II [including, in particular, s.6(2)] if - (b) he applies to that person a requirement or condition which he applies or would apply equally to an unmarried person but - (i) which is such that the proportion of married persons who can comply with it is considerably smaller than the proportion of unmarried persons of the same sex who can comply with it, and (ii) which he cannot show to be justifiable irrespective of the marital status of the person to whom it is applied, and (iii) which is to that person's detriment because he cannot comply with it."
"Was the applicant treated less favourably on the grounds of her sex? We find that she was for the following reasons: (a) The respondent's decision to cancel the job-share arrangement directly affected the applicant and Mrs Totney. The refusal to continue with the shift-share arrangement was not due to commercial consideration. It directly impacted on the applicant because she was not able to work those shifts being a primary carer of a young daughter. This was a matter which related to her sex. She had clearly suffered a detriment by being dismissed. This therefore, constitutes direct sex discrimination. (b) We are satisfied that the applicant was treated less favourably than a man. The respondent was much more willing to change hours and arrangements for Mr Highfield than Mrs Highfield. This constituted direct sex discrimination."
"Whilst we are satisfied that the respondent imposed a requirement or condition that employees during the week must work full-time, we are not however satisfied that this requirement was such that the proportion of women who could comply with it was considerable (sic) smaller than the proportion of men who could comply. On the statistical information and submissions made by the applicant 95.5% of female employees could comply with the requirement, whereas 100% of the male employees could comply. That difference does not seem to us to be such that it can be called 'disproportionate'. Accordingly, the claim for indirect sex discrimination fails and is dismissed."
"Whilst we would not condone a tribunal decision which does not set out the relevant legal position and does not make findings of fact on all the principal submissions made, this does not amount to an automatic ground of appeal. It has to be shown that omitting to set out the legal principles or key submissions made has led to a consequent error of law or incorrect finding of fact."
