"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, or (b) he applies to her a requirement or condition which he 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
"(1) It is unlawful for a person, in relation to employment by him at an establishment in Great Britain, to discriminate against a woman - (a) in the arrangements he makes for the purpose of determining who should be offered that employment, or (b) in the terms on which he offers that employment, or (c) by refusing or deliberately omitting to offer her that employment"
"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 to 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."
"For completeness and because of deference to the arguments put forward we find that the applicant had in fact suffered a detriment if only because of the loss of a job that she loved so much and that despite some conflicting evidence as to the costs of child care that the applicant would have been justified in coming to the conclusion generally that an appropriate level of child care was beyond her financial resources."
"36. It is for the national court, which has sole jurisdiction to make findings of fact, to determine whether and to what extent the grounds put forward by an employer to explain the adoption of a pay practice which applies independently of a worker's sex but in fact affects more women than men may be regarded as objectively justified economic grounds. If the national court finds that the measures chosen by Bilka correspond to a real need on the part of the undertaking, are appropriate with a view to achieving the objectives pursued and are necessary to that end, the fact that the measures affect a far greater number of women than men is not sufficient to show that they constitute an infringement of article 119.
"In my judgment 'justifiable' requires an objective balance between the discriminatory effect of the condition and the reasonable needs of the party who applies the condition."
"... it is not sufficient for the employer to establish that he considered his reasons adequate."
"It is obviously desirable that the tests of justifiability applied in all these closely related fields should be consistent with each other."
"We turn thereafter to the thrust of the argument surrounding the case. Namely whether or not the rule is objectively justifiable. We find that it is. We have been referred to the case of Hampson v Department of Education and Science[1989] ICR 179 and the dictum of Lord Justice Balcombe, where he said 'justifiable requires an objective balance between the discriminatory effect of the condition and the reasonable needs of the party who applied the condition'. An employer must show that the discrimination is objectively justified, that is that the means chosen for achieving that objective correspond to a real need on the part of the undertaking, are appropriate with a view to achieving the objective in question and are necessary to that end. That is a burden of proof which must be discharged by the employer on the balance of probabilities."
"In addition there would have to be taken into consideration the training costs and the appointment of a further employee to cover the applicant who herself on occasions might be unavailable for work, which would give rise to potential further difficulties in cover of a sufficient quality and standard."
"We conclude that the employer in considering the requests in the light of the needs of the company decided on good grounds that anything other than a full time employee filling the receptionist position would result in disruption of customer continuity which would be detrimental to the company's business. We are satisfied that this is the case because that has been the position pointed out to the applicant when she first returned to work and explained as being based upon what had been the company experience in her absences. We bear in mind that this was a company which was based essentially on telesales where the receptionist provided a vital role in that area and also in the supporting role of clerical assistant. We consequently are of the view that the condition which was discriminatory was nevertheless objectively justifiable."
"A finding of fact which is unsupported by any evidence clearly involves an error of law. The Tribunal cannot have directed itself, as it should, that findings of fact need some evidence to support them. The danger in the approach of May LJ is that an appellate court can very easily persuade itself that, as it would certainly not have reached the same conclusion, the Tribunal which did so was 'certainly wrong'. Furthermore, the more dogmatic the temperament of the judges concerned, the more likely that are to take this view. However, this is a classic non sequitur. It does not matter whether, with whatever degree of certainty, the appellate court considers that it would have reached a different conclusion. What matters is whether the decision under appeal was a permissible option. To answer that question in the negative in the context of employment law, the EAT will almost always have to be able to identify a finding of fact which was unsupported by any evidence or a clear self-misdirection in law by the Industrial Tribunal. If it cannot do this, it should re-examine with the greatest care its preliminary conclusion that the decision under appeal was not a permissible option and has to be characterised as 'perverse'."
