"We ... are satisfied that (the employers) acted genuinely out of concern for possible dangers to the unborn child, coupled with potential liability to themselves and the difficulty of making satisfactory changes in their organisations to eliminate their concern and that there were sufficient grounds for their anxiety to indicate that they would have reacted similarly to a comparable situation (whatever that might be) involving a man, or in other words that they were not simply reacting to the Applicant's pregnancy in itself."
"1 (1) A person discriminates against a woman in any circumstances relevant for the purpose 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 ..
"In relation to direct discrimination the question for consideration is always whether the Applicant was adversely treated because of her sex or because of a neutral factor. She may say she was dismissed because of her sex but an employer may say it was because of the inconvenience to the business if he continued to employ a person who was going to be absent for three to six months over a vital period. The issue of which explanation is correct has to be answered by the application of a test involving a principle. That test, whether the dismissal was on the ground of sex or some other neutral ground, is whether she has been less favourably treated than a man was or would have been treated in comparable circumstances where those relevant circumstances are not materially different. If in comparable circumstances a man would have been treated in the same way the dismissal was not on the ground of sex and there is no direct discrimination, it was because of business needs. The applicant will have failed to establish her case.
"The answer depends on whether the fundamental reason for the refusal of employment is one which applies without distinction to workers of either sex or conversely whether it applies exclusively to one sex ... It should be observed that only women can be refused employment on the ground of pregnancy and such a refusal therefore constitutes direct discrimination on the ground of sex. A refusal of employment on account of the financial consequence of absence due to pregnancy must be regarded as based, essentially, on the fact of pregnancy."
".. the dismissal of a female worker on account of pregnancy constitutes direct discrimination on grounds of sex, as is a refusal to appoint a pregnant woman: see Dekker ... on the other hand the dismissal of a female worker on account of repeated periods of sick leave which are not attributable to pregnancy or confinement does not constitute direct discrimination on grounds of sex in as much as such periods of sick leave would lead to dismissal of a male worker in the same circumstances."
"I therefore conclude that dismissal of a pregnant woman for a reason arising out of, or related to, her pregnancy can in law be, but is not necessarily, direct discrimination under section 1 (1) (a)."
"It would indeed be remarkable if the law compelled us to reach such an unjust result."
"I agree, the dismissal of a pregnant woman for a reason arising out of her pregnancy can be but is not necessarily direct sex discrimination... It will be direct discrimination if the employer did treat or would have treated more favourably a man whose relevant circumstances were not materially different, e.g. a man who needed three months absence from work due to a medical condition."
"HELD, (1) That in determining underSection 1 (1) (a) of the Sex Discrimination Act 1975 whether the Applicant had been directly discriminated on the ground of her sex the correct comparison to be made under section 5 (3) was with a hypothetical man who would also have been unavailable for work at the material time, the precise reason for the unavailability being irrelevant; and that, in the circumstances as found by the Industrial Tribunal, the Applicant's dismissal had not constituted unlawful discrimination .."
"The question is whether it is legitimate to make a comparison between the non availability of a woman by reason of expected confinement and the non availability of a man, which may or may not be for medical reasons, for the purposes of postulating relevant circumstances under section 5 (3) of the Act. If it is not legitimate then cases can be envisaged where somewhat surprising results would follow."
"The Applicant was not dismissed simply because she was pregnant but because here pregnancy had the consequence that she would not be available for work at the critical period. It is true that but for her sex she would not have been pregnant, and but for her pregnancy she would not have been unavailable then. If the "but for" test applies to that situation it must equally apply where the reason for the woman being unavailable at the critical time is that she is then due to have an operation of a particularly gynaecological nature, such as a hysterectomy. But a man may require to undergo an operation for some condition which is peculiar to males, such as an abnormal prostate. Is the "but for his sex" test to be applied so as to produce a finding of unlawful discrimination where he is not engaged because the impending operation will make him unavailable when his services are particularly required? ... The circumstances in the case of a woman due to have a hysterectomy are different from the circumstances in the case of a man due to have a prostate operation. The question is whether they are materially different, and the answer must be that they are not, because both sets of circumstances have the result that the person concerned is not going to be available at the critical time. Then it has to be considered whether there is something special about pregnancy which ought to lead to the conclusion that the case of a woman due to be unavailable for that reason is materially different from the case of a man due to be unavailable due to an unexpected prostate operation. In logic there would not appear to be any valid reason for that conclusion. It is true that pregnancy may be said to be a normal condition, not an abnormal pathological condition such as to require a hysterectomy, but the consequences of both are the same, namely unavailability of the person when particularly needed. The argument for the applicant is that when comparison is made between a pregnant woman, who is going to be unavailable on account of her confinement at the critical time, and a man, then because a man could not be available for the same reason dismissal or failure to engage the pregnant woman constitutes discrimination. The correct comparison is not with any man but with a hypothetical man who would also be unavailable at the critical time. The relevant circumstances for the purposes of the comparison required by section 5 (3) to be made is expected unavailability at the material time. The precise reason for the unavailability is not a relevant circumstance, and in particular it is not relevant that the reason is a condition which is capable of affecting only women or for that matter only men."
