"34. UnderSection 1 of the Sex Discrimination Act 1975 , a person discriminates unlawfully against a woman if on the ground of her sex he treats her less favourably that he treats or would treat a man. 35. UnderSection 63A of the 1975 Act , if a claimant proves facts from which the Tribunal could conclude in the absence of an adequate explanation that a respondent has unlawfully discriminated, the Tribunal shall uphold the complaint unless the respondent proves that he did not commit that act."
"9. … Thereafter, according to Mrs Stevenson, the attitude of her employers towards her changed. Although they had previously been perfectly cordial, they became unpleasant towards her in various ways. She alleged this was by reason of the fact that she was pregnant and that her maternity absence would cause difficulties for the Firm. She also alleged that there had been a failure to carry out a risk assessment for her which of itself would amount to unlawful discrimination."
"61. In relation to all the matters referred to above and in the light of our factual conclusions, we did not consider that the claimant had proved facts from which we could conclude that unlawful discrimination had occurred. However, we considered that in respect of the removal of Mrs Stevenson's password, such that she did not access the Firm's office computer, we were obliged to look to the Firm for an explanation for the behaviour. We considered that such an explanation had been given. The Firm had security concerns and were previously unaware of the access available to Mrs Stevenson. We concluded therefore that there had been no unlawful discrimination in that regard."
