"6.7 In December 1999, Mr Davies played a leading role in the founding of an organisation known as Club Pays the members of which were and continue to be the parent company and its subsidiaries and the purpose of which is the negotiation of supply agreements by, as Mr Davies put it "leveraging the UK specific purchasing volumes" (in other words, making use of the improved bargaining position created by the size of the various companies' total orders). Mr Davies then and ever since chaired this group and this has required his attendance at monthly meetings and conferences in addition to the conducting of various programmes and contract implementation. Within Mr Davies' written statement, this matter appeared almost as an afterthought but in the evidence and submissions the respondent sought to ascribe to it a much more pivotal role. He told us, and we had no reason to doubt, that "in the early days" this work took up 15 to 20% of his working time although the clear inference was that the proportion has greatly decreased since then. However, it was clear to us that this work was not one of the duties of his post. With at least the full agreement, and perhaps at the request, of the respondent he undertook it but it was entirely personal to him. Accordingly, when in February 2003 he left the respondent to take up a post with the parent company based in Paris, he continued to chair Club Pays precisely as before. Moreover, we were not informed of any basis on which Mr Davies might be required to carry out this role. It was entirely personal to him, was not a part of the contractual duties of his post and on the evidence before us was not even a contractual obligation at all. In fact, whilst he was employed by the respondent, the applicant as his deputy and as the respondent's representative also performed a significant amount of work in relation to Club Pays including regular attendance at meetings. However, that too would not have been a part of her contract of employment. Having said that, to the extent that Mr Davies might have had to spend additional time on work related to Club Pays that would have increased the amount of work which the applicant as his deputy would have had to perform in relation to her and his usual contractual duties."
"6.10 …Before us, the applicant compared her duties on promotion in February 2003 with those of Mr Davies not as at June 2001 but as at April 2000. In our judgment, in this regard they were substantially the same. Of course, he was the chair of Club Pays but that had never been a duty of the post. She took over responsibility for such strategic planning as was required and the implementation of such proposals as were outstanding. The extent to which Mr McGeehan participated in such matters is an issue to which we shall return but at this stage we would record our finding that this was negligible and his role purely nominal. We were satisfied that in practice the applicant did in and after February 2003 that which Mr Davies had done in and for about fifteen months after April 2000."
"7.…On the basis of the evidence placed before us, we were satisfied that the work undertaken by Mr Davies from April 2000 until the addition of further responsibilities in about June 2001 and the work undertaken by the applicant in the months after about February 2003 were the same or at least were broadly similar and if there were any differences between them – and in our judgment there seemed very little if any at all other than the chairing of Club Pays – they were not of practical importance in relation to the terms and conditions of employment. On that basis, we found that the applicant and Mr Davies, at the times to which we have referred, were employed on like work. Since it was common ground that Mr Davies had a higher grade and commensurately greater salary in addition to more favourable benefits, it followed that on the face of matters there had been a breach of the equality clause on the part of the respondent. The respondent did not contend that the variation was genuinely due to any material factor. That was an entirely proper position and certainly on the facts placed before us we were unable to identify such a factor. This complaint was well founded."
"A woman is to be regarded as employed on like work with men if, but only if, her work and theirs is of the same or a broadly similar nature, and the differences (if any) between the things she does and the things they do are not of practical importance in relation to terms and conditions of employment; and accordingly in comparing her work with theirs regard shall be had to the frequency or otherwise with which any such differences occur in practice as well as to the nature and extent of the differences."
"First, is the work of the same, or, if not, of a broadly similar nature? Secondly, if on a general consideration of the type of work involved and the skill and knowledge required to do it, the answer is that the work is of a broadly similar nature, it is then necessary to go on and consider the detail and inquire whether the differences between the work being compared are of practical importance in relation to terms and conditions of employment. At both stages a minute examination of detail and trivial differences not likely in the real world to be reflected in the terms and conditions of employment ought to be avoided. Furthermore, in considering the second question a difference between duties the man and woman being compared are contractually required to perform is relevant only insofar as it results in an actual difference in what is done in practice: It is the actual activities involved in the individual's job not the notional paper obligations that are important in ascertaining any relevant differences. In these two stages of the inquiry under section 1(4) the legal burden of proving that she is employed on like work with a man rests on the woman claimant, but if the first question is answered in her favour a practical and evidential burden of showing differences of practical importance lies [rests] upon the employers. It is only if she does manage to establish that the two questions are to be answered in her favour so that she is employed on like work with a man, that the third question on her Equal Pay Act claim arises under section 1(3), namely whether the employer can then prove that any variation between her contract and that of the male comparator is genuinely due to a material difference (other than the difference of sex) between her case and his."
" An equality clause shall not operate in relation to a variation between the woman's contract and the man's contract if the employer proves that the variation is genuinely due to a material factor which is not the difference of sex and that factor – (a) in the case of an equality clause falling within subsection 2(a) or (b) above, must be a material difference between the woman's case and the man's;"
