"... As a result of previous interlocutory hearings, and in particular that held on28 October 1988 , the Originating Applications of all applicants were listed together before us to resolve two preliminary issues, a course provided for by Rule 8(2E) of the Complementary Rules of Procedure set out in Schedule 2 to theIndustrial Tribunals (Rules of Procedure) Regulations 1985 :-
"3. Before dealing with the issues before us, we should comment upon the progress of these cases thus far. The bulk of applications were filed by mid-1986 yet it is only now that these Tribunals begin to hear them; they are, even so, only at a preliminary stage and we, from our experience of the time taken for the preparation of expert reports in equal value cases, fear that it may well take up to five years for reports to be prepared, given the number of applicants and comparators and the individual nature of each claim. By that time (given the age range of claimants) it is statistically likely that many will have died; these claims, perhaps uniquely among those in this field which have reached a Tribunal hearing, therefore illustrate the procedural difficulties which face those who seek to pursue multiple claims under English law, quite apart from the delay inherent in the pursuit of claims under the Equal Pay Act where the preparation of an independent expert's report may be required. Others far more eminent than ourselves have criticised the Act, its drafting and the "minefield" which it has created, apparently without success; we would add that it cannot be either just or right if workers have rights which are rendered virtually unenforceable because of the law's delays. We put forward, at paragraph 30 of this decision, suggestions for the future progress of these cases in the hope that they may be resolved in a more sensible, and just, timescale."
"I cannot leave this case without adding a word about the procedures involved in equal value claims under section 1(2)(c) of the Act of 1970. If such a claim is referred to an expert under section 2A, the expert's job evaluation and the subsequent procedural steps which follow the presentation of his report under the special rules of procedure governing equal value claims in Schedule 2 to theIndustrial Tribunals (Rules of Procedure) Regulations 1985 will involve a lengthy, elaborate and, I apprehend, expensive process. The larger the number of comparators whose jobs have to be evaluated, the more elaborate and expensive the process is likely to be. Here, as already mentioned, the appellant spread her net very widely by claiming equality with eleven comparators. But by the time the case reached the House, your Lordships were told that, if her appeal succeeded, she would only seek a reference to an expert in relation to four of the original comparators. This only goes to show what a lot of time and money would have been wasted if the matter had proceeded on a reference to an expert with respect to all the eleven comparators. I do not in any way criticise the industrial tribunal in this case for deciding under section 2A(1)(a) that they could not be satisfied that there were no reasonable grounds for determining her work to be of equal value with any one of the comparators. But i think that industrial tribunals should, so far as possible, be alert to prevent abuse of the equal value claims procedure by applicants who cast their net over too wide a spread of comparators. To take an extreme case, an applicant who claimed equality with A who earns £X and also with B who earns£2 X could hardly complain if an industrial tribunal concluded that her claim of equality with A itself demonstrated that there were no reasonable grounds for her claim of equality with B."
"The proper construction of section 1(6) has given rise to a considerable difference of opinion in the course of this litigation. I do not find this surprising, because as a piece of drafting this subsection, and indeed other parts of the Act, do not possess the clarity which one might have hoped for and expected. The statute is concerned with terms and conditions of work of employees and should be drafted with that clarity which would enable both sides to a contract of employment to know without difficulty what their rights are."
"It seems to me, first, that the language of the subsection is clear and unambiguous."
"Otherwise either the woman or the man, or both, might be a `rogue' enjoying uncommon terms and conditions of employment, possibly because of the particular establishment in which they work."
"But if the time does come for fresh or amending legislation in this field of modern employment law then I have no doubt that the opportunity should be taken to improve and clarify the Act of 1970."
"On the true construction of the subsection, the issue is whether common terms and conditions apply across the relevant establishments, that is, whether the terms and conditions for the person performing the particular job done by the applicant differ according to the establishment at which that person is employed, and whether the terms and conditions of the persons do the job of the male comparables differ according to the establishments at which they are employed. In other words are the terms and conditions applicable to the relevant jobs irrespective of the establishment at which the employees work?"
"It follows therefore that section 1(6) is directed not to a comparison of the terms of the applicant and the male comparables. Rather it is directed to whether a person doing a specific job receives different terms and conditions by reason of the establishment at which, he or she is employed, or whether as in the present case, the terms and conditions are common in the sense that they are the common product of the same collective agreement of general application and do not differ according to the particular establishment. ..."
"that in making the comparison between the terms and conditions observed at establishment "X" and establishment "Y" in respect of each relevant class, the test is that they should be substantially the same, "differences de minimis" being ignored. This seems to us to accord with May LJ in Leverton as approved by Lord Bridge."
"(1)The contract of employment of a mine worker is governed by a composite of collective agreements made between the respondents and either the National Union of Mineworkers of the Union of Democratic Mineworkers at national, area and pit level."
"Thus, in these cases, we must decide:- (i)what was or were the reason(s) for the admitted differences in benefits received by the applicants and their comparators?
"Once you detect that there has been a misdirection, and particularly that there has been expressed misdirection of law, the next question to be asked is not whether the conclusion of the Tribunal is plainly wrong, but whether it is plainly and unarguably right notwithstanding that misdirection. It is only if it is plainly and unarguably right notwithstanding the misdirection that the decision can stand. If the conclusion was wrong or might have been wrong, then it is for an appellate tribunal to remit the case to the only tribunal which is charged with making findings of fact."
"(xi)So far we have dealt with the position of mineworkers. We now turn to the position of other workers. The 1948 Ancillary Workers' Agreement, concluded between the respondent and the NUM, provided for specified groups to be conditioned either to agreements of a specified industry or [provided for their treatment in another way. Coke by-product workers and briquetting workers then employed on colliery premises and governed by coal mining wages agreements were to be dealt with by a dedicated scheme (former) and by a yet to be negotiated scheme (latter). `Other categories', generally described as `ancillary workers' and which, by schedule attached, included chauffeurs, gardeners, telephone operators and lorry men (all `if not employed on or about the colliery premises') were expressly to be dealt with by reference to outside conditions appropriate to their industry or, if no such conditions could be found, by separately negotiated conditions to be concluded `without relating them to the coalmining industry'. We heard evidence, which we accepted, to the effect that the workers affected by the then disociation of ancillary workers from the coalmining industry agreements were predominantly men.
"(a)They were paid differently because they were part of separate pay structures as a result of different negotiations with different unions. There was no evidence before us of the actual pay differences. (b)The evidence put before us by the respondent explained, by reference to the existence of the separate structures, why the pay difference exists. That same evidence, however, did not prove to the required standard the presence of a justification for the existence of those separate pay structures sufficient to displace the inference of discrimination which appeared to us to arise in these cases, as it had in the cases of the canteen workers in comparison with the surface mineworkers; the respondent has therefore failed to establish a genuine material factor defence to the claims of canteen workers for equal pay with clerical workers. Their claims must therefore be referred to an independent expert for evaluation."
"It seems to us as likely that the difference was due to an ingrained approach, based upon sex, which meant that women, whatever they did, would not be classed or categorised as surface mineworkers. It may well be that that approach has been condoned - even encouraged - by the NUM in the past, but it does not now prevent these applicants from taking appropriate complaint under the equal value legislation.
"With the abolition of the Wages Council in 1976 a new agreement was reached with regard to canteen workers, expressly continuing the dissociation of their terms and conditions from those of mineworkers. Other groups were still dealt with under outside Wages Councils or separate agreements: there was no sexually discriminatory reason for the treatment of the canteen workers in 1976/77."
