“On19 May 1990 the European Court of Justice delivered judgment in Barber v Guardian Royal Exchange Assurance Group (Case – C262/88)[1991] 1 QB 344 , holding that the direct effect of Article 119 made it unlawful discrimination within the community for pension schemes to provide for different NPAs for men and for women. But the Court of Justice held that (because of the absence of any sufficiently clear prior jurisprudence) the direct effect of Article 119 could not be relied upon to claim a pension entitlement by reason of that discrimination with effect prior to the publication of that decision on17 May 1990 . Subject to that restraint upon retroactivity, imposed in part because of concerns expressed by the United Kingdom as to the large financial consequences for pension schemes which commonly discriminated between men and women in that way, the Court held that it was for national courts to apply Article 119 so as to safeguard the equal treatment right in relation to pensions thereby conferred.”
“… employers and pension trustees may take effective measures available to them under domestic law (including the terms and rules of the relevant Scheme) to implement Article 119 by levelling down, that is reducing the rights of the advantaged class to those of the disadvantaged class, with respect to future pensionable service (i.e. service undertaken after the taking of those effective measures). But in relation to the period from the opening of the Barber window until the taking of those effective measures (generally described as the closing of the Barber window) employers and trustees will be required to confer the same rights upon the disadvantaged class as those enjoyed by the advantaged class…”
“1. Each Member State shall during the first stage ensure and subsequently maintain the application of the principle that men and women should receive equal pay for equal work. 2. For the purpose of this article, “pay” means the ordinary basic or minimum wage or salary and any other consideration, whether in cash or in kind, which the worker receives directly or indirectly, in respect of his employment, from his employer.”
“It follows that until such time as the national government adopts the necessary implementing measures, women are entitled to be treated in the same manner, and to have the same rules applied to them, as men who are in the same situation since, where the directive has not been implemented, those rules remain the only valid point of reference.”
“... where there is indirect discrimination in a clause in a collective wage agreement, the class of persons placed at a disadvantage by reason of that discrimination must be treated in the same way and made subject to the same scheme, proportionately to the number of hours worked, as other workers, such scheme remaining, for want of correct transportation of article 119 of the EEC Treaty into national law, the only valid point of reference.”
“31 Moreover, in paragraphs 18 to 20 of its judgment of7 February 1991 inCase C-184/89 Nimz v Freie und Hansestadt Hamburg[1991] ECR I-297 the Court held that the national court must set aside any discriminatory provision of national law, without having to request or await its prior removal by collective bargaining or by any other constitutional procedure, and to apply to members of the disadvantaged group the same arrangements as those enjoyed by the other employees, arrangements which, failing correct implementation of Article 119 in national law, remain the only valid point of reference. 32 It follows that, once the Court has found that discrimination in relation to pay exists and so long as measures for bringing about equal treatment have not been adopted by the scheme, the only proper way of complying with Article 119 is to grant to the persons in the disadvantaged class the same advantages as those enjoyed by the persons in the favoured class.”
“9. … In my joint opinion of28 April 1993 in Ten Oever v. Stichting Bedrijfspensioenfonds voor het Glazenwassers -en Schoonmaakbedrijf (Case C-109/91 ) and other cases [1995] I.C.R. 74, 128-129, point 60, taking the court’s case law as my basis, I drew a distinction between pension benefits according to whether they were based on discrimination occurring in the past (after the judgment in Barber v. Guardian Royal Exchange Assurance Group (Case C-262/88 ) [1990] I.C.R. 616) or they were related to service performed after the introduction of new rules adapted to the principle of equal treatment as a result of that judgment. That distinction must also be maintained in the present cases. 10. As regards benefits based on periods of service completed in the past to which discriminatory rules applied, it is necessary, pending rules to abolish such discrimination, to increase the level of benefits of the disadvantaged sex so as to bring it up to that of the advantaged sex. In cases involving sex discrimination the court has consistently held that the more favourable rules must be applied to the less favoured sex, those rules forming “the only valid frame of reference” for immediate implementation of the principle of equal treatment. … 11. The situation is fundamentally different so far as concerns benefits based on new rules adapted to the principle of equal treatment and relating to future periods of service, that is to say periods completed after the entry into force of the rules. I share the view taken by Avdel Systems Ltd., the United Kingdom, the German Government and the Commission that Community law does not preclude a lowering of such benefits so long as those benefits are set at a level which is the same for both men and women. Any different conclusion would amount to undesirable Community interference in a policy area which at present is the province of the member states, which, as the court has consistently ruled, “enjoy a reasonable margin of discretion as regards both the nature of the protective measures and the detailed arrangements for their implementation:”
“leaves intact . . . the powers reserved by articles 117 and 118 of the Treaty to the member states to define their social policy within the framework of close co-operation organised by the Commission, and consequently the nature and extent of measures of social protection, including those relating to social security, and the way in which they are implemented.”
“the date that measures which are fully legally enforceable are taken to equalise the NPA of men and women. Such measures are to be embedded in a legal regime that complies with Article 47 of the Charter of Fundamental Rights of the European Union and Article 19(1) TEU.”
“24 Having regard to the direct effect of art.119 of the EC Treaty, the application of that provision by employers, once discrimination has been found to exist, must be immediate and full, and therefore measures taken with a view to reinstating equal treatment cannot, as a rule, be made subject to conditions which maintain discrimination, even on a transitional basis (see, to that effect, Avdel Systems [1995] 3 C.M.L.R. 543 at [25] and [26]). 25 Furthermore, the principle of legal certainty must also be observed. That latter principle, which must be observed all the more strictly in the case of rules liable to entail financial consequences, requires that the rights conferred on individuals by EU law must be implemented in a way which is sufficiently precise, clear and foreseeable to enable the persons concerned to know precisely their rights and their obligations, to take steps accordingly and to rely on those rights, if necessary, before the national courts. The introduction of a mere practice, which has no binding legal effects with regard to the persons concerned, does not meet these requirements (see, to that effect, Aventis Pasteur SA v OB (C-358/08) EU:C:2009:744; [2010] 2 C.M.L.R. 16 at [47], and Euro Park Service v Ministre des Finances et des Comptes publics (C-14/16) EU:C:2017:177; [2017] 3 C.M.L.R. 17 at [36]–[38], [40] and [42] and the case law cited). 26 Thus, in order to be capable of being regarded as reinstating the equal treatment required by art.119 of the EC Treaty, the measures adopted with a view to ending discrimination contrary to that provision must satisfy the requirements set out at [24] and [25] above.”
“Furthermore and above all, it must be pointed out that any measure seeking to eliminate discrimination contrary to EU law constitutes an implementation of EU law, which must observe its requirements. In particular, neither national law nor the provisions of the Trust Deed governing the pension scheme concerned can be relied upon in order to circumvent those requirements.”
“It would be contrary to that objective, to the principle of legal certainty and to the requirements set out at [17], [24] and [34] above to allow the authorities with responsibility for the pension scheme concerned to eliminate discrimination contrary to art.119 of the EC Treaty by adopting a measure equalising, with retroactive effect, the NPA of the members of that scheme to the NPA of the persons within the previously disadvantaged category. To accept such an approach would relieve those authorities of the obligation, after the finding of discrimination, to eliminate it immediately and in full. Moreover, it would fail to comply with the obligation to grant the persons within the previously disadvantaged category enjoyment of the NPA of the persons within the previously favoured category so far as concerns the pension rights relating to the periods of service between the date of delivery of Barber [1990] 2 C.M.L.R. 513 and the date of the adoption of the measures achieving equal treatment, and with the prohibition on removing, with retroactive effect, the advantages of the latter persons. Lastly it would, until the adoption of such measures, create doubts, contrary to the principle of legal certainty, as regards the scope of the rights of the members.”
“(1) The trustees or managers of an occupational pension scheme may, if— (a) they do not (apart from this section) have power to make such alterations to the scheme as may be required to secure conformity with an equal treatment rule, or (b) they have such power but the procedure for doing so— (i) is liable to be unduly complex or protracted, or (ii) involves the obtaining of consents which cannot be obtained, or can only be obtained with undue delay or difficulty, by resolution make such alterations to the scheme. (2) The alterations may have effect in relation to a period before the alterations are made.”
“It is clear that under section 62 the rules of the scheme are to be read as modified so as to conform with Article 119…”
