Reference from France by the Cour de Cassation (Supreme Court) under Article

177 EEC. Social security. Discrimination. Substantive and procedural differences between the social security systems of individual member-States, and hence in the rights of workers employed in them, are unaffected by Article 51 EEC. But the Community rules on social security introduced pursuant to Article 51 must refrain from adding to the disparities which already stem from the absence of harmonisation of the national laws. [20]-[21] Social security. Discrimination. Family allowances. Article 73(2) of Regulation 1408/71 (which provides an exceptional rule for the payment of family benefits to workers subject to French legislation) is invalid in so far as it precludes the award to employed persons subject to French legislation of French family benefits for members of their family residing in another member-State. [25] European Court. Judgments. Prospective overruling. Social security. Where the European Court in the course of Article 177 proceedings holds a Community measure to be invalid and makes use of its power of prospective

overruling (permissible when there are overriding considerations of legal certainty involving all the interests at stake, both public and private), it will itself decide whether the judgment will have effect as from immediately after its delivery or from a prior date so as to cover also the instant proceedings. [29] Societe des Produits de MaÏs SA v. Administration des Douanes et Droits Indirects (112/83): [1985] E.C.R. 719, explained. The Court interpreted Articles 48 and 51 EEC and Article 73 of Regulation 1408/71 in the context of an Italian worker resident and *351 working in France whose wife and children went to Italy for an extended visit (more than three months) such that they lost their status as French residents under French social security law and lost for that period their entitlement to French family allowances, to the effect that Article 73(1) laid down a general rule that family allowances should be paid by the country of residence of the worker, that Article 73(2) made a special exception in the case of France whereby French family allowances would not be paid for families resident in other member-States and the latter States would be responsible for paying them, that the effect of Article 73(2) discriminated against migrant workers in France since they were more likely than French workers to have foreign connections and therefore to have their families abroad either temporarily or for a long time, that consequently Article 73(2) was invalid as conflicting with Article 48 EEC, that the present judgment would have only prospective effect and that such prospecive effect would include the present plaintiff and any other employed persons who had already brought legal proceedings or made an equivalent claim prior to the date of this judgment but that otherwise the judgment could not be relied on to support claims regarding benefits for periods prior to that date.

Opinion of the Advocate General (Sig. Federico Mancini)

1 The French Cour de Cassation (Court of Cassation) asks the Court to interpret, in connection with proceedings pending between Pietro Pinna and the Caisse d'Allocations Familiales de la Savoie (Family Allowances Fund, Savoie), Article 73(2) of Council Regulation 1408/71 on the application of social security schemes to employed persons and their families moving within the Community. That Article provides that: 'A worker subject to French legislation shall be entitled, in respect of members of his family residing in the territory of a member-State other than France, to the family allowances provided for by the legislation of the member-State in whose territory those members of the family reside; the worker must satisfy the conditions regarding employment on which French legislation bases entitlement to such benefits'. In particular the court making the reference wishes to know whether the provision is still valid and effective and how the concept of residence referred to therein is to be interpreted.

2 Pietro Pinna, an Italian national, works and resides, together with his family, in France, where he receives French family benefits. In Autumn 1977 his wife and two children travelled to Italy, his son, the elder of the two children, returning to France on 31 December 1977, his wife and daughter on 31 March 1978. In view of that stay in Italy the Caisse d'Allocations Familiales de la Savoie (hereinafter referred to as 'the Fund') refused to pay Mr. Pinna the benefits payable for his son in respect of the period from 1 October to 31 December 1977 and for his daughter in respect of *354 the period from 1 October 1977 to 31 March 1978. The Fund considered, in fact, that, as a result of Article 73(2) of Regulation 1408/71 (quoted above), the family allowances had to be paid by the Italian social security institution (Istituto Nazionale della Previdenza Sociale) at the place where the two dhildren had resided in Italy (L'Aquila). Following an unsuccessful appeal against that decision before the Commission des Recours Gracieux (Appeals Committee) Mr. Pinna instituted proceedings before the Commission de Première Instance du Contentieux de la Sécurité Sociale (Social Security First Instance Appeals Board), Chambéry. However, by judgment delivered on 6 January 1981 the Board dismissed his application on the ground that his situation was expressly covered by Article 73(2) and that the Fund had simply applied that provision. By judgment of 15 May 1981 the Cour d'Appel (Court of Appeal), Chambéry, upheld the Board's judgment. Consequently Mr. Pinna appealed to the Cour de Cassation on the following grounds.

(a) Under the French legislation i force Mr. Pinna's two other children were to be deemed to be resident in France. According to section L 511 of the Code de la Sécurité Sociale (Social Security Code) any French or foreign national residing in France who has one or more dependent children residing in France is entitled in respect of those children to the family benefits which are listed in section L 510. Moreover, as a result of sections 2 and 6 of Decree 46-2880 of 10 December 1946 (as amended by Decree 78-378 of 17 March 1978 and Decree 65-524 of 29 June 1965 respectively) a child who, while maintaining family ties in France, where he has hitherto resided, stays outside that country on one or more occasions so that the total duration does not exceed three months in any one calendar year is deemed to reside in France. (b) Article 73(2) of Regulation 1408/71 constitutes a special derogation from the principle set out in Article 73(1) according to which: 'A worker subject to the legislation of a member-State ... shall be entitled to the family benefits provided for by the legislation of the first member-State for members of his family residing in the territory of another member-State, as though they were residing in the territory of another member-State, as though they were residing in the territory of the first State'. The anomalous nature of the contested provision is borne out by Article 98 (now Article 99) of Regulation 1408/71, which provided that before 1 January 1973 the Council should, on a proposal from the Commission, re-examine the problem of family benefits for members of the family who are not residing in the territory of the competent State, in order to reach a uniform solution *355 for all member-States. Therefore, since the Council failed to enact any legislation by that date, Article 73(2) is to be deemed to have lapsed and the principle laid down in Article 73(1) applies to all workers subject to the legislation of a member- State of the Community, including those subject to French legislation. (c) Article 73(2) discriminates doubly against non-French workers subject to French legislation, first as compared with French workers and secondly as compared with workers subject to the legislation of a member-State other than France. It therefore breaches the principle of non-discrimination expressed in Articles 7, 48 and 51 of the EEC Treaty. (d) Since the two children are resident in France and no evidence has been found capable of disproving that fact, Article 73 does not apply to the specific situation of Mr. Pinna's children. The Cour de Cassation considered that in order to resolve the dispute it was essential to have a ruling of the Court of Justice on the validity and interpretation of a provision of Regulation 1408/71. Accordingly by judgment of 11 January 1984 it stayed the proceedings and asked the Court to give a preliminary ruling pursuant to Article 177 EEC on: (a) the validity and continued applicability of Article 73(2) of Regulation 1408/71 and (b) the inerpretation of the expression 'residence' in the context of that provision.

3 In order to appreciate fully the scope of the two questions it is necessary to consider the legislation to which they refer in greater depth. Article 40 of Council

Regulation 3 of 25 September 1958 concerning social security for migrant workers provided that: 'A wage-earner or assimilated worker who is employed in the territory of one member-State, and has children who are permanently resident or are being brought up in the territory of another member-State. shall be entitled, in respect of such children, to family allowances according to the provisions of the legislation of the former State, up to the amount of the allowances granted under the legislation of the latter State.' However, thirteen years later Regulation 1408/71 recast that provision by eliminating the restrictions of family allowances to the amount granted under the legislation of the member-State in which the members of the worker's family are resident and by extending the worker's entitlement to cover the whole range of family benefits. Indeed, as I have already pointed out, Article 73(1) of Regulation 1408/71 provides that: 'A worker subject to the legislation of a member-State other than France shall be entitled to the family benefits *356 provided for by the legislation of the first member-State for members of his family residing in the territory of the first State'. Consequently that provision constituted a substantial improvement; yet it was defective, since the Council was not unanimous in providing that it should apply throughout the Community. That is the reason for the reservation in favour of France which appears in Article 73(1) and, in conjunction therewith, for Article 73(2) which provides that a worker employed in France is entitled, in respect of members of his family residing in another member-State, to family allowances only and solely to those allowances provided for by the legislation of the member-State in whose territory those members of the family reside. As a result of Article 75(2) the allowances are paid by the social security institution of the place of residence of the members of the family, which is subsequently reimbursed in full by the institution from which the worker claims entitlement to benefit. Hence under the system set up by the regulation France is still liable but it pays the allowances at the rate in force in the country of residence and, unlike all the other member-States, does not export the whole range of family benefits. However, the member-States themselves considered that the resultant dual system should be superseded, and in Article 98 (now Article 99) of Regulation 1408/71 they determined that within two years the Council should, on a proposal from the Commission, take steps to amend it. In the result, the Commission played its part: it submitted an initial proposal on 10 April 1975, [FN1] which was followed on 15 January 1976 by the submission to the Council of a second proposal taking into account the amendments suggested by the Economic and Social Committee [FN2] and by the European Parliament. [FN3] The proposal recommended that there should be a single system for the grant of family benefits and that the general criterion for co-ordination to be adopted to that end should be the law of the State in which the worker was employed. That proposal remained on the agenda for several Council meetings and was most recently considered at the informal Council meetings held in September and November 1983. Yet again, however, it was not possible to come to a unanimous decision in accordance with Article 51 of the Treaty.

4 Following the order adopted in the questions referred for a preliminary ruling I shall deal first with the question of the validity of Article 73(2) of Regulation 1408/71 by reference to the principle of non-discrimination expressed in Articles 7, 48 and 51 of the Treaty. The Council, the Commission and the Fund consider that *357 the answer should be in the affirmative (the provision is valid). In contrast, the Italian and Greek Governments and the appellant in the main proceedings contend that, contrary to the Treaty, Article 73(2) discriminates against nationals of other member-States working in France and should therefore be declared invalid. As has already been pointed out in the description of Mr. Pinna's grounds of appeal, the alleged discrimination is double, first with respect to workers subject to the legislation of a member-State other than France and secondly with respect to French workers employed in France. Obviously those submitting observations to the effect that the provision at issue is valid contest that argument, although each of them deploys different arguments for the two forms which, according to those holding the opposite view, the alleged discrimination takes. Let us consider therefore those arguments, beginning with the alleged discrimination between a Community worker employed in France and a Community worker working in one of the other member-States. In the view of the Commission, the French Government and the Fund, that discrimination is not covered by the prohibition laid down in Article 7 of the Treaty. They argue that that discrimination is the result of the continuing differences as between the national social security systems. They maintain that such differences are inevitable, since, as the Court has consistently held, Article 51 EEC and Regulation 1408/71 simply co-ordinate the laws of the ten States and do not aim in any way to harmonise them (see, inter alia, the judgments in Case 100/78, Rossi v. Caisse de Compensation pour Allocations Familiales des Regions de Charleroi et Namur [FN4] and Case 733/79, Caisse de Compensation des Allocations Familiales des Regions de Charleroi et Namur v. Laterza [FN5]). The Commission and the Fund argue in addition that those differences would not disappear if the provision at issue were to be replaced by a system based on the lex loci laboris: even a worker to whom Article 73(1) applies experiences a fall in benefits when he moves from a member-State in which the amount of benefits is high to one which grants a smaller amount of benefits. FN4 [1979] E.C.R. 831, [1979] 3 C.M.L.R. 544. FN5 [1980] E.C.R. 1915, [1981] 1 C.M.L.R. 158.

The Council goes further. It contends that the discrimination in question is not so much inevitable as non-existent in view of the non-comparability of the situation of a non-French worker employed in France with that of one employed in another member-State. The Community citizen who has decided to work in a country other than his own is, in the Council's view, bound to accept the consequences of the exercise of the freedom of movement. That is to say, it is for him to find out about the advantages and drawbacks of the decision which he is about to take above all as regards tax, social security and education: if he does not or if, after making *358 inquiries, he opts for a country with a less favourable system he cannot subsequently claim to be the victim of discrimination and maintain perhaps that the system to which he became subject discourages the free movement of workers. However, the Council, together with the French Government and the Fund, also concedes that the choice of the law of the State of residence as determining the type and amount of the benefits due in respect of the members of the family of a Community worker employed in France who are not resident in that country results in real and avoidable differences in treatment compared with other systems. But, it is argued, that does not mean that those differences are unlawful. That choice falls within the Council's discretion to implement Article 51 of the Treaty by 'means which, viewed objectively, are justified': a power which the Court held the Community legislature to possess in Case 19/76, Triches v. Caisse de Compensation pour Allocations Familiales de la Region Liegeoise. [FN6] In that case the Court held that Article 42(2) of Regulation 3 as subsequently amended, which provided that beneficiaries of pensions due under the legislation of several member-States were entitled to family allowances in accordance with the legislation of the country in which they were resident, was lawful. FN6 [1976] E.C.R. 1243, [1977] 1 C.M.L.R. 213. Lastly the Fund considers that Mr. Pinna's argument that Article 73(2) infringes Article 51 of the Treaty is unfounded. It contends that, far from requiring social security benefits to be exported, Article 73(2) simply requires the payment of social benefits to be ensured regardless of where the dependants reside. Let us now turn to Mr. Pinna's alleged second discrimination, namely that allegedly introduced by Article 73(2) between a non-French worker employed in France with children resident abroad and a French or migrant worker with children resident in France. The French Government, the Fund and the Commission contend that that discrimination is inevitable; that is to say, in this case too any disparities in the treatment of the various interested parties are due to the continuing differences between the laws of the member-States. As a result, if a non-French worker employed in France with children resident abroad receives less benefit than he would in France he must attribute that disadvantage, not to Article 73(2), but to the fact that the amount of allowances differs under French law and under the law of the member-State of residence. In any event, it is argued, those differences are not contrary to Article 51 of the

Treaty. Article 51 would be infringed if the differences in benefits were linked to the movement of workers; in this case, however, the differences are due to the movement of members of their families, which is not protected by Community law. *359 Once again the Council takes a stricter line: in its view there is no discrimination. On the contrary, it holds that the regulation favours the migrant worker in so far as it grants him in any event the allowances granted in the country of residence whereas under French law a French citizen whose children remain abroad for more than three months in any given calendar year ceases to be entitled to family allowances. Moreover, the Council reiterates that as regards foreign workers employed in France with children resident in other States and those whose children reside in France their situations are not comparable in view of their differing requirements in point of housing, education and maintenance. Even if that were not so, however, the resulting discrimination would not infringe the Treaty or, in particular, Article 48(2) thereof. Article 48(2) is concerned that the system adopted by the Community legislature should not discriminate on the basis of nationality: the system at issue certainly is not based on the nationality of the worker but on the place in which the members of his family reside.

5 Before considering the arguments summarised above it is worth setting out the principles against which Article 73(2) must be tested, namely those governing the free movement of labour and social security. Indeed the fifth recital in the preamble to Regulation 1408/71 states that a primary objective of the legislation is to 'contribute towards the improvement of ... [the] standard of living and conditions of employment, by guaranteeing ... firstly equality of treatment for all nationals of Member States under the various national legislations and secondly social security benefits for workers and their dependants regardless of their place of employment or of residence.' Accordingly, Article 3(1) of the regulation provides, under the heading ' Equality of treatment', that: 'Subject to the special provisions' of the regulation persons resident in the territory of one of the member-States to whom the regulation applies 'shall be subject to the same obligations and enjoy the same benefits under the legislation of any member-State as the nationals of that State.' As the judgment in Case 1/78, Kenny v. Insurance Officer [FN7] states, the intention was to ensure, parallel with Article 48 of the Treaty and pursuant to Article 7 of the Treaty, 'equality in the area of social security without distinction as to nationality, by prohibiting any discrimination in such matters arising from the national legislation of member-States.' The use of the adjective 'any' in that extract seems to me to be particularly important. Since it is of a general nature and conditions the operation of the Community *360 system the principle of non-discrimination must in fact be understood in a broad sense: accordingly it also prohibits covert discrimination, that is to say discrimination arising because of the adoption of criteria other than nationality (Case 61/77, E.C. Commission v. Ireland [FN8]; Case 152/73, Sotgiu v. Deutsche Bundespost [FN9]; Joined Cases 62-63/81, Seco SA and Desquenne & Giral SA v. Etablissement D'Assurance

contre la Vieillesse et L'Invalidite [FN10]). FN7 [1978] E.C.R. 1489, [1978] 3 C.M.L.R. 651. FN8 [1978] E.C.R. 417, [1978] 2 C.M.L.R. 466. FN9 [1974] E.C.R. 153. FN10 [1982] E.C.R. 223. The principle of non-discrimination in the social security field is closely linked with the determination of the legislation applicable to the social security treatment of the worker and of the national legislation of the State whose institutions are under a duty to pay the relevant benefits. The relevant general rule is set out in Article 13 of Regulation 1408/71: a person to whom the regulation applies must be subject to the legislation of a single member-State only, which is to be determined generally on the basis of the locus laboris. It will be observed that Article 73(1), quoted above, is a specific application of that principle. In any case, the principle corresponds to the principle adopted in employment legislation and, as far as social security is concerned, it is justified by the territorial nature of social security legislation. Indeed it is logical to entrust the administration of social security contributions and benefits to the social security institutions of the country of employment. However, as I have already remarked, Regulation 1408/71 should also be interpreted in the light of social security principles (Article 51 EEC) and, more generally, 'in the light of the spirit and of the objectives of the Treaty' (Case 17/76, Brack v. Insurance Officer [FN11]). Indeed, the Court has repeatedly stressed in that connection that 'the aim of Articles 48 to 51 ... would not be attained but disregarded if the worker were obliged, in order to avail himself of the freedom of movement ..., to find himself subjected to the loss of rights already acquired in one of the member-States without having them replaced by at least equivalent benefits' (Case 100/63, Kalsbeek (Van der Veen) v. Bestuur der Sociale Verzekeringsbank [FN12]; Case 92/63, Nonnenmacher v. Bestuur der Sociale Verzekeringsbank [FN13]; Case 34/69, Caisse D'Assurance Vieillesse des Travailleurs Salaries de Paris v.

Nevertheless the concept has been further refined and elucidated, first in Case 19/76, Triches, already mentioned (where the Court held that: 'The measures taken ... pursuant to Article 51 must not have the effect of depriving a migrant worker of a right acquired by virtue only of the legislation of the member-State in which he has worked'), and subsequently in a series of judgments on the provisions prohibiting overlapping, where Regulation 1408/71 uses the criterion of the State of residence for the purpose of the payment of family benefits which are due concurrently under the law of the State of residence and that of the State of employment (Case 100/78, Rossi, Case 733/79, Laterza, both already mentioned; Case 807/79, Gravina [FN17]; Case 104/80, Beeck v. Bundesanstalt für Arbeit [FN18]; Case 320/82, D'Amario v. Landesversicherungsanstalt Schwaben [FN19]). FN17 [1980] E.C.R. 2205, [1981] 1 C.M.L.R. 529. FN18 [1981] E.C.R. 503, [1982] 2 C.M.L.R. 663. FN19 [1983] E.C.R. 3811. Those cases confirm that the Community legislature may not deprive workers of a right obtained by virtue only of the legislation of the State in which they were employed. The upshot is that where family benefits are granted under the legislation of more than one member-State, the provision of the regulation providing that the benefits of the country of residence must be paid cannot override the right to a greater amount of benefit which has arisen in the country or employment; the claimant must therefore be paid, if not the whole of that benefit, the amount by which that benefit exceeds the benefit payable in the country of residence. In other words, in order to obviate unwarranted overlapping, the regulation may suspend the payment of benefits in one of the two member-States but not the payment of the amount in excess of the benefit to which the worker is entitled in the other member-State.

6 On the basis of the principles mentioned and of the interpretation given by the Court I consider that I can show that the arguments to the effect that the provision at issue is valid are unfounded. My reasons for that conclusion are as follows.

A I shall commence, as in section 4 above, with the difference in treatment

between a worker employed in France and a worker employed in one of the other member-States. The arguments which have been advanced with regard to that point by all those who have submitted observations have the merit of bringing out, with all its ramifications, the conflict underlying *362 the choice between the criterion of the country of employment and the criterion of the country of residence as regards the grant of social security benefits and, especially, family benefits. As the Court is aware, the Council debated that choice at length, first when issuing Regulation 3, subsequently when recasting it by means of Regulation 1408/71 and finally following the proposal for a uniform solution which the Commission submitted to it in 1976 (see section 3 above). It would be interesting to go back over those debates but this is not the appropriate place. So it is sufficient to bear in mind that in 1971 the legislature adopted the general criterion of the country of employment and used the other criterion only where it was likely to be more practical in view of the nature of the benefit concerned or the way of determining it. In fact the latter criterion was used: (a) for sickness insurance benefits in kind provided in countries other than that of entitlement; such benefits are equivalent throughout the Community and, in any case, cannot be 'exported' physically; (b) family benefits paid to pensioners entitled to a pension under the legislation of two or more member-States; this is because of the difficulties that would arise in dividing family allowances pro rata as well; (c) some benefits granted to frontier workers. Having said that, I strongly contest the Council's contention that the discrimination which I have taken as my starting point is non-existent. As far as that contention and, in particular, the arguments raised to support it are concerned, I shall simply say that it conflicts clearly or, better, stridently with the principle that migrant workers must be treated in accordance with uniform Community rules wherever they decide to settle. Other more pungent criticism would perhaps be appropriate but, I believe, would not be consonant with the office of Advocate General. The view that the disparity in question is due solely to the differences in the legislation of the ten States, although it is more seemly, should likewise be rejected. Such differences may give rise to discrimination; the provision at issue is bound to cause discrimination. Let us examine its mode of operation. It causes the grant of family allowances to depend on a combination of laws: French law governs entitlement, whilst the character and the amount of the benefit are determined by reference to the law of the State of residence. Consequently, that reference determines the benefit and, as in the circumstances which gave rise to these proceedings, its effect is to reduce the substance of the right acquired under French law. The point is this: it is not any difference between the two laws which creates the discrimination but the way in which Article 73(2) co-ordinates those laws. It is that co-ordination which eliminates the benefit granted by virtue of the State of employment only and artificially creates another, *363 which is governed by the law of the State in which the members of the worker's family reside. Is such elimination permissible? My view is that it is not, and I base that opinion

on the Court's judgments in the Rossi, Laterza, Gravina, Beeck and D'Amario cases. Admittedly those cases concerned overlapping benefits arising under the legislation of two or more member-States, whilst in this case only one benefit is involved, although it is governed by a combination of laws. However, it is obvious that a difference of that kind cannot go so far as to prevent the principle laid down by the Court (the worker must not suffer disadvantage as a result of the place in which the members of his family reside) from applying also to the situation with which this case is concerned. Moreover, as the Greek and Italian Governments and the appellant in the main proceedings observe, if that principle were not to apply to this case we should be faced with a manifest infringement of Article 51 EEC. And I would remind the Commission and the Fund that Article 51 also mentions the dependants of migrant workers and requires benefits to be paid (and hence exported) irrespective of the member-State in which the recipients of the benefits reside. Neither let it be said that the criterion of the State of employment may also be discriminatory, where a migrant moves from a country where benefits are very high to another where benefits are lower. Two objections may be levelled against that argument. In the case of Article 73(1), which itself relies on the locus laboris, the position is different, since the benefits are lower because the worker has moved and not, as in Article 73(2), on account of the place of residence of the members of his family. Secondly, to calculate advantages and disadvantages by comparing the 'benefits' received in each case is incorrect: the calculation must take account of the fact that the worker employed in France to whom Article 73(2) applies receives 'family allowances' only whilst Article 73(1) requires all 'family benefits' to be granted in the other nine member-States.

B Let us now examine the question of discrimination between the Community worker employed in France and French nationals employed in France. It is unnecessary to answer the arguments put forward by the Commission, the Fund and the French Government, since they are no different from those criticised above. However, the Council's argument warrants two comments. First, it is not true in every case that the contested provision favours the Community worker, for under the French legislation a member of the family may stay abroad for more than three months *364 if his health or education so require. [FN20] Secondly, it is wrong to say that there is no discrimination. Discrimination is present but covert, for, as the Italian Government points out, the operation of the 'residence' parameter differs according to the worker's nationality. In other words, the family unit of a person working in his country of origin is generally united whereas the migrant worker's family is generally separated. That some members of his family should reside in countries other than the one in which he is employed is in fact a normal effect of a worker's moving within the Community. FN20 See section 6 of the decree of 10 December 1946 as amended by the decree of 17 April 1972 and by the decree of 14 May 1968 and, as regards case

law, Cassation (section sociale) 27 January 1972 and 22 March 1973 in [1972] Droit Social 530, and [1973] Droit Social 537.

C Lastly there is the question of discrimination between non-French workers employed in France, depending on whether their children live with them or abroad. As we have seen, the Council considers that that discrimination is compatible with Article 48(2) of the Treaty. In my view, it is not. By prohibiting all discrimination as regards employment, Article 48(2) is designed to apply to the whole set of conditions determining the status of the employed worker and hence to, inter alia, his social security situation. On this assumption, it is impossible to understand why, given that they pay the same social security contributions to the competent institutions and/or the same taxes to the revenue authorities of the same country, some Community workers should be treated less favourably because of the place of residence of members of their families or even, as Mr. Pinna points out, be equated to non-Community nationals without the benefit of a bilateral agreement providing for more favourable arrangements.

7 Consequently there can be no doubt as to the tendency of Article 73(2) to operate to the disadvantage of Community workers employed in France with members of their family residing elsewhere. So it remains to be established whether the choice made by the legislature comes into the category of 'means which, viewed objectively, are justified' for implementing Article 51 of the Treaty, in accordance with the Triches judgment. Let me say straight away that, in my opinion, the answer to that question must be in the negative. What justification is relied on in this case? The only justification expressly given by the legislature appears in the twelfth recital in the preamble to the regulation, which states that it is not appropriate to lay down rules common to all the member-States in *365 the case of benefits 'aimed largely at encouraging an increase in population'. That argument has, in my view, a certain plausibility but, as the Commission itself observes, the Court's judgment of 12 July 1979 has cut the ground from under it by laying down that Regulation 1408/71 'does not make any distinction between ... social security schemes ... according to whether those schemes do or do not pursue objectives of demographic policy' (Case 237/78, Caisse Regionale D'Assurance Maladie, Lille v. Palermo [FN21]). FN21 [1979] E.C.R. 2645, [1980] 2 C.M.L.R. 31, At Para. [15]. Then there are the arguments which were adduced in justification by those who supplied observations in the course of the oral and the written procedure, all of which are less plausible. For instance, in the light of the Rossi and Laterza judgments the justification relating to the nature and territorial character of the benefits is simply non-existent. Moreover, the argument that the dual system at issue protects the financial interests of the State of employment is not much

more substantial. On the one hand, the dual system does not absolve France from having to pay the benefit because it has to reimburse the State in which the members of the migrant worker's family reside. On the other, the finances of the French Republic do not seem to be threatened to such an extent as to warrant a special rule or at least to warrant such a rule's remaining in force. It is possible that the French benefits were particularly high in 1971: that is no longer the case today, as the table produced by the Commission shows. It is further argued that the mechanism of Article 73(2) encourages the free movement of labour on the ground that since the level of benefits is determined by the State of residence that affords the worker greater freedom of choice. In common with the Commission I doubt whether that gain is sufficient to justify discriminatory treatment which is incompatible per se with Community law; but above all I doubt whether the criterion of the State of residence is the only factor encouraging the free movement of labour. There is as good if not a better case for arguing that the criterion of the country of employment encourages the worker to move in order to obtain the benefits most favourable to him, irrespective of the place in which the members of his family reside. Finally, neither can it be argued that the criterion of the country of residence is fairer since it enables the level of benefits to match the cost of maintaining a family in the various States and thus makes for equality as between members of families residing in a given country. In reality, as the Italian Government quite rightly stated, none of the ten member-States tailors benefits specifically and directly to the cost of maintaining a family. Admittedly, the two tend to correspond, but that is simply a secondary effect of the principles of solidarity underlying all the rules governing employment *366 and social security. Family benefits in particular are an element supplementary to basic pay: the actual economic and social situation of the worker therefore depends on a combination of both those items. Now let us suppose that a given State offsets the low level of wages or (as actually happened in Italy) the adoption of measures restricting the impact of the cost-of-living escalator by sharply increasing family benefits; in such a situation the criterion of the country of residence would be anything but fair in its operation. On the contrary, it would have unjust and illogical effects, since a worker whose family resided in a country where lower wages were accompanied by lower benefits would lose the benefit of the offsetting measure. The same would occur in States which grant very high levels of family benefits but do not have a system of tax deductions for maintenance of dependants. If the criterion of the country of residence were applied the worker would run the risk of paying tax in full while, at the same time, receiving lower levels of benefit. In the final analysis, Article 73(2) of Regulation 1408/71 (a) discriminates against Community workers who are subject to French legislation and whose families reside in other member-States; (b) as a result conflicts with the rules laid down in the Treaty; and (c) lacks any objective justification. It should therefore be declared invalid. I recommend that the Court adopt that solution, while, naturally, attenuating its effects by means of the corrective measures which the Court has laid down, with a view to legal certainty, in a series of judgments, the most recent

being that of 27 February 1985 (Case 112/83, Societe des Produits de MaÏs SA). [FN22] FN22 [1985] E.C.R. 719.

8 There remain the other two questions put by the court making the reference, namely the present effectiveness of the contested provision and the interpretation of the concept of residence used therein. In point of fact those questions are superseded by the conclusion which I have just reached, but Advocates General are required to deal with each case in full and it is not my intention to shirk that duty. As regards the first point, Mr. Pinna contends that Article 73(2) has lapsed owing to the expiry of the period laid down in Article 98 of Regulation 1408/71, leaving the lex loci laboris (Article 73(1)) effective throughout the Community. He maintains that that interpretation is borne out by the judgments in Case 43/75, Defrenne v. SABENA (No. 2) [FN23] and Case 231/78, E.C. Commission v.United Kingdom. *367 [FN24] The argument put forward by the Italian Government is similar but more elaborate. Its representative contended that Article 98 does not simply provide for the issuing of new rules. On the contrary, the argument runs, Article 98 requires the 're-examination' of the rules in force--which was to be carried out before 1 January 1973--to supersede the dual system on which those rules were based. According to that line of reasoning, therefore, the date of 1 January 1973 constituted the final date as regards not the duration of the re-examination but the validity of the provision which was to be re-examined. For its part, the Greek Government reaches the same conclusion, arguing that Article 73(2) is not only in the nature of a derogation but is also and above all transitional. FN23 [1976] E.C.R. 455, [1976] 2 C.M.L.R. 98. FN24 [1979] E.C.R. 1447, [1979] 2 C.M.L.R. 427. In contrast, the Council, the Commission, the French Government and the Fund all reject the argument that Article 73(2) has lapsed. In their view, the disputed provision requiring re-examination is not a novelty. It appears in other Community instruments, where (as in this case), it does not imply any temporal restriction on the validity of the provision to which it refers. They argue that, as a result, Article 73(2) remains applicable until such time as it is amended or repealed. According to the Council, one reason why that should be so is that if it were without effect the result would be a legal vacuum, since Article 98 does not stipulate whether the re-examination should cause the lex loci laboris or the criterion of the State of residence to become of general application. The judgments relied on by Mr. Pinna, it is argued, are not in point. The judgment in Defrenne refers to a duty to bring about a specific result which under Article 119 EEC must be mandatorily achieved within a fixed period. As for the judgment in Case 231/78, E.C.

Commission v. United Kingdom that was concerned with ascertaining the scope of a transitional provision in the Act of Accession by which the United Kingdom became a Member of the Community. The Commission argues that, in addition, had the legislature wished the provision to apply for a limited time only it would have employed the formula used in that very connection in the Act of Accession of the Hellenic Republic, Article 48 of which provides that: 'Until 31 December 1983, the provisions of Article 73(1) and (3) ... shall not apply to Greek workers employed in a member-State other than Greece, whose family members are resident in Greece. The provisions of Article 73(2) ... shall apply by analogy to these workers.' Personally, I consider that Article 98 (now Article 99) cannot be held to have sufficient force to have caused Article 73(2) to have lapsed automatically on 1 January 1973. That view is supported by *368 the wording of the provision, which the arguments of the Italian and Greek Governments, for all their ingenuity, ignore or distort. The fact cannot be underestimated that, as far as concerned the legislature (that is to say, in practical terms the ten member-States), Article 73(2) continued to be in force on the many occasions on which the Council discussed it and during the drafting of the Treaty with Greece. From that point of view it must be admitted that the Commission's final argument simply cannot be disregarded. But we must be careful: all that is not the same as saying that Article 98 (now Article 99) is merely optional or is neutral in substance. It is not true that Article 98 may be assimilated to the numerous provisions requiring re-examination which may be found in Community legislation: the latter aim simply to ensure the 'physiological' development of the system by making provision for technical adjustments or improvements, whereas it appears from the wording of the article in question that its authors were aware that they had created a defective system which they were under a duty to put right as soon as possible. Secondly, I very much doubt whether, as the Council maintains, the solution to which the re-examination should have led was left open in 1971. I doubt it because I consider it inconceivable that the legislature could have contemplated extending to the whole Community a criterion, like that of the State of residence, which would result to a greater or lesser degree in the diminution of rights acquired under national legislation. In any event, on the assumption that the solution was left open in 1971, the reform contemplated by Article 98 ceased to be an open question on 13 July 1976, that is to say with effect from the date of the first judgment (in Triches) in which the Court made it clear that such a diminution is incompatible with Community law.

9 I shall conclude with a few words on the concept of residence. The French Government and the Fund contend that in order to define it reference must be made to the law of the competent State. The remainder of those who submitted observations (with the exception of the Council, which did not state its view on the matter) consider that the concept of residence--which is employed in, inter alia, Article 51 of EEC, which Regulation 1408/71 is intended to implement--is a Community concept.

I also hold that opinion. Indeed, the regulation does not merely refer to the concept of residence, since Article 1(h) defines it as 'habitual residence' (whereas 'stay' is defined in Article 1(i) as 'temporary residence'). Moreover, that definition corresponds to that given to the term by the Court in a number of judgments concerning social security for migrant workers. According to those *369 judgments, the concept of residence signifies a person's 'habitual or permanent centre of interests'; a person resides in a particular place if he has occupational or family ties there, and the length of his stay there is relevant only in so far as it throws light on those ties (see Case 13/73, Anciens Etablissements D. Angenieux Fils Aine v. Hakenberg [FN25] and Case 76/76, Di Paolo v. Office National de L'Emploi [FN26]). FN25 [1973] E.C.R. 935. FN26 [1977] E.C.R. 315, [1977] 2 C.M.L.R. 59. In other words, 'residence' is not based simply on a physical fact, such as that of determining a person's address; what is more important is the intention that the stay should be of a permanent character. As a result, a person may be resident in a place even if he spends only a few months there and, conversely, a long stay may not constitute residence--for instance where the person concerned extends his stay for the purposes of study, work, treatment or recreation but does not intend it to be permanent. It will be for the national court, with that in mind, to establish in the light of the case before it whether the stay of the members of the migrant worker's family in another member-State has aspects from which an intention may be inferred to transfer the centre of their interests to that country and hence to change their residence.

10 For all the above reasons I propose that the Court should answer the questions referred to it by the French Cour de Cassation by judgment of 11 January 1984 in connection with the proceedings between Pietro Pinna and the Caisse d'Allocations Familiales de la Savoie as follows: Article 73(2) of Council Regulation 1408/71 is incompatible with Aticles 48 to 51 of the EEC Treaty because it infringes the principle of non-discrimination as regards employment and social security. In view of that answer, I suggest that the Court should not give a ruling on the other questions. JUDGMENT [1] By an order of 11 January 1984, which was received at the Court on 15 February 1984, the French Cour de Cassation referred to the Court for a preliminary ruling under Article 177 EEC two questions on the interpretation of several provisions of Council Regulation 1408/71 on the application of social security schemes to employed persons and their families moving within the

Community. [2] The questions were raised in the course of proceedings concerning the refusal of the Caisse d'Allocations Familiales de la *370 Savoie (hereinafter referred to as 'the Fund') to grant Mr. Pinna family benefits for periods in 1977 and 1978. [3] Mr. Pinna, an Italian national, resides in France with his wife and their two children, Sandro and Rosetta. In 1977 the children went to Italy with their mother for an extended visit. The Fund refused to pay Mr. Pinna family benefits for Sandro in respect of the period from 1 October 1977 to 31 December 1977 and for Rosetta in respect of the period from 1 October 1977 to 31 March 1978 on the ground that the benefits should be paid by the Istituto Nazionale della Previdenza Sociale (National Social Security Institution) at Aquila, the place in Italy where the children had been staying at the material times. [4] It appears from the Cour de Cassation's order requesting a preliminary ruling that section 511 of the French Social Security Code provides that any French or foreign national residing in France who, as head of household or otherwise, has one or more dependent children residing in France is entitled in respect of those children to the family benefits which are listed in section L. 510. According to the former section 6 of Decree 46-2880 of 10 September 1946 as amended by Decree 65-542 of 29 June 1965, and section 2 of the Decree of 10 December 1946 as amended by the Decree of 17 March 1978, a child who, while maintaining family ties in metropolitan France, where he has hitherto permanently resided, stays temporarily outside that country on one or more occasions the total duration of which does not exceed three months in any one calendar year is deemed to reside in France. The decision with which these proceedings are concerned appears to be based on Article 73(2) of Regulation 1408/71, which provides that an employed person subject to French legislation is to be entitled in respect of members of his family residing in the territory of a member-State other than France, to the family allowances provided for by the legislation of the member-State in whose territory those members of the family reside; the employed person must satisfy the conditions regarding employment on which French legislation bases entitlement to such benefits. [5] In the course of an appeal brought by Mr. Pinna, the Cour de Cassation asked the Court to rule on: (1) The validity and continued applicability of Article 73(2) of Regulation 1408/71; (2) The interpretation of the word 'residence' in the context of that provision. [6] Article 73(1) of Regulation 1408/71 provides that: An employed person subject to the legislation of a member-State other than France shall be entitled to the family benefits provided for by the legislation of the first member-State, as though they were residing in the territory of another member-State, as though they were residing in the territory of the first State. *371 [7] Article 73(2), quoted above, lays down a different rule with regard to employed persons subject to French legislation where members of their families reside in a member-State other than France. [8] Article 98 (now Article 99) of Regulation 1408/71 provides that:

Before 1 January 1973 the Council shall, on a proposal from the Commission, re-examine the whole problem of payment of family benefits to members of families who are not residing in the territory of the competent State, in order to reach a uniform solution for all member-States. [9] According to the documents before the Court, the Commission submitted to the Council on 10 April 1975--somewhat late owing to the accession of new member-States--a proposal for a regulation [FN27] in which it proposed that the system of granting the family benefits of the country of employment irrespective of the country of residence of the members of the worker's family should be adopted generally. That solution was endorsed by the European Parliament (opinion of 14 October 1975) [FN28] and by the Economic and Social Committee (opinion of 24 September 1975). [FN29] The Council discussed the matter at the sessions held on 18 December 1975 and 9 December 1976 but no decision was reached. FN27 [1975] O.J. C96/4. FN28 [1975] O.J. C257/10. FN29 [1975] O.J. C286/19. [10] As regards the validity of Article 73(2), Mr. Pinna argues that the provision has the effect of reducing allowances and treating workers from Community countries who are employed in France differently from Community workers employed in the nine other member-States. He contends that there is no political, economic or legal justification for such discrimination. As regards retirement pensions the Court has ruled that Article 51 empowers the Council to confer rights on migrant workers but does not authorise it to deprive them of rights enjoyed under national legislation. Mr. Pinna argues that what is valid for retirement pensions is also valid for family benefits. The concurrent application of the law of the country of employment (conferral of entitlement) and of the law of the country of residence of the worker's family (nature and rate of benefits) is not intended to result in decreased social protection. Consequently, he contends that Article 73(2) conflicts with Article 51 of the Treaty. In Mr. Pinna's view, Article 51 introduced the principle of exportable benefits. The result is that the recipient of any cash benefit is entitled to rely on Article 51, no matter where he establishes his residence or that of his family, in order to claim that the benefits due should be paid to him in the place where he has decided that they should be paid. The partial 'non-exportability' of one type of social benefit, under Article 73(2), conflicts with the *372 general rule laid down in Article 51. By making French family benefits 'non-exportable', Article 73(2) is in breach of Article 51 of the Treaty. [11] The Fund which is the defendant in the main proceedings argues that Article 73(2) is compatible with Articles 48 and 51 of the Treaty. Article 51 provides that migrant workers must always be paid benefits. Article 73(2) ensures that the migrant worker always receives family allowances irrespective of his family's

place of residence. The institution from which payment is due and the legislation applicable to the allowances differ from those prescribed in the case of a worker coming within the scope of Article 73(1), but the worker's entitlement to receive family allowances remains intact. In the Fund's opinion, Article 73(2) is compatible with Article 7 of the Treaty, since it in no way introduces discrimination between migrant workers. There is no doubt that in some cases the migrant worker's benefits may be reduced depending on his family's chosen country of residence, but that reflects differences in national legislation, in particular as regards the amount of benefit. Accordingly, Article 73(2) itself is manifestly not a source of discrimination. As a result, the Fund argues, Article 73(2) is compatible with Community law. [12] The French Government considers that Article 73(2) is valid. Any differences of treatment resulting from that provision do not amount to discrimination contrary to Articles 7, 48 and 51 of the Treaty. The reason for the difference in treatment to the detriment of non-French workers subject to French legislation is in fact the disparities existing between the systems of family allowances in force in the various member-States. The only way of eliminating those differences of treatment would be to harmonise national social security systems. That is not the aim of Regulation 1408/71, which simply seeks to co-ordinate those systems with a view to eliminating, in the sphere of social security, obstacles to the free movement of workers. [13] The Greek Government argues that the object of Regulation 1408/71 is to secure for all employed persons moving within the Community who are nationals of member-States equal treatment under the legislation of the various member-States and the payment of social security benefits. Problems regarding the award of family benefits to employed persons subject to the legislation of a member-State other than the member-State in which their families reside should therefore be resolved uniformly throughout the Community. In the Greek Government's view, the authors of the regulation appreciated that need when they drafted Article 98. Achievement of a uniform solution, within the meaning of Article 98, consists in adopting as a criterion the worker's place of employment. The Greek Government argues that relying on the system in force at the worker's place of employment is in keeping with, on the one *373 hand, the spirit of Regulation 1408/71, which is to ensure the free movement of workers within the Community, and, on the other hand, the principle of equal treatment in matters of social security for foreign and national workers. The Greek Government considers that Article 73(2) is not justified, in so far as it does not promote equal treatment as between migrant and national workers as regards the payment of family benefits where the members of the worker's family are resident in a country other than the country of residence of the worker himself. The migrant worker must be entitled to social security benefits in accordance with the legislation to which he is subject and pursuant to which he pays contributions and taxes. [14] The Italian Government argues that Article 73(2) gives rise to discrimination on grounds of nationality between workers employed in the same country. According to a consistent line of decisions of the Court, legislation under which any move by a worker from one member-State to another results in a reduction in

his acquired rights in respect of social security is contrary to the guarantees provided by the Treaty with regard to the free movement of workers. Application of the legislation of the member-State of residence for the purpose of calculating family allowances is designed to reduce the substance of the rights acquired by the worker under French law. [15] The Commission considers that Article 73(2) is compatible with Article 51 of the Treaty. It does not deny that in certain circumstances the application of Article 73(2) may have the result that a worker whose children reside in another member-State is entitled to family allowances lower than those payable if the members of his family resided in France, or if French family allowances were extended to members of the family residing in another member-State. However, it considers that Article 73(2) does not result in discrimination contrary to the Treaty. In the Commission's view the differences observed are essentially due to the fact that Regulation 1408/71 is an instrument for attaining the objectives of Article 51 EEC by co-ordinating social security systems with a view to eliminating obstacles to the free movement of persons. [16] The Council states that the questions referred by the national court call the validity of Article 73(2) in question for two reasons. The first is that Article 73(2) is an exceptional derogation on which it was deemed necessary from the outset to impose a time limit, namely 1 January 1973. The second is that non-French workers subject to French legislation suffer two-fold discrimination as compared with French workers on the one hand and workers subject to the legislation of a member-State other than France on the other. The Council contends that such two-fold discrimination does not exist. French and foreign workers receive identical *374 allowances in France; French workers lose their right to their allowances after three months if their children are no longer resident in French territory, whilst migrant workers receive allowances under Regulation 1408/71 in respect of their children who reside in a member-State other than France. Moreover, in the Council's view, no discrimination is discernible in the way in which migrant workers are treated in two or more different member-States since the social security legislation of the member-States is merely co-ordinated. As regards social security each member-State has retained the power to determine the nature and amount of the benefits since Article 51 does not require the Council to set up a uniform social security system for the member-States of the Community. The first question [17] In order to settle the question at issue it is appropriate to point out, in the first place, that Article 40 of Council Regulation 3 of 25 September 1958 concerning social security for migrant workers [FN30] provided that a wage-earner or assimilated worker who was employed in the territory of one member-State and had children who were permanently resident or were being brought up in the territory of another member-State was to be entitled, in respect of such children, to family allowances according to the provisions of the legislation of the former State up to the amount of the allowances granted under the legislation of the

latter State. FN30 J.O. 561/58. [18] Regulation 1408/71 amended the rules relating to migrant workers' children by enlarging the range of benefits which migrant workers are entitled to claim. It entitles them to family benefits, that is to say, to 'all benefits in kind or in cash intended to meet family expenses' (Article 1(u)(i)), whereas under Regulation 3 they were entitled only to family allowances, namely 'periodical cash benefits granted exclusively by the reference to the number and, where appropriate, the age of members of the family' (Article 1(u)(ii) of Regulation 1408/71). [19] As regards a migrant worker employed in one member-State but whose family resides in another member-State, Regulation 1408/71 introduced a distinction between workers employed in France and workers employed in other member-States. Article 73(1) provides that a worker subject to the legislation of a member-State other than France is to be entitled to the family benefits provided for by the legislation of the first member-State for members of his family residing in the territory of another member-State as though they were residing in the territory of the first State. Article 73(2) provides that a worker subject to French legislation shall be entitled, in respect of members of his family residing in the *375 territory of a member-State other than France, to the family allowances provided for by the legislation of the member-State in whose territory the members of the family reside. [20] As regards the difference in treatment between workers to whom Article 73(1) applies and workers subject to the arrangements laid down in Article 73(2), it must be observed that Article 51 EEC provides for the co-ordination, not the harmonisation, of the legislation of the member-States. As a result, Article 51 leaves in being differences between the member-States' social security systems and, consequently, in the rights of workers employed in the member-States. It follows that substantive and procedural differences between the social security systems of individual member-States, and hence in the rights of workers employed in the member-States, are unaffected by Article 51 of the Treaty. [21] Nevertheless, the achievement of the objective of securing free movement for workers within the Community, as provided for by Articles 48 to 51 EEC, is facilitated if conditions of employment, including social security rules, are as similar as possible in the various member-States. That objective will, however, be imperilled and made more difficult to realise if unnecessary differences in the social security rules are introduced by Community law. It follows that the Community rules on social security introduced pursuant to Article 51 EEC must refrain from adding to the disparities which already stem from the absence of harmonisation of national legislation. [22] Article 73 of Regulation 1408/71 creates two different systems for migrant workers depending on whether they are subject to French legislation or to the legislation of another member-State. Accordingly, it adds to the disparities caused by national legislation and, as a result, impedes the achievement of the aims set out in Articles 48 to 51 of the Treaty.

[23] More specifically with regard to the assessment of the validity of Article 73(2) itself, it must be stated that the principle of equal treatment prohibits not only overt discrimination based on nationality but all covert forms of discrimination which, by applying other distinguishing criteria, in fact achieve the same result. [24] That is precisely the case when the criterion set out in Article 73(2) is used in order to determine the legislation applicable to the family benefits of a migrant worker. Although as a general rule the French legislation employs the same criterion to determine the entitlement to family benefits of a French worker employed in French territory, that criterion is by no means equally important for that category of worker, since the problem of members of the family residing outside France arises essentially for migrant workers. Consequently, the criterion is not of such a nature as to secure the equal treatment laid down by Article 48 EEC and therefore may not be employed within the context of the co-ordination of national *376 legislation which is laid down in Article 51 EEC with a view to promoting the free movement of workers within the Community in accordance with Article 48. [25] It follows that Article 73(2) of Regulation 1408/71 is invalid in so far as it precludes the award to employed persons subject to French legislation of French family benefits for members of their family residing in the territory of another member-State. [26] As regards the consequences of the invalidity of Article 73(2), it must be noted that in Case 112/83 (Societe des Produits de MaÏs SA v. Administration des Douanes et Droits Indirects [FN31]) the Court ruled that where it is justified by overriding considerations Article 174(2) EEC gives the Court discretion to decide, in each particular case, which specific effects of a regulation which has been declared void must be maintained. FN31 [1985] E.C.R. 719. [27] Since the Council has not yet reached the uniform solution required by Article 98 of Regulation 1408/71, account should be taken, exceptionally, of the fact that France has been induced to maintain for a long period practices which were consistent with Regulation 1408/71 but which had no legal basis under Articles 48 and 51 of the Treaty. [28] In those circumstances it must be held that owing to overriding considerations of legal certainty involving all the interests at stake, public and private, the payment of family benefits for periods prior to the delivery of this judgment cannot, in principle, be called in question. [29] Accordingly, when the Court makes use of the possibility of limiting the effect on past events of a declaration in proceedings under Article 177 of the Treaty that a measure is invalid, it is for the Court to decide whether an exception to that temporal limitation of the effect of its judgment may be made in favour of the party which brought the action before the national court or in favour of any other person who took similar steps before the declaration of invalidity or whether, conversely, a declaration of invalidity applicable only to the future constitutes an adequate remedy even for persons who took action at the appropriate time with a

view to protecting their rights. [30] In this case, the appropriate determination is that, except as regards employed persons who have already brought legal proceedings or made an equivalent claim prior to the date of this judgment, the aforesaid invalidity of Article 73(2) of Regulation 1408/71 cannot be relied on in order to support claims regarding benefits for periods prior to that date. [31] In the circumstances there is no need to answer the second part of the first question, concerning the continued application of Article 73(2) of Regulation 1408/71, or the second question, *377 concerning the interpretation of the word 'residence' in the context of Article 73(2). Costs [32] The costs incurred by the Government of the Hellenic Republic, the Government of the Italian Republic, the Government of the French Republic and the Council and the Commission of the European Communities, which have submitted observations to the Court, are not recoverable. As these proceedings are, in so far as the parties to the main proceedings are concerned, in the nature of a step in the action before the national court, the decision on costs is a matter for that court. Order On those grounds, THE COURT, in answer to the questions referred to it by the French Cour de Cassation by an order of 11 January 1984, HEREBY RULES: 1. Article 73(2) of Regulation 1408/71 is invalid in so far as it precludes the award to employed persons subject to French legislation of French family benefits for members of their family residing in the territory of another member-State. 2. Except as regards employed persons who have already brought legal proceedings or made an equivalent claim prior to the date of this judgment, the aforesaid invalidity of Article 73(2) of Regulation 1408/71 cannot be relied on in order to support claims to benefits for periods prior to that date.
