OPINION OF ADVOCATE GENERAL
      KOKOTT
      delivered on 27 October 2005 1(1)
      
      Case C-212/04
      Konstantinos Adeneler and Others
      
      (Reference for a preliminary ruling from the Monomeles Protodikio Thessalonikis (Greece))
      (Obligation to interpret national law in accordance with a given directive before expiry of the period prescribed for transposition
         of that directive – Framework agreement on fixed-term work (Directive 1999/70) – Successive fixed-term employment relationships in the public sector – Objective reasons – Measures to prevent abuse)
      I –  Introduction
      1.     The present case looks at how fixed-term employment relationships are used by public sector employers in Greece. A Greek court,
         the Monomeles Protodikio Thessalonikis (Single-Judge Court of First Instance, Thessaloniki, Greece), has made a reference
         for a preliminary ruling, enquiring about the requirements of Community law applying to such fixed-term employment relationships.
         This matter focuses in particular on the measures necessary to prevent the abuse of successive fixed-term employment contracts.
      
      2.     In this case the Court of Justice also looks at a matter of fundamental significance, namely the time from which national
         courts are required to interpret national law in accordance with directives.
      
      II –  Relevant legislation
      A –    Community law
      3.     The Community legislation relevant to this case is Council Directive 1999/70/EC of 28 June 1999 concerning the Famework Agreement
         on fixed-term work concluded by ETUC, UNICE and CEEP (2) (hereinafter ‘Directive 1999/70’). The Framework Agreement on fixed-term work (hereinafter ‘Framework Agreement’), concluded
         on 18 March 1999 by three general cross-industry organisations (ETUC, UNICE and CEEP) and annexed to the directive, is implemented
         by that directive.
      
      4.     The Framework Agreement is underpinned, on the one hand, by the consideration ‘that contracts of an indefinite duration are,
         and will continue to be, the general form of employment relationship between employers and workers’. (3) However, the Framework Agreement at the same time acknowledges that fixed-term employment contracts ‘are a feature of employment
         in certain sectors, occupations and activities which can suit both employers and workers’. (4)
      
      5.     Clause 1 of the Framework Agreement accordingly defines its purpose as follows:
      ‘The purpose of this framework agreement is to:
      (a)      improve the quality of fixed-term work by ensuring the application of the principle of non-discrimination;
      (b)      establish a framework to prevent abuse arising from the use of successive fixed-term employment contracts or relationships.’
      6.     Clause 5 of the Framework Agreement concerns measures to prevent the abuse of successive fixed-term employment contracts or
         relationships:
      
      ‘1.      To prevent abuse arising from the use of successive fixed-term employment contracts or relationships, Member States, after
         consultation with social partners in accordance with national law, collective agreements or practice, and/or the social partners
         shall, where there are no equivalent legal measures to prevent abuse, introduce in a manner which takes account of the needs
         of specific sectors and/or categories of workers, one or more of the following measures:
      
      (a)      objective reasons justifying the renewal of such contracts or relationships;
      (b)      the maximum total duration of successive fixed-term employment contracts or relationships;
      (c)      the number of renewals of such contracts or relationships.
      2.      Member States after consultation with the social partners and/or the social partners shall, where appropriate, determine under
         what conditions fixed-term employment contracts or relationships:
      
      (a)      shall be regarded as “successive”;
      (b)      shall be deemed to be contracts or relationships of indefinite duration.’
      7.     Finally, the Framework Agreement provides in Clause 8(3):
      ‘Implementation of this agreement shall not constitute valid grounds for reducing the general level of protection afforded
         to workers in the field of the agreement.’
      
      8.     Directive 1999/70 allows Member States to define the terms used in the Framework Agreement but not specifically defined therein
         in conformity with national law or practice provided that the definitions in question respect the content of the Framework
         Agreement. (5) Such a measure is designed to take account of the situation in each Member State and the circumstances of particular sectors
         and occupations, including the activities of a seasonal nature. (6)
      
      9.     Under Article 3 of Directive 1999/70, the directive is to enter into force on the day of its publication in the Official Journal of the European Communities, which is 10 July 1999.
      
      10.   Under the first paragraph of Article 2 of Directive 1999/70, Member States are required to ‘bring into force the laws, regulations
         and administrative provisions necessary to comply with this directive by 10 July 2001’ or to ensure that, by that date at
         the latest, ‘management and labour have introduced the necessary measures by agreement’. If necessary, and following consultation
         with management and labour, Member States may have a maximum of one more year, under the second paragraph of Article 2 of
         the directive, to take account of special difficulties or implementation by a collective agreement. The Commission has explained
         that a year’s extension, as described above, was granted up to 10 July 2002 in the case of Greece.
      
      B –    National law
      11.   The relevant provisions of Greek law are Law No 2190/1994 and the presidential decrees transposing Directive 1999/70.
      Law No 2190/1994
      12.   Article 21 of Law No 2190/1994 (7) provides:
      
      ‘... Public services and legal persons ... may employ staff on fixed-term employment contracts governed by private law in
         order to cope with seasonal or other periodic or temporary needs ...; conversion into a contract of indefinite duration shall
         be invalid ...’.
      
      Presidential Decree No 81/2003
      13.   Presidential Decree No 81/2003, (8) which entered into force on 2 April 2003, lays down ‘provisions concerning workers employed under fixed-term contracts’ and
         originally applied, under Article 2(1) thereof, ‘to workers employed under a fixed-term contract or relationship’. However,
         the scope of that provision was subsequently restricted by Presidential Decree No 180/2004 of 23 August 2004 (9) to employment relationships in the private sector. (10)
      
      14.   Article 5 of Presidential Decree No 81/2003, in its original version, contains the following ‘rules to protect workers and
         to prevent circumvention of the law to their detriment’:
      
      ‘1.      Unlimited renewal of fixed-term employment contracts is permitted if justified by an objective reason.
      (a)      There is an objective reason in particular:
      … if the conclusion of a fixed-term contract is required by a provision of statute or secondary legislation.
      …
      3.      Where the duration of successive fixed-term employment contracts or relationships exceeds two years in total, and no reason
         under paragraph 1 of this article applies, it will be presumed that they are aimed at covering the fixed and permanent needs
         of the undertaking or operation, and they shall consequently be converted into employment contracts or relationships of indefinite
         duration. Where there are more than three renewals of successive employment contracts or relationships, as defined in paragraph 4
         of this article, within the space of two years, and no reasons under paragraph 1 of this article applies, it will be presumed
         that they are aimed at covering the fixed and permanent needs of the undertaking or operation, and the contracts concerned
         shall consequently be converted into employment contracts or relationships of indefinite duration.
      
      It shall fall to the employer in each case to prove otherwise.
      4.      Fixed-term employment contracts or relationships shall be regarded as “successive” if they are concluded between the same
         employer and worker under the same or similar terms of employment and they are not separated by a period of time longer than
         20 working days.
      
      5.      The provisions of this article shall apply to contracts, renewals of contracts or employment relationships entered into or
         effected after this decree has come into force.’
      
      15.   Article 5 of Presidential Decree No 81/2003, cited above, was reformulated by Presidential Decree No 180/2004 and now provides
         inter alia as follows: (11)
      
      ‘1.      Unlimited renewal of fixed-term employment contracts is permitted if justified by an objective reason. There is an objective
         reason in particular:
      
      if the renewal is justified by the form or the type or the activity of the employer or undertaking, or by special reasons
         or needs, provided that those circumstances are apparent, whether directly or indirectly, from the contract concerned; such
         circumstances include the temporary replacement of a worker, the carrying out of transient work, the temporary accumulation
         of work, or circumstances in which the fixed duration is connected with education or training, or where a contract is renewed
         with the aim of facilitating a worker’s transfer to related employment or carrying out a specific piece of work or programme,
         or the renewal is connected with a particular event ... 
      
      3.      Where the duration of successive fixed-term employment contracts or relationships exceeds two years in total, it will be presumed
         that they are aimed at covering the fixed and permanent needs of the undertaking or operation, and they shall consequently
         be converted into employment contracts or relationships of indefinite duration. Where there are more than three renewals of
         successive employment contracts or relationships, as defined in paragraph 4 of this article, within the space of two years,
         it will be presumed that they are aimed at covering the fixed and permanent needs of the undertaking or operation, and the
         contracts concerned shall consequently be converted into employment contracts or relationships of indefinite duration. 
      
      It shall fall to the employer in each case to prove otherwise.
      4.      Fixed-term employment contracts or relationships shall be regarded as “successive” if they are concluded between the same
         employer and worker under the same or similar terms of employment and they are not separated by a period of time longer than
         45 days‚ including non-working days.
      
      In the case of a group of undertakings, the term “the same employer”, for the purposes of the preceding subparagraph, shall
         include undertakings in the group.
      
      5.      The provisions of this article shall apply to contracts, renewals of contracts or employment relationships entered into or
         effected after this decree has come into force.’
      
      Presidential Decree No 164/2004
      16.   Special arrangements for workers employed under fixed-term contracts in the public sector are finally established by Presidential
         Decree No 164/2004, (12) which entered into force on 19 July 2004. Article 2(1) of the decree defines its scope as follows:
      
      ‘The provisions of this decree shall apply to staff in the public sector, as that sector is defined in Article 3 of this decree,
         and to the staff of municipal and communal undertakings who work under a fixed-term employment contract or relationship, or
         under a works contract or other contract or relationship concealing a relationship between employer and employee.’
      
      17.   Article 5 of Presidential Decree No 164/2004 includes the following provisions on the lawfulness of successive public sector
         contracts:
      
      ‘1.      Successive contracts concluded between and performed by the same employer and worker in the same or similar professional activity
         and under the same or similar terms of employment shall be prohibited if the contracts are separated by a period of less than
         three months.
      
      2.      Such contracts may be concluded by way of exception if justified by an objective reason. There is an objective reason if the
         contracts succeeding the original contract are concluded for the purpose of meeting similar special needs which are directly
         and immediately related to the form, the type or the activity of the undertaking.
      
      …
      4.      The number of successive contracts shall not, in any circumstances, be greater than three, subject to the provisions in paragraph
         2 of the following article.’
      
      18.   The transitional provisions contained in Article 11 of Presidential Decree No 164/2004 provide inter alia:
      ‘1.      Successive contracts within the meaning of Article 5(1) of this decree which were concluded before, and are still valid at
         the time of, the entry into force of this decree shall henceforth constitute employment contracts of indefinite duration if
         each of the following conditions is met:
      
      (a)      the total duration of the successive contracts must amount to at least  24 months up to the entry into force of this decree,
         irrespective of the number of contract renewals, or there must be at least three renewals following the original contract,
         for the purposes of Article 5(1) of this decree, with a total duration of employment of at least 18 months over a total period
         of 24 months calculated from the date of the original contract;
      
      (b)      the total period of employment under subparagraph (a) must in fact have been completed with the same body, in the same or
         similar professional activity and under the same or similar terms of employment as specified in the original contract …;
      
      (c)      the contract must relate to activities directly and immediately connected with the body’s fixed and permanent needs as defined
         by the public interest that the body serves;
      
      (d)      the total period of employment for the purposes of the preceding subparagraphs must be completed on a full-time or part-time
         basis and in duties identical or similar to those specified in the original contract.
      
      …
      5.      The provisions of paragraph 1 of this article shall also apply to contracts which expired during the three months immediately
         preceding the entry into force of this decree; such contracts shall be regarded as successive contracts valid up to its entry
         into force. The condition set out in paragraph 1(a) of this article must be met upon expiry of the contract.’
      
      III –  Facts and main proceedings
      19.   The original 18 claimants in the main proceedings, (13) who include Mr Adeneler, were employed by the defendant in the main proceedings, the Greek milk organisation Ellinikos Organismos
         Galaktos (ELOG). ELOG, a legal person governed by private law with its registered office in Thessaloniki, is to be considered
         a part of the public sector in the broader sense, under the relevant Greek legislation. (14) ELOG is responsible for administering milk quotas in Greek territory and, in particular in this case, for ensuring compliance
         with the ceilings applying to Greece.
      
      20.   A number of employment contracts under private law, all of which were valid for fixed terms, were concluded in each case between
         ELOG and the individual claimants in the main proceedings. Both the original employment contracts and the subsequent employment
         contracts were concluded for a fixed term.
      
      21.   The initial employment relationships with some of the claimants were established even before 10 July 2001, the end of the
         ordinary period allowed for transposing Directive 1999/70. ELOG concluded its initial employment contracts with the other
         claimants in any event before 10 July 2002, the end of the extended period allowed for transposition of the directive. All
         the contracts – both the original and the subsequent contracts – were concluded in each case for a period of eight months;
         the interval between contracts varied in each case from 22 days to almost 11 months. The claimants were each invariably re-employed
         in the same area of work (for example, as laboratory technicians, secretaries or veterinary surgeons) in which they had previously
         worked under their original employment contract.
      
      22.   When Presidential Decree No 81/2003 entered into force on 2 April 2003, a fixed-term employment relationship was in place
         with each of the claimants. All of those employment relationships expired between June and the end of August 2003. Since then,
         some claimants have been unemployed whilst others have been temporarily re-employed by ELOG under interim arrangements.
      
      23.   In the main action, the claimants argue that their work covers the defendant’s fixed and permanent needs and that its continued
         conclusion of fixed-term employment contracts with them therefore constituted abusive practice. As to the substance, they
         claim that the court should find that the employment contracts connecting them with ELOG are contracts of indefinite duration.
         That finding constitutes the essential prerequisite underpinning the claimants’ further claims, for instance to re-employment
         and payment of outstanding earnings.
      
      IV –  Reference for a preliminary ruling and proceedings before the Court of Justice
      24.   By judgment of 8 April 2004, rectified by order of 5 July 2004, the Monomeles Protodikio Thessalonikis (15) (hereinafter also ‘the referring court’) referred the following questions to the Court of Justice for a preliminary ruling:
      
      (1)      Must a national court – as far as possible – interpret its domestic law in conformity with a directive which was transposed
         belatedly into national law from (a) the time when the directive entered into force, or (b) the time when the time-limit for
         transposing it into national law passed without transposition being effected, or (c) the time when the national measure implementing
         it entered into force? 
      
      (2)      Does Clause 5(1)(a) of the Framework Agreement on fixed-term work mean that, in addition to reasons connected with the nature,
         type or characteristics of the work performed or other similar reasons, the fact solely and simply that the conclusion of
         a fixed-term contract is required by a provision of statute or secondary legislation may constitute an objective reason for
         continually renewing or concluding successive fixed-term employment contracts? 
      
      (3)      (a)   Is a national provision, specifically, Article 5(4) of Presidential Decree No 81/2003, which lays down that successive contracts
         are contracts concluded between the same employer and worker under the same or similar terms of employment, the contracts
         not being separated by a period of time longer than 20 days, compatible with Clause 5(1) and (2) of the Framework Agreement
         on fixed-term work?
      
      (b)      May Clause 5(1) and (2) of the Framework Agreement on fixed-term work be interpreted as meaning that the employment relationship
         between the worker and his employer is presumed to be of indefinite duration only when the requirement laid down in national
         legislation in Article 5(4) of Presidential Decree No 81/2003 is met?
      
      (4)      Is the prohibition, in Article 21 of Law No 2190/1994, on the conversion of successive fixed-term employment contracts into
         a contract of indefinite duration, where those contracts are said to have been concluded for a fixed term to cover the exceptional
         or seasonal needs of the employer but are aimed at covering its fixed and permanent needs, compatible with the principle of
         effectiveness of Community law and the purpose of Clause 5(1) and (2) in conjunction with Clause 1 of the Framework Agreement
         on fixed-term work?
      
      25.   The claimants in the main proceedings, the Greek Government and the Commission have submitted written and oral observations
         to the Court of Justice; ELOG has only taken part in the hearing.
      
      V –  Assessment
      A –    Admissibility of the questions referred for a preliminary ruling
      26.   In their written observations, the Greek Government and the Commission have each cast doubt on the relevance of the questions
         referred to a decision in the case.
      
      The first question referred: relevant time for the purpose of the legal assessment
      27.   The Commission first casts doubt on the relevance to a decision of the first question referred, which is concerned with establishing
         the time from which the obligation to interpret national law in accordance with a given directive arises. The reason for its
         doubts, it explains, is the fact that the disputed employment contracts of all the claimants in the main proceedings did not expire until after Presidential Decree No 81/2003 had been adopted, that is to say, they expired at a time when the period allowed for Greece
         to transpose the directive had already lapsed and when a provision of national law transposing Directive 1999/70 had been
         adopted. The Commission therefore appears to conclude that earlier dates are of no relevance to the main action and the question
         concerning the obligation to interpret domestic law in accordance with the relevant directive at earlier dates is therefore
         superfluous.
      
      28.   However, according to settled case-law, it is solely for the national court to determine, in the light of the particular circumstances
         of the case, both the need for a preliminary ruling in order to enable it to deliver judgment and the relevance of the questions
         which it submits to the Court. The Court can refuse a request submitted by a national court only where it is quite obvious
         that the ruling sought by that court on the interpretation of Community law bears no relation to the actual facts of the main
         action or its purpose or where the problem is general or hypothetical. (16)
      
      29.   In this case, it is anything but obvious that the matter at issue is the late date to which the Commission refers. The referring court alone can determine the relevant
         date for the purposes of national law for assessing the legality of imposing fixed terms on employment contracts (whether
         it is the date of conclusion of the contract or the date of its expiry) and the legislation that is applicable in that regard
         (whether it is Presidential Decree No 81/2003 or some other provisions of national law). It is by no means inconceivable that
         the national court will conclude in this case that the legality of the fixed-term employment contracts must be assessed in
         each case on the basis of the legal situation prevailing on the dateof their conclusion. That date, as far as we know, in any case precedes the expiry of the period prescribed by Directive 1999/70 for its transposition by Greece, that is to say, it precedes 10 July
         2002.
      
      30.   According to information provided by the claimants in the main proceedings which is not in dispute, both the first and the
         second fixed-term employment contracts ‘in particular’ were concluded, at least with some of the claimants, even before expiry
         of the period allowed for Greece to transpose the directive, that is to say, before the abovementioned date of 10 July 2002. (17) It may therefore be relevant to ascertain, not least in view of those contracts, whether or not the national law applying
         to them was to be interpreted in conformity with the directive and Framework Agreement even before expiry of the period prescribed
         for their transposition.
      
      31.   In those circumstances, the question as to the date from which the obligation to interpret national law in conformity with
         a given directive arises is by no means obviously irrelevant. The doubts raised by the Commission as to the relevance of the first question referred to a decision in the case cannot
         therefore be sustained.
      
      The second and third questions referred: subsequent change of the position under national law 
      32.   By its second and third questions, the referring court seeks essentially to ascertain whether the Framework Agreement can
         be interpreted as not precluding the definitions of objective reasons and succession adopted by the Greek legislature in Presidential
         Decree No 81/2003. In its written and oral observations, the Greek Government comments in this regard that now, in the light
         of the adoption of special provisions applying to the public sector by Presidential Decrees Nos 164/2004 and 180/2004, Presidential
         Decree No 81/2003 can no longer apply to the main action, and consequently that the questions relating to that provision are
         irrelevant to the decision in the main action. The Greek Government thus objects that the second and third questions are irrelevant
         to a decision in the case.
      
      33.   It should first be noted in this regard that Article 234 EC confers jurisdiction on the Court to interpret Community law; therefore, changes in national legislation after the order making the reference cannot influence that interpretation. (18)
      
      34.   Furthermore, according to the case-law cited above, it is solely for the national court to assess the relevance of its reference
         for a preliminary ruling to a decision in the case; (19) the Court of Justice can, at best, reject the questions referred to it if they are obviously immaterial to a decision in
         the case. (20)
      
      35.   Contrary to the Greek Government’s arguments, it is by no means obvious in this case that the claimants in the main proceedings are now all (21) covered by the special provisions governing the public sector newly created by Presidential Decree No 164/2004 and, therefore,
         that the previous legislative situation, involving Presidential Decree No 81/2003 in its 2003 version, is no longer applicable
         to the persons concerned.
      
      36.   The rules laid down in Presidential Decree No 164/2004 do indeed have retroactive effect in so far as they also expressly
         apply to specific employment relationships dating from the two years preceding its entry into force. At the time of its entry
         into force on 19 July 2004, there must, though, still have been a valid employment contract or the last such contract must
         have expired no more than three months previously. (22) According to the referring court, however, the employment contracts of the claimants in the main action all expired long
         before that date, between June and September 2003.
      
      37.   Nor is it obvious that Presidential Decree No 180/2004 restricts the material scope of Presidential Decree No 81/2003, withretroactive effect, to employment relationships in the private sector. Presidential Decree No 180/2004 in any case contains no express provision
         to that effect. What is more, the relevant amending provisions do not appear to have entered into force until August 2004. (23)
      
      38.   Accordingly, it is also clear from the hearing on that point that there is no common ground between the parties over the provisions
         of Greek law applicable at the material time.
      
      39.   In view of those circumstances, it is not in any case obvious that the second and third questions referred bear no relation
         to the actual facts of the main action or its purpose. The reference for a preliminary ruling must therefore be declared admissible
         in that respect.
      
      The fourth question: material scope of the Framework Agreement
      40.   The fourth question referred focuses on the implications under the Framework Agreement of abusing the provisions of Article 21
         of Law No 2190/1994 in concluding fixed-term employment contracts in the public sector. The Greek Government maintains in
         that regard that those provisions fall outside the scope of the Framework Agreement. It explains that the agreement is intended
         to prevent abuses arising from the conclusion of several successive fixed-term employment relationships, whilst Article 21 of Law No 2190/1994 concerns only the first fixed-term employment relationship concluded. Thus, the Greek Government, for its part, questions the relevance of the question
         referred to a decision in the case.
      
      41.   However, contrary to the view expressed by the Greek Government, it is by no means obvious that Article 21 of Law No 2190/1994 cannot in fact have implications – at least indirectly – for the legality of successive fixed-term employment relationships. After all, the provision in question prohibits the renewal or fresh conclusion of fixed-term
         employment relationships only in specific circumstances. It can be inferred conversely from the above that fresh employment
         relationships may be concluded in all other circumstances. Thus, the claimants in the main proceedings have gone unchallenged
         in their argument that, in practice, the public sector has relied for years on Article 21 of Law No 2190/1994 as the basis
         for concluding employment relationships, in each case for an eight-month fixed term and separated by four-month intervals,
         between the same worker and employer. In the light of those circumstances, an interpretation of the Framework Agreement may
         be useful to the referring court and material to a decision in the main action. Consequently, nor are there doubts in this
         regard about the admissibility of the reference for a preliminary ruling.
      
      B –    Time from which the obligation to interpret national law in accordance with a given directive arises (first question)
      42.   By its first question, the referring court seeks to ascertain the time from which it must interpret its national law in accordance
         with the relevant directive. It lists three possible times, not just the date of expiry of the period prescribed for transposition
         or the date of entry into force of the measures (belatedly) transposing the directive concerned into national law, but it
         also expressly refers to the preceding date of entry into force of the directive. The period prior to expiry of the time allowed
         for transposition is indeed relevant for at least some of the claimants in the main action. (24)
      
      43.   It is already established in case-law that national laws, regulations and administrative provisions must be interpreted in
         conformity with the relevant directive. (25) Thus, where national law allows an interpretation in conformity with a directive, for example because the relevant provisions
         contain general clauses or non-specific legal concepts, the national court must exercise fully the ‘discretion’ it is given
         to meet the requirements of Community law. (26)
      
      44.   That obligation arises in any case upon expiry of the period prescribed in a directive for its transposition. (27) The national court is on no account at liberty to wait for the directive actually to be transposed, possibly belatedly, into
         national law. After all, the obligation to give an interpretation in conformity with Community law applies to national law
         as a whole and is not restricted to the laws, regulations or administrative provisions adopted specifically to implement the
         directive. (28) Accordingly, the obligation to interpret national law in conformity with the directive in question exists entirely independently
         of whether and when the directive concerned is actually transposed. (29)
      
      45.   Moreover, I have already pointed out in my Opinion in Wippel, (30) however, that provisions of national law must be interpreted and applied in conformity with directives even before the time-limit for their transposition has expired or, to be more precise, from the date of entry into force of the directive concerned. That view was endorsed most recently
         by Advocate General Tizzano in the Mangold case. (31) The Kolpinghuis Nijmegen judgment (32) is sometimes understood in the same way; (33) it does not in any event rule out the solution proposed here.
      
      46.   The following considerations in particular support the argument that national courts are obliged to interpret domestic law in conformity with directives even before expiry of the period prescribed for their implementation:
      
      47.   It is well known that directives have legal effect immediately upon their entry into force: from that time onwards, they are binding upon Member States as to the result to be achieved (third paragraph of Article 249 EC).
      
      48.   The Court thus concluded, in the light of the principle of Community solidarity laid down in Article 10 EC, that Member States
         must refrain from taking any measures liable seriously to compromise the result prescribed in a directive even during the
         period prescribed for transposition of that directive (prohibition on frustrating the objective of a directive). (34)
      
      49.   However, it is not only that obligation to refrain from taking particular measures, specifically developed by the Court, that can be inferred from the third paragraph of Article 249 EC in conjunction with
         Article 10 EC. In its first paragraph, Article 10 EC also imposes a positive obligation to take all appropriate measures, whether general or particular, that is to say, to do everything necessary, to ensure compliance
         with the requirements of Community law. (35) Where directives require implementation, that obligation under Community law as to the result to be achieved already exists
         upon their entry into force. (36) In that context, the obligation to take all measures necessary to achieve the result prescribed by a directive is binding
         on all the authorities of Member States including, for matters within their jurisdiction, the courts. (37) Accordingly, the objectives of a directive are also binding on the courts of Member States upon its entry into force.
      
      50.   The courts are in fact bound by Community law to the extent that they are even required, according to the Court’s case-law,
         to take into account legally non-binding recommendations. (38)
      
      51.   The fact that the national courts are bound by the result to be achieved by directives certainly does not mean that they would
         be obliged – even before the period prescribed for their transposition has expired – to refrain from applying conflicting national law. (39) That issue does not arise in any case if the law is interpreted in conformity with the directives. For instance, if a court
         interprets its national law in conformity with a directive, the provisions concerned will in fact be applied rather than disapplied. (40)
      
      52.   The fact that Member States are given a period within which to transpose a directive and are therefore not obliged to adopt
         the laws, regulations or administrative provisions necessary for its transposition before the end of that period does not, incidentally, mean that there is no obligation to
         interpret national law in conformity with the directive concerned from its entry into force. (41) The fact that a directive allows the national rule-making bodies a period for its transposition by no means signifies that
         the courts may also avail themselves of that transposition period. On the contrary, the transposition period is introduced
         solely to take account of the technical difficulties involved in the rule-making process, (42) which can arise, for example, in the parliamentary legislative procedure or in negotiations between management and labour.
         This is apparent also in Directive 1999/70 at issue here; the transposition period prescribed in the first paragraph of Article 2
         thereof is indeed confined exclusively to the adoption of the necessary laws, regulations and administrative provisions and to agreements between management and labour, but the date of its entry into force is not, for that matter, deferred in any way. Therefore, the transposition period in
         question makes no difference to the binding nature of the predetermined objectives, even from entry into force of the directive. (43)
      
      53.   Nor is it likely that the national court could anticipate the national rule-making bodies or even contradict them by interpreting
         existing national law in conformity with directives before the end of the period prescribed for their transposition. As already
         mentioned, the result to be achieved by a directive is also binding upon the courts, for matters within their jurisdiction,
         from entry into force of the directive. Thus, if the national court can contribute to achieving the result prescribed by the
         directive, even before the end of the period allowed for its transposition, by interpreting existing law, it is not anticipating the national rule-makers; it is merely applying the law created by them. In so doing, it is carrying
         out its very own function and is at the same time making its contribution towards fulfilling the obligations under Community
         law of the Member State concerned. This, of course, does not affect the national rule-makers’ duty to achieve the result prescribed
         by the directive, if necessary by creating new provisions within a specified period. (44)
      
      54.   The first question referred should therefore be answered as follows:
      A national court is required, immediately upon entry into force of a directive, to interpret the whole body of rules of national
         law, so far as possible, in the light of the wording and purpose of that directive, in order to achieve an outcome consistent
         with the objective pursued by the directive.
      
      C –    Objective reason for imposing a fixed term on employment relationships (second question)
      55.   By its second question, the referring court seeks essentially to ascertain which aspects, for the purposes of the Framework
         Agreement, may constitute objective reasons justifying the conclusion of successive fixed-term employment relationships. It
         specifically asks whether the simple fact that the conclusion of a fixed-term employment contract is prescribed by a legislative provision can constitute an objective reason within the meaning of the Framework Agreement. The excerpt, cited by the referring court,
         from Article 5(1)(a) of Presidential Decree No 81/2003 in its 2003 version contains a provision to that effect.
      
      56.   The concept of objective reasons is not defined in any greater detail in the Framework Agreement, or specifically in Clause 5(1)(a)
         thereof. Consequently, Member States and management and labour enjoy broad discretion to flesh out that concept, paying attention
         to the special features of the individual Member States, sectors and occupations. (45) However, in so doing, they continue to be bound, in accordance with the third paragraph of Article 249 EC, by the results
         to be achieved by the directive and Framework Agreement annexed thereto. In its 17th recital, even Directive 1999/70 itself states that the definitions contained in national law respect the content of the Framework
         Agreement.
      
      57.   The Framework Agreement of course expressly recognises that fixed-term employment contracts are a feature of employment in
         certain sectors, occupations and activities which can suit both employers and workers. (46) Framework Agreement and directive alike do not therefore preclude the adoption of national rules permitting or even expressly
         prescribing – because of the special features of a particular sector such as the public service (47) – the conclusion of fixed-term employment relationships for specific sectors, occupations or activities. In such cases, the
         objective reason for concluding the fixed-term employment contract lies in precisely those special features which are considered
         to be characteristic of employment in the sector, occupational area or activity concerned. (48) Furthermore, an objective reason may lie, for example, in efforts to reintegrate specific categories of persons – such as
         the long-term unemployed or unemployed persons who have exceeded a particular age-limit – into working life.
      
      58.   However, a provision such as the passage of Article 5(1)(a) of Presidential Decree No 81/2003 which is material to this case
         is an entirely non-specific reference provision in that it refers to any national law and any national regulation which prescribe the conclusion of a fixed-term contract. The provision therefore deems there to be an
         objective reason even where a law or regulation provides only in very general terms for the conclusion of fixed-term employment
         relationships without it being clear from the wording, or at least from the spirit and purpose, and the context of the provision
         concerned precisely what the characteristics of the sectors, occupations, activities or persons concerned are that justify
         imposing such fixed terms.
      
      59.   Such a broadly worded, non-specific provision is particularly susceptible to abuse and is consequently inconsistent with the
         objectives of the Framework Agreement. The establishment of objective reasons provided for in that agreement, which may justify
         the use of fixed-term employment contracts, is intended to assist in preventing precisely such abuse of fixed-term employment
         contracts; that purpose is clearly defined specifically in Clause 1(b) of the Framework Agreement and, moreover, is echoed
         particularly clearly in the introductory sentence of Clause 5(1) thereof. (49) However, the more general the provision defining an objective reason, the less likely it is to fulfil that purpose of the
         Framework Agreement and the easier it will be to undermine the model of the contract of indefinite duration as the general
         form of employment relationship. (50)
      
      60.   To summarise, it can therefore be stated that an objective reason within the meaning of Clause 5(1)(a) of the Framework Agreement
         can be considered to exist only if it is clear from the wording, or at least from the spirit and purpose, and the context
         of the provision concerned precisely what the characteristics of the sectors, occupations, activities or persons concerned
         are that justify recourse to fixed-term employment relationships. The mere fact that the conclusion of a fixed-term employment
         relationship is prescribed by a national law, regulation or administrative provision is not sufficient in that respect. 
      
      61.   The referring court’s second question should therefore be answered as follows:
      The mere fact that the conclusion of a fixed-term employment relationship is prescribed by a national law, regulation or administrative
         provision does not constitute an objective reason for the purposes of Clause 5(1)(a) of the Framework Agreement.
      
      D –    Successive fixed-term employment relationships (third question)
      62.   The first part of the third question referred deals with the definition of the concept of successive employment relationships.
         The second part concerns the associated problems of converting fixed-term employment relationships into relationships of indefinite
         duration.
      
      Interpretation of the term ‘successive’ (Question 3(a))
      63.   In the first part of its third question (Question 3(a)), the referring court enquires whether the provisions of Clause 5(1)
         and (2) of the Framework Agreement preclude a national provision such as Article 5(4) of Presidential Decree No 81/2003 in
         its 2003 version which provides that one of the conditions governing the existence of successive employment contracts or relationships
         is that there must be no more than 20 days (51) between the contracts concerned.
      
      64.   The concept of succession is one of the main legal concepts in the Framework Agreement. Of course, the Framework Agreement
         and, by extension, Directive 1999/70 are not intended primarily to obstruct the conclusion of individual fixed-term employment relationships; on the contrary, they are focused above all on the possibilities for pursuing abusive
         practices by concluding such contracts in succession (successive employment relationships), as well as on improving the quality
         of such fixed-term employment relationships. (52) In particular where a number of fixed-term employment relationships have been concluded in succession, there is a danger that the employment relationship of indefinite duration, the employment relationship model defined by
         management and labour, (53) will be circumvented, thus giving rise to the problem of abuse. That is why Clause 5(1) of the Framework Agreement expressly
         requires that measures be introduced to prevent abuse arising from the use of successive fixed-term employment relationships.
      
      65.   However, the Framework Agreement does not itself contain a definition of the term ‘successive’ and instead leaves its detailed
         definition to the Member States. In that context, Clause 5(2)(a) of the Framework Agreement even leaves it to them to decide
         whether actually to proceed at all with a definition in that regard, where it provides that ‘Member States ... shall, where appropriate, determine under what conditions fixed-term employment contracts or relationships ... shall be regarded as “successive”...’. (54) However, if a Member State decides to proceed with such a definition, it does not enjoy complete discretion; on the contrary,
         it is bound by the result to be achieved by the directive and Framework Agreement pursuant to the third paragraph of Article 249 EC,
         as recital 17 in the preamble to Directive 1999/70 also expressly makes clear.
      
      66.   As the Commission rightly points out, Clause 5(2)(a) of the Framework Agreement must therefore be interpreted in the light
         of the objective of the directive, which is actually to prevent abuse. Under Clause 5(1) of the Framework Agreement, Member
         States are not simply requested but are expressly obliged to adopt measures for that purpose.
      
      67.   Defining the concept of succession so restrictively that it cannot even apply to a substantial proportion of the cases of
         successive fixed-term employment relationships and so that the definition chosen is without any effect is incompatible with
         that objective. In so doing, the cases concerned would effectively fall outside the scope of the national measures affording
         protection against abuse of fixed-term employment relationships, and the protection afforded to workers – the objective pursued
         by the directive – could not take effect.
      
      68.   A provision such as Article 5(3) of Presidential Decree No 81/2003 in its 2003 version gives rise to that very concern. If
         only those fixed-term employment relationships that are separated by intervals not exceeding 20 working days are deemed to
         be ‘successive’, it is very easy in that case to circumvent the very protection afforded to workers against abusive practice
         that is the specific aim of the Framework Agreement. Employers need only wait 21 working days in each case before concluding
         a new employment contract with the same worker. The referring court, the Commission and the claimants in the main proceedings
         have rightly raised that issue. They maintain that such a short and inflexible interval between relationships allows employment
         to continue for years, with brief intervals of just 21 working days in each case, such cases consequently falling outside
         the scope of the national provisions protecting against abusive practice. Ultimately, the abuse of fixed-term employment relationships
         is almost encouraged by such practice.
      
      69.   In the light of those considerations, a provision which defines as ‘successive’ only those employment relationships which
         are separated by intervals not exceeding 20 working days is incompatible with the objective of protection pursued by the Framework
         Agreement and with the objective of Directive 1999/70.
      
      70.   I should point out merely in passing that a provision of that kind can also infringe other relevant provisions of Community
         law. After all, a provision which allows employment of indefinite duration subject to an annual interval of 21 working days
         could in effect result in permanent employment relationships comprising unpaid annual leave, in particular in Member States
         or sectors where most of that annual leave generally tends to be taken in a particular month, in August for example. However,
         a practice of that kind would be incompatible with Article 7 of Directive 2003/88/EC of the European Parliament and of the
         Council of 4 November 2003 concerning certain aspects of the organisation of working time. (55) The article in question provides that Member States are to ‘... take the measures necessary to ensure that every worker is
         entitled to paid annual leave of at least four weeks ...’. The Court regards that entitlement of every worker to paid annual
         leave is a particularly important principle of Community social law from which there can be no derogations. (56)
      
      71.   Therefore, to summarise:
      Clause 5(1) in conjunction with Clause 5(2)(a) of the Framework Agreement precludes a provision of national law under which
         one of the conditions governing the existence of successive employment contracts or relationships is that there must be no
         more than 20 working days between the contracts concerned.
      
      Conversion into an employment relationship of indefinite duration (Question 3(b))
      72.   While the first part of the third question, discussed above, concerned the prevention of abuse of successive fixed-term employment relationships, the second part of the question (Question 3(b)) focuses on penalties imposed for any abuse that may arise. The referring court seeks essentially to ascertain whether the Framework Agreement allows a presumption of conversion from
         fixed-term employment relationships into relationships of indefinite duration only where there have been intervals not exceeding
         20 working days between successive employment relationships. That rule is laid down in Article 5(3) in conjunction with Article 5(4)
         of Presidential Decree No 81/2003 in its 2003 version.
      
      73.   In that regard, it must first be stated that the Framework Agreement leaves the imposition of penalties for an abuse of successive
         fixed-term employment relationships to the discretion of the Member States. The only provision in that regard is laid down
         in Clause 5(2)(b) of the Framework Agreement, which refers to conversion into employment relationships of indefinite duration
         by way of example but does not by any means prescribe it as a compulsory measure. It is, after all, only where appropriate that Member States are to determine under what conditions fixed-term employment contracts or relationships are to be deemed
         to be contracts or relationships of indefinite duration.
      
      74.   Consequently, although Member States are obliged under Clause 5(1) of the Framework Agreement to introduce measures actually
         to prevent the abuse of successive fixed-term employment relationships, the agreement does not in fact introduce an obligation to convert such employment relationships into relationships of indefinite duration as a means of penalising abuse; on the contrary, the Framework Agreement provides for such conversion merely as a possibility. (57)
      
      75.   Member States therefore enjoy broad discretion in deciding whether and how they will penalise the abuse of successive fixed-term
         employment relationships. Where a Member State succeeds in preventing such abuse specifically by means of pre-emptive measures,
         for instance by adopting measures which do not allow such cases to arise in the first place, penalties as a whole can quite
         conceivably be superfluous. The only obligation contained in the directive – apart from the obligation to improve the quality
         of fixed-term employment relationships – consists in the objective actually toprevent the abuse of successive fixed-term employment relationships.
      
      76.   Even the nature of and detailed arrangements for any penalties are not specified in the Framework Agreement. The fact that
         the conversion of fixed-term employment relationships into relationships of indefinite duration is specifically referred to
         as a distinct possibility does not rule out other measures, such as the award of compensation to the workers concerned. (58)
      
      77.   If the penalty itself is subject to discretion, Member States have a fortiori free rein to lay down the conditions under which
         a particular penalty is to be imposed. If they decide in favour of converting fixed-term employment relationships into relationships
         of indefinite duration, such conversion does not necessarily have to take place in all circumstances; it can, for example,
         be restricted to particularly blatant cases of abuse.
      
      78.   In the light of those considerations, there are no objections to presuming that an employment relationship exists for an indefinite
         duration only if there have been particularly short intervals not exceeding 20 working days between the individual successive
         fixed-term employment contracts (see, in that regard, Article 5(3) in conjunction with Article 5(4) of Presidential Decree
         No 81/2003 in the 2003 version). Clause 5(2)(b) of the Framework Agreement does not preclude a provision of that kind.
      
      79.   The Framework Agreement therefore lays down requirements of varying stringency as regards measures to prevent abuse and measures to penaliseabuse. The requirements for preventing the abuse of successive fixed-term employment contracts, with which the first part of the
         third question referred (Question 3(a)) was concerned, are more stringent than the requirements relating to the – in any case
         non-compulsory – penalties for such abusive practices, with which the second part of that question (Question 3(b)) is concerned.
         Accordingly, Clause 5 of the Framework Agreement makes it possible to limit the scope of application of the specific penalty
         comprising conversion of fixed-term employment relationships into relationships of indefinite duration to cases where there have been no more than
         20 working days between the individual contracts, and not to presume such conversion in other cases. However, as far as preventing abuse is concerned, the Framework Agreement cannot – as shown above – be interpreted as meaning that an abuse as such actually exists only where there are successive fixed-term
         employment contracts separated by brief intervals not exceeding 20 working days; if that were the case, the objective of protection
         pursued by the Framework Agreement would in many respects become meaningless. (59)
      
      80.   I should mention merely in passing that conversion of fixed-term employment relationships into relationships of indefinite
         duration restricted to certain cases does not constitute an infringement of the prohibition of deterioration, (60) as it is set out in Clause 8(3) of the Framework Agreement. Compared with previous practice in Greece, the situation of workers
         employed for a fixed term in the public sector – rather than deteriorating – ultimately improves, given that Presidential
         Decree No 81/2003 in its original version, or currently Presidential Decree No 164/2004, in any event makes it possible, in
         respect of certain categories of situation, to convert fixed-term employment contracts into contracts of indefinite duration.
      
      81.   The claimants in the main proceedings argue that the earlier legal situation in Greece had indeed made it possible to pursue
         a more liberal practice as regards converting fixed-term employment contracts into contracts of indefinite duration, in which
         regard they cite Article 8(3) of Law No 2112/1920. However, it could not be clarified definitively in the proceedings before
         the Court whether that provision had ever been made use of in the public sector in Greece. The results of the hearings appear
         to suggest that any such instances, if they did arise, would have been isolated cases and not part of usual practice. However,
         the question whether the transposition of Directive 1999/70 leads to a deterioration in the level of protection afforded to
         workers must be assessed by reference to the actual facts and not on the basis of theoretical considerations. The fact that
         Greek law in the light of Directive 1999/70 expressly provides for the possibility of converting fixed-term employment relationships
         into relationships of indefinite duration, even if only in some specific cases, must consequently be regarded as an increase,
         rather than a reduction, in the level of protection afforded to the workers concerned, for the purposes of Clause 8(3) of
         the Framework Agreement.
      
      82.   Thus, to summarise:
      Clause 5(1) in conjunction with Clause 5(2)(b) of the Framework Agreement does not preclude a national provision which provides,
         only in certain cases involving successive fixed-term employment relationships constituting abuse, that those relationships
         are to be deemed to be employment relationships of indefinite duration but makes no such provision in other cases.
      
      E –    Special features in the public sector: prohibition against converting fixed-term employment relationships into relationships
            of indefinite duration (fourth question)
      83.   By its fourth question, the referring court seeks essentially to ascertain whether the provisions of Clause 5(1) and (2) of
         the Framework Agreement preclude a national provision which prohibits, by operation of law, conversion in the public sector
         of fixed-term employment relationships into relationships of indefinite duration, even in cases where the statutory requirements
         governing the use of such fixed-term employment relationships might have been circumvented in an abusive manner.
      
      84.   As I have just mentioned, (61) Clause 5(2)(b) of the Framework Agreement leaves to the discretion of the Member States the decision whether to make any
         provision at all for converting fixed-term employment relationships into relationships of indefinite duration and as to the
         conditions under which that conversion, where appropriate, is to take place. The Framework Agreement certainly does not require
         that every abuse of fixed-term employment contracts be penalised by their conversion into contracts of indefinite duration.
         So, even though the statutory restrictions on recourse to fixed-term employment relationships under private law have, allegedly,
         been circumvented in this case in an abusive manner, (62) the Framework Agreement does not require as a compulsory measure that provision be made for conversion into employment relationships
         of indefinite duration. Accordingly the Framework Agreement itself expressly recognises ‘that their detailed application [that
         is to say, of the agreement’s general principles and minimum requirements relating to fixed-term work] needs to take account
         of the realities of specific national, sectoral and seasonal situations’. (63)
      
      85.   The principles of public service law laid down in national law – not least in the Greek Constitution (64) – in particular play an important part in this case; they are based on the model of the established public servant. The ‘established
         post’ principle applies and access to positions as public servants is regulated by a specific legal procedure. Moreover, strict
         limits are imposed by law in the Greek public sector on recourse to employment relationships under private law – usually only
         for a fixed term – and conversion of such relationships into relationships of indefinite duration is as a rule prohibited.
      
      86.   Such a statutory prohibition against converting fixed-term employment relationships into relationships of indefinite duration,
         which is laid down not least in Article 21 of Law No 2190/1994, can be justified by the objective of preventing circumvention
         of the principles of public service law described above. (65) Accordingly, nor does the Framework Agreement preclude that prohibition, unless it is implemented, for instance, in a discriminatory
         manner or it in some other way infringes the general principles of Community law. However, in the circumstances at issue,
         there is nothing to suggest that this is the case.
      
      87.   Irrespective of that point, the referring court is, of course, still required to interpret the whole body of rules of national
         law in conformity with the directives concerned in order to achieve an outcome in the main proceedings that is, so far as
         possible, consistent with the aims of the directive and Framework Agreement. (66) If the court therefore concludes that the use of fixed-term employment relationships under private law constituted abuse in the cases pending before it, it will have to assess whether its national law makes provision for or, in any event, allows
         in the light of the directive, the imposition of penalties for such abuse other than conversion into employment relationships
         of indefinite duration. For example, the award of compensation to the persons concerned would be a possibility.
      
      88.   On the whole, the fourth question referred should be answered as follows:
      Clause 5(1) in conjunction with Clause 5(2)(b) of the Framework Agreement does not preclude a prohibition in the public sector
         against converting fixed-term employment contracts into contracts of indefinite duration, even in cases where the statutory
         requirements governing the use of such fixed-term employment relationships might have been circumvented in an abusive manner.
      
      VI –  Conclusion
      89.   I therefore propose that the Court of Justice should answer the questions referred by the Monomeles Protodikio Thessalonikis
         as follows:
      
      (1)      A national court is required, immediately upon entry into force of a directive, to interpret the whole body of rules of national
         law, so far as possible, in the light of the wording and purpose of that directive, in order to achieve an outcome consistent
         with the objective pursued by the directive.
      
      (2)      The mere fact that the conclusion of a fixed-term employment relationship is prescribed by a national law, regulation or administrative
         provision does not constitute an objective reason for the purposes of Clause 5(1)(a) of the Annex to Council Directive 1999/70/EC
         of 28 June 1999 concerning the Framework Agreement on fixed-term work concluded by ETUC, UNICE and CEEP.
      
      (3)      (a)   Clause 5(1) in conjunction with Clause 5(2)(a) of the Annex to Directive 1999/70 precludes a provision of national law under
         which one of the conditions governing the existence of successive employment contracts or relationships is that there must
         be no more than 20 working days between the contracts concerned.
      
      (b)      Clause 5(1) in conjunction with Clause 5(2)(b) of the Annex to Directive 1999/70 does not preclude a national provision which
         provides, only in certain cases involving successive fixed-term employment relationships constituting abuse, that those relationships
         are to be deemed to be employment relationships of indefinite duration but makes no such provision in other cases.
      
      (4)      Clause 5(1) in conjunction with Clause 5(2)(b) of the Annex to Directive 1999/70 does not preclude a prohibition in the public
         sector against converting fixed-term employment contracts into contracts of indefinite duration, even in cases where the statutory
         requirements governing the use of such fixed-term employment relationships might have been circumvented in an abusive manner.

         contracts into contracts of indefinite duration. It is also apparent from ELOG’s pleadings at the hearing that the claimants
         in the main proceedings do not all fall within the scope of the transitional provisions of Presidential Decree No 164/2004.

      27 –	This is apparent, for example, from Case C-106/89 Marleasing [1990] ECR I-4135, paragraph 8, and Case C-91/92 Faccini Dori [1994] ECR I-3325, paragraph 26: both judgments were delivered in cases where the period prescribed for transposition of the
         relevant directive had already lapsed without transposition being effected (paragraph 4 of the Marleasing judgment and paragraph 8 of the Faccini Dori judgment). See also, more recently, Case C-456/98 Centrosteel [2000] ECR I-6007, paragraphs 16 and 17.

      29 –	Contrary to what the referring court might be implying, its first question is therefore by no means relevant only if a
         directive ‘was transposed belatedly into national law’ but is relevant generally for all directives, including those which
         are transposed within the time allowed.

         on 10 July 1999.
      
      44 –	According to settled case-law, transposing a directive into national law does not necessarily require its provisions to
         be reproduced verbatim in a specific express legal rule; a general legal context may be sufficient. However, it is essential
         for national law to guarantee that the national authorities will effectively apply the directive in full, that the legal position
         under national law is sufficiently precise and clear and that individuals are made fully aware of their rights and, where
         appropriate, may rely on them before the national courts (see, for example, Case C-168/03 Commission v Spain [2004] ECR I-8227, paragraph 36, Case C-410/03 Commission v Italy [2005] ECR I-0000, paragraph 60, and Case C-456/03 Commission v Italy [2005] ECR I-0000, paragraph 51).

      51 –	Article 5(4) of Presidential Decree No 81/2003 in its 2003 version expressly provides that those 20 days must be working
         days. Since, in its question, the national court refers expressly to that provision, all subsequent references to days will
         be understood to mean working days.
