      VIII –  Summary
      IX –  Conclusion
      I –  Introduction
      1.        The present case is a Treaty infringement action under Article 226 EC whereby the Commission seeks a declaration from the
         Court of Justice that, by reason of the fact that numerous large cities have concluded directly with pension scheme providers
         nominated by collective agreement framework agreements for occupational pension schemes for their employees without a European
         call for tenders, the Federal Republic of Germany had until 31 January 2006 failed to fulfil its obligations under Council
         Directive 92/50/EEC of 18 June 1992 relating to the coordination of procedures for the award of public service contracts (2) and, since 1 February 2006, has failed to fulfil its obligations under Directive 2004/18/EC of the European Parliament and
         of the Council of 31 March 2004 on the coordination of procedures for the award of public works contracts, public supply contracts
         and public service contracts. (3)
      
      2.        The present proceedings are characterised in particular by the Commission’s tactical decision not to focus, by way of example,
         on the contested contract awards of individual cities but to challenge, across the board, the award practice of all cities
         of a particular size. That procedural approach results necessarily in a particular emphasis attaching to evidential questions
         on the burden of proof and the Commission’s duty to substantiate.
      
      3.        The present proceedings raise also numerous legal questions. Without doubt, the most difficult is that concerning the relationship
         between the rights to bargain collectively and to autonomy in collective bargaining, on the one hand, and Directives 92/50
         and 2004/18 which give effect to freedom of establishment and freedom to provide services, on the other. As the alleged infringement
         of the procurement directives can be traced back, ultimately, to criteria established in collective agreements with the cities
         concerned, it may be questioned, in fact, whether the interplay between obligations based on fundamental freedoms, on the
         one hand, and the rights to bargain collectively and to autonomy in collective bargaining, on the other, gives rise to a conflict,
         and, if so, what are the consequences.
      
      4.        As I will propose in this Opinion, the rights to bargain collectively and to autonomy in collective bargaining must be regarded
         as elements of the general principles of Community law and accordingly as fundamental social rights. If in formal terms there
         is a finding of non-compliance with the procurement directives, clarification will thus be needed on how the obligation to
         respect the procurement directives may be reconciled with the fundamental rights to bargain collectively and to autonomy in
         collective bargaining.
      
      II –  Legal framework
      A –    Community law
      1.      Directive 92/50
      5.        According to Article 1(a)(viii) of Directive 92/50, employment contracts do not constitute public service contracts. 
      
      6.        According to Article 8 of Directive 92/50, contracts which have as their object services listed in Annex I A must be awarded
         in accordance with the provisions of Titles III to VI.
      
      7.        Title III of Directive 92/50 concerns the choice of award procedures and the rules governing design contests, Title IV contains
         common rules in the technical field, Title V common advertising rules and Title VI common rules on participation, criteria
         for qualitative selection and criteria for the award of contracts.
      
      8.        Annex I A to Directive 92/50 groups services within the meaning of Article 8 in 16 categories. The sixth category covers ‘financial
         services’, in particular ‘insurance services’ and ‘banking services and securities dealing’. 
      
      2.      Directive 2004/18
      9.        By reason of Article 16(e) of Directive 2004/18, the directive does not apply to public service contracts which concern employment
         contracts.
      
      10.      According to Article 20 of Directive 2004/18, contracts which have as their object services listed in Annex II A must be awarded
         in accordance with Articles 23 to 55. Those articles contain rules on specifications and contract documents (Articles 23 to
         27), on the different award procedures (Articles 28 to 34), on advertising and transparency (Articles 35 to 43) and on the
         conduct of the procedure (Articles 44 to 55). 
      
      11.      Annex II A to Directive 2004/18 groups services in 16 categories. The sixth category covers ‘financial services’, in particular,
         ‘insurance services’ and ‘banking and investment services’.
      
      B –    National law
      1.      Gesetz zur Verbesserung der betrieblichen Altersversorgung (Law on the enhancement of occupational old-age pensions)
      12.      Paragraph 1 of the Gesetz zur Verbesserung der betrieblichen Altersversorgung of 19 December 1974 (4) (‘BetrAVG’) is worded:
      
      ‘Employer’s guarantee concerning an occupational old-age pension
      (1)      If an employee is given by his employer a guarantee of old-age, invalidity or survivor’s pension benefits on grounds of his
         employment relationship (occupational old-age pension), the provisions of this Law shall apply. A scheme for occupational
         old-age pensions may be implemented directly by an employer or through the conduit of one of the pension providers mentioned
         in Paragraph 1b(2) to (4). An employer shall be responsible for ensuring the provision of the benefits he has guaranteed even
         where he does not implement the scheme directly.
      
      (2)      Occupational old-age pension schemes shall also be deemed to exist where:
      …
      3.      future entitlement to earnings is converted into an inchoate right, of equal value, to pension benefits (conversion of earnings),
         or
      
      …’
      13.      Paragraph 1a of the BetrAVG provides as follows:
      
      ‘Right to an occupational old-age pension funded through conversion of earnings
      (1)      An employee shall have the right to demand from his employer that the future earnings to which he is entitled, to a maximum
         of 4% of the relevant ceiling for the assessment of contributions to the statutory pension fund, are paid into an occupational
         old-age pension scheme on the basis of conversion of earnings. The scheme for the implementation of an employee’s right shall
         be determined by agreement. If an employer is willing to allow for implementation through the conduit of a pension fund (Paragraph 1b(3)),
         the occupational old-age pension scheme shall be implemented by that body; otherwise an employee shall have the right to demand
         that his employer concludes a life assurance contract in his favour (Paragraph 1b(2)). …’
      
      14.      Paragraph 17 of the BetrAVG provides:
      
      ‘Personal scope and derogation by way of collective agreement
      …
      (3)       Derogations from the provisions of Paragraphs 1a, 2 to 5, 16, the first sentence of Paragraph 18a, and Paragraphs 27 and 28
         may be effected by collective agreement. 
      
      …
      (5)      To the extent that entitlement to earnings is based on a collective agreement, conversion of earnings may be effected in respect
         of that entitlement only to the extent that a collective agreement provides for or permits such conversion.’
      
      2.      Tarifvertrag zur Entgeltumwandlung für Arbeitnehmer/-innen im kommunalen öffentlichen Dienst (Collective agreement on the
         conversion of earnings for local authority employees)
      
      15.      Paragraph 2 of the Tarifvertrag zur Entgeltumwandlung für Arbeitnehmer/-innen im kommunalen öffentlichen Dienst of 18 February
         2003 (‘TV-EUmw/VKA’) is worded as follows: 
      
      ‘Principle of conversion of earnings
      As a supplement to the collectively agreed rules on occupational old-age pensions (ATV/ATV-K), the present collective agreement
         establishes principles governing the conversion of earnings components determined by collective agreement for the purposes
         of occupational old-age pensions.’ 
      
      16.      Paragraph 5 of the TV-EUmw/VKA provides:
      
      ‘Exercise of the right to conversion of earnings
      (1)      An employee wishing to exercise his right to conversion of earnings shall serve on his employer, in a timely manner, written
         notice to that effect. An employee shall be bound by the agreement with his employer on the conversion of earnings for a period
         of no less than one year. 
      
      …’
      17.      Paragraph 6 of the TV-EUmw/VKA provides:
      
      ‘Implementation methods
      Subject to the second and third sentences of this paragraph, conversion of earnings within the framework of the implementation
         methods provided for by the Gesetz zur Verbesserung der betrieblichen Altersversorgung (Law on the enhancement of occupational
         old-age pensions) shall be implemented with public bodies offering supplementary pension schemes. In the case of occupational
         old-age pension provision referred to in the first sentence, an employer may also adopt implementation methods offered by
         the Sparkassen finance group or local authority insurance companies. Should the need arise, a collective agreement at district
         level may provide for derogations from the first and second sentences of this paragraph.’
      
      III –  Facts
      18.      In the framework of efforts by the Federal Republic of Germany to encourage the development of funded occupational old-age
         pensions for employees, the BetrAVG includes provision for the conversion of earnings. In substance, that principle of conversion
         of earnings means that, at an employee’s request, part of his future salary is used to fund an occupational old-age pension
         through the conversion of future entitlement to earnings into a right, of equal value, to pension benefits.
      
      19.      Although Paragraph 1a of the BetrAVG provides, in general, that employees have a right to an occupational old-age pension
         funded through the conversion of earnings within the limits provided by law, Paragraph 17(5) of the BetrAVG includes an extensive
         derogation from that principle. According to Paragraph 17(5), in relation to earnings which are based on a collective agreement,
         the conversion thereof may be effected only to the extent that a collective agreement provides for or permits such.
      
      20.      In that context, on 18 February 2003, the Vereinigung der kommunalen Arbeitgeberverbände (Federation of Local Authority Employer
         Associations; the ‘VKA’) and the service sector trade union ver.di – Vereinte Dienstleistungsgewerkschaft e.V. concluded the
         TV-EUmw/VKA, granting workers in municipal public sector employment a right to conversion of earnings. At the same time, the
         TV-EUmw/VKA established several features of that scheme for conversion of earnings which derogate from the provisions of the
         BetrAVG. The VKA concluded a collective agreement on the same terms with the civil service trade union dbb Tarifunion.
      
      21.      In contrast to the BetrAVG, the TV-EUmw/VKA expressly identifies the pension scheme providers with which occupational pension
         contributions may be accumulated by way of conversion of earnings. In that regard, Paragraph 6 of the TV-EUmw/VKA provides,
         in particular, that conversion of earnings must be implemented, as a rule, with public bodies offering supplementary pensions.
         However, notwithstanding that general determination, according to Paragraph 6 of the TV-EUmw/VKA, local authority employers
         may decide also to cooperate with the Sparkassen finance group or local authority insurance companies. In addition, Paragraph
         6 of the TV-EUmw/VKA provides expressly for the possibility that collective agreements at district level may adopt derogating
         provisions. 
      
      22.      Taking account of the preliminary selection adopted in the TV-EUmw/VKA in favour of certain pension scheme providers with
         which conversion of earnings must be implemented, in simple terms, that conversion of earnings is effected, as a rule, in
         two steps. In order to facilitate conversion of earnings for individual local authority workers, as a first step, local authority
         employers conclude framework agreements with one or more pension scheme providers nominated by collective agreement. Typically,
         those framework agreements include the conditions on which local authority workers may opt, as a second step, for conversion
         of earnings.
      
      IV –  Pre-litigation procedure
      23.      Having become aware of the TV-EUmw/VKA as a result of a complaint, by letter of 12 October 2005, the Commission informed the
         Federal Republic of Germany that, by reason of the acts of local authorities and local authority undertakings in awarding
         service contracts for the provision of occupational old-age pension schemes directly to the organisations and undertakings
         mentioned in Paragraph 6 of the TV-EUmw/VKA without a European call for tenders, it might have contravened Article 8 in conjunction
         with Titles III to VI of Directive 92/50 and the principles of freedom of establishment and freedom to provide services established
         in Articles 43 EC and 49 EC and, in particular, the prohibition on discrimination inherent in those principles. The Government
         of the Federal Republic of Germany was called upon, in accordance with Article 226 EC, to respond within a period of two months.
      
      24.      By its reply of 29 March 2006, the Federal Republic of Germany indicated that local authority bodies, in their capacity as
         employers, could not be regarded in functional terms, in the context of commitments made by collective agreement, as contracting
         authorities within the meaning of procurement law. In addition, the scheme for conversion of earnings and pension provision
         resulting from collective agreement and individual contracts of employment did not constitute a public contract. Moreover,
         the rules contested by the Commission were protected by the principle of the autonomy of collective bargaining.
      
      25.      By letter of 4 July 2006, the Commission delivered to the Federal Republic of Germany a reasoned opinion in accordance with
         the first paragraph of Article 226 EC. In order to take account of the amendment to Community law which had meanwhile been
         effected and, in particular, to take account of the fact that Directive 2004/18 had entered into force, the Commission supplemented
         its complaint by the allegation that on grounds of the contested conduct the Federal Republic of Germany had infringed, until
         31 January 2006, the abovementioned provisions of Directive 92/50 and, since 1 February 2006, has infringed the corresponding
         provisions of Directive 2004/18. In addition, the Commission adhered to its view that the conduct contravened also the principles
         of freedom of establishment and freedom to provide services established in Articles 43 EC and 49 EC and, in particular, the
         prohibition on discrimination inherent in those principles. 
      
      26.      In reply to the reasoned opinion, by letter of 15 November 2006, the Federal Republic of Germany reasserted its position.
         Moreover, it stressed that the implementing agreements concluded with pension providers could not be viewed in isolation.
         Instead, those agreements constituted part of employment law or, alternatively, were overlaid by such. However, in accordance
         with Article 16(e) of Directive 2004/18, employment contracts were excluded from the scope of that directive. In addition,
         the Federal Republic of Germany annexed a legal opinion written by Professor Koenig and Mr Pfromm in response to the Commission’s
         reasoned opinion in which those authors concluded that in the cases at issue here, having regard to the principle of autonomy
         in collective bargaining, there could be no obligation to invite tenders and that, in any event, neither the personal nor
         the material scope of the procurement directives was triggered. In that context, it was argued also that in individual cases
         the thresholds laid down in those directives were not satisfied.
      
      27.      In order to determine whether in the present case exclusion of the procurement rules was objectively justified and reasonable
         in order to attain the social policy objectives linked to the conversion of earnings, the Commission then sent to the Federal
         Republic of Germany a set of questions. As, in the Commission’s view, the reply of the Federal Republic of Germany of 1 March
         2007 was unconvincing, it moved to commence proceedings.
      
      V –  Procedure before the Court and forms of order sought by the parties
      28.      In its application, which was received at the Registry of the Court on 24 June 2008, the Commission claims that the Court
         should: 
      
      –        declare that by reason of the fact that local authorities and local authority undertakings with more than 1 218 employees
         awarded public service contracts concerning occupational pension schemes without a European call for tenders directly to the
         organisations and undertakings mentioned in Paragraph 6 of the TV-EUmw/VKA, the Federal Republic of Germany had, until 31 January
         2006, infringed Article 8 in conjunction with Titles III to VI of Directive 92/50 and, since 1 February 2006, has infringed
         Article 20 in conjunction with Articles 23 to 55 of Directive 2004/18; 
      
      –        order the Federal Republic of Germany to pay the costs.
      29.      In its defence received on 16 September 2008, the Federal Republic of Germany contends that the Court should:
      
      –        dismiss the action; 
      –        order the Commission to pay the costs.
      30.      In its reply received on 27 October 2008, the Commission narrowed the scope of its action. In that regard, it contended, in
         particular, that the Court should declare that by reason of the fact that local authorities and local authority undertakings
         which had, in 2004 and 2005, more than 2 044 employees, in 2006 and 2007, more than 1 827 employees and, for awards since
         2008, more than 1 783 employees, awarded public service contracts concerning occupational pension schemes without a European
         call for tenders directly to the organisations and undertakings mentioned in Paragraph 6 of the TV-EUmw/VKA, the Federal Republic
         of Germany had, until 31 January 2006, infringed Article 8 in conjunction with Titles III to VI of Directive 92/50 and, since
         1 February 2006, has infringed Article 20 in conjunction with Articles 23 to 55 of Directive 2004/18.
      
      31.      In its rejoinder of 12 December 2008, the Federal Republic of Germany repeated its contention that the Court should dismiss
         the action.
      
      32.      By order of the President of the Court of 5 December 2008, the Kingdom of Denmark and the Kingdom of Sweden were granted leave
         to intervene in support of the forms of order sought by the Federal Republic of Germany. They submitted written observations
         on 14 and 15 April 2009 to which the Commission responded with observations received on 30 June 2009.
      
      33.      At the hearing on 12 January 2010, the representatives of the Commission, the Federal Republic of Germany, the Kingdom of
         Denmark and the Kingdom of Sweden presented their oral arguments.
      
      VI –  Main arguments of the parties
      34.      Essentially, the Commission contests the compatibility with Directives 92/50 and 2004/18 of the preliminary selection made
         in Paragraph 6 of the TV-EUmw/VKA in favour of certain pension scheme providers. In the Commission’s view, that provision
         of the collective agreement restricts local authority employers, in contravention of the directives, in their choice of pension
         scheme providers with which to implement conversion of earnings. Accordingly, to the extent that the relevant thresholds are
         satisfied, the award of an individual contract results necessarily in an infringement of those procurement directives.
      
      35.      In that regard, the Commission starts from the premiss that Directives 92/50 and 2004/18 apply to the framework agreements
         which local authority employers conclude with the selected pension scheme providers. More specifically, according to the Commission,
         those framework agreements must be categorised as public service contracts within the meaning of Directives 92/50 and 2004/18,
         whose value, in the case of numerous German cities, exceeds the relevant thresholds. Therefore, on awarding such public service
         contracts, the provisions of those directives must be observed. 
      
      36.      In the Commission’s view, such assessment is not precluded by the fact that the preliminary selection in favour of certain
         pension scheme providers was established by collective agreement resulting from negotiations between the VKA and the trade
         unions. Community law, so it argues, does not accord any general privilege to the autonomy of collective bargaining. Moreover,
         the obligation to call for tenders does not depend on the characteristics of the individual employment relationships of local
         authority workers.
      
      37.      The German Government contests the Commission’s action primarily with the argument that Community procurement law does not
         apply to a case such as the present. In its view, what is decisive is the fact that the selection procedure challenged by
         the Commission was adopted by the social partners and, accordingly, must be evaluated in the light of the principle of autonomy
         in collective bargaining. From that standpoint, it follows that the preliminary selection by collective agreement in favour
         of certain pension scheme providers contested in the present case and the implementation of such in the individual framework
         agreements, in fact, falls outside the scope of the procurement directives. To that extent, the German Government favours
         a corresponding application of the principles established in Albany (5) and Van der Woude. (6) Moreover, application of the procurement directives places public sector employers and their employees at a considerable
         disadvantage in comparison with private sector employers and their employees as this deprives the former group of the possibility
         to select pension scheme providers by way of collective agreement.
      
      38.      In relation to the facts, the German Government emphasises in that connection how collective agreements constitute the basis
         for and shape the right to conversion of earnings for workers in municipal public sector employment. In that regard, it stresses
         in particular that under the first sentence of Paragraph 1a(1) of the BetrAVG employees have a statutory right to the conversion
         of such earnings as are not based on a collective agreement. In that connection, in implementing the conversion of earnings,
         following a request by an employee, the choice of the pension scheme provider is, in principle, a matter for the employer.
         However, in relation to earnings which are based on a collective agreement, under Paragraph 17(5) of the BetrAVG, conversion
         may be effected only if, and, to the extent that, collective agreement provides for or permits such conversion. As the TV-EUmw/VKA
         provides for such possibility, in the view of the German Government, the scheme for the conversion of earnings at issue here
         is based entirely on collective agreement. 
      
      39.      Moreover, it points out that the parties to the collective agreement took advantage of the possibility provided for in Paragraph 17(3)
         of the BetrAVG to derogate from various provisions of that law. In those circumstances, the preliminary selection – challenged
         by the Commission – in favour of certain pension scheme providers with which conversion of earnings must be implemented constitutes
         a restriction on the freedom of choice available to employers under Paragraph 1a(1) of the BetrAVG. Thus, employers are deprived
         of their authority to select and this is replaced by a consensual solution arrived at by the social partners. In that regard,
         selection of the pension scheme providers, in itself, reflects employee concerns. 
      
      40.      Even if, in principle, the procurement directives apply to a case such as the present, in the view of the German Government,
         the framework agreements challenged by the Commission necessarily fall outside the material scope of Directives 92/50 and
         2004/18. 
      
      41.      Having regard to the fact that on the basis of a collective agreement local authority employers have been deprived of the
         authority to select pension scheme providers, according to the German Government, it would run contrary to the system to categorise
         those employers as contracting authorities within the meaning of the procurement directives. Moreover, so it argues the framework
         agreements concluded by local authority employers with pension scheme providers do not of themselves establish insurance relationships;
         instead, they establish simply the conditions on which employees may establish individual insurance contracts with pension
         scheme providers. In addition, employers generally conclude several such framework agreements with different pension scheme
         providers. Moreover, in its view, those framework agreements are not for pecuniary interest, the exclusion established in
         Article 16(e) of Directive 2004/18 applies to the framework agreements and in calculating the value of the individual agreements
         the Commission relied on incorrect presumptions.
      
      42.      The Kingdom of Denmark and the Kingdom of Sweden support Germany’s contention that the action for failure to fulfil Treaty
         obligations should be dismissed. 
      
      43.      The Kingdom of Denmark considers in particular the Danish system of occupational old-age pensions to be at risk if the Court
         were to conclude that agreements of a certain size concluded between public employers and trade unions concerning the investment
         of funds earmarked for the pensions of public sector employees must be subject to a compulsory call for tenders. 
      
      44.      In their legal observations, both the Kingdom of Denmark and the Kingdom of Sweden stress the relevance of the abovementioned
         judgments in Albany and Van der Woude. In their view, even if, in principle, the procurement directives must be presumed to apply in situations such as those at
         issue here, account must be taken of the fact that the rules governing occupational old-age pensions derive directly from
         collective agreements. Moreover, all that has been agreed is which pension scheme provider should manage the pension savings.
         The funds, however, belong to employees alone and, as a result, no question arises of a contract for the provision of services
         to public sector employers. Moreover, Article 16(e) of Directive 2004/18 applies, according to which the directive does not
         apply to employment contracts.
      
      VII –  Legal appraisal
      A –    Applicability of Directives 92/50 and 2004/18 to collectively agreed framework agreements
      45.      The first question of principle which has to be answered in the present proceedings is whether the procurement directives
         may apply to collectively agreed framework agreements. 
      
      46.      In that connection, there is considerable dispute on whether the framework agreements in question may fall within the primary
         law provisions on freedom of establishment and freedom to provide services.
      
      47.      As Directives 92/50 and 2004/18 were adopted on the basis of powers included in the title of the EC Treaty on freedom of establishment
         and freedom to provide services, if those fundamental freedoms are not applicable to the framework agreements in question,
         on an interpretation of the procurement directives in conformity with primary law, it follows that those framework agreements
         necessarily are excluded also from the scope of the procurement directives. 
      
      48.      The pleas advanced to counter the application of the fundamental freedoms to the framework agreements in question can be summarised
         in three lines of argument.
      
      49.      The first line of argument starts from the presumption that collective agreements – and, correspondingly, also framework agreements
         established by collective agreement – are excluded from the scope of competition rules under primary law. That exception in
         the field of competition law – according to such argument – can be applied in relation to fundamental freedoms and, as a result,
         collectively agreed framework agreements are excluded from the scope of fundamental freedoms. 
      
      50.      A second line of argument, which, although not advanced systematically by the German Government, can be recognised as the
         underlying motive in some of its arguments, starts from the principle that fundamental freedoms do not apply to horizontal
         relations. In that connection, it may be queried in particular whether, having regard to the participation of worker representatives
         in collectively agreed accords, application of fundamental freedoms to collectively agreed framework agreements conflicts
         with the principle that fundamental freedoms do not apply to horizontal relations.
      
      51.      A third line of argument, advanced in the alternative, starts from the categorisation of the principle of autonomy in collective
         bargaining as a fundamental social right and the relationship between fundamental rights and fundamental freedoms. In that
         context, the argument is advanced in particular that collectively agreed framework agreements enjoy fundamental rights protection
         and, as a result, the substance of those agreements can no longer be measured against fundamental freedoms.
      
      52.      I will consider those three lines of argument in the following section. 
      
      1.      Whether or not collective agreements are excluded from the scope of primary law competition rules and, if so, the applicability
         of such an exclusion to the fundamental freedoms
      
      53.      This first line of argument presumes, in my view, incorrectly, that, in principle, collectively agreed rules do not fall within
         the scope of primary law competition rules and that the exclusions from the scope of competition rules under primary law apply
         without more to the fundamental freedoms. Thus, that line of argument cannot be accepted.
      
       (a)   No exclusion from primary law competition rules for collective agreements
      54.      In three landmark judgments delivered on the same day in Albany, (7)Brentjens’ (8) and Drijvende Bokken, (9) the Court ruled on the applicability of primary law competition rules to collective agreements and collectively agreed schemes.
         
      
      55.      Those cases concerned the compatibility of a national system of occupational pensions with the competition rules under primary
         law. The central question was whether the introduction of compulsory affiliation – at the request of employer and worker representatives
         in a given sector – to an occupational pension scheme for all undertakings in that sector could constitute an infringement
         of Article 10 EC in conjunction with Article 81 EC or an infringement of Article 86(1) EC in conjunction with Article 82 EC.
         In that connection, it was necessary to clarify whether, if at all, and, if so, under what conditions, a collective agreement
         between employers and workers in a given sector introducing a sectoral occupational pension scheme could fall within the scope
         of Article 81(1) EC. 
      
      56.      In order to clarify the relationship between the competition rules of the EC Treaty and the collectively agreed scheme, the
         Court referred, first, to the objectives of a policy in the social sphere and social protection provided for in Article 2
         EC and Article 3(1)(j) EC (10) and, in that connection, stressed that both the right of association and collective bargaining have been given express consideration
         in primary law and in the agreement on social policy. (11)
      
      57.      The Court then stated that certain restrictions of competition are inherent in collective agreements between organisations
         representing employers and workers. However, the social policy objectives pursued by such agreements would be seriously undermined
         if management and labour were subject to Article 81(1) EC when seeking jointly to adopt measures to improve conditions of
         work and employment. (12) As a consequence of those considerations, the Court concluded that, from an interpretation of the provisions of the Treaty
         as a whole which is both effective and consistent, it follows that agreements concluded in the context of collective negotiations
         between management and labour in pursuit of such objectives must, by virtue of their nature and purpose, be regarded as falling
         outside the scope of Article 81(1) EC. (13)
      
      58.      Accordingly, in those judgments, the Court held that collective agreements – and, thus, also collectively agreed schemes and
         decisions – are excluded from the scope of Article 81 EC on satisfying a dual condition; that is, the agreement must (1) have
         been concluded in the framework of collective negotiations (14) and (2) with a view to improving conditions of work and employment. (15)
      
      59.      As the non-applicability of the competition rules in relation to collectively agreed accords does not follow automatically,
         but must be determined in an individual case, the Court did not recognise in those judgments any exclusion from the competition
         rules under primary law for collective agreements. Instead, having regard to the primary law consideration given to collective
         agreements in the field of employment law and, accordingly, in the framework of an interpretation taking account of the Treaty’s
         scheme, the Court held Article 81 EC to be subject to an inherent limitation in relation to collective agreements with a given
         purpose. (16)
      
      60.      Such assessment is not precluded by the fact that both in Albany, Brentjens’ and Drijvende Bokken and in the later case of Van der Woude (17) the Court examined only cursorily whether the collective agreements were concluded with a view to improving conditions of
         work and employment. Naturally, to eliminate all suspicion of abuse of the freedom granted to the social partners in the area
         of competition law, a more rigorous analysis on the substance of the collectively agreed provisions in question would have
         been advisable in those cases, too. (18) None the less, in the framework of an overall assessment of the scheme of those judgments, the conclusion remains that only
         collective agreements with a given purpose were excluded from the scope of Article 81(1) EC. (19)
      
      61.      Against that background, Advocate General Fennelly was correct, in my view, to observe in his Opinion in Van der Woude that, as an exclusion from the general field of application of Article 81 EC, the scope of the ‘Albany exclusion’ must be narrowly construed. Consequently, collective agreements which appreciably affect competition may always
         be challenged on the basis that the agreement does not pursue a genuine social objective because the restrictions resulting
         from it, or from its application, go beyond what is required by the pursuit of its objective. (20) Naturally, that necessarily presupposes a substantive examination of the criterion of whether the collective agreements concerned
         or the individual provisions of such were, in fact, concluded with a view to improving conditions of work and employment.
      
      62.      In the light of the foregoing, I conclude that in Albany, Brentjens’ and Drijvende Bokken the Court did not establish a general exception from the competition rules under primary law for collective agreements. Instead,
         those judgments must be interpreted as determining that Article 81 EC is subject to an inherent primary law limitation in
         relation to collective agreements with a given purpose.
      
       (b)   No general concordance between the scope of the primary law on competition and that of freedom of establishment and freedom
         to provide services
      
      63.      In its argument, the Federal Republic of Germany presupposes that the limitations and exceptions established in competition
         law apply, as a rule, to the fundamental freedoms. Against that background, it contends in particular that the Court should
         apply to the present case per analogiam – and, accordingly, without any assessment taking account of the particular features of freedom of establishment and freedom
         to provide services – the reasoning and principles of Albany, Brentjens’ and Drijvende Bokken.
      
      64.      In my opinion, that view put forward by the German Government cannot be accepted. 
      
      65.      Although both the rules within the field of freedom of establishment and freedom to provides services and the rules in the
         field of freedom of competition take account of the objective of completing the internal market, the fact that an agreement
         or activity is excluded from the scope of the competition rules does not necessarily mean that it is excluded also from the
         scope of the rules on freedom of movement. (21)
      
      66.      In consistent case-law, the Court has held that although an agreement or an activity may be included within the scope of the
         provisions on free movement at the same time it may fall outside the scope of the provisions on competition and vice versa. (22)
      
      67.      Therefore, according to the case-law of the Court, there is no mandatory concordance between the scope of the competition
         rules under primary law and that of the fundamental freedoms. The fact that collectively agreed rules aimed at improving the
         conditions of work and employment, in accordance with Albany, Brentjens’ and Drijvende Bokken, do not fall within the scope of Article 81 EC, thus, does not imply necessarily that such collectively agreed rules are
         excluded also from the scope of freedom of establishment and freedom to provide services.
      
      68.      Simply in the alternative, I wish to add that, even if the relationship between the principle of autonomy in collective bargaining
         and the fundamental freedoms must be structured similarly to the relationship between the principle of autonomy in collective
         bargaining and competition law as established by primary law, this would not imply that the requirements laid down in Albany, Brentjens’ and Drijvende Bokken could be applied without more to the present case. Instead, giving due regard to the recognition of the principle of autonomy
         in collective bargaining as a fundamental right, (23) the criteria and reasoning set out in those judgments in relation to competition law would need to be evaluated. (24)
      
      2.      The limited horizontal effects of fundamental freedoms
      69.      Nor is the applicability of freedom to provide services and freedom of establishment in the field of collective bargaining
         precluded by the argument – conceivable in the present case – that fundamental freedoms do not apply to horizontal relations.
         
      
      70.      According to that line of argument, the framework agreements in question result, ultimately, from a collective agreement negotiated
         between public sector employers and worker representatives. Taking account of the fact that the principles of freedom to provide
         services and freedom of establishment do not apply to horizontal relations, the participation of workers in the conclusion
         of the collective agreements precludes, in principle, so it is argued, the application of provisions concerning those fundamental
         freedoms to collective agreements and implementing agreements subordinated thereto.
      
      71.      That line of argument must be countered, first, by stating that the TV-EUmw/VKA was concluded between the VKA and trade unions.
         Given the fact that local authority employers, that is, public bodies subject to the requirements of the fundamental freedoms
         participated in the conclusion of the collective agreement, one could describe the effects produced by the fundamental freedoms,
         here, as having, at the most, an indirectly horizontal character to the disadvantage of the trade unions also participating
         in the collective bargaining process.
      
      72.      In addition, in that connection, regard must be had to the settled case-law of the Court, according to which Articles 39 EC,
         43 EC and 49 EC do not apply only to the actions of public authorities but extend also to rules of any other nature aimed
         at regulating in a collective manner gainful employment, self-employment and the provision of services. (25)
      
      73.      That inclusion of collective rules on employment within the scope of the fundamental freedoms is justified by the fact that
         working conditions in the different Member States are governed sometimes by provisions laid down by law or regulation and
         sometimes by collective agreements and other acts concluded or adopted by private persons. Exclusion of collective rules on
         employment from the scope of the fundamental freedoms would carry with it the risk that application of obligations based on
         one of the fundamental freedoms established under primary law would result in inequalities. (26)
      
      74.      In the light of those considerations, I conclude that no arguments can be derived from the principle by which fundamental
         freedoms do not apply to horizontal relations which preclude the application of provisions on freedom of establishment and
         freedom to provide services to collectively agreed framework agreements. 
      
      3.      Categorisation of the rights to bargain collectively and to autonomy in collective bargaining as fundamental social rights
         and their relationship to fundamental freedoms
      
      75.      Nor am I persuaded by the argument that because the fundamental right to autonomy in collective bargaining serves as the basis
         for the specification of the conditions of employment of local authority workers in the TV-EUmw/VKA the substance of such
         collective agreement and its subordinate agreements falls outside the scope of freedom of establishment and freedom to provide
         services. 
      
      76.      It is settled case-law that fundamental rights form an integral part of the general principles of law the observance of which
         the Court ensures. (27) In determining those fundamental rights, the Court draws inspiration from the constitutional traditions common to the Member
         States and from the guidelines supplied by international instruments for the protection of fundamental rights on which the
         Member States have collaborated or to which they are signatories.
      
      77.      The right to bargain collectively is recognised both by various international instruments which the Member States have signed
         or cooperated in – such as the European Social Charter signed in Turin on 18 October 1961, (28) to which, moreover, express reference is made in Article 136 EC – and by instruments developed by those Member States at
         Community level or in the context of the European Union, such as the Community Charter of the Fundamental Social Rights of
         Workers adopted at the meeting of the European Council held in Strasbourg on 9 December 1989, (29) which is also referred to in Article 136 EC, and the Charter of Fundamental Rights of the European Union proclaimed in Nice
         on 7 December 2000. (30)
      
      78.      Against that background, it is beyond question that the right to bargain collectively and the autonomy, accorded to the parties
         to that process, inherent in that right must be recognised also in the Community legal order as fundamental rights which form
         an integral part of the general principles of Community law. (31)
      
      79.      Moreover, by the Treaty of Lisbon – not relevant, ratione temporis, in the present case – the primary law enshrinement of the right to bargain collectively was strengthened by the fact that
         Article 6 TEU declares the Charter of Fundamental Rights of the European Union to have binding legal force. By that general
         reference to the charter, the right to bargain collectively, described in Article 28 of that charter, is now expressly incorporated
         in primary law. (32)
      
      80.      However, the fact that the right to bargain collectively and of the parties to autonomy in that connection are recognised
         as fundamental rights does not permit the conclusion, without more, that the substance of the collective agreements, made
         in exercise of those fundamental rights, and the agreements subordinate thereto automatically fall outside the scope of the
         fundamental freedoms.
      
      81.      In the case of a conflict between a fundamental right and a fundamental freedom, both legal positions must be presumed to
         have equal status. That general equality in status implies, first, that, in the interests of fundamental rights, fundamental
         freedoms may be restricted. However, second, it implies also that the exercise of fundamental freedoms may justify a restriction
         on fundamental rights. (33)
      
      82.      Consequently, categorisation of the rights to bargain collectively and to autonomy in collective bargaining as fundamental
         rights does not result in the automatic or complete exclusion from the scope of the provisions on freedom of establishment
         and freedom to provide services either for the collective agreements concluded in the exercise of those rights or for the
         subordinate agreements concluded in the implementation thereof.
      
      83.      From that, it inexorably follows that the argument according to which both collective agreements, negotiated through the exercise
         of the fundamental right to bargain collectively and the fundamental right to autonomy in such a process, and subordinate
         agreements thereto, eo ipso, fall outside the scope of freedom of establishment and freedom to provide services and secondary law based thereupon is
         unpersuasive. 
      
      84.      Instead, if a conflict between such fundamental freedoms and fundamental rights is established, it must be determined whether,
         having regard to all the circumstances of the case, fundamental freedoms may justify a restriction on the fundamental right
         to bargain collectively and the fundamental right to autonomy in that process or, conversely, whether those fundamental rights
         demand that the scope of those fundamental freedoms and the secondary law based thereupon must be limited. 
      
      4.      Interim conclusion
      85.      In the light of my observations above, I conclude that, in principle, collectively agreed framework agreements fall within
         the scope of freedom of establishment and freedom to provide services. Thus, in principle, the framework agreements in question
         fall also within the scope of procurement directives based on those fundamental freedoms, naturally, subject always to the
         proviso that the conditions for applying such directives are satisfied. 
      
      86.      If it is established that Directive 92/50 or Directive 2004/18 has been contravened as a result of a collectively agreed framework
         agreement, regard must be had, however, to the special status of the rights to bargain collectively and to autonomy in collective
         bargaining as fundamental social rights. In that regard, it must be determined in the circumstances of the individual case
         whether that non-observance of the procurement directives results from exercising the fundamental social rights to bargain
         collectively and to autonomy in collective bargaining, and, if so, whether restricting the exercise of such fundamental social
         rights as a result of obligations established by the procurement directives may be regarded as justified having regard to
         the fundamental freedoms.
      
      87.      In the light of those considerations, in the following analysis I will examine, first, whether the collectively agreed framework
         agreements at issue are compatible with Directives 92/50 and 2004/18. Thereafter, I will examine how a conflict between obligations
         resulting from the procurement directives and the freedom to exercise the fundamental right to bargain collectively and the
         fundamental right to autonomy in collective bargaining may be resolved.
      
      B –    Compatibility of the framework agreements at issue with Directives 92/50 and 2004/18
      88.      The Commission alleges an infringement of Directive 92/50 and of Directive 2004/18 said to result from the fact that numerous
         local authorities and local authority undertakings awarded service contracts concerning occupational pension schemes for their
         employees without a European call for tenders directly to the bodies and undertakings mentioned in Paragraph 6 of the TV-EUmw/VKA.
      
      89.      For the purposes of Directives 92/50 and 2004/18, public service contracts are contracts for pecuniary interest concluded
         in writing between a contracting authority and an economic operator and having as their principal object the provision of
         services.
      
      90.      In the present case, the parties disagree, in particular, on whether, in implementing the preliminary selection established
         by collective agreement, local authorities acted as contracting authorities within the meaning of the procurement directives.
         In addition, there is disagreement on whether the agreements concluded between local authorities and pension scheme providers
         may be classified as contracts for pecuniary interest which have as their object the provision of services and which exceed
         the relevant thresholds.
      
      91.      I will examine both of those main issues in the following analysis.
      
      1.      Categorisation of the cities as contracting authorities
      92.      The Federal Republic of Germany rejects the categorisation of the cities concerned as contracting authorities for the purposes
         of the procurement directives with the argument that in selecting pension scheme providers those cities merely implement the
         requirements of the collective agreement and, hence, do not take an ‘independent’ decision. In addition, so they argue, the
         element of procurement to the benefit of public authorities is absent because in terms of its legal consequences and economic
         effects the conversion of earnings must be classified as pertaining to the employee sphere.
      
      93.      By that argument, the Federal Republic of Germany calls, in essence, for a functional interpretation of the concept of a public
         authority with the objective – as a result of a restrictive interpretation of that element – of narrowing the scope of the
         procurement directives in cases such as the present. That argument cannot be accepted.
      
      94.      At the outset, it must be recalled that the Community rules on public procurement were adopted in pursuance of the establishment
         of the internal market, in which freedom of movement is ensured and restrictions on competition are eliminated. (34) In that connection, the Court has identified that the widest possible opening-up to competition in all Member States for
         public procurement constitutes one of the primary objectives of the procurement directives. (35)
      
      95.      Although it is correct to assert that in consistent case-law the Court has held that the concept of a contracting authority
         must be interpreted not in formal but in functional terms, (36) it must be stressed in that context that such case-law testifies to the efforts of the Court to break up closed national
         procurement markets and – in accordance with the objectives stated in the recitals in the preambles to the procurement directives
         – to open them to the common market. (37)
      
      96.      Accordingly, by its functional interpretation of the concept of a contracting authority, the objective pursued by the Court
         is to ensure the effective attainment of freedom of establishment and freedom to provide services in the field of public contracts.
         To that end, the Court has broadly interpreted the material scope of the procurement directives, and, in that regard, for
         the purposes of classifying a national body (in functional terms) as a contracting authority for the purposes of the procurement
         rules it is irrelevant whether under relevant national rules that characteristic is linked to certain institutional features. (38)
      
      97.      Consequently, case-law on the ‘functional’ notion of a contracting authority facilitates the general purpose of the procurement
         directives, that is, in coordinating the procedures for awarding public contracts, to eliminate barriers to the freedom to
         provide services and goods and, as a result, also to protect the interests of traders established in a Member State who wish
         to offer goods or services to contracting authorities established in another Member State. (39) In so doing, both the risk of preference being given to national tenderers or applicants whenever a contract is awarded by
         the contracting authorities and the possibility that a body financed or controlled by the State, regional or local authorities
         or other bodies governed by public law may choose to be guided by considerations other than economic ones may be avoided. (40)
      
      98.      Although the functional interpretation of the concept of a contracting authority in those terms results, on the whole, in
         an extension of the material scope of the procurement directives, in exceptional cases it may result also in the non-applicability
         of those directives to contracts notwithstanding the fact that in formal terms these were awarded by a contracting authority
         and the remaining requirements for the application of the procurement directives also appear to be fulfilled.
      
      99.      A clear example of this is to be found in Mannesmann Anlagenbau Austria in which the Court held that a contract awarded by a contracting authority, which in principle falls within the scope of
         the procurement directives, ceases to be regarded as a public contract if it is established that, from the outset, the whole
         of the project at issue fell within the objects of an undertaking not subject to procurement law and the works contracts relating
         to that project were entered into by the contracting authority on behalf of that undertaking. (41)
      
      100. The criterion for the non-applicability of the procurement rules applied in Mannesmann Anlagenbau Austria implies, therefore, that the award decision demonstrably must be taken by a private awarding body acting on its own behalf
         and on condition that it bears the entire cost. Given that in such a configuration, although in formal terms the contracting
         authority awards the contract, but neither took nor influenced the decisions on which that contract is based, that precludes
         the risk that in awarding the contract such contracting authority gives preference to national tenderers or applicants or
         is guided by considerations other than economic ones. (42)
      
      101. In the light of the considerations above, I am unpersuaded by the argument advanced by the Federal Republic of Germany, namely
         that in their selection of pension scheme providers local authorities merely implement the requirements of the collective
         agreement and, accordingly, do not act as contracting authorities.
      
      102. First, it must be observed that the collective agreement was concluded between the VKA and the trade unions. In that process,
         as the umbrella association for local authorities and local authority undertakings in Germany, the VKA represented the interests
         of local authority employers for collective bargaining and employment relations purposes. That implies necessarily that local
         authority employers participated, at least, indirectly, in establishing the negotiating positions for which, subsequently,
         in the framework of collective bargaining with the trade unions, the VKA sought to find acceptance and which contributed,
         ultimately, to the basis for the collectively bargained consensus. Against that background, local authority employers could
         influence, at least, indirectly, the preliminary selection in favour of certain pension scheme providers agreed in the TV-EUmw/VKA.
         
      
      103. In the light of the fact that local authority employers could influence, at least, indirectly, the negotiations on the collective
         agreement and, thus, also the outcomes achieved in the TV-EUmw/VKA, their categorisation as contracting authorities for the
         purposes of the procurement directives cannot be questioned by pointing to the requirements and obligations established by
         the collective agreement.
      
      104. Nor is the argument convincing that in the present case, from a functional point of view, local authorities may not be regarded
         as contracting authorities for the purposes of the procurement directives because in terms of its legal consequences and economic
         effects the conversion of earnings must be classified as pertaining to the employee sphere. 
      
      105. Even if it is correct that local authority employers make no contributions whatsoever to occupational pension savings accumulated
         through conversion of earnings, such finding would not of itself suffice to remove the contracts made between local authority
         employers and pension scheme providers from the scope of the procurement directives.
      
      106. Admittedly, the risk of preference being given by contracting authorities to national firms and bidders may be diminished
         when conclusion of the contract by the contracting authority constitutes the outcome of negotiations between the public sector
         employer and one or more workers and only those workers bear the economic consequences of the conclusion of the contract.
         In such a case, workers have, as a rule, a particular interest in ensuring that the most economically advantageous outcome
         is achieved. Regardless of the question whether that factor alone eliminates the risk that the outcome of the negotiations
         gives preference to national firms, for the purposes of assessing the present case it suffices to observe that the negotiations
         on the collective agreement were conducted on the workers’ side by trade unions. Although those trade unions represent the
         workers and, thus, may act as a counterweight to the natural tendency of contracting authorities to favour national firms, (43) trade unions do not bear in a personal sense the financial consequences of the conversion of earnings requested by local
         authority workers. Simply for that reason, the fact that trade unions participated in the negotiations resulting in the conclusion
         of the TV-EUmw/VKA is insufficient to place the selection decisions – predetermined by collective agreement – taken by contracting
         authorities outside the scope of the procurement directives. 
      
      107. In the light of those considerations, I conclude that the local authorities which in implementation of the TV-EUmw/VKA concluded
         contracts with one or more of the pension scheme providers mentioned therein acted as contracting authorities for the purposes
         of the procurement directives.
      
      2.      Categorisation of the framework agreements as contracts for pecuniary interest within the scope of the procurement directives
      
       (a)   Observations on the duty to substantiate and the burden of proof 
      108. By means of a multiplicity of arguments, the German Government contests the categorisation of the framework agreements concluded
         between local authorities and pension scheme providers as contracts for pecuniary interest within the scope of the procurement
         directives. In that regard, it stresses in particular that the framework agreements establish merely the conditions on which
         workers may subsequently conclude individual insurance contracts with pension scheme providers. In that connection, the German
         Government emphasises also that consideration is provided not by local authorities but by employees. In its view, in the absence
         of an economic exchange between pension scheme providers and local authorities the framework agreement is not for pecuniary
         interest. And even if there were to be pecuniary interest, the Commission has not adduced proof that the thresholds are satisfied.
         In addition, so it argues, the exception for employment contracts provided for in Article 16(e) of Directive 2004/18 extends
         to the framework agreements in question. 
      
      109. In the present proceedings, analysis and assessment of those arguments is considerably hampered by the fact that very little
         specific information on the actual framework agreements concluded by individual local authorities has been produced to the
         Court. Particularly problematic, in that respect, is the approach taken by the Commission in relation to evidential matters.
         In wording its action, the Commission limited itself to a generalised challenge, on the basis of statistical information,
         to the award practice of all German cities of a certain size. 
      
      110. None of the framework agreements concluded by those cities were attached to the application. Instead, the Commission limited
         its evidence to the production of some general information sheets, information to members and specimen application forms issued
         by various pension scheme providers. 
      
      111. Against that background, in the present proceedings it remains unresolved, inter alia, on what date each of the framework
         agreements at issue was concluded. Accordingly, it is uncertain whether those framework agreements must be assessed in the
         light of Directive 92/50 or, instead, in the light of Directive 2004/18. The determining factor is always the legal position
         at the time when the operations with procurement law relevance took place. (44) As in the absence of detailed information on the conclusion of the framework agreements in question that time cannot be determined,
         in the present proceedings, a finding that the procurement rules have been infringed may be reached only where conduct would
         constitute an infringement both of Directive 92/50 and Directive 2004/18.
      
      112. In that regard, according to settled case-law it falls to the Commission to prove, in fact, the alleged failure to fulfil
         Treaty obligations. It is the Commission’s responsibility to place before the Court the information needed to enable the Court
         to establish that the obligation has not been fulfilled. In so doing, the Commission may not rely on any presumptions. (45)
      
      113. Against that background, it is for the Commission to produce sufficient evidence to discern an infringement. When that has
         been done, it is incumbent on the Member State to contest substantively and in detail the information produced and the consequences
         thereof. (46)
      
      114. In the light of those considerations, in the following analysis, I will examine the Commission’s argument and the counterarguments
         advanced by the German Government.
      
       (b)   Applicability of Directives 92/50 and 2004/18 to framework agreements 
      115. Although not one single framework agreement at issue between a city and a pension scheme provider has been produced, the German
         Government and the Commission agree on the fact that such framework agreements have been concluded by German cities. However,
         the German Government argues that the conclusion of those agreements cannot be regarded as the award of public contracts because
         the contractual relationship relevant for the purposes of the procurement rules is established only in the framework of an
         individual employee’s participation in conversion of earnings.
      
      116. By this argument, the German Government emphasises the two-step construction of the conversion of earnings procedure. That
         procedure is particularly characterised by the fact that, as a first step, local authority employers conclude framework agreements
         with one or more pension scheme providers selected in accordance with Paragraph 6 of the TV-EUmw/VKA. Such framework agreements
         typically include the conditions on which, as a second step, local authority employees may opt for conversion of earnings.
      
      117. To the extent that the material and personal conditions for application are satisfied, both under Directive 92/50 and under
         Directive 2004/18 framework agreements constitute contracts which are subject to a compulsory call for tenders. 
      
      118. Directive 92/50 does not govern expressly the conclusion of framework agreements. However, it must be observed that in Commission v Greece (47) the Court confirmed the applicability of Council Directive 77/62/EEC of 21 December 1976 coordinating procedures for the
         award of public supply contracts (48) to framework agreements. In the light of that judgment, it must be presumed that, in principle, framework agreements fall
         also within the scope of Directive 92/50. Directive 2004/18 expressly provides for and governs the conclusion of framework
         agreements in Article 32.
      
      119. Although framework agreements fall, in principle, within the scope of the procurement directives, both the Court in Commission v Greece (49) and the legislature in formulating that principle in Directive 2004/18 focused primarily on framework agreements which include
         the terms for subsequent contracts between the contracting authority and the economic operators concerned. (50) However, the present proceedings concern framework agreements establishing the terms for the subsequent conversion of earnings
         by employees of the contracting authorities.
      
      120. Thus, it may be questioned whether Directives 92/50 and 2004/18 must be interpreted as meaning that they include also the
         framework agreements at issue, although in substance these establish terms for insurance contracts which may be entered into
         by local authority employees.
      
      121. In my view, in the specific context of the present proceedings, that question must be answered in the affirmative. 
      
      122. The crucial element in that regard is the fact that the conversion of earnings procedure is structured such that the framework
         agreements establish not only the terms for any conversion of earnings by local authority employees but determine also the
         organisations with which local authority employees may implement conversion of earnings.
      
      123. As I have already stated, the free movement of goods and services and the widest possible opening-up to competition in all
         Member States constitute the primary objectives of Community legislation on public procurement. (51) In that connection, both the risk of preference being given to national tenderers or applicants whenever a contract is awarded
         by the contracting authorities and the possibility that a body financed or controlled by the State, regional or local authorities
         or other bodies governed by public law may choose to be guided by considerations other than economic ones may be avoided. (52)
      
      124. In the light of those objectives, in analysing the framework agreements in question for procurement law purposes, the crucial
         factor is that in concluding a framework agreement a local authority employer determines with which pension scheme provider
         its employees may, as a second step, implement the conversion of earnings. Accordingly, the selection – relevant for procurement
         law purposes – of one or more economic operators is effected on the conclusion of the framework agreement between the local
         authority employer and the pension scheme provider concerned. 
      
      125. Against that background, I conclude that the risk of preference being given to national tenderers or applicants clearly arises
         on conclusion of the framework agreements at issue. Because local authority employees are bound by decisions of local authority
         employers taken in favour of a pension scheme provider, they are limited to electing whether to establish an insurance relationship on the basis of the framework agreement and may not determine with whom. That latter decision was taken by local authority employers on the conclusion of the framework agreement and, as a result,
         in the specific context of the present proceedings, those framework agreements, too, must be included within the scope of
         Directives 92/50 and 2004/18. 
      
      126. As a final argument contesting the applicability of Directive 2004/18 to the framework agreements at issue, the Federal Republic
         of Germany contends, in the alternative, that the limitation on the term of framework agreements subject to a compulsory call
         for tenders to a maximum of four years, provided for in Article 32(2) of that directive, is inappropriate for the creation
         of collective insurance schemes. However, that objection must be rejected as unfounded simply by reason of the fact that under
         that provision that maximum term of four years does not apply if such term is incompatible with the object of the framework
         agreement. 
      
       (c)   Whether the framework agreements are for pecuniary interest
      127. According to the German Government, conversion of earnings is funded, ultimately, by employees alone. Against that background,
         it argues that the framework agreements are not for pecuniary interest within the meaning of Directives 92/50 and 2004/18.
      
      128. Regardless of how, in the context of occupational pensions funded by conversion of earnings, in practical terms, the transfer
         of contributions or premiums is effected, it is certain that by such scheme, ultimately, an employee’s future earnings are
         used for the purposes of his occupational pension. Thus, from an economic point of view, employees, and not contracting authorities,
         bear the costs of occupational pensions. (53) Therefore, from the perspective of procurement law, a scheme of third-party funding must be presumed, in which not the contracting
         authority but the local authority employee concerned confers an economic benefit on the pension scheme provider and, in return,
         acquires to the same value entitlements to future pension.
      
      129. In my view, the fact that the monetary benefit, ultimately, is conferred not by contracting authorities but by local authority
         employees does not conclusively preclude the categorisation of the framework agreements concluded by contracting authorities
         as being for pecuniary interest.
      
      130. The purpose of requiring a pecuniary interest is to ensure that those arrangements which do not concern economic activities
         such as, for example, charitable provision are excluded from the scope of the procurement directives. (54) If, on the other hand, it is clear that an arrangement has an inherent economic purpose, Community procurement law, in principle,
         applies.
      
      131. In that connection, the Court has already clarified that for the purposes of categorisation as a public contract within the
         meaning of the procurement directives it is irrelevant whether the contracting authority uses public resources to pay the
         contractor. (55)
      
      132. In addition, in Carbotermo and Consorzio Alisei, in identifying the conditions under which an in-house award falls outside the scope of Community procurement law, the Court
         emphasised that in determining whether an undertaking’s activities are devoted primarily to a contracting authority it is
         irrelevant who pays the undertaking in question, whether it be that authority or third parties. (56) If, according to that line of case-law, payments by third parties can be relevant in determining the applicability of a derogation
         from procurement law, that must apply a fortiori in determining the applicability of procurement law itself. (57)
      
      133. In the light of the above considerations, I conclude that the benefit conferred by local authority employees in the framework
         of the conversion of earnings suffices to classify the framework agreements concluded by contracting authorities with the
         pension scheme providers concerned as being for pecuniary interest within the meaning of the procurement directives. (58) Consequently, it is unnecessary for contracting authorities to constitute, in economic terms, the ultimate supplier of the
         pecuniary consideration. 
      
       (d)   Non-applicability of the exclusion for employment contracts
      134. According to Article 1(a)(viii) of Directive 92/50, employment contracts do not constitute public service contracts. Article
         16(e) of Directive 2004/18 provides, similarly, that that directive does not apply to public service contracts which concern
         employment contracts. 
      
      135. In the view of the German Government, those exclusions extend to the framework agreements in question. It contends that the
         framework agreements are based on employment relationships with the consequence that their object concerns to that extent
         employment contracts. 
      
      136. I am unpersuaded by that argument.
      
      137. By Article 1(a)(viii) of Directive 92/50 and Article 16(e) of Directive 2004/18, the legislature has stated that provision
         of services may fall within Community procurement law only where this is effected on the basis of contracts. If, on the other
         hand, services are provided in fulfilment of an employment contract, these are not intended to be covered by procurement law. (59)
      
      138. That explicit exclusion of employment contracts from the scope of the procurement directives can be explained by the fact
         that conclusion of an employment contract establishes a considerably more narrow legal relationship than the conclusion of
         a contract for the general provision of services. Against that background, employers should not be precluded by the procurement
         rules from taking account of subjective matters and impressions when taking hiring decisions. (60)
      
      139. Although there is no single definition of the concept of a worker – nor, consequently, of an employment contract – in Community
         law, with that definition varying according to the area in which it is to be applied, (61) in my view, the consistent case-law of the Court defining the concept of a worker for the purposes of Article 39 EC may serve
         as the basis for the definition of an employment contract for the purposes of Directives 92/50 and 2004/18. (62) According to that case-law, a relationship governed by a contract of employment may be considered to exist only where a person
         undertakes, for a certain period of time, to perform services for and under the direction of another person in return for
         which he receives remuneration. (63)
      
      140. Against that background, an agreement between an awarding body and a service provider may be categorised as an employment
         contract for the purposes of Directives 92/50 and 2004/18 only if the service provider undertakes, for a certain period of
         time, to perform services for and under the direction of an awarding body in return for which it receives remuneration. 
      
      141. It is beyond dispute that such a situation does not apply in the case of the framework agreements in question. Thus, in the
         present proceedings, it is immediately apparent that the exclusion for employment contracts established in Article 1(a)(viii)
         of Directive 92/50 and Article 16(e) of Directive 2004/18 does not apply. 
      
       (e)   Thresholds under Directives 92/50 and 2004/18 
      
       (i)   Determination of the relevant thresholds
      142. Both Directive 92/50 and Directive 2004/18 apply only to public service contracts the estimated value of which net of value
         added tax (VAT) is in excess of certain thresholds established in those directives. 
      
      143. As those thresholds are regularly revised, first of all, it must be clarified which threshold was relevant in relation to
         the framework agreements in question. For those purposes, the threshold must be established which applied at the time of the
         contractual negotiations. (64)
      
      144. The case-file does not include any information on the dates at which the individual local authority employers commenced negotiations
         with the relevant pension scheme providers or the dates on which framework agreements were concluded. Having regard to the
         fact that the TV-EUmw/VKA has been in force since 1 January 2003 and, thus, starting from the first half of 2003 negotiations
         could be held with a view to concluding framework agreements in accordance with that collective agreement, (65) for the purposes of the present proceedings, all the thresholds which applied from 1 January 2003 to 4 September 2006 (the
         date on which the period for compliance with the reasoned opinion expired) must be considered relevant. These are: 
      
      (1)      the threshold according to Article 7(1)(a) of Directive 92/50, as amended by European Parliament and Council Directive 97/52/EC
         of 13 October 1997 amending Directives 92/50/EEC, 93/36/EEC and 93/37/EEC concerning the coordination of procedures for the
         award of public service contracts, public supply contracts and public works contracts respectively: (66)the equivalent value in ecus of 200 000 SDR;
      
      (2)      the threshold according to Article 7(b) of Directive 2004/18: EUR 249 000;
      
      (3)      the threshold according to Article 7(b) of Directive 2004/18, as amended by Commission Regulation (EC) No 1874/2004 of 28
         October 2004 amending Directives 2004/17/EC and 2004/18/EC of the European Parliament and of the Council in respect of their
         application thresholds for the procedures for the award of contracts: (67)EUR 236 000;
      
      (4)      the threshold according to Article 7(b) of Directive 2004/18, as amended by Commission Regulation (EC) No 2083/2005 of 19 December
         2005 amending Directives 2004/17/EC and 2004/18/EC of the European Parliament and of the Council in respect of their application
         thresholds for the procedures for the award of contracts: (68)EUR 211 000.
      
      145. In its application, the Commission attempted to circumvent the problem of determining the relevant thresholds by referring
         to the date on which the period of two months for compliance with the reasoned opinion expired. As the reasoned opinion was
         received by the Federal Republic of Germany on 4 July 2006, on the Commission’s argument, the threshold in force on 4 September
         2006 of EUR 211 000 applied. (69)
      
      146. That approach taken by the Commission is not supported by the procurement directives and ignores the essence of procurement
         law. Consequently, such approach cannot be followed. (70) Instead, in determining the applicable threshold, in a case such as the present, reference must be had to the date of the
         contractual negotiations. (71)
      
      147. As in the present case that date cannot be determined, in assessing whether the framework agreements in question satisfy the
         relevant thresholds, the highest threshold applicable in the period at issue must be presumed. That is EUR 249 000.
      
       (ii) Absence of proof that the framework agreements exceed the relevant threshold
      148. The framework agreements at issue are characterised by the fact that at the time of the negotiations leading to their conclusion
         it was impossible to ascertain how many local authority employees would opt, ultimately, for conversion of earnings and, in
         the event of such option, the conditions under which conversion would be effected. Against that background, the procurement
         directives provide that the value of such framework agreements must be determined on the basis of an estimate of the expected
         contract value at the date of the contractual negotiations. (72)
      
      149. In relation to public service contracts without a fixed term or with a term greater than 48 months for which a total price
         is not indicated, Article 9(8)(b) of Directive 2004/18 provides, in addition, for a restriction on the period to be taken
         into account for the purposes of calculating the total price. According to that provision, in the case of such contracts total
         value is to be calculated by multiplying the monthly value by 48. Such a restriction, limiting the calculation period to four
         years, is included also in Article 7(5) of Directive 92/50 which may apply also to framework agreements. (73)
      
      150. Even if, according to the procurement directives, in relation to a framework agreement for which a total price is not indicated,
         the total value to be taken into account must be determined, in principle, thus, on the basis of an ex ante estimate, in the present proceedings the Commission has based its calculations primarily on statistics concerning the participation
         of local authority employees in the conversion of earnings in 2006. Having regard to the fact that the Federal Republic of
         Germany has not put forward any real alternative to that ex post method of calculation, it must be presumed that the readiness of public service employees to take advantage of the option
         for conversion of earnings in 2006 corresponded to the estimates. Accordingly, the participation by public service employees
         in the conversion of earnings system in 2006 constitutes a legitimate starting point for determining whether or not the framework
         agreements in question satisfy the threshold.
      
      151. According to consistent case-law, it is for the Commission to prove the allegation that the Treaty obligation has not been
         fulfilled. Having regard to the observations I made above, in the present infringement proceedings it is incumbent on the
         Commission, therefore, to prove that on the basis of the information available concerning the conversion of earnings in 2006
         it may be presumed that the value of each of the framework agreements in question exceeded the threshold of EUR 249 000.
      
      152. In my opinion, in the present case, the Commission has failed to adduce that proof.
      
      153. In determining which local authority employers have concluded with pension scheme providers framework agreements exceeding
         the threshold relevant for procurement law purposes the Commission relies on a series of statistical data which it combines
         with a set of presumptions. 
      
      154. In its application, the Commission presumed that every large German city concluded for an unlimited term a framework agreement
         with a pension scheme provider. Moreover, according to research by TNS Infratest, (74) attached as an annex to the application, it followed that in December 2006 2.3% of employees in the public service sector
         made use of the facility for the conversion of earnings and that in 2006 the monthly amount converted was approximately EUR
         158 per month. 
      
      155. The Commission then used that statistical information as the basis on which to calculate, in accordance with Article 9(8)
         of Directive 2004/18, the value of each insurance contract entered into by a local authority employee within the scope of
         a framework agreement concluded by his employer as follows: EUR 158 x 48 months = EUR 7 584. According to the Commission,
         it follows from that calculation that every framework agreement which results in the conclusion of 28 or more individual insurance
         contracts has a value of EUR 212 352 or greater and, accordingly, exceeds the threshold – considered by the Commission as
         decisive – of EUR 211 000.
      
      156. In order to determine in which cities no less than 28 local authority employees had applied or were likely to apply for conversion
         of earnings, the Commission combined the abovementioned rate of participation of local authority employees in the conversion
         of earnings procedure of 2.3% with a further academic study in this case on the relationship between the population figures
         for cities and municipalities and the number of local authority workers. (75) The Commission derived from the latter study in particular the fact that in 2000/01 for every 1 000 inhabitants there were
         17.8 local authority workers. According to the Commission, from that figure, for 2006, an employee figure of 16 local authority
         workers for every 1 000 inhabitants can be deduced. From that, in turn, according to its argument, it can be extrapolated
         for 2006/07 that every German city whose population exceeds 76 125 inhabitants concluded a framework agreement in excess of
         the threshold – considered by the Commission as decisive – of EUR 211 000.
      
      157. To identify the cities which are alleged, in fact, to have infringed the procurement directives, the Commission produced a
         list of the largest cities in Germany together with their population figures and, in that regard, showed in its application
         that the 110 largest cities have populations in excess of 76 125 inhabitants and, consequently, concluded the framework agreements
         in question in contravention of procurement law.
      
      158. After the Federal Republic of Germany in its defence – setting out detailed information in substantiation – rejected as incorrect
         the rate of participation of local authority employees in the conversion of earnings procedure of 2.3%, the mean conversion
         amount of EUR 158 per month, the employment figure of 16 local authority workers for every 1 000 inhabitants, the assumption
         that local authority employers conclude a framework agreement with only one pension scheme provider and the assumption that
         every large German city falls within the scope of the TV-EUmw/VKA, the Commission made minor revisions to its calculations.
      
      159. On the basis of a legal opinion of 25 November 2005, (76) in its reply, the Commission now stated the mean amount converted as EUR 106.77 per month and reduced the mean employment
         figure from 16 to 15 local authority workers for every 1 000 inhabitants. In addition, the Commission removed the city of
         Berlin from its calculations. However, it adhered to the estimated rate of participation of local authority employees in the
         conversion of earnings procedure of 2.3% and rejected as inconsequential the argument that individual local authority employers
         had concluded framework agreements with several pension scheme providers.
      
      160. On the basis of those new parameters, according to the Commission, it can be extrapolated that German cities with a population
         in 2004/05 in excess of 136 267 inhabitants, in 2006/07 in excess of 121 800 inhabitants and in 2008/09 in excess of 118 867
         inhabitants concluded framework agreements which exceeded the threshold applicable for the period concerned.
      
      161. To identify the cities which are alleged, in fact, to have infringed the procurement directives, the Commission again referred
         to a list of the largest German cities, now excluding Berlin. Consequently, according to that argument, for 2004/05 the smallest
         city in population terms exceeding the threshold was Darmstadt with a population of 141 257 inhabitants. For 2006/07, it was
         Ingolstadt with a population of 122 167 inhabitants and for 2008/09 Bottrop with a population of 118 975 inhabitants.
      
      162. In its rejoinder, the German Government in reply to that recalculation again stressed the fact that numerous employers concluded
         framework agreements with several pension scheme providers. Moreover, it argued that the mean employment figure advanced by
         the Commission of 15 local authority workers for every 1 000 inhabitants is not meaningful in the present proceedings as that
         employment figure includes also local authority civil servants who, in fact, fall outside the scope of the TV-EUmw/VKA. Only
         85.6% of local authority workers constitute employees who can participate in the conversion of earnings and, as a result,
         so it argued, the statistically relevant mean employment figure is at the most 12.84 local authority workers for every 1 000
         inhabitants. In addition, Germany again contested the estimated rate of participation of local authority employees in the
         conversion of earnings procedure of 2.3% and the estimated monthly amount converted of EUR 106.77 and submitted on the basis
         of the latest information that the mean proportion of local authority employees who took part in conversion of earnings in
         2006 was 2.04% with a mean monthly contribution to conversion of earnings of EUR 89.92. (77)
      
      163. On the basis of that information included in the rejoinder, following the method of calculation adopted by the Commission,
         it may be extrapolated that German cities with a population in excess of 217 610 may have concluded framework agreements with
         an estimated value in excess of EUR 249 000. Consequently, on the basis of a list of the largest German cities it may be concluded
         – in accordance with the argument pursued by the Commission – that in concluding framework agreements on the conversion of
         earnings 33 cities (78) may have contravened Directives 92/50 and 2004/18.
      
      164. That conclusion presupposes, however, that those 33 cities each concluded only one framework agreement with a pension scheme
         provider. However, precisely that assumption was contested by the German Government in the pre-litigation procedure and in
         the subsequent proceedings, too, it remains contested.
      
      165. The resulting uncertainty is of particular significance in the present case. Neither Directive 92/50 nor Directive 2004/18
         precludes contracting authorities from splitting their procurement requirements for services. Such splitting may be regarded
         as contrary to the directives only where this is effected with the intention of avoiding their application. (79) Consequently, what is prohibited is an artificial split of a single contract. Although the Court is decidedly strict in its
         examination of that prohibition, (80) such intention to circumvent cannot be presumed without more. Each individual case in which a contract was split for the
         purposes of an award must be examined according to its context and specificities and, in that regard, particular attention
         must be given to whether there are good reasons pointing in favour of or, on the contrary, against the split in question.
      
      166. In that connection, it is evident from the case-file that in a set of questions of 30 January 2007 addressed to the German
         Government (81) the Commission itself stated that, as a result of earlier answers given by the Federal Republic of Germany, it deduced that
         local authority employers concluded public contracts with different groups of insurers. Against that background, in its set
         of questions the Commission inquired, inter alia, whether between an employer and service provider, generally speaking, framework
         agreements covering all employees or, instead, individual contracts for each employee were concluded. In addition, it requested
         information on whether there were employers which had concluded contracts with several different service providers.
      
      167. In its reply of 1 March 2007, the Federal Republic of Germany clarified that there are different approaches to the implementation
         of conversion of earnings; there are cases in which individual contracts are concluded in respect of each worker and also
         the conclusion of framework agreements between an employer and one or more provider. In that regard, according to the Federal
         Republic of Germany, an employer is not obliged by reason of the collective agreement to opt for one of the three implementation
         methods. It may offer its employees different implementation methods. In practice, according to the Federal Republic of Germany,
         it is not uncommon for employers to conclude framework contracts with several different providers. (82)
      
      168. Notwithstanding that clear answer that the arrangements for the conversion of earnings by local authority employers can differ
         considerably, without further questioning, the Commission commenced proceedings. In the framework of the judicial proceedings,
         it has subsequently remained unresolved whether and, if so, which German cities have concluded framework agreements with several
         pension scheme providers. Also unresolved has remained the question whether, taking account of the specific circumstances
         applying to the case of each city and its employees, good substantive reasons pointed in favour of, or, on the contrary, against
         the conclusion of several framework agreements with different pension scheme providers.
      
      169. In determining whether the Federal Republic of Germany is proven to have infringed the directives, ultimately, in the present
         proceedings, the decisive issue is which party is responsible for the uncertainty whether, and, if so, the grounds on which,
         the largest cities in Germany with the exception of Berlin concluded framework agreements with several pension scheme providers.
         If that uncertainty must be attributed to the defective adduction of evidence on the part of the Commission, it has failed
         to satisfy the burden of proof imposed on it and the action must be dismissed as insufficiently substantiated. However, if
         that uncertainty must be attributed to a failure to cooperate by the Federal Republic of Germany in the proper investigation
         of the facts, the action must be held to be sufficiently substantiated and, consequently, also well founded. 
      
      170. Having regard to the particular circumstances of the case, in my view, that uncertainty must be attributed to a defective
         adduction of evidence on the part of the Commission. 
      
      171. In that regard, I wish to stress that by its action the Commission originally sought a declaration that by reason of the fact
         that the 110 largest German cities have concluded directly with the bodies and undertakings mentioned in Paragraph 6 of the
         TV-EUmw/VKA framework agreements on conversion of earnings, the Federal Republic of Germany has failed to fulfil its obligations
         under Directives 92/50 and 2004/18. Already in the pre-litigation procedure the Federal Republic of Germany countered that
         argument by stating that it was common practice for cities and municipalities to conclude framework agreements with several
         pension scheme providers and that, therefore, it was necessary to differentiate in the calculation whether the thresholds
         were satisfied. However, the Commission ignored such statement and, without requesting the Federal Republic of Germany to
         provide further clarification, commenced proceedings.
      
      172. Having regard to the complexity of the present proceedings raising a multiplicity of legal and factual questions, the Federal
         Republic of Germany cannot be criticised for the fact that neither in the pre-litigation procedure nor in the judicial proceedings
         has it provided of its own accord a summary of all the framework agreements concluded by Germany’s largest cities and explained
         the background thereto. Having regard to the multiplicity of unresolved legal and factual questions which characterise the
         present proceedings in which the Commission questioned the award practice of over 100 German cities throughout the Bundesländer, in the pre-litigation procedure the German Government was obliged, first, to highlight in general terms the factual omissions
         in the Commission’s account. In my view, the Commission should have taken those observations of the German Government as grounds
         for resolving the factual omissions by way of detailed questions. Instead, the Commission commenced proceedings prematurely
         and, as a result, in the judicial phase the German Government considered itself obliged, first, on a factual level to contradict
         in substance the statistical data of the Commission. Here, too, I cannot discern any grounds why the Federal Republic of Germany
         should be blamed for the fact that the Court has not been provided with any explanation whether, and, if so, on what grounds,
         the cities in question concluded framework agreements with several pension scheme providers. 
      
      173. In summary, it must be concluded, therefore, that the Commission has not adduced proof that the estimated value of the framework
         agreements at issue satisfies the relevant threshold for the application of Directives 92/50 and 2004/18. Against that background,
         the Commission’s action must be dismissed as insufficiently substantiated and, thus, unfounded.
      
      3.      Interim conclusion
      174. In the light of my observations above, I conclude that the Commission has not adduced proof that by reason of the fact that
         local authorities and local authority undertakings awarded directly to the bodies and undertakings mentioned in Paragraph
         6 of the TV-EUmw/VKA service contracts concerning occupational old-age pensions the Federal Republic of Germany has failed
         to fulfil its obligations under Directives 92/50 and 2004/18.
      
      C –    In the alternative: resolution of a conflict between the procurement directives and the fundamental rights to bargain collectively
            and to autonomy in collective bargaining 
      175. If, contrary to the view taken here, the Court concludes that the Commission has adduced proof that one or more local authority
         or local authority undertaking awarded directly to bodies and undertakings mentioned in Paragraph 6 of the TV-EUmw/VKA service
         contracts concerning occupational old-age pensions in contravention of Directive 92/50 or Directive 2004/18, it must be examined,
         in addition, whether, in the light of the fundamental rights to bargain collectively and to autonomy in collective bargaining,
         that incompatibility of the framework agreements concerned vis-à-vis the procurement directives must be regarded as contrary
         to Community law.
      
      176. In that regard, it must be noted, first, that the preliminary selection made in the TV-EUmw/VKA in favour of certain pension
         scheme providers with which conversion of earnings must be implemented is of a restrictive nature. According to Paragraph
         6 of that collective agreement, in principle, conversion of earnings may be implemented only with public bodies offering supplementary
         pensions, savings banks or local authority insurance companies. As a result of those requirements established by collective
         agreement, local authorities are restricted in their ultimate choice of a pension scheme provider such that they can no longer
         freely call for tenders for a framework agreement on the conversion of earnings without also infringing the collective agreement.
      
      177. Thus, a conflict exists between the fundamental rights to bargain collectively and to autonomy in collective bargaining and
         Directives 92/50 and 2004/18. As those procurement directives give effect to freedom of establishment and to freedom to provide
         services, that conflict must be resolved first at a primary law level treating the conflict as one between the fundamental
         rights to bargain collectively and to autonomy in collective bargaining, on the one hand, and freedom of establishment and
         to provide services, on the other. Subsequently, that resolution achieved at a primary law level must implemented at the level
         of secondary law through an interpretation of the procurement directives in accordance with primary law. 
      
      178. Against that background, in the following section, first, I shall address the question of the criteria and yardsticks according
         to which a conflict between fundamental freedoms and fundamental rights must be resolved. On the basis of those criteria and
         yardsticks, I shall subsequently demonstrate how a conflict between freedom of establishment and freedom to provide services
         and the fundamental rights to bargain collectively and to autonomy in collective bargaining may be resolved in the present
         case. That examination allows finally for a determination whether or not the incompatibility of the framework agreements concerned
         vis-à-vis Directives 92/50 and 2004/18, taking account of the obligation to interpret those directives in line with primary
         law, permits a finding that the directives have been infringed.
      
      1.      Resolution of conflicts between fundamental freedoms and fundamental rights: Viking Line and Laval un Partneri
      179. In its recent case-law, the Court tends to resolve conflicts between the exercise of fundamental rights and fundamental freedoms
         by reference to the ‘written’ grounds included in the EC Treaty and the ‘unwritten’ grounds recognised in case-law justifying
         a restriction on fundamental freedoms. 
      
      180. Exemplary in that regard is the judgment in Viking Line. (83) In those proceedings for a preliminary ruling, the Court was required to rule, inter alia, whether a restriction on freedom
         of establishment resulting from collective action initiated by trade unions against a private undertaking was permitted. In
         that regard, the Court held, first, that although the right to take collective action, including the right to strike, must
         be recognised as a fundamental right, (84) the collective action at issue had to be regarded in formal terms as a restriction on freedom of establishment. (85) Then, the Court turned to the question of justification for that restriction. In so doing, it stressed, first, the ‘unwritten’
         justification of ‘overriding reasons in the public interest’, according to which a restriction on freedom of establishment
         may be accepted if it pursues a legitimate aim compatible with the Treaty and is justified by overriding reasons in the public
         interest on condition that the restriction also must be suitable for securing the attainment of the objective pursued and
         must not go beyond what is necessary in order to attain it. (86) Then the Court confirmed that protection of workers counts as one of the overriding reasons in the public interest recognised
         by the Court, (87) subject to the proviso that, naturally, it was for the national court to ascertain whether the objectives pursued by means
         of the collective action concerned the protection of workers. (88) If that were the case, the national court would then have to ascertain if the collective action at issue was suitable for
         ensuring the attainment of the objective pursued and did not go beyond what was necessary to attain that objective. (89)
      
      181. Although in the framework of analysing the justification for restrictions on freedom of establishment the Court referred also
         to the tasks and objectives of the Community in the social policy sphere, (90) ultimately, it did not examine whether, having regard to the principle of proportionality, the exercise as such of the fundamental
         social right to take collective action was apt to justify a restriction on freedom of establishment. Instead, it subsumed
         the fundamental social right to take collective action within the traditional scheme of analysis of the unwritten justification
         of ‘overriding reasons in the public interest’. (91) In that regard, particular emphasis was placed on the notion – inherent in that fundamental right – of protection of workers
         which had already been recognised in consistent case-law as an overriding reason in the public interest. (92)
      
      182. A similar scheme of analysis was employed by the Court in Laval un Partneri, (93) in which, first, it recognised the right to take collective action as a fundamental right; in the subsequent analysis of
         justification for the impairment of the freedom to provide services arising in the scope of the collective action, however,
         it again made reference to the protection of workers as an overriding reason in the public interest.
      
      2.      Equal ranking for fundamental rights and fundamental freedoms and resolution of conflicts on the basis of the principle of
         proportionality 
      
      183. The approach adopted in Viking Line and Laval un Partneri, according to which Community fundamental social rights as such may not justify – having due regard to the principle of proportionality
         – a restriction on a fundamental freedom but that a written or unwritten ground of justification incorporated within that
         fundamental right must, in addition, always be found, sits uncomfortably alongside the principle of equal ranking for fundamental
         rights and fundamental freedoms. 
      
      184. Such an analytical approach suggests, in fact, the existence of a hierarchical relationship between fundamental freedoms and
         fundamental rights in which fundamental rights are subordinated to fundamental freedoms (94) and, consequently, may restrict fundamental freedoms only with the assistance of a written or unwritten ground of justification. (95)
      
      185. In that connection, it must be noted also that the unwritten justification of ‘overriding reasons in the public interest’
         may not apply to justify discriminatory restrictions on fundamental freedoms. (96) Consequently, if the exercise of a fundamental Community right results in a discriminatory restriction on a fundamental freedom,
         under the scheme of analysis adopted in Viking Line and Laval un Partneri, it would have to be examined whether an express justification for restrictions on the fundamental freedom concerned established
         in the EC Treaty applies. That additional limitation on the possibility to justify a restriction on the fundamental freedoms
         would accentuate the existence of a hierarchical relationship between fundamental rights and fundamental freedoms. 
      
      186. In my view, there is no such hierarchical relationship between fundamental freedoms and fundamental rights. (97)
      
      187. In addition, the relationship between fundamental freedoms and fundamental rights is characterised by a broad convergence
         both in terms of structure and content. Thus, it is possible, for example, to formulate the substantive guarantee inherent
         in fundamental freedoms in terms of fundamental rights, in particular, using fundamental rights which protect economic activity.
         In the light of that convergence, it would be a mistake to seek to construct a generally conflictual or hierarchical relationship
         between fundamental rights and fundamental freedoms. (98)
      
      188. Therefore, if in an individual case, as a result of exercising a fundamental right, a fundamental freedom is restricted, a
         fair balance between both of those legal positions must be sought. (99) In that regard, it must be presumed that the realisation of a fundamental freedom constitutes a legitimate objective which
         may limit a fundamental right. Conversely, however, the realisation of a fundamental right must be recognised also as a legitimate
         objective which may restrict a fundamental freedom. 
      
      189. For the purposes of drawing an exact boundary between fundamental freedoms and fundamental rights, the principle of proportionality
         is of particular importance. In that context, for the purposes of evaluating proportionality, in particular, a three-stage
         scheme of analysis must be deployed where (1) the appropriateness, (2) the necessity and (3) the reasonableness of the measure
         in question must be reviewed. (100)
      
      190. A fair balance between fundamental rights and fundamental freedoms is ensured in the case of a conflict only when the restriction
         by a fundamental right on a fundamental freedom is not permitted to go beyond what is appropriate, necessary and reasonable
         to realise that fundamental right. Conversely, however, nor may the restriction on a fundamental right by a fundamental freedom
         go beyond what is appropriate, necessary and reasonable to realise the fundamental freedom. (101)
      
      191. Having regard to the broad convergence between fundamental freedoms and fundamental rights, in the event of a conflict, only
         this analysis based on the principle of proportionality is capable of producing an outcome which ensures the optimum effectiveness
         of fundamental rights and fundamental freedoms.
      
      192. In the light of my observations above, I conclude that a restriction on a fundamental freedom must be regarded as justified
         if that restriction arose in the exercise of a Community fundamental right and was appropriate, necessary and reasonable for
         the attainment of the interests protected by that fundamental right. Conversely, a restriction on a fundamental right must
         be regarded also as justified if that restriction arose in the exercise of a fundamental freedom and was appropriate, necessary
         and reasonable for the attainment of the interests protected by that fundamental freedom.
      
      193. Moreover, confirmation of this approach characterised by an equal ranking of fundamental rights and fundamental freedoms in
         which the principle of proportionality serves as the basis for the resolution of conflicts between the exercise of fundamental
         freedoms and the exercise of fundamental rights would not constitute a fundamental reorientation in the case-law. Instead,
         this analysis implies a return to the values already inherent in Schmidberger. (102) In addition, in Rüffert (103) one can detect the first signs of a need to qualify the approach taken in Viking Line and Laval un Partneri.
      
      194. In Schmidberger, on a reference for a preliminary ruling, the Court had to rule, inter alia, whether a restriction on the free movement of
         goods resulting from a 30-hour blockade of the Brenner motorway could be justified having regard to the fact that such blockade
         constituted the legitimate exercise of the fundamental rights to freedom of expression and freedom of assembly. In order to
         resolve that conflict between the fundamental rights at issue and the free movement of goods, in essence, the Court examined
         whether the impairments to intra-Community trade arising through the exercise of fundamental rights were proportionate to
         the protection of those rights. (104) Conversely, it was examined also whether strict enforcement of the free movement of goods would have resulted in an excessive
         interference in the exercise of the fundamental rights. (105) As both questions were answered in the affirmative, the restriction on the free movement of goods arising through the exercise
         of the fundamental rights at issue, ultimately, had to be regarded as justified.
      
      195. Accordingly, central to Schmidberger was the idea of equal ranking for conflicting fundamental rights and fundamental freedoms which, ultimately, by an examination
         of the proportionality of the opposing restrictions in question, were brought fairly into balance. 
      
      196. At this point, finally, Rüffert (106) should not go unmentioned, in which on a reference for a preliminary ruling the Court ruled, inter alia, on the compatibility
         with Article 49 EC of the Niedersächsisches Landesvergabegesetz (Law of Land Niedersachsen on the award of public contracts).
         
      
      197. In that regard, the Court held, first, that requirements established by that law obliging contracting authorities to designate
         as contractors for public works contracts only contractors which, when submitting their tenders, agree in writing to pay their
         employees, in return for performance of the services concerned, at least the wage provided for in the collective agreement
         in force at the place where those services are performed, even where that collective agreement is not capable of being treated
         as universally applicable, are capable of constituting a restriction within the meaning of Article 49 EC. In the framework
         of its examination whether such restriction could be considered to be justified, the Court examined subsequently three ‘unwritten’
         grounds of justification. In particular, it was examined whether the restriction could be justified (1) by the objective of
         ensuring the protection of workers, (2) by the objective of ensuring protection for independence in the organisation of working
         life by trade unions, or (3) by the objective of ensuring the financial stability of social security systems. 
      
      198. Although, ultimately, the Court held the restriction on the freedom to provide services not to be justified, above all, the
         examination of justification from the perspective of ensuring ‘protection for independence in the organisation of working
         life by trade unions’ appears to me to be particularly important. Whilst in the concepts of the ‘objective of ensuring protection
         of workers’ and the ‘objective of ensuring the financial stability of social security systems’ reference was had to two overriding
         reasons in the public interest recognised in settled case-law, (107) in examining the ‘protection for independence in the organisation of working life by trade unions’ the Court considered,
         at least, implicitly, the possibility that the fundamental social right to freedom of association, in itself, could justify
         a restriction on fundamental freedoms.
      
      199. In the light of the foregoing, I conclude that a restriction on a fundamental freedom is justified, when that restriction
         arose in the exercise of a fundamental right and was appropriate, necessary and reasonable for the attainment of interests
         protected by that fundamental right. As a mirror image thereof, a restriction on a fundamental right is justified, when that
         restriction arose in the exercise of a fundamental freedom and was appropriate, necessary and reasonable for the attainment
         of interests protected by that fundamental freedom.
      
      3.      Resolution of the conflict between Directives 92/50 and 2004/18 and the fundamental rights to bargain collectively and to
         autonomy in collective bargaining 
      
      200. If the Court were to conclude that one or more local authority or local authority undertaking awarded directly to bodies and
         undertakings mentioned in Paragraph 6 of the TV-EUmw/VKA service contracts concerning occupational old-age pensions contrary
         to the provisions of Directive 92/50 or Directive 2004/18, it would be clear that, in formal terms, those procurement directives
         preclude the manner in which, in fact, the fundamental rights to bargain collectively and to autonomy in collective bargaining
         were exercised. In that sense, there would be an impairment of those fundamental social rights as a result of the procurement
         directives because the social partners would no longer be capable of freely exercising those fundamental social rights but
         would be tied – from a procurement law perspective – to certain requirements.
      
      201. The conflict thus produced between Directives 92/50 and 2004/18 and those fundamental social rights must be resolved, first,
         in examining at the level of primary law whether freedom of establishment and freedom to provide services allow for such a
         restriction of those fundamental social rights. If that question must be answered in the affirmative, there is nothing to
         preclude the finding that the framework agreements in question contravene Directives 92/50 and 2004/18 which give effect to
         freedom of establishment and freedom to provide services. If, however, that question must be answered in the negative, it
         would have to be ensured through an interpretation of those directives in conformity with primary law that the framework agreements
         in question fall outside the scope of Directives 92/50 and 2004/18.
      
      202. For the purposes of ascertaining whether freedom of establishment and freedom to provide services allow for such restriction
         on the fundamental rights to bargain collectively and to autonomy in collective bargaining as is provided for in the procurement
         directives, in principle, it must be examined whether in order to attain the objectives pursued by the fundamental freedoms
         such a restriction is appropriate, necessary and reasonable.
      
      203. However, in the present proceedings, the German Government advanced, above all, arguments seeking to justify a restriction
         on freedom of establishment and freedom to provide services by fundamental social rights. 
      
      204. The assessment of whether freedom of establishment and freedom to provide services may justify a restriction on the fundamental
         rights to bargain collectively and to autonomy in collective bargaining constitutes, ultimately, the mirror image of the assessment
         of whether those fundamental social rights may justify a restriction on freedom of establishment and freedom to provide services.
         As the latter option for analysis facilitates a thorough evaluation of the arguments advanced by the German Government, in
         the following section I will examine whether for the attainment of the objectives pursued by the fundamental rights to bargain
         collectively and to autonomy in collective bargaining it was necessary to restrict fundamental freedoms in the manner contested
         by the Commission.
      
      205. By their nature, the fundamental rights to bargain collectively and to autonomy in collective bargaining are intended to ensure
         that employers or employers’ organisations, on the one hand, and workers’ organisations, on the other, in the framework of
         voluntary negotiations and in complete independence, respecting certain limits and requirements, may negotiate and subsequently
         record in an appropriate form workers’ terms and conditions of employment. (108)
      
      206. Thus, having regard to the principle of proportionality, the restriction on freedom of establishment and freedom to provide
         services arising as a result of the preliminary selection in Paragraph 6 of the TV-EUmw/VKA in favour of certain pension scheme
         providers would have to be considered justified by the fundamental rights to bargain collectively and to autonomy in collective
         bargaining, if that preliminary selection of pension scheme providers was appropriate and necessary to permit voluntary and
         independent negotiations on terms and conditions of employment with a view to the conclusion of a collective agreement and
         the infringement of fundamental freedoms thereby occasioned was proportionate to the attainment of those objectives.
      
      207. A measure is appropriate to ensuring the attainment of the objective in question if it genuinely reflects a concern to attain it in a consistent and
         systematic manner. (109)
      
      208. Having regard to the fact that the principle of concentrating the conversion of earnings to a limited number of pension scheme
         providers was incorporated in the TV-EUmw/VKA, it must be presumed that such principle constitutes part of a compromise reached
         in the framework of voluntary and independent negotiations between the representatives of employers and those of workers.
         At any rate, the case-file does not include any information to permit an alternative conclusion. Against that background,
         the preliminary selection in Paragraph 6 of the TV-EUmw/VKA in favour of certain pension scheme providers must be considered
         a measure which is appropriate to ensure the attainment of the interests protected by the fundamental rights to bargain collectively
         and to autonomy in collective bargaining.
      
      209. A measure is necessary if, from among several measures which are appropriate for meeting the objective pursued, it is the least onerous for the
         interest or legal right in question. (110)
      
      210. Having regard to the peculiarities of the present case, evaluation of the necessity of the preliminary selection in Paragraph
         6 of the TV-EUmw/VKA in favour of certain pension scheme providers logically presupposes the verification of whether, in the
         framework of collective bargaining, an alternative consensus on the implementation of conversion of earnings could conceivably
         have been achieved. Only if the social partners could have achieved an alternative consensus, conforming more closely to Community
         law, could the preliminary selection at issue in favour of certain pension scheme providers be rejected as unnecessary.
      
      211. In answering the question whether in the framework of voluntary and independent negotiations the social partners could have
         achieved an alternative consensus on the implementation of conversion of earnings, the Court must proceed with great caution.
         Although for the purposes of resolving a conflict between fundamental freedoms and the fundamental rights to bargain collectively
         and to autonomy in collective bargaining an examination of the substance of collective agreements may – as in the present
         case – also be required, in that regard, the Court must respect as far as possible the social partners’ scope for assessment
         and action. (111)
      
      212.  Thus, in the present case, the assessment of necessity must be limited to evaluating whether an implementation measure, conforming
         more closely to Community law, could have been achieved and if the social partners could have achieved such evident consensus
         on that measure that no substantive arguments would have countered its adoption. Should those questions be answered in the
         affirmative, the preliminary selection in Paragraph 6 of the TV-EUmw/VKA in favour of certain pension scheme providers would
         have to be rejected as unnecessary and, thus, disproportionate.
      
      213. In my view, it would have been possible without more to have structured the agreements on the implementation of conversion
         of earnings in conformity with Community law. 
      
      214. In that connection, it must be stressed that the action brought by the Commission does not contest the principle of conversion
         of earnings in itself but simply the fact that the collective agreement imposes on local authority employers a selection of
         pension scheme providers for the purposes of implementing the conversion of earnings notwithstanding the fact – assuming that
         the procurement directives apply – that such employers in their capacity as contracting authorities are required, in accordance
         with those directives, to launch an invitation to tender. 
      
      215. In those circumstances, it is possible to conceive of an alternative scheme compliant with Community law in which, within
         the framework of the implementation methods provided for the BetrAVG, conversion of earnings would have to be implemented
         through one or more pension scheme providers selected by local authority employers in accordance with the primary law obligation
         of transparency (112) or, where the conditions for their application are satisfied, with the procurement law directives. 
      
      216. The question whether in the present proceedings substantive arguments have been advanced to counter such a provision of a
         collective agreement on the implementation of conversion of earnings in conformity with Community law must, in my view, be
         answered in the negative. 
      
      217. For the purposes of justifying the preliminary selection in Paragraph 6 of the TV-EUmw/VKA in favour of certain pension scheme
         providers, the German Government stresses that under the BetrAVG it is, in principle, for the employer to select the pension
         scheme provider to implement the conversion of earnings not based on a collective agreement. By way of derogation, in relation
         to earnings based on a collective agreement, Paragraph 17(5) of the BetrAVG provides that conversion of such necessitates
         a collectively agreed scheme, thereby ensuring, in the view of the German Government, in particular, that workers are granted
         a greater influence over the arrangements for their occupational old-age pensions. In that regard, Paragraph 17(3) of the
         BetrAVG grants to the social partners the possibility, inter alia, to determine by mutual agreement the selection of the pension
         scheme provider for the purposes of implementing the conversion of earnings based on a collective agreement, as has been effected,
         in fact, in Paragraph 6 of the TV-EUmw/VKA. That preliminary selection, reached by common accord, in favour of certain pension
         scheme providers serves, in the view of the German Government, both the interests of workers in the establishment of a transparent
         scheme for the implementation of conversion of earnings and the interests of employers in an old-age pension scheme which
         requires little administrative effort. Ultimately, so they argue, shifting that decision into the realm of the social partners
         thereby contributes to ensuring the broadest possible acceptance and take-up of that form of occupational old-age pension.
         
      
      218. In addition, the German Government argues that, according to the view of the social partners, limiting the pool from which
         an employer may select providers for the conversion of earnings is intended to improve the transparency and popularity of
         supplementary occupational old-age pensions. Moreover, Paragraph 6 of the TV-EUmw/VKA simplifies matters for an individual
         employer as a comparison between pension scheme providers is no longer necessarily required. In addition, argues the German
         Government, an individual local authority employer may presume that the social partners’ selection of pension scheme providers
         was not arbitrary and that, as a rule, the social partners had a better overview of the market situation. Conversely, workers
         could rely on the fact that in the selection of pension scheme providers the trade unions adequately represented their interests.
         Accordingly, so the German Government argues, Paragraph 6 of the TV-EUmw/VKA protects workers against an ‘unsatisfactory’
         and unilateral selection by the employer of the pension scheme provider.
      
      219. As specific justification for the selection made in Paragraph 6 of the TV-EUmw/VKA in favour of public bodies offering supplementary
         pensions, the Sparkassen finance group and local authority insurance companies, the German Government argues, in addition,
         that these were nominated for good reasons such as, for example, positive experience, particular confidence and reduced administrative
         costs resulting from the particular structure of those pension scheme providers. In addition, the employers’ interest in limiting
         the risk of their liability for default also influenced that decision.
      
      220. In the light of those observations, the substantive arguments advanced by the German Government in justification of the scheme
         provided for in Paragraph 6 of the TV-EUmw/VKA may be summarised in four categories, that is (1) transparency in the selection
         of pension scheme providers, (2) greater acceptance amongst workers as a result of the participation of worker representatives
         in the preliminary selection in favour of certain pension scheme providers, (3) the greater expertise of the parties involved
         in negotiating the collective agreement and (4) particular characteristics of the chosen pension scheme providers.
      
      221. Those arguments are, however, wholly unsuited to be invoked as substantive grounds with which to counter the adoption by collective
         agreement of an implementation scheme in conformity with Community law in which individual local authority employers must
         select pension scheme providers in accordance with the primary law requirement of transparency or, where the conditions for
         their application are satisfied, with the procurement law directives.
      
      222. The argument concerning the transparency of the choice of the pension scheme providers does not point against but in favour
         of an obligation on local authority employers to respect Community law requirements. The primary law obligation of transparency
         and the procurement directives are intended precisely to ensure sufficient transparency in the selection of the pension scheme
         providers with which conversion of earnings must be effected.
      
      223. Nor does the argument of greater interest amongst workers resulting from the participation of worker representatives in the
         preliminary selection in favour of certain pension scheme providers imply a substantive reason opposing an implementation
         scheme in conformity with Community law. In fact, the obligation to respect the primary law obligation of transparency and
         the procurement law directives would trigger more intensive Community-scale competition between pension scheme providers and,
         hence, would constitute a particular guarantee that, ultimately, the most advantageous scheme for the implementation of conversion
         of earnings would be offered to workers. It is not apparent how this could result in a reduced level of interest amongst workers. (113)
      
      224. The third main argument of the German Government concerns local authority employers for which the preliminary selection in
         Paragraph 6 of the TV-EUmw/VKA simplifies the ultimate decision in favour of one or more pension scheme provider and, in that
         regard, allows those employers to rely also on the expertise of the social partners.
      
      225. Even if, as a result of the preliminary selection established in Paragraph 6 of the TV-EUmw/VKA, local authority employers
         are spared, in fact, the task of launching a separate invitation to tender, that does not constitute a reliable argument with
         which to counter an obligation to respect the primary law obligation of transparency and the procurement directives. Even
         if, as a result of the obligation to respect Community law, employers were less interested in the determination of a collectively
         agreed scheme for the implementation of conversion of earnings – an argument not advanced by the German Government – that
         could not be invoked as substantive grounds on which to oppose the determination of such obligation by way of collective agreement.
         Such an argument, in fact, would result in the situation that local authority employers could exploit the right to autonomy
         in collective bargaining in order to circumvent mandatory requirements of Community law.
      
      226. By its fourth main argument, the German Government refers finally to special features of the selected pension scheme providers.
         In its view, factors in favour of the selection of those pension scheme providers are, in particular, the positive experiences
         had with those bodies, the particular confidence thereby resulting, low administrative costs deriving from their particular
         structure and the reduced risk of default. However, the German Government has in no way substantiated those arguments such
         that for that reason alone they must be rejected as unfounded. (114)
      
      227. In the light of those observations, I conclude that the restriction on pension scheme providers established in Paragraph 6
         of the TV-EUmw/VKA was unnecessary to facilitate voluntary and independent negotiations between the social partners on terms
         and conditions of employment with a view to the conclusion of a collective agreement.
      
      228. In addition, the preliminary selection adopted by the social partners in Paragraph 6 of the TV-EUmw/VKA in favour of certain
         pension scheme providers results, in my view, in an unreasonable restriction on fundamental freedoms.
      
      229. In the context of the assessment of reasonableness in the present case, it must be observed in particular that the action brought by the Commission does not contest the principle
         of conversion of earnings in itself but simply the fact that for local authority employers collective agreement prescribes
         their choice of pension scheme provider for the implementation of conversion of earnings notwithstanding the fact that such
         employers, in their capacity as contracting authorities, must respect the requirements resulting from the principles of freedom
         of establishment and freedom to provide services.
      
      230. Consequently, the present proceedings do not concern the fundamental decision taken by collective agreement to allow for conversion
         of earnings but the seemingly technical question – from the point of view of the law on collective agreements – of how to
         select the pension scheme providers with which conversion of earnings must be implemented. However, in adopting the preliminary
         selection of Paragraph 6 of the TV-EUmw/VKA in regulation of that seemingly technical question, the social partners have attempted
         to exclude in their entirety the requirements resulting from the principles of freedom of establishment and freedom to provide
         services.
      
      231. Having regard to the fact that the requirements included in Paragraph 6 of the TV-EUmw/VKA must be regarded as technical implementing
         provisions hardly touching on terms and conditions of employment whilst at the same time their effect is to exclude in their
         entirety the requirements resulting from the principles of freedom of establishment and freedom to provide services, the restriction
         on the fundamental freedoms resulting from Paragraph 6 of the TV-EUmw/VKA must be categorised as unreasonable. (115)
      
      232. Thus, in the light of the foregoing, it must be concluded that the preliminary selection of pension scheme providers in Paragraph
         6 of the TV-EUmw/VKA was neither necessary nor reasonable for ensuring the attainment of the objectives protected by the fundamental
         rights to bargain collectively and to autonomy in collective bargaining.
      
      233. In the light of those considerations, I conclude that the fundamental rights to bargain collectively and to autonomy in collective
         bargaining are incapable of justifying the restriction on freedom of establishment and freedom to provide services resulting
         from the preliminary selection adopted by the social partners in Paragraph 6 of the TV-EUmw/VKA in favour of certain pension
         scheme providers because such restriction is not proportionate. Consequently, nor do those fundamental rights preclude the
         finding that the framework agreements in question concluded in implementation of that collective agreement may infringe Directives
         92/50 and 2004/18.
      
      4.      Interim conclusion
      234. If, contrary to the view I have taken, the Court concludes that in concluding framework agreements on the conversion of earnings
         with one or more of the bodies and undertakings mentioned in Paragraph 6 of the TV-EUmw/VKA one or more local authority or
         local authority undertaking contravened Directive 92/50 or Directive 2004/18, it would have to be presumed, having regard
         to the above analysis, that, owing to an absence of proportionality, the fundamental rights to bargain collectively and to
         autonomy in collective bargaining do not preclude a finding of such an infringement of those directives. 
      
      VIII –  Summary
      235. In summary, I conclude that in concluding the framework agreements in question on occupational pension provision for their
         employees German local authorities were obliged to respect the provisions of Directive 92/50 or Directive 2004/18 to the extent
         that the material and personal requirements of those directives were satisfied. However, it is incumbent on the Commission
         to prove that the scope of the procurement directives was triggered and, in doing so, it may not rely on presumptions.
      
      236. For the purposes of reaching a decision in the present proceedings, ultimately, the crucial fact is that in its calculations
         on the value of each individual framework agreement and on meeting the relevant thresholds for the application of the procurement
         directives the Commission relied on the presumption that each city of a certain size concluded only one framework agreement.
         As already in the pre-litigation procedure the German Government contested the correctness of that presumption and, in that
         connection, it cannot be alleged in any way that it failed to cooperate in the proper investigation of the facts, ultimately,
         the Commission’s action must be dismissed as insufficiently substantiated and, thus, unfounded.
      
      IX –  Conclusion
      237. In the light of the foregoing conclusions, I propose that the Court should:
      
      (1)      dismiss the action;
      (2)      order the Commission to pay the costs, with the exception of the costs incurred by the Kingdom of Denmark and the Kingdom
         of Sweden. The Kingdom of Denmark and the Kingdom of Sweden shall pay their own costs.

      14 –	See Joined Cases C-180/98 to C-184/98 Pavlov and Others [2000] ECR I-6451, paragraph 67 et seq., in which the Court emphasised that the exclusion of collective agreements from the
         scope of Article 81(1) EC cannot be extended to an agreement which, whilst being intended to guarantee a certain level of
         pension to all the members of a profession and thus to improve one aspect of their working conditions, namely their remuneration,
         is not concluded in the context of collective bargaining between employers and workers.

      17 –	Cited above in footnote6.
      
      18 –	This substantive control of collective agreements was proposed by Advocate General Jacobs in his Joined Opinion in Case
         C-67/96 Albany, Joined Cases C‑115/97 to C-117/97 Brentjens’ and Case C-219/97 Drijvende Bokken [1999] ECR I-5751, point 190 et seq., to avoid collective negotiations being used as a framework for agreements between employers
         with seriously anti-competitive effects on third parties or third markets. According to Advocate General Jacobs, the outcome
         of collective negotiations should be regarded as falling outside the scope of competition rules only if (1) the agreement
         was made in the formal framework of collective bargaining and (2) was concluded by the social partners in good faith. In addition,
         as a third criterion, Advocate General Jacobs proposed that collective agreements must deal with the core subjects of collective
         bargaining such as wages and working conditions and not directly affect third parties or markets. 
      
      19 –	In that connection, it should be especially observed that the virtual absence of any substantive examination of the provisions
         of the collective agreements concerned has to be viewed in the context of the Court’s subsequent assessment of whether the
         pension funds mentioned by the social partners constituted undertakings for the purposes of Article 81 EC. Given the Court’s
         ultimate finding in Albany, Brentjens’ and Drijvende Bokken that those funds displayed the characteristics of undertakings, that allowed for a separate assessment of the anti-competitive
         effects resulting from the funds concerned. In so doing, ultimately, this qualified the limitation on the scope of competition
         law in relation to the collective agreements in question.

         action as a fundamental social right. In the view of Azoulai, L., ‘The Court of Justice and the social market economy: the
         emergence of an ideal and the conditions for its realisation’, CMLR 2008, p. 1335, at p. 1347 et seq., there is, in fact, a fundamental difference between the relationship between fundamental
         freedoms and fundamental rights as expressed in Albany and that same relationship as expressed in Viking Line.

      28 –	Article 6 of the European Social Charter, adopted verbatim in Article 6 of the revised European Social Charter signed in
         Strasbourg on 3 May 1996, with a view to ensuring the effective exercise of the right to bargain collectively obliges the
         signatory parties, inter alia, to promote joint con­sulta­tion between workers and employ­ers and to promote, where necessary
         and appropri­ate, machinery for voluntary negotia­tions between employers or employers’ organi­sations and workers’ organisations,
         with a view to the regulation of terms and conditions of employment by means of collective agreements.
      
      29 –	According to point 12 of the Community Charter of the Fundamental Social Rights of Workers, employers or employers’ organisations,
         on the one hand, and workers’ organisations, on the other, shall have the right to negotiate and conclude collective agreements
         under the conditions laid down by national legislation and practice.  
      
      30 –	According to Article 28 of the Charter of Fundamental Rights of the European Union, workers and employers, or their respective
         organisations, have, in accordance with Community law and national laws and practices, the right to negotiate and conclude
         collective agreements at the appropriate levels and, in cases of conflicts of interest, to take collective action to defend
         their interests, including strike action. 
      
      31 –	On that point, see, for example, Case C-341/05 Laval un Partneri [2007] ECR I‑11767, paragraphs 90 and 91, and Viking Line, cited above in footnote 22, paragraphs 43 and 44, in which having regard to its recognition in the European Social Charter,
         Convention No 87 of the International Labour Organisation concerning Freedom of Association and the Right to Organise, the
         Community Charter of the Fundamental Social Rights of Workers and the Charter of Fundamental Rights of the European Union,
         the right to take collective action, closely connected to the right to bargain collectively, was recognised as a fundamental
         right. 
      
      32 –	On that point, see, for example, Schwarze, J., ‘Der Reformvertrag von Lissabon – Wesentliche Elemente des Reformvertrags’,
         EuR 2009 (Supplement No 1), p. 9, at p. 17, who points out, in my view, correctly, that the fact that Article 6 TEU includes simply
         a general reference to the charter is not relevant in legal terms and cannot be used as an argument to contest the incorporation
         of the Charter of Fundamental Rights in primary law. However, Protocol No 30 on the Application of the Charter of Fundamental
         Rights of the European Union to Poland and the United Kingdom provides for a derogation for Poland and the United Kingdom.
      
      33 –	It is now settled case-law of the Court that protection of fundamental rights constitutes a legitimate interest which,
         in principle, justifies a restriction of the obligations imposed by a fundamental freedom guaranteed in primary law; see Laval un Partneri, cited above in footnote 31, paragraph 93; Viking Line, cited above in footnote 22, paragraph 45; Omega, cited above in footnote 27, paragraph 35; and Schmidberger, cited above in footnote 27, paragraph 74. However, that does not imply that acts which must be regarded as the exercise
         of a fundamental right, eo ipso, fall outside the scope of the fundamental freedoms. Instead, fundamental rights must be exercised, as far as possible, in
         accordance with the rights and freedoms protected by the Treaty, and, in that regard, every conflict between fundamental rights
         and obligations resulting from the fundamental freedoms must be resolved having regard to the specific features of the fundamental
         rights and fundamental freedoms concerned in accordance with the principle of proportionality. See point 183 et seq. of this

      42 –	On the other hand, if a contracting authority seeks in a capacity as a provider of services itself to exercise an independent
         economic activity subject to competition and in that connection enters into competition with private economic actors, the
         possibility cannot be precluded that its decision to subcontract a part of the activities to a particular third party is guided
         by considerations other than economic ones. Consequently, in such a case the procurement directives apply without limitation.

      50 –	Article 1(5) of Directive 2004/18 paraphrases a framework agreement as ‘an agreement between one or more contracting authorities
         and one or more economic operators, the purpose of which is to establish the terms governing contracts to be awarded during
         a given period, in particular with regard to price and, where appropriate, the quantity envisaged’. Although that general
         formulation does not state directly that those framework agreements usually contain the terms for future contracts awarded
         by the contracting authority, it clearly follows from recital 11 in the preamble that the legislature started from that premiss.

         of the procurement directives points in favour of the application of procurement law. In addition, that author discusses the
         possibility to treat the fact that the employer introduces its employees to a pension scheme provider as supplying a pecuniary
         interest.

      64 –	On that point, see Article 9(2) of Directive 2004/18, according to which the estimate of the value of the public contract
         must be valid at the moment at which the contract notice is sent, as provided for in Article 35(2) or, in cases in which such
         notice is not required, at the moment at which the contracting authority commences the contract awarding procedure.

         authority providers of supplementary pensions concerning the conversion of earnings, the results of which are attached as
         Annex 2 to the rejoinder of the German Government, it follows that the average proportion of local authority workers who in
         2003 had already exercised the option to convert earnings was 0.61%, each contributing by way of earnings conversion an average
         of EUR 61.28 monthly. That presupposes, naturally, that in 2003 local authority employers had concluded framework agreements
         with pension scheme providers.

         than fundamental rights. See Vigneau, C., ‘Encadrement par la Cour de l’action collective au regard du Traité de Rome’, La Semaine Juridique – éd. gén 2008, II 10060, p. 33, at pp. 34 and 35, who argues that in those judgments the Court of Justice recognised the right to
         take collective action as a ‘secondary fundamental right’. Zwanziger, B, ‘Arbeitskampf- und Tarifrecht nach den EuGH-Entscheidungen
         “Lavalˮ und “Vikingˮ’, DB 2008, p. 294, at p. 295, argues that in comparison with the approach to reconciling fundamental rights and fundamental freedoms
         adopted in Schmidberger, cited above in footnote 27, in Viking Line and Laval un Partneri a shift of emphasis in favour of fundamental freedoms was effected.  
      
      95 –	In that connection, academic writings stress, in addition, that in accordance with consistent case-law of the Court – which
         holds that Articles 39 EC, 43 EC and 49 EC extend also to rules of any other nature aimed at regulating in a collective manner
         gainful employment, self-employment and the provision of services (see on that issue point 66 of this Opinion) – under certain
         conditions, trade unions and other non-governmental associations and bodies may be alleged also to have infringed fundamental
         freedoms, but that the case-law concerning written and unwritten grounds of justification was developed primarily in connection
         with Member State infringements of fundamental freedoms. As a result, so the argument goes, for such non-governmental associations
         it is generally difficult to adduce proof of justification; see Davies, A.C.L., cited above in footnote 91, p. 142. This could
         be regarded as an asymmetrical development of Community law.

         S.E.W. 2008, p. 425, at pp. 434 and 435, who point to the fact that a conflict between fundamental rights and fundamental freedoms
         can often be reformulated as a conflict between two fundamental rights.
      
      99 –	See, for example, Rengeling, H.W. and Szczekalla, P., Grundrechte in der Europäischen Union, Cologne, 2004, point 1008, who emphasise in relation to the right to take collective action – now recognised as a Community
         fundamental right and closely connected to the fundamental right to autonomy in collective bargaining – that any conflicts
         between fundamental freedoms and that right to take collective action must be resolved by a process of reconciliation.

      101 –	That assessment accords with the principles incorporated in Article 52(1) of the Charter of Fundamental Rights of the European
         Union. According to Article 52(1) of the Charter of Fundamental Rights, any limitation on the exercise of the rights and freedoms
         recognised by that charter must be provided for by law and respect the essence of those rights and freedoms. Subject to the
         principle of proportionality, limitations may be made only if they are necessary and genuinely meet objectives of general
         interest recognised by the Union or the need to protect the rights and freedoms of others.

      111 –	Naturally, at this point it should be recalled that in consistent case-law the Court has examined the substance of collective
         agreements with regard to compliance with the prohibition on discrimination established in Article 39 EC and in Council Regulation
         (EEC) No 1612/68 of 15 October 1968 on freedom of movement for workers within the Community (OJ, English Special Edition 1968
         (II), p. 475). Such substantive control of collective agreements is expressly provided for in Article 7(4) of that regulation.
         See Case C-400/02 Merida [2004] ECR I-8471; Case C-35/97 Commission v France [1998] ECR I-5325; and Case C‑15/96 Schöning-Kougebetopoulou [1998] ECR I-47. 
      
      112 –	According to consistent case-law, the primary law obligation of transparency requires a sufficient degree of advertising
         to be ensured for the benefit of any potential contractor. However, it does not necessarily imply an obligation to launch
         an invitation to tender; see Case C-324/07 Coditel Brabant [2008] ECR I-8457, paragraph 25, and Case C-231/03 Coname [2005] ECR I-7287, paragraph 21. 
      
      113 –	See also Hanau, P., ‘Tarifvertragliche Beschränkungen der Entgeltumwandlung’, DB 2004, p. 2266, at p. 2268, who, drawing attention to one of the general principles of German law on collective agreements,
         that is, the principle that derogations which are more favourable to workers are permitted (Günstigkeitsprinzip), in a particularly pertinent manner, questions the restriction on pension scheme providers established by Paragraph 6 of
         the TV-EUmw/VKA. In his view, it would be quite simply absurd to presuppose that a collective agreement might preclude local
         authority employers from concluding agreements on conversion of earnings more favourable to workers and, in particular, regardless
         of whether such alternative scheme is more favourable in terms of the direct contributions made by the employer or in terms
         of the benefits offered by the pension scheme provider. As he points out, the purpose of collective agreements is worker protection.
      
      114 –	In that connection, it must be noted that leading academic commentators are highly critical of the preliminary selection
         of pension scheme providers established by Paragraph 6 of the TV-EUmw/VKA. See, in particular, Hanau, P., cited above in footnote
         113, p. 2269, who takes the view that the restrictions in the TV-EUmw/VKA on the pension scheme providers authorised to implement
         conversion schemes appear to favour only the interests of pension scheme providers and not those of workers.
      
      115 –	On that point, see Jarass, D., EU-Grundrechte, Munich, 2005, p. 344, who takes the view that restrictions on the rights to bargain collectively and to take collective
         action are possible in particular in those areas in which collective bargaining does not concern terms and conditions of employment.
