      VIII –  Conclusion
      I –  Introduction
      1.        In this reference for a preliminary ruling the High Court of Justice of England and Wales (‘the referring court’) has asked
         the Court of Justice of the European Communities two questions on the implementation at national level of Council Regulation
         (EC) No 1782/2003 of 29 September 2003 establishing common rules for direct support schemes under the common agricultural
         policy and establishing certain support schemes for farmers. (2)
      
      2.        The first question concerns the interpretation of Article 5(1) of and Annex IV to Regulation No 1782/2003. The referring court
         specifically seeks to ascertain whether a Member State is permitted to include requirements relating to the maintenance of
         visible public rights of way in the standards of good agricultural and environmental condition of land set out therein. With
         its second question, the referring court would like to know whether it can give rise to impermissible discrimination for constituent
         parts of a Member State to have different standards of good agricultural and environmental condition under Article 5 of and
         Annex IV to Regulation No 1782/2003 because a Member State’s internal constitutional arrangements provide that different devolved
         administrations are to have legislative competence in relation to different constituent parts of that Member State.
      
      3.        This reference has been made in a dispute between Mr Horvath (‘the applicant’) and the Secretary of State for Environment,
         Food and Rural Affairs (‘the defendant’) concerning the lawfulness of a national implementing regulation which defines the
         minimum requirements for good agricultural and environmental condition of agricultural land for the territory of England.
      
      II –  Legal framework
      A –    Community law
      4.        On 29 September 2003 the Council adopted Regulation No 1782/2003, which entered into force on 28 October 2003.
      
      5.        The regulation was adopted an order to provide for a policy of supporting farmers’ incomes by means of a single payment scheme
         (‘the single payment scheme’). The single payment scheme is intended to provide farmers with a minimum guaranteed income,
         ‘decoupled’ from production, by allocating to farmers ‘payment entitlements’ against which they may claim a direct payment
         annually. Receipt of the annual direct payment under the single payment scheme – if claimed by the farmer – is subject to
         ‘cross-compliance’ conditions (Article 3).
      
      6.        The cross-compliance conditions comprise two elements: the ‘statutory management requirements’ (Article 4), to be established
         by Community legislation, and ‘good agricultural and environmental condition’ (Article 5).
      
      7.        Article 5(1) of the regulation provides:
      
      ‘Member States shall ensure that all agricultural land, especially land which is no longer used for production purposes, is
         maintained in good agricultural and environmental condition. Member States shall define, at national or regional level, minimum
         requirements for good agricultural and environmental condition on the basis of the framework set up in Annex IV, taking into
         account the specific characteristics of the areas concerned, including soil and climatic condition, existing farming systems,
         land use, crop rotation, farming practices, and farm structures. This is without prejudice to the standards governing good
         agricultural practices as applied in the context of Council Regulation (EC) No 1257/1999 and to agri-environment measures
         applied above the reference level of good agricultural practices.’
      
      8.        If the cross-compliance conditions are not satisfied, the total amount of direct payments to be granted in the calendar year
         in question is to be reduced or cancelled pursuant to Article 6(1) of Regulation No 1782/2003.
      
      9.        Annex IV to the regulation states:
      
      ‘Good agricultural and environmental condition referred to in Article 5
      
      
               Issue
            
            
               Standards
            
         
               Soil erosion:
               Protect soil through appropriate measures
            
            
               – Minimum soil cover
               – Minimum land management reflecting site-specific conditions
               – Retain terraces
            
         
               Soil organic matter:
               Maintain soil organic matter levels through appropriate practices
            
            
               – Standards for crop rotations where applicable
               – Arable stubble management
            
         
               Soil structure:
               Maintain soil structure through appropriate measures
            
            
               – Appropriate machinery use
            
         
               Minimum level of maintenance:
               Ensure a minimum level of maintenance and avoid the deterioration of habitats
            
            
               – Minimum livestock stocking rates or/and appropriate regimes
               – Protection of permanent pasture
               – Retention of landscape features
               – Avoiding the encroachment of unwanted vegetation on agricultural land’
            
         
      B –    National law
      10.      In 1998, the United Kingdom Parliament passed primary legislation whereby provision was made for a system of devolved government
         in relation to Wales, Northern Ireland and Scotland. In relation to devolved matters, the United Kingdom Government generally
         acts only in respect of England.
      
      11.      The statutory relationship between the United Kingdom Government and the devolved administrations is supplemented by a ‘Devolution
         Memorandum of Understanding’, which seeks to provide further detailed arrangements for that relationship in the form of a
         statement of political intent. Under the terms of the devolution legislation and the Memorandum of Understanding, it is the
         responsibility of the devolved administrations to implement obligations under Community law which concern devolved matters.
         Under the devolution legislation, United Kingdom ministers have reserve powers to intervene where it is necessary to do so
         in order to ensure the implementation of these obligations. Under the devolution legislation, it is unlawful for the devolved
         administrations to act or legislate in any way that would be incompatible with Community law. The devolved administrations
         are directly accountable through the domestic courts, in the same way as the United Kingdom Government is, for shortcomings
         in their implementation or application of Community law.
      
      12.      In principle, the common agricultural policy in general and the implementation of Regulation No 1782/2003 in particular are
         devolved matters and are therefore the responsibility of each devolved administration. As a result, and with a view to complying
         with their obligations under Article 5 of the regulation, the defendant (acting in relation to England alone) and each of
         the devolved administrations adopted separate implementing regulations, defining partly different minimum requirements for
         good agricultural and environmental condition.
      
      13.      The relevant implementing regulation for England is the Common Agricultural Policy Single Payment and Support Schemes (Cross
         Compliance) (England) Regulations 2004, SI 2004/3196 (‘the English implementing regulations’), which entered into force in
         England on 1 January 2005. 
      
      14.      In paragraphs 26 to 29 of the English implementing regulations, the defendant included requirements relating to the maintenance
         of public rights of way in the standards of good agricultural and environmental condition. They are defined inter alia as
         follows:
      
      ‘26.      A farmer must not
      (a)      without lawful authority or excuse, disturb the surface of a visible footpath, a visible bridleway, or any other visible highway
         which consists of or comprises a carriageway other than a made‑up carriageway, so as to render it inconvenient for the exercise
         of a public right of way; or
      
      (b)      without lawful authority or excuse, in any way wilfully obstruct the free passage along a visible highway.
      27.      A farmer must maintain any stile, gate or similar structure, other than a structure to which section 146(5) of the Highways
         Act 1980 applies, across a visible footpath or bridleway in a safe condition, and to the standard of repair required to prevent
         unreasonable interference with the rights of persons using the footpath or bridleway.
      
      28.      (1) Where a farmer has disturbed the surface of a visible footpath or bridleway (other than a field-edge path) as permitted
         under section 134 of the Highways Act 1980, he must, within the relevant period under section 134(7) of that Act, or within
         an extension of that period granted under section 134(8) of that Act
      
      (a)      so make good the surface of the path or bridleway to not less than its minimum width as to make it reasonably convenient for
         the exercise of a right of way; and
      
      (b)      so indicate the line of the path or bridleway on the ground to not less than its minimum width that it is apparent to members
         of the public wishing to use it.
      
      (2) In this paragraph, “minimum width”, in relation to a highway, has the same meaning as in Schedule 12A to the Highways
         Act 1980.
      
      29. In paragraphs 26, 27 and 28 of this Schedule 
      “bridleway”, “carriageway”, “field-edge path”, “footpath” and “made‑up carriageway” have the meanings given to them in section
         329(1) of the Highways Act 1980;
      
      “highway” has the meaning given to it in section 328 of the Highways Act 1980; and
      “visible” means visible as a route to a person with normal eyesight walking or riding along it.’
      15.      None of the implementing regulations adopted by the devolved administrations contains requirements equivalent to paragraphs
         26 to 29 of the English implementing regulations.
      
      16.      The referring court summarised the legal effects of the relevant provisions of the Highways Act 1980 as follows:
      
      ‘Disturbance of the surface of a footpath, bridleway or other highway consisting of or comprising a carriageway other than
         a made-up carriageway is an offence under section 131A. Section 134 permits the ploughing of footpaths and bridleways other
         than field-edge paths, but makes it an offence not to make it good within specified periods. Obstruction of free passage along
         any highway is an offence under section 137. By section 146(1) the owner of land is under a duty to maintain any such stile,
         gate or similar structure. Thus paragraphs 26 to 28 largely mirror these provisions of the 1980 Act, but only in relation
         to visible rights of way. …’
      
      III –  Facts and main proceedings 
      17.      The applicant is a farmer and the managing partner of a family farming partnership in Suffolk, England. He holds single payment
         scheme payment entitlements. There are public rights of way on his land within the scope of the relevant English provisions.
         
      
      18.      The applicant brought a claim before the referring court for the judicial review of paragraphs 26 to 29 of the English implementing
         regulations. He argues that the inclusion of requirements relating to the maintenance of public rights of way infringes Community
         law. First of all, public highways do not constitute agricultural land. Secondly, the English implementing regulations infringe
         the Community-law principle of equality, since none of the implementing regulations adopted by the other devolved administrations
         in the United Kingdom contains rules to that effect.
      
      19.      Thereupon the referring court made an order asking the Court of Justice for an interpretation of Regulation No 1782/2003 pursuant
         to Article 234 EC. The defendant brought an appeal against that order, which was dismissed by the Court of Appeal.
      
      IV –  Questions
      20.      By order of 11 July 2007, the Court of Appeal made a reference to the Court of Justice for a preliminary ruling on the following
         questions asked by the High Court:
      
      Where a Member State has provided for a system of devolved government, in relation to which powers are retained to the central
         State authorities to act for the whole of the territory of the Member State to ensure compliance with that Member State’s
         obligations under Community law, in relation to [Regulation No 1782/2003]:
      
      (1)      Can a Member State include requirements relating to the maintenance of visible public rights of way in its standards of good
         agricultural and environmental condition under Article 5 and Annex IV to [Regulation No 1782/2003]?
      
      (2)      Where a Member State’s internal constitutional arrangements provide that different devolved administrations shall have legislative
         competence in relation to different constituent parts of that Member State, can it give rise to impermissible discrimination
         for constituent parts to have different standards of good agricultural and environmental condition under Article 5 of and
         Annex IV to [Regulation No 1782/2003]?
      
      V –  Procedure before the Court of Justice
      21.      The order for reference was lodged at the Court Registry on 14 September 2007.
      
      22.      Written observations were submitted by the applicant in the main proceedings, the Governments of the United Kingdom and the
         Federal Republic of Germany, and by the Commission within the period laid down in Article 23 of the Statute of the Court of
         Justice.
      
      23.      At the hearing on 26 November 2008, oral argument was presented by the agents of the applicant in the main proceedings, the
         Governments of the United Kingdom, the Federal Republic of Germany, and Ireland, and by the Commission.
      
      VI –  Main arguments of the parties
      A –    The first question
      24.      The applicant in the main proceedings takes the view that the maintenance of public rights of way prescribed by the English
         implementing regulations is not among the minimum requirements for good agricultural and environmental condition which a Member
         State may define under Article 5(1) of and Annex IV to Regulation No 1782/2003. Rather, these include the retention of landscape
         features, farm structures, and avoiding the deterioration of habitats. The applicant also argues that Article 43 of Regulation
         No 1782/2003 expressly excludes paths on agricultural fields where those fields are used as forage areas and infers from that
         that rights of way could not fall within the scope of the regulation because they relate to paths. In addition, Regulation
         No 1782/2003 lays down common rules for the Community prohibiting the Member States from either ignoring the minimum requirements
         or adding to them in certain regions in their territory.
      
      25.      Even if the contested English provisions were to be regarded as environmental protection rules, they would not constitute
         minimum requirements for good agricultural and environmental condition. Because the Treaty provisions on agriculture form
         the legal basis for Regulation No 1782/2003, the environmental protection aspect of those minimum requirements cannot be construed
         as a separate provision providing for purely environmental controls. Under Article 4 of Regulation No 1782/2003, the Community
         institutions alone have the power to lay down statutory requirements in the area of the environment.
      
      26.      In the view of the United Kingdom Government, the first question must be answered in the affirmative. In this connection it
         refers to the drafting history of Regulation No 1782/2003 and in particular to the express inclusion of environmental protection
         requirements in its provisions, above all in Article 5.
      
      27.      The United Kingdom Government contends that the retention of landscape features in Annex IV covers the maintenance of public
         rights of way. A broad interpretation should be given to the concept because the concept of ‘landscape’ in Community environmental
         legislation includes features resulting from human intervention and features of historical, cultural or archaeological significance,
         and it is recognised that the landscape comprises an important component of the environment. In this respect it would not
         be conducive to achieving the environmental aims of Article 5 of Regulation No 1782/2003 to give a restrictive meaning to
         ‘landscape features’, which excluded from the scope of that expression rights of way such as footpaths and bridleways. Furthermore,
         under Annex IV those ‘standards’ are related to the ‘issue’ of guaranteeing a ‘minimum level of maintenance’ and ‘avoiding
         the deterioration of habitats’.
      
      28.      The Commission argues that the first question concerns the latitude accorded to the Member States under Article 5(1) of and
         Annex IV to Regulation No 1782/2003. In its view, the Member States enjoy considerable discretion in defining the minimum
         requirements for good agricultural and environmental condition of land, with the result that there could be significant variations
         in the different minimum requirements depending on the Member State or even depending on the region. Furthermore, many of
         the concepts contained in Annex IV, such as ‘appropriate machinery use’ or ‘landscape features’, are so general that they
         allow the Member States a wide margin of interpretation.
      
      29.      The Commission states that the concept of ‘landscape features’ lies at the heart of the main dispute. In this connection,
         a Member State is perfectly entitled to take the view that the maintenance of public rights of way is likely to protect habitats
         from deterioration, which is also an ‘issue’ under Annex IV. Similarly, a Member State may regard rights of way as ‘landscape
         features’. In addition, in its view the words ‘and environmental’ following the word ‘agricultural’ in Article 5(1) of Regulation
         No 1782/2003 give the Member States the power to define minimum requirements which serve purely environmental purposes. There
         is no contradiction between the legal basis of Regulation No 1782/2003 and the inclusion of environmental aims in its provisions,
         since Article 6 EC provides precisely for environmental protection requirements to be integrated into the definition and implementation
         of other Community policies, including agricultural policy.
      
      B –    The second question
      30.      The applicant claims that there is a difference in treatment in identical situations within the United Kingdom, which forms
         a single state. This fact increases the burden on English farmers, who, like their counterparts from other parts of the United
         Kingdom, wish to receive their payment entitlements in full. Such a difference in treatment is not objectively justified and
         thus breaches the general principle of non-discrimination which each Member State must respect, above all in the implementation
         of Community law, irrespective of its internal constitutional arrangements or the allocation of legislative powers at national
         level. Furthermore, such a difference in treatment is contrary to the Treaty provisions on agriculture.
      
      31.      According to the applicant, even though Article 5(1) of Regulation No 1782/2003 provides that a Member State may define the
         minimum requirements at national or regional level, that does not mean that the Community legislature confers a power to define
         the minimum requirements on the regional governments within the Member States. Furthermore, the expression ‘at regional level’
         refers to areas the unity of which is justified by the characteristics mentioned in the provision of the regulation, and is
         not to be construed, for example, in a political sense. Nevertheless, even though Article 5(1) leaves a Member State free
         to decide the level at which the minimum requirements are to be defined, that Member State is required to prevent any breach
         of the Community law principles of equality and non-discrimination in its territory.
      
      32.      The United Kingdom Government submits that the second question is to be answered in the negative. The case-law of the Court
         of Justice indicates that Member States are free to implement their Community obligations by measures adopted centrally or
         at regional or local level. It follows that regional implementation of Article 5(1) of Regulation No 1782/2003 in the United
         Kingdom is in principle consistent with Community law. It also follows from the fact that in its case-law the Court recognises
         the right of regional implementation enjoyed by the Member States that differences in implementation by the devolved administrations
         do not amount to discrimination contrary to Community law. Discrimination, within the meaning laid down by Community law,
         could arise only if the same lawmaker treated the same situations differently. This is a logical conclusion, since differences
         in implementation in different regions are no more discriminatory in principle than differences in implementation in different
         Member States. Furthermore, the reference in Article 5(1) of Regulation No 1782/2003 to minimum requirements being defined
         at ‘national or regional level’ makes it clear that Member States are free to implement their obligations at regional or local
         level, an option which is admittedly not dependent on an express reference.
      
      33.      Lastly, the United Kingdom Government states that such conclusions are consistent with the principle of subsidiarity and with
         the principle which underlies it, to the effect that decisions are to be taken as closely as possible to the citizen.
      
      34.      The German Government, whose observations relate solely to the second question, likewise suggests that the second question
         should be answered in the negative. In its view, different minimum requirements in constituent parts of the territory which
         are imposed by different devolved authorities do not infringe the general prohibition of discrimination under Community law,
         as there is no difference in treatment. Community law recognises the national constitutional structures and the allocation
         of competences for the implementation of Community law, in particular the competence of regional authorities. Against that
         background, the Member State as a whole is not the correct reference framework for assessing a difference in treatment, but
         the competent regional authority which implements Community law on the basis of its own competence.
      
      35.      The German Government also claims that any difference in treatment is objectively justified by the allocation of powers between
         central and devolved authorities in a Member State laid down by national law, in particular constitutional law.
      
      36.      The Commission notes that under Article 5(1) of Regulation No 1782/2003 the Member States defined minimum requirements at
         national or regional level. Accordingly, it does not appear that the Community legislature considered a uniform approach in
         each Member State to be necessary. Even though it is reasonable to suppose that the regionalisation of the minimum requirements
         for good agricultural and environmental condition of land is permissible only if it is consistent with the different aims
         of the regions, it is much more likely that the Community legislature simply left it to each Member State to choose the appropriate
         regulatory level within its political system in order to adopt the required standards.
      
      37.      With regard to the question of discrimination, the Commission takes the view that a difference in treatment can lead to such
         discrimination within the meaning of Community law only if it can be attributed to a single source. The argument put forward
         by the applicant in the main proceedings, according to which the United Kingdom is the author of the discrimination because
         it is responsible for complying with its obligation under Community law and has chosen a manner in which to implement the
         provisions in question which has caused discrimination, must be rejected. The Commission argues that none of the provisions
         of the Treaty calls into question the devolved structure of many Member States. Rather, each Member State has the right to
         determine the political level at which certain matters, including obligations under Community law, are to be regulated, provided
         that the aim of the Community legislation in question is achieved. The fact that the United Kingdom ministers retain a residual
         power to intervene in devolved areas is irrelevant to the present case.
      
      38.      In the oral procedure, Ireland essentially supported the position of the United Kingdom Government and of the Commission.
         With regard to the second question it argued that the Member States have the power in principle to decide, themselves and
         in accordance with their constitutional rules, on the manner in which Community law is implemented domestically. However,
         the measures adopted must fall within the margin of discretion accorded and implement the requirements of Community law. Differences
         in practical implementation are therefore permissible under Community law and do not constitute discrimination against individuals.
      
      39.      In addition, Ireland expresses concern that a contrary interpretation by the Court of Justice could jeopardise the cross-border
         cooperation between Ireland and the United Kingdom in matters falling within the competence of the Northern Ireland authorities,
         such as agriculture and environmental protection.
      
      VII –  Legal assessment
      A –    First question
      40.      With its first question, the referring court essentially seeks to ascertain whether the obligation imposed on farmers by the
         English implementing regulations to ensure the maintenance of public rights of way is covered by Regulation No 1782/2003.
         For that to be the case, it would have to be classified under the minimum requirements for good agricultural and environmental
         condition within the meaning of Article 5(1).
      
      41.      Another main point at issue in the present case, which must be dealt with first in my opinion, concerns the question whether
         Regulation No 1782/2003 also gives the national authorities the power to adopt environmental policy measures. Whilst the United
         Kingdom Government and the Commission argue that such a format exists, the matter is called into question in principle by
         the applicant in the main proceedings. (3)
      
      42.      The answers to these questions require an interpretation of Regulation No 1782/2003, which must first be considered in its
         overall context as a legislative measure to implement the common agricultural policy (CAP) in order to gain a better understanding
         of its regulatory purpose. It is therefore necessary first to clarify the historical and political background to its evolution.
         Consideration will then be given to the relevant provisions of the regulation and to its legal bases in primary law.
      
      1.      Environmental policy aspects in Regulation No 1782/2003 
      a)      The relationship between agriculture and environmental protection in the CAP
      43.      Agriculture has for a long time played a leading role in the European integration process. The CAP was one of the first areas
         in which the Member States handed over some of their national sovereignty to the Community and committed by far the largest
         part of the Community budget in terms of expenditure. That leading role can be explained by the particular situation in the
         post-war years and its importance for supplying the needs of the population: the CAP was originally developed to meet the
         need to ensure the supply of foodstuffs, to stabilise the markets and to guarantee an adequate standard of living for the
         agricultural population. (4)
      
      44.      Whilst the CAP was still regarded as the motor of integration in the 1960s because it led the way in terms of integration,
         it has to some extent become a burden on the Community as a result of various unfortunate developments. Thus technical advances,
         intensive production methods and the associated production of surpluses have led to increasing damage to the environment.
         In view of these new environmental risks, the Community’s efforts to reorient and reform the CAP were partly aimed at striking
         a balance between production and environmental protection. (5)
      
      45.      Particularly important on the path towards Community environmental legislation on agriculture was ‘Agenda 2000’, (6) adopted at the European Council meeting in Berlin on 26 March 1999, which set out a new European agricultural model in which
         environmental requirements were to play a greater role. It is also worth mentioning the Mid-Term Review of the Common Agricultural
         Policy presented by the Commission on 10 July 2002, (7) which was adopted by the Heads of State and Government as ‘Agenda 2000’, and in which it recommended a whole-farm approach
         where single payments per farm, which were independent of production, were conditional on compliance with statutory cross-compliance
         standards relating to the environment, food safety and quality, and animal welfare.
      
      46.      A similar approach had already been introduced by the horizontal Regulation (EC) No 1259/1999, (8) Article 3 of which imposed on the Member States the obligation to take environmental measures. (9) In that regulation, direct payments were harmonised and made conditional on environmental protection requirements. That regulation,
         like the subsequently adopted Regulation No 1782/2003 which is at issue in the present reference for a preliminary ruling,
         took soil protection aspects into consideration. However, whilst the Member States enjoyed a margin of discretion under Regulation
         No 1259/1999 as regards the application of protection requirements, all recipients of direct payments are now subject to that
         measure under Regulation No 1782/2003. (10)
      
      b)      Environmental protection requirements in Regulation No 1782/2003
      47.      It is clear from the drafting history of Regulation No 1782/2003 that it had been intended to give greater importance to environmental
         policy requirements than was envisaged in the original Commission proposal. (11) For example, the obligation imposed on the Member States by Article 5(1) to ensure that all agricultural land is maintained
         ‘in good environmental condition’ was added only subsequently in the course of the legislative procedure. The same is true
         of the obligation under Article 3 of Regulation No 1782/2003, which is worded in essentially the same terms, imposed on a
         farmer receiving direct payments, who is responsible for the implementation of the national requirements on the spot.
      
      48.      This addition, alongside the obligation to maintain agricultural land ‘in good agricultural condition’ has far-reaching consequences
         for the interpretation of Regulation No 1782/2003, as it suggests that both objectives are to be regarded as having equal
         status according to the Community legislature. 
      
      49.      It should be stressed that Article 2(c) of Regulation No 1782/2003 contains a legal definition of ‘agricultural activity’,
         which, in addition to conventional activities, expressly includes ‘maintaining the land in good agricultural and environmental
         condition as established under Article 5’.
      
      50.      Furthermore, the obligation to maintain land in good environmental condition applies without exception to ‘all agricultural
         land, especially land which is no longer used for production purposes’. The reasoning underlying that provision is given in
         the third recital in the preamble to Regulation No 1782/2003, according to which its legislative aim is to avoid the abandonment
         of agricultural land. The purpose of that provision is therefore to preserve the potential usefulness of land for agricultural
         purposes for the future. It is thus clear that the Community legislature was conscious of the close connection between environmental
         protection and agriculture.
      
      51.      A further characteristic of the abovementioned reform of the CAP, which gives central importance to environmental protection, (12) is the political conditionality expressed in Regulation No 1782/2003 where direct aid is coupled to compliance with binding
         rules, which include basic standards for the protection of the environment. This is expressly referred to in the second recital
         in the preamble. The same is true of the need emphasised in the 24th recital to make the single farm payment conditional upon
         cross-compliance with, amongst other things, environmental protection.
      
      52.      The fact that Regulation No 1782/2003 to some extent also pursues purely environmental aims and authorises the Member States
         to take appropriate measures is shown, lastly, by the need mentioned in Annex IV to ‘avoid the deterioration of habitats’
         and to ensure the ‘retention of landscape features’, which have the character of environmental rather than agricultural policy.
      
      53.      It is clear from the above that the CAP has become a Community policy which takes into account the needs of environmental
         protection. Regulation No 1782/2003 reflects this policy in so far as, despite the emphasis on agricultural aspects, it also
         pursues environmental aims. (13) Consequently, the Member States are also authorised under Article 5(1) and Annex IV to act in the interests of environmental
         protection.
      
      c)      The legal bases in primary law
      54.      This conclusion is also consistent with the requirements of primary law. The Council adopted Regulation No 1782/2003 on the
         basis of the Treaty, in particular Articles 36 EC and 37 EC and Article 299(2) EC, and thus on the basis of the provisions
         concerning agricultural policy. 
      
      55.      However, this does not preclude environmental policy issues being taken into account, especially since Article 6 EC, which
         was created as a clause imposing a general obligation by the Treaty of Amsterdam, provides that environmental protection requirements
         must be integrated into the definition and implementation of all Community policies and activities. That provision, which
         reflects the principle whereby all Community measures must satisfy the requirements of environmental protection, implies that
         a Community measure cannot be part of Community action on environmental matters merely because it takes account of those requirements. (14)
      
      56.      Through Article 6 EC, it is intended above all to ensure that the aims set out in Articles 2 EC, 3 EC and 174(1) EC are achieved. (15) It therefore cannot be ruled out that in certain situations the protection of the environment can take precedence over the
         other aims of the CAP on the basis of that Treaty provision. (16)
      
      2.      The Member States’ powers to define minimum requirements
      a)      Regulation No 1782/2003 as conferring rule-making powers
      57.      The Community legislature has rarely perceived its rule-making competences in the sphere of the CAP exhaustively in such a
         way that the Member States no longer retain any rule-making powers. In any case, the Treaty does not require the Community
         legislature to lay down definitive rules governing agricultural policy matters. The Community legislature may in principle
         also leave certain matters or individual regulatory areas for national regulation, (17) especially since the Member States play a central role in the legislative and administrative implementation of Community
         law.
      
      58.      This happened in the present case. Regulation No 1782/2003 is designed to confer rule-making powers, (18) expressly including the obligation on the Member States to adopt implementing measures. Under Article 5(1), the ‘minimum
         requirements’ are defined on the basis of the ‘framework’ set up in Annex IV, which consists of a number of ‘issues’ and ‘standards’.
         Each of those categories includes both objectives and criteria which are to be taken into consideration in the implementation
         of the requirements. Regulation No 1782/2003 therefore simply puts forward a general regulatory framework, (19) allowing the Member States a considerable margin of discretion, as the United Kingdom and the Commission rightly state. (20) The Member States are thus responsible for giving substance to the specified regulatory framework in their own legal order.
      
      59.      There is also a broad margin of discretion resulting from the use of general clauses and terms requiring interpretation, such
         as those regarding the ‘appropriateness’ of the national measures in question or the machinery to be used. In this respect,
         the arguments put forward by the United Kingdom Government and the Commission are correct.
      
      b)      The practical implementation of Regulation No 1782/2003 in England 
      60.      However, this does not relieve the Member States of the duty to adopt implementing measures which are consistent with Community
         law. Regulation No 1782/2003 constitutes the legal benchmark by which the national implementing measures are to be assessed. (21)
      
      61.      With regard to the central question whether the obligation on farmers to ensure the maintenance of public rights of way can
         be classified under the minimum requirements for good agricultural and environmental condition within the meaning of Article
         5(1), the United Kingdom Government argues that such an activity can be attributed to the standard ‘retention of landscape
         features’ mentioned in Annex IV. However, this is contested by the applicant in the main proceedings.
      
      i)      The concept of ‘landscape’ within the meaning of Regulation No 1782/2003
      62.      The question therefore arises as to the meaning of the concept of ‘landscape feature’. As Regulation No 1782/2003 does not
         itself contain any legal definition of the concept, it is subject to the Court’s power of interpretation. In this connection,
         consideration must be given to the natural use of language and the context in which the concept is generally used.
      
      63.      In addition to its meaning in art, the word ‘landscape’, which is inherent in this concept in the English language version
         (‘landscape features’), (22) appears to have a purely physiognomic and a geographical meaning. (23) In my opinion, it is necessary in the present case to examine the latter two categories.
      
      ii)    The physiognomic concept of landscape 
      64.      The physiognomic concept of landscape designates no more than ‘an expanse of terrain which is visible from a particular place
         or direction’. (24) Visible public rights of way which could be perceived from a place with one glance should be included in the concept of landscape
         under that definition.
      
      iii) The geographical concept of landscape 
      –       Topographical features 
      65.      However, the expression ‘landscape features’ in Annex IV to Regulation No 1782/2003 has certain semantic differences in the
         individual language versions. For example, the French language version refers to ‘particularités topographiques’, (25) which alludes to the geographical concept of landscape, especially since topography is a term from geography.
      
      66.      Based closely on the Greek origin of the word ‘topography’, (26) the current scientific term means, on the one hand, ‘local knowledge’, ‘description of a place’ or ‘cartography’. On the
         other hand, it is also used to describe the configuration or structure of a place. The term ‘topography’ therefore refers
         not only to the technique of representing a certain configuration of a place or the structure of the earth’s surface on a
         map, but also to the features to be shown. These features or topographical indicators can be attributable to nature and to
         human influence. (27) In addition to various buildings and infrastructures, the man-made features also include roads. (28)
      
      67.      In these circumstances, there can be no difficulty in describing public rights of way as topographical features.
      
      –       Definition of the geographical concept of landscape 
      68.      Nevertheless, the geographical concept of landscape also includes topographical features. According to one definition, this
         designates ‘a certain part of the earth’s surface which on the basis of its outward appearance and through the interaction
         of the prevailing geofactors (including human activity) has a particular character and is thereby distinguished from the surrounding
         area’. (29) According to another definition, ‘landscape’ in the geographical sense describes ‘a tract or region of land with its characteristic
         topographical features, especially as shaped or modified by (usually natural) processes and agents’. (30)
      
      69.      According to these definitions, visible public rights of way can constitute ‘landscape features’ within the meaning of Annex
         IV to Regulation No 1782/2003. The first of the abovementioned definitions describing the geographical concept of landscape
         expressly states that a part of the earth’s surface can also be influenced by human activity, such as the laying of paths.
         The second definition of landscape at least appears not to exclude completely such human influences even though it assumes
         that the definable land will be characterised primarily by natural factors.
      
      70.      The conclusion that public rights of way are covered by the concept of ‘landscape’ is further supported by the fact that human
         action in nature certainly does not always have to be regarded as harmful, but is definitely also recognised as a valuable
         factor in shaping the environment, for instance in building and forming the landscape. Consequently, a distinction is now
         drawn between ‘original natural landscape’ and ‘cultural landscape’ created by human intervention. (31)
      
      71.      As a result, landscapes, as they are now understood, may be formed by natural elements such as ‘trees, bushes, shrubs, hedges,
         flowers, grasses, water, and rocks’ and also by artificial devices like ‘decks, terraces, plazas, pavements, fences, gazebos,
         and fountains’. (32) All of this suggests that man-made features such as footpaths and field tracks are to be regarded as part of the landscape
         in the geographical sense described above. 
      
      72.      It must therefore be stated that public rights of way are also to be regarded as ‘landscape features’ within the meaning of
         Annex IV to Regulation No 1782/2003. 
      
      c)      Measure for the ‘retention of landscape features’
      73.      By imposing on farmers the obligation to maintain public rights of way, the Member State complies with its duty under Community
         law stemming from Annex IV to Regulation No 1782/2003 of ensuring that landscape features are not removed and are retained.
      
      74.      The aim of the English implementing regulations is to ensure the continued existence of such public rights of way. It contains
         rules to encourage farmers to protect public rights of way. First of all, they prohibit farmers, under threat of a penalty,
         from disturbing the surface of a visible footpath, a visible bridleway or any other visible highway. Secondly, it requires
         farmers, in the event of a contravention, to make good the damaged path or bridleway so as to make it reasonably convenient
         for the exercise of a right of way.
      
      75.      The measures provided for in the English implementing regulations are therefore perfectly capable of ensuring the retention
         of landscape features.
      
      d)      Maintenance of public rights of way as a measure to ‘ensure maintenance’ and to ‘avoid the deterioration of habitats’ within
         the meaning of Annex IV to Regulation No 1782/2003 
      
      76.      At the same time, such a measure could be classified under the ‘issue’ of ‘maintenance’ within the meaning of Annex IV to
         Regulation No 1782/2003. This includes the requirement both to ‘ensure a minimum level of maintenance’ and to ‘avoid the deterioration
         of habitats’.
      
      77.      If it is assumed, as in this Opinion, that a broad interpretation should be given to the concept of landscape, which also
         includes public rights of way as landscape features, there is nothing to prevent the measures laid down for their retention,
         such as those provided for in the English implementing regulations, being regarded as measures to ensure maintenance within
         the meaning of that provision. 
      
      78.      Apart from this, in my opinion, there is no doubt that public rights of way have a considerable importance for the preservation
         of human habitats in rural areas, especially since the importance of rights of way for human economic development was recognised
         even in Roman law. (33) First and foremost, rights of way allow farmers access to the agricultural land farmed by them.
      
      79.      Secondly, as is also clear from the order for reference, (34) public rights of way promote the mobility of inhabitants of rural areas and of visitors from other parts of the country.
         In regions with attractive landscapes, footpaths and trails can improve public access to nature and thus allow for day trips
         or longer trips, which in turn provides an opportunity for the rural and urban population to relax. (35) The function of the environment of allowing an opportunity to relax, which is enhanced by the availability of public rights
         of way, has economic benefits for the rural population, whose existence is often also reliant on tourism, because it creates
         an important value driver. 
      
      80.      At the same time, public rights of way serve to protect the environment by marking walking routes for visitors which are safer
         for flora and fauna, thereby ensuring that the environmental damage caused by people is contained. They thus help to preserve
         habitats for fauna and flora. At the same time, it is ensured that walkers and trekkers stay on the specially designated paths
         and do not walk without permission on any neighbouring fields used for agricultural purposes and cause damage to the crops
         there.
      
      81.      In this respect there is a legitimate public interest in public rights of way being regularly maintained and being protected
         against deterioration. Because the obligation to maintain public rights of way serves that purpose, it can also be classified
         as a measure to ‘avoid the deterioration of habitats’ within the meaning of Annex IV to Regulation No 1782/2003.
      
      3.      Conclusions
      82.      In summary, it may be stated that Article 5(1) of and Annex IV to Regulation No 1782/2003 confer on the Member States a broad
         margin of discretion in defining the minimum requirements for good agricultural and environmental condition of land. (36)
      
      83.      The minimum requirements within the meaning of that provision also include those which primarily serve an environmental aim.
         The maintenance of public rights of way can be classified in this category of minimum requirements, especially since, first
         of all, Annex IV states that the standards laid down include the retention, that is to say, the non‑removal of landscape features.
         As has already been shown, public rights of way constitute landscape features within the meaning of that provision. (37)
      
      84.      Secondly, a statutory obligation, as provided for by the English implementing regulations, guarantees a minimum level of maintenance
         within the meaning of Annex IV, as it both ensures a minimum level of maintenance and avoids the deterioration of habitats. (38)
      
      85.      The maintenance of public rights of way as a minimum requirement defined at regional level within the meaning of Article 5(1)
         of Regulation No 1782/2003 is thus consistent with the framework laid down in Annex IV. Furthermore, there is nothing to suggest
         that this measure would be in itself disproportionate with the aim pursued of maintaining all agricultural land in good agricultural
         and environmental condition. The use of ‘criteria which are proportionate, objective and graduated’, as prescribed in the
         second recital in the preamble to Regulation No 1782/2003, concerns a decision to be taken by the Member States in the individual
         case regarding the withdrawal of aid, the lawfulness of which must be determined, where necessary, by the competent national
         court. Lastly, it should be pointed out that according to the second recital in the preamble to that regulation such withdrawal
         is to be without prejudice to sanctions laid down under other provisions of Community or national law.
      
      86.      In this respect the English implementing regulations stay within the boundaries of the regulatory framework defined by Regulation
         No 1782/2003.
      
      87.      For that reason, the answer to the first question should be that a Member State can include requirements relating to the maintenance
         of visible public rights of way in its standards of good agricultural and environmental condition under Article 5 of and Annex
         IV to Regulation No 1782/2003.
      
      B –    The second question
      88.      With its second question, the referring court essentially seeks to ascertain whether the general principle of non-discrimination
         under Community law precludes regional differences in implementation of Community law in a Member State, which – where the
         Member State’s internal constitutional arrangements provide that different devolved administrations are to have legislative
         competence in relation to different constituent parts of that Member State – provides for constituent parts to have different
         standards of good agricultural and environmental condition under Article 5 of and Annex IV to the Regulation No 1782/2003.
      
      1.      Devolved implementation of Community law
      89.      Before I examine the breach of the general principle of non‑discrimination under Community law alleged by the applicant in
         the main proceedings, I believe that it should be pointed out that Community law does not preclude devolved implementation
         at national or at regional level. This can be explained by the demands of the CAP for devolved and differentiated implementation,
         but also by the constitutional autonomy enjoyed by the Member States, recognised in the case-law of the Court, in the allocation
         of their domestic competences.
      
      a)      Devolved and differentiated rule-making under the CAP
      90.      The main themes of the reform of the CAP introduced by ‘Agenda 2000’ include the devolution of powers from the Community to
         local level and flexible programming through a wide range of measures which can be implemented according to the specific needs
         of the Member States. (39) In other words, devolution and differentiation are now the main elements of the present CAP. (40)
      
      91.      Regulation No 1782/2003 implements this political concept by expressly authorising the Member States under Article 5(1) to
         define minimum requirements ‘at national or regional level’. This suggests that the Community legislature did not consider
         a uniform regulatory approach within each Member State to be necessary, but instead wished to leave each Member State to choose
         the appropriate regulatory level within its own political system.
      
      92.      The devolved organisation of agricultural law takes account of the fact that regional differentiation is entirely necessary.
         Thus, Article 33(2)(a) EC specifically requires that in working out the common agricultural policy and the special methods
         for its application, account is to be taken of the structural and natural disparities between the various agricultural regions.
         The margin of discretion which Regulation No 1782/2003 accords to national and regional decision‑makers for implementation
         also contributes to a differentiation corresponding to the needs of each region. (41)
      
      93.      Further considerations, such as the greater closeness of national, regional and local decision-makers to the situation and
         to the citizen, (42) the simplification of legislation and the easing of the burden on the administration, might suggest a devolved organisation
         of agricultural law provided that the Community’s aims in connection with the CAP continue to be observed.
      
      94.      A devolved organisation of agricultural law takes account not least of the increased importance of the regions within the
         European Union, which finds expression, for example, in the principle of subsidiarity being enshrined by the Treaty of Maastricht,
         the creation of the Committee of the Regions, the responsibility of the regions for the implementation of Community law and
         the possibility of representation in the Council under Article 203 EC. In addition, it takes into consideration the present
         moves towards decentralisation in the Member States, such as in the United Kingdom, largely following a similar political
         logic, (43) which suggests a convergence in developments at Community level and at national level. (44)
      
      b)      Autonomy of the Member States in the allocation of their internal powers
      95.      Lastly, the devolved implementation of Community law is consistent with the consistent case-law of the Court, (45) according to which each Member State is free to allocate powers, including legislative powers, internally as it sees fit
         and to implement Community acts which are not directly applicable by means of measures adopted by regional or local authorities,
         provided that that allocation of powers enables the Community legal measures in question to be implemented correctly. Under
         that case-law, the question as to which part of a Member State is to transpose a directive is not an issue of Community law,
         but is a matter which falls to be governed by the domestic allocation of competences. (46)
      
      96.      The reverse side of this neutrality of the Community legal order vis-à-vis the organisational structure of the Member States
         is that to the same extent as a Member State is entitled to allocate its powers internally as it sees fit and as prescribed
         by its constitutional order, it is prevented from relying on domestic circumstances in order to circumvent its obligations
         under Community law. (47)
      
      97.      It is true that the Treaty makes express provisions for a system of devolved transposition and implementation of Community
         law in the third paragraph of Article 249 EC only as regards the legal form of the directive; however, that system also applies
         in the case of the implementation of other Community legal acts, such as a regulation, which needs to be given substance by
         national legislation. (48) As has already been stated, (49) Regulation No 1782/2003 is to be classified in this category of Community legal acts.
      
      98.      Therefore it is not contrary to Community law for a Member State’s internal constitutional arrangements to provide that different
         devolved administrations shall have legislative competence in relation to different constituent parts of that Member State
         and, by virtue of the rule-making powers conferred on them, those administrations themselves define standards of good agricultural
         and environmental condition under Article 5(1) of and Annex IV to Regulation No 1782/2003.
      
      2.      The alleged breach of the principle of non-discrimination
      99.      The principle of non-discrimination under Community law, as laid down in Article 34(2) EC, on which the applicant in the main
         proceedings evidently relies, (50) is a specific expression of the general principle of equality, which is one of the fundamental principles of Community law
         and which requires that comparable situations must not be treated differently and that different situations must not be treated
         in the same way unless such treatment is objectively justified. (51)
      
      100. In accordance with the case-law of the Court, the Member States must comply with the principle stated in Article 34(2) EC
         in the implementation of Community legislation, in particular where Community rules leave Member States to choose between
         various methods of implementation or options. (52) The principle of non‑discrimination as an objective legal norm therefore applies not only to the Community legislature, at
         which it is primarily directed, but also to the Member States in so far as they act through or in execution of a Community
         regulation, for example on the basis of a power conferred on them. (53)
      
      101. The applicability of the principle of non-discrimination under Community law legally requires, first of all, the existence
         of a difference in treatment, which raises the question of the relevant reference framework. That reference framework includes
         the category of persons who may be included in the comparison. (54)
      
      a)      The relevant reference framework for assessing a difference in treatment
      i)      Mutatis mutandis application of the criteria for determining selectivity in the law on aid
      
      102. As the German Government rightly states, the reference framework for assessing a difference in treatment in a specific case
         need not necessarily be defined within the limits of a Member State, but may be restricted at one part of that territory.
      
      103. This has already been stated by the Court in relation to the law on State aid, in the judgment in Portugal v Commission, (55) which considered the question whether regionally restricted tax reductions are to be regarded as State aid ‘favouring certain
         undertakings or the production of certain goods’ within the meaning of Article 87(1) EC, that is to say, they have selective
         character. 
      
      104. As the Court found in that judgment, as regards the assessment of the condition of selectivity, which is a constituent factor
         in the concept of State aid, it is clear that Article 87(1) EC requires assessment of whether, under a particular statutory
         scheme, a State measure is such as to ‘favour certain undertakings or the production of certain goods’ in comparison with
         other undertakings which are in a legal and factual situation that is comparable in the light of the objective pursued by
         the measure in question. (56) In the opinion of the Court, such an analysis is also required in respect of a measure adopted not by the national legislature
         but by an infra-State authority, since a measure adopted by a regional authority and not the central power is likely to constitute
         aid if the conditions laid down by Article 87(1) EC are satisfied. (57)
      
      105. The Court considered whether an infra-State body enjoys a legal and factual status which makes it sufficiently autonomous
         in relation to the central government of a Member State, with the result that, by the measures it adopts, it is that body
         and not the central government which plays a fundamental role in the definition of the political and economic environment
         in which undertakings operate. (58) In such a case, it is the area in which the infra-State body responsible for the measure exercises its powers, and not the
         country as a whole, that constitutes the relevant context for the assessment of whether a measure adopted by such a body favours
         certain undertakings in comparison with others in a comparable legal and factual situation, having regard to the objective
         pursued by the measure or the legal system concerned. (59)
      
      106. I believe that it is reasonable to apply such an approach to the present situation, because the criteria employed by the Court
         are an aid in assessing the existence of a situation which, irrespective of the sector-specific terminology – ‘selectivity’
         in the case of the law on aid – ultimately constitutes no more than a difference in treatment between economic operators.
      
      107. If this approach is applied mutatis mutandis to the present situation, the relevant reference framework for assessing the discriminatory character of the provisions in
         question would have to be restricted to the constituent part of a Member State whose administrative organs enjoy their own
         rule-making powers by virtue of the applicable constitutional provisions.
      
      108. In this specific case, the reference framework would have to be defined as England as a constituent part of the United Kingdom,
         especially since, as mentioned at the beginning of this Opinion, (60) the United Kingdom Government generally acts only for England in devolved matters, in accordance with the rules on devolution
         and the Memorandum of Understanding. In accordance with the national rules, it is responsible for defining the minimum requirements
         for good agricultural and environmental condition of land pursuant to Article 5 of Regulation No 1782/2003. In this respect
         it exercises the powers of a regional government, as it were, in the sphere of agriculture, comparable to those of other regional
         governments in other constituent parts of the United Kingdom.
      
      ii)    Identification of the source of discrimination
      109. In specific cases of discrimination, the Court adopts an approach based essentially on the same considerations in order to
         determine the relevant reference framework, focusing on the source of the discrimination. Accordingly, discrimination is ruled
         out if the differences established, from which there results a difference in treatment, can be attributed to a single source.
         In the view of the Court, in such a case there is no body which is responsible for the inequality and which could, if necessary,
         restore equal treatment. (61)
      
      110. This approach has been applied primarily in situations where individuals relied on the principle, enshrined in Article 141
         EC, of equal pay for men and women. For example, in Allonby (62) the Court rejected a breach of the principle of non-discrimination in a case where a female teacher demanded from her employer,
         an agency which provided services for a college, the same pay as male employees of that college. The Court based its decision
         on the ground that the agency, as an intermediary undertaking, did not form a unit with the actual employer, the college.
         The remuneration for the services provided did not therefore come from the same financial source. (63) Because the differences in pay were not attributable to the same source, it was not possible to rely on Article 141 EC.
      
      111. Nevertheless, in my opinion, this approach may be applied to the case of national implementation or transposition of Community
         law, to which the present case relates, as it is based on the fundamental notion that mere conditions of inequality alone
         cannot be the subject of alleged discrimination. Rather, conceptually, discrimination requires that the inequality can be
         attributed to a single actor. (64) It must follow that in principle only the public authority (65) which adopts implementing and transposing measures within its sovereign territory with effect for the individuals there may
         be regarded as the source of discrimination. Any differences in treatment among those at whom a certain national measure is
         directed can be attributed only to those public authorities and can also be eliminated only by them. 
      
      112. For this reason, differences in the different national rules do not give rise to discrimination, because they cannot be attributed
         to the conduct of the same public authority. (66) Rather, the authorities are free to make rules in areas in which they are competent, with the result that a difference in
         the way a matter is regulated in two different Member States alone cannot constitute a breach of the principle of non-discrimination.
         
      
      113. This has long been recognised in the case-law of the Court. (67) Accordingly, in Van Dam en Zonen and Others (68) the Court stated for the first time that it cannot be held contrary to the principle of non‑discrimination to apply national
         legislation because other Member States allegedly apply less strict rules.
      
      114. This is immediately clear as the opposite interpretation would lead to an impairment of the legislative scope enjoyed by the
         Member States which would be difficult to justify.
      
      115. The same must apply where Member State’s internal constitutional arrangements provide that different devolved administrations
         are to have legislative competence in relation to different constituent parts of that Member State, (69) especially since, as has already been seen, not only does Community law not preclude devolved implementation or transposition
         at regional or local level, (70) but in the case of Regulation No 1782/2003 it even calls for such implementation in order to ensure a differentiated implementation
         of the CAP. (71) In such a case, only the public authority in the constituent part in question can therefore be the source of any unequal
         treatment. 
      
      b)      Conclusions
      116. This approach also leads to the conclusion that the relevant reference framework in the present case must be restricted to
         England as a constituent part of the United Kingdom. For a situation like the present case, this means that there may be unequal
         situations in the individual constituent parts of the United Kingdom, but they cannot be attributed to unequal treatment imputable
         to the same public authority, which means that a crucial criterion for the application of the principle of non-discrimination
         under Article 34(2) EC has not been met.
      
      117. Consequently, those at whom an implementing measure adopted by a regional public authority is directed cannot, in circumstances
         like those in the main proceedings, claim a breach of the principle of non-discrimination under Article 34(2) EC because individual
         constituent parts allegedly apply less strict rules.
      
      118. In the light of the foregoing, I conclude that it does not give rise to impermissible discrimination where a Member State’s
         internal constitutional arrangements provide that different devolved administrations are to have legislative competence in
         relation to different constituent parts of that Member State for constituent parts to have different standards of good agricultural
         and environmental condition under Article 5 of and Annex IV to Regulation No 1782/2003.
      
      VIII –  Conclusion
      119. In the light of the above considerations, I suggest that the Court give the following answers to the questions referred by
         the High Court of Justice of England and Wales:
      
      1.      A Member State can include requirements relating to the maintenance of visible public rights of way in its standards of good
         agricultural and environmental condition under Article 5 of and Annex IV to Council Regulation No 1782/2003.
      
      2.      It does not constitute impermissible discrimination where a Member State’s internal constitutional arrangements provide that
         different devolved administrations are to have legislative competence in relation to different constituent parts of that Member
         State for constituent parts to have different standards of good agricultural and environmental condition under Article 5 of
         and Annex IV to Regulation No 1782/2003.

      4 –	Schwartz, W., Kommentar zu EU- und EG-Vertrag (ed. Heinz Mayer), Article 32, paragraph 6, p. 17, explains that the inclusion of the agricultural sector in the common market
         was extremely controversial at first for military and political reasons. Against that background, the decision by the founding
         states of the EEC to communitarise the agricultural sector cannot be regarded highly enough. Following the traumatic experiences
         of the two world wars and the subsequent years of hunger, it was a lasting peacemaking measure of the same quality as the
         pooling of the national mining and steel industries in the European Coal and Steel Community. Priebe, R./Mögele, R., Agrarrecht, in: M. Dauses (ed.), Handbuch des EU-Wirtschaftsrechts, Vol. 1, Part G, paragraph 2, p. 3, explain that the present situation of European agricultural policy can be understood
         only against the background of the situation which existed when the Community was founded. Agriculture in Europe at the end
         of the 1950s had been influenced largely by the aim of security of supply and by a relative backwardness in terms of development
         and income compared with other economic sectors.
      
      5 –	According to Heuser, I., ‘Bodenschutz als Ziel der gemeinsamen Agrarpolitik’, Jahrbuch des Agrarrechts (ed. C. Calliess and Others), Cologne 2006, p. 187, agriculture is characterised at present increasingly by the fact that
         technical progress, intensive production methods and the associated production of surpluses are accompanied by increasing
         pressure on environmental media.
      
      6 –	See the Conclusions of the Berlin European Council of 26 March 1999 on the content of the CAP reform. They state that ‘the
         content of this reform will ensure that agriculture is multifunctional, sustainable, competitive and spread throughout Europe,
         including regions with specific problems, that it is capable of maintaining the countryside, conserving nature and making
         a key contribution to the vitality of rural life, and that it responds to consumer concerns and demands as regards food quality
         and safety, environmental protection and the safeguarding of animal welfare’.

         agricultural policy (OJ 1999 L 160, p. 113).
      
      9 –	Article 3 of Regulation No 1259/1999, which has the heading ‘Environmental protection requirements’, provides as follows
         in paragraph 1: ‘Where agricultural activity within the scope of this Regulation is concerned, Member States shall take the
         environmental measures they consider to be appropriate in view of the situation of the agricultural land used or the production
         concerned and which reflect the potential environmental effects. These measures may include: – support in return for agri-environmental
         commitments, – general mandatory environmental requirements, – specific environmental requirements constituting a condition
         for direct payments’. Schwartz, W., cited above (footnote 4), Article 34, paragraph 13, p. 31, interprets that provision as
         authorising the Member States to take appropriate measures. Adam, V., La réforme de la politique agricole commune de l’Union, Vol. I, Paris 2001, p. 266, mentions the importance of the environment-oriented political conditionality as a result of
         the inclusion of the clause cited above. The author describes it as a significant step forward in environmental policy within
         the CAP.

         of consumers, agriculture and the environment, and price stability. They also point out the greater use of environmental policy
         conditionality as a result of the adoption of Regulation No 1782/2003.
      
      14 –	See Case C‑62/88 Greece v Council [1990] ECR I‑1527, paragraph 20. Nevertheless, in the case of Regulation No 1782/2003, the emphasis of the Community’s activity
         is clearly on agriculture. 
      
      15 –	Article 6 EC refers to the Community policies and activities referred to in Article 3. Article 3 EC sets out the Community
         activities which are intended to implement the aims of the Treaty referred to in Article 2 EC, including sustainable development
         of economic activities and a high level of protection and improvement of the quality of the environment. This makes clear
         that the clause imposing a general obligation extends to all Community action. In this connection, the common policy in the
         sphere of agriculture (Article 3(e)), the common policy in the sphere of transport (Article 3(f)), the establishment and development
         of trans-European networks (Article 3(o)) and measures in the spheres of energy and tourism (Article 3(u)) have particular
         environmental relevance (see also Jahns-Böhm, J., EU-Kommentar (ed. J. Schwarze), Article 6 EC, paragraph 10, p. 277).
      
      16 –	In the view of Heuser, I., cited above (footnote 5), p. 201, the protection of the soil can take precedence over the other
         objectives of the common agricultural policy in certain situations on the basis of the environmental clause imposing a general
         obligation contained in Article 6 EC.
      
      17 –	See Priebe, R., ‘Differenzierung und Dezentralisierung in der gemeinsamen Agrarpolitik’, Tradition und Weltoffenheit des Rechts: Festschrift für Helmut Steinberger, 2002, p. 1350. See also Adam, V., cited above (footnote 9), p. 178, who points out that certain regulations in the field
         of the CAP confer rule-making powers on the Member States. This calls into question neither the exclusive competence of the
         Community nor the direct validity of a regulation. The author explains that many regulations gave the Member States a broad
         margin of discretion, which certainly does not imply a renationalisation of the CAP. This view is also shared by Priebe, R./Mögele, R.,
         cited above (footnote 4), paragraph 19. Thiele, G., Das Recht der Gemeinsamen Agrarpolitik der EG, Berlin 1997, p. 76, distinguishes between regulations which do not leave the Member States any substantive margin of discretion
         and must accordingly be directly applied and regulations which either expressly confer on the Member States the competence
         to lay down substantive provisions or do not make any definitive provisions, with the result that the Member States enjoy
         a margin of discretion.
      
      18 –	This includes regulations which must be supplemented by implementing measures adopted by the Community or the national
         legislature on the basis of an express or implicit power or obligation (see Schroeder, W., in: EUV/EGV Kommentar (ed. R. Streinz), Article 249 EC, paragraph 61; Ruffert, M., in: EUV/EGV Kommentar (ed. C. Calliess/M. Ruffert), Article 249 EC, paragraph 43, p. 2133). The Court has ruled that the Community legislature
         is not prevented from empowering a Member State to take implementing measures in a regulation (see Case C‑251/91 Teulie [1992] ECR I‑5599, paragraph 13, and Case 230/78 Eridania Zuccherifici [1979] ECR 2749, paragraph 34).
      
      19 –	See also Borghi, P., ‘Il regolamento N° 1782/2003 e le norme dell’organizzazione mondiale del commercio (OMC/WTO)’, Rivista di diritto agrario, 2005, p. 100, who considers that Annex IV merely provides a outline (consisting of the aims and the instruments which must
         be used to realise those aims), to which the Member States must adhere in defining the minimum requirements for good agricultural
         and environmental condition. A similar view is also taken by Bianchi, D., cited above (footnote 10), p. 228, in whose opinion
         the Community legislature has merely created a general regulatory framework. It has thus sought to accord the Member States
         a broad margin of discretion and at the same time transferred a considerable responsibility.
      
      20 –	Priebe, R., cited above (footnote 17), p. 1360, states that Community agricultural law is implemented predominantly by
         the Member States. In this connection, she notes that in Community agricultural legislation the Member States have been given
         scope to interpret and to draw distinctions. That scope is expressed in the form of general clauses in the legislation.
      
      21 –	As the Court stated in Eridania Zuccherifici (cited above in footnote 18, paragraph 34), the direct applicability of the measure empowering the Member State to take the
         national measures in question will mean that the national courts may ascertain whether such national measures are in accordance
         with the content of the Community regulation.

      24 –	According to a definition in the Shorter Oxford English Dictionary, 5th edition, 2002, Vol. 1, p. 1536, the concept ‘landscape’ in English means ‘an expanse of terrain or district which is
         visible from a particular place or direction; an expanse of (country) scenery’. It is consistent with the definition of the
         same concept in French (‘paysage’), which, according to Le Nouveau Petit Robert, 2007, p. 1836, is ‘étendue de terre qui s’offre à la vue’.

      33 –	According to Monier, R., Manuel élémentaire de droit romain, 6th edition, Paris 1947, p. 432, real servitudes, which include rights of way, were intended to encourage an optimal economic
         use of a property. In Roman law, a distinction was drawn within real servitudes between rural servitudes (servitutes praediorum rusticorum) and urban servitudes (servitutes praediorum urbanorum). That distinction did not depend on where the properties in question were located, but on the purpose of the servitude.
         Rural servitudes included the right of horse or foot passage (iter), a right for carriages drawn or cattle driven by man (actus) and via, which comprises the first two rights but extends also to carriage drawn by horses or other animals, and the right to conduct
         water across land (acquaeductus). Those four servitudes are probably the oldest in Roman law. The right of way (iter) also permitted riding. The right to via encompassed the right to walk, to cross by carriage and to drive cattle. The servitude of acquaeductus could also include the extraction of water. Other types of rural servitudes included the right of lead cattle to water, the
         right to draw water, the right of pasturage, and the right to search for minerals (see Mayer-Maly, T., Römisches Recht, 2nd edition, 1999, p. 97 et seq.).

         conservation during the 1940s already drew a distinction between strict nature conservation for scientific purposes and nature
         conservation and landscape protection for aesthetic and tourism purposes. As regards nature conservation and landscape protection
         for aesthetic and tourism purposes, on 18 March 1949 Parliament adopted the National Parks and Access to the Countryside Act.
         The law provided inter alia that County Councils were to open free land not used for agriculture, by agreement with its owners,
         for the population seeking an opportunity to relax, guarantee old rights of way and create new rights of way. In addition
         to setting up nature parks, ‘Areas of Outstanding Natural Beauty’ (AONB) were to be established. On account of the growing
         interest in using nature and landscape in the post-war period, the Government adopted the Countryside Act on 3 August 1968.
         It gave County Councils the opportunity to create Country Parks for the population seeking an opportunity to relax, the costs
         for which would be largely reimbursed by the State. The Countryside and Rights of Way Act 2000, which applies at present,
         makes provision for public access to the countryside; according to the preamble, the Act also pursues environmental policy
         aims such as ‘conserving an area’s natural beauty‘, ‘nature conservation‘ and ‘the protection of wildlife’.

         in the EU-15 is highly diverse in its natural resources, its farming methods, its competitiveness and income level, and also
         its traditions. In the Union, diversity is one of the strengths of European agriculture, contributing to its character and
         quality. However, in order to derive greater benefit from this, that diversity requires the appropriate consequences to be
         drawn for agricultural policy – the present method of operation and management of the CAP were devised for a Community of
         6 and have not really changed since then. It will not meet the needs of a Union of 15 which is preparing for the accession
         of new Member States. It has become far too complex and bureaucratic, and sometimes even almost impossible for farmers to
         understand. A new, more decentralised model has, therefore, to be developed which grants the Member States greater freedom to regulate certain matters themselves,
         taking better account of the respective sectors or the respective local conditions, COM(1998) 158 final, p. 3.

      41 –	Boch, C., ‘Devolution and Community law’, A true European, 2005, p. 54, points out that devolved decision-makers increasingly have to deal with matters in which the Community legislature
         lays down the main policy objectives. This also applies to situations in which the devolved decision-makers are accorded a
         margin of discretion. Nevertheless, that margin of discretion enables them to take account of regional or local differences.
      
      42 –	This is at least consistent with the notion of subsidiarity, without thereby affirming that the second paragraph of Article
         5 EC is applicable, especially since under that provision the principle of subsidiarity does not apply in areas which do not
         fall within the exclusive competence of the Community. The extent to which the Community has exclusive competence in agriculture
         is disputed in legal literature (see Schwartz, W., cited above (footnote 4), Article 37, paragraph 7, p. 38). Even assuming
         competing competences between the Community and the Member States (see judgment in Case C-158/89 Weingut Dietz-Matti [1990] ECR I‑2013]), the intensity of regulation which exists in the agricultural sector and is constantly increasing and
         the fact that almost all general provisions in that field are made by regulation have not really left the individual Member
         States any margin of discretion. On the other hand, as Lenaerts, K./Van Nuffel, P., Constitutional Law of the European Union, 2nd edition, London 2005, paragraph 5‑029, p. 102, rightly explain, the notion of subsidiarity as a political principle
         is older than the provision laid down in the second paragraph of Article 5 EC and therefore had an influence on several Community
         policy areas, including the CAP, before it was enshrined in the Treaty.

         is known as devolution, essentially seeks to modernise the state’s administration and bring citizens closer to the place when
         the important decisions are taken. These developments are also intended to ensure that the particular features of each region
         are taken into consideration.

         process in the European Union, which enhances the autonomy of the large regional authorities. Birkinshaw, P., ‘Devolution
         in the United Kingdom: Processes, problems and consequences for the UK constitution’, L’Europa tra federalismo e regionalismo, Milan 2003, p. 67, stresses that devolution in the United Kingdom was carried through at a time when the regions within
         the European Union were taking on greater importance.

         26/62 Van Gend and Loos [1963] ECR 1 and Case 6/64 Costa v ENEL [1964] ECR 585. International law governs only relations between States, without interfering in their internal affairs. In
         this respect, based on the principle of the sovereignty of States, has no bearing on the law governing the organisation of
         the State. Consequently, it is consistent with a principle of customary international law, which was codified in Article 27
         of the Vienna Convention on the Law of Treaties, that a party may not invoke the provisions of its internal law as justification
         for its failure to perform a treaty. As Boch, C., cited above (footnote 41), p. 54, rightly states, at a formal level the
         EU/EC treaties constitute international agreements which are binding on the Member States. The fact that the Member States
         are the contracting parties means that, from a Union prospective, the national constitutional arrangement of each Member State
         must be irrelevant. Internal matters are of no concern to the Union, which remains in the main ‘blind’ towards the internal
         distribution of powers.

      64 –	See Plötscher, S., Der Begriff der Diskriminierung im Europäischen Gemeinschaftsrecht, Berlin 2003, p. 48, in whose view discrimination requires that the inequality is attributable to one actor. Mere conditions
         of inequality alone cannot be the subject of alleged discrimination. Provided it cannot be established that the unequal conditions
         existing within a category of objects under comparison (persons, goods etc.), e.g. different competitive positions, are attributable
         to the conduct of a legal entity, there cannot be any question of discrimination. Discrimination therefore requires the inequality
         to be attributable to one organ adopting a measure. In the view of Zerr, H., Der Begriff der Diskriminierung im Vertrag über die Europäische Gemeinschaft für Kohle und Stahl, Heidelberg 1961, p. 4, it is necessary, if there is unequal treatment, for there to be at least two expressions of behaviour
         by a single person.
      
      65 –	Von Bogdandy, A., in: Grabitz/Hilf, Das Recht der Europäischen Union, Munich 2008, Vol. I, Article 12, paragraph 9, points out that, according to the prevailing view, discrimination is possible
         only if the two situations under comparison were regulated by the same public authority. A breach of the principle of non‑discrimination
         is therefore ruled out in the case of differences in treatment stemming from the coincidence of rules adopted by different
         public authorities, in particular by the Union and a Member State. The opposite interpretation would lead to an impairment
         of the legislative scope enjoyed by the Member States which would be difficult to justify.

         State provide for implementation or transposition by devolved institutions, there is nothing to prevent those institutions
         exercising their discretion independently of one another. In connection with devolution in the United Kingdom, the author
         takes the view that the regions of that Member State are perfectly entitled to comply with Community law obligations in different
         ways, which has already happened under the CAP.
