      3.  Article 2 of Directive 73/23 provides that: 
      1.  The Member States shall take all appropriate measures to ensure that electrical equipment may be placed on the market only
      if, having been constructed in accordance with good engineering practice in safety matters in force in the Community, it does
      not endanger the safety of persons, domestic animals or property when properly installed and maintained and used in applications
      for which it was made.
      
      2.  The principal elements of the safety objectives referred to in paragraph 1 are listed in Annex I.
      
      
      4.  Article 3 of that directive provides that:The Member States shall take all appropriate measures to ensure that if electrical equipment is of such a nature as to comply
      with the provisions of Article 2, subject to the conditions laid down in Articles 5, 6, 7 and 8, the free movement thereof
      within the Community shall not be impeded for reasons of safety.
      
      5.  Article 8(1) of Directive 73/23 as amended by Directive 93/68  
      
         			(5)
         		 reads as follows:1. Before being placed on the market, the electrical equipment referred to in Article 1 must have affixed to it the CE marking
      provided for in Article 10 attesting to its conformity to the provisions of this directive, including the conformity assessment
      procedure described in Annex IV.
       2. Directive 89/336
      
      6.  Article 1(1) of Directive 89/336 defines  
      apparatus as all electrical and electronic appliances together with equipment and installations containing electrical and/or electronic
      components.

      be affected by such disturbance.
      
      8.  Article 3 of that directive, as amended by Directive 93/68, provides that:Member States shall take all appropriate measures to ensure that the apparatus referred to in Article 2 may be placed on the
      market or taken into service only if it bears the CE marking provided for in Article 10 indicating its conformity to all the
      provisions of this directive, including the conformity assessment procedures laid down in Article 10, when it is properly
      installed and maintained and when it is used for the purposes for which it is intended.
      
      9.  Article 5 of that directive reads as follows:Member States shall not impede for reasons relating to electromagnetic compatibility the placing on the market and the taking
      into service on their territory of apparatus covered by this directive which satisfies the requirements thereof.
       3. Directive 1999/5
      
      10.  Article 1 of Directive 1999/5 establishes a regulatory framework for the placing on the market, free movement and putting
      into service in the Community of radio equipment and telecommunications terminal equipment.
      
      11.  Article 2(c) of that directive defines  
      radio equipment as a product, or relevant component thereof, capable of communication by means of the emission and/or reception of radio
      waves utilising the spectrum allocated to terrestrial/space radiocommunication.
      
      12.  Article 3 provides that certain essential requirements are applicable to all apparatus. In addition, it stipulates that radio
      equipment must be so constructed that it effectively uses the spectrum allocated to communication so as to avoid harmful interference.
      
      13.  Article 5 of that directive provides that, where apparatus meets the harmonised standards, compliance with those of the essential
      requirements referred to in Article 3 is to be presumed. 
      
      14.  Article 6(1) of Directive 1999/5 reads as follows:Member States shall ensure that apparatus is placed on the market only if it complies with the appropriate essential requirements
      identified in Article 3 and the other relevant provisions of this directive when it is properly installed and maintained and
      used for its intended purpose. It shall not be subject to further national provisions in respect of placing on the market.
      
      15.  Article 7(1) provides that:1. Member States shall allow the putting into service of apparatus for its intended purpose where it complies with the appropriate
      essential requirements identified in Article 3 and the other relevant provisions of this directive.
      
      16.  Article 8(1) reads as follows:Member States shall not prohibit, restrict or impede the placing on the market and putting into service in their territory
      of apparatus bearing the CE marking referred to in Annex VII, which indicates its conformity with all provisions of this directive,
      including the conformity assessment procedures set out in Chapter II. This shall be without prejudice to Articles 6(4), 7(2)
      and 9(5).
      
      17.  Under the first paragraph of Article 19(1) of that directive:Member States shall not later than 7 April 2000 adopt and publish the laws, regulations and administrative provisions necessary
      to comply with this directive. They shall forthwith inform the Commission thereof. They shall apply these provisions as from
      8 April 2000.
      
      
      
      B ─
       National law
      
      18.  Article 12 of the Law of 10 April 1990 on caretaking firms, security firms and internal caretaking services  
      
         			(6)
         		 (hereinafter the  
      Law of 10 April 1990) provides that the alarm systems and networks referred to in Article 1(4) and their components may be marketed or otherwise
      made available to users only after prior approval has been granted under a procedure to be laid down by the King. The King
      also determines the conditions governing installation, maintenance and use of the alarm systems and networks referred to in
      Article 1(4) and their components. 
      
      19.  Article 12 was replaced following the Law of 9 June 1999,  
      
         			(7)
         		 which entered into force on 1 November 1999. The new Article 12 reads as follows: The alarm systems and networks referred to in Article 1(4) and their components may be marketed or otherwise made available
      to users only after prior approval has been granted under a procedure to be laid down by the King.The alarm systems and networks referred to in Article 1(4) and their components, marketed or otherwise made available to users,
      must always conform to the prototype approved under the procedure to be laid down by the King referred to in paragraph 1.The King shall also determine the conditions governing installation, maintenance and use of the alarm systems and networks
      referred to in Article 1(4) and their components.
      
      20.  As provided for in the first paragraph of Article 19(1) of the Law of 10 April 1990, an administrative fine of between BEF
      1 000 and 1 000 000 may be imposed upon any natural or legal person who infringes that law or its implementing decrees, except
      for the infringements referred to in Article 18.
      
      21.  On the basis of the first paragraph of Article 12 of the Law of 10 April 1990, a royal decree laying down the procedure for
      approving the alarm systems and networks referred to in the Law of 10 April 1990 on caretaking firms, security firms and internal
      caretaking services  
      
         			(8)
         		 was adopted on 23 April 1999 (hereinafter  
      the Royal Decree of 23 April 1999). The royal decree entered into force on 19 June 1999. 
      
      22.  Under Article 1(2) of the Royal Decree of 23 April 1999,  
      equipment means  
      the alarm systems and networks and their components intended to prevent or record crimes against persons or property.
      
      23.  Article 2 of that royal decree reads as follows: 
      1.  No manufacturer, importer, wholesaler or any other natural or legal person may market equipment or make it available to users
      in Belgium if it has not been previously approved by a committee established for that purpose (the  
      equipment committee).
      
      2.  For each equipment prototype approved, the equipment committee shall issue a certificate of approval, using the model set
      out in Annex 1 of this decree, which certificate shall be retained by the applicant. The applicant shall provide a conformity label, at his own expense, for equipment which conforms to the prototype and which
      is marketed or made available to users....The departments responsible for overseeing the implementation of the abovementioned Law of 10 April 1990 and its implementing
      decrees may ask one of the bodies referred to in Article 4(1) of this decree to check the conformity of equipment which is
      marketed or made available to users. That body shall forward a report on those checks to the equipment committee, which, on
      the basis of that report, shall state whether or not the equipment conforms.The costs of those checks shall be borne by the person who requested the approval tests leading to approval.
      
      
      24.  Article 4(1) of the Royal Decree of 23 April 1999 provides that: After the equipment committee has delivered its opinion, the Interior Minister shall draw up a list of bodies specialising
      in carrying out the tests which precede approval of the equipment, if appropriate, or verifying the reports referred to in
      Article 9 of this decree. Requests for approval of equipment shall be made directly to one of those bodies. Only those bodies shall be competent to
      carry out the tests.
      
      25.  According to Article 5 of the Royal Decree:  Before beginning the tests proper, the laboratories shall examine the equipment.That examination shall consist of:1. identifying the equipment;2. checking electrical circuits against the documents submitted by the manufacturer;3. checking the minimum required functions, as described in Annex 3 to this decree....
      
      26.  Article 6 provides that: The tests carried out on the equipment shall concern:1. functional adequacy;2. mechanical aspects; 3. mechanical and/or electronic reliability;4. sensitivity to false alarms;5. protection against fraud or attempts to neutralise the equipment; For that purpose, equipment shall be subjected to the tests listed in Annexes 3 and 5 to this decree. Those tests shall be
      applicable to the different types of component.Equipment using radio channels shall also be subjected to the tests referred to in Annex 6.
      
      27.  Article 7 of the decree reads as follows: The laboratories of the bodies referred to in Article 4(1) shall check whether the equipment presented meets the requirements
      listed in Annex 7.To that end, the applicant must provide the abovementioned laboratories with all the documents relevant to that examination.
      
      28.  Article 9 of the royal decree provides that:For the purposes of approval of the alarm systems and networks imported from other Member States of the European Union and
      from Member States of the European Free Trade Association, contracting parties to the Agreement on the European Economic Area,
      certificates and reports of tests drawn up by an approved or accredited body in those States shall be accepted in so far as
      they attest to the conformity of those systems and networks to technical standards or regulations which ensure a level of
      protection equivalent to that which is provided by this decree.
      
      29.  Article 11 of the Royal Decree of 23 April 1999 provides that: Approvals shall be valid for a period of three years and may be extended, each time for the same period, on application. Applications
      for extension shall be submitted to one of the bodies referred to in Article 4(1) and shall be processed and examined in accordance
      with the abovementioned Articles 4 to 9.Equipment to which alterations are made must be re-submitted to one of the bodies referred to in Article 4(1), which shall
      decide whether supplementary tests are necessary.
      
      30.  Article 12 provides that the administration and operation costs involved in the application procedure, the tests and the conformity
      check are to be borne by the applicant.
       III ─ Main proceedings and course of the procedure
      
      
      
      A ─
       Main proceedings
      
      31.  ATRAL, a public limited company incorporated under French law, having its registered office in France (hereinafter  
      ATRAL), manufactures and markets alarm systems and networks using radio transmission (commonly referred to as  
      wireless alarm systems). Since 1996, ATRAL has been marketing its alarm systems and networks in Belgium, primarily via large-scale
      retailers.
      
      32.  Until the Royal Decree of 23 April 1999 entered into force, the sale of ATRAL's products was not regulated, as the regulations
      then in force (the Royal Decree of 31 March 1994 laying down the procedure for approval of the alarm systems and networks
      referred to in the Law of 10 April 1990 on caretaking firms, security firms and internal caretaking services) applied only
      to  
      wired-link alarm systems and networks.
      
      33.  Since the entry into force of the royal decree, which now applies also to  
      wireless alarm systems and networks, ATRAL has been unable to market its products without first obtaining approval for them from the
       
      equipment committee.
      
      34.  On 16 August 1999, ATRAL asked the Conseil d'État to annul the Royal Decree of 23 April 1999.
      
      35.  In addition, on 31 August 1999, ATRAL lodged a complaint with the European Commission alleging that the import of alarm systems
      and networks into Belgium was being obstructed. As a result of that complaint, the Commission gave the Kingdom of Belgium
      formal notice to submit comments on the matter. Those proceedings are still pending. ATRAL also brought an action before the
      Tribunal de Première Instance de Bruxelles (Court of First Instance, Brussels) with a view to obtaining an order prohibiting
      the Belgian State from making the sale of its products in Belgium subject to prior approval. Those proceedings are still pending.
      
      36.  ATRAL argued before the Conseil d'État that the Royal Decree of 23 April 1999 infringes Article 28 EC. It contended that,
      for the most part, the royal decree regulates areas harmonised at Community level by Directive 73/23, Directive 89/336 and
      Directive 1999/5. ATRAL considers that the Belgian legislature should not therefore have adopted rules more restrictive than
      those contained in the harmonised legislation. ATRAL infers from this that the Belgian State cannot impose precautionary checks
      to verify the conformity of alarm systems and networks. The directives authorise only subsequent checks. Conformity with the
      essential technical and qualitative requirements laid down by those directives is attested by the CE marking, to be affixed
      by the undertaking where the products in question satisfy a conformity assessment procedure defined in the relevant articles
      of, and annexes to, Directives 73/23, 89/336 and 1999/5.
      
      37.  ATRAL also argued that the Belgian State could regulate only the non-harmonised area of the field in question, and even then
      must do so in compliance with the Treaty and in particular Article 28 EC. In that respect, ATRAL takes the view that the Royal
      Decree of 23 April 1999, in particular Article 9 thereof, is not compatible with the principle of mutual recognition, under
      which any product imported from a Member State must be admitted into the territory of the importing Member State if it has
      been lawfully manufactured and marketed in the State of origin, even if that product was manufactured in accordance with technical
      or qualitative specifications different from those applicable to products from the importing State, unless overriding reasons
      or imperative requirements in the public interest are relied on, and even then the principles of necessity and proportionality
      must be observed. Article 9 of the contested royal decree concerns only mutual recognition of the tests required for prior
      approval and does not therefore relate to mutual recognition of the products themselves. Such limited mutual recognition,
      it contends, is permissible only if it is justified by an essential requirement not already taken into account by the harmonised
      legislation and if it is demonstrated that that restriction on trade between Member States is necessary and proportionate,
      which it is not. As regards any essential requirements not yet the subject of harmonised legislation at Community level, regulations
      which restrict trade must, if they are to comply with Articles 28 and 30 EC, be justified by an overriding reason or an imperative
      requirement in the public interest and must be proportionate to the objectives pursued. ATRAL considers that, in the present
      case, the Belgian State has failed to show precisely which essential requirements in the interests of consumer protection,
      other than those already taken into account by the aforementioned directives, justify a system of prior approval such as that
      provided for in the contested decree. Public policy, essentially the prevention of  
      false alarms, which was a further ground raised by the Belgian State, likewise does not provide justification. The Belgian State is, moreover,
      the only State to have introduced such a system.
      
      38.  The Belgian State disputes first of all the assertion that Directives 73/23/EEC and 89/336/EEC relate to the subject-matter
      regulated by the Royal Decree of 23 April 1999. As far as Directive 1999/5 is concerned, the Belgian State considers that
      it is irrelevant in the present case on the ground that, on the date which the Conseil d'État must take into account for the
      purposes of assessing the validity of the contested decree, that is 23 April 1999, the period given to Member States to transpose
      that directive into their national law had not yet expired. It is therefore incumbent on the Conseil d'État to disregard the
      directive in assessing the legality of the contested decree, including its compatibility with Community law. Such compatibility
      must be assessed only in the light of Articles 28 to 30 EC. A derogation from the general prohibition on measures having equivalent
      effect is justified in the present case on grounds of both consumer protection and public policy. The derogation is necessary
      and proportionate to the objectives pursued.
      
      39.  Before giving judgment on the action brought by ATRAL, the Conseil d'État considered it necessary to refer a number of questions
      to the Court of Justice for a preliminary ruling.
      
      
      
      B ─
       The questions referred
      
      40.  By order of 8 January 2002, the Conseil d'État referred the following questions to the Court:  
      (1) Should Council Directive 73/23/EEC of 19 February 1973 on the harmonisation of the laws of Member States relating to electrical
      equipment designed for use within certain voltage limits, Council Directive 89/336/EEC of 3 May 1989 on the approximation
      of the laws of the Member States relating to electromagnetic compatibility and Directive 1999/5/EC of 9 March 1999 of the
      European Parliament and of the Council on radio equipment and telecommunications terminal equipment and the mutual recognition
      of their conformity be interpreted: 
      (a) as applicable to alarm systems and networks, in particular to products of that type which use radio transmission, commonly
      known as wireless alarm systems, 
      
      (b) and, if the answer thereto is in the affirmative, as producing sufficiently significant harmonisation in that field that national
      provisions governing the same field, such as Article 12 of the Law of 10 April 1990 on caretaking firms, security firms and
      internal caretaking services and the Royal Decree of 23 April 1999 laying down the procedure for approving the alarm systems
      and networks referred to in the Law of 10 April 1990, must necessarily conform to them? 
      
      
      (2) In the event that the reply to the first question is in the affirmative:
      
      
      
            ─
               Should Article 3 of Council Directive 73/23/EEC of 19 February 1973, Article 5 of Council Directive 89/336/EEC of 3 May 1989
               and Article 6(1) of Directive 1999/5/EC of the European Parliament and of the Council of 9 March 1999 be interpreted as prohibiting
               national provisions which, as do Article 12 of the Law of 10 April 1990 and the Royal Decree of 23 April 1999, make the placing
               on the market in a Member State of all alarm systems and networks lawfully produced and/or marketed in another Member State
               ... subject to a prior authorisation procedure relating to components of those alarm systems and networks which satisfy the
               requirements of the directives referred to? 
             
      
      
      
      
            ─
               Should Council Directive 73/23/EEC of 19 February 1973, Council Directive 89/336/EEC of 3 May 1989 and Directive 1999/5/EC
               of the European Parliament and of the Council of 9 March 1999 be interpreted as establishing the essential requirements, in
               relation to alarm systems and networks, for electrical safety, electromagnetic compatibility and radio equipment and, consequently,
               as precluding national provisions, such as the Royal Decree of 23 April 1999, which make the placing on the market in Belgium
               of all alarm systems and networks subject to requirements other than those established in those directives? 
             
      
      
      
      
            ─
               Should Articles 28 to 30 EC be interpreted as meaning that the prohibition on quantitative restrictions on imports and on
               measures having equivalent effect applies to national provisions, such as the Royal Decree of 23 April 1999, which require
               components of alarm systems and networks not covered by Community harmonisation measures to undergo the same tests in an authorised
               laboratory as equipment placed on the market for the first time? 
             
      
      
      
      
            ─
               Should Articles 28 to 30 EC be interpreted as meaning that the prohibition on quantitative restrictions on imports and on
               measures having equivalent effect allows a Member State to adopt national provisions, such as the Royal Decree of 23 April
               1999, which makes the placing on the market in a Member State of all alarm systems and networks lawfully manufactured and/or
               marketed in another Member State subject to prior approval and to tests and specific technical requirements, merely relying
               in the abstract on an overriding reason or a compelling requirement, such as consumer protection and/or public policy, which
               the State considers the Community harmonisation measures do not take into account or, in other words, without specifically
               demonstrating either that the overriding reason or compelling requirement relied on actually exists or that the Community
               harmonisation measures do not already take that overriding reason or compelling requirement into account or that the restrictive
               measure is proportionate to the aim pursued? 
             
      
      
      (3) In the event that the reply to the first question is negative:
      
      
      
            ─
               Should Articles 28 to 30 EC be interpreted as meaning that the prohibition on quantitative restrictions on imports and on
               measures having equivalent effect applies to national provisions, such as Article 9 of the Royal Decree of 23 April 1999,
               which, rather than applying the requirement of mutual recognition to the alarm systems and networks themselves, confine the
               requirement of mutual recognition to the tests which alarm systems and networks lawfully manufactured and/or marketed in another
               Member State must undergo in order to obtain authorisation to be placed on the market of a Member State?

      C ─
       Proceedings before the Court
      
      41.  In the proceedings before the Court, written observations were submitted by ATRAL, the Belgian Government and the Commission.
      They expanded on their views at the hearing of 3 October 2002. The French Government also put forward its views at that hearing.
       IV ─ Assessment
      
      
      
      A ─
      The first set of questions ─ Question 1(a) and 1(b) 
      42.  The first set of questions relates to Directives 73/23, 89/336 and 1999/5. By those questions, the national court is in essence
      asking whether the three directives apply to alarm systems and networks, in particular wireless alarm systems, and, if so,
      whether the degree of harmonisation is such that national provisions governing that field must necessarily conform to them.
      
      43.  There is in essence no difference of opinion on those questions between the parties which have submitted written or oral observations.
      They all agree that the three directives apply to the products at issue and that the degree of harmonisation is such that
      national regulations must conform to them.
      
      44.  I concur with that view. Alarm systems and networks consist of various components which fall within the scope of the three
      directives. Thus, Directive 73/23 applies to electrical equipment within the voltage limits laid down in the directive. The
      components of systems and networks which operate at a low voltage are therefore covered by that directive. Moreover, Directive
      89/336 applies to any apparatus which is liable to cause electromagnetic disturbance or the performance of which is liable
      to be affected by such disturbances. Those systems and networks fall within the definition of apparatus set out in Article
      1 of that directive. Finally, Directive 1999/5 establishes a regulatory framework for the placing on the market, free movement
      and putting into service in the Community of radio equipment and telecommunications terminal equipment. Wireless alarm systems
      and networks also fall within the definition of radio equipment as set out in Article 2(c) of that directive.
      
      45.  It follows that the three directives apply to alarm systems and networks which use radio transmission. They concern any aspects
      of the performance of such apparatus, or its components, which involve the use of low voltage current, the prevention of electromagnetic
      disturbance and the emission and reception of radio signals.
      
      46.  The Commission, the French Government and the parties to the main proceedings agree that each of the three directives referred
      to is intended to achieve complete harmonisation within the field to which it applies. I share that view, which follows without
      any doubt from the letter and spirit of those directives. The Belgian legislation and regulations must therefore comply with
      the directives in full where they extend to the matters covered by the directives. I need hardly add that that legislation
      and those regulations cannot impose on economic transactions relating to the apparatus in question restrictions which go beyond
      what the abovementioned directives expressly allow.
      
      47.  Nevertheless, the directives do not govern all aspects of the performance of alarm systems and networks. For example, depending
      on how it is to be used, such apparatus must comply with certain requirements as regards its functionality, such as reliability,
      sensitivity to false alarms, and durability. These points are addressed in the second question.
      
      
      
      
      
      B ─
      Second set of questions referred (Question 2) 
      48.  Question 2 is made up of four questions. The first two relate to the components of alarm systems and networks to which Directives
      73/23, 98/336 and 1999/5 apply. I shall address those two questions together below. The questions on the interpretation of
      Articles 28 and 30 EC will then each be addressed in turn.
      
      49.  Article 3 of Directive 73/23, Article 5 of Directive 89/336 and Articles 6 and 8 of Directive 1999/5 guarantee the free movement
      of goods, both apparatus and its components, which satisfy the requirements laid down therein.
      
      50.  As the Commission explained in greater detail in its written observations, the harmonisation achieved by those directives
      confers a presumption of conformity on apparatus bearing the CE marking. That marking indicates the conformity of the product
      in question to all the provisions of the relevant directives, including the procedures for assessment of conformity to standard,
      as provided for in the directives. The directives contain a number of derogations from that basic rule but these are of no
      relevance in this case.
      
      51.  The rules described above enable manufacturers to place products bearing the CE marking on the market without first having
      to use an approved or accredited approval body. Furthermore, in the case of products bearing the CE marking, there is no need
      to produce test certificates or reports from approved or accredited approval bodies.
      
      52.  It follows that Article 12 of the Belgian Law of 10 April 1990, as amended by the Law of 9 June 1999, infringes the directive.
      After all, under that provision, products bearing the CE marking or otherwise shown to conform to the directives are subject
      to a prior approval procedure before they may be marketed in Belgium. 
      
         			(9)
         		 That procedure also requires that the products in question undergo tests and checks.
      
      53.  Article 9 of the Royal Decree of 23 April 1999 also infringes the rules contained in the directives. That provision states
      that, for the purposes of approval of the alarm systems and networks imported from other Member States of the European Union
      and Member States of the European Free Trade Association, contracting parties to the Agreement on the European Economic Area,
       
      test certificates and reports drawn up by an approved or accredited body in those States shall be accepted in so far as they
      attest to the conformity of those systems and networks to technical standards or regulations which ensure a level of protection
      equivalent to that which is provided by this decree. The directives, on the other hand, provide for a presumption of conformity in the case of products bearing the CE marking
      or otherwise shown to conform to the directives. Article 9 of the royal decree is clearly incompatible with those rules.
      
      54.  More generally, it follows from the Community directives at issue here that the Member States cannot make the marketing of
      components and finished products subject to requirements other than those which are expressly provided for in those directives
      in the fields which they cover. National provisions laid down by law or administrative action which have the aim or effect
      of imposing such requirements are therefore incompatible with those directives.
      
      55.  In my view, Questions 2(a) and (b) should be answered to that effect.
      
      56.  Questions 2(c) and (d) relate to the components or characteristics of alarm systems and networks which are not covered by
      Community harmonisation measures.
      
      57.  Question 2(c) relates to the requirement under the Belgian legislation that the components of alarm systems and networks which
      are not covered by Community harmonisation measures undergo the same tests in an approved laboratory as equipment placed on
      the market for the first time.
      
      58.  In the absence of Community rules, it is open to the Member States to retain or adopt national measures provided that they
      are compatible with the free movement of goods. This means that quantitative restrictions on imports and any measures having
      equivalent effect are prohibited. It is settled case-law of the Court that all trading rules enacted by Member States which
      are capable of hindering, directly or indirectly, actually or potentially, intra-Community trade are to be regarded as measures
      having an effect equivalent to quantitative restrictions.  
      
         			(10)
         		 Pursuant to Article 30 EC, Article 28 EC does not preclude prohibitions or restrictions on imports which can be justified
      on the grounds set out in that article provided that such prohibitions or restrictions do not constitute a means of arbitrary
      discrimination or a disguised restriction on trade between Member States. Moreover, obstacles to movement within the Community
      resulting from disparities between the national laws must be accepted in so far as they are necessary in order to satisfy
      mandatory requirements.  
      
         			(11)
         		 Nevertheless, whether it is covered by the situations referred to in Article 30 EC or whether it is based on imperative requirements
      in the public interest established by case-law, national legislation which derogates from Article 28 EC can be justified only
      if it is consistent with the principles of necessity and proportionality.  
      
         			(12)
         		
      59.  Firstly, I would point out, as the Commission has, that a national measure which imposes tests which are the same as those
      already carried out in the country of origin is a measure having equivalent effect within the meaning of Article 28 EC even
      if the field in question is not harmonised.
      
      60.  The same applies to a provision which, for the purposes of approval of alarm systems and networks imported from another Member
      State, accepts test certificates and reports drawn up by an approved or accredited body in that Member State only in so far
      as they attest to the conformity of those systems and networks to technical standards and regulations guaranteeing the same
      level of protection as in the country of importation. After all, a consequence of such an approval system is that a producer
      who wishes to export his systems and networks to Belgium must have that equipment tested and approved in his own country in
      order to satisfy the requirements of the Belgian legislature, even if the equipment can be marketed in his own country without
      the intervention of an approval body.
      
      61.  A condition requiring conformity to the same technical standards and level of protection as those obtaining in the country
      of importation has by definition the consequence of obliging producers from other Member States to adapt their products to
      the specific requirements of that country. Such a technical obstacle to trade by definition constitutes an infringement of
      Article 28 EC. It is in breach of the principle of mutual recognition.
      
      62.  As I stated in point 58, such a provision can be justified on one of the public interest grounds defined in Article 30 EC
      or on the basis of one of the imperative requirements in the public interest established by case-law. The provision must also
      be necessary and proportionate.
      
      63.  The Commission has rightly pointed out that, even if an obstacle to the freedom of movement could be justified on the grounds
      relied on by the Belgian Government, it is for the national court to assess whether the requirement of a prior approval procedure
      is necessary to attain the objective pursued and whether it is proportionate. The necessity and proportionality of the test
      certificate or report required under Article 9 of the royal decree must also be assessed in this context. As the Commission
      also points out, the national court does not ask whether the grounds of justification relied on by the Belgian Government
      satisfy the conditions laid down by Article 30 EC or by case-law. The fourth question is, in essence, concerned exclusively
      with the burden of proof.
      
      64.  The question is whether it is sufficient for a Member State to rely on an abstract reference to an imperative requirement
      or an overriding reason, such as consumer protection or public policy, which the State considers is not, or not sufficiently,
      taken into account in Community harmonisation measures, or whether a Member State is in fact required to provide tangible
      evidence that the imperative requirement or overriding reason relied on actually exists, that it has not already been taken
      into account by the Community harmonisation measures, and that the restrictive measure is proportionate to the objective pursued.
      
      65.  The dispute in the main proceedings concerns a question of European law raised before a national court. It is subject in principle
      to national rules of procedure, including rules of evidence. The case-law of the Court lays down a number of requirements
      in that regard. To wit, rules of evidence cannot render virtually impossible or excessively difficult the implementation of
      Community legislation.  
      
         			(13)
         		 Moreover, the rules of evidence laid down in the relevant national law cannot be less favourable than those governing similar
      domestic procedures.  
      
         			(14)
         		
      66.  It is settled case-law that a derogation from the principle of free movement of goods set out in Article 30 EC can be justified
      only where the national authorities demonstrate that that derogation is necessary to achieve one or several objectives which
      are set out therein and that the derogation is consistent with the principle of proportionality.  
      
         			(15)
         		 That also applies to preliminary ruling proceedings brought before the Court in the context of Article 28 EC in which a Member
      State relies on an imperative requirement to justify an obstacle to the free movement of goods. In such circumstances, the
      Court examines the ground relied on by the Member State and analyses whether there is any tangible evidence that it actually
      exists, is necessary and is proportionate. Where necessary, the Court advises the national court of all the factors it must
      take into consideration in its assessment. The rule that a national authority must demonstrate that the derogation in question
      is permitted under Community law cannot be different under national rules of procedure.
      
      67.  This means that the imperative requirements or overriding reasons must be defined so specifically as to make it possible to
      assess whether the measure taken by the Member State is justified as such. This degree of definition is also necessary because
      it would otherwise be impossible to assess whether the national rules at issue are effective and proportionate, that is to
      say whether or not they go beyond what is strictly necessary as regards the interest to be protected.
      
      68.  Such an assessment would have to take into account the fact that many characteristics of alarm systems and networks ─ and
      of their components ─ have already been harmonised by the three directives referred to above. In other words, the Belgian
      legislation and regulations now apply to only a few outstanding characteristics. None the less, application of the Belgian
      legislation and regulations means that the apparatus as a whole is subject to mandatory prior approval, which completely undermines
      the free movement of those goods achieved by the directives. National legislation which has such a consequence is readily
      classifiable as disproportionate since the protection of a limited public interest in a few outstanding non-harmonised characteristics
      makes the result sought through harmonisation of most of the other characteristics ─ freedom of movement ─ unachievable.
      
      69.  To prevent that consequence, which I consider to be unacceptable, it is the responsibility of the national legislature, when
      laying down the rules governing certain outstanding characteristics of systems and apparatus, to take into account all the
      existing harmonisation rules applicable to other characteristics of that apparatus. The principle of Community solidarity
      contained in Article 10 EC imposes an obligation on legislatures to draw up their national legislation by reference to the
      requirements and procedures to which Community law subjects those products ─ both components and apparatus. That means here
      that the national legislature should have confined itself either to recognising that apparatus lawfully marketed elsewhere
      in the Community conforms to standard or to setting up a system of subsequent checks as the relevant directives in this instance
      permit.
      
      
      
      
      
      C ─
      The third set of questions referred (Question 3) 
      70.  In the light of the answer to Question 1, it is not necessary to answer Question 3.
      
      
        V ─ Conclusion
      
      71.  On those grounds, I suggest that the Court answer the questions referred by the Belgian Conseil d'État as follows:
      
      72.  Question 1
      (a) Council Directive 73/23/EEC of 19 February 1973 on the harmonisation of the laws of Member States relating to electrical equipment
      designed for use within certain voltage limits, Council Directive 89/336/EEC of 3 May 1989 on the approximation of the laws
      of the Member States relating to electromagnetic compatibility and Directive 1999/5/EC of 9 March 1999 of the European Parliament
      and of the Council on radio equipment and telecommunications terminal equipment and the mutual recognition of their conformity
      must be interpreted as being applicable to alarm systems and networks, in particular to products of that type which use radio
      transmission, commonly known as wireless alarm systems. 
      
      (b) It follows from Directives 73/23/EEC, 89/336/EEC and 1999/5/EC that, in the fields covered by those directives, the Member
      States cannot make marketing of components and finished products subject to requirements other than those which are expressly
      provided for in those directives. It follows that provisions laid down by law or administrative action which have the purpose
      or effect of imposing such excessive requirements are incompatible with those directives. 
      
      
      
      73.  Question 2
      
      
      ─
         The harmonisation achieved by Directives 73/23/EEC, 89/336/EEC and 1999/5/EC entails a presumption of conformity to standard,
         which includes the procedures for assessment of conformity to standard, in relation to apparatus bearing the CE marking. Article
         3 of Directive 73/23/EEC, Article 5 of Directive 89/336/EEC and Article 6(1) and Article 8(1) of Directive 1999/5/EC therefore
         preclude national provisions such as Article 12 of the Law of 10 April 1990 and Article 9 of the Royal Decree of 23 April
         1999, which make the placing on the market in a Member State of all alarm systems and networks lawfully produced and/or marketed
         in another Member State subject to a prior approval procedure relating to components of those alarm systems and networks which
         satisfy the requirements of the directives referred to. 
      
      
      
      ─
         Articles 28 to 30 EC must be interpreted as meaning that, even in the absence of Community harmonisation rules, products lawfully
         produced and marketed in a Member State can in principle be sold in any other Member State without being subject to further
         checks. National rules making the placing on the market of alarm systems and networks subject, in respect of outstanding characteristics
         and functions not covered by harmonisation measures, to checks and tests concerning the prior approval or to the ability to
         produce certificates establishing that the apparatus in question satisfies the same requirements as are imposed by the national
         rules, therefore hinder the free movement of goods. Such rules must satisfy the conditions for derogation laid down in Article
         30 EC or another imperative requirement in the public interest established by Community law. They must be necessary to attain
         the objective pursued and must not go beyond what is strictly necessary for that purpose. 
      
      
      
      ─
         The adducing of evidence is governed by national rules of procedure. None the less, the national court must ensure the effective
         application of Community law. The effective application of Articles 28 and 30 EC therefore requires that, in the event of
         a restriction of a fundamental freedom, the national court must be able to ascertain whether the ground of justification relied
         on is compatible with Community law. This means that a national authority which relies on a ground justifying a restriction
         of the free movement of goods must provide tangible evidence that there is a public interest to be protected, that the measure
         is necessary and that it is proportionate to the objective to be attained. When assessing the proportionality of the national
         measure, the national court must also determine what impact it has on the effectiveness of the existing harmonisation measures
         and whether it is compatible with them.
