1 Introduction

For the purpose of this article, National Regulatory Authorities (NRAs) are defined as administrative authorities, established at Member State level, that are separate from the central state administration and that are entrusted with specific regulatory or supervisoryFootnote 1 missions that involve the implementation of EU legislation. NRAs operate in various regulatory domains, that range from media regulation to the safety of nuclear installations or the investigation of maritime accidents. Naturally, the respective missions and powers of all these bodies differ considerably.

NRAs are not necessarily IRAs, i.e. Independent Regulatory Authorities. What defines NRAs is their ‘separateness’. They are highly specialised bodies with a narrow mandate, who develop a specific expertise in a well-defined domain, allowing them to benefit from economies of scale, since they deal with high numbers of similar cases.Footnote 2 IRAs on the other hand are NRAs that enjoy a specific degree of independence, both from the regulated or supervised parties and from other public bodies, especially the political executive. In some areas, EU legislation explicitly requires independence. NRAs operating in the network industries are the best known examples of this trend and will be central to this article.Footnote 3 In the field of electronic communications, the CJEU has ruled on various occasions that, although Member States enjoy institutional autonomy as regards the organisation and the structuring of NRAs, that autonomy may be exercised only in full compliance with the objectives and obligations laid down in the directives.Footnote 4 Hence, the principle of institutional autonomy does not seem to have constitutional value: the EU legislature can limit Member States’ autonomy in this respect by laying down provisions of an institutional nature.

In the regulatory domains of energy (electricity and gas) and railway transport, the relevant EU legislationFootnote 5 currently contains the most straightforward obligations on the political independence of NRAs, which is the most controversial aspect of the twofold independence requirement.Footnote 6 In a more indirect way, such an obligation of political independence also follows from the (consolidated version of the) Framework Directive in the field of electronic communications.Footnote 7 For postal services, the legislative framework currently only anchors an obligation of independence vis-à-vis the regulated parties.Footnote 8 A European Commission proposal to amend the Audiovisual Media Services Directive contains provisions on the independence of media regulators.Footnote 9

EU law, however, is not only becoming more specific when it comes to the institutional design of NRAs. It also increasingly specifies the competences that NRAs should be invested with. Hence, EU law is a direct source of missions and powers for specific bodies within the domestic administrative apparatus. The following section briefly maps this influence. The article then turns to the more normative question of accountability.

2 The missions and powers of NRAs operating in the network industries: features

2.1 NRAs are typically single-purpose bodies

Even though NRAs are defined by the specificity of their mandate, EU legislation sometimes explicitly allows for the creation of multi-purpose bodies. An example is found in the latest directive on the liberalisation of the railway sector, which allows the competent regulatory authority to merge with the national competition authority, as long as the joint body fulfils the independence requirements laid down in the directive.Footnote 10 Recently, the ECJ has ruled that the Framework Directive (in the area of electronic communications) does not preclude national legislation which entails the merger of a national regulatory authority with other national regulatory authorities in order to create a multisectoral regulatory body. In performing its tasks, however, the body has to meet the requirements of competence, independence, impartiality and transparency laid down in the Framework Directive and an effective right of appeal to a body independent of the parties involved has to be available against its decisions.Footnote 11 In the Netherlands, for instance, a unified market supervisory authority was established in 2013.Footnote 12 In France, the regulatory body competent for the markets of electronic communications and postal services is the same,Footnote 13 as is the case in BelgiumFootnote 14.

2.2 Missions versus powers

There is great legislative variety in the way in which the missions and powers of NRAs are defined and delineated. What seems to be constant in the network industries, is that the provisions become more detailed or sophisticated with every new generation of directives.

The directives do not always make a clear distinction between the missions that NRAs should be made responsible for and the powers that Member States should invest them with. The concept of ‘missions’ refers to the substantive scope of NRAs’ competences, whereas ‘powers’ are the formal instruments of decision making and especially the coercive powers that they possess. In the field of railway transport, for instance, one article in the Directive is dedicated to the ‘functions’ of NRAs and covers both their missions and powers.Footnote 15 In the field of regulation of the energy markets, on the other hand, the directive more or less clearly upholds the distinction between objectives, ‘duties’ (i.e. missions) and powers of the NRA.Footnote 16

2.3 Broad discretionary powers

It has been argued that independent agencies ‘are an independent locus of policy ‘creation’ not ‘administration.”Footnote 17 NRAs indeed exercise their powers with considerable discretion. There is a direct and linear relationship between the degree of (political) independence that these authorities enjoy and the nature and impact of the powers that they are invested with. Others have noted that the CJEUFootnote 18 tends to interpret NRAs’ competences or missions in the network industries in a broad, rather than a narrow sense.Footnote 19 Regularly, however, there is a discrepancy between the intention of the EU legislature regarding the powers that NRAs should have and the actual implementation at the national level. National legislatures are not always keen to invest separate, let alone independent, authorities with broad decision-making powers. In Belgium, for instance, the federal energy regulatory authority turned to the Constitutional Court in 2013 because it believed that the legislature had not correctly transposed the third energy liberalisation package into national law. It more precisely claimed that the statute did not fully guarantee that it could exercise all the powers that EU law reserved for the regulatory body with full independence. The Constitutional Court indeed annulled some of the statutory provisions that were challenged.Footnote 20 In another judgment, pronounced in 2016, the Court annulled a provision of a Walloon decree that limited the discretionary power of the competent regulatory authority (the Walloon regulatory authority for energy) to decide on a tariff methodology. Again, it was the affected regulatory body itself that initiated the proceedings before the Court.Footnote 21 There are many other domestic examples of what other authors have labelled the ‘fragile position’ of NRAs in domestic law,Footnote 22 i.e. attempts by national legislatures or governments to curtail the powers of NRAs in the network industries or to limit their independence. These conservative reflexes at the domestic level do not come as a surprise. Typically, the combination of broad discretionary powers with a lack of political oversight is hard to reconcile with national constitutional principles governing administrative organisation.Footnote 23

2.4 A combination of advisory powers, coercive powers and investigatory powers

Most NRAs possess three types of powers. Firstly, they give advice to central state institutions; legislatures and governments. Secondly, they possess coercive powers: i.e. binding unilateral decision-making powers that create rights for individuals or impose obligations or burdens on them. Thirdly, they have a number of supportive powers, i.e. powers that are accessory to their coercive decision-making powers. Examples of the latter are powers to require information, powers of investigation and auditing powers. In the area of railway transport, for instance, the regulatory body has to be invested with the power to request relevant information from the infrastructure manager, applicants and any third party involved within the Member State concerned. The NRA should be able to enforce such requests with appropriate penalties, including fines.Footnote 24 In the area of regulation of the electricity markets, the NRA should enjoy the power to carry out inspections, including unannounced ones, on the premises of the vertically integrated undertaking and the transmission system operator.Footnote 25

2.5 A combination of normative, adjudicatory and enforcement powers

Many NRAs combine aspects of the three traditional functions of the state. Firstly, they have normative powers, meaning that they can issue rules that are applicable to all or to a predefined group of (regulated) parties. Examples are found, for instance, in the area of the regulation of postal services, where the NRA can to some extent derogate from or give a different content to the scope of the universal service obligation (e.g. increase the weight limit to any weight not exceeding 20 kilograms or lay down specific arrangements for the door-to-door delivery).Footnote 26 NRAs in charge of the regulation of the energy markets should have the power to fix or approve, in accordance with transparent criteria, transmission or distribution tariffs or their methodologies.Footnote 27 They also set or approve standards and requirements for quality of service and supply or contribute thereto with other competent authorities.Footnote 28

Secondly, NRAs have powers to take decisions with an individual scope. An example, again in the field of energy regulation, is the power to approve commercial and financial agreements between vertically integrated undertakings and transmission system operators.Footnote 29

Finally, NRAs have powers of enforcement, i.e. quasi-judicial powers. Some NRAs are invested with powers to issue binding decisions in order to resolve disputes. Examples are found in the areas of electronic communications,Footnote 30 energyFootnote 31 and railway transport.Footnote 32 NRAs may also have powers to impose penalties after complaints or even ex officio. In the area of railway transport, the directive requires the competent regulatory body to be able to enforce its decisions with the appropriate penalties, including finesFootnote 33. Electricity regulators should be invested with the power to impose effective, proportionate and dissuasive penalties on electricity undertakings not complying with their obligations. However, in this case, the directive provides an alternative: the national legislature can also decide to give the NRA the mere possibility of proposing to impose such penalties to a competent court.Footnote 34 An interpretative note issued by the European Commission clarifies that the latter possibility was included in the directives because the constitutional system of some Member States does not permit that independent bodies would be invested with sanctioning powers.Footnote 35

The combination of such a variety of powers in the hands of a single administrative body as such may also not be obvious in light of national constitutional approaches to the separation of powers doctrine.Footnote 36 However, nothing in the directives seems to prevent Member States from creating subsections within regulatory bodies in order to ensure that different individuals are in charge of these different functions. In France, for instance, the Conseil Constitutionnel verifies whether the institutional design of regulatory bodies with sanctioning powers guarantees a functional separation between the stages of prosecution and adjudication.Footnote 37

2.6 Powers of NRAs versus powers of NCAs

Economic regulation in EU law consists of two components: general competition law (enforced, at the national level, by the NCAs or National Competition Authorities) on the one hand and sector-specific regulation (enforced by NRAs) on the other hand.Footnote 38 According to most literature, there is a preference for sector-specific regulation if and as long as specific ex-ante obligations of a preventive nature are necessary to reduce the risk of market failures: ‘[i]n later stages and as competition intensifies, sector-specific rules are gradually replaced by general competition rules.’Footnote 39 Roughly, regulatory authorities are responsible for ex ante regulation in recently liberalised markets with a history of monopolies and high risks for the public interest(s) at stake. General competition authorities, on the other hand, act ex post facto and the scope of their supervision extends to all markets that are subject to competition.Footnote 40 The powers that are typically granted to each type of authority correspond to these different roles: whereas regulators mainly operate through powers of rule making and adjudication (e.g. licensing), general competition authorities’ remit tends to focus more on dispute resolution and sanctioning, implying that their decisions are often quasi-judicial in nature. The picture, however, is not black and white. As we have seen, NRAs increasingly possess such quasi-judicial powers as well. Competition authorities, on the other hand, also have ex ante powers (notably with respect to merger control).

We have seen that EU legislation itself determines which missions and powers NRAs in the network industries have to be invested with (as a minimumFootnote 41). The situation for NCAs is by no means comparable: there is a great variety among Member States when it comes to the powers that they invest their NCAs with. For that reason, the European Commission recently launched a proposal for a directive that aims to reinforce the position of NCAs. The proposal amongst other things anchors the principle of independence for NCAs (in much the same way as the liberalisation directives do for NRAs) and specifies the power that these bodies should possess.Footnote 42

3 Questions of accountability

Due to their independence, IRAs lack the democratic legitimacy that other administrative authorities derive from their connection to the political executive. They are not subject to traditional forms of political oversight.Footnote 43 Other accountability mechanisms apply to them, however.Footnote 44 As the provisions in EU legislation on the precise missions and powers that NRAs should possess become ever more detailed, so does the attention for their accountability. This is mainly true for two types of accountability: accountability through procedural guarantees and legal accountability.Footnote 45 We also briefly address two accountability mechanisms that are located at the supranational level: network accountability and accountability to the European Commission.

3.1 Procedural accountability

Procedural accountability takes place via mechanisms that make regulators answer to regulated parties and stakeholders during the administrative process. Ideally, these mechanisms can even lead to a dialogue. Participatory mechanisms are central to this type of accountability. EU legislation now often enshrines requirements or duties for NRAs to consult stakeholders in general or specific regulated parties for particular decisions.Footnote 46 For these mechanisms to be effective in practice, it is key that NRAs offer sufficient levels of transparency. Therefore, EU legislation often explicitly requires NRAs to publish their decisions (with respect for the confidentiality of commercially sensitive information).Footnote 47 Participation can only lead to accountability, however, if the NRA also explains how it has used the input that it received, to what extent it has implemented suggestions etc. Many NRAs have strongly invested in the design of their consultation procedures and experiment with different types of participation. The Dutch unified market supervisory authority ACM, for instance, organises consultations regarding the policy rules that it issues. Sometimes, stakeholders are invited to submit comments on the regulator’s website. In other cases, however, the ACM has been known to organise roundtables that allow for a genuine debate.Footnote 48

NRAs are furthermore subject to the general principles of good administration, such as the right to be heard or to have a case handled within a reasonable time. Article 41 of the Charter of Fundamental Rights of the European Union has given good administration the status of a fundamental right. Contrary to the other fundamental rights in the Charter,Footnote 49 the right to good administration only applies to the institutions and bodies of the Union, but not to the Member States when they implement or act within the scope of EU law.Footnote 50 NRAs may be ‘agents of EU law”; from an institutional viewpoint, they are embedded in the Member States’ administrative systems. The principles of good administration, however, have been developed by the CJEU as part of the EU’s unwritten law. These principles remain relevant for the Member States and their administrative bodies, even if the scope of the codified right to good administration does not include them.Footnote 51 The body of principles of good administration recognised by the CJEU (or in the European Code of Good Administrative Behaviour) is, moreover, more extensive than the list that figures in Article 41 of the Charter, which, amongst others, does not mention the proportionality principle, the principle of legal certainty or the principle of due care.

Because NRAs fall under the scope of both national and EU principles of good administration, meaning that the highest level of protection for individuals will prevail, their decision-making process often reaches higher degrees of procedural fairness than that of central administrations. An illustration is found in the case law of the Brussels Court of Appeal in a case against the Belgian federal energy regulatory authority. The case concerned another important guarantee of procedural accountability: the duty to give reasons. The NRA argued that its tariff decision did not have to contain reasons, since the Belgian statute anchoring the duty to give reasons for administrative acts only applies to decisions with an individual scope, not to normative acts.Footnote 52 The Court, however, referred to Article 37(16) of Directive 2009/72, providing that decisions taken by regulatory authorities shall be fully reasoned and justified to allow for judicial review.Footnote 53 This article does not limit the duty to give reasons to acts with an individual scope (the same is true for the duty to give reasons as a general principle of good administration in EU lawFootnote 54). Hence, the NRA has to give reasons for its normative acts as well, whereas most other Belgian administrative authorities are not obliged to do so.

3.2 Legal accountability

Another important form of accountability takes place in the courts. There is a remarkable variety in the way that the EU legislative frameworks on network regulation phrase the guarantees that Member States have to offer in this regard. In the field of railway transport,Footnote 55 for instance, the legislation uses the term ‘judicial review’, whereas the legislation in the fields of energy,Footnote 56 electronic communicationsFootnote 57 and postal servicesFootnote 58 speak of an appeal to a ‘body which is independent of the parties involved’. In the field of energy, the directives clarify that this body also has to be independent of any government. The Framework Directive for electronic communication clarifies that the appeal body ‘may be a court’; if it is not judicial in nature, the directive submits it to a duty to give reasons and orders that it shall be subject to review by a court or a tribunal. It is unclear how these differences in formulation should be interpreted. Does the EU legislature indeed impose different standards for different NRAs and—if so—what is the justification for this?

The directives offer little further guidance on the design of the judicial review process, especially in terms of the intensity of the review and of the remedies that the judge should be able to offer.Footnote 59 The CJEU, however, has pronounced a few interesting judgments in this respect.

The Court has endorsed the legal accountability of NRAs in T-Mobile Austria,Footnote 60 which was a case about locus standi. Article 4(1) of the Framework Directive provides that the appeal mechanism against NRA decisions at the national level must be open to any user or undertaking providing electronic communications networks and/or services who is affected by the decision that is being challenged. The referring court wanted to know whether this also included an undertaking holding rights to use radio frequencies and competing with the parties to a procedure for the authorisation of a transfer of rights to use radio frequencies. Referring to the interpretation that it gave to Article 4(1) of the Framework Directive in its Tele2 judgment,Footnote 61 the CJEU ruled that ‘a strict interpretation of Article 4(1) of the Framework Directive to the effect that that provision confers a right of appeal only on persons to whom the decisions of the NRAs are addressed would be difficult to reconcile with the general objectives and regulatory principles resulting, for the NRAs, from Article 8 of that directive, and, in particular, with the objective of promoting competition’.Footnote 62 Potential competitors of the addressee of a decision should consequently also have access to the court, in so far as the NRA’s decision is adopted in the context of a procedure intended to safeguard competition and is likely to have an impact on their position on the market.Footnote 63 The Court decided that these conditions were met in the case pending before the national judge.

In a recent judgment, the CJEU ruled that a national court hearing an appeal against a decision of an NRA competent in the field of electronic communications must be able to annul that decision with retroactive effect, if it finds that to be necessary in order to provide effective protection for the rights of the undertaking who has brought the appeal.Footnote 64 The Court referred specifically to Article 4(1) of the Framework Directive, anchoring the right of appeal against NRA decisions, but indicated that this article is an expression of the principle of effective judicial protection safeguarded by Article 47 of the Charter of Fundamental Rights of the European Union, pursuant to which it is for the courts of the Member States to ensure judicial protection of an individual’s rights under EU law.Footnote 65

Hence, the CJEU gives a broad interpretation to the right to effective judicial protection vis-à-vis decisions made by NRAs, both on the level of who has access to the courts and on the level of the remedy that the courts should be able to offer.

Another recent judgment of the CJEU, Koninklijke KPN NV et al., sheds light on the intensity of the judicial scrutiny of NRAs’ decisions and more precisely on the proportionality test. At the basis of the case was a decision of the Dutch ACM setting price caps for fixed and mobile call termination services. The referring court amongst other things wanted to know whether it was allowed to assess the proportionality of the obligations laid down in this decision in the light of the objectives set out in Article 8 of the Framework Directive and Article 13 of the Access Directive.Footnote 66 The CJEU ruled that the national judge may check whether the applicants have adduced sufficient evidence to show that the application of this model is not proportionate to the objectives set out in Article 8 of the Framework Directive and in Article 13 of Access Directive, in view, as appropriate, of the specific characteristics of the relevant market. The NRA’s tariff obligations must be directed at achieving these objectives. The national court is not entitled, however, when carrying out a judicial review of a decision of the national regulatory authority, to require that authority to demonstrate that the obligation actually attains the objectives set out in Article 8 of the Framework Directive, as amended by Directive 2009/140.Footnote 67 According to the Court, the adoption of regulatory obligations is based on a prospective analysis of market developments. Therefore, the proof that such measures attain the objectives set out in the Directive is ‘impossible or excessively difficult to adduce’.Footnote 68

It has been argued that the CJEU devises the proportionality test differently depending on the authority under review: it tends to be stricter when a national authority is involved than when an EU institution is under scrutiny. The reason is that the Court wants to foster European integration.Footnote 69 Decisions made by national authorities are often challenged precisely because they limit the rights and freedoms conferred on individuals by EU law with the aim of reinforcing the internal market. NRAs, however, as the title of this article suggests, are ‘agents of EU law’. Because of their independence from the national political arena, NRAs in the network industries specifically are considered as loyal partners of the EU institutions. They are less suspected than central national administrations of pursuing national interests rather than European ones. This, along with other factors, may explain why the CJEU prevents the proportionality test from being overburdening in this case.

The degree of scrutiny that the courts apply when they review NRAs’ decisions nevertheless has important consequences for the effectiveness of judicial review. These decisions are technical in nature and are preceded by thorough (economic) research in order to obtain evidence for the policies pursued. Even though courts are becoming increasingly well-equipped to review regulatory processes in terms of expertise or knowledge,Footnote 70 time constraints or a lack of resources sometimes hamper the courts’ ability to assess the substantive quality of regulatory decisions. As Ottow points out, the burden of proof that the courts place on the shoulders of market authorities may therefore be high: courts demand actual proof from NRAs that justifies their intervention.Footnote 71 In its Koninklijke KPN judgment, however, the CJEU mitigates the burden of proof that can be imposed on NRAs. In this case the question revolved around more than tasking the NRA to prove that the facts underlying its decision had been properly established and backed up by economic evidence. The national court went one step further still and asked the NRA to prove that its policy would be effective, i.e. would lead to a certain outcome.

The dilemma that courts face with regard to the standard of review of NRAs’ decisions is often presented as being twofold: either they defer to regulators’ decisions and expertise or they ‘engage in fresh examinations of the merits of decisions’.Footnote 72 In reality, of course, there are various ‘in-betweens’: some courts have, for instance, adopted a procedural approach to the proportionality review. This may also imply that the regulatory body is asked to provide evidence, but this then mostly relates to the design and execution of the decision-making process.Footnote 73 The preliminary question formulated by the Dutch court in Koninklijke KPN, however, suggests that NRAs could also be asked to provide evidence for the substantive rationality of their decisions. In this way, they actively contribute to the proportionality test by substantiating the suitability of their policies. In its judgment, the CJEU confirms that the national courts can assess whether the NRA’s decisions are proportionate in the light of the objectives of EU legislation, but cannot ask the NRA to demonstrate that the obligation actually attains the objectives. This judgment should most likely be interpreted in such a way that courts cannot expect NRAs to provide conclusive evidence that their decisions will fulfil these objectives. However, it should be possible for courts to ask regulators to actively demonstrate the probability of their policies effectively contributing to the objectives that they are legally bound to pursue.

This point deserves to be pressed precisely because the broad discretionary powers that NRAs in the network industries enjoy seem to have only one substantive limit: they are justified by and can therefore only be used to achieve the goals that the EU legislature has defined in the relevant legislative framework. If the national courts cannot assess whether the NRA’s decisions indeed contribute to those goals, the prohibition of arbitrary rulemaking is hollowed. It seems reasonable and fair, considering the duty to give reasons that rests on NRAs as part of their procedural accountability, to impose a duty of cooperation on them with the aim of assisting the court in carrying out the proportionality test.Footnote 74 In its Arcor judgment (2008), the CJEU ruled that, considering the lack of any rules laid down in EU law, it is up to the Member States to establish, in accordance with their rules of procedure, the rules of evidence applicable, including the allocation of the burden of proof between the NRA that made a decision and the party challenging that decision. This competence, of course, has to be exercised in accordance with the Community principles of effectiveness and equivalence of judicial protection.Footnote 75

3.3 Network accountability and the supervisory powers of the European Commission

The various directives contain provisions that oblige NRAs in different Member States to cooperate with each other in various ways.Footnote 76 The so called ‘network agencies’ at the EU level, such as ACER (Agency for the Cooperation of Energy Regulators) and BEREC (Body of European Regulators for Electronic Communications) play an important role in this regard. At present, the tasks of these agencies are mostly about coordinating, monitoring and advising on the work of NRAs. It has moreover been argued that these networks function as fora for accountability, since peers in networks watch each other and raise the need for self-justification in the light of self-preservation.Footnote 77 In the future, though, they may be moving beyond that role. The European Commission has plans, for instance, to give ACER decision-making powers for cross-border issues that require a coordinated regional decision.Footnote 78

In some cases, the European Commission itself possesses powers of oversight vis-à-vis NRA decisions in the form of binding vetoes against NRA drafts. These powers are rare,Footnote 79 but remarkable from a constitutional viewpoint. They give the central European executive a power to directly intervene in a decision issued by a national administrative authority.

4 Conclusion: NRAs in ‘no man’s land’?

The Oxford English dictionary gives several definitions for the word ‘agent’. At least two of these seem applicable to NRAs. The first is: ‘one who exerts power’. This article demonstrated that NRAs hold several powers of various natures. In the network industries especially, NRAs’ functional independence implies that they (should) exercise these powers autonomously, without any direct possibilities of oversight by national political principals. The second definition is: ‘a person acting on behalf of another’. NRAs in the network industries are often seen as special kinds of independent ‘agencies’. But if they are ‘agents’ or ‘agencies’, who is their ‘principal’? On whose ‘behalf’ do they act? This is a complex question without a simple answer. NRAs lack a single principal to whom they answer or who possesses certain powers of intervention vis-à-vis their actions. They are, as this title suggests, agents of EU law, which they are supposed to implement and enforce faithfully. They answer to several fora of accountability (the European Commission, national parliaments, stakeholders, the courts, other NRAs with whom they form networks etc.), with none of these exercising complete control over their actions.

This contribution paid special attention to the judicial review of NRAs’ decisions. Even though accountability to the courts cannot fill the political legitimacy gap that these bodies suffer from,Footnote 80 it is important that judicial review of NRAs’ decisions is effective. This article discussed some interesting case law of the CJEU in this respect. NRAs may find themselves in no man’s land on the politico-institutional map; they are on the national courts’ radar. These national courts increasingly turn to the CJEU to explore the conditions and the boundaries of the scrutiny that they can exercise and the remedies that they can offer.
