B. The Scope and the Functioning of EU Inspection Powers

Over the last fifteen years, several European administrations have been given powers of inspection. The analysis will divide the inspection powers of EU authorities into two groups.

In the first group of sectors—competition, financial, and aviation—not only are inspection powers given to EU authorities, but also the sanctioning powers that can be activated based on the results of such inspections.Footnote ¹² In the second group of cases, though, the inspecting authorities are not competent for adopting the final sanction, so that a mixed, top-down procedure takes place.Footnote ¹³ This is the case of the European Anti-Fraud Office (OLAF), the European Fisheries Control Agency (EFCA), and the Commission in the area of Food Safety. In the banking sector, both scenarios can emerge, as the European Central Bank (ECB), which conducts inspections on significant credit institutions through mixed teams, can decide on sanctions or can ask national authorities to start a sanctioning proceeding according to a complex system of division of competences.Footnote ¹⁴ In the second group of cases, as well as when ECB inspections result in sanctions from National Competent Authorities (NCAs), the establishment of a system of effective judicial protection for the inspected parties is particularly challenging as inspection reports—which serve as preparatory acts in the decision-making process and lack any binding legal effect—are generally considered non-reviewable in annulment actions under Article 263 TFEU.Footnote ¹⁵

As mentioned above, the first group includes the competition, banking, financial, and aviation sectors. It is widely known that competition is the area where inspection powers have long been established: The powers of inspection of the Commission were provided for by Regulation No. 17/62 and broadened in Regulation No. 1/2003.^{Footnote 16} Within the latter, the division of labor between the Commission and the NCAs, which are part of the European Competition Network (ECN), follow the criteria of parallel competences.Footnote ¹⁷ The scope and functioning of inspection powers in the competition field have clearly been used as a template for the inspection powers assigned to the ECB and the European Securities and Markets Authority (ESMA) following the global financial crisis of 2008. Within the Single Supervisory Mechanism (SSM), the first of the pillars of the European Banking Union (EBU), the Supervisory Committee of the ECB is responsible for overseeing credit institutions in eurozone Member States whose importance is “significant,” according to parameters concerning the size and propensity of risk of the operators. Below this threshold, competence lies with the national authorities.^{Footnote 18} ESMA, an EU agency, over time has been assigned direct supervisory and control powers, including powers of inspection,Footnote ¹⁹ with respect to only some specific operators, such as credit rating agencies (CRAs), ^{Footnote 20} trade repositories (TRs), central clearing counterparts of third countries (CCP), ^{Footnote 21} and other providers of financial information.Footnote ²² Within this first group, the European Aviation Safety Agency (EASA) Footnote ²³ can also be considered, even though there are some differences.Footnote ²⁴ For example, this agency can carry out inspections on both undertakings and “monitoring” of Member States competent authorities.Footnote ²⁵ EASA can act as an “inspector of inspectors.”Footnote ²⁶

The inspecting powers of the Commission, of the ECB, the ESMA, and the EASA include: a) access to the premises of the companies, banks, financial operators, and lands or means of transport, respectively; b) checking the documents and any other relevant material; c) making copies of such documents and materials; and d) asking for written and oral explanations.^{Footnote 27} However, while in the banking, financial, and aviation areas access is restricted to the professional premises, in the competition area, the inspectors can also access the residence of the managers, directors, or other members of the company staff—a novelty introduced in 2003. Moreover, in the competition and the financial areas, the inspectors can seal the premises and company documents for the duration of the investigations to the extent necessary for their completion.^{Footnote 28} Comparatively, in the case of bank inspections, this power stays in the domain of the national competent authority, and in the case of aviation, this power is not mentioned.^{Footnote 29} Further, the ESMA alone can request documentation also relating to telephone and data traffic.^{Footnote 30}

Regarding the substantial conditions for the activation of powers of inspection, all the regulations require that this has to be “necessary” for the functions attributed to EU authorities. In the case of competition home inspections, there must also be a reasonable suspicion that company records are kept on these premises and that these documents are relevant in proving a “serious” infringement of European competition law.^{Footnote 31} In regard to the procedural conditions, in the competition and the financial sectors, inspections can be carried out either upon simple authorization or on the basis of a decision of the Commission or the ESMA, respectively; a decision of the ECB or the EASA is always necessary in the banking and aviation areas, and for domiciliary inspections in the competition area. ^{Footnote 32} The effects are different: Only when the inspection is decided with a decision, the recipients of the inspections are obliged to undergo inspection. If they refuse, they are subject to pecuniary penalties.^{Footnote 33} Moreover, in case of opposition to an inspection ordered on the basis of a decision, the inspected entities can be obliged with the use of force. However, European officials do not have such power. In this event, the Member State has to provide the necessary assistance, employing the police or an equivalent authority.^{Footnote 34}

In the competition, banking, and financial sectors, the same EU authority has the power to inspect and, later on, to use the results gathered during the investigation to impose sanctions. However, as already mentioned,Footnote ³⁵ this is not always the case in the banking sector, as a complex division of sanctioning competences is established between the ECB and NCAs.Footnote ³⁶ In the area of aviation safety, the inspecting authority is not also the one competent for sanctions, as EASA does not itself decide on sanctions: It shall propose them to the Commission, that retains such competence.Footnote ³⁷ However, because the sanctioning authority is the Commission, the administrative procedure takes place entirely at the EU level.

In the four sectors examined so far, the decision to inspect is taken by an EU authority, which also performs the inspection activities. Moreover, an EU authority can also adopt sanctions on the basis of the results of the inspection. However, there are many instruments of collaboration between the EU inspecting authority and the authorities of the Member State in which the inspection is carried out. On the one hand, before the inspection, the EU authority has to notify or consult the national one in good time.^{Footnote 38} On the other hand, in the investigation phase, the national authority is obliged to assist the EU. Such cooperation, as mentioned above, is crucial in case of opposition from the inspected entity. ^{Footnote 39} In these cases, national authorities play a supporting role within an administrative procedure that is started and closed at the EU level. However, in the banking and the aviation sectors, a closer mechanism of integration takes place, as the inspection groups have a mixed composition, in which both EU officers and national ones take part.Footnote ⁴⁰

A more complex allocation of competences at the EU and national level takes place in the second group of cases, for example, the case of inspections of the European Anti-Fraud Office (OLAF), the European Fisheries Control Agency (EFCA), and the Directorate on Health and Food Audits and Analysis within the DG Health and Food Safety (Directorate-F).

OLAF—an internal office of the Commission, albeit enjoying autonomy and operational independence—was established in 1999, following the scandal that led to the resignation of the Santer Commission.^{Footnote 41} OLAF’s functions were originally governed by Regulation No. 1073/1999, later replaced by Regulation No. 883/2013,^{Footnote 42} following numerous criticisms regarding the insufficiency of guarantees provided by OLAF for individuals.^{Footnote 43} The subject of the administrative investigations of OLAF is confined to fraud and administrative irregularities which damage the financial interests of the EU. The newly established European Public Prosecutor Office (EPPO) has not absorbed OLAF’s competences, as the first one is exclusively competent for criminal offenses and not administrative irregularities;Footnote ⁴⁴ yet, the need for coordination, according to the principles of cooperation and non-duplication of the investigation established in EPPO regulation is strong. Together with the aim of enhancing the effectiveness of OLAF’s investigations, the purpose of facilitating coordination with EPPO is the primary reason for which Regulation No. 883/2013 has been recently reformed.Footnote ⁴⁵ OLAF inspections are divided into two types: Internal, in cases in which the activities under investigation are carried out by employees of European institutions, and external, where they are related to the conduct of economic operators in the territory of Member States.^{Footnote 46}

While OLAF can investigate any case harming the financial interests of the EU, in the other two sectors, the inspecting powers given at the EU level are carefully circumscribed. In fisheries, there is a broad responsibility of national authorities to control and inspect fishing activity. Inspection powers of EFCA,Footnote ⁴⁷ the EU agency responsible for fisheries, can be activated only upon very specific circumstances when EU vessels in international waters are concerned.Footnote ⁴⁸ Also, in the area of food safety, the primary responsibility to control is on national authorities. The Commission’s controls, performed by Directorate F, are aimed at controlling how the Member States perform such control.Footnote ⁴⁹ However, the Commission’s food safety on the spot verifications can also include access on business premisesFootnote ⁵⁰ so that such control, even though being indirect, can have in practice a direct effect on individuals, as the Bowland case shows.Footnote ⁵¹

The type of powers that can be used by these EU inspectors are similar to those examined for the competition, banking, financial, and aviation areas. They include controls and spot checks, access to information and documentation, extracting copies of documents, and requesting oral explanations.^{Footnote 52} The most intrusive powers given in the sectors examined above—to seal premises or gather telephone and data traffic—are not mentioned. However, OLAF is entrusted with two particularly intrusive powers. First, in addition to extracting copies of documents, the appointed officials may also, “if necessary,” take possession of them “to avoid any risk of subtraction.”^{Footnote 53} Second, according to the recently reformed OLAF Regulation, the Office shall have access to information also stored in privately owned devices, when used for work purposes, and to bank account information.^{Footnote 54}

The substantial and procedural conditions to activate the inspecting powers of EFCA and Directorate F are less specific than those that have been examined for the competition, banking, and financial areas. OLAF is an exception. A substantial condition for the initiation of an investigation is that there is sufficient suspicion to lead to the supposition of the existence of fraud, corruption, or other activity detrimental to the financial interests of the EU. From a procedural point of view, a decision of the Director-General is necessary in order to open an investigation.^{Footnote 55} The powers to be used during the inspections, however, are specified in a written authorization of the Director-General, not in a decision.^{Footnote 56} The economic operator has a duty to cooperate; however, if the economic operator resists the inspection, law enforcement authorities of the Member States shall provide assistance through the use of force.^{Footnote 57} Contrary to the competition, banking, and financial sectors, no pecuniary sanctions are specified in case of opposition.

As opposed to the first group of cases, in the area of the protection of financial interests, fisheries, and food safety, the competence for inspecting is separated from the one for sanctioning. At the end of the investigation, OLAF prepares a report describing the preliminary findings and recommendations. Those recommendations shall indicate disciplinary, administrative, financial, or judicial action to be taken by the institutions, bodies, offices, and agencies of the EU and by the competent authorities of the Member States concerned. Such recommendations have no binding legal effect on the EU or Member States authorities.Footnote ⁵⁸ It is up to the EU institution or national authorities to decide whether to proceed in taking administrative or judicial action. In the area of fisheries, EFCA does not sanction violations: It is in the competence of Member States to undertake all appropriate measures in respect of any infringement that a Community inspector has discovered.Footnote ⁵⁹ Similarly, in the area of food safety, at the end of its inspections, Directorate F produces reports that can be followed by actions by Member States.Footnote ⁶⁰

After examining the increasing phenomenon of EU authorities’ inspection powers, this Article will now examine the conditions under which these powers are lawful, according to the common principles stemming from the national constitutions of the Member States, the EUCFR, and the ECHR.

C. Inspection Powers, Fundamental Rights, and Judicial Review

As inspections are visits and checks conducted on business premises and documents, they always have an impact on the inviolability of the home. As documents are increasingly dematerialized and can be found in hard disks, emails, and the like, checks during inspections can have a bearing on the right to the inviolability of communications. One specific power examined above, ESMA’s power to gather telephone and data traffic, always affects the right to the inviolability of communications. What are the conditions for the public intervention intrusion on fundamental rights to be lawful?

The fundamental right to the inviolability of the home and communications is protected by the national constitutions of the Member States, the EUCFR, and the ECHR. A discussion of the evolution of the protection of fundamental rights in the EU, well known and extensively debated in the academic legal literature,Footnote ⁶¹ falls beyond the scope of this Article. However, in order to set forth the basis for assessing to which extent the different sources of protection of fundamental rights can limit the inspection powers of EU authorities, some rudimentary clarifications are needed.

Since the 70s, the Court of Justice started building an unwritten bill of rights, distilling general principles of law emerging from the common constitutional traditions of the Member States.Footnote ⁶² Along with national traditions, in the construction of this unwritten bill of rights, the ECHR has also played a key role as a source of inspiration.Footnote ⁶³ A written bill of rights for the EU, the EU Charter of fundamental rights, was then drafted in 2000. When approved, however, it lacked binding legal force. Since the Treaty of Lisbon, the three possible sources of protection of fundamental rights under EU law have been codified under Article 6 TEU: The EUCFR, according to Article 6(1), has the same legal value as the Treaties; the ECHR, to which Article 6(2) provides a basis for accession and Article 6(3) recognizes a source of general principles of EU law; and national constitutional traditions of the Member States, which are also a source of general principles of EU law under Article 6(3).

Because the EU Charter was made formally binding, the CJEU tends to rely on the provisions of this source in the majority of the cases. In contrast, the frequency of citations of the ECHR and the reference to national constitutional traditions as a source of the common principles of EU law have declined.Footnote ⁶⁴ However, the TEU does not establish a hierarchy among the three sources of protection of fundamental rights. A pluralistic understanding of the relation between these sources appears preferable, as a comparative approach can help identify gaps in the protection offered by the EU Charter.Footnote ⁶⁵

Further clarification is needed, as far as the ECHR is concerned. On the one hand, it is well known that the Court of Justice, with its opinion 2/13, blocked the process of accession in the short term.Footnote ⁶⁶ On the other hand, however, it must be born in mind that, even though the Treaties do not clarify the relation between the EUCFR and the ECHR, Article 52, paragraph 3, of the EU Charter itself specifies that “Insofar as this Charter contains rights which correspond to rights guaranteed by the Convention for the Protection of Human Rights and Fundamental Freedoms, the meaning and scope of those rights shall be the same as those laid down by the said Convention.” According to the Explanations to the Charter, the reference to the ECHR under Article 52, paragraph 3, covers not only the text of the Convention and the Protocols to it but also the meaning and the scope of the guaranteed rights as determined by the case law of the Strasbourg Court.Footnote ⁶⁷ Even if the legal value of these explanations is uncertain,Footnote ⁶⁸ in several cases, the CJEU has recognized that, when the provisions of the EU Charter correspond to those covered by the Convention, they shall have the same meaning and scope as interpreted by the Strasbourg Court.Footnote ⁶⁹ The approach of the Luxembourg Court, however, is far from settled, as in other cases the expression used is more generic, arguing that the ECHR case law needs “to be taken into consideration” in determining such meaning.Footnote ⁷⁰

In the following paragraphs, the different models of protection of the fundamental rights of the inviolability of the home and the secrecy of communications under national Constitutions, under the ECHR, and under the ECFR, will be examined, as they can constitute limits to the exercise of inspection powers of EU authorities. Only the use of a comparative methodology can help to understand the reasons behind different models of protection of fundamental rights and whether different models are equally effective in protecting such rights. Moreover, as will be seen, both the Court of Strasbourg and the Court of Luxembourg, albeit using different techniques of protection of fundamental rights, take into account conditions that are traditionally considered relevant under national constitutional traditions, notably through the proportionality test.

Under national constitutional law, the system of protection for the inviolability of the home and communications is generally based on two guarantees: First, that such power must be specified in a legislative act, and second, in some Member States, ex ante judicial authorization.Footnote ⁷¹ However, while all EU Member States’ national Constitutions require that any limitations shall have a legal basis, only some of them set forth that such limitation shall be authorized by a judge: For example, this is the case under French law, while the German and Italian Constitutions, albeit considering the principle, draw a distinction concerning the cases when such preventive judicial authorization is required.

Under French law, the Conseil Constitutionnel clearly stated that ex ante judicial authorization is necessary for public officials to enter private premises within administrative inspections.Footnote ⁷² In Germany, there is a distinction between Durchsuchungrecht, in which the use of force requires a prior warrant, and Einsichts und Prüfungsrecht, in which the searches are conducted with the consent of the inspected and hence, prior authorization is not needed.Footnote ⁷³ Article 14 of the Italian Constitution exempts administrative inspections from judicial authorization when this is needed for the purpose of objectives of public interest, and the Constitutional Court interpreted such distinction in a similar way to the German tradition, distinguishing between perquisizioni (use of force and hence the necessity of preventive authorization) and ispezioni (consent and no preventive authorization).Footnote ⁷⁴

The differences across national Constitutional traditions of the Member States on the requirement of ex ante judicial authorization for the inviolability of the home led the Court of Justice to find that such a requirement cannot be considered a general principle of EU law, as will be discussed in the following section.

After pointing out the differences existing within some national constitutions of the Member States, the analysis now turns to the ECHR and the EUCFR.

The inviolability of the home and the secrecy of communication are protected under Article 8 ECHR. In recognizing that “[e]veryone has the right to respect for his private and family life, his home and his correspondence,” Article 8 ECHR embraces four different interests: Private life, family life, home, and correspondence. Article 8 ECHR requires that such interference must be “in accordance with the law” and that it must be “necessary in a democratic society” in order to pursue one of the public interests listed in the provision.Footnote ⁷⁵ The ECHR primarily imposes a duty not to interfere, hence a negative obligation. Positive obligations vary on the basis of a number of factors, such as the importance of the right and the resources a public authority would need to take positive actions.Footnote ⁷⁶ In its reasoning, the Court usually examines the elements of the accordance with the law, of the identification of the legitimate aim and the “necessity” of the interference in this order; if its finds that one of these requirements is not met, it is not necessary to review compliance with the other requirements.Footnote ⁷⁷ That the interference is “necessary in a democratic society” translates into a requirement of proportionality to the legitimate aim pursued, implying a “fair balance” between the right of the individual and various public interests.Footnote ⁷⁸

The wording of Article 7 of the EU Charter of Fundamental Rights corresponds perfectly to the first paragraph of Article 8 of the ECHR.Footnote ⁷⁹ Even though this Article does not specify the proportionality test, such a test does nevertheless apply for two reasons. First, because of the general correspondence clause under Article 52, paragraph 3, of the Charter, mentioned above, which, as clearly stated in the Explanations to the Charter, also applies to Article 7.Footnote ⁸⁰ Second, according to the first paragraph of Article 52:

Therefore, proportionality is the guiding principle to assess any limitation to the right to privacy, not only because of the correspondence of Article 7 of the Charter to Article 8 of the ECHR, but also, as explicitly stated within the Charter itself—not only for privacy, but for all the rights listed in the Charter—and as a general principle of law.

The type of protection of the home and communication follows the same model in the ECHR and the EUCFR. It must be provided for in the law, and it is subject to the principle of proportionality. A significant difference, on the contrary, can be traced when comparing the type of protection that can be found in the national Constitutions, as neither the ECHR nor the EU Charter requires ex ante judicial authorization. However, the existence or the lack of such authorization can be, and has been, taken into account when assessing if a given limit to the right to privacy complies with the proportionality test, as will be seen in the following sections.

As preventive judicial control on inspections is taken into account when assessing the proportionality of public interference taking place during inspections, the rationale and function of such preventive control, as emerging from the case law of the Court of Strasbourg, need to be clarified.

First, the key rationale for the requirement of prior judicial authorization is that it limits the discretion of the executive.Footnote ⁸¹ Second, ex ante control pursues the aim of preventing an unlawful intrusion in the private sphere to take place.Footnote ⁸² Once such intrusion has taken place—for example, if personal documents have been copied—it is irreversible.Footnote ⁸³

The first purpose of preventive judicial authorization—the one of limiting discretion—can also be pursued through an authorization of the executive power. For instance, the decision of the Commission authorizing the inspectors has the purpose both of authorizing the inspectors and of circumscribing their power.^{Footnote 84} However, the idea behind the requirement of a preventive judicial control is the one that controls on such discretion should stem from a neutral authority,^{Footnote 85} an aim that cannot be guaranteed when the authorization, instead of a judicial one, is issued by an authority which is part of the EU executive.

An instrument other than the one of ex ante judicial authorization and equally capable of fulfilling the second objective—preventing an unlawful public intrusion to take place, because, for example, the inspection is based on a manifestly unlawful decision to inspect—is not easy to identify. However, obtaining a prior judicial warrant is time-consuming, and such time consumption can impair the effectiveness of the search. This makes it necessary to find instruments that, even if they cannot prevent a violation of the right of the inviolability of the home to take place, can ensure that, should an unlawful intrusion take place, an ex post full restoration can take place after the inspection. Footnote ⁸⁶

Moreover, in some cases, ex ante judicial authorization cannot be sufficient to prevent an unlawful public interference on the fundamental rights of the inspected party. Such preventive authorization, by definition, controls the content and conditions stated in the decision to inspect. It cannot prevent an unlawful interference when, for instance, the investigation activities of the inspectors go beyond the powers that are authorized in the decisions to inspect. For example, because the documents that are seized are not covered by the decision, or because the EU officers inspect the premises of a company different from the addressee of the inspection as identified in the decision to inspect. This can explain why in some cases, the Court of Strasbourg declared unlawful the intrusion that had taken place within an inspection that had been authorized ex ante by a national judge.Footnote ⁸⁷

The arguments explained above suggest: a) that limitations to ex ante judicial authorization should be attentively scrutinized; and b) that the features of a full ex post judicial review on inspections are crucial for the public interference to be lawful, even when ex ante judicial authorization is in place, as the latter can control only the decision to inspect, and not the subsequent activities.

The analysis will now turn to the case law of the Court of Luxembourg and the Court of Strasbourg, showing that they set forth different conditions that need to be met in order to compensate for the lack of ex ante judicial authorization.

D. The Limits to Ex Ante Judicial Control: Comparing the Views of the Court of Luxembourg and the Court of Strasbourg

The problem of the ex ante judicial authorization of inspections by the Commission was first raised in the 80s. In the 1989 Hoechst case,^{Footnote 88} the German firm refused to give access to the Commission inspectors, arguing that a warrant was needed. In the absence of case law on the matter from the ECHR, the Court of Justice argued that the inviolability of home did not apply to business premises.^{Footnote 89} However, the Court considered that should national laws require such authorization, national procedures should be followed.^{Footnote 90} Yet, given the necessity to maintain the unity of EU law, the control of national courts could not extend to the necessity of the measure, as this could only be assessed by the Court of Justice.^{Footnote 91}

More than ten years later, in the Roquette case in 2002,^{Footnote 92} the Court of Justice changed its approach on this point. In doing so, it was influenced by the evolution of the case law of the ECHR after the Hoechst case. In the Niemetz and Colas Est cases, the ECHR recognized that the protection of the domicile, as per Article 8 of the ECHR, is also applicable to certain activities or business or commercial premises.^{Footnote 93} However, in the Colas Est case, the Strasbourg Court also stated that the lack of ex ante prior judicial authorization was one of the elements to be taken into account in assessing whether such interference on the inviolability of the home was proportionate to the legitimate aim of public interest pursued with the investigation.Footnote ⁹⁴

In the Roquette case, the Court of Justice considered the inviolability of the home to be applicable to business premises.^{Footnote 95} It confirmed that if national jurisdictions required prior judicial authorization, such procedures should be followed. However, the Court defined the object and scope of the power of the national court responsible for issuing the authorization to conduct the inspections. This power is not full: The assessment of the necessity of the investigations rests exclusively with the Court of Justice,^{Footnote 96} while the control carried out by the national court cannot go beyond the verification of the absence of arbitrariness and the proportionality of the enforcement measures.^{Footnote 97} In order to enable the national court to carry out that assessment, the Commission “is obliged to provide said court with explanations which make it clear that the Commission possesses elements and evidence in its file that justify the suspicion of infringements of competition rules by the undertaking in question.”^{Footnote 98} This, therefore, is a significant increase in the obligation of the Commission to state reasons and, consequently, of the effectiveness of the monitoring carried out by the national court. If it should consider that it does not have sufficient information, the national court may ask the Commission for “additional information,”^{Footnote 99} but they cannot request direct access to the file.^{Footnote 100} Only in the event of insufficient information being provided, or in the absence of appropriate answers from the Commission, is the national court entitled to refuse authorization.^{Footnote 101}

The division of tasks between the national courts and the Court of Justice set forth in the Roquettes case was codified in the 2003 Regulation.^{Footnote 102} The prior authorization of the national judge—which is always necessary for inspections of places of residence, particularly when the inspected entities formally oppose the inspection if national law requires such authorization^{Footnote 103}—constitutes a first protection for the individual, against actions that are manifestly arbitrary or disproportionate. Through the broadening of the duty to give reasons for the Commission, the powers of national courts to control that the enforcement measures are not manifestly arbitrary or disproportionate have been extended compared to the Hoechst case, and, as a result, so have the guarantees for the individual. However, the powers of the national judges are still limited, as they cannot assess the necessity for investigations in relation to the aim being pursued,^{Footnote 104} and they cannot access the file,^{Footnote 105} while the full control on the lawfulness of the decision is reserved to the Court of Justice. The latter subsequently intervenes in a non-preventive way: The right to submit an appeal to the Court of Justice against the Commission’s decisions to inspect is explicitly recognized.^{Footnote 106}

The model of judicial control that emerged in the area of competition as a result of the Court of Justice case law and codified in Reg. No. 1/2003 has been extended to other sectors. Against the inspections of the ESMA and the ECB, the system of judicial protection is identical to that of the competition sector: There is a need for prior judicial approval only if this is required by national legislation; there are the same limits to the powers of control of the national court, aimed at verifying the absence of arbitrariness and proportionality; and the full control on the necessity and lawfulness of the decision is reserved to the Court of Justice.Footnote ¹⁰⁷ Therefore, the limits of the judicial protection examined with regard to the competition sector also apply in this area, and recently emerged in the first case of inspections of the ESMA against a British trade repository (TR), one of the objects of ESMA direct supervision as analyzed above.Footnote ¹⁰⁸ In this case, in line with the national regulations, the judicial authorization had been requested in advance, although the TR in question did not oppose the inspection.^{Footnote 109} Also, in the area of aviation safety, the preventive judicial authorization is necessary when national legislation requires so.Footnote ¹¹⁰ However, in this sector, preventive authorization is necessary only to enter relevant premises, land, and means of transport, and not to execute the other inspecting powers, such as those to request documents or information, and the limits to the powers of the national judge are not explicitly codified.

As far as other sectors are concerned, EU regulations do not clearly codify when ex ante judicial authorization is needed and what are the limits of such control. For EFCA’s, EU regulations provide for compliance with rules and practices of the Member States concerned.Footnote ¹¹¹ In its first formulation, also OLAF Regulation referred to the Office’s compliance with national rules in the context of external inspections.Footnote ¹¹²

The requirement to comply with the national law of the Member State regarding EFCA’s and OLAF’s external inspections can be interpreted in the sense that a preventive judicial warrant should be asked when national law requires so.Footnote ¹¹³ However, in the Sigma Orionis case, the General Court clarified that there is no obligation for OLAF inspectors to comply with national law, and in particular for a preventive warrant to be requested, unless the inspected entity formally resists the inspection.Footnote ¹¹⁴ In this way, the Court added a condition for the application of national law—the one of the formal opposition of the inspected entity—that is inspired by the provisions applying to other sectors, such as the competition one, but that was not provided for under OLAF Regulation.

Finding that the limits of application of national law to the Office’s investigative activity were not “completely clear” and with the purpose of taking into account the Sigma ruling, Footnote ¹¹⁵ the recently approved reform of OLAF Regulation establishes that only Union law shall apply to OLAF’s investigations. In contrast, national law, and in particular the prior warrant requirement, shall apply only when national officers assist OLAF and when an economic operator formally resists the inspection.Footnote ¹¹⁶ The recent change to OLAF’s Regulation further limits the scope of ex ante judicial authorization for OLAF’s inspections and strengthens the argument according to which the lawfulness of inspection powers largely depends on the scope and features of ex post review.

Moreover, the recent reform of the OLAF Regulation provides for the establishment of a “controller of procedural guarantees,” an administrative body with the task of monitoring the Office’s compliance with procedural guarantees.Footnote ¹¹⁷ However, while the first Commission proposal aimed at revising OLAF’s Regulation assigned to the Controller, inter alia, the task of authorizing inspections,Footnote ¹¹⁸ the approved text shapes the newly established Controller as an ex post mechanism to review complaints alleging infringements of procedural rules or fundamental rights.Footnote ¹¹⁹ The establishment of the Controller is significant for two reasons. First, it further reinforces a model of control in which guarantees operate ex post and not preventively, in order to avoid any type of potential obstacle to the investigation activity, as strengthening the efficiency of OLAF is one of the main objectives of the reform. Second, the establishment of the Controller as an administrative complaint mechanism, which is not an alternative to judicial remedies and that can issue recommendations that are not-binding on OLAF’s Director-General,Footnote ¹²⁰ adds a new non-judicial remedy that economic operators can use to protect their rights. The Controller works as a sector-specific complaint instrument that could be activated in addition to any other means of redress available under EU law,Footnote ¹²¹ including the general non-judicial remedy of the EU, for instance, the European Ombudsman, to whom any citizen of the EU can complain about maladministration.^{Footnote 122} Moreover, the Controller can be considered part of a general tendency in the multiplication of sector-specific administrative review bodies.^{Footnote 123} Even though administrative non-judicial instruments multiply the venues through which EU authorities can be called to give account of how they use their inspection powers, a full examination of these tools falls beyond the scope of this Article, which deals with the functioning of the principle of effective judicial protection.

What are the features of ex post judicial review on inspections so that the absence of prior authorization can be compensated? According to the case law of the ECHR and the Court of Justice, the weaknesses from the point of view of prior judicial protection can be counterbalanced for in the event of a full ex post judicial review which regards compliance with certain procedural requirements during inspections. However, the standards to assess such compensation appear stricter in the ECHR case law than in the Court of Justice.^{Footnote 124}

In the Deutsche Bahn case, the Court of Justice maintained that “the absence of prior judicial authorization may be counterbalanced by a post-inspection review covering both questions of fact and questions of law.”^{Footnote 125} In particular, the Court confirmed the argument that a lack of prior warrant is “only one of the factors borne in mind by the ECtHR when deciding whether Article 8 of the ECHR has been infringed,”Footnote ¹²⁶ and the lawfulness of inspections does not depend on prior judicial authorization. Instead, it relies on five categories of safeguards provided for by European law,Footnote ¹²⁷ namely:

The thesis, according to which the lack of prior judicial authorization might be counterbalanced through a full ex post judicial review can also be found also in the ECHR case law. Both in Heino and Delta Pekarny, the Court admitted the possibility of such compensation; yet, it argued that, when a preventive judicial authorization is lacking, the Strasbourg Court needs to be “particularly vigilant”Footnote ¹²⁹ or “double” its control on whether the interference has been proportionate.Footnote ¹³⁰ In both cases, such double control resulted in the Court of Strasbourg stating that the existing safeguards were not sufficient to counterbalance the lack of a prior warrant and that an unlawful interference under Article 8 ECHR had occurred.Footnote ¹³¹

The Strasbourg Court clarified that, in order for ex post judicial review on inspections to be full and effective, four requirements must be met.^{Footnote 132} First, the review must be both on questions of law and aspects of fact. Second, not only the decision ordering the investigation but also the activity following such decision must be subjected to judicial control. Third, ex post judicial review must be certain. Fourth, it must be within a reasonable time limit. While in Delta Pekarny the conditions for an effective ex post judicial control on inspections were examined in order to assess whether inspections complied with Article 8 ECHR, in Canal Plus and Ravòn, the compatibility with Article 6 ECHR, concerning the right to a fair trial, was taken into account. However, the same conclusions as the features for a full ex post judicial review on inspections were reached.

According to the Court of Strasbourg, the features of ex post judicial control are crucial in compensating for the lack of a prior judicial warrant. Whether the type of ex post judicial remedies for inspections of EU authorities complies with the criteria that the Court of Strasbourg considers essential for such scrutiny to be full and effective is doubtful, as the next section will show.

E. The Ex Post Judicial Control on Inspections: The Dual Model and its Shortcomings

In order to assess whether the ex post judicial control on inspections of EU authorities is full, according to the criteria of the Court of Strasbourg, inspection powers need to be distinguished, as suggested at the beginning of this analysis, into two groups. In some sectors such as competition, banking, financial, aviation, it is expressly provided that the decision to inspect can be challenged before the Court of Justice.^{Footnote 133} This happens in the areas in which the same EU administration that conducted the inspection also has the power to adopt the sanctions.Footnote ¹³⁴ In other areas, such as OLAF’s, EFCA’s, and Directorate F’s inspections, where the check conducted during the investigation can be used for administrative or penal sanctions, adopted by a separate body—whether it is an EU or a national one—the inspecting decision cannot be autonomously challenged. In this second group of cases, the lawfulness of the inspecting decision can only be challenged together with the final act. This is why there is no single system of ex post judicial control on inspections of EU authorities, but a dual one. The shortcomings in each one of the two cases are different.

The main remedy applicable in the first group of cases—based on the right of the inspected entities to plea for the annulment of the decision to inspect before the Court of Justice—emerged in the competition area, and has been extended to the banking and the financial sectors. So far, the majority of the cases concern the competition area. In three recent cases, a number of French undertakings and associations of undertakings in the food and non-food distribution sector contested some decisions to inspect alleging, inter alia, the infringement of the right to an effective remedy, guaranteed under Article 47 EUCFR and corresponding to Article 6 ECHR.Footnote ¹³⁵

The General Court, acknowledging the need to take into account the case law of ECHR according to Article 52, paragraph 2, EUCFR and the Explanations to the Charter,Footnote ¹³⁶ and in particular, the principles stated by the Court of Strasbourg in the cases Canal Plus, Ravòn, and Delta Pekarny, recognized that the right to a full and effective judicial review of inspections requires four conditions to be satisfied. The conditions require that such review, both of the facts and points of law, covers the decision ordering the investigation and the “concerned measures”—the requirement of effectiveness; the existence of a remedy that can either prevent an infringement, or, where an unlawful act has taken place, can provide for an appropriate reparation—the requirement of efficiency; the certainty of access to proceedings—the requirement of certainty; that judicial review takes place within a reasonable time—the requirement of a reasonable time. Footnote ¹³⁷

For both the requirements of effectiveness and reasonable time, the possibility to challenge, together with the decision to inspect, also the acts performed during the inspection, is crucial. In Canal Plus, Ravòn, and Delta Pekarny, the Strasbourg Court argued, on the one hand, that not only the decision ordering the investigation but also the activity following such a decision must be subjected to judicial control. On the other hand, the possibility to challenge the inspecting acts only when the sanctioning decision is taken does not fulfill the requirement of providing a judicial review within a reasonable time limit.^{Footnote 138} In arguing that the current system of remedies available under EU law in the competition sector fulfills these requirements, the General Court provided an innovative interpretation of its own case law, resulting in a partial extension of the instruments of review on inspections.

In Nexans, the General Court had considered that an action for the annulment of the acts performed during an inspection brought in the context of an action for the annulment of the decision to inspect was inadmissible and that the legality of such acts could be reviewed only in the context of an action challenging the final sanctioning decision.Footnote ¹³⁹ The only exception to this rule, first identified in the Akzo Nobel case and recalled in Nexans in order to argue that the case before the Court was different, was considered to emerge if the Commission requested to inspect documents covered by legal professional privilege.Footnote ¹⁴⁰ In Casino and Les Mousquetaires, the GC builds on this case law, arguing that, even though the inspecting acts should generally be reviewed together with the final sanctioning decision, an action against an inspecting act brought together with an action for the annulment of the inspection decision is admissible if two conditions are met. First, according to the IBM case law, the inspecting act must “measure the legal effects of which are binding on, and capable of affecting the interests of,” the applicant, “bringing about a distinct change in his legal position.”^{Footnote 141} Second, such acts must constitute the final act of a special procedure distinct from the one that is intended to permit the Commission to take a decision on the substance of the case.^{Footnote 142} In order for such a special procedure to be opened, the inspected entity must oppose the inspecting act before it takes place, raising the fact that such an act would directly affect the right to privacy of the party. In this way, the Commission is solicited to take a position, and its response, even a tacit one, through an omission, can amount to a reviewable act.^{Footnote 143}

Even though in Casino and Les Mousquetaires, the GC recognized in principle the possibility to anticipate ex post judicial review on inspecting acts—admitting that such acts can be challenged together with the inspection decision, and not with the final sanctioning act— hence potentially making judicial review on such acts more effective and taking place within a shorter—and hence more reasonable—time, the conditions set forth for this action to be admissible are extremely restrictive. In particular, the procedural conditions—for example, that the inspected party needs to formally object during the inspection, identifying specifically which documents can infringe its interest, such as was the case in Les Mousquetaires, where specific documents and mails could affect the private life of their employees^{Footnote 144}—are hard to meet, especially when unannounced inspections take place. However, even with these limitations, the position expressed in Casino and Les Mousquetaires set forth the basis for an extension of the instruments of review on inspecting acts.

As for the requirement of efficiency of judicial review, such as the existence of a remedy that can either prevent an infringement, or, where an unlawful act has taken place, can provide for an appropriate reparation, the GC has developed two lines of reasoning. As for the prevention of an infringement, in Casino, the GC argued that an interim relief under Article 278 TFEU can be activated in order to ask for the suspension of an inspecting act.^{Footnote 145} However, as the GC itself admitted, because the decision to inspect is normally notified the day the inspection is deemed to start in the competition section, a suspension can be obtained in very rare circumstances.^{Footnote 146} As for the restoration, the GC argued that the action for damages, together with the impossibility for the Commission to rely on the results of an inspection conducted on the basis of a decision declared unlawful in order to impose a sanction, fulfilled such requirement.^{Footnote 147} It was not considered that the inadmissibility of the request of the party to obtain the restitution of the documents infringing on the right to privacy of the employees^{Footnote 148} could be in contrast with the requirement to provide for a full reparation.

For the second group of cases, there is no provision that explicitly entitles the inspected entities to challenge the decision to inspect. To understand the features of judicial protection of the individual subject to inspection in the sectors of the protection of EU financial interests, as well as fisheries and food safety, it is useful to concentrate the analysis on the first one, because the Court of Justice tends to extend such principles to other areas.

As mentioned above, at the end of OLAF’s investigations, the director draws up a report, which describes the preliminary findings, provides a preliminary legal qualification and the estimated financial impact of the facts as established. This report is accompanied by disciplinary, financial, administrative, or judicial recommendations that are sent to the EU institution or competent authorities of the Member State concerned.Footnote ¹⁴⁹ Reports shall constitute admissible evidence in administrative or judicial proceedings, of criminal or non-criminal nature, before national courts or before the CJEU, according to the type of irregularity or fraud that was identified.Footnote ¹⁵⁰

The configuration of the recommendation of OLAF as non-binding has significant consequences from the point of view of subsequent judicial protection. Applying the IBM requirements, the Court has considered as non-reviewable under Article 263 TFEU,Footnote ¹⁵¹ the decision to inspect,Footnote ¹⁵² any inspecting acts,Footnote ¹⁵³ the inspection report and recommendations,Footnote ¹⁵⁴ and the transmission of information during the investigation.Footnote ¹⁵⁵ According to the Court, not only the report but also the recommendations lack legally binding effects, which could be detrimental to the individual sphere, as the authorities receiving such recommendation retain discretionary power on whether to follow such recommendations.Footnote ¹⁵⁶

Only in one case has the inspecting report been considered as a reviewable act; yet, the position taken by the Civil Service Tribunal in the Violetti case—and based on the specificity of the position of an EU officer object of an internal investigationFootnote ¹⁵⁷—was reversed by the Court.Footnote ¹⁵⁸

According to the Court, the lack of admissibility of the action for the annulment against OLAF’s inspections does not infringe the right to effective judicial protection because two judicial remedies are available to the inspected entity:Footnote ¹⁵⁹ On the one hand, an indirect challenge, and, on the other hand, an action for damages under Articles 268 and 340 TFEU. However, the Court’s position raises some criticisms, as these two remedies fall short in meeting the criteria for full judicial protection analyzed above.Footnote ¹⁶⁰

In the case of OLAF, two different types of indirect judicial review can emerge, depending on whether the final measure is adopted by the Commission or by a national authority: In the first case, the Court of Justice can be called to review such acts in the context of an action against the final measure, while, in the second case, the Court can be called upon through a preliminary question of validity under Article 267 TFEU—when and if the sanctioning measure is adopted by the national authority and in the context of a national proceeding against such a measure.

Case law in the context of indirect judicial review against a final act of the Commission shows that the Court has been avoiding calling into question the facts challenged. In the Centre de promotion de l’emploi par la micro-entreprise (CPEM) case, the applicant called into question the procedure followed by OLAF, claiming that the report contained errors of fact and that the right of defense was infringed, as, inter alia, it did not have an opportunity to submit its observations.Footnote ¹⁶¹ However, the Court, arguing that “the rights of the defence are infringed by reason of a procedural irregularity only in so far as the irregularity has a concrete effect on the ability of the undertakings concerned to defend themselves” and that “[c]onsequently, non-compliance with rules in force the purpose of which is to protect the rights of the defense can vitiate the administrative procedure only if it is shown that the latter could have had a different outcome if the rules had been observed,” did not examine the claims.Footnote ¹⁶² Even though the principle stated by the Court of Justice can be shared—for example, that a procedural irregularity should affect the right of the defense to be taken into account—the use that the Court makes of the principle in this specific case, where the applicant did not have the opportunity to be heard, hence the right of defense had been affected, appears as instrumental to avoiding to review the substance of the case.

The willingness to avoid reviewing the substance of the case can be found not only in the context of an indirect review on a final act of the Commission, but also in a preliminary ruling. In the Thomson Sales Europe SA. case, the applicant challenged the validity of the OLAF investigation. However, the Court concluded for the manifest inadmissibility, as the questions were referred without sufficient information on the factual and legislative context.Footnote ¹⁶³

The approach of the Court of Justice that emerges in the context of the two indirect remedies raises criticisms for three reasons. First, according to the Court of Strasbourg case law, judicial scrutiny on inspection should review both aspects of fact and questions of law:Footnote ¹⁶⁴ Therefore, the tendency of the Court of Luxembourg to avoid reviewing the substance of the case falls short of fulfilling this requirement. Second, both indirect remedies can be activated only if and when the final act is adopted: Therefore, it is doubtful whether they meet the requirements according to which the judicial remedy must be certain and timely.Footnote ¹⁶⁵ Third, when the remedy of the preliminary ruling is to be used because the final act is a national one, the applicant is dependent on the preliminary question. Thus, the uncertainty of the remedy depends not only on whether a sanction is adopted on the basis of the inspection, but also on whether the court would examine the claim.

As for the action for damages, it is well known that the Court has consistently stated that the right to compensation for damage depends on three requirements: The rule of law infringed must be intended to confer rights on individuals, the breach must be sufficiently serious, and the existence of a causal connection between that conduct and the damage.Footnote ¹⁶⁶ When inspections are concerned, specific problems can arise as for the assessment of each of these requirements.

More specifically, the requirement can lead to compensation only when there is a sufficiently serious breach of a rule of law intended to confer rights upon individuals; in Camos Grau, the violation of the principle of independence during OLAF’s investigation has been considered as a breach of a rule intended to confer rights on individuals.Footnote ¹⁶⁷ In Franchet & Byk, the violation of the right of the defense and the principle of the presumption of innocence were also considered as rules intended to confer rights on individuals, while, in the same case, the violation of the duty to give reasons was not considered to raise any liability for the EU institutions.Footnote ¹⁶⁸ In the Tillack case, the violation of the principle of sound administration was not, in itself, considered to confer rights upon individuals, “except where it constitutes the expression of specific rights such as the right to have affairs handled impartially, fairly and within a reasonable time, the right to be heard, the right to have access to files, or the obligation to give reasons for decisions.”Footnote ¹⁶⁹

The condition of the existence of a causal connection between that conduct and the alleged damage has also been questioned due to the lack of binding effect of inspection reports. As for OLAF’s investigations, in the Tillack case, the Court found no causal link between OLAF’s recommendations to national authorities and the harm to the reputation of the inspected party due to the discretionary power of national authorities in deciding whether to follow such recommendations.Footnote ¹⁷⁰ That the lack of binding effect of the recommendations excludes the direct causal nexus between the forwarding of information and the damage, and hence the liability of the EU institution, has also been argued by the Civil Service Tribunal in the Violetti case.Footnote ¹⁷¹

The limitations for an inspected entity to successfully file an action for damages are not exclusive to OLAF. One such example can also be found in the food safety area. In the Bowland case, the Food and Veterinary Office (FVO), a directorate within the Health and Consumer Protection Directorate-General (DG) of the Commission, whose competences have now been given to the Directorate F, inspected the firm and found levels of antibiotics in the milk it produced. The findings of FVO were set in an internal note and reflected in the DG final report of the mission conducted in the UK.Footnote ¹⁷² The national competent authority, the British Food Standards Agency (FSA), inserted the note in the rapid alert system for the notification of a direct or indirect risk to human health deriving from food. As a result, the firm had to close for ten days. Following a new audit conducted by the FSA, the UK authorities identified new corrective actions and asked the Commission to declare the milk product marketed. After the refusal of the Commission to accept this statement, as they continued to consider that the level of antibiotics in the milk products concerned was not compliant with EU law, and to change the notification in the rapid alert system accordingly, Bowland filed for damages. However, the Court of First Instance stated that, as the Commission’s action was not binding upon national authorities, a claim for damages was inadmissible.Footnote ¹⁷³

The analysis shows that in the second group of cases ex post judicial review of the Court of Justice on inspection conducted by EU authorities falls short of meeting all the features set forth in the case law of the Court of Strasbourg for such review to be considered full and effective: Namely, that such review controls both elements of law and of fact, that it checks both the decision to inspect and the inspecting activities, and that it is timely and certain.

In the case of OLAF’s, EFCA’s, and Directorate F’s inspections, neither of these requirements is met. First, the Court of Justice tends to avoid reviewing the substance of the case. Second, the availability of indirect remedies—a preliminary question of validity when and if the sanctioning measure is adopted by the national authority in the context of a national proceedings against such measure or, in the case OLAF’s report is followed by a decision of the Commission, whether there is indirect judicial review against such a final decision—is uncertain, as it depends on whether a final act will be adopted and, in the case of the preliminary ruling, on whether the Court will get to examine the claim. Third, the success of the action for damages against inspections is limited, notably because of the difficulty in proving the causal link between the inspection and the damage, as the results of the inspection do not have a binding effect.

Contrarily, in the first group of cases—which include the competition, banking, financial, and aviation sectors—the right of the inspected party to act for the annulment of the decision to inspect is recognized. The activities that are conducted on the basis of such a decision are generally to be challenged only in the context of an action for the annulment of the final act. According to the Casino and Les Mousquetaires cases, inspecting acts can be challenged together with the decision to inspect, but only if they are capable of affecting the interests of the applicant, and if the inspected party opposes the act that could impair the right to privacy during the inspection procedure so that the Commission’s reaction or omission can amount to a reviewable act. The solution according to which an inspecting act can be challenged together with the inspection decision is preferable, as judicial review would take place within a shorter, and hence more reasonable according to Strasbourg parameters, time. Even if the conditions to challenge the inspecting act together with the decision to inspect are extremely restrictive, by opening in principle this possibility, the General Court has increased the protection for the inspected individuals.

The model of judicial review existing in the first group of cases—based on the right to plea for the annulment of the decision to inspect and on the possibility, limited to the restrictive conditions mentioned above, to challenge the inspecting acts together with the decision to inspect—could be extended to inspection in all sectors.

F. Concluding Remarks

The Court of Justice argued that the lack of ex ante judicial authorization can be counterbalanced through procedural guarantees and ex post judicial control. The Strasbourg Court, however, is much stricter in admitting the possibility of such counterbalance. According to the Strasbourg Court, for ex post judicial review on inspections to be full, several conditions need to be met: a) it shall cover both questions of fact and questions of law, b) it shall permit to challenge both the inspecting decision and the inspecting acts, and c) it must be certain and within a reasonable time limit.

From the point of view of judicial protection, inspection powers of EU authorities need to be divided into two groups. In the first group—comprised of the competition, banking, financial, and aviation section—the action for annulment against the inspecting decision is explicitly provided for. Even though the GC recently argued that the current system of remedies available in the EU fulfills all the requirements set forth by the Court of Strasbourg, it is questionable whether the general rule according to which the activities that are conducted on the basis of the inspection decision are to be challenged only together with the final act comply with the condition according to which remedies should be available to challenge both the inspecting decision and the inspecting acts within a reasonable time limit. In Casino and Les Mousquetaires, however, the GC clarified that inspecting acts can be challenged together with the decision to inspect if two conditions are met: If they are capable of affecting the interests of the applicant, and if the inspected party opposes the act that could impair the right to privacy before such an act takes place, so that a special procedure is opened and the Commission’s reaction, or omission, can amount to a final and reviewable act.

In the areas of the protection of financial interests, fisheries, and food safety, the shortcomings of the model of judicial protection are more serious. First, in the lack of an explicit recognition of an action for the annulment of the decision to inspect, the Court of Justice has repeatedly stated that no inspecting activities—decision to inspect, inspection act, inspection report, recommendations following the inspection—can be directly challenged through an action for annulment. According to the Court, the lack of admissibility of the action for annulment against inspections does not infringe the right to effective judicial protection because two judicial remedies are available to the inspected entity: On the one hand, an indirect challenge when the final act is adopted, and, on the other hand, an action for damages. However, the analysis demonstrated that both remedies raise concerns. Indirect remedies—which, in the case of EFCA and Directorate F, always take the form of a preliminary question of validity, while, in the case OLAF’s recommendations are directed to EU institutions, can result in an action before the Court of Justice for the annulment of a final act of an EU institution—can be activated only if and when the final act is adopted. This is why they fall short to meet the requirement, set by the Strasbourg Court, according to which the judicial remedy must be certain and timely. As for the action for damages, in several cases, the Court of Justice has argued that, as inspection reports are not binding, no causal link between the inspection and the damage could be proved.

The right to effective judicial protection of the inspected entities vis-à-vis administrative inspections of EU authorities should be improved.

A first remedy—which draws inspiration from a model of judicial protection already existing in the EU legal system—could be to explicitly provide for an action for the annulment of the decision to inspect, like the one existing in the competition, financial, and banking areas, or in other sectors where EU authorities have the power to inspect. The fact that such a remedy also exists in the banking area—where sanctions are not always adopted by the ECB, but also by national banking authorities, according to a complex system of division of competencesFootnote ¹⁷⁴—further strengthens the argument that an action for the annulment against the decision to inspect can also be ensured in sectors where there are composite procedures and sanctions are adopted at the national level. In order to activate such action, a clearer formalization of the procedural conditions to conduct inspections is desirable; for example, a formal decision to inspect, instead of an authorization, should be introduced in the sectors where it is currently lacking.Footnote ¹⁷⁵ However, as in some cases, the Court of Justice has adopted a substantial approach, recognizing the direct effect on the right of an individual regardless of the formal qualification of an act;Footnote ¹⁷⁶ this change could also be done through a shift in the case law of the Court of Justice regarding the acts through which an EU authority orders an inspection, acts that, regardless of their formal qualification, activate an obligation of the inspected entity.

Second, it must be recalled that the system of judicial protection established in the competition, financial, and banking areas, and based on the right to challenge the decision to inspect, but not the inspecting acts, that should generally be challenged with the final sanctioning decision, is not flawless. The reason the Court of Strasbourg insists that both the decision to inspect and the inspecting acts should be challenged in a certain and timely manner—hence, not with the final sanctioning decision—is that harm of the inspected entity’s rights can occur immediately during the inspection activity, independent from the eventual adoption of a sanction and that cannot be redressed by simply forbidding the use of the evidence gathered for the adoption of the final sanction. This has long been recognized by the Court of Justice when the legal professional privilege is concerned.^{Footnote 177} With the recent cases Casino and Les Mousquetaires, in which the privacy of the employees of an undertaking was at stake as during the inspections private emails and other allegedly personal documents were copied, the General Court established a general principle that can open the path for an autonomous and timely challenge of inspecting acts, when such acts are capable of affecting the interests of the applicant. However, in order to activate such a right, the inspected entity has to oppose the inspecting act before it takes place so that a special procedure must be started.^{Footnote 178} Yet, the features of such a special procedure are not clarified. Moreover, according to the Court, the same limitations apply not only to ask for the annulment of the inspecting act, but also for a second remedy to be activated: The restitution of the documents allegedly impinging on the privacy of the employees of the undertaking was refused on the same grounds.^{Footnote 179}

This point leads to the clear connection between procedural guarantees and judicial control, a link that has been made in the case law both of the Court of Luxembourg and of the Strasbourg Court, and that is crucial for the public interference on fundamental rights to be lawful and proportionate.Footnote ¹⁸⁰ Initiatives intended to introduce a common procedure for inspections conducted by EU authorities, applicable horizontally to all sectors, were elaborated by the Research Network on EU Administrative Law (ReNEUAL)Footnote ¹⁸¹ and are at the basis of the proposal for a regulation attached to the Parliamentary Resolution of 9 June 2016.Footnote ¹⁸² It is hoped that future developments will take inspiration from these proposals, resulting in a significant improvement of the procedural framework for the inspection powers of EU authorities.
