The Court also held that the disclosure of the data subject’s personal data is necessary in instances where certain rights and obligations would otherwise be inhibited.
English Summary
Facts
By a letter of 18 December 2019, registered at the Court as Case E-11/19, the Board of Appeal for Administrative Matters (BoA) made a request (in the context of appeals against decisions of the DPA of the Principality of Liechtenstein). The BoA requested for an advisory opinion in a case pending before the DPA between Adpublisher AG (a public limited company of Liechtenstein) and "J" for alleged infringement of Articles 5, 6 and 15 GDPR. The DPA upheld J’s complaint concerning the infringement of Articles 5 and 6 GDPR. Further, on its own volition, the DPA determined that there had been an infringement of Articles 7, 15 and 32 GDPR. By a separate letter of 18 December 2019, registered at the Court as Case E-12/19, the BoA made a request for an advisory opinion in a case pending before it between Adpublisher AG and "K" (for alleged infringement of Article 15 GDPR). The DPA upheld K’s complaint in part and determined that there had been an infringement of Article 15 GDPR. Adpublisher challenged both decisions before the BoA and requested that both decisions be set aside. The Court decided, pursuant to Article 39 of the Rules of Procedure, to join the cases for the purpose of the procedure and the final judgment.
Dispute
The questions examined by the court are referring to the general procedure of hearing a complaint under the GDPR and further national appellate proceedings. The first question by the referring body, is whether the proceedings under article 77 and 78(1) GDPR may be carried out without disclosing the identity of a complainant, and whether any grounds must be provided for non disclosing the identity of the complainant. The second question set by the referring body, is whether the free of charge nature of the complaint procedure under article 77 GDPR extends to subsequent proceedings before appellate bodies, or has an impact on the liability of the data subject to be ordered to pay costs.
Holding
As per the first question examined, the court the Court held that disclosing personal data of a complainant in a procedure initiated by the complainant themselves is necessary in instances where the following would otherwise be inhibited: 1. The ability to carry out obligations under the GDPR, 2. The exercise of the right to effective judicial remedy and due process.
Further, the court held that the referring body essentially asks whether the free of charge nature of the complaint procedure under Article 77 GDPR extends to proceedings before appellate bodies or has an impact on the liability of the data subject to be ordered to pay costs. The court held that the data subject cannot be made responsible for costs incurred in relation to proceedings where: 1. They have been made party to these proceedings under Article 78(1) GDPR by virtue of a data controller appealing against a supervisory authority’s decision and, 2. National law imposes this status on a data subject automatically.
Consequently, where a data subject becomes a party to proceedings under Article 78(1) GDPR after a data controller appealing against a supervisory authority’s decision, and where national law imposes this status on a data subject automatically, the data subject may not be made responsible for any costs incurred in relation to those proceedings.

JUDGMENT OF THE COURT 10 December 2020 (Regulation (EU) 2016/679 – Data protection – Right to lodge a complaint with a supervisory authority – Right to an effective judicial remedy against a supervisory authority – Anonymity – Costs incurred in appeal proceedings) In Joined Cases E-11/19 and E-12/19, REQUESTS to the Court under Article 34 of the Agreement between the EFTA States on the Establishment of a Surveillance Authority and a Court of Justice by the Liechtenstein Board of Appeal for Administrative Matters (Beschwerdekommission für Verwaltungsangelegenheiten), in cases pending before it between Adpublisher AG and J and Adpublisher AG and K, concerning the interpretation of Regulation (EU) 2016/679 of the European Parliament and of the Council of 27 April 2016 on the protection of natural persons with regard to the processing of personal data and on the free movement of such data, and repealing Directive 95/46/EC (General Data Protection Regulation), Language of the request: German. Translations of national provisions are unofficial and based on those contained in the documents of the case. – 2 – THE COURT, composed of: Páll Hreinsson, President (Judge-Rapporteur), Per Christiansen, and Bernd Hammermann, Judges, Registrar: Ólafur Jóhannes Einarsson, having considered the written observations submitted on behalf of: − Adpublisher AG (“Adpublisher”), represented by Stefan Ritter, attorney; − the Government of Liechtenstein, represented by Dr Andrea Entner-Koch, and Romina Schobel, acting as Agents; − the Government of Austria, represented by Dr Albert Posch and Dr Julia Schmoll, acting as Agents; − Ireland, represented by Marie Browne and Tony Joyce, acting as Agents; − the EFTA Surveillance Authority (“ESA”), represented by Ewa Gromnicka, Stewart Watson and Carsten Zatschler, acting as Agents; and − the European Commission (“the Commission”), represented by Friedrich Erlbacher and Herke Kranenborg, acting as Agents; having regard to the Report for the Hearing, having heard oral argument of Adpublisher, represented by Stefan Ritter; the Government of Liechtenstein, represented by Dr Andrea Entner-Koch and Romina Schobel; Ireland, represented by Tony Joyce and David Fennelly; ESA, represented by Ewa Gromnicka, Stewart Watson and Carsten Zatschler; and the Commission, represented by Friedrich Erlbacher and Herke Kranenborg; at the hearing on 16 June 2020, gives the following Judgment I Legal background EEA law 1 Regulation (EU) 2016/679 of the European Parliament and of the Council of 27 April 2016 on the protection of natural persons with regard to the processing of personal data – 3 – and on the free movement of such data, and repealing Directive 95/46/EC (General Data Protection Regulation) (“GDPR”) (OJ 2016 L 119, p. 1) was incorporated into the EEA Agreement by Decision of the EEA Joint Committee No 154/2018 of 6 July 2018 (OJ 2018 L 183, p. 23) (“the Joint Committee Decision”), and is referred to at point 5e of Annex XI (Electronic communication, audiovisual services and information society) to the EEA Agreement. Constitutional requirements were indicated by Liechtenstein and the decision entered into force on 20 July 2018. 2 Recital 7 of the GDPR reads: Those developments require a strong and more coherent data protection framework in the Union, backed by strong enforcement, given the importance of creating the trust that will allow the digital economy to develop across the internal market. Natural persons should have control of their own personal data. Legal and practical certainty for natural persons, economic operators and public authorities should be enhanced. 3 Recital 26 of the GDPR reads: The principles of data protection should apply to any information concerning an identified or identifiable natural person. Personal data which have undergone pseudonymisation, which could be attributed to a natural person by the use of additional information should be considered to be information on an identifiable natural person. To determine whether a natural person is identifiable, account should be taken of all the means reasonably likely to be used, such as singling out, either by the controller or by another person to identify the natural person directly or indirectly. To ascertain whether means are reasonably likely to be used to identify the natural person, account should be taken of all objective factors, such as the costs of and the amount of time required for identification, taking into consideration the available technology at the time of the processing and technological developments. The principles of data protection should therefore not apply to anonymous information, namely information which does not relate to an identified or identifiable natural person or to personal data rendered anonymous in such a manner that the data subject is not or no longer identifiable. This Regulation does not therefore concern the processing of such anonymous information, including for statistical or research purposes. 4 Recital 69 of the GDPR reads: Where personal data might lawfully be processed because processing is necessary for the performance of a task carried out in the public interest or in the exercise of official authority vested in the controller, or on grounds of the legitimate interests of a controller or a third party, a data subject should, nevertheless, be entitled to object to the processing of any personal data relating to his or her particular situation. It should be for the controller to demonstrate that its compelling legitimate interest overrides the interests or the fundamental rights and freedoms of the data subject. – 4 – 5 Article 4 of the GDPR, headed “Definitions”, reads, in extract: ... (1) ‘personal data’ means any information relating to an identified or identifiable natural person (‘data subject’); an identifiable natural person is one who can be identified, directly or indirectly, in particular by reference to an identifier such as a name, an identification number, location data, an online identifier or to one or more factors specific to the physical, physiological, genetic, mental, economic, cultural or social identity of that natural person; (2) ‘processing’ means any operation or set of operations which is performed onpersonal data or on setsof personal data, whether ornotby automatedmeans, such as collection, recording, organisation, structuring, storage, adaptation or alteration, retrieval, consultation, use, disclosure by transmission, dissemination or otherwise making available, alignment or combination, restriction, erasure or destruction; … (7) ‘controller’ means the natural or legal person, public authority, agency or other body which, alone or jointly with others, determines the purposes and means of the processing of personal data; where the purposes and means of such processing are determined by Union or Member State law, the controller or the specific criteria for its nomination may be provided for by Union or Member State law; … 6 Article 5 of the GDPR, headed “Principles relating to processing of personal data”, reads, in extract: 1.

The data subject shall have the right to obtain from the controller restriction of processing where one of the following applies: … (c) the controller no longer needs the personal data for the purposes of the processing, but they are required by the data subject for the establishment, exercise or defence of legal claims; … 2. Where processing has been restricted under paragraph 1, such personal data shall, with the exception of storage, only be processed with the data subject's consent or for the establishment, exercise or defence of legal claims or for the protection of the rights of another natural or legal person or for reasons of important public interest of the Union or of a Member State. ... 9 Article 21(1) of the GDPR, headed “Right to object”, reads: The data subject shall have the right to object, on grounds relating to his or her particular situation, at any time to processing of personal data concerning him or her which is based on point (e) or (f) of Article 6(1), including profiling based on those provisions. The controller shall no longer process the personal data unless the controller demonstrates compelling legitimate grounds for the processing which override the interests, rights and freedoms of the data subject or for the establishment, exercise or defence of legal claims. 10 Article 55(1) of the GDPR, headed “Competence”, reads: Each supervisory authority shall be competent for the performance of the tasks assigned to and the exercise of the powers conferred on it in accordance with this Regulation on the territory of its own Member State. – 6 – 11 Article 56(1) of the GDPR, headed “Competence of the lead supervisory authority”, reads: Without prejudice to Article 55, the supervisory authority of the main establishment or of the single establishment of the controller or processor shall be competent to act as lead supervisory authority for the cross-border processing carried out by that controller or processor in accordance with the procedure provided in Article 60. 12 Article 57 of the GDPR, headed “Tasks”, reads, in extract: 1.

The government regulates the details of the fee by ordinance. – 10 – 19 Article 20 of the Data Protection Act, headed “Legal remedies”, reads: 1) Appeals against decisions and orders of the Data Protection Authority may be lodged with the Board of Appeal for Administrative Matters within four weeks of service. 2) Appeals against decisions and orders of the Board of Appeal for Administrative Matters may be lodged with the Administrative Court within four weeks of service; the Data Protection Authority also has this right. 3) The Data Protection Authority may not deprive decisions and orders against a public body of suspensive effect. 20 Article 31(1) of the General Administrative Procedures Act (“the Liechtenstein Administrative Procedures Act”) (Landesverwaltungspflegegesetz, LR 172.020), headed “Parties” in the section “Parties and their representatives and advocates” in the first chapter “General provisions”, reads: 1) A person who approaches the administrative authority (official) with the request that it undertake or refrain from a sovereign administrative act in the legal interest of the applicant (interested party), or who as a possible subject of a public obligation or a public right is subjected to a procedure intended to determine the obliged or entitled person, or finally to whom the authority directs an order or decision as a result of a procedure is to be considered a party (intervening party, party involved, interested party, opposing party). In the case of doubt, the status as a party (beneficiary, interested party, etc.) is to be determined with due regard to the subject matter and on the basis of the applicable laws. 21 Article 35 of the Liechtenstein Administrative Procedures Act, headed “Principles for the obligation to pay costs” in the section “Costs in administrative procedures”, reads: 1) In a procedure that may only be initiated at the request of a party, such as granting a permit, initiating expropriation, concession, etc., all costs and fees of the procedure, as well as those of the other parties, shall be paid by the party initiating the procedure. 2) If a procedure is initiated by the authority ex officio, due to an unlawful situation, the costs caused by the procedure shall be borne by the party who is responsible for the unlawful situation through his own unlawful acts; if fault is not present or it is impossible to identify the person responsible, the costs shall be borne by the owner. 3) In all cases, however, each party shall bear the costs which have been caused by their wilful requests, their wilful objections to requests by the other party or other acts aimed at delaying the procedure, or by such requests that are – 11 – capable of forming the basis for an independent procedure that may only be initiated at the request of a party. 4) If a procedure aims at a decision on a claim to financial benefits, which is requested by one party against another party, the issue of the costs shall be decided according to the relevant provisions of the Code of Civil Procedure regarding the costs of litigation. 22 Article 82 of the Liechtenstein Administrative Procedures Act headed “Written copy” in the section “The conclusion procedure” reads, in extract: 1) The written copy of the decision must contain: (a) the title: decision; (b) the names of the members of the government and of the official who carried out the investigation and, if the hearing was conducted on different administrative days and by different officials, the names of the same, specifying the hearings they chaired; the designation of the parties to the procedure by first and last name, employment and place of residence, as well as the designation of the legal representatives of the parties present at the hearing, their representatives, and technical or other advocates; as well as any representatives of authorities or advisory experts or specialists; … II Facts and procedure Introduction 23 By a letter of 18 December 2019, registered at the Court as Case E-11/19 on 23 December 2019, the Board of Appeal for Administrative Matters (“the Board of Appeal”)made a request for an advisory opinion in a case pending before it between Adpublisher AG and J. By a separate letter of 18 December 2019, registered at the Court as Case E-12/19 on 23 December 2019, the Board of Appeal made a request for an advisory opinion in a case pending before it between Adpublisher AG and K. 24 The questions referred by the Board of Appeal arise in the context of appeals against decisions of the Data Protection Authority of the Principality of Liechtenstein (“the Data Protection Authority”), which have been brought before the Board of Appeal by Adpublisher, a public limited company registered under the laws of Liechtenstein. – 12 – Background 25 According to the request for an advisory opinion in Case E-11/19, the Board of Appeal has under review a challenge by Adpublisher to a decision of the Data Protection Authority, in response to a complaint brought by the data subject J for alleged infringement of Articles 5, 6 and 15 of the GDPR. Data subject J remains anonymous in the proceedings before the Board of Appeal. 26 In Case E-12/19, the Board of Appeal has under review a challenge by Adpublisher to a decision of the Data Protection Authority, in response to a complaint brought by the data subject K for alleged infringement of Article 15 of the GDPR. Data subject K also remains anonymous in the proceedings before the Board of Appeal. 27 In both cases, the original complaints were brought to the Commissioner for Data Protection for Lower Saxony, on 16 September 2018 and 18 November 2018, respectively. Both complaints questioned the sourcing and subsequent processing of personal data by Adpublisher as a data controller pursuant to Article 4(7) of the GDPR, in the context of online marketing. 28 Adpublisher is a public limited company under Liechtenstein law, with a registered office in Liechtenstein. Given the cross-border character of the complaints, pursuant to Article 56 of the GDPR, the Data Protection Authority was designated to deal with the cases as the lead supervisory authority. 29 The Data Protection Authority upheld J’s complaint concerning the infringement of Articles 5 and 6 of the GDPR. Further, of its own motion, the Data Protection Authority determined that there had been an infringement of Articles 7, 15 and 32 of the GDPR. In addition, the Data Protection Authority upheld K’s complaint in part and determined that there had been an infringement of Article 15 of the GDPR. The proceedings before the Board of Appeal 30 Adpublisher challenged both decisions before the Board of Appeal and requested that both decisions be set aside. 31 In its requests for advisory opinions, the Board of Appeal notes, first, that, pursuant to Article 31(1) of the Liechtenstein Administrative Procedures Act, in the context of the cases before it, each data subject is regarded as a party to the respective appeal procedure. Pursuant to point (b) of Article 82(1) of the Liechtenstein Administrative Procedures Act, the written version of decisions taken by the Board of Appeal must include the designation of the parties to the procedure stating, inter alia, their first and last names, profession and place of residence. 32 According to the Board of Appeal, the question, therefore, arises whether it results from the GDPR or another provision of EEA law, that an anonymisation of the complainant is permissible. Furthermore, the subsequent question arises as to whether particular reasons for the anonymisation must be prima facie established. – 13 – 33 Second, the Board of Appeal notes in its requests that Article 57(3) of the GDPR provides that the performance of the tasks of each supervisory authority shall be free of charge for the data subject. Procedures before the Board of Appeal are governed by the Liechtenstein Administrative Procedures Act. While Article 35 of the Liechtenstein Administrative Procedures Act provides for different possibilities for the determination of costs, no express provision is made for a complaint procedure brought in accordance with Article 77 of the GDPR to be free of charge for the data subject. Hence, if a data subject brings a complaint to a data protection authority in accordance with Article 57(3) of the GDPR and the decision of the data protection authority is challenged on appeal, as a matter of Liechtenstein law, the data subject may come under an obligation to reimburse costs. 34 Lastly, the Board of Appeal notes that the question arises regarding how to proceed if an anonymised complaint procedure is permissible and an obligation to reimburse costs is not precluded. 35 On this basis, the Board of Appeal decided to stay both proceedings and make requests to the Court for advisory opinions pursuant to Article 34 of the Agreement between the EFTA States on the Establishment of a Surveillance Authority and a Court of Justice. The Board of Appeal has in both requests asked the following questions: 1. Does it follow from Regulation (EU) 2016/679 of the European Parliament and of the Council of 27 April 2016 on the protection of natural persons with regard to the processing of personal data and on the free movement of such data, and repealing Directive 95/46/EC (General Data Protection Regulation, GDPR) or from another provision of EEA law that an adversarial general procedure to hear a complaint may be carried out under the GDPR without disclosing the name and address of the complainant in the complaint procedure? If the answer to the question is in the affirmative: Is it necessary in this case that a legitimate reason for the anonymisation is at least prima facie established or are no reasons required for the anonymisation? 2. Must a Member State ensure in its national procedural law that in a procedure to hear a complaint in accordance with Article 77 of the GDPR all further national appellate bodies are free of charge for the data subject and that the data subject may also not be ordered to reimburse the costs? 3. If Question 1 is answered in the affirmative and Question 2 is answered in the negative, in other words, an adversarial general procedure to hear a complaint may be carried out under the GDPR without identifying the name and address of the complainant in the complaint procedure and national procedural law is not required to ensure that in a procedure to hear a complaint in accordance with Article 77 of the GDPR all further national appellate bodies are free of charge for the data subject, the question arises how a decision – 14 – resulting from a complaint procedure and ordering the data subject – who remains, however, anonymous – can be effected to reimburse the costs? 36 Both requests for advisory opinions were registered at the Court on 23 December 2019. On 22 January 2020, the Court informed the parties that it was considering joining the two cases. No objections were raised and, consequently, the Court decided, pursuant to Article 39 of the Rules of Procedure (“RoP”), to join Cases E-11/19 and E-12/19 for the purpose of the procedure and the final judgment. The parties were informed of this decision on 5 February 2020. 37 By a letter dated 25 March 2020, the Court made a request for clarification to the Board of Appeal under Article 96(4) RoP concerning the facts set out in the orders for reference. The Board of Appeal replied to these questions by two letters dated 20 April and 4 May 2020. 38 On 14 April 2020, the Court prescribed measures of organization of procedure pursuant to Article 49(1) and in accordance with point (a) of Article 49(3) RoP. The measures of organization of procedure invited those who are entitled to submit statements or observations to supplement the written procedure on the following matters by 14 May 2020: To recall, if necessary, by way of a highly condensed summary, the positions taken by their submissions, with emphasis on the essential submission in support of the written arguments presented; to submit any new arguments prompted by recent events occurring after the close of the written procedure which, for that reason, could not be set out in the pleadings; to explain and expound the more complex points and highlight the most important points; to reply briefly to the main arguments set out in other written observations. 39 Responses to the measures of organization of procedure were received from Adpublisher, the Data Protection Authority, the Government of Liechtenstein, Ireland, ESA and the Commission. These responses are mentioned or discussed hereinafter only insofar as is necessary for the reasoning of the Court. 40 Reference is made to the Report for the Hearing for a fuller account of the legal framework, the facts, the procedure and the written observations submitted to the Court, which are mentioned or discussed hereinafter only insofar as is necessary for the reasoning of the Court. – 15 – III Answer of the Court Preliminary remarks 41 The questions, as they have been formulated by the referring body, concern an adversarial general procedure to hear a complaint under the GDPR and further national appellate proceedings. In the present case, the supervisory authority has already granted “anonymisation” of the complainantsduring proceedings under Article 77 of the GDPR, and “anonymisation” is also sought in the proceedings within the scope of Article 78 of the GDPR. Question 1 42 By its first question, the referring body asks, in essence, whether it follows from the provisions of the GDPR or any other provision of EEA law, that the proceedings under Articles 77 and 78(1) may be carried out without disclosing the identity of a complainant; and whether any grounds must be provided for not disclosing the identity of the complainant. 43 The Court understands that the referring body addresses the refusal to disclose personal data relating to the complainants as “anonymisation”. Recital 26 of the GDPR clarifies that anonymous information does not fall within the scope of the GDPR. The GDPR does not explicitly define “anonymisation”, but recital 26 refers to data “… rendered anonymous in such a manner that the data subject is not or no longer identifiable”. Since the Court is not able to determine the precise nature of the data processing in question on the basis of the requests, the Court refers to disclosure as disclosure to the data controller of the complainants’ personal data within the meaning of Article 4(2) in the course of proceedings under both Articles 77 and 78 of the GDPR. Article 4(2) refers to disclosure as a type of data processing by which personal data is made available by transmission, dissemination or other means. 44 Neither Article 77 nor Article 78(1) of the GDPR lays down specific rules concerning the disclosure of the identity of the complainants, or whether requests for disclosure should be granted. 45 The Court recalls that, under the principle of procedural autonomy, matters concerning the regulation of the procedure governing complaints and the proceedings arising therefrom are to be regulated at national level, provided the requirements of equivalence and effectiveness are respected. This means that the rules must not render practically impossible or excessively difficult the exercise of rights conferred by EEA law (see Case E-6/17 Fjarskipti [2018] EFTA Ct. Rep. 78, paragraph 31). 46 The Court notes that the main principle of the GDPR is that any data processing, including disclosure of data, can only take place if data processing is lawful in accordance with Articles 5 and 6 of the GDPR. Furthermore, according to point (c) of Article 5(1), personal data shall be adequate, relevant and limited to what is necessary in relation to the purposes for which they are processed. – 16 – 47 The Court notes that, at the moment of receiving a complaint from an identified or identifiable natural person, the supervisory authority becomes the controller of any processing of the complainant’s personal data necessary to handle the complaint. Similarly, the referring body, in a case such as that in question, becomes a controller of any processing of personal data when it receives an appeal against a decision. The supervisory authority and appellate body’s processing of personal data for handling a complaint or appeal will generally have a lawful basis and be necessary in the public interest pursuant to point (e) of Article 6(1) of the GDPR. 48 If a data subject has objected to the data processing, it follows from Article 21(1) of the GDPR that compelling legitimate grounds for the processing, which override the interests, rights and freedoms of the data subject or for the establishment, exercise or defence of legal claims must be demonstrated (compare also point (c) of Article 18(1), Article 18(2) and recital 69 of the GDPR). The assessment of whether it is necessary to disclose the identity of complainants to other parties must strike a balance between the data subject’s interests, rights and freedoms, and the parties’ rights of defence and fair procedures. 49 It should be recalled that Article 58(4) of the GDPR prescribes that the exercise of the powers conferred on the supervisory authority shall be subject to appropriate procedural safeguards, including effective judicial remedy and due process, set out in EEA law and national law. This express guarantee of due process requires that a decision to disclose the identity of the complainants should generally be made if withholding the identity of the data subject would hinder the data controller from establishing the exact circumstances of the case, and consequently inhibit the possibility of an effective exercise of its right to a judicial remedy. 50 According to Article 1(i) of the Joint Committee Decision, the words “in accordance with the Charter” in Article 58(4) of the GDPR shall not apply as regards the EFTA States. However, fundamental rights form part of the general principles of EEA law. The Court has held that the provisions of the European Convention on Human Rights (“ECHR”) and the judgments of the European Court of Human Rights are important sources for determining the scope of these fundamental rights (see Case E-14/15 Holship [2016] EFTA Ct. Rep. 240, paragraph 123). Effective judicial protection including the right to a fair trial, which is a general principle of EEA law, provides for a level of protection equivalent to Article 6(1) of the ECHR (see Case E-15/10 Posten Norge AS [2012] EFTA Ct. Rep. 246, paragraph 86 and case law cited; and Case E-4/11 Arnulf Clauder [2011] EFTA Ct. Rep. 216, paragraph 49 and case law cited). This necessarily includes the right to mount an effective defence. Consequently, if a refusal to disclose personal data would impair the data controller’s ability to exercise its right of defence, then the individual’s identity must be disclosed. 51 As noted by Ireland, the Commission and ESA, the effective functioning of data protection compliance under the GDPR may require disclosing the complainant’s personal data to the data controller. This would be the case, inter alia, when the data subject, in accordance with point (c) of Article 58(2) of the GDPR, requests to exercise his or her rights or alleges infringement of his or her rights by the controller. Acting on – 17 – this request, a supervisory authority may need to disclose the identity of a complainant to the controller to enable the latter to fulfil the order. In turn, the supervisory authority’s exercise of its powers, in accordance with, inter alia, points (e) to (g) and (j) of Article 58(2) of the GDPR, may necessitate disclosing the identity of the complainants to the controller. 52 On the other hand, disclosing complainants’ identities may not be necessary for the effective exercise of the right of defence where the investigation or decision concerns standardised and equal data processing for an unspecified number of data subjects, or where the investigation and decision is based on several similar complaints. 53 Further, a complaint lodged by a data subject pursuant to Article 77 of the GDPR must be qualified in the sense that the alleged infringement of the GDPR relates to the processing of personal data of that data subject. A data subject has certain procedural rights concerning the complaint in accordance with Article 77(2) of the GDPR. The supervisory authority must inform the subject of the progress and the outcome of the complaint, including the possibility of a judicial remedy pursuant to Article 78 of the GDPR. To effectively satisfy this obligation, the identity of the data subject must be known to the supervisory authority. 54 It is for the referring body to determine whether the nature of the case at hand is such as to require disclosure of the identity of the data subject to the controller in light of those requirements. 55 Against this background, the answer to the first question must be that disclosure of a complainant’s personal data during proceedings based on a complaint lodged under Article 77 of the GDPR, or proceedings based on Article 78(1) of the GDPR, is not precluded by the GDPR or any other provision of EEA law. The question of non- disclosure of a complainant’s personal data must be examined in the light of the principles for processing personal data under Articles 5 and 6 of the GDPR. Non- disclosure should not be granted if it would inhibit the performance of the obligations provided in the GDPR, or the exercise of the right to effective judicial remedy and due process as set out in Article 58(4) of the GDPR and under the fundamental right to an effective judicial remedy. Question 2 56 By its second question, the referring body essentially asks whether the free of charge nature of the complaint procedure under Article 77 of the GDPR extends to subsequent proceedings before appellate bodies or has an impact on the liability of the data subject to be ordered to pay costs. 57 Article 77 of the GDPR sets out the right to lodge a complaint with a supervisory authority. Article 57(3) provides that the tasks of the supervisory authority, including the handling of complaints, are to be free of charge for the data subject. In order to handle complaints lodged, Article 58(1) confers extensive investigative powers on the supervisory authority. If the supervisory authority considers that requirements of the – 18 – GDPR have not been complied with, Article 58(2) lays down the various corrective powers the supervisory authority may adopt (compare the judgment in Facebook Ireland and Schrems, C-311/18, EU:C:2020:559, paragraph 111). 58 While Article 57(3) of the GDPR is limited to the performance of the tasks of the supervisory authority, no other provision of the GDPR specifically addresses a legal costs scheme. In particular, costs are not regulated in relation to proceedings under Article 78(1) of the GDPR. The Court notes that Article 58(4) and Article 78 of the GDPR give expression to the right to an effective judicial remedy. Under the principle of procedural autonomy, the implementation of the judicial remedy is left to the national legal order, provided that principles of equivalence and effectiveness are respected. 59 However, Article 78(3) of the GDPR provides that proceedings against a supervisory authority shall be brought before the courts of the EEA State where the supervisory authority is established. This provision presupposes that the supervisory authority assumes the position of a defendant, defending its own decision when that decision is challenged. However, in the absence of any specific provisions to that effect, Article 78(3) cannot be interpreted as precluding the possibility that other entities, e.g. complainants, may also be become parties to such proceedings under the procedural law of the EEA State in question. In the present case, as observed by the Commission and as is apparent from the request, by lodging their complaints with the supervisory authority under Article 77, the complainants were accorded the status of defendants when the controller lodged an appeal against the decision of the supervisory authority under Article 78. It also appears that the status of the complainants before the referring body is one of defending the decision of the supervisory authority, including issues which were not within the scope of their complaints. 60 It is important to note that, under point (h) of Article 57(1) of the GDPR, the supervisory authority has the power to engage in investigations of its own initiative. This provides that the supervisory authority may, in relation to its examination of the complaint, decide on different claims or subject-matter in comparison with those raised by the data subject in his or her complaint before the supervisory authority. The effectiveness of the complaint procedure requires that the supervisory authority is not limited in its investigation by how the complainant has framed the relevant points of law in his or her complaint. 61 In a situation in which the data subject does not initiate proceedings under Article 78(1) of the GDPR, but nevertheless is accorded the status of a defendant in those proceedings, the potential order to reimburse costs would have an effect equivalent to charging fees for the tasks of a supervisory authority. 62 Such an obligation to reimburse costs is not in line with the right to lodge a complaint free of charge under Article 77(1) and 57(3) of the GDPR and moreover runs contrary to the purpose of the GDPR to create a strong enforcement mechanism and enhance legal and practical certainty for data subjects (see recital 7 of the GDPR). The prospect of costs reimbursement constitutes a disincentive to lodge a complaint before a supervisory authority. Thus, the Court finds that such a set-up undermines the scope of – 19 – protection guaranteed by the provisions of the GDPR referred to above, and the exercise of rights conferred by EEA law would be rendered excessively difficult, in breach of those provisions of the GDPR. 63 Article 3 EEA requires EEA States to take all measures necessary to guarantee the application and effectiveness of EEA law. It is inherent in the objectives of the EEA Agreement that national courts are bound, as far as possible, to interpret national law in conformity with EEA law. Consequently, they must, as far as possible, apply the methods of interpretation recognised by national law in order to achieve the result sought by the relevant rule of EEA law (see Case E-25/13 Gunnar Engilbertsson v Íslandsbanki hf. [2014] EFTA Ct. Rep. 524, paragraph 159 and case law cited). 64 In light of the foregoing, the Court finds that the answer to the second question must be that it follows from Articles 77(1) and 57(3) of the GDPR that where a data subject becomes a party to proceedings under Article 78(1) of the GDPR as a result of a data controller appealing against a supervisory authority’s decision, and where national law imposes this status on a data subject automatically, the data subject may not be made responsible for any costs incurred in relation to those proceedings. 65 In these circumstances, there is no need to answer the third question referred to the Court. IV Costs 66 The costs incurred by the Government of Liechtenstein, the Government of Austria, Ireland, ESA and the Commission, which have submitted observations to the Court, are not recoverable. Since these proceedings are a step in the proceedings pending before the national court, any decision on costs for the parties to those proceedings is a matter for that court. – 20 – On those grounds, THE COURT in answer to the questions referred to it by the Liechtenstein Board of Appeal for Administrative Matters hereby gives the following Advisory Opinion: 1. Disclosure of a complainant’s personal data during proceedings based on a complaint lodged under Article 77 of Regulation (EU) 2016/679 of the European Parliament and of the Council of 27 April 2016 on the protection of natural persons with regard to the processing of personal data and on the free movement of such data, or proceedings based on Article 78(1) of that regulation, is not precluded by that regulation or any other provision of EEA law. The question of non-disclosure of a complainant’s personal data must be examined in the light of the principles for processing personal data under Articles 5 and 6 of Regulation (EU) 2016/679. Non-disclosure should not be granted if it would inhibit the performance of the obligations provided in Regulation (EU) 2016/679, or the exercise of the right to effective judicial remedy and due process as set out in Article 58(4) and under the fundamental right to an effective judicial remedy. 2. It follows from Articles 77(1) and 57(3) of Regulation (EU) 2016/679 that where a data subject becomes a party to proceedings under Article 78(1) as a result of a data controller appealing against a supervisory authority’s decision, and where national law imposes this status on a data subject automatically, the data subject may not be made responsible for any costs incurred in relation to those proceedings.
