Cinneadh i gcás 233/2021/OAM ar an gcaoi ar dhéileáil an Ghníomhaireacht Eorpach um an nGarda Teorann agus Cósta (Frontex) le hiarratas ar rochtain phoiblí ar dhoiciméid a bhaineann le sonraí rianaithe árthaí a úsáidtear in oibríochtaí muirí de chuid Frontex

Bhain an cás le diúltú ón Ghníomhaireacht Eorpach um an nGarda Teorann agus Cósta (Frontex) rochtain phoiblí a dheonú ar shonraí rianaithe roinnt árthach a úsáideadh ina hoibríochtaí muirí sa Mhuir Aeigéach.D'iarr an gearánach rochtain ar chineálacha sonracha sonraí maidir le suíomh na n-árthach.Shainaithin Frontex roinnt doiciméad ar dtús ina raibh faisnéis faoi shuíomh ach dhiúltaigh sé rochtain phoiblí a dheonú ar an bhforas go mbainfeadh sé sin an bonn de leas an phobail maidir le slándáil phoiblí.Ina fhreagra deiridh, dúirt Frontex nach raibh aon doiciméid ina sheilbh ina raibh na sonraí sonracha a iarradh.

D'fhiosraigh an tOmbudsman an cheist agus dhearbhaigh sí gur fíor nach raibh cáipéisí ag Frontex ina raibh na sonraí sonracha a iarradh.Mar sin féin, rinne sí measúnú ar an seasamh substainteach a leag Frontex amach maidir le doiciméid ina raibh sonraí cosúla, i measc sonraí eile maidir le suímh árthaí, agus fuair sí go raibh cúis mhaith leis an diúltú.

D'iarr an tOmbudsman ar Frontex cur chuige comhsheasmhach a chinntiú agus iad ag freagairt d'iarratais ar rochtain phoiblí ar dhoiciméid.Go háirithe, ba cheart go mbeadh Frontex dícheallach maidir le fíorú na ndoiciméad atá ina sheilbh agus mínithe cuimsitheacha a thairiscint d’iarratasóirí.


Background to the complaint

1. The European Border and Coast Guard Agency (Frontex) is an EU agency tasked with assisting Member States in monitoring the EU’s external borders. A Member State may request Frontex to launch a joint operation in which other Member States can participate and provide technical equipment (for example vessels, aircraft, vehicles) or staff.[1] For several years, Frontex has been supporting Greece in the context of ‘Joint Operation Poseidon’ covering the area of the Greek sea borders with Turkey and the Greek islands - mainly the Aegean Sea. Operation Poseidon involves border control, search and rescue, registration and identification, as well as coast guard functions and prevention of cross-border crime.[2]

2. The complainant is a Member of the European Parliament. On 29 September 2020, she asked Frontex for public access to documents[3] containing data regarding specific vessels used in Frontex maritime operations. Specifically, the complainant requested “the Automatic Identification System data (AIS-data)[[4]] and Long Range and Identification Tracking data (LRIT-data)[[5]] of the following vessels used by FRONTEX since March 2020 until present day in the Aegean Sea.” The complainant then listed 16 vessels, for which she requested the data.

3. In November 2020, Frontex replied and explained that for the 16th vessel listed by the complainant no documents were identified. For the remaining 15 vessels, “documents mention the pieces of information sought by [the complainant] only in the [sic] passing”. Frontex did not list those documents and refused access, arguing that disclosure would undermine the protection of the public interest as regards public security as well as the protection of privacy and the integrity of the individual.[6]

4. In December 2020, the complainant asked Frontex to review its decision (by making a so-called ‘confirmatory application’).

5. In January 2021, Frontex replied, stating that it stands by the arguments presented in its initial reply. However, as part of its review of its initial position, it concluded that “no documents containing AIS and/or LRIT data for any of the vessels [the complainant] mentioned can be retrieved.”

6. In February 2021, the complainant turned to the Ombudsman.

The inquiry

7. The Ombudsman opened an inquiry into how Frontex dealt with the request for public access concerning the tracking data of the respective vessels used in Frontex maritime operations.[7]

8. In the course of the inquiry, the Ombudsman received additional information from Frontex on its handling of the complainant’s request as well as extracts from internal correspondence regarding the preparation of the replies. The Ombudsman’s inquiry team also inspected one ‘Technical equipment mission report’, as a sample of the documents identified by Frontex in its initial reply.

Arguments presented to the Ombudsman

By the complainant

9. The complainant argued that she was not interested in receiving personal data. Therefore, she asked Frontex to prepare a document containing the requested information without including personal data – if necessary by extracting it from a database by using existing search tools.[8]

10. The complainant contended that Frontex had not explained, as established by case-law,[9] how disclosing the requested information would ‘specifically and actually’ undermine the public interest as regards public security. Also, she contended that tracking information from the past, as had been requested, could not undermine the protection of the public interest as regards public security since it could not be used by traffickers with respect to vessels in the present.

11. Finally, the complainant disapproved of the way Frontex had handled her request, notably the fact that in its final assessment, Frontex argued that it did not hold any documents containing the requested data, while in its initial reply it had identified such documents.

By Frontex

12. According to the explanations provided by Frontex in its initial reply, disclosure of the documents identified would undermine the protection of the public interest as regards public security. The documents in question included the information sought by the complainant only in passing. However, they included “detailed information on the technical equipment deployed”. If traffickers were to gain hold of such information, along with the location of the vessels, they could avoid controls and endanger the vessels and their crew. The documents also included personal data whose release would undermine the protection of privacy and the integrity of the individual.

13. In its reply to the request for review, Frontex argued that it did not hold any documents containing the specific data requested by the complainant, namely AIS- and LRIT-data. Frontex explained that AIS systems operated on a radio communication frequency and sent radio messages that included, among others, the vessel’s positions. AIS data, such as these radio messages, were stored in the AIS device itself in the respective vessel as well as in coastal stations and regional vessel traffic control systems. As such, they were not received or stored by Frontex itself. Similarly, Frontex did not itself receive or store LRIT-data.

14. In the additional information transmitted to the Ombudsman, Frontex explained that the documents identified in its initial reply were ‘technical equipment mission reports‘ which, among others, contained positioning data of the concerned vessels. However, positioning data were not technically the same data as the specifically requested AIS- and LRIT-data. As such, Frontex’s assessment in its confirmatory reply differed from its initial reply. In any case, the reports were sensitive and their disclosure would undermine the protection of the public interest as regards public security.

The Ombudsman's assessment

15. The right of public access to documents applies only to documents in the possession of the institution concerned.[10]

16. In this case, Frontex, in its final reply, refused to give public access on the grounds that it does not hold any documents that would fall within the scope of the complainant’s request.

17. On the basis of the inquiry team’s inspection, as well as Frontex’s explanations, the Ombudsman does not have reason to doubt that Frontex does not hold documents containing the specific data requested by the complainant, namely AIS- and LRIT-data. As such, the Ombudsman does not identify maladministration as regards Frontex’s final position on the public access request.

18. That having been said, Frontex stated in its initial reply and acknowledged during the inquiry, that it does possess documents containing positioning data, other than AIS- and LRIT-data, with respect to 15 vessels referenced by the complainant. Therefore, the Ombudsman considers it helpful to review Frontex’s refusal to provide access to those documents.

19. The Ombudsman understands that, after each patrolling activity, assets (for example vessels, aircraft, vehicles) participating in the joint operations coordinated by Frontex have to fill in a ‘technical equipment mission report’, which includes the track followed. The documents identified by Frontex at the initial stage were ‘technical equipment mission reports’ for the 15 vessels. According to Frontex, there are around 15-25 such reports daily.

20. Frontex has argued that the disclosure of these documents would undermine the public interest as regards public security. The EU courts have found that, in general, the EU institutions enjoy wide discretion when determining whether disclosing certain information could pose a risk in that regard.[11] Any substantive review of such a decision must therefore be limited to examining whether there has been an obvious error in the institution’s assessment.

21. The General Court has acknowledged, in a similar case of a refusal by Frontex to disclose information which could lead to vessel positioning data being ascertained, that if traffickers knew the location of vessels, they would have the information needed to avoid the controls aimed at preventing unlawful border access or to attack the vessels.[12] According to the same judgment, this was the case even if the data sought on the location of vessels concerned periods in the past.[13]

22. In this case, the complainant made the access request on 29 September 2020 asking for data relating to the period between 1 March 2020 and 29 September 2020. While the time period for which the data was requested had expired, the Joint Operation Poseidon 2020 was still ongoing at the time of the request.

23. In light of this, the Ombudsman finds that Frontex’s explanation, namely that giving public access to the positioning data of the vessels constitutes a significant risk to achieving its operational mandate and as such to the security of the vessels and their crew, is plausible.

24. The public security exception which Frontex relied upon is absolute. This means that Frontex did not need to assess whether there was an overriding public interest in the disclosure of the documents.

25. Taking all the arguments into account, the Ombudsman considers that Frontex’s position that disclosing documents containing tracking data of vessels used in its maritime operations could undermine the protection of the public interest as regards public security is reasonable.[14]

26. However, the Ombudsman suggests that in the future, Frontex ensure a consistent approach when replying to requests for public access to documents. In particular, Frontex should be diligent in verifying what documents are in its possession. In addition, Frontex should assist applicants in their requests. In this case, Frontex could have provided clearer explanations to the complainant on the documents which it does hold that are similar to those requested, even if those documents were likely to be covered by relevant exceptions to public access.


Based on the inquiry, the Ombudsman closes this case with the following conclusion:

There was no maladministration by Frontex.

The complainant and Frontex will be informed of this decision.
