The case concerns the legality of Europol’s and Eurojust’s involvement in the establishment and operation of a Joint Investigation Team (JIT) between Belgium, France, and the Netherlands, formalised on 13 December 2019, and their role in the collection, processing, analysis, and exchange of encrypted communication data from the Sky ECC platform. The applicant challenges the legality of these actions on multiple grounds, including violations of EU data protection law, the Charter of Fundamental Rights, the European Convention on Human Rights (ECHR), and the International Covenant on Civil and Political Rights (ICCPR). He claims that the actions lacked proportionality and necessity, failed to ensure the legality and usability of evidence, led to double prosecution (in the Netherlands and Serbia), and lacked sufficient safeguards for the protection of personal data. The applicant seeks annulment of the measures, a declaration of inapplicability, and compensation of EUR 50,000.
