3 preliminary rulingsJudgment of 17 Jun 2021, C-597/19 (M.I.C.M. Mircom International Content Management & Consulting) 
Point (f) of subparagraph 1 of Article 6(1) 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), read in conjunction with Article 15(1) of Directive 2002/58/EC of the European Parliament and of the Council of 12 July 2002 concerning the processing of personal data and the protection of privacy in the electronic communications sector (Directive on privacy and electronic communications), as amended by Directive 2009/136/EC of the European Parliament and of the Council of 25 November 2009, must be interpreted as meaning that it precludes in principle, neither the systematic recording, by the holder of intellectual property rights as well as by a third party on his or her behalf, of IP addresses of users of peer-to-peer networks whose internet connections have allegedly been used in infringing activities, nor the communication of the names and of the postal addresses of those users to that rightholder or to a third party in order to enable it to bring a claim for damages before a civil court for prejudice allegedly caused by those users, provided, however, that the initiatives and requests to that effect of that rightholder or of such a third party are justified, proportionate and not abusive and have their legal basis in a national legislative measure, within the meaning of Article 15(1) of Directive 2002/58, which limits the scope of the rules laid down in Articles 5 and 6 of that directive, as amended.
Judgment of 6 Oct 2020, C-520/18 (Ordre des barreaux francophones and germanophone and Others)
A national court may not apply a provision of national law empowering it to limit the temporal effects of a declaration of illegality, which it is bound to make under that law, in respect of national legislation imposing on providers of electronic communications services – with a view to, inter alia, safeguarding national security and combating crime – an obligation requiring the general and indiscriminate retention of traffic and location data that is incompatible with Article 15(1) of Directive 2002/58, as amended by Directive 2009/136, read in the light of Articles 7, 8 and 11 and Article 52(1) of the Charter of Fundamental Rights. Article 15(1), interpreted in the light of the principle of effectiveness, requires national criminal courts to disregard information and evidence obtained by means of the general and indiscriminate retention of traffic and location data in breach of EU law, in the context of criminal proceedings against persons suspected of having committed criminal offences, where those persons are not in a position to comment effectively on that information and that evidence and they pertain to a field of which the judges have no knowledge and are likely to have a preponderant influence on the findings of fact.
Judgment of 2 Oct 2018, C-207/16 (Ministerio Fiscal)
Article 15(1) of Directive 2002/58/EC of the European Parliament and of the Council of 12 July 2002 concerning the processing of personal data and the protection of privacy in the electronic communications sector (Directive on privacy and electronic communications), as amended by Directive 2009/136/EC of the European Parliament and of the Council of 25 November 2009, read in the light of Articles 7 and 8 of the Charter of Fundamental Rights of the European Union, must be interpreted as meaning that the access of public authorities to data for the purpose of identifying the owners of SIM cards activated with a stolen mobile telephone, such as the surnames, forenames and, if need be, addresses of the owners, entails interference with their fundamental rights, enshrined in those articles of the Charter of Fundamental Rights, which is not sufficiently serious to entail that access being limited, in the area of prevention, investigation, detection and prosecution of criminal offences, to the objective of fighting serious crime.
