The need to protect the confidentiality of journalistic sources is a well-established principle, crucial for the exercise of the freedom of expression. At the same time, in many countries there is a growing trend to empower law enforcement and intelligence agencies with more surveillance competences. Regrettably this is not always accompanied by effective guarantees for journalistic secrecy. As a result the surveillance of electronic communication has been considered one of the leading contemporary threats to the free media. In the course of the project “Protecting journalistic sources in the age of digital surveillance” researchers from Poland, Bulgaria and Romania are analyzing legal frameworks and cases that occurred in their countries and are related to the surveillance of journalists, in order to identify adequate legal standards and possible remedies for the victims. The aim of the presentation will be to give an overview of the issues which lie at the heart of the project, as well as present the methods and initial results.
