The European Commission's work on a European code for cross-border police cooperation is gaining momentum. The idea was presented for the first time in the framework of the EU Security Strategy, which was presented in July 2020 (→ eucrim 2/2020, 71-72). As part of the roadmap to develop a corresponding legislative proposal, citizens and stakeholders now have the opportunity to comment on the project until 14 June 2021. The aim of the initiative is to simplify and modernise cooperation between competent national authorities in the area of law enforcement. The code is to merge the various existing legislative instruments and guidelines on police cooperation into a common regulation. In addition, it is considered to include selected elements from existing bilateral agreements between Member States on police cooperation in this consolidated legal act. This could include, for example, covert investigative measures on the territory of the neighbouring state, cross-border surveillance without a judicial order in urgent cases or even custodial measures on the territory of the neighbouring state. The Commission’s concrete proposal for a regulation has been announced for the fourth quarter of 2021.
