The ECBA Cybercrime Working Group proposes to launch a project on the harmonisation of national rules on the admissibility of digital evidence in criminal proceedings.
Current practice shows major divergence across Member States: while some systems provide for strict exclusionary rules, others, such as Germany, lack enforceable remedies against unlawfully obtained evidence, meaning objections are often only decided at cassation level and exclusion is extremely rare. The handling of large-scale encrypted communications investigations, such as Sky ECC and EncroChat, illustrates these discrepancies: courts across Europe have taken markedly different positions on whether and how such data may be used in criminal proceedings.
Against this background, and in light of the Commission’s stated interest in common standards, the Working Group proposes to develop minimum EU-wide rules governing the collection and admissibility of digital evidence and effective mechanisms to enforce prohibitions on its use. Such standards are essential to ensure proportionality, legal certainty, and the protection of fundamental rights in an increasingly digital justice environment.
