Using the Leiden Guidelines to address key issues in digitally derived evidence

The global developments have shown one thing clearly: there is a lack of guidance and clarity when it comes to using DDE in the courtroom. Due to the fast evolution of digital technology and the (often, by design) slow evolution of courts and tribunals, the treatment of DDE within and between national and international accountability fora suffers from an absence of uniformity at best, and a lack of any useful guidance at worst. The Leiden Guidelines on the Use of Digitally Derived Evidence in International Criminal Courts and Tribunals (“ The Leiden Guidelines ”) were created to address this legal lacuna by examining the various ways in which DDE has been treated in international criminal law. The Guidelines identify overarching standards of treatment, derived from the jurisprudence of international criminal courts and tribunals (“ICCTs”), that practitioners should consider when collecting and tendering DDE.
