With the discussion on the new Dutch Code of Criminal Procedure and the introduction of new (technological) investigative methods (such as hacking), the question arises whether the protection of the suspect’s privacy in Dutch criminal procedure – which is somewhere between minimalistic and non-existent at the moment – needs to be revised. To this end, a comparison with German Constitutional Law and Criminal Procedural Law will be made. The focus will be on the German concept of ‘Kernbereich privater Lebensgestaltung’, which can be translated as the protection of the core aspect of a private life.
