The progress of digitalization does not stop at the criminal procedure. This concerns the preliminary investigations, the main proceedings as well as the appellate proceedings and therefore all three stages of the trial. The use of digital tools in the main proceedings is of utmost interest since this phase is construed as the center of the criminal proceedings. In Austria, there are different forms and extents of digitalization, which concern either recordings of the proceedings or the use of live links within the proceedings. When one thinks about these cases, issues regarding fundamental principles of the criminal procedure arise. What can be considered progress must therefore also be viewed critically.
