In its ruling of 14 May 2019 (C-55/18), the European Court of Justice ruled that Member States must oblige employers to set up a system for measuring the daily working time of employees. How exactly this obligation has to be implemented in Germany has not yet been decided by the German legislator. In its decision in June 2020, the Berlin-Brandenburg Regional Labor Court clarified that at least a time recording system using fingerprints is – in principle - not permitted in Germany.
