swissblawg summarizes the ruling 1B_26/2016 of the BGer i.S. Ritzmann/Mörgeli:
- The Federal Supreme Court confirms a ban on the use of evidence from email and telephone data collected en masse by the University of Zurich, because there was no sufficient suspicion of a crime and the collection of data was unreasonable.
- These requirements had to be observed because the data collection was carried out on the initiative of the public prosecutor’s office, even if the university carried out the evidence collection without coercion, and because it interfered with the fundamental rights of the data subjects.
