Automatic summary, not yet reviewed
- The law protects witnesses and experts in criminal cases when the judge finds a serious danger to them or their closest relatives.
- The investigating judge can hide the witness's or expert's name, home, workplace and profession, and can even have them appear without their face being visible.
- They are protected from being photographed and, in exceptional cases, they can be given a new identity, money to move, and police protection.
- The trial court can keep, change or remove the protection measures, and protected statements only count as evidence if they are confirmed at the oral trial.
