The prosecutor investigates crimes together with the police. He or she shall have contact with the person suspected of the crime, the victim and witnesses, and have close contact with the police.
Once the preliminary investigations have been completed, the prosecutor judges whether there is sufficient evidence to bring the case to court. If it is a minor crime, and the suspect admits his or her guilt, the prosecutor imposes a fine. This is referred to as an order of summary punishment, and no trial will be held.
If an action is initiated there will be a trial in a court of law. The task of the prosecutor is to prove that the suspect has committed the crime. He or she questions the suspect, the witnesses and experts in order to establish that the suspect is guilty.
