If you, as a direct stakeholder, do not agree with the prosecutor’s decision not to prosecute the defendant, you can file a complaint with the court. This is referred to as an Article 12 Sv procedure and refers to the relevant article of the Code of Criminal Procedure. The court will decide whether the defendant should still go to court following your complaint.
For PSG, this means that we are regularly asked questions by the lawyer who assists a victim of a crime. After gaining access to the court documents (Art. 51 Sv), lawyers often come across extensive research files. These files often also contain reports of findings on digital forensics, requiring specialist knowledge to assess whether further scrutiny makes sense. It is not uncommon for the investigation to conclude that nothing relevant has been found, unclear where it is sought and at least as important, where no search has been made.
What seems irrelevant at some point in the investigation may prove to be of great importance at a later date!
