The functions of the ombud include investigating complaints related to the norms and standards on his or her own initiative or after being informed. The ombud may subpoena any person to appear before him or her and, where appropriate, can also refer the complaint to any other authority, body or entity established to deal with similar complaints. No self-incriminating answer or statement made to the ombud may be used against that person in criminal proceedings. After each investigation, the ombud submits a report together with recommendations on appropriate actions to the CEO.
