Nature of Criminal Procedure Law

According to van Apeldoorn, the nature of criminal procedure law is as public law and accusatoir. Criminal Procedure Law as public law because it regulates public interests. According to van Apeldoorn, acts that can be subject to punishment are no longer seen merely as errors that directly affect the person who is harmed, but primarily as violations of legal order, as violations of society. Meanwhile, criminal procedure law is accusatoir because the positions of the plaintiff (public prosecutor) and the defendant are facing each other as parties with equal rights, who are engaged in a legal battle (rechsstrijd) before an impartial judge.
