The Strafprozessordnung (StPO) is the German Code of Criminal Procedure that outlines the legal framework for criminal trials in Germany. It regulates the processes involved in investigating and prosecuting crimes, ensuring that the rights of both the accused and the victims are protected throughout the judicial process. The StPO covers various aspects, including the roles of law enforcement, the judiciary, and legal representatives. It also details procedures for gathering evidence, conducting hearings, and appealing decisions, thereby promoting fairness and transparency in the criminal justice system.
