The StPO, or Strafprozessordnung, is the German Code of Criminal Procedure. It outlines the legal framework for criminal proceedings in Germany, detailing the rights and responsibilities of all parties involved, including the accused, victims, and law enforcement. The StPO aims to ensure fair trials and protect individual rights while maintaining public order. The StPO covers various aspects of criminal law, such as the investigation process, the roles of judges and prosecutors, and the procedures for appeals. It is essential for maintaining the rule of law and ensuring that justice is served in a transparent and efficient manner.
