The Code de procédure pénale is a legal framework in France that outlines the procedures for criminal investigations and trials. It establishes the rights and responsibilities of all parties involved, including the police, prosecutors, and defendants. This code ensures that legal processes are conducted fairly and transparently, protecting the rights of individuals while maintaining public order. This code is part of the broader French legal system and works alongside other legal texts, such as the Code pénal, which defines criminal offenses and penalties. Together, these codes help maintain justice and uphold the rule of law in France.
