The work "Introduction to Criminal Procedure," fully updated up to Law 5134/2024, is a user-friendly and example-rich manual of Criminal Procedure, whose presentation of the material largely coincides with the structure of the articles of the Code of Criminal Procedure (Law 4620/2019). The relevant concepts are explained succinctly without unnecessary formulations, and the texts of the law—often quoted verbatim—are accompanied by the necessary interpretative comments. It is a comprehensive aid from every perspective for the student, the legal professional, and anyone generally involved with the application of criminal law.
