This is a non-sale item, a hard-to-find training material, Criminal Procedure Law I (Investigation), published by the Legal Training and Research Institute (located in Kasumigaseki, Tokyo). It is new and unused. This is a constitutional law textbook used by Ministry of Justice staff, including prosecutors (prosecution clerks), immigration control officers, prison officers, probation officers, and Ministry of Justice bureau staff, for elementary training, etc. This material is supervised by instructors (active prosecutors who are guaranteed to become executives such as chief prosecutors in the future) working at the Legal Training and Research Institute under the jurisdiction of the Ministry of Justice, and explains the investigation of criminal procedure law. Prosecutors have the authority to arrest and detain suspects, and to indict or not indict them. This is the I (Investigation) of the training materials that explain criminal procedure law, divided into three sections: investigation, evidence, and trial. The depth of the content differs from criminal procedure law textbooks written by scholars, covering topics such as police officers' questioning, inspection of belongings, inquest, suspect examination, undercover investigation, ordinary arrest, emergency arrest, arrest in flagrante delicto, referral to family court, and appeals against non-prosecution. It explains in an easy-to-understand manner the interesting content of how the prosecution secures the suspect's custody, how it collects evidence, and in what cases it indicts (summary prosecution/public trial) or does not indict. This is the perfect material for the general public, university students, and those preparing for the bar exam (the bar exam is hosted by the Ministry of Justice). The quality is different from textbooks from commercially available bar exam preparatory schools. There is a limited number of copies, so please purchase as soon as possible. I am also listing many other items. Thank you (click on the seller's photo of S-chan at the bottom).
