Criminal law is a technical and fairly broad field. Mastering it requires a long-term commitment. This book comes at just the right time as a comprehensive overview to help readers better grasp the subject. It presents the essentials of this field in a brief and concise manner. It combines in-depth doctrinal and case law analyses and is structured into two main sections. The first section introduces the basic concepts and fundamental principles of the subject. The second part is presented in the form of eleven essay topics. It explores criminal legality and the application of criminal law over time, the structure of a criminal offense, its three-part classification and its material elements, as well as attempted offenses and impossible offenses. The analysis also examines the dynamics of the actors involved, including punishable complicity and the distinction between complicity and coercion, without neglecting the factors contributing to crime. Finally, the book addresses the limits of criminal prosecution by examining grounds for criminal non-liability, self-defense, and the role of the criminal judge, all within the context of Togolese law.
