The new release is the complement to Volume I of General Criminal Law, which was already published in its 3rd edition by Roxin, focusing on the criminological foundations and the structure of crime theory. With Volume II, the presentation of the General Part of Criminal Law is now completed. Systematically convincing, scientifically fundamental, and linguistically brilliant, Roxin addresses the different forms of offenses in the second volume of his General Part. This includes authorship and participation, attempt, and omissions. Additionally, the relevant criteria for multiple offenses and their competition are presented. Roxin not only discusses these matters based on the prevailing opinion but also presents the most important arguments for and against a particular solution, allowing the reader to engage with the material.
