Derivative criminal liability includes inchoate offenses (criminal attempt, conspiracy, preparatory offenses, etc.), complicity (joint perpetration, perpetration through another, incitement, solicitation, accessoryship, etc.), organized crime, natural and probable consequences liability, post-crime aid, enterprise liability, terrorism and terrorist infrastructure, and many more forms of criminal liability, clearly making it a major pillar of modern criminal law. Although derivative criminal liability affects countries worldwide, there is still no general legal theory that covers this issue. The objective of the present book is to develop a comprehensive, general, legally sophisticated, and at the same time practical theory of derivative criminal liability.
