An introductory chapter examines the rationale for a crime of conspiracy and identifies the problems encountered in interpreting or applying the doctrine of conspiracy. Subsequent chapters address the elements of conspiracy, multiple-object conspiracies and accompanying issues, issues affecting parties, the heads of conspiracy at common law and limiting the heads of conspiracy at common law, statutory crimes of conspiracy, conspiracy for a crime, conspiracy to defraud, conspiracy to pervert the course of justice, miscellaneous statutory conspiracies, proving a conspiracy, the indictment of criminal conspiracy, procedural issues, and reform of conspiracy. Currently, the common law offense of conspiracy consists in an agreement between two or more individuals for the effectuation of one or more acts whose nature is such that at common law each of them renders an agreement for its effectuation criminal. The problem arises in the identification of the range of unlawful acts, objects, or purposes that render an agreement for their effectuation an indictable conspiracy at common law. 995 footnotes
