Which category of criminal procedures establishes the acts necessary to commit a crime?

Substantive law is the category of criminal procedures that defines what constitutes a crime and establishes the specific acts necessary to commit that crime. It focuses on the elements that must be proven for a specific crime to be established, such as intent, act, and causation. This legal framework outlines what is considered criminal behavior and sets the penalties for those offenses.

In contrast, procedural law deals with the rules that govern the process of legal proceedings, including how laws are enforced, rights during criminal trials, and the conduct of law enforcement. Constitutional law governs the principles and rules set forth in the constitution, including individual rights and liberties, but does not define crimes themselves. Federal law refers to the body of laws created by the federal government, which can include substantive laws, but it’s not specifically about the acts necessary to commit a crime. Thus, the correct response is substantive law as it directly addresses the elements that comprise criminal conduct.
