Where do I find Michigan Criminal Law Annotated?

In the United States, the law is derived from four sources. These four sources are constitutional law, administrative law, statutes, and the common law (which includes case law). The most important source of law is the United States Constitution. All other law falls under, and is subordinate to, that document. No law may contradict the United States Constitution. For example, if Congress passes a statute that conflicts with the constitution, the Supreme Court may find that law unconstitutional, and strike it down.
