For over fifty years, UNDERSTANDING THE CONSTITUTION has provided an accessible introduction to the document that defines and limits the powers of the United States and the rights of individuals. Thorough and precise, this textbook walks through, clause by clause, the entire Constitution, including all original articles and all subsequent amendments, and explains what the document says, as well as the key Supreme Court cases that define that part of the law. Updated thoroughly every three years, it includes the most recent developments in constitutional law.
