Fundamental law is the key to maintaining the rights and freedoms of every citizen in the United States of America. It is questionable how many people actually understand what is considered fundamental law, or why it is referred to as such. The US Constitution and the Bill of Rights -which was promised as part of the ratification of the US Constitution in order to ensure its passage-, are both considered to be the fundamental law of the United States. These documents, along with the Declaration of Independence are commonly referred to as our founding documents – the Charters of Freedom.
