U.S. law refers to the legal system in the United States, which is based on the Constitution, statutes, regulations, and case law. The Constitution is the supreme law of the land, establishing the framework for government and protecting individual rights. Laws are created by legislative bodies, such as Congress at the federal level and state legislatures at the state level. The U.S. legal system is divided into two main categories: criminal law and civil law. Criminal law deals with offenses against the state, while civil law addresses disputes between individuals or organizations. Courts interpret and apply these laws, ensuring justice and order in society.
