United States Law
The Constitution is the supreme law of the land. It is supplemented by the treaties entered into by the US government, both domestic and foreign. Congress enacts law pursuant to the Constitution. These laws are codified in the US Code (USC). Federal agencies charged with carrying out these laws operate under rules. Federal agency rules are codified in the Code of Federal Regulations (CFR). The federal courts interpret and apply the constitution, statutes and regulations in the cases before them. Their decision in these cases make up the common law. Court rules govern these proceedings. The Resources below provide access to each of these pieces of the federal law.
