U.S. Constitution

The Constitution is the founding document for the United States federal government. It is the basic and "supreme law of the land." It defines the structure of the federal government, provides the legal foundation on which all its actions must rest, and guarantees the rights due to its citizens. No laws may contradict any of the Constitution's principles. The federal courts have jurisdiction to interpret the Constitution and evaluate the constitutionality of federal and state laws.
