The federal government has the power to

The federal State is divided into three distinct, divided and separate branches: legislative, executive and judicial, whose powers are conferred by the United States Constitution in Congress, the president and federal courts, respectively. Each branch has an exclusive sphere of its own competence and powers that allow them to limit the actions of the other two branches. The purpose of this system is to avoid the tyranny that would occur if one branch of public power concentrated too much power and dominated the other two. The powers and duties of these branches are defined in greater detail by the minutes of the Congress, including the creation of executive departments and lower courts to the Supreme Court.

The laws of the United States are contained in the federal legislation, compiled in the Code of the United States; the rules dictated by the administrative agencies recognized by the legislation to promulgate them; and judicial and agency decisions interpreting statutes and regulations.
