Federal law refers to the body of law created by the federal government of a country. In the United States, it encompasses statutes, regulations, and treaties that are enacted by Congress and signed by the President. Federal law is supreme over state laws, meaning that if there is a conflict, federal law prevails. This legal framework governs a wide range of issues, including immigration, taxation, and civil rights. Federal laws are enforced by various agencies, such as the Federal Bureau of Investigation (FBI) and the Environmental Protection Agency (EPA), ensuring compliance and addressing violations.
