U.S. Federal Law refers to the body of laws created by the national government of the United States. It includes statutes passed by the U.S. Congress, regulations issued by federal agencies, and decisions made by the Supreme Court. Federal law applies to all states and can override state laws when there is a conflict. Federal laws cover a wide range of issues, including civil rights, immigration, and taxation. They are designed to ensure consistency and protect the rights of individuals across the country. Citizens can challenge federal laws in court, and the judicial system interprets these laws to ensure they align with the U.S. Constitution.
