Congress makes which type of law? common law

Congress primarily makes **statutory law**. Statutory laws are written laws passed by legislative bodies, such as Congress in the United States. These laws are distinct from common law, which is developed through court decisions and precedents, and constitutional law, which pertains to the interpretation of the Constitution. Military law governs the armed forces, and while Congress has the power to enact laws related to military affairs, the term "military law" itself refers to the legal system governing members of the military.
