The Implied Powers of Congress

Updated February 17, 2021 | Infoplease Staff

The inherent powers of the U.S. Congress

The expressed powers of Congress are listed in Article I of the U.S. Constitution (since they're listed out, they're also called the enumerated powers). Congress also has implied powers, which are based on the necessary and proper clause, or elastic clause. This is a provision in the Constitution which gives Congress right to make any laws needed to carry out their expressed powers. Congressional power has grown over several centuries, bolstered by Supreme Court decisions
