The specific powers and duties of the U.S. Congress are enumerated in several places in the Constitution. The most important listing of
these powers is in Article I, Section 8, which identifies in 17 paragraphs the many important powers of Congress. The last paragraph grants to Congress the flexibility to create laws or otherwise to act where the Constitution does not give it the explicit authority to act. This clause is known as the Necessary and Proper Clause, although it is not a federal power, in itself.
The Necessary and Proper Clause allows Congress "To make all Laws which shall be necessary and proper for carrying into Execution the [enumerated] Powers, and all other Powers vested by this Constitution in the Government of the United States, or in any Department or Officer thereof." (Article I, Section 8, Clause 18). It is also sometimes called the "elastic clause." It grants Congress the powers that are implied in the Constitution, but that are not explicitly stated. That is why the powers derived from the Necessary and Proper Clause are referred to as implied powers.
The correct way to interpret the Necessary and Proper Clause was the subject of a debate between Secretary of the Treasury ALEXANDER HAMILTON and Secretary of State THOMAS JEFFERSON. Hamilton argued for an expansive interpretation of the clause. His view would have authorized Congress to exercise a broad range of implied powers. On the other hand, Jefferson was concerned about vesting too much power in any one branch of government. He argued that "necessary" was a restrictive adjective meaning essential. Jefferson's interpretation would have strengthened STATES' RIGHTS. GEORGE WASHINGTON and JAMES MADISON favored Hamilton's more flexible interpretation, and subsequent events helped to foster the growth of a strong central government. Their debate over the Necessary and Proper Clause between Hamilton and Jefferson came to a head in a landmark U.S. Supreme Court case, MCCULLOCH V. MARYLAND, 17 U.S. 316 (1819).
McCulloch v. Maryland was the first case in which the U.S. Supreme Court applied the Necessary and Proper Clause. Some constitutional historians believe that the opinion in McCulloch v. Maryland represents an important act in the ultimate creation of the U.S. federal government. The case involved the question of whether Congress had the power to charter a bank. At first, this question might seem inconsequential, but...
