Ninth Amendment to the United States Constitution

The Ninth Amendment (Amendment IX) to the United States Constitution addresses rights, retained by the people, that are not specifically enumerated in the Constitution. It is part of the Bill of Rights.

The amendment as proposed by Congress in 1789 reads as follows:

The enumeration in the Constitution, of certain rights, shall not be construed to deny or disparage others retained by the people.

When the U.S. Constitution was put to the states for ratification after being signed on September 17, 1787, the Anti-Federalists argued that a Bill of Rights should be added. One of the arguments the Federalists gave against the addition of a Bill of Rights, during the debates about ratification of the Constitution, was that a listing of rights could problematically enlarge the powers specified in Article One, Section 8 of the new Constitution by implication. For example, in Federalist , Alexander Hamilton asked, "Why declare that things shall not be done which there is no power to do?" Likewise, James Madison explained to Thomas Jefferson, "I conceive that in a certain degree ... the rights in question are reserved by the manner in which the federal powers are granted" by Article One, Section 8 of the Constitution.

The Anti-Federalists persisted in favor of a Bill of Rights during the ratification debates, but also were against ratification, and consequently several of the state ratification conventions gave their assent with accompanying resolutions proposing amendments to be added. In 1788, the Virginia Ratifying Convention attempted to solve the problem that Hamilton and the Federalists had identified by proposing a constitutional amendment specifying:

That those clauses which declare that Congress shall not exercise certain powers be not interpreted in any manner whatsoever to extend the powers of Congress. But that they may be construed either as making exceptions to the specified powers where this shall be the case, or otherwise as inserted merely for greater caution.
