A joint resolution proposing an amendment to the Constitution of the United States to require that the Supreme Court of the United States be composed of nine justices.

This bill proposes a constitutional amendment to require the U.S. Supreme Court to have exactly nine justices. Currently, Congress sets the Court's size through legislation, but this amendment would make the nine-justice structure a permanent requirement in the Constitution. It would need ratification by three-fourths of state legislatures within seven years to become part of the Constitution. If adopted, it would prevent Congress from changing the Court's size via ordinary legislation.
