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 joint resolution proposes a constitutional amendment to permanently set the number of justices on the Supreme Court at nine. It would require the Supreme Court to always consist of exactly nine justices, directly affecting the Court's composition. The amendment would become part of the Constitution only if ratified by three-fourths of state legislatures within seven years. This is a procedural change to the Constitution's structure, not a policy affecting other areas.
