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 not more than 9 justices.

This joint resolution proposes an amendment to the U.S. Constitution that would permanently limit the size of the Supreme Court to a maximum of nine justices. Currently, the Constitution does not specify the number of justices, leaving that decision to Congress, which has changed the size of the Court several times throughout American history. If passed and ratified, this measure would prevent future Congresses from increasing or decreasing the number of seats on the Court without passing another constitutional amendment.
