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 bill proposes a constitutional amendment to limit the Supreme Court to no more than 9 justices. It would directly affect the composition of the Supreme Court by preventing future expansions beyond the current 9-justice structure. The key provision requires a constitutional amendment, which would need ratification by 38 state legislatures (three-fourths of states) within seven years of congressional submission. Congress would also gain authority to pass laws enforcing this limit. The amendment does not change the current court size but aims to restrict future changes to the Court's membership.
