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 an amendment to the United States Constitution that would mandate the Supreme Court consist of exactly nine members. Specifically, it would require the Court to be composed of one Chief Justice and eight Associate Justices. Currently, the Constitution does not specify the number of justices; instead, Congress has the power to change the size of the Court through regular legislation, which has happened several times throughout American history.

If this amendment were ratified, it would remove the ability of future Congresses to increase or decrease the number of seats on the Supreme Court without passing another constitutional amendment. For everyday citizens, this would mean the structure of the nation's highest court would be permanently set, preventing a practice often referred to as court-packing. Because this is a joint resolution proposing a constitutional amendment, it would require a two-thirds vote in both the House and Senate and ratification by three-fourths of the states to become law.
