This joint resolution proposes a significant amendment to the United States Constitution. The core purpose of this proposed amendment is to explicitly mandate that the Supreme Court of the United States shall always be composed of nine justices . For this amendment to become part of the Constitution, it must be approved by a two-thirds vote in both the Senate and the House of Representatives, and subsequently ratified by the legislatures of three-fourths of the several states within seven years of its submission. This measure aims to permanently fix the size of the nation's highest court, thereby preventing any future attempts to alter its composition through ordinary legislative processes.
