Bill > HJRes1

This joint resolution proposes a constitutional amendment that would permanently establish the Supreme Court of the United States as having nine justices: one chief justice and eight associate justices. The proposed amendment would require ratification by the legislatures of three-fourths of the states (currently 38 states) within seven years of its submission. This is significant because while nine justices has been the standard for many decades, it is not currently mandated by the Constitution, which means Congress could theoretically change the number of justices. By proposing this amendment, the resolution seeks to constitutionally lock in the current court structure and prevent potential future attempts to expand or reduce the number of justices, a process sometimes referred to as "court packing." The resolution was introduced with the support of two-thirds of both the Senate and House of Representatives, which is the threshold required for proposing a constitutional amendment.
