applying to the United States Congress under Article V of the United States Constitution to call for a convention proposing an amendment to the constitution fixing the number of justices of the United States Supreme Court at one chief justice and eight associate justices.

South Dakota's Senate Joint Resolution 502 is a state application to the U.S. Congress seeking to trigger a constitutional convention under Article V. It requests Congress call a convention specifically to propose an amendment fixing the U.S. Supreme Court's composition at one Chief Justice and eight Associate Justices. This resolution does not change the Court's current size (nine justices total) but formally asks Congress to begin the process for a constitutional amendment. The application is a procedural step intended to be part of a broader effort requiring support from two-thirds of state legislatures to proceed.
