This joint resolution introduces a proposed amendment to the United States Constitution, fundamentally altering the requirements for admitting new states into the Union. The core change mandates that the concurrence of two-thirds of both the House and Senate is necessary for any new state to be admitted, moving beyond the current simple majority requirement. The proposed amendment also reiterates existing constitutional provisions regarding the formation of states, ensuring no new state can be created within another state's jurisdiction or by combining states without the consent of the concerned state legislatures and Congress. For this amendment to be adopted, it must be ratified by the legislatures of three-fourths of the several States within a seven-year period from its submission by Congress.
