Yes, the Constitution can be changed through a formal amendment process described in Article Five of the United States Constitution. Amendments can be proposed either by a two-thirds vote in both houses of Congress or by a constitutional convention called for by two-thirds of state legislatures. To become part of the Constitution, a proposed amendment must then be ratified by three-fourths of the state legislatures or state conventions. This process is deliberately difficult to ensure stability but allows for necessary changes over time.
