Article Five of the United States Constitution detailed the two-step process for amending the nation's frame of government. Amendments must be properly Proposed and Ratified before becoming operative. This process was designed to strike a balance between the excesses of constant change and inflexibility.
The Amendment process is the formal way to change the Constitution. An amendment may be proposed by two-thirds vote of both houses of Congress or by a convention called by Congress at the request of two-thirds of the state legislatures.
