Unratified amendments.
Unratified amendments.
Collectively, members of the House and Senate typically propose around 150 amendments during each two-year term of Congress. Most however, never get out of the Congressional committees in which they were proposed, and only a fraction of those that do receive enough support to win Congressional approval to actually go through the constitutional ratification process.
Six amendments approved by Congress and proposed to the states for consideration have not been ratified by the required number of states to become part of the Constitution. Four of these are technically still pending, as Congress did not set a time limit for their ratification. The other two are no longer pending, as both had a time limit attached and in both cases the time period set for their ratification expired.
