THE HOUSE AND THE CONGRESS
The 10th amendment.
Of what country or state? The United States Constitution does not have that many amendments.
the 14th Amendment, which "nationalized" due process by applying it to the States as well as to the federal government.
In constitutional amendments, the single subject style of proposing amendment is mostly applied. Where several subjects are massed together in one legislative measure the ratifying state legislatures are prone to applying the item veto to signify their preferences in any such constitution amendment proposal. And where an item veto is applied to any matter in that proposal by a ratifying state legislature, the entire measure fails.
The United States Constitution may have an amendment added through two different avenues. The first avenue, the better known avenue, is to introduce the proposed amendment to the houses of Congress where it needs to pass a vote with a two-thirds majority vote. The second avenue to add an amendment is through a special Constitutional Convention that is called for by two-thirds of the State legislatures.
