Article V. Amendment Process, Annenberg ClassroomBy Annenberg Classroom
Realizing that over time the nation may want to make changes to the Constitution, Article V establishes the amendment process. But unlike laws and regulations, which can be passed or amended by a simple majority of those voting in Congress, the Constitution is difficult to change. An amendment can be offered in one of two ways: when two-thirds of the Senate (67 of 100 senators) and two-thirds of the House of Representatives (290 of 435 representatives) call for a change to be made; or when two-thirds of the states (34 of 50 states) call for a national constitutional convention (a gathering of representatives of each state) to make a change.
Once the amendment is proposed, three-fourths of the state legislatures or state conventions (38 of 50 states) must vote to approve (ratify) the change. An amendment becomes effective when the necessary states have ratified it.
The article also forbids three specific amendments: that would deny a state its votes in the Senate, that before 1808 would enable Congress to prohibit the importation of slaves and that before 1808 would allow direct taxation except as based on the system of enumeration set out in Article I, Section 2. As a result, the three-fifths compromise contained in Article I, Section 9 remained in place until 1808 when Congress banned the international slave trade.Annenberg Classroom
