Most of the states (36 of 49) require legislatures to approve the amendments during one legislative session. An additional four states require amendments to be passed during one or two successive legislative sessions, depending on whether the amendment receives a simple majority or supermajority.
Under Article V of the Constitution, there are two ways to propose and ratify amendments to the Constitution. To propose amendments, two-thirds of both houses of Congress can vote to propose an amendment, or two-thirds of the state legislatures can ask Congress to call a national convention to propose amendments.
A constitutional amendment can be initiated by the Legislature if it passes both houses by a two-thirds vote. A constitutional amendment does not need the Governor's signature, but becomes part of the constitution only if the electorate approves it at the next general election.
The amendment process is very difficult and time consuming: A proposed amendment must be passed by two-thirds of both houses of Congress, then ratified by the legislatures of three-fourths of the states.
Constitutional Amendments Proposal by convention of the states, with ratification by state conventions. Proposal by convention of the states, with ratification by state legislatures. Proposal by Congress, with ratification by state conventions. Proposal by Congress, with ratification by the state legislatures.
An amendment may be proposed by a two-thirds vote of both Houses of Congress, or, if two-thirds of the States request one, by a convention called for that purpose. The amendment must then be ratified by three-fourths of the State legislatures, or three-fourths of conventions called in each State for ratification.
The Constitution provides that an amendment may be proposed either by the Congress with a two-thirds majority vote in both the House of Representatives and the Senate or by a constitutional convention called for by two-thirds of the State legislatures.
Most of the states (36 of 49) require legislatures to approve the amendments during one legislative session. An additional four states require amendments to be passed during one or two successive legislative sessions, depending on whether the amendment receives a simple majority or supermajority.
Amendments and revisions A constitutional amendment may be placed on the ballot by either a two-thirds vote in the California State Legislature or by signatures equal to 8% of the votes cast in the last gubernatorial election through the exercise of the initiative power by the voters.
That is because an amendment by voter initiative is allowed, but a revision is not. A revision can only be made through a constitutional convention or by a ballot measure placed by the Legislature. A convention also requires action by the Legislature. This is pursuant to Article 18 of the California Constitution.
