How to Amend the Constitution?

One way to amend the constitution, although it has never been used. A bill to pass both houses of the legislature, by two-thirds majority in each. Once the bill has passed both houses, it goes to states. This is the route taken by all current amendments. Because of some long outstanding amendments, such as the 27th, Congress will normally put a time limit for the bill to be approved as an amendment. You can find more information here:
