On May 7, 1992, the State of Michigan ratified a 203-year-old proposed amendment to the United States Constitution, thereby fulfilling the terms of amending the document, adding it as 27th Amendment.
The amendment had been written by James Madison. He had presented it as part of the original twelve amendments that became the ten making up the Bill of Rights.
It bars the U.S. Congress from giving itself a pay raise until after the next election, so that voters have a chance to decide whether those voting for the raise would remain in Congress to receive it.
