The 27th Amendment regulates congressional pay increases by preventing any increase in pay from taking effect until after the next set of elections, allowing voters to retaliate against increases they view as unjust. It was originally proposed in 1789 as part of the Bill of Rights but was not ratified for over 200 years until 1992. Gregory Watson, a university student, researched the amendment and began a campaign that led to its ratification by 38 states, the final being Michigan.
