Twenty-second Amendment to the United States Constitution
The amendment prohibits any individual who has been elected president twice from being elected again. Under the amendment, an individual who fills an unexpired presidential term lasting greater than two years is also prohibited from winning election as president more than once. Scholars debate whether the amendment prohibits affected individuals from succeeding to the presidency under any circumstances or whether it only applies to presidential elections.
Term limits in the United States
Term limits, also referred to as "rotation in office", restrict the number of terms of office an officeholder may hold. For example, according to the 22nd Amendment, the President of the United States can serve two four-year terms and serve no more than 10 years.
