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.
2007 amendment to the Constitution of Kazakhstan
In addition to these proposals the Kazakh parliament passed an additional amendment two days later, lifting the term-limit clause on the first President of Kazakhstan, Nursultan Nazarbayev. The constitution limits a president to two five-year terms, but this amendment allows the incumbent president--Nazarbayev--to run for an unlimited number of five year terms. Some critics argued this move paved the way for him to become "de facto" President for life.
