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.
Constitution of Finland
In 1991, the direct popular election of the President was introduced, with provision for a second ballot where necessary. The new system was used for the first time in 1994. The President's term of office was also limited to two consecutive terms of six years, and the President’s powers were limited in that he or she could henceforth only dissolve Parliament on receipt of a reasoned request from the Prime Minister and having first consulted the Speaker and the party groups in Parliament. The 1991 reform also amended the provisions in the Constitution Act and the Parliament Act relating to State finances.
