Twenty-second Amendment to the United States Constitution
Some argue that the 22nd Amendment and 12th Amendment bar any two-term president from later serving as vice president as well as from succeeding to the presidency from any point in the presidential line of succession. Others contend that the original intent of the 12th Amendment concerns qualification for "service" (age, residence, and citizenship), while the 22nd Amendment, concerns qualifications for "election", and thus (strictly applying the text) a former two-term president is still eligible to "serve" as vice president (neither amendment restricts the number of times an individual can be elected to the vice presidency), and then succeed to the presidency to serve out the balance of the term (though prohibited from running for election to an additional term).
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.
