Twenty-second Amendment to the United States Constitution
As worded, the primary focus of the 22nd Amendment is on limiting individuals twice elected to the presidency from being elected again. Due to this, several issues could be raised regarding the amendment's meaning and application, especially in relation to the 12th Amendment, ratified in 1804, which states, "But no person constitutionally ineligible to the office of President shall be eligible to that of Vice-President of the United States". While it is clear that under the 12th Amendment the original constitutional qualifications of age, citizenship, and residency apply to both the president and vice president, it is unclear whether someone who is ineligible to be elected president could be elected vice president. Because of this apparent ambiguity, there may be a loophole in the 22nd Amendment whereby a two-term former-president could be elected vice president and then succeed to the presidency as a result of the incumbent's death, resignation, or removal from office (or even succeed to the presidency from some other stated office in the presidential line of succession).
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.
