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).
Colombian Constitution of 1991
The President is directly elected to a four-year term in a two-round election. The 1991 Constitution originally limited the President to a single, non-renewable lifetime term, but a controversial 2004 constitutional amendment supported by then-President Álvaro Uribe permitted a President to serve two terms. This provision allowed President Uribe and his successor, Juan Manuel Santos, to successfully seek second terms in 2006 and 2014 respectively. In 2015, a constitutional amendment repealed the 2004 changes and reverted to the original one-term limit.
