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).
President of Colombia
Already the Constitution of 1991 limited presidents to a single term. However, on 24 November 2005, the Colombian Congress introduced the Electoral Guarantees Law (Ley de Garantias Electorales), which modified Article 152, of the Colombian Constitution of 1991 and allowed a president to run for a second term. The President or Vice President running for re-election must officially tell in the National Electoral Council and guarantee a fair competition for the other contenders. Participation of acting officials in political proselytism was standardized. If the president or vice president are not running for office, they are prohibited from participating on political proselytism. If one or both are participating, they can engage in political activity only four months before the primary elections. Also, if the president and/or vice president is running for office, he may participate in their political party's selection mechanism to postulate candidates. In 2010, the Constitutional Court of Colombia threw out a planned referendum to allow presidents to run for three consecutive terms. It ruled that Colombian presidents can only serve two terms, even if they are nonconsecutive. In 2015, a constitutional amendment repealed the 2004 changes and reverted to the original one-term limit.
