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).
2015 Republic of the Congo constitutional referendum
The draft constitution was divided into 246 articles. It would allow a person to be elected as President three times, eliminate an age limit of 70 years for candidates, and reduce the length of presidential terms from seven years to five years. While eliminating the maximum age limit, it would reduce the minimum age requirement for candidates from 40 to 30 years. It would also establish the post of Prime Minister as head of government, rather than the President. The changes would allow President Denis Sassou Nguesso, whose second term was due to expire in 2016, to run for re-election.
