Twenty-second Amendment to the United States Constitution
The amendment prohibits any individual who has been elected president twice from being elected again. Under the amendment, an individual who fills an unexpired presidential term lasting greater than two years is also prohibited from winning election as president more than once. Scholars debate whether the amendment prohibits affected individuals from succeeding to the presidency under any circumstances or whether it only applies to presidential elections.
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.
