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).
Yoweri Museveni
President Yoweri Museveni, as the incumbent president of Uganda, signed the Constitutional Amendment Bill No. 2 2017, commonly known as the "Age Limit" bill on December 27, 2017. The bill was successfully passed by the 10th parliament of Uganda on December 20, 2017. As of December 27, 2017, in accordance with articles 259 and 262 of the Constitution of Uganda, the bill has effectively amended the Constitution to remove the presidential age limit caps. Before the amendment, article 102 (b) barred people above 75 and those below 35 years from running for the highest office. The current age limit bill also extends the term of office of parliament from the current five years to seven years. The bill also restores presidential two-term limits which had been removed in a 2005 constitutional amendment.
