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).
Mahinda Rajapaksa
On the 9th September 2010 the Parliament passed the amendment to remove presidential term limits from the Constitution. This amendment allowed Rajapaksa to run for a third term and cement his grip on power. The move came just a day after the Supreme Court ruled that a referendum was not required to make the change. The amendment had even more even more far-reaching consequences than just term limits, including provisions that increased the president's power to act without oversight removing an independent advisory council that the president currently must consult before appointing people to important nonpartisan posts, like Supreme Court judges and members of the human rights and electoral commissions. A Parliamentary Council without veto power and with only two opposition members was created in its place.
