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).

The approved constitutional reforms included a limitation on the presidency to at most two four-year terms, judicial supervision of elections, a requirement for the president to appoint at least one vice president, a commission to draft a new constitution following the parliamentary election, and easier access to presidential elections by candidates—via 30,000 signatures from at least 15 provinces, 30 members of a chamber of the legislature, or nomination by a party holding at least one seat in the legislature.
