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.
Twentieth Amendment to the United States Constitution
Section 2 moves the yearly start date of congressional sessions from the first Monday in December, as mandated by Article I, Section 4, Clause 2, to noon on January 3 of the same year. This change eliminated the extended lame duck congressional sessions. As a result of this change, if the Electoral College vote has not resulted in the election of either a president or vice president, the incoming Congress, as opposed to the outgoing one, would have to do so, following the process articulated in the Twelfth Amendment.
