Twenty-second Amendment to the United States Constitution
The Twenty-second Amendment (Amendment XXII) to the United States Constitution sets a limit on the number of times an individual is eligible for election to the office of President of the United States, and also sets additional eligibility conditions for presidents who succeed to the unexpired terms of their predecessors.
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.
