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.
NLRB v. Noel Canning
In "Federalist No. 67," Alexander Hamilton wrote that the appointment power was ordinarily confined jointly to the President and the Senate, but considering it unlikely that the Senate would remain continuously in session, the Constitution allowed the President to make temporary appointments when the Senate is in recess. Since the advent of nearly year-round sessions, the United States Senate no longer has long recesses. That has potentially changed the meaning of the Recess Appointment Clause of the Constitution, which has affected the way the Senate and the President interact.
