Appointments to the Supreme Court are nominated by the President and approved by the United States Senate. There is a hearing, and one more than half of the Senate must approve in the affirmative for the appointment to be valid.

The Senate
In a presidential form of government, the legislative branch typically approves the appointments of members of the judicial branch. For example, in the United States, the President nominates judges, including Supreme Court justices, but these nominations must be confirmed by the Senate. This system of checks and balances ensures that no single branch has unchecked power over judicial appointments.
Presidential nominations of federal court judges are made with the "advice and consent" of the Senate, just as Supreme Court nominations are. The Senate must confirm the nomination by a simple majority of those voting in order for the judge to be commissioned.
