Definition of U.s. supreme court justices

<onlyinclude>This is a list of past and present Justices of the Supreme Court of the United States. Justices of the Supreme Court of the United States are nominated by the President of the United States and approved by the U.S. Senate, with at least half of that body voting in the affirmative. Generally, a justice's qualifications are made by the President and, most visibly, by a Senate hearing. There is no qualification of age or experience that is a standard to be met; instead, there is a much more subjective process taken by the Senate, occasionally resulting in a sometimes controversial defeat of judicial nominees.
