The nomination and confirmation of justices to the Supreme Court of the United States involves several steps, the framework for which is set forth in the United States Constitution. Specifically, Article II, Section 2, Clause 2, provides that the president of the United States nominates a justice and that the United States Senate provides advice and consent before the person is formally appointed to the Court. It also empowers a president to temporarily, under certain circumstances, fill a Supreme Court vacancy by means of a recess appointment. The Constitution does not set any qualifications for service as a justice, thus the president may nominate any individual to serve on the Court.
In modern practice, Supreme Court nominations are first referred to the Senate Judiciary Committee before being considered by the full Senate. Since the late 1960s, the committee's examination of a Supreme Court nominee almost always has consisted of three parts: a pre-hearing investigation, followed by public hearings in which both the nominee and other witnesses make statements and answer questions, and concluding with a committee decision on what recommendation to make to the full Senate (favorable, unfavorable or no recommendation). Once that recommendation is reported to the Senate, floor debate can begin ahead of a confirmation vote. A simple majority vote is needed for confirmation.
