Supreme Court Nominations Fast Facts

(CNN)Here's a look at Supreme Court nominations.

Under Article II of the Constitution, the President nominates justices to the Supreme Court, with the "advice and consent of the Senate."
If a vacancy occurs when Congress is not in session, a recess appointment allows an appointee to serve without Senate approval until Congress reconvenes.
One hundred and sixty-two nominations have been submitted to the Senate (including nominations for chief justice). Of those, there have been 125 confirmations, with seven instances of individuals declining to serve.
