There are currently three living retired justices of the Supreme Court of the United States: John Paul Stevens, Sandra Day O'Connor and David Souter. As retired justices, they no longer participate in the work of the Supreme Court, but may be designated for temporary assignments to sit on lower federal courts, usually the United States Courts of Appeals.
As of 2014, there are nine United States Supreme Court judges. The number of justices that sit on the Supreme Court is set by Congress and ranges from five to 10.
