US Supreme Court Chief Justice John Robe

US Supreme Court Chief Justice John Roberts is followed by Elena Kagan on her way to take the Judicial Oath to become the 112th US Supreme Court justice, and only the 4th woman to take the job, at the West Conference room of the Supreme Court in Washington on August 7, 2010. Senators voted 63-37 on August 5 to confirm Kagan as one of the nine justices who act as final arbiters of the US Constitution, set precedent for lower courts, and decide the nation's toughest moral and legal dilemmas.
