The Solicitor General is appointed by the President of the United States to assist the Attorney General and supervises and conducts government litigation in the United States Supreme Court. Virtually all such litigation is channeled through the Office of the Solicitor General and is actively conducted by the Office. The United States is involved in about two-thirds of all the cases the U.S. Supreme Court decides on the merits each year.
The Solicitor General determines the cases in which Supreme Court review will be sought by the government and the positions the government will take before the Court. The Office's staff attorneys participate in preparing the petitions, briefs, and other papers filed by the government in its Supreme Court litigation. The Solicitor General personally assigns the oral argument of government cases in the Supreme Court. Those cases not argued by the Solicitor General personally are assigned either to an attorney in the Office or to another government attorney. The Solicitor General also reviews lower court cases for possibility of appeal or participation as an amicus curiae.
