"The task of the Office of the Solicitor General is to supervise and conduct 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 approximately two-thirds of all the cases the U.S. Supreme Court decides on the merits each year."

"If the petition in your case is so plainly meritless that the Court will not need the assistance of a brief in opposition, you may wish to waive your response. The solicitor general and state attorneys general often do this."
