The Supreme Court of the United States handed down nineteen per curiam opinions during its 2009 term, which began on October 5, 2009, and concluded October 3, 2010. Because per curiam decisions are issued from the Court as an institution, these opinions lack the attribution of authorship or joining votes to specific justices. All justices on the Court at the time the decision was handed down are assumed to have participated and concurred unless otherwise noted.
Chief Justice: John Roberts
Associate Justices: John Paul Stevens, Antonin Scalia, Anthony Kennedy, Clarence Thomas, Ruth Bader Ginsburg, Stephen Breyer, Samuel Alito, Sonia Sotomayor
