The Supreme Court of the United States handed down eighteen per curiam opinions during its 2015 term, which began October 5, 2015 and concluded October 2, 2016.
Because per curiam decisions are issued from the Court as an institution, these opinions all 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: Antonin Scalia (died February 13, 2016), Anthony Kennedy, Clarence Thomas, Ruth Bader Ginsburg, Stephen Breyer, Samuel Alito, Sonia Sotomayor, Elena Kagan
