The Supreme Court of the United States handed down seven per curiam opinions during its 2018 term, which began October 1, 2018, and concluded October 6, 2019.
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: Clarence Thomas, Ruth Bader Ginsburg, Stephen Breyer, Samuel Alito, Sonia Sotomayor, Elena Kagan, Neil Gorsuch, Brett Kavanaugh (confirmed Oct. 6, 2018)
