When the Supreme Court rules on a constitutional issue, that judgment is virtually final; its decisions can be altered only by the rarely used procedure of constitutional amendment or by a new ruling of the Court. However, when the Court interprets a statute, new legislative action can be taken.

The Supreme Court Database is the definitive source for researchers, students, journalists, and citizens interested in the U.S. Supreme Court. The Database contains over two hundred pieces of information about each case decided by the Court between the 1791 and 2022 terms.

The opinions of the Supreme Court of the United States are published officially in the United States Reports. See 28 U. S. C. §411.

Each opinion sets out the Court's judgment and its reasoning and may include the majority or principal opinion as well as any concurring or dissenting opinions. All opinions in a single case are published together and are prefaced by a syllabus prepared by the Reporter of Decisions that summarizes the Court's decision.
