What is the official reporter for the decisions of the United States Supreme Court?

The official reporter for the decisions of the United States Supreme Court is the United States Reports. This series is published by the Supreme Court of the United States and contains the final, authoritative version of the Court's opinions and decisions, along with relevant summaries, headnotes, and order lists. It has been in publication since 1754 and is essential for legal professionals who need to reference Supreme Court rulings for precedent and legal analysis.

The other options listed do not serve as the official reporter for Supreme Court decisions. For instance, the Supreme Court Reporter is a commercially published series that may provide similar content, but it is not the official source. The Federal Supplement is a reporter for decisions of the federal district courts and courts of appeals, not the Supreme Court. The Justice Reports is not an official reporter associated with U.S. Supreme Court decisions.
