Federal Supplement

The Federal Supplement is a case law reporter published by West Publishing in the United States that includes select opinions of the United States district courts, and is part of the National Reporter System. Though West is a private company that does not have a legal monopoly over the court opinions it publishes, it has so dominated the industry in the U.S. that legal professionals uniformly cite the Federal Supplement for included decisions. The Federal Reporter series publishes opinions of the United States courts of appeals and the United States Court of Federal Claims; prior series had varying scopes that covered opinions of other federal courts as well. The United States Reports are the official law reports of the rulings, orders, case tables, and other proceedings of the Supreme Court of the United States.

The Federal Supplement organizes court opinions within each volume by the date of the decision, and includes the full official text of the court's opinion. West editors add headnotes that summarize key principles of law in the cases, and Key Numbers that classify the decisions by topic within the West American Digest System.

Although opinions designated by the courts as "for publication" or "publish" are included in the Federal Supplement, West editors also select certain opinions without such a designation for publication, as part of West's editorial process. Opinions explicitly designated "not for publication" will not be selected.

Unlike the "published" opinions of the United States Courts of Appeals—which are included in the Federal Reporter series and have full precedential value, binding the lower courts in the relevant judicial circuit and, to a lesser degree, the issuing Court of Appeals—published district court opinions do not constitute binding precedent. They may, however, be viewed as more persuasive than unpublished opinions.
