Federal Supplement

The Federal Supplement (ISSN 1047-7306) is a case law reporter published by West Publishing in the United States that includes select opinions of the United States district courts since 1932, and is part of the National Reporter System.

Although the Federal Supplement is an unofficial reporter and 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 Supplement, including its supplementary material, is also available on CD-ROM compilations, and on West's online legal database, Westlaw.

Though West has copyright over its original headnotes and keynotes, the opinions themselves are public domain and accordingly may be found in other sources, chiefly Lexis, Westlaw's competitor.

Lexis also copies the star paginated Federal Supplement numbering in their text of the opinions to allow for proper citation, a practice that was the subject of an unsuccessful copyright lawsuit by West against the parent company of Lexis.
