Amicus Curiae
Amicusuh-MEE-kuss KYOO-ree-eye
Latin: 'friend of the court.' A non-party who files a brief offering perspective or expertise on a legal question before the court.
Plain-English definition
An amicus curiae brief is filed by someone who is not a party to the case but believes they have something useful to add to the court's consideration. Common in appellate courts and especially the U.S. Supreme Court, where amicus briefs from trade associations, advocacy groups, and academics regularly outnumber the briefs of the parties.
