Amicus curiae (“friend-of-the-court”) briefs are briefs written by individuals or groups who are not directly involved in a legal case but have expertise or insight to offer a court to assist in making its decision. Since 1962, APA has filed nearly 250 amici briefs based on the most up-to-date and rigorously tested psychological science and research. As of 2025, 26 of APA's amicus briefs were cited directly by the U.S. Supreme Court and another 23 were cited directly in the decisions of lower courts.
APA's Amicus Curiae Brief Program is supported by the Amicus Curiae Expert Panel, a group of eight psychologists with expertise in various psycho-legal areas. Members of the panel assist the Office of General Counsel (OGC) by drafting and reviewing briefs, identifying additional relevant expert psychologists, and engaging in regular scanning of the environment for cases where psychological science could be utilized for the benefit society and to improve human lives.
