EPIC Amicus Curiae Briefs

EPIC frequently files amicus curiae, or "friend of the court", briefs in federal and state appellate cases concerning emerging privacy and civil liberties issues.

We work closely with technical experts and legal scholars, members of the EPIC Advisory Board, on these briefs. EPIC's amicus briefs assist judges in their analyses of novel privacy issues, often involving new technology. Many of these cases are complex and technical. Judges often acknowledge EPIC's briefs in their opinions, and have expressed gratitude for EPIC's participation in important cases. EPIC's decision to participate as amicus in a particular case typically follows an extensive review of matters pending before federal and state courts.
