Can Legal AI Platforms Predict U.S. Supreme Court Decisions? A Pre-Decision Test in Chatrie v. United States
Three legal AI platforms predicted the U.S. Supreme Court would reverse a Fourth Circuit decision in Chatrie v. United States, differing only on two justices' votes.Summary
The article describes an experiment where three legal AI platforms (CoCounsel, Harvey, and LexisNexis Protégé) were given case materials from Chatrie v. United States, a pending Fourth Amendment case involving geofence warrants. All platforms predicted the Supreme Court would reverse the Fourth Circuit's decision affirming the denial of Chatrie's suppression motion, with two predicting a 5-4 vote and one a 7-2 vote. The platforms differed on how Justices Kavanaugh and Barrett would vote. The study aimed to assess AI's ability to predict Supreme Court decisions, acknowledging limitations such as being a single-case test and potential external influences. The results suggest AI tools may offer strategic insights into appellate questions, though further study is needed.
