UNC Law's AI justices match a Supreme Court ruling, not its feel

Three ChatGPT-based AI justices reached the same result as the US Supreme Court in an October 22 mock argument at the University of North Carolina School of Law, voting 2-1 in Monsalvo Velázquez v. Bondi, a 2025 immigration case. The panel, built by data librarian Rolando Rodriguez from one ChatGPT model, used textualist, pragmatist and progressive approaches; the pragmatist and progressive backed extending a 60-day voluntary-departure deadline that fell on Saturday to Monday, while the textualist dissented. The court ruled 5-4, with Justice Neil Gorsuch writing the majority and Justices Clarence Thomas and Samuel Alito dissenting. Nicole Downing, UNC Law’s assistant dean for AI, said the exercise tested AI’s capacity to reason as a judge does, not to replace judges.
