Thanks very much for linking that. This makes me think that legal support is actually one of the worst possible uses of LLM-based AI (at least as implemented here), primarily because so much of the source material is directly contradictory, e.g. a legislature passes a law which is subsequently overturned by the courts, or decisions in lower courts are reversed by higher courts, or higher courts reverse themselves over time. It feels like you'd absolutely have to annotate all the source material in some way to say whether it was still controlling law/precedent.
