LongJud-Bench - Evidence Marshalling (Second Instance): leaderboard
LongJud-Bench (LegalWorld, Zuo et al., 2026) makes a model the target lawyer in a simulated Chinese civil case, from client consultation to second-instance trial, with every other role played by Qwen3.5-Plus on a 100-case split. Evidence marshalling is scored on the new evidence in the second-instance appeal or response brief the agent drafts, by a Claude Sonnet 4.6 judge on a 0-10 rubric, normalized to percent; higher is better.
