LLMs fail to consistently base legal verdicts on cited authorities, study finds

By PulseAugur Editorial · [1 sources] ·

A new study published on arXiv has revealed that large language models, when used to justify legal decisions, often name the correct statutes or precedents but do not consistently base their verdicts on them. Researchers found that even when case facts were held constant and the cited legal authority was substituted, the models' verdicts changed inconsistently. This suggests that naming a legal authority is a weak indicator of a verdict's dependence on it, and the models remain vulnerable to adversarial manipulation. AI

IMPACT Highlights a critical limitation in LLM legal reasoning, suggesting current models may not be reliable for generating legally sound justifications.

    Cited but Not Consulted: A Counterfactual Audit of Legal Chain-of-Thought Faithfulness

    arXiv:2610.12361v1 Announce Type: new Abstract: Large language models increasingly justify legal decisions by naming the statute or precedent behind a verdict, treated as evidence that the decision follows from it. We test this directly: holding case facts fixed, we substitute th…
