Legal Retrieval for Public Defenders, Stammbach et al., 2026, forthcoming in TMLR arxiv.org/abs/2601.14348 Here, we describe the research challenges we encountered while building the Resource Library. We also release a realistic benchmark for public defense retrieval (5/8)
- A team partnered with the New Jersey Office of the Public Defender to build NJ BriefBank, a tool that surfaces relevant appellate briefs.
- The paper reports that existing retrieval benchmarks fail to transfer to real public defense research.
- Adding domain knowledge such as query expansion with legal reasoning, domain-specific data, and curated synthetic examples improved retrieval quality.
