CourtListener researched, assembled and maintains these judge records; [Free Law Project](https://free.law) — the 501(c)(3) non-profit behind it, building free public access to American law since 2010 — pays for it. We reformatted; they did the hard part.

Coverage is strongest for federal judges and state appellate judges; many state trial judges are not in this database, and for those the opinions themselves (see `docketx/us-caselaw`) name the presiding judge. ## Load it ```python from datasets import load_dataset judges = load_dataset("docketx/us-judges", "judges") positions = load_dataset("docketx/us-judges", "positions") ``` Part of the [DocketX](https://docketx.ai) open legal corpus, alongside `docketx/us-caselaw` (the national opinion corpus) and `docketx/oral-arguments-us` (argument transcripts).
