Washington Case Law
Source & credit — Free Law Project / CourtListener
Every opinion in this dataset comes from the Free Law Project / CourtListener bulk export of 2026-06-30 (10,798,347 opinions). CourtListener gathered, cleaned, deduplicated and published that record; Free Law Project — the 501(c)(3) non-profit behind it, building free public access to American law since 2010 — pays for it. We sliced and reformatted; they did the hard part. Go to the source: https://www.courtlistener.com.
Free Law Project is a non-profit, and it is worth supporting: https://free.law/donate/. If this data is useful to you, credit Free Law Project and CourtListener too, and consider going straight to the source: CourtListener runs its own API and MCP server.
Full text of 150,239 Washington appellate opinion documents from the public record, sliced from the Free Law Project / CourtListener bulk export of 2026-06-30.

Composition
Measured on this exact slice: 91,345 documents (60.8%) carry 2,000+
characters of text, 45,663 (30.4%) carry 200-1,999, and 13,231
(8.8%) are under 200 characters. The short ones are real records, not errors: certiorari
denials, one-line orders, and judgment entries. They are kept deliberately (min_chars = 1)
so this is the complete public record rather than a filtered subset. Filter on len(text) if you want
only substantive opinions.
Format
Rows follow docketx record v1 (one opinion per line): id, doc_type, jurisdiction, title,
text, source, license, retrieved_at, plus citation, court, date, and extra
(CourtListener opinion/cluster ids, opinion type). The same format is used across every
docketx dataset.
Provenance and license
Judicial opinions are edicts of government: uncopyrightable works of the public domain (Banks v. Manchester, 128 U.S. 244 (1888); Georgia v. Public.Resource.Org, 590 U.S. 255 (2020)). This packaging is released under CC0 1.0. Source: CourtListener bulk export (2026-06-30), Free Law Project — https://free.law. This dataset redistributes public-domain court text; it adds no annotation and asserts no rights.
