Iowa Case Law

Code & tools: github.com/docketx — legal-scrambler pseudonymises a case file on your own hardware before a frontier model sees it; claude-for-legal is the Claude Code plugin (docketx-open-law) that loads these datasets and checks citations against them.

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 83,272 Iowa appellate opinion documents from the public record, sliced from the Free Law Project / CourtListener bulk export of 2026-06-30.

Court coverage (2 court ids, explicit allowlist — never prefix-matched): iowa, iowactapp.

Lead opinions and separate opinions; documents under 1 characters excluded. Slice sha256 145838da38c4f47e08fd83dfab5a28cb899ecd745af0802d44c47999e0fbfa0a (also in slice.manifest.json).

Composition

Measured on this exact slice: 72,155 documents (86.6%) carry 2,000+ characters of text, 5,351 (6.4%) carry 200-1,999, and 5,766 (6.9%) 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.
