Judgments and tribunal decisions of the UK courts, from The National Archives’ Find Case Law service: the Supreme Court, Privy Council, Court of Appeal, High Court, Court of Protection, Family Court, the Upper and First-tier Tribunals and the Employment Appeal Tribunal.

Search by subject, party or judge, then read the full text of any judgment from its neutral citation — so a quoted passage or a cited authority can be checked against what the court actually wrote.

This is UK law only. US case law is a separate corpus served by court-listener (search_case_law, find_case, get_opinion); an American authority returned for a UK question is a wrong answer, not a near miss.

The usual path is search_uk_caselaw → take the neutral_citation or identifier → get_uk_judgment.

Neutral citations

A neutral citation maps onto a Find Case Law path by rule — [2026] EWHC 1996 (Comm) is ewhc/comm/2026/1996, [2023] UKSC 42 is uksc/2023/42. The rule is a good first guess, so get_uk_judgment tries it and falls back to searching the citation text when the derived path 404s, reporting which route resolved it in resolved_by. Either form is accepted as input.

Caveats worth passing to a user

• Coverage starts recently. Find Case Law holds judgments the courts published to it — comprehensively from 2003 for some courts and much later for others. A missing older authority means not held here, not no such case. For historic authority a law-report subscription is still the answer.
• An unrecognised court code is rejected, not ignored. search_uk_caselaw returns unknown_court_code and points at list_uk_courts. Codes look like uksc, ewca/civ, ewhc/comm and cannot be guessed from a court’s name.
• Search is over the judgment text, so a phrase the court would actually write finds more than a legal concept it never names.
• Judgments are long — 140k–450k characters is ordinary. get_uk_judgment bounds the response with max_chars and sets truncated so a cut-off text is never mistaken for the whole judgment.
• Only newest, oldest and relevance sort. Upstream answers an unrecognised sort with an empty feed, which would read as “no such cases”, so the pack rejects one instead of passing it through.
