UK Case Law — Find Case Law

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.

Part of Pipeworx — an MCP gateway connecting AI agents to 1866+ live data sources. This is an independent, unofficial integration — not affiliated with, endorsed by, or published by the upstream provider.

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.

This is not all UK law

Find Case Law is a real but partial corpus. A 0-row result means not found here, never no such case:

• No Crown Court, County Court or Magistrates' Court judgments. Most of what those courts decide is given orally and never transcribed, so Find Case Law structurally cannot hold it.
• No dockets, pleadings or filings. This is judgments only — there is no UK equivalent of PACER here.
• Scotland and Northern Ireland's own court systems are not covered. Only England & Wales courts and the UK-wide apex courts/tribunals (Supreme Court, Privy Council, Employment Appeal Tribunal, Upper Tribunal) are indexed. A case that also went through the Court of Session or a Scottish/NI appeal may still appear here only for its UK-level leg.
• The Employment Appeal Tribunal only — not the first-tier Employment Tribunal. eat covers appeals; ET claims before they reach appeal are a different, uncovered corpus (see the uk-tribunals pack/task).
• No citator/treatment data. A judgment comes back as published, with no signal on whether it was later overturned, doubted or followed.
• Coverage is mostly 2001 onward, comprehensively from 2003 for some courts and much later for others (see Caveats below).

Tools

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.

Licence note. The Open Justice Licence covers per-query pass-through — a caller searches, we relay the matching judgments back — but it explicitly excludes "computational analysis": bulk programmatic extraction or mirroring/indexing the corpus requires a separate licence Pipeworx does not hold. This pack is not, and must not become, a mirror of Find Case Law.
