A High Court judge has described as "appalling" the presence of fabricated case authorities in proceedings and has written to regulators about the matter, the Law Society Gazette has reported. The referral, made directly by the judge rather than raised solely within a ruling, escalates the long-running concern over AI-generated and bogus legal citations into formal regulatory channels.

The judge's word carries weight. "Appalling" is the judge's characterisation of fake authorities that have surfaced at her level of the court. By writing to the bodies that oversee professional conduct, she has moved the issue beyond the individual case and into the disciplinary mainstream.

Why does it matter?

Legal citations are the connective tissue of argument. A listed authority that was never decided, or a neutral citation that points nowhere, distorts reasoning and can mislead opposing counsel, the judge, and the court itself. A fabricated citation is not a typo. It looks real, names judges, and gives a party a hook the brief cannot honour.

A High Court judge flagging the problem to regulators sends two signals at once. First, the judge considers the matter serious enough to escalate beyond the individual case. Second, fabricated authorities have reached the senior courts - not only tribunals and county courts where the phenomenon has been most discussed since generative AI tools became widely available in late 2022 and through 2023.

What does the referral change?

In most prior public incidents, bogus citations have produced wasted-costs orders in the case at hand and admonition in the judgment. The Gazette's report suggests this judge has gone further: notifying regulators so they can examine the conduct of those who put the fabricated authorities before the court.

That is a step the bench takes rarely. When a judge writes to a regulator, the matter leaves the case file and enters a disciplinary file, with consequences the practitioner cannot simply argue away in submissions.

What should practitioners do now?

• Verify every primary authority before tendering it. A neutral citation, a judge named in the catchwords, and a BAILII record are the minimum checks.
• Use BAILII, the National Archives' judgment search, or Westlaw / Lexis to confirm the case exists and supports the proposition.
• Where a citation cannot be verified, do not include it. Ask the author of the skeleton to confirm or replace it.
• Record the verification on the case file. If a regulator later asks, that note will assist in defending the conduct.
• Where an AI drafting tool produced the citation, treat that fact as a red flag, not an excuse.

Practitioners who cannot verify a citation should say so to the court rather than hope no one checks. Courts have, in the past 18 months, struck out skeletons and refused to hear argument based on unverified authorities.

Which regulators could act?

On the available reporting, neither the Solicitors Regulation Authority nor the Bar Standards Board has confirmed which body received the judge's letter. Both treat the deliberate tendering of false authorities as a disciplinary matter under their respective codes of conduct. Either can open an investigation on receipt of a judicial referral, and both publish anonymised warning notices when a complaint resolves without a finding.

Outcome ranges from a warning notice, through a fine, to strike-off where a pattern is established. A High Court judicial referral is likely to push the matter further along that spectrum than a single unverified citation would otherwise reach.

What remains unknown

The Gazette's headline report does not, on the face of the available text, identify the judge by name, the court division, the case reference, the parties, or the regulator addressed. The originating case in which the fake authorities appeared is also not stated in the headline.

For practitioners this uncertainty carries its own instruction. Until the full reporting is read, assume the court will scrutinise every citation in every skeleton argument and pleading, however minor, and ensure the file shows the work done to check each one.
