1,600 fake citations later.
Courts have now documented well over a thousand matters in which AI-invented authorities reached a filing, with sanctions climbing into six figures. The pattern is boringly consistent — and the fix is a verification habit any student can copy from the profession that learned it the hard way.
the scale of it.
The most complete count comes from a tracker maintained by researcher Damien Charlotin, which passed 1,600 documented matters worldwide by mid-2026. An April 2026 analysis of the same data put U.S. and international proceedings at 1,313, of which 496 involved licensed attorneys rather than self-represented litigants. Sanctions have escalated in step: from four-figure orders in 2023 to a combined penalty exceeding $110,000 in Couvrette v. Wisnovsky, where briefs contained 15 nonexistent cases and 8 fabricated quotations.
three cases that show the pattern.
| case | what happened | consequence |
|---|---|---|
| Couvrette v. Wisnovsky (Oregon) | Briefs with 15 cases that do not exist and 8 quotations no court ever wrote. | Orders across late 2025 and early 2026 totaling over $110,000 — the largest known U.S. penalty so far. |
| Lacey v. State Farm (C.D. Cal.) | Roughly 9 of 27 citations in one supplemental brief were wrong; at least two authorities were invented. Two major firms involved. | About $31,000 in fees imposed jointly on the firms. |
| Gonzalez v. Texas Taxpayers and Research Association (W.D. Tex.) | Counsel first denied using AI, then admitted an AI citation tool produced nonexistent and misleading citations. | Filing struck; nearly $4,000 in fees and costs — plus the credibility damage of the initial denial. |
Different courts, firms, and tools; identical anatomy. Generated text arrived with authorities attached, the authorities were never opened, and the first person to actually look them up was the opposing party or the judge.
why models invent citations.
Bar guidance on hallucination makes the mechanism plain: a language model produces the most plausible continuation of text, and a plausible-looking citation is easy to produce without any underlying case, article, or page existing. The format is learned; the referent is optional. That is why fabricated citations look more polished than real ones — the model optimizes for the shape of authority, not its existence.
It follows that no amount of prompt-craft makes generated citations trustworthy by default. Verification is not a nice-to-have layered on top of the workflow; it is the workflow.
the same failure, in student writing.
Swap the brief for a term paper and the anatomy is unchanged: a generated bibliography full of plausible authors, real-sounding journals, and DOIs that resolve to nothing. Instructors increasingly spot-check references for exactly this reason, and a fabricated source in a works-cited list is an academic-integrity conversation, not a formatting error.
The professional cases are useful to students precisely because the stakes were high enough to be documented: they show that the failure survives intelligence, credentials, and deadline pressure, and is prevented only by opening the sources.
a verification routine that works.
- 01Open every source you citeNot the first page of search results for its title — the source itself. If you cannot retrieve it, you cannot cite it.
- 02Verify the quotation against the pageFabricated quotations inside real sources are the subtler failure. Check the words and the page number you attribute them to.
- 03Build references from the source's own detailsConstruct the entry from the document in front of you — authors, year, title, publisher, DOI — rather than accepting a generated reference wholesale. A citation builder helps with format; the details must come from the source.
- 04Keep retrieval evidence for anything fragileFor webpages and other unstable sources, keep the access date and a saved copy, so the citation can be defended after the page changes.
Formatting is the easy half, and it is the half worth automating — a citation generator that produces APA 7, MLA 9, or Chicago 17 entries you then check against the real source keeps the labor where it belongs: on existence, not punctuation.
