How October 2026 compares with recent months
Counts are decisions by decision date in the same snapshot. Recent months are still being filled in as decisions are added to the database, so a month's count can rise after we publish it; we have not measured by how much.
| Decision month | Decisions in the corpus |
|---|---|
| April 2026 | 129 |
| May 2026 | 155 |
| June 2026 | 136 |
| July 2026 | 136 |
| August 2026 | 121 |
| September 2026 | 101 |
| October 2026 | 31 (partial, through October 15, 2026) |
What we left out, and why
- Dollar totals. Only 3 of the 31 decisions carry an amount, in mixed currencies, so we do not add them up.
- Lawyer versus litigant. The tracker tags 25 decisions as self-represented. We did not classify the other 6 one by one, so we make no claim about lawyers beyond that.
- Which AI tool. 30 of 31 decisions have no identified tool, so a tool breakdown would mostly be "unknown".
- A country count for the month. The tracker's home page reports all-time coverage (see the table at the top), and the raw country labels in the dataset do not map one to one to that figure, so we do not recompute it.
Where the data comes from
The tracker imports, normalizes and classifies the AI Hallucination Cases Database by Damien Charlotin (© 2026 Damien Charlotin, CC BY 4.0), which identifies court and tribunal decisions where a party relied on hallucinated content. AI Vortex adds search, review and analysis, and no endorsement by Charlotin is implied. The database covers decisions that address the issue, not every fake citation filed. See the full tracker, its case list and the downloadable dataset.
For background, see our longer pages on the AI sanctions tracker, hallucination case statistics and how the public trackers differ. If you file with AI-assisted research, the citation verification guide and the pre-filing checklist cover the steps courts keep citing in these orders.

Operational information, not legal advice.
