Questions this page answers
- How many court decisions in the corpus involve pro se litigants and AI hallucinations?
- 1,267 of the 2,202 records (57.5%) list a pro se party, counted from the public corpus last checked 2026-10-22. The most recent record is dated 2026-10-15.
- Can a pro se litigant be sanctioned for AI-generated fake citations?
- Courts in the corpus have responded with warnings, struck filings, dismissals, costs orders and monetary sanctions. 539 pro se records include a warning, and 59 record a US dollar amount. The largest recorded US dollar amount is USD 66,129.
- Does this show that self-represented parties misuse AI more than lawyers?
- No. The corpus counts decisions where a court recorded hallucinated material. It does not measure how many filings were prepared with AI, and self-represented filings are not tracked on the same basis as lawyer filings. Treat the counts as recorded incidents, not usage-adjusted rates.
- Which countries have the most recorded pro se AI hallucination decisions?
- US (894), Canada (182), Australia (86), GB (45), Israel (13), New Zealand (7), and 40 more in other jurisdictions. Country is the jurisdiction recorded for each decision.
- Where does this data come from and how is it counted?
- The records come from Damien Charlotin's AI Hallucination Cases Database (CC BY 4.0), normalized by AI Vortex. Records whose "party" field contains "pro se" (case-insensitive), counted from the same public corpus file the case pages use. The page and its count are rebuilt from the corpus on each deployment.
Method and limits
Records whose "party" field contains "pro se" (case-insensitive), counted from the same public corpus file the case pages use. Source: Damien Charlotin, AI Hallucination Cases Database, CC BY 4.0. Amounts are counted only where a decision records US dollars; no totals are summed across currencies. A record establishes what a court recorded, not intent or how often AI is used by any group. Verify against the linked decision before relying on it.
