What the record shows
The Seventh Circuit found that the petitioner's opening brief contained roughly two dozen quotations that do not exist, seven cases incorrectly identified as circuit precedent, and assertions contradicted by the record, which counsel attributed to ChatGPT. The court imposed a $5,000 fine on attorney Abdullah Salah under Federal Rule of Appellate Procedure 46(c), declined to sanction the contracted drafting attorney (Farah Chalisa) at that time, and referred the matter to the Illinois Attorney Registration and Disciplinary Commission.

The test this filing did not run
Every matter in this record shares one mechanism: a citation that did not resolve to an opinion in the reporter named, in a brief that was filed before any verification step ran. Veritas runs that step. The Filing Risk Scanner extracts each citation, resolves it against reporter and public-record sources, and returns a verdict on each one — located, partial, or not located in reporter — before the brief is signed.
