Roc Nation Accuses Opposing Counsel of Using…

In July 2026, the entertainment agency Roc Nation requested that a federal judge in New York strike segments of a legal brief filed by Terrance Dixon, alleging that the document relies on fabricated quotations generated by artificial intelligence. The dispute arises from an ongoing sanctions battle related to a broader lawsuit filed by Dixon against rapper Joseph Antonio Cartagena, professionally known as Fat Joe.

What happened

Roc Nation, which manages Cartagena, submitted a letter to the court alleging that Dixon’s legal brief contains numerous citations that exhibit the hallmarks of AI hallucination. According to the agency, while the underlying court cases cited by Dixon are genuine, the specific language attributed to them does not exist in the original rulings. Roc Nation identified at least 17 instances where quotations included in the brief cannot be found within the source material, noting that Dixon built legal arguments around these fabricated excerpts.

In addition to the citation issues, Roc Nation flagged procedural violations, including that the brief was submitted past a court-ordered deadline without an extension request and exceeded the court-mandated word limit. Dixon’s attorney, Tyrone Blackburn, denied the allegations of AI-generated hallucinations. Blackburn insisted that the cited cases are authentic and attributed the discrepancies to his decision to paraphrase rulings rather than provide verbatim quotations. He further accused Roc Nation’s legal team of misrepresenting a U.S. Supreme Court holding in their own filings. Amidst this dispute, Blackburn disclosed his intention to withdraw as counsel, citing a conflict of interest related to a separate defamation lawsuit involving one of Cartagena’s attorneys. The presiding judge has yet to rule on the motion to strike the disputed portions of the brief.
