Why this matter warrants attention
The STF dismissed the complaint as manifestly inadmissible, sanctioned the claimant for bad faith litigation by ordering payment of double the initial court costs, and referred the counsel to the OAB for investigation into potential violations of the Statute of Advocacy due to the submission of AI-generated filings containing fabricated legal authorities.
The Court reasoned that the petition was 'manifestly inadmissible' because the cited precedents were either non-existent or misrepresented. The Relator noted that the 'Criado com MobiOffice' watermark, combined with the presence of fabricated citations and false summaries of Súmula Vinculante 6, evidenced that the counsel used AI to draft the petition without any subsequent human review, constituting reckless conduct and bad faith under Article 80, V, of the Brazilian Civil Procedure Code.
MobiOffice and similar built-in AI assistants require the same verification discipline as ChatGPT—courts treat watermarks as admission.
