What happened

A 25-year-old lawyer in Ankara used AI to prepare a defense brief by generating citations to Court of Cassation (Yargıtay) decisions. During a hearing at Kızılcahamam District Civil Court on 18 June 2026, opposing counsel questioned the case numbers cited, prompting the judge to verify them in UYAP (the Turkish court case management system).

The judge found that the cited case numbers did not exist in UYAP. The lawyer stated that the AI had correctly identified real Court of Cassation decisions but invented or altered their case numbers and chamber designations. The court referred the matter the same day to both the Ankara Bar Association and the Chief Prosecutor's Office.

Reported impact

The lawyer reported being shocked during the hearing and stated this was his first experience with such a situation in a 25-year career. He was investigated but reported that prosecutors did not specify which crime he was being accused of.

Index analysis

The AI system generated realistic-looking court citations with correct decision content but fabricated or incorrect case reference numbers, presenting them as real precedents that could mislead courts and opposing parties about the sources cited.

Governance controls

The incident prompted discussions among lawyers about the risks of AI-generated legal documents and the need for stricter document verification in courts. Lawyer advocacy groups noted that no intent to deceive was evident and criticized the investigation as pressure on legal representation.
