Re Walker

SC Victoria · Nov 24, 2025

Direct answer

What happened in this matter?

The Supreme Court of Victoria reprimanded a solicitor for filing submissions containing hallucinated case law generated by 'CourtAid' and 'ChatGPT'. The Court determined that the solicitor's failure to verify AI-generated output violated professional standards and the Court's specific AI guidelines, constituting unsatisfactory professional conduct.

Why the court cared
Misrepresented: Case Law | Two other authorities in the submissions were inaccurately cited or misnamed; the solicitor provided corrected names/copies for some but one corrected authority was irrelevant to the passing-over issue. || Fabricated: Case Law | Two authorities cited in the defendant's opening submissions could not be located; Supreme Court Library inquiries confirmed they did not exist and the solicitor said AI produced the references.
Why it matters now
Using legal-tech tools like CourtAid alongside ChatGPT does not excuse verification — reprimands follow regardless of tool pedigree.

Why this matter is tracked

In Re Walker [2025] VSC 714, the Supreme Court of Victoria addressed a solicitor's use of generative AI in preparing court submissions. The solicitor, Ms. Rizkallah, used 'CourtAid' and 'ChatGPT' to identify case law for a passing-over claim. These tools generated non-existent or hallucinated citations. The solicitor failed to verify the existence or relevance of these authorities before filing. The Court found this conduct constituted unsatisfactory professional conduct, as it violated the Court's May 2024 Guidelines on the responsible use of AI and fell below the standards of diligence expected of a competent practitioner. The Court exercised its inherent jurisdiction to impose a formal reprimand, noting the solicitor's genuine contrition and the fact that the hallucinated claims were not ultimately pressed at trial.

Operational lesson

Using legal-tech tools like CourtAid alongside ChatGPT does not excuse verification — reprimands follow regardless of tool pedigree.
