Northbound Processing v. South African Diamond Regulator
High Court · Jun 30, 2025
What happened in this matter?
The court referred the applicant's legal practitioners to the Legal Practice Council for investigation after they admitted to including non-existent case law in their written heads of argument. The counsel attributed these errors to the use of an AI tool, 'Legal Genius,' which they failed to verify before filing.
- Why the court cared
- The court reasoned that legal practitioners have a trite duty not to mislead the court, regardless of intent. It held that written heads of argument are a critical memorial of counsel's position and that negligent reliance on AI-generated research that introduces fictitious cases undermines the administration of justice, necessitating a referral to the professional regulator.
- Why it matters now
- Even 'legal-specific' AI tools trigger Legal Practice Council referral; negligent reliance equals professional misconduct.
Why this matter is tracked
Fabricated: Case Law | Non-existent case cited to support interim mandamus propositions; court confirmed it does not exist and counsel later admitted AI hallucination. Outcome: Referral to the Legal Practice Council for investigation. "[92] In Mavundla, the court emphasised the trite duty of legal practitioners not to mislead the court, whether through negligence or intent. This includes the duty to present an honest account of the law, which means (inter alia) not presenting fictitious or non-existent cases.24 In my view, it matters not that such cases were not presented orally, but were contained in written heads of argument. Written heads are as important a memorial of counsel’s argument as oral argument and, for purely practical reasons, are often more heavily relied upon by judges.[...][95] In this case, counsel’s explanations bear out their submission that there was no deliberate attempt to mislead the court in relation to the use of incorrect case citations in the heads of argument. Their apologies are acknowledged. As is clear from Mavundla, however, even negligence in this context may have grave repercussions particularly to the administration of justice and, in appropriate circumstances, could constitute serious professional misconduct.[96] As a consequence, it is appropriate to make the same order as in Mavundla, namely that the conduct of theapplicant’s legal practitioners is referred to the Legal Practice Council for investigation."
Even 'legal-specific' AI tools trigger Legal Practice Council referral; negligent reliance equals professional misconduct.
