Mavundla v. MEC
High Court · Jan 8, 2025
What happened in this matter?
The court dismissed the application for leave to appeal with costs, ordered the legal representatives to pay costs de bonis propriis, and referred the conduct of the legal practitioners to the Legal Practice Council for investigation due to the submission of fabricated case law.
- Why the court cared
- Justice Bezuidenhout issued a lengthy and stern warning on the professional obligation to verify authorities. She held that “relying on AI technologies when doing legal research is irresponsible and downright unprofessional,” and emphasized that even ignorance of AI’s flaws does not excuse unethical conduct. The judgment discusses comparative standards, ethical obligations, and recent literature in detail
- Why it matters now
- Never delegate citation verification to juniors without review — supervising counsel pays de bonis propriis when fakes slip through.

AI Use
The judgment does not explicitly confirm that generative AI was used, but the judge strongly suspects ChatGPT or a similar tool was the source. The judge even ran prompts into ChatGPT and confirmed that the tool responded with fabricated support for the same fake cases used in the submission. Counsel blamed overwork and delegation to a candidate attorney (Ms. Farouk), who denied AI use but gave vague and evasive answers.

Aon SA, Makro Properties v. Raal, Standard Bank v. Lethole — none found in SAFLII or major reportersCitations were often invented or misattributed to irrelevant decisions (e.g., a Competition Tribunal merger approval cited as support for service rules)The supplementary notice of appeal included misleading summaries with no accurate paragraph citations, and no proper authority was ever provided for key procedural points.
