Goh Chin Cheng v Choco Up SG Pte Ltd
High Court · May 4, 2026
What happened in this matter?
The High Court of Singapore sanctioned counsel for misciting authorities, including the use of a fictitious quotation. The court ordered counsel to personally pay 900 SGD in costs to the opposing party, emphasizing that the sanction must be borne by counsel and not passed to the client.
- Why the court cared
- The court applied the three-stage Ridehalgh test for professional negligence, finding counsel acted improperly and negligently by failing to verify authorities. The court determined that the miscitations were material to central issues, posed a high risk of misleading the court, and caused the opposing party to incur unnecessary costs. The court held that the sanction was necessary for fairness, integrity of the justice system, and deterrence.
- Why it matters now
- This case highlights the judiciary's focus on counsel's duty to verify research, regardless of whether AI was used. It establishes that misrepresenting existing authorities is treated with similar severity to citing fictitious ones, particularly when the miscitations are material to the case.

In Goh Chin Cheng v Choco Up SG Pte Ltd [2026] SGHCR 13, the Singapore High Court addressed counsel's miscitation of authorities in written submissions.

Applying the Ridehalgh test for professional negligence, the court found counsel's conduct improper and negligent. Consequently, the court ordered counsel to personally pay 900 SGD in costs to the opposing party, explicitly prohibiting the passing of these costs to the client.
