Zou v. Miracon Development: BC Supreme Court Flags AI Hallucinations in Self-Represented Litigants Costs Submissions (Jan 2026)

Case at a Glance

Background

Jinlu Zou and Huan Yi Zhou, appearing as self-represented plaintiffs, brought a dispute against Miracon Development Inc. regarding a property transaction. On 12 December 2025, they obtained judgment for $4,800. The defendant requested the opportunity to make submissions on costs. Both parties submitted written arguments on costs in December 2025. In their costs submissions, the plaintiffs cited legal authorities that Justice Blok found to be AI-hallucinated — non-existent cases that appeared to support their costs arguments.

The AI Issue

The BC Supreme Court had to deal with costs submissions that contained AI-generated fabricated case citations. Justice Blok addressed the hallucinated authorities in the published costs judgment — flagging them as non-existent and declining to rely on them. The case is significant as one of the first Canadian provincial superior court decisions to explicitly address AI hallucinations in costs proceedings, a context where self-represented litigants often seek to rely on precedents they are not equipped to verify.

• The BC Supreme Court found that the plaintiffs’ costs submissions cited cases that did not exist — AI hallucinations identified in a published costs judgment [Canadian superior court hallucination case].
• Justice Blok declined to rely on the fabricated authorities in determining the costs order [no legal effect given to hallucinations].
• The decision is one of Canada’s first provincial superior court judgments to explicitly address AI citation hallucinations [Canadian precedent].
• The self-represented plaintiffs had won on the merits but undermined their costs position with fabricated authority [pyrrhic victory on costs].
• The case confirms that costs proceedings — often handled informally — are within the AI citation risk zone [procedural risk].

“The Court notes that some authorities cited in the plaintiffs’ costs submissions appear to be the product of AI hallucination — cases that do not exist and cannot be verified in any legal database.”

— Justice Blok, BC Supreme Court, Zou v. Miracon Development Inc., 20 January 2026

The India Angle

Indian Law Equivalent: Costs proceedings in India under Order XX CPC and the High Court rules involve submissions on the appropriate costs order after a case is decided. Self-represented parties who win on the merits frequently seek cost awards. The Zou case illustrates that AI-generated citations in costs submissions can undermine even a successful party’s position. Indian courts awarding costs under Section 35 CPC would apply the same analysis.

Bar Council Rules: The BCI Rules apply to advocates, not self-represented parties. However, as more Indian litigants use AI tools, courts will need to develop protocols similar to those emerging in Canada and Australia. For advocates handling costs proceedings, verifying all cited precedents — including costs-specific decisions from the High Court and Supreme Court — is mandatory.

Practical Advice for Indian Advocates: Costs are often an afterthought in Indian litigation, but the Zou case shows that AI errors in costs submissions can affect the final costs order. Verify all cited precedents for costs arguments on SCC Online and Manupatra. Even minor proceedings deserve the same verification standard as the main case.

Quick Takeaways

• Even winning litigants can undermine their position with AI-hallucinated citations — verification duty applies equally to costs submissions.
• Canadian provincial courts are now producing AI hallucination jurisprudence — the Commonwealth legal world is aligned on this issue.
• Indian advocates handling costs arguments must verify all cited precedents, including costs-specific orders and rulings on the scale of costs.
