WCAT Decision A2501051 (Hilary Thomson)

BC Workers' Compensation Appeal Tribunal · Aug 18, 2025

Direct answer

What happened in this matter?

The tribunal dismissed the worker's appeal for lack of jurisdiction due to an untimely filing. It explicitly identified that the worker's submissions contained AI-generated hallucinations, including fabricated case law and misapplied policies, and warned that such conduct may result in cost awards or the tribunal disregarding the arguments entirely.

Why the court cared
The tribunal reasoned that the Workers Compensation Act provides no authority to extend the one-year filing deadline for prohibited action complaints. It further determined that the worker's reliance on AI-generated content resulted in submissions that were inaccurate and unhelpful, failing to meet the party's obligation to provide truthful information under the Code of Conduct.

Why this matter is tracked

In a prohibited action complaint appeal, the BC Workers' Compensation Appeal Tribunal (WCAT) dismissed the worker's appeal for lack of jurisdiction, as the complaint was filed beyond the one-year statutory limit. The tribunal identified that the worker's written submissions contained significant inaccuracies, including citations to repealed policies and non-existent or misrepresented case law. The tribunal concluded these submissions were likely generated by artificial intelligence. While the tribunal declined to award costs in this specific instance because the appeal was dismissed at an early stage, it cautioned that parties have an obligation to ensure the accuracy of their submissions and that reliance on AI for legal research may lead to cost awards or ignored arguments.

Tracked discrepancy record

4 citation, quotation, or authority issues are recorded in the source dataset.

  1. Outdated Advice: Repealed Law | Cited Policy D3-115-1 as recognizing late prohibited action complaints; tribunal found D3-115-1 is not a current Prevention Manual policy and does not support the asserted proposition.
  2. Fabricated: Case Law | Provided a 2019-format citation that, when searched in WCAT's current A- format, corresponded to an unrelated appeal (the cited case did not support the worker's point).
  3. Fabricated: Case Law | Included at least one case citation that appears not to exist and was likely fabricated by AI.
  4. Misrepresented: Case Law | Cited WCAT decisions purportedly supporting late filings; first cited decision had nothing to do with late filings or the topic for which it was cited.
