Background and facts

Le Rong Zhu, the appellant, was involved in a motor vehicle accident and subsequently made claims for statutory accident benefits under his insurance policy with Co-operators General Insurance Company. The claims included requests for benefits to cover assessments and treatments for both physical and psychological injuries that Zhu attributed to the accident. The insurer denied some of these claims, leading to a series of proceedings before the Licence Appeal Tribunal (LAT).

In January 2023, a LAT adjudicator issued a decision (the Initial Benefits Decision) that addressed Zhu’s entitlement to benefits for his alleged physical and chronic pain impairments. The adjudicator found, based on the medical evidence, that Zhu’s physical injuries from the accident had resolved within 6 to 12 weeks and that any ongoing pain was attributable to pre-existing conditions rather than the accident. As a result, the adjudicator denied Zhu’s claims for further treatment and assessments for those impairments. However, the adjudicator did find that Zhu’s psychological impairments were causally related to the accident and allowed benefits for a catastrophic impairment assessment relating to psychological injuries.

Zhu did not seek reconsideration or appeal of the Initial Benefits Decision. Later, he sought additional benefits for a catastrophic impairment assessment relating to his physical and chronic pain impairments. The insurer opposed this, arguing that the earlier decision barred further claims on the same issue.

Reconsideration and appeal

The matter returned to the LAT, where Adjudicator Pahuta reconsidered the prior decision. The adjudicator applied the doctrine of issue estoppel, concluding that the previous finding—that Zhu’s physical and chronic pain impairments were not caused by the accident—was final and binding. As a result, Zhu was precluded from claiming further benefits for a catastrophic impairment assessment related to those injuries. The adjudicator did, however, authorize benefits for a catastrophic impairment assessment related to psychological injuries.

Zhu appealed the reconsideration decision to the Ontario Superior Court of Justice (Divisional Court), arguing that the doctrine of issue estoppel was misapplied and that the prior decision did not make a final finding on causation for his physical and chronic pain impairments. The Court reviewed the relevant portions of the LAT’s decisions, including the medical evidence and the adjudicator’s reasoning.

Outcome and costs

The Divisional Court dismissed Zhu’s appeal, finding that the LAT had correctly applied issue estoppel and that the prior decision clearly determined the causation issue regarding Zhu’s physical and chronic pain impairments. The Court held that Zhu was estopped from re-litigating this issue and upheld the denial of further benefits for those impairments. The Court ordered Zhu to pay the insurer’s costs of the appeal, fixed at $5,000 all inclusive, in favor of Co-operators General Insurance Company. No damages or additional benefits were awarded to the appellant as a result of the appeal.
