Executive Summary: Key Legal and Evidentiary Issues

• The accident on January 14, 2020, caused by Eric Michael Sullivan, was deemed the sole responsibility of the defendant.

• The court had to consider whether the collision aggravated pre-existing injuries from two earlier accidents in 2015 and 2018.

• Evaluation focused on distinguishing new harm from already compensated conditions.

• Psychological deterioration was found to be significantly linked to the 2020 accident.

• The court rejected treating damages as “indivisible,” instead apportioning compensation for the incremental harm.

• ICBC retained the right to seek deductions under section 83 of the Insurance (Vehicle) Act within 14 days.

Facts and outcome of the case

Background of the case
The plaintiff, Leah Kathleen Tench, was involved in a motor vehicle collision on January 14, 2020, when her vehicle was rear-ended by the defendant, Eric Michael Sullivan. This accident was her third, following earlier crashes in 2015 and 2018. Prior to the subject accident, she already lived with chronic pain, traumatic bilateral thoracic outlet syndrome (TOS), and psychological stress resulting from her previous injuries.

Issues before the court
The central questions were whether the subject accident worsened her pre-existing physical and psychological conditions, how damages should be allocated given that she had previously received compensation for earlier injuries, and whether liability should rest entirely with the defendant.

Court’s findings
The court held that Sullivan was entirely at fault for the 2020 collision. Importantly, it found that the accident exacerbated Tench’s symptoms, particularly her psychological difficulties, adding a new and significant layer of suffering on top of her pre-existing conditions. While the defense argued that damages should be treated as indivisible across all her accidents, the court rejected this, emphasizing that compensation must reflect the incremental harm caused by the latest crash.

Damages awarded
The total award amounted to $282,071.64. This included $187,806.50 for loss of future earning capacity, $40,000 for non-pecuniary damages covering pain and suffering, $49,986 for future care costs, and $4,279.14 for special damages. The Insurance Corporation of British Columbia (ICBC) was given a 14-day period to apply for deductions under section 83 of the Insurance (Vehicle) Act. If no adjustments were sought, the full sum would be payable to the plaintiff, along with costs assessed at Scale B.

Outcome
The decision reinforced that defendants bear full liability when their actions cause additional harm, even where a plaintiff has existing vulnerabilities from prior accidents. It clarified that damages should not be merged into a single pool of prior injuries but instead carefully measured to account for the new harm inflicted by the most recent negligent act.
