Facts and outcome of the case

Background and parties involved

This case arose from the collapse of a shared wall between two properties in Vancouver, British Columbia. The plaintiff, Ming Sun Benevolent Society, owned a building adjacent to the premises previously owned and used by the Philippine Women Centre of B.C. (PWC). The collapse led to significant property damage, resulting in both parties losing the use of their respective buildings. The plaintiff brought a civil claim in negligence and nuisance against PWC and two additional defendants—Wan Yao Chow and Double Happiness Holdings (2007) Ltd.—alleging they were responsible for the collapse. The defendants counterclaimed, alleging the plaintiff’s own negligence caused the structural failure and sought damages in return.

Trial and legal arguments

The trial lasted 26 days. The plaintiff argued it was entitled to full damages and costs, despite a finding of contributory negligence. It further sought a single, holistic award of costs against all defendants, arguing the claims and counterclaims were factually and legally inseparable. The defendants contested liability and insisted that costs should be apportioned and assessed separately for each party and each legal claim.

Court's findings on liability and damages

The court found in favor of the plaintiff and awarded damages in the amount of $1,537,740.26, but reduced this by 15% due to contributory negligence on the part of Ming Sun. The counterclaim by the defendants was dismissed entirely. The court concluded that the central liability issue—what caused the wall collapse—was common to both the plaintiff’s claim and the defendants’ counterclaim. Therefore, the claims were too intertwined to be treated separately for cost allocation.

Costs determination and litigation conduct

Costs were awarded to the plaintiff on the basis that it was the successful party in both the claim and the counterclaim. The court ruled that the defendants were jointly and severally liable for 85% of the plaintiff’s costs related to the claim and 100% of the costs related to the counterclaim. Costs were assessed on Scale B, with a 1.5x uplift applied to trial-related steps under Appendix B, s. 2(5) of the Supreme Court Civil Rules, due to the defendants’ disruptive litigation conduct. This conduct included late disclosure of documents, amended pleadings on the eve of trial, and attempts to introduce evidence mid-trial without proper notice.

Offer to settle and double costs

The plaintiff had extended a formal offer to settle on July 17, 2024, offering to pay $160,000 to the defendants along with their legal costs. This offer was open until July 31, 2024, and was not accepted. Given the plaintiff's significantly better outcome at trial, the court awarded double costs from July 31, 2024, onward, as per Rule 9-1 of the Supreme Court Civil Rules.

Final disposition

In summary, the court awarded the plaintiff damages of $1,537,740.26, reduced by 15% for contributory negligence. The plaintiff received its full costs for defending the counterclaim and 85% of its costs for the claim, with a 1.5x uplift applied to trial costs and double costs awarded after the settlement offer date. The defendants were held jointly and severally liable for these amounts.
