The respondent was denied workers' compensation benefits by the Workplace Safety and Insurance Appeals Tribunal, which found no causal link between his 1979 workplace back injury and his current back problems.
The Divisional Court allowed the respondent's application for judicial review, finding the Tribunal's decision patently unreasonable.
The Tribunal appealed.
Applying the newly established Dunsmuir standard of reasonableness, the Court of Appeal allowed the appeal and reinstated the Tribunal's decision, holding that the Divisional Court erred by reweighing the evidence and that the Tribunal's factual findings were supported by the record and entitled to deference.
