The deceased's ex-wife and his common-law partner both claimed entitlement to his surviving spousal pension benefit.
The OMERS Appeal Sub-committee found in favour of the common-law partner.
The ex-wife successfully applied for judicial review, with the Divisional Court quashing the decision on the basis that the Tribunal failed to provide adequate reasons.
On appeal, the Court of Appeal held that the standard of review for the legal obligation to give reasons is correctness, not reasonableness.
Applying a functional approach, the Court found the Tribunal's reasons were sufficient as they explained why the decision was made and permitted effective judicial review.
The appeal was allowed and the application for judicial review dismissed.
