When Are Conclusions of Law Made in a Summary Judgment Motion Binding on the Trial Judge?

As summary judgment motions become the more common way for parties to resolve their disputes, Ontario Courts have had to deal with the consequences of a failed motion. A recent decision of the Ontario Court of Appeal, Skunk v. Ketash, 2016 ONCA 841, answers the question of whether a judge who dismisses a motion for summary judgment has in fact made conclusive rulings of law that will later bind the trial judge.

Skunk involved a motor vehicle accident. The plaintiff was a passenger in a car owned by his wife, but driven by his friend. In addition to bringing an action against his friend, the plaintiff sued his insurer pursuant to the uninsured provisions of the policy. He argued that since his friend was driving his wife's vehicle at the time of the accident without his wife's consent and his friend did not have insurance, he was entitled to coverage under his uninsured automobile policy. The insurer brought a motion for summary judgment to dismiss the husband's claim.
