On appeal from summary judgment dismissing an intended class proceeding, the court held that the proposed claim for restitution of late payment penalties charged by a regulated gas utility was not an impermissible collateral attack on Ontario Energy Board rate orders, and that statutory and regulatory defences based on the Ontario Energy Board Act, the Criminal Code, and a regulated industries doctrine did not bar the proceeding.
The majority nevertheless dismissed the appeal on the merits, finding the unjust enrichment claim failed because receipt of the penalties did not constitute an enrichment in the utility's regulatory context and, in any event, the Board-ordered rate structure supplied a juristic reason for retention.
The court declined preservation, declaratory, and injunctive relief.
The appeal from the costs award was allowed, with no costs ordered either below or on appeal.
