The respondent argued that the new Loyalty Program implemented by the appellant was oppressive and unfairly prejudicial to its grocery business interests. The appellant claimed financial losses and operational disruptions from the respondent’s decision.

It contended that the decision was inappropriate, and the damages remedy was excessive....
