This case is significant for establishing the approach to costs orders where an appeal involves severable issues with divided success. It demonstrates the court's discretion to apportion costs based on the relative weight and success of distinct issues, rather than applying an all-or-nothing approach. The judgment provides important guidance on how courts should exercise their discretion in complex multi-issue appeals, considering factors such as: the substantive importance of different issues (measured by amounts at stake), the time and resources devoted to each issue, and the degree of success achieved on each severable ground. It affirms that partial costs orders are appropriate where they better reflect the justice of the matter than either full costs awards or no order as to costs.
