(1) The general rule is that costs should follow the event. Absent disqualifying conduct, the successful party should recover its costs even where it has not succeeded on all heads of claim.
(2) The Rules of Court permit significant flexibility in determining questions of costs. In particular, the Court is entitled to examine the realities of the case and will attempt to do 'substantial justice' as between the parties on matters of costs.
(3) Where there is a multiplicity of issues and mixed success has been enjoyed by the parties, a Court may take a pragmatic approach in framing the order for costs, taking into consideration the success (or lack of success) of the parties on an issues basis. Generally, if such an order is made, it is reflected in the successful party being awarded a proportion of its costs but not the full amount.
(4) A Court may, when fixing costs in a claim where there has been mixed success, take into account complications which it considers will arise in the taxation of costs, as part of its consideration of the overall interests of justice.
(5) Where a Court determines to make an order apportioning costs, then it does so primarily as 'a matter of impression and evaluation,' rather than with arithmetical precision, having considered the importance of the matters upon which the parties have been successful or unsuccessful, the time occupied and the ambit of the submissions made, as well as any other relevant matter.
(6) Where a number of parties have had the same representation, there is a 'rule of thumb' as to the apportionment of costs, namely that, where some of those parties have been successful and others have not, each successful party is only entitled to his or her proportion of the costs incurred on behalf of all, plus the costs, if any, incurred exclusively on his or her behalf. The primary issue for determination in such a case is that of fairness as between the parties, having regard to the manner in which the trial, or appeal, has been conducted.
(7) Usually, an order for costs will be made on a party/party basis. But an order for costs on a solicitor/client or indemnity basis may be made where special or unusual circumstances have been demonstrated, for example, by establishing misconduct in the proceeding, that the proceeding was brought for an ulterior purpose, or that it was patently unreasonable to institute, or maintain, the proceeding. Special circumstances may also include the making of an allegation of fraud which is not proved. (footnotes omitted)[20]
