How have courts dealt with costs in personal injury cases?

Cases such as Liu v. Hanson, (1995) 38 C.P.C. (3d) 398 (B.C.S.C.), cited by the petitioner, are of no assistance. That case dealt with an order that included a provision for costs in favor of one party. About a year later an attempt was made to have the trial judge make a change to the substance of his order regarding costs. The court said it was functus, having actually considered, rendered a decision and signed an order reflecting exactly what he intended. The proper action was, in that case, an appeal. I see no similarity on the facts between that case and the one before me in which the costs issue was neither addressed by counsel nor by the court in its decision or order.
