[3] Ordinarily, the fact that a successful plaintiff or applicant fails on particular arguments does not mean that he should be deprived of some of its costs or require an apportionment of costs between issues.[2] However, there are two features in the present case which, in my conclusion, warrant a departure from the general rule. The first is that most of the factual questions pursued by the applicant were bound to be inconsequential. In particular, there was the applicant's case that there was no rational basis for quantifying the special charges in the total of $3,600, because the actual cost of the works, so the applicant alleged, was $3,076.52. As I held, the validity of the decision did not depend upon the accuracy of the Council's estimate of the cost of the works. Indisputably, the Council had received an estimate which it accepted. The cost of preparing and presenting evidence as to this false issue could not have been insignificant. The second consideration is the amount of the special charges which were challenged in these proceedings. The applicant brought these proceedings for a monetary gain of but $3,600 (with some small interest component). His case did involve a matter of general importance and he should not be denied his costs simply because of the small value to him of the outcome. But this consideration makes it more difficult to accept as reasonable the way in which the applicant's case was pleaded and argued, because the introduction of false factual enquiries is to be particularly discouraged where the resulting legal costs would indeed be greater than the worth of the plaintiff's cause of action.
