“(12)… I have considered the alternative open to the appellant. Had [the surveyor acting for the appellant] appeared at the hearing, there is nothing to suggest that costs would have been awarded against the appellant, even had the VO been wholly successful on the substantive issue. The VO would, in all likelihood, not have recouped the costs of the preparation of his expert report. In fact, by withdrawing the case the appellant had saved costs both for themselves and the respondent.”
“ ‘Unreasonable’ … means what it has been understood to mean in this context for at least half a century. The expression aptly describes conduct which is vexatious, designed to harass the other side rather than advance the resolution of the case, and it makes no difference that the conduct is the product of excessive zeal and not improper motive. But conduct cannot be described as unreasonable simply because it leads in the event to an unsuccessful result or because other more cautious legal representatives would have acted differently. The acid test is whether the conduct permits of a reasonable explanation. If so, the course adopted may be regarded as optimistic and as reflecting on a practitioner’s judgment, but it is not unreasonable.”
