Upon an ordinary claim in the general jurisdiction it is, generally speaking, obvious who has won and who has lost, and correspondingly clear why costs usually follow the event. Upon a claim for compensation for land compulsorily acquired, it is not, generally speaking, appropriate to speak of one party as having won; compensation is awarded to one who has already been given, by statute, the right to receive it. It is therefore as just to say of the latter sort of case that the claimant ought, in the absence of special circumstances, to receive his reasonable costs of obtaining the compensation that is, ex hypothesi, his due, as it is to say of the former sort of case that prima facie costs follow the event in favour of the party who has won. But costs are, as always, discretionary, and no hard and fast rule will ever be allowed to occupy part of an area controlled by a discretion, however predictable the result of its exercise may be in certain sorts of cases. . . .Against the history of a wide-ranging discretion given to this Court with respect to costs, I am, I apprehend, to construe s. 36 flexibly and not restrictively, to the intent that the special nature of the jurisdiction to which it relates should be duly recognized, and orders made in that jurisdiction that are just and expedient.
