The case of Mrs. Johnstone's estate stands in a different position. Of course she could take no better title than Mrs. Hage had. But, as against her, it must be proved what the defect in that title was. The question here arising is one of evidence only. There is no direct evidence whatever in the case to show that the appointor had any sinister or unauthorized purpose in appointing to Mrs. Hage. There is evidence of her having expressed her preference for Mrs. Hage over the other objects of the power, by reason of Mrs. Hage, alone among those objects, not resisting Mrs. Falstedt's desire to have the property sold. That tells in favour of the appointment so far as it goes. But the invalidating evidence consists purely in admissions by Redman and Mrs. Hage, which, however cogent against them personally were not in any way admissible against another person unless brought within some recognized exception from the general rule that all evidence must be direct and on oath (Spargo v. Brown[6], per Bayley J.). One exception, and the only one that could have relevance to this case, is that admissions made against interest by a predecessor in title are admitted against a defendant on the ground of privity of estate (Woolway v. Rowe[7]; and see also Llanover v. Homfray[8]). But Mrs. Hage is not proved to have made the admissions when she had any interest in the property. The only date of her admission fixed with anything approaching definiteness is 1901, that is three years before Mrs. Falstedt's will was made and eleven years before it took effect. When the admission was made, and, indeed, when the so-called assignment to Bernadetta Johnstone was executed, Mrs. Hage had only an expectancy. That expectancy constituted no interest whatever in the property (In re Parsons[9]). Consequently the case does not fall within the exception of privity. Further, it is established beyond question that where there is an assignment in equity of a purely equitable interest, the assignee, and the assignee alone, is regarded in the eye of a Court of Equity as having any interest whatever in the property assigned. So clear is this that the assignor in such circumstances is not only not a necessary, but not even a proper, plaintiff and his joinder as such was at one time, and before the later procedure provisions as to misjoinder, fatal to the suit (Fulham v. McCarthy[10], per Cottenham L.C.).
