[1979] 1 WLR 247 (CA). A Testator left his whole estate on trust to support his elderly mother and pay for his daughter's university education. After the mother had died and the daughter graduated, the question arose what should happen to the surplus of the trust fund once its purposes had been fulfilled. On the principle established in re abbott (1900), it could be argued that the surplus should be held on resulting trust for the estate of the testator. However, in Abbott there were no surviving beneficiaries, so such an outcome was not particular unjust. In Osaba [[Court of Appeal] held that the words of the testator's will could be construed in such a way that the daughter was entitled to the continued benefit of the trust, which would be giving effect to the testator's true wishes (which, presumably, he didn't express very clearly in the will). It's unlikely that this approach would be taken if there were no surviving beneficiaries (as in Abbott), or even if there were multiple surviving beneficiaries and allocation of the benefit would be difficult.
