79 The Bank further argues that the system of indefeasibility of title, created by the Transfer of Land Act 1893, as explained in Breskvar v Wall (1971) 126 CLR 376, protects the Bank in the exercise of its power of sale under the mortgage in circumstances such as these. The Bank contends that, whilst the Society remained the registered proprietor, albeit under a defeasible title in the face of the allegations of error or fraud, the Society could, nonetheless, create a valid interest in third parties such as the Bank. Therefore, even if the Bank had granted a mortgage to the Society whilst the Society was the registered proprietor, and had the mortgage been registered prior to the Church's caveat being lodged, the Bank's legal mortgage would take precedence over the Church's equitable interest that is the right to reconveyance of the property. They, of course, are not the facts here. Thus, the Bank argues that this case is much stronger than suggested in this hypothetical example, because the Church itself granted the mortgage when it was indisputably the registered proprietor and before the alleged fraud was perpetrated. The subsequent disputed transfer of title was subject to the Bank's existing legal interest as mortgagee. Thus, the Bank contends, if the land were to be reconveyed to the Church, it would be reconveyed subject to the Bank's mortgage and the Church, as mortgagor, would still be in default under that mortgage.
