81 Application of the principles gleaned from the foregoing authorities leads me to conclude that the application for an amendment should be refused. A caveat is a statutory injunction to preserve the status quo until the Court can determine the competing claims. It "operates as notice to all the world that the registered proprietor's title is subject to the equitable interest alleged in the caveat", per Griffith CJ in Butler v Fairclough [1917] HCA 9; (1917) 23 CLR 78. The estate is claimed by the respondent as "registered proprietor". That estate is said to be claimed by virtue of "an estate in fee simple". There is no hint of the basis upon which that estate is claimed, apart from the assertion that the respondent is the registered proprietor. There is no word in the caveat about a mortgage (apart from the oblique inclusion of "including transfer of power of S" in the dealings it seeks to forbid), nor any word about an unpaid vendor. To permit an amendment in any one of the five alternative terms proposed would be to entirely change the whole of the caveat and create an entirely new caveat. Whilst I am prepared to accept that the Act, s133(2), empowers amendment of a caveat, that power does not extend to entirely re-drafting the caveat to create a document that was not registered in the Office of the Recorder of Titles. Even if one or more of the amendments sought were made, that would not be sufficient for there would need to be consequential amendments, in one case to the part of land affected by the caveat, and in the others with respect to the dealings that are forbidden. A caveat is not, as Barrett J said in Multi-Span, "ambulatory or flexible means of maintaining a blocking position in aid of whatever interest, if any, the caveator may have from time to time", nor, I might add, whatever interest he might be able to argue that he has when he is forced to go to court to retain his caveat. Finally, I would add that in any event, proposed amentments (2) and (3) should not be allowed because there is no arguable case to sustain the interests claimed for the reasons given at the beginning of this judgment.
