I don’t know what High Court case they are talking about-they didn’t give a citation just a vague recollection-they might be remembering wrong.
But the assumption in the Torrens system is the government database is correct. There are rare exceptions-e.g. the so-called “paramount interests”-but they are narrow and very much exceptional. By contrast, in the US system, a court is totally open to entertaining the argument the county title records are incorrect, in many states there is no presumption against such an argument, and you aren’t required to convince the court some narrowly drawn exception applies before it will consider the argument. (Actually Australia still has something like the “US system” too-we call it “old title”-but old title is extremely rare. Anyone trying to sell an old title lot is going to convert it to Torrens before selling it. I don’t think you can legally sell it until you do so. So in practice the only old title lots left are those which haven’t changed ownership-other than by inheritance-in many decades.)
> Second, since there is no single government for the entire world, any government trying to implement a Torrens system is still going to face the problem of events happening outside its jurisdiction that its records do not and cannot contain, which affect ownership of property in its jurisdiction.
That’s not how it works. Overseas contracts, court judgements, etc - if you don’t lodge them with the land title registry, they don’t legally exist as far as land titles go.
