Another case in my backlog for some time, and thank you Sarah McKibbing for flagging, some time back,  VSC 810 Liu v Ma,
At 6 Mukhtar AJS notes ‘There is sufficient authority for the view that Australian Courts will enforce a foreign judgment where the defendant is a subject of the foreign country in which the judgment was obtained. That view has its critics (footnote omitted, GAVC) and it may have its difficulties especially if the citizenship is inactive. Nevertheless, it is founded on a line of English authority exemplified by the statement of Buckley LJ in Emanuel v Symon‘.
Many would argue that at the very jurisdictional level nationality as a ground is parochial /exorbitant. At the same time that at the level of recognition, one should show restraint in refusing to recognise judgments based on such flimsy jurisdictional grounds.
For those wanting to dig deeper, prof Andrew Dickinson has critical review of the relevant case-law in (2018) 134(July) LQR 426-449 (‘Schibsby v Westenholz and the recognition and enforcement of judgments in England’).
