Direct from the judgement
19. By mid-March 2020, as a result of:
(i) the collapse in passenger travel;
(ii) measures implemented domestically and internationally to restrict movement;
(iii) the increasing concern that the effects of the COVID-19 pandemic would be sustained; and
(iv) uncertainty as to how long the effects of the COVID-19 pandemic would last,
This, to an albeit untrained legal eye, would suggest that ending of border closures alone would not be sufficient to end stand downs. A return to near normal passenger numbers and an ending of the pandemic would have to happen as well.
