Worry not folks, Novak and his lawyers are saying that he has had Covid in December, therefore, that makes him immune to Australian Laws ----the mind boggles.
Going off this philosophy, it would appear that, if you have already had the virus, you can't get it again and you are immune to everything relating to the virus. BT, perhaps you could use this 'Novak Argument' to have your father-in-law realeased from hospital because ---according to Novak and his lawyers ---he could not possibly have caught the virus three times --no matter what ---once is enough!
