Should This Vax Mandate Aussie Psycho Be Sued?

However, shouldn't the lawsuit be expanded to include the mental case former Chief Minister of the Northern Territory who ranted like a lunatic about forcing vaccine mandates on everyone in his jurisdiction? This official, Michael Gunner, was forced to resign in humiliation in 2022 due to the vaccines NOT stopping the transmission of Covid nor preventing Covid in those who were already vaccinated.
