In Qld, as I understand it, you can only sue the Secretary, and that is for defamation if they make some grand yet damaging incorrect public or written statement about someone affected. The rest, as generally being well-intentioned amateurs, can’t be. Though their actions can be over-turned by another vote by the committee or your states commissioner or through a EGM if you have enough owners (25%?) who call it to overturn it.
