There is something missing in your story.
You can’t be taken to NCAT for voting against a motion. Is there something else that they took you to NCAT for?
Did you or the secretary initiate the action in NCAT?
And it’s unusual that you would not have been notified of the court dates.
if you or the secretary were the initiator of the action, and then don’t turn up to court – well the courts do not look at such conduct favourably, and as well as getting a judgement against you they will penalise you by awarding costs against you
Perhaps a better explanation of what the events were could help us to help you.
