At the directions hearing, the “rebels” could outline the case above and present it as an attempt to thwart the will of the Tribunal and ask that, if it happens, it should trigger a move to replace the committee with a statutory strata manager for the next two years.
That way you will get rid of your committee and strata manager in one fell swoop. This could still happen after the event, by the way, so it might be enough to let the committee and strata manager know that this is the plan.
There is a danger, however, that the person presenting this could come across as a little paranoid if they don’t have evidence of this plot to offer.
