unauthorised renovations by committee member

So, a committee member ripped out her kitchen, converted her laundry to a shower,added an extra toilet, added a sink and tap to the small balcony.erected walls in her former living room. This is in a 1974 built two BR unit. We put a motion in the AGM to have the renos retrospectively assessed and corrected. When it came time to elect the Strata Committee, she put up her hand.in disbelief I objected to someone who should have known better being on the committee.the Strata Agent ( a well known about town Strata business) disappointedly adviced us there was nothing that can be done. If she had been in arrears then that would have been the only valid reason to kick her off. Has anyone had similar experiences?
