Is the Chair a resident? I know it makes no difference to the law and its compliance, just how far removed he may be after sacking from Chairman. Will he still be on the SC.
For the Strata to remove a SC member, a general meeting with successful special resolution (75%) is required, or
The Tribunal under Sect 238 on application of an interested person, may remove a person from the committee, or office, or both.
But I trust you know this from your lawyer.
