What sorts of decisions are the committee making that you disapprove of? I am more familiar with the ACT act than those of other states but I expect they have provisions similar to the ACT. Here certain sorts of decisions can only be made by a general meeting. So, for example, if the act says a decision requires an ordinary resolution of the owners corporation, it is not within the power of the committee to decide. Some matters are covered by rules (aka bylaws or articles), rather than the body of the Act. In those cases, the OC might have resolved to amend those rules in a way that delegates a decision making power to the committee. However, the scope for doing that is limited. Some things cannot be delegated to the committee, even in if the OC wants to because the act says the OC must decide by a particular class of resolution, and that means a general meeting.
