Oh dear this has been labelled a coup, or as one owner always calls it, a coo.
The OP forgot to mention that they were the one who made the application to NCAT and included 2 deceased persons as supporting the application. The OP also forgot to mention they provided one version of the application to NCAT and another version to the owners. Unlike what the OP writes, the secretary never said the owners were neutral, it was NCAT which stated the Owners Corporation would be neutral. NCAT actually encouraged individual owners to participate in the matter if they wanted to.
The OP should really get their ducts in a row.
