bim – all Owners should (actually must) be provided with the Minutes of the immediately preceding General Meeting, and any of those who submitted a Proxy Form prior to the commencement of that most recent AGM and like you had issues with those previously issued Minutes should have used the provision on the Form to direct their Appointed Proxy to vote as you did; that is against the Motion for acceptance.
Obviously for whatever reasons some absent Owners didn’t see any problem with the Minutes, and so the Motion to accept those as a true and accurate record was properly passed by a majority vote of those present and entitled to vote at the AGM, that is both personally and by proxy.
