We always have General Business as an agenda item. I did clarify that it could not be voted on unless it was a specific item already raised. I thought that was fairly clear. An AGM where no one could raise general business would be fairly worthless. Often many owners never have input with the exception of the AGM.
Again if it is a matter of removing locks for maintenance then there are no rules. As far as fire requirements then having no locks would not be against the law. This discussion confuses the situation. As long as the door is auto-closing to prevent it staying opening and facilitating fire travelling then it is compliant. Was the OP discussing fire or security? If it is security then that is a building matter. If the locks prevent people from exiting then it is another matter. I know of buildings that have a self-closing, non-lockable door only and they are fire certified. If the OP is talking about security we should keep to that unless the fire requirements are impacted by the changes.
