It seems like this is an issue of the strategy to use, rather than the law. Yes, at a subsequent General Meeting, the owners can overturn or alter a previous resolutions. It is the Strata Committee that puts the motion into effect, but until they act, then the building can change its mind.
But you need to decide what outcome you want, and rally the other owners to agree with that; or at least sufficient of them, to attend a General Meeting – or provide a proxy – and vote in favour of your solution.
Put together a proposal, which will give you the desired result, and discuss it with all the other owners who will help you – email them, or phone them, if you don’t know them. Work out new motions, and then ask the Secretary to call a General Meeting, for the proposed motions. If the Secretary refuses, then a quarter of the owners can bring it on, instead.
Get the numbers on your side, and you will get the result you’d prefer. But, you normally will need to organise before the meeting, the chances of swaying votes at the meeting usually are slim – people will have made their minds up already, and the Strata Committee will be committed to a course of action, and they will attend the meeting, and their numbers, if no-one else comes who is motivated to alter the situation, will be determining. Remember that you, or the Committee, can obtain proxies from people not willing to attend in person.
