Thank you both kiwipaul & Whale. Due to the requirement of 5 year archival of strata documents, we are unlikely to be able to discover whether there were any resolutions regarding the additions at all. Unless of course, the individual owners are required to hold on to the permission/agreement documents as proof the works were approved. Does anyone know?
On a different note, there may be a way to equalise this situation where individual owners make additions & the rest of us are saddled with their maintenance. A strata lot owner with deep pockets, living in a similar situation anywhere in NSW could lodge an application at the Tribunal to demand that all lot owners in that strata must have the same alterations in order to preserve the pleasing uniformity of its appearance, therefore its value. Further, all such construction expenses be paid by its sinking fund & any related maintenance paid out of the admin fund just like the others, who, while they might have paid for their alterations, would have had the benefit of free maintenance out of the common funds over the years. The success of such an application would also benefit the incumbent government of the time that the purported fairness of its strata laws are there for all to see. Failing that, the application itself would be noticed widely, especially with a little help from the applicant, along with other interested parties in similar situations, creating a very, very important precedent. Since our legal system runs on precedents, even in minutely prescribed laws, it would make little difference whether the initial application were successful. I can just see the SPs lining up at the Tribunal. It would be interesting to hear from the specialist lawyers who read this forum. And dear Strata gurus, please pause a while before you attack your keyboards to call me a harebrained idiot.
