SlapShot – Sorry, but I can’t help thinking that you have a personal interest in the insurance claim and/or the individual/s concerned, and whilst I’m not suggesting that’s improper (because I don’t know the details), I must say that even a person as dogmatic as me would now let it go! After all, the claim’s been accepted and paid (and it’s not big $), and both the Owners Corporation (O/C) and its Insurers have resolved improperly or otherwise that the matter is closed.
That said, I can understand why you’re annoyed at the underhanded and deceptive way in which your Executive Committee has behaved, and the only way that I know of to handle that in NSW is to seek the intervention of the Strata Division of the Consumer Trader and Tenancy Tribunal (CTTT) by way of Orders under S156 of the Strata Schemes Management Act (1996) for the O/C to supply all documentation to do with the Insurance Claim.
That process involves mediation as a mandatory first step, and if unsuccessful the process escalates as you’ll see HERE, but it should result in Orders for the O/C to provide you with the documentation that you seek.
Once you have that documentation, and if it’s as damning as you suggest, then you could use it to yourself lobby other Owners in an effort to seek sufficient support to then requisition a General Meeting to censure the members of the Executive Committee, and to elect a new one that will better represent the Owners.
Other posts may assist you further, but good luck with whatever you decide to do.
