Surely the Strata Manager has some sort of professional (huh!) duty to properly record issues….
The strata manager can only act on the information given to them by the committee.
The clear breach here is an alleged deliberate attempt by an owner in a privileged position to conceal the true status of repairs required in the building. I am no expert in conveyancing law but i would say that was probably illegal.
If committee members have colluded in this (with the intention of doing so themselves) then they have lost their individual indemnity by not acting in good faith.
But if you go after the committee members as well as the vendor, they will all claim there were no discussions.
Talk to a solicitor then, if they agree, focus on the vendor and get evidence from the other committee members to back you up.
I doubt very much if the strata scheme as an entity (rather than individual members) has any liability.
