Any correspondence between anyone and the owners corp is able to be viewed by owners . To give an extreme example, a couple of years ago the strata committee of my building got into a nasty dispute with a former employee which ended up in a court-ordered settlement with the judgement “sealed” by the court – i.e. it wasn’t to be made available to the public.
Even so, a couple of owners were able to go to the strata manager’s office and view the document, albeit under tight supervision. The thing is, as members of the owners corp, they were parties to the dispute and therefor permitted to read the judgement. Thers is privacy in owners corpp correspondence, as far as owners are concerned.
