Rhm, know your despair!
Don’t know how different the Strata management schemes ACT is to the NSW one but quite recently decisions have been appealed and overturned in NSW which has worked out in favour of the Owner against the Owner’s Corp. The case is Shum V. Owners Corp ( can’t remember Sp number ). There is an article in a Bannermans Lawyers website which mentions proceeding with the Tort of Nuisance against the OC. Cordata Partners had some encouraging articles too.
