Surely the Owners Corp can make this problem go away by adjusting the light!
Just for clarity: if OC is represented by strata manager and I lose, the strata still need cost orders to bill me?
Read your strata management contract. Strata managers can add extra charges to their contract. e.g. a $5 fee for overdue levy payment. My (former) strata manager charged $440 for appearing at NCAT for half a day.
Otherwise, the document linked in Jimmy’s post makes it clear that only NCAT determines who pays for costs. You have to put that request in your application.
This is also true for a breach of by-law: the owners corporation may NOT order the owner to pay a fine. The order is made by NCAT.
