Dear Paradise
before a compulsory strata manager is appointed , you have to prove your case.
I note in your question you mention a number of issues which seem to relate to the administration.
You would need to list every single indiscretion and prove that there was some maladministration. Hear say will not win the case.
And remember that just because you dont like the way things are done, does not make them illegal.
You would also need to provide evidence where you have pointed out this maladministration to the OC/committee/strata manager, and to have their responses (even non responses) Otherwise the tribunal will just tell you to sort it out, and if you cant sort it out come back another day.
