Section 141
(2) The change to the by-laws has no effect until—
(a) the owners corporation lodges a notice, in the approved form, with the Registrar- General, and
(b) the Registrar-General makes an appropriate recording of the notice in the folio of the Register for the common property for the scheme.
As the OC is an artificial entity (not a natural (real) person) it comes back to its assistant the SC to do this and if you want to go all the way arguably it comes back to the secretary, the elected or delegated secretary (agent), under s 43 (g) “to attend to matters of an administrative or secretarial nature in connection with the exercise of functions by the owners corporation or the strata committee of the owners corporation”
And you can’t charge the owner for the OC to perform a function of the OC. Well; you can and if the owner is silly enough to pay it then their bad.
