The BC and EC do have a duty to enforce the bylaws. Here is a quote from the NSW Strata website.
Owners corporations also have the following powers and obligations:
-
To issue a notice on a person to comply with a by-law, when the owners corporation or its executive committee passes a resolution that there has been a contravention of the by-law in question.
Problem is their is no way of forcing them to do anything.
As the other poster said I believe you can initiate action yourself. Here is the web site:
