Well, aside from the fact that local councils are NOT recognised by the constitution and are operating as illegal entities, they have no right to take your property. They also have no right to impose a fine on you.
Local councils are getting away with far too much, look up a guy by the name of Wayne Glew, he gives his mobile number and email address in his interviews on youtube. Send him the story and ask his advice, he is an expert on the constitution and is on a bit of a crusade agaisnt governments and local councils shafting us.
