The Commonwealth argued that the laws made no unjust acquisition of property, since broadcasting licences were not immune to being modified by the Parliament. They said that it was fair and just to require broadcasters to provide a limited amount of free service in the public interest. In any event, the Commonwealth suggested that "free time" granted by the Act was not a form of property anyway, since it could not be transferred to other people, one of the essential features of any form of property.
