Senator O'Rourke referred to the jury system, of which I am passionately in favour. The Senator wondered about the kind of training available to members of juries who bring to their task a common sense approach derived from their life experiences. The jury system is not a hangover of medieval English law. The great strength of the common law system, on which our system is founded, is that it is based on arbitration between the individual and the State in which both are equal.
