Senator BOB BROWN (Tasmania—Leader of the Australian Greens) (14:10): Mr President, I ask a supplementary question. Is it within the ambit of CAD to be able to make legal adjudication on advertisements? Is it not its job to determine classification? Is it not the job of commercial stations themselves to determine what may be actionable and what may not? There has been no public or extant ruling against this advertisement by GetUp! by reason of legality.
