Senator MILNE (Tasmania—Leader of the Australian Greens) (14:20): Mr President, I ask a supplementary question. Given the Prime Minister's abhorrence of environmental regulation or so-called green tape and his desire to hand over environmental powers to the states, who would oversee compliance and enforcement of regulatory measures to implement Direct Action when it fails to secure legislative approval? The PRESIDENT: Senator Milne, that is hypothetical. I will give you, as I have given others, the opportunity to rephrase your question. Senator MILNE: Thank you, Mr President. I rephrase it by asking: will the government implement Direct Action through environmental regulation or so-called green tape?
