Senator MILNE (Tasmania—Leader of the Australian Greens) (14:19): My question is to Senator Evans, the Minister representing the Prime Minister. Given that the Tasmanian House of Assembly has passed the Greens bill enabling equal access to marriage for same-sex couples, in the event of that legislation passing the upper house will the government rule out a High Court challenge to the validity of that law; and, further, will the government rule out any clarifying legislation that would seek to invalidate such state law?
