Look, at the moment we're talking around the preamble. I suppose my question to the member is very simply: why do we have a preamble? This is highly, highly unusual and I'm not trying to be completely flippant. Sorry, there's always an element of flippancy in my speeches. But why do we have a preamble I think would be helpful to know, because when I do think of preambles I turn my mind to such august documents as the Constitution of the United States, the Declaration of Independence. And I'm just wondering whether the member in the seat does see that there's some convergence between those great constitutional documents and this amendment bill.
