I'll take that, because I think that's a political question.
I think that members of Parliament come to bring common sense to the development of laws. Otherwise you would have to be a lawyer to be a member of Parliament, and you don't. If people wanted to send only lawyers to Parliament, they would send only lawyers to Parliament. You are all here, from different backgrounds, to apply common sense. I think the vagueness is in the word “toxic” itself, because it applies to such a broad range of products, products that are very inherently toxic, but only in certain contexts. In some cases it's to the environment; in some cases it's to human health; in some cases it's with exposure over a long period of time in small amounts. In other cases the substances are acutely toxic. I think the vagueness is in the word “toxic” itself.
