So others have done that pretty well—or very well, actually, I should say—and I don't intend to rehearse the points that they've made. The Hon Judith Collins made the point I think very astutely that it will be changed in the future. It will need to be adapted, it will need to be amended. That's common enough with Acts of Parliament. The law changes; practice changes. And of course the reason in this case we can say with confidence that there will be change is because the technology that underlies the legislation itself will change.
