In my time I wanted to focus mostly, or at least initially, on the constitutional aspects. Others have made mention of these, but I think it's important to ensure that we all clearly understand—and, for what it's worth, place on the record—some thoughts about how the different branches have interacted in relation to, first, the passing of the law; its application, and, indeed, what we might broadly describe as the repeal process. Also, I did want to discuss different aims of the criminal justice system. It seems to me that often in these debates there's a conflation of different, but related, aims of the criminal justice system. I think it's fair to those who are arguing in favour of the regime actually to understand the benefit that such a sentencing regime can have beyond the tired old discussion about whether certain types of offending are likely to have a deterrent effect or not.
