To your first question on the process, I think it was mentioned a bit earlier that all of the applicants have due process rights, of course. What we tend to see is the removals end of the process. It may take three or four years to actually come into place, because by the time a person goes through the process and is ready for removal, there are various, as you mentioned, levels of appeal and so on. That's what we deal with now. So when we look at removals that we're doing this year, they probably reflect an influx from about three or four years ago.
I'll perhaps leave it to my colleague to talk about the pre-removal risk assessment, if he would like. That's provided by CIC to us.
Regarding improvements, well, we're always anxious to follow the act and remove as soon as reasonably practicable whenever a person is removal ready. But of course we respect the due process and wait for that to unfold before we can actually do that.
