The situation here is exactly analogous to that in Australia, which has been working successfully for 10 years.
The other point in this debate, in reference to the interesting amendment from the noble and learned Lord, Lord Hope, is the importance of the monitoring. I agree with him and the noble Lord, Lord Anderson, that the more transparent and obvious this is, the better it will be for everyone. Fundamentally, we cannot expect the law to do everything. We all know that there are many laws which are not adhered to in practice. It may go wrong on the ground floor in a way that lawyers, for all that has been said in the treaty, are not aware of until it is too late. You therefore need a strong monitoring committee whose information is available to this House and the general public, because you cannot do it any other way. The law cannot encompass what may happen in future.
That is a crucial point from this debate. I would have thought that my noble friend the Minister could accommodate the relative transparency of the monitoring committee, which has independent people on it. The noble Lord, Lord Kerr, may not like some of them because they disagree with him, but the committee is none the less independent. Precisely because of that, it will have people of differing views. The Government should look at that in response to the tone of this debate.
