European Union (Amendment) Bill

As an aside, I recommend to every Member a recent book on the Putney debates, written by a member of staff who works for an MP. Does the hon. Gentleman accept that whenever the European Court of Justice has confronted a constitutional court head-on, so far it has always backed off? The real problem is that we do not have a similar buffer line to say that a decision goes against our constitutional structure, and I am not entirely sure that the hon. Gentleman's amendment would achieve that either.
