Where I part company with the Government is in believing that it would not be better to make these adjustments in the current structure, rather than under the new structure, and to negotiate to maintain the current structure with our European partners, because as it currently stands, if we change the law, that is the law of the land. Once we have opted in, it is not: the law of the land is subject to the European Court of Justice.
Then there is the issue of double criminality. The European Commission’s website, in explaining how the arrest warrant works, says quite clearly:
“If they are punishable in the issuing Member State by a custodial sentence of at least three years, the following offences”—
which are then listed—
“may give rise to surrender without verification of the double criminality of the act”.
Therefore, although we may pass a law saying that double criminality is a requirement before we extradite somebody, the rule of Brussels is not so. Now, in the situation we are currently in, our law is superior, but then their law will be superior.
