The convicted killer of Philip Lawrence is obviously a horrible individual who is deservedly subject to a life sentence. EC legislation (if that is what the Asylum and Immigration Tribunal has applied in its recent judgment) would only permit him to be expelled back to Italy if he is a threat to national security. But this has nothing to do with his life sentence -- EC law has no impact on that. It is even possible that the UK system will be less lenient in permitting his future release than the Italian system. If the UK penal system never releases this murderer from his life sentence, that would be fine by me.
But is it wrong in principle that EC law does not allow his deportation? (Perhaps the tribunal was relying on the Human Rights Act; in that case the outcome is not so clearly required by Strasbourg case law). Obviously this is a difficult case, but the EC legislation strikes the correct balance. Once someone is on the territory of a Member State for over ten years, it makes sense that the concept of EU citizenship transfers responsibility for that person -- except in national security cases -- to the host State. This in no way restricts the prosecution and sentencing of individuals if they are found guilty of serious crimes.
One thing that is clear is that this is a matter of free movement law, not JHA law, since the person in question is an Italian man who is relying on an EC Directive (not adopted by the Commission, but by the Council and EP).
Open Europe is therefore wrong to make comparisons with JHA law:
This case has nothing to do with asylum legislation, the rights of suspects, the European supervision order, or the prohibition of double jeopardy in the Charter. In any case, the UK could either veto or opt out of these legislative measures at present, or opt out of them under the Reform Treaty, and the UK's opt-out from the Charter quite clearly would mean that our law on double jeopardy would not be affected (in any case, there are exceptions to the double jeopardy principle, as set out in the relevant Protocol to the ECHR and which can be assumed to be incorporated into the Charter).
