I will come to that point, but I will say now that the Prime Minister’s red lines, one of which was the ECJ, may well prove to have been reckless. The EU insists on treaty arrangements governing key aspects of international security, justice and policing, as do we. Without a treaty, courts have no legal basis to implement arrest or extradition warrants and cannot allow third countries access to criminal and other databases. We are on course to become a third country in our relationship with the EU. Because there is no security treaty planned or even aimed for in the exit documents, the level of co-operation between the UK and the EU post Brexit could be severely and unavoidably downgraded.
Ministers will be aware that neither France nor Germany will automatically extradite to non-EU countries—their constitutions say that. There will be a mutual loss of the use of the European arrest warrant, and the UK will no longer be able to access the Europol database in real time. In addition, as a third country, the UK’s access to databases of criminal records, fingerprints, DNA and missing and wanted persons will be compromised. Ministers promise a future security partnership between this country and the EU. However, the assurance on access to SIS II and the European criminal records information system is only that
“the UK and the EU have agreed to consider further how to deliver capabilities that, as far as technically and legally possible, approximate those enabled by EU mechanisms”.
That is not the same as assuring us of the same level of co-operation that we have today. In relation to the European arrest warrant, there is not even that promise. On passenger name records and the exchange of DNA, fingerprints, and vehicle registration, the agreement says:
“The UK and the EU have agreed to establish reciprocal arrangements”.
It does not say that they have established reciprocal arrangements; it is a wish for the future. However, without appeal and oversight by a court—that role is currently played by the ECJ—all these things could be subject to legal challenge in practice.
