There is a whole series of measures in respect of which it will make no difference whether we are in them or out of them. We have no objection to opting out of a series of redundant measures. However, there must be proper assurances and guarantees about the measures that we need to opt back into. Rather than a massive transfer of powers, this is, as the Prime Minister said, more like a massive transfer of hot air.
There is not the substance in this to justify the Home Secretary’s parade of historic significance and celebration of sovereignty.
Although the Home Secretary has not set out any major benefits from opting out of these measures, we know that there are risks to the serious measures where even she now admits we need to opt back in. She has no guarantees in place and no assurances from the Commission or the Council that at least on the most important measures—the arrest warrant, data sharing, joint investigations—we will be able to opt back in. She will know that the House of Lords pointed out that when Denmark exercised its opt-out,
“the Commission had frequently refused permission for the Danes to conclude agreements in certain areas”.
Nor has she any guarantee on the timetable or, for example, whether we will simultaneously be able to opt back into the European arrest warrant, whether there will be a gap in its operation, or whether complex or risky transitional arrangements will need to be negotiated.
Given how important the Home Secretary herself has said the European arrest warrant and various other measures are, surely it is important to ensure that there is no gap in operation. She can provide no assurance for the police that there will no interruption, therefore, of their use of the arrest warrant. The House of Lords report also said that
“the Government have not provided us with even a summary of the reactions of the other Member States to the Government’s intention to exercise the opt-out”
which
“may be critical in assessing the potential success or otherwise”
of the UK’s negotiation to rejoin particular measures. Surely on these most important measures she should seek assurances from the Commission and the Council before she asks this House to opt out .
