So his remarks were also very well prepared, for which I give him credit.
Earlier, the Home Secretary responded to me on the issue of whether the opt-ins under the justice and home affairs provisions—if indeed we have opt-ins now—would trigger a referendum. She shared her view that they would not, but she did not give reasons and I do not believe she spoke to the specifics of the point. The European Union Act 2011 was ably taken through the House by the Minister for Europe, whom I am delighted to see in his place—he may be able to correct or assist me, or perhaps share some of the Government’s legal insight, which has eluded me to date on this issue. Section 4(1) deals with triggers for a referendum, and paragraph (i) refers to
“the conferring on an EU institution or body of power to impose a requirement or obligation on the United Kingdom”.
An even clearer trigger is section 4(1)(j), which refers to
“the conferring on an EU institution or body of new or extended power to impose sanctions on the United Kingdom”.
It strikes me that with those opt-ins, the Commission would have the right to enforcement action, and the European Court of Justice potentially to deliver fines.
