On sovereignty, it looks as though the Prime Minister has done better than many expected, in that EU leaders have apparently agreed that the phrase “ever-closer union” should no longer serve as a signpost for integration. That is potentially very important, since the European Court has often made use of the phrase in advancing its more aggressively federalist judgments. But how bankable is this? Will it be engraved in the treaties? Will the court be obliged to take account of this change, or will it be blown away – like Tony Blair’s evanescent opt-out from the EU Charter of Fundamental Rights? How can we restore the force of that Lisbon opt-out, and stop the court making rulings on human rights? In asserting Parliament’s sovereignty, how can we construct something that will be truly intimidating both to the law-making activism of the commission and the judicial activism of the court? Are we talking bazooka or popgun?
