Is the Home Secretary aware of the European Union Act 2011 in the context of what is required for a referendum? Section 4(1)(i) refers to
“the conferring on an EU institution or body of power to impose a requirement or obligation on the United Kingdom”;
while (j) refers to
“the conferring on an EU institution or body of new or extended power to impose sanctions on the United Kingdom”.
Surely an opt-in to the various 35 measures will do that and should trigger a referendum.
