I just draw my right hon. and learned Friend’s attention to paragraph 1(2)(c) of part 1 of schedule 7, which would require that the affirmative be used if a provision
“provides for any function of an EU entity or public authority in a member State of making an instrument of a legislative character to be exercisable instead by a public authority in the United Kingdom”.
So instruments of a legislative character coming across would trigger the affirmative.
