In England, Wales and Northern Ireland, only “designated” Ministers and departments can exercise powers in section 2(2) of the European Communities Act 1972 (c.68) to make orders, rules, regulations and schemes. This is one of a series of Orders by which the Ministers and departments are designated for the purposes of section 2(2) in relation to different subject areas.
