(4) Regulations under this section may only be made with the consent of the local authorities to whom the regulations apply (subject to subsection (5)). (5) Regulations under this section, so far as including structural or boundary provision in relation to a non-unitary district council area, may be made if at least one relevant local authority consents… (8) Subsections (5) to (7) expire at the end of March 2019 (but without affecting any regulations already made under this section by virtue of section (5)).

“A proposal made by any of the relevant authorities before the date that these Regulations come into force that otherwise complies with section 2 of the 2007 Act (as modified by these Regulations) shall be treated as a proposal made under that section.”
“43. I have concluded that the delegated legislation proposed in the consultation of October 31, 2011 would have retrospective effect in respect of any installation becoming eligible for payment prior to the modification coming into effect, as proposed on April 1, 2012. Such legislation would only be valid if the empowering provision contained in s.41 of the 2008 Act authorises such an effect. Just as there is a presumption against retrospective operation in the construction of statutes, so there is a presumption in relation to the construction of a statute delegating legislative powers. Indeed, the authors of de Smith’s Judicial Review, 6th edn, suggest that the presumption is even stronger in relation to the powers conferred by delegated legislation (5–040, in reliance upon Newcastle Breweries v The King [1920] 1 K.B. 854; (1920) 2 Ll. L. Rep. 236 KBD at 865). Absent a clear provision conferring power to make retrospective delegated legislation, the assumption of such a power offends the legality principle.”
“44. In Wilson v First County Trust Limited (No.2)[2003] UKHL 40 ; [2004] 1 A.C. 816 at [19] Lord Nicholls adopted the principle expressed by Staughton LJ in Secretary of State for Social Security v Tunnicliffe [1991] 2 All E.R. 712; (1992) 4 Admin. L.R. 57 CA (Civ Div) at 724: “The true principle is that Parliament is presumed not to have intended to alter the law applicable to past events and transactions in a manner which is unfair to those concerned in them, unless a contrary intention appears. It is not simply a question of classifying an enactment as retrospective or not retrospective. Rather it may well be a matter of degree – the greater the unfairness, the more it is to be expected that Parliament will make it clear if that is intended.”
