4(1)Regulations made under this Schedule may contain such supplementary and consequential provisions as the Secretary of State thinks necessary, including provisions as to the manner in which questions arising under the regulations are to be determined and provisions adapting, modifying or repealing enactments, whether of general or special application.
(2)Regulations made under this Schedule may be made so as to have effect from a date prior to their being made, but so much of any regulations as provides that any provision is to have effect from such a prior date shall not place any person, other than the Corporation or a publicly-owned company, in a worse position than he would have been in if the regulations had been made to have effect only as from the date on which they were made.
