Utilities Act 2000, section 109(1) and (2)
109 Power to make transitional provision,
(1) The Secretary of State may by regulations
make such transitional and consequential provisions and such savings
as he considers necessary or expedient in preparation for, or
in connection with, or in consequence of -
(a) the coming into force of any provision of
this Act; or
(b) the operation of any enactment repealed or
amended by a provision of this Act during any period when the
repeal or amendment is not wholly in force.
(2) Such regulations may make modifications of
any enactment contained in any Act or subordinate legislation
(including an enactment contained in this Act or in any Act passed
or subordinate legislation made in the same session as this Act).
negative (section 109(3)).
"[Section 109] provides standard transitional
provisions to make regulations to deal with consequential changes
to primary or secondary legislation as a result of the Bill (precedents
can be found in, e.g., section 42 Food Standards Act 1999). For
example, a number of regulations or orders made under the Gas
Act 1986 and the Electricity Act 1989 will need to be amended
to replace references to the Director General of Gas Supply and
to the Director General of Electricity Supply with references
to the Authority. Delegated legislation is thought to be appropriate
in this case since these are matters of detail arising under the
Procedure: It is considered that the negative resolution
procedure is appropriate given the limited and detailed nature
of the power."
Committee Report (17th of 1999-2000):
"There are negative powers in each of the following
109] (power to make transitional provision, etc). In each of these
cases the Committee considers both the proposed delegation, and
the negative resolution procedure, appropriate."
