Paragraph 5
The Secretary of State may designate a local weights and measures authority for the purposes of the enforcement within its area of price controls in relation to supplies to the general public.
The powers of paragraphs 2 and 3 above are also exercisable by a duly authorised officer of a designated local weights and measures authority, for the purpose of securing compliance with price controls in relation to such supplies.
If a justice of the peace (in Scotland, a justice of the peace or a sheriff) is satisfied, on sworn information in writing submitted on behalf of a designated local weights and measures authority, that—
admission to premises is reasonably required for that purpose; and
the circumstances specified in paragraph 4(2) or, as the case may be (3) above are present,
the justice or sheriff may issue a warrant authorising a duly authorised officer of the authority (naming him) to enter the premises, by force if necessary; and paragraph 4(5) to (9) above also applies in relation to this warrant.
