(1)The Minister and the Board of Agriculture for Scotland jointly may, after consultation with the advisory committee to be constituted under this section, make regulations for prescribing anything which under this Act is required or authorised to be prescribed, and generally for carrying this Act into operation; and in particular such regulations may provide—
(a)for varying any of the schedules to this Act;
(b)for prescribing the manner in which articles required to be marked under this Act are to be marked and the nature of such marks;
(c)for prescribing the limits of variation for the purposes of this Act;
(d)for prescribing the manner in which samples are to be taken and dealt with in cases where under this Act they are taken in the prescribed manner;
(e)as to the method in which analyses for determining the percentages of particular substances are to be made;
(f)as to the qualifications to be possessed by agricultural analysts and deputy agricultural analysts and as to the form of certificates of analysis given by them;
and where any schedule is varied by regulations so made, this Act shall have effect as if the schedule as so varied were substituted for the schedule contained in this Act.
(2)For the purpose of assisting and advising them with respect to the making of regulations under this Act, the Minister and Board shall, after consultation with such associations as appear to them to represent the interests concerned, jointly appoint an advisory committee.
(3)All regulations made under this section shall be laid before Parliament as soon as may be after they are made, and if either House of Parliament, within the next subsequent twenty-one days on which that House has sat next after the regulations are laid before them, presents an address to His Majesty praying that the regulations or any part of them may be annulled, they shall thenceforth be void, but without prejudice to the validity of anything previously done thereunder or to the making of new regulations.
