It shall be lawful for the Minister of Agriculture and Fisheries and the Secretary of State for Scotland (in this Act referred to as the " Minister" and "the Secretary of State" respectively), acting jointly, to prohibit by order either absolutely, or except under a licence granted under this Act, the importation into and the keeping within Great Britain of any animal of the species designated Fiber zibethicus or Ondatra zibethica, and commonly known as the musk rat, or musquash.

An order made under this subsection may prohibit absolutely the importation of musk rats notwithstanding that the keeping of them is not prohibited absolutely.

Every order made under the preceding subsection shall, so soon as may be after it is made, be laid before each House of Parliament and if either House of Parliament within the next subsequent twenty-eight days on which that House has sat after any such order has been laid before it, resolves that the order shall be annulled, the order shall thenceforth be void, but without prejudice to the validity of anything previously done thereunder or to the making of a new order.
