“33A Authorisation by Commission of certain acts
(1) Where a person does any act, in accordance with an authorisation given under subsection (2) or (3) below, which would otherwise be an offence under subsection (1) or (3A) of section 23 of this Act, he shall not be guilty of an offence under the said section 23.
(2) Notwithstanding anything in any agreement between an occupier of agricultural land or of woodland and the owner thereof, but subject to subsections (7) to (10) below, the Commission may authorise such an occupier or any person nominated in writing by such an occupier to take or kill, and to sell or otherwise dispose of, any deer on any such land or woodland during the period specified in section 23(1) of this Act, where they are satisfied that the taking or killing is necessary to prevent serious damage to crops, pasture, human or animal foodstuffs, or to woodland, and no other means of control which might reasonably be adopted in the circumstances would be adequate.
(3) Subject to subsections (7) to (10) below, the Commission may authorise the owner of any land which deer are on, or any person nominated in writing by him, to use any vehicle to drive deer in order to take or kill them for the purposes of deer management; and, for the purposes of this section—
“deer management” does not include driving deer in the course of any sporting activity, and

and no other means of control which might reasonably be adopted in the circumstances would be adequate.

(8) An authorisation shall—
(a) be in writing; and
(b) specify the duration of its validity.
(9) No authorisation shall be granted under subsection (2) or (3) above unless a relevant code has been published under subsection (11) below, and any such authorisation shall contain a condition that the person concerned shall comply with the relevant provisions of any such code.

to which they shall have regard when exercising their power under subsection (2) or, as the case may be, (3) above.”

(3) Until a code is published under section 33A(11)(b) of the principal Act (which is inserted by subsection (1) above), section 23(3A) of that Act shall have effect as if for the word “any”, in the second place where it occurs, there is substituted the word “unenclosed”.
