41.—(1) If the Authority gives a person (“NP”) a warning notice or a decision notice under these Regulations, it must—
(a)allow NP access to the material on which it relied in taking the decision which gave rise to the obligation to give the notice;
(b)allow NP access to any secondary material which, in the opinion of the Authority, might undermine that decision.
(2) The Authority does not have to allow NP access to material under paragraph (1) if the material is a protected item (as defined in regulation 52(2)) or it—
(a)relates to a case involving a person other than NP; and
(b)was taken into account by the Authority in NP's case only for the purposes of comparison with other cases.
(3) The Authority may refuse NP access to particular material which it would otherwise have to allow NP access to if, in its opinion, allowing NP access to the material—
(a)would not be in the public interest; or
(b)would not be fair, having regard to—
(i)the likely significance of the material to NP, in relation to the matter in respect of which NP has been given a warning notice or decision notice; and
(ii)the potential prejudice to the commercial interests of a person other than NP which would be caused by the material's disclosure.
(4) If the Authority does not allow NP access to material because it is a protected item, it must give NP written notice of—
(a)the existence of the protected item; and
(b)the Authority's decision not to allow NP access to it.
(5) If the Authority refuses under paragraph (3) to allow NP access to material, it must give NP written notice of—
(a)the refusal; and
(b)the reasons for it.
(6) “Secondary material” means material, other than material falling within paragraph (1)(a), which—
(a)was considered by the Authority in reaching the decision mentioned in that paragraph; or
(b)was obtained by the Authority in connection with the matter to which the warning notice or decision notice relates but which was not considered by it in reaching that decision.
