(1)This section applies where, by way of civil proceedings, a person (“A”) seeks the disclosure of information by another person (“B”) on the grounds that—
(a)wrongdoing by another person (“C”) has, or may have, occurred,
(b)B was involved with the carrying out of the wrongdoing (whether innocently or not), and
(c)the disclosure is reasonably necessary to enable redress to be obtained or a defence to be relied on in connection with the wrongdoing.
(2)A court may not, in exercise of its residual disclosure jurisdiction, order the disclosure of information sought (whether that disclosure would be to A or to another person) if the information is sensitive information.
(3)“Sensitive information” means information—
(a)held by an intelligence service,
(b)obtained from, or held on behalf of, an intelligence service,

(e)specified or described in a certificate issued by the Secretary of State, in relation to the proceedings, as information which B should not be ordered to disclose.
(4)The Secretary of State may issue a certificate under subsection (3)(e) only if the Secretary of State considers that it would be contrary to the public interest for B to disclose—
(a)the information,
(b)whether the information exists, or
(c)whether B has the information.
(5)For the purposes of subsection (4) a disclosure is contrary to the public interest if it would cause damage—
(a)to the interests of national security, or

(b)does not restrict any other right or privilege that the Secretary of State can claim in order to resist an application for the disclosure of information.
(1)Where the Secretary of State has issued a certificate under section 17(3)(e) in relation to proceedings, any party to the proceedings may apply to the relevant court to set aside the decision on the ground in subsection (2).
