18Variation or revocation of notice to produce or notice to attend

18 Variation or revocation of notice to produce or notice to attend (1) A person on whom a notice to produce or notice to attend in relation to a Royal Commission is served may make a claim to the Royal Commission— (a) that the person has or will have a reasonable excuse for failing to comply with the notice; or (b) in the case of a notice to produce, or a notice to attend under section 17(1)(b) or (d), that a document or other thing specified in the notice is not relevant to the subject matter of the inquiry. (2) Without limiting what may be a reasonable excuse for the purposes of subsection (1)(a), it is a reasonable excuse for a person to fail to comply with a notice by refusing to give information to a Royal Commission if the information— (a) in the case of a natural person, might tend to incriminate the person or make the person liable to a penalty in relation to— (i) proceedings for an offence with which the person has been charged that have not finally been disposed of; or (ii) proceedings for the imposition or recovery of a penalty that have been commenced against the person but not finally disposed of; or (b) is the subject of parliamentary privilege; or (c) is the subject of public interest immunity; or (d) is prohibited from disclosure by a court order; or (e) is prohibited from disclosure by a provision of another enactment that specifically applies to the giving of information or the production of documents or other things to a Royal Commission; or (f) is prohibited from disclosure by a provision of another enactment that is prescribed by the regulations for the purposes of section 34. (3) If the Royal Commission is satisfied that the person's claim is made out, the Royal Commission, by further written notice served on the person, may vary or revoke the notice. (4) A Royal Commission, by further written notice served on a person, may at any time on its own initiative vary or revoke a notice to produce or notice to attend served on the person. (5) A notice varying or revoking a notice to produce or notice to attend must be served in accordance with section 19.
