Official Information 11 (3) Any charge fixed shall be reasonable and regard may be had to the cost of the labour and materials involved in making the information available to, and to any costs incurred pursuant to, a request of the applicant to make the information available urgently. (4) The Ministry or Minister of the Crown or organisation may require that the whole or part of any charge be paid in advance. (5) Where a request in accordance with section 11 of this Act is made or transferred to a Ministry, the decision on that request shall be made by the permanent head of that Ministry or an officer or employee of that Ministry authorized by that permanent head unless that request is transferred in accordance with section 13 of this Act to another Ministry or to a Minister of the Crown or to an organisation. (6) Nothing in subsection (5) of this section prevents the permanent head of a Ministry or any officer or employee of a Ministry from consulting a Minister of the Crown or any other person in relation to the decision that the permanent head or officer or employee proposes to make on any request made to the Ministry in accordance with section 11 of this Act or transferred to the Ministry in accordance with section 13 of this Act. 15. Extension of time limits – (1) Where a request in accordance with section 11 of this Act is made or transferred to a Ministry or Minister of the Crown or organisation, the permanent head or that Minister of the Crown or that organisation may extend the time limit set out in section 13 or section 14(1) of this Act in respect of the requests if (a) the request is for a large quantity of official information or necessitates a search through a large quantity of information and meeting the original time limit would unreasonably interfere with the operations of the Ministry or the Minister of the Crown or the organisation; or (b) consultations necessary to make a decision on the request are such that a proper response to the request cannot reasonably be made within the original time limit. (2) Any extension under subsection (1) of this section shall be for a reasonable period of time having regard to the circumstances. (3) The extension shall be effected by giving or posting notice of the extension to the person who made the request within 20 working days after the day on which the request is received.
