The body undertaking public duties controlling the data is entitled to charge a fee for making the copies – which fee shall be aligned to costs arising in connection with copying – of which the applicant must be notified before the request is processed. (4) Should the document or document section of which a copy has been requested be large, copying requests shall be fulfilled within a period of 15 days after the payment of the fee charged. The applicant must be notified of the large size of the document or document section of which a copy was requested, the fee charged, as well as options in which case copying is not needed to satisfy data requirements within a period of eight days following the receipt of the request. (5) The relevant legislation regulates cost items and the highest value of these taken into account when setting fee rates, as well as criteria to be applied to determine the large volume of the document of which a copy was requested. Section 30 (1) Should the document containing data of public interest also contain data that cannot be disclosed to the individual requesting the document, such data which cannot be disclosed must be made unrecognisable in the copy. (2) Data requests must be satisfied in a clear manner and in a mode and through the use of the technical instrument specified by the applicant, should the body controlling the data of public interest be easily able to do this.

Requests for data cannot be rejected by claiming that they cannot be properly satisfied. (3) The applicant must be notified of the rejection, the reasons for the rejection, as well as information on legal redress options the individual is entitled to pursuant to the present Act in writing, or electronically should the request have been submitted via email, within a period of eight days.

(6) The body undertaking public duties shall compile regulations setting out the rules of procedure for fulfilling requests aimed at accessing data of public interest. Section 31 (1) The applicant is entitled to turn to the courts should the deadline period open for the rejection or fulfilment of the request for access to data of public interest, or the deadline extended by the controller in accordance with Section 29 (2) expire and become inconclusive, and in addition is entitled to review the fee charged for making a copy, should this fee not yet have been paid. (2) The controller is required to prove the legal grounds of rejection and its underlying reasons and the substantiation of the sum of the fee charged for making a copy. (3) Litigation must be launched against the body undertaking public duties within a period of 30 days following the announcement of the rejection of the request, the expiry of the deadline which was inconclusive and the expiry of the deadline set for paying the fee charged.
