(e) any information that the applicant considers that might help identify the information required. 5. If the information request does not specify the format in which the information is requested, it is given in the most efficient and lowest cost for the public authority. Article 12 Clarification and handling of the information request 1. When the public authority, who has received the information request, is unclear about the content and the nature of the request, it contacts the applicant immediately, but no later than 48 hours from the date of the received request, to ask for necessary explanations. In all cases, the public authority shall assist the applicant in clarifying the request. 2. If after reviewing the request, the public authority finds that it does not have the requested information, it sends the request, no later than 10 consecutive days from the date of receiving the request, to the competent authority, and informs the applicant. The sole reason for justifying the forwarding of the request to another authority is the lack of required information. 3. The public authority, to whom the information request was addressed to, notifies the applicant that his request is forwarded to another authority, and informs him of the contacts of the authority where the request is sent to. Article 13 Cost of service 1. Public administration services are free of charge. Disclosure of information can be made against a fee, previously arrived at and made public by the public authority on its website and in premises where members of the public are received. The fee is the cost for the reproduction of the information request and, where appropriate, the cost of delivery. Information requested electronically is free of charge. 2. The cost of reproduction can not be higher than the actual cost of the material on the information reproduced. The cost of delivery can not be higher than the average cost of the same service in the market. 3. The Commissioner for Freedom of Information and Protection of Personal Data examines periodically, in collaboration with the Ministry of Finance, public charges published by public authorities and, where appropriate, orders their amendment.
