8 Section 13 Participation in the auction An enterprise, organisation or association wishing to participate in the auction shall inform Ficora in advance of its participation and pay a participation fee laid down in section 286. Only one enterprise of a corporate group referred to in Chapter 1(6) of the Accounting Act (1336/1997) is allowed to participate in the auction. No cooperation concerning the auction is allowed between parties participating in the auction. Prohibited collusion is considered to include: 1) agreements concerning the contents of the bids; 2) exchange of information concerning the contents of the bids during the auction process; and 3) any other contact between the applicants with the aim to affect the process and result of the auction. Section 14 Openness of information in the auction process The name and other information of the enterprise, organisation or association provided in the auction registration are not public before the conclusion of the auction process. The winning bids are disclosed after the auction process has been concluded. Other bids made by an enterprise, organisation or association are confidential. During the auction Ficora may issue the total amount in EUR of the bids placed on each round. The bidders are also provided with the information on the number of bids made for the frequencies and the amount of the highest bid in EUR. Other provisions on the openness of information are issued in the Act on the Openness of Government Activities (621/1999). Notwithstanding secrecy provisions, Ficora shall, at request, disclose information referred to in subsections 1 and 2 necessary for supervision and control to the Ministry of Transport and Communications it has obtained while carrying out duties under this Chapter. Section 15 Rejection of auction bids If the effective control in the enterprise, organisation or association changes before the licence is granted so that the enterprise, organisation or association no longer meets the requirements for entering the auction laid down in section 13, Ficora shall reject the bid made by the enterprise, organisation or association. Ficora may decide to reject a bid made by an enterprise, organisation or association, if the enterprise, organisation or association has provided fundamentally incorrect information of matters significant to the auction or if it otherwise violates the provisions of Chapter 3 or Finnish Communications Regulatory Authority regulations and, despite being requested to do so, fails to immediately rectify its actions. The Government may decide to reject a bid made by an enterprise, organisation or association, if it has especially weighty reasons to suspect that granting a licence to the applicant would apparently risk national security.
