(1) The Regulator shall attach conditions to individual rights of use for radio spectrum in accordance with Regulation 9(1) in such a way as to ensure optimal and the most effective and efficient use of radio spectrum.

(2) The Regulator shall, before the assignment or renewal of individual rights of use, clearly establish any conditions attached to those rights, including the level of use required and the possibility to fulfil that requirement through trading or leasing, in order to ensure the implementation of those conditions. Conditions attached to renewals of right of use for radio spectrum shall not provide undue advantages to existing holders of those rights.

(3) Such conditions attached to individual rights of use shall specify the applicable parameters, including any deadline for exercising the rights of use, the non-fulfilment of which would entitle the Regulator to withdraw the right of use or impose other measures.

(4) The Regulator shall, in a timely and transparent manner, consult and inform interested parties regarding conditions attached to individual rights of use before their imposition. The Regulator shall determine in advance and inform interested parties, in a transparent manner, of the criteria for the assessment of the fulfilment of those conditions.
