1.Member States and their competent authorities shall ensure that the use of radio spectrum is organised on their territory in a way that no other Member State is prevented from allowing on its territory the use of harmonised radio spectrum in accordance with Union law, especially due to cross-border harmful interference between Member States.
Member States shall take all necessary measures to this effect without prejudice to their obligations under international law and relevant international agreements such as the ITU Radio Regulations and the ITU Radio Regional Agreements.
2.Member States shall cooperate with each other, and, where appropriate, through the RSPG, in the cross-border coordination of the use of radio spectrum in order to:
(a)ensure compliance with paragraph 1;
(b)resolve any problem or dispute in relation to cross-border coordination or cross-border harmful interference between Member States, as well as with third countries, which prevent Member States from using the harmonised radio spectrum in their territory.
3.In order to ensure compliance with paragraph 1, any affected Member State may request the RSPG to use its good offices to address any problem or dispute in relation to cross-border coordination or cross-border harmful interference. Where appropriate, the RSPG may issue an opinion proposing a coordinated solution regarding such a problem or dispute.
4.Where the actions referred to in paragraph 2 or 3 have not resolved the problem or dispute, and at the request of any affected Member State, the Commission may, taking utmost account of any opinion of the RSPG recommending a coordinated solution pursuant to paragraph 3, adopt decisions addressed to the Member States concerned by the unresolved harmful interference issue by means of implementing acts to resolve cross-border harmful interference between two or more Member States which prevent them from using the harmonised radio spectrum in their territory.
Those implementing acts shall be adopted in accordance with the examination procedure referred to in Article 118(4).
5.The Union shall, upon the request of any affected Member State, provide legal, political and technical support to resolve radio spectrum coordination issues with countries neighbouring the Union, including candidate and acceding countries, in such a way that the Member States concerned can observe their obligations under Union law. In the provision of such assistance, the Union shall promote the implementation of Union policies.
