Article 18 Amendment of rights and obligations

Member States shall ensure that the rights, conditions and procedures concerning general authorisations and rights of use for radio spectrum or for numbering resources or rights to install facilities may be amended only in objectively justified cases and in a proportionate manner, taking into consideration, where appropriate, the specific conditions applicable to transferable rights of use for radio spectrum or for numbering resources.

Except where proposed amendments are minor and have been agreed with the holder of the rights or of the general authorisation, notice shall be given in an appropriate manner of the intention to make such amendments. Interested parties, including users and consumers, shall be allowed a sufficient period of time to express their views on the proposed amendments. That period shall be no less than four weeks except in exceptional circumstances.

Amendments shall be published, together with the reasons therefor.
