Where a national regulatory authority concludes that a relevant market does not justify the imposition of regulatory obligations in accordance with the procedure in paragraphs 1 and 2 of this Article, or where the conditions set out in paragraph 4 of this Article are not met, it shall not impose or maintain any specific regulatory obligations in accordance with Article 68. Where there already are sector specific regulatory obligations imposed in accordance with Article 68, it shall withdraw such obligations placed on undertakings in that relevant market.
National regulatory authorities shall ensure that parties affected by such a withdrawal of obligations receive an appropriate notice period, defined by balancing the need to ensure a sustainable transition for the beneficiaries of those obligations and end-users, end-user choice, and that regulation does not continue for longer than necessary. When setting such a notice period, national regulatory authorities may determine specific conditions and notice periods in relation to existing access agreements.
