seek to complete the market analysis within the shortest period of time possible. The market analysis shall be completed by a decision of the director of the Communications Regulatory Authority concerning the results of market analysis. The decision shall indicate the results of every completed stage of the market analysis. 12. The Communications Regulatory Authority, prior to adoption of a decision defining a relevant product or service market, identifying or not identifying undertakings with significant market power on the relevant market or imposing, not imposing or withdrawing all or several obligations on these undertakings referred to in Article 17 of this Law where such a decision would affect trade between European Union Member States, shall, at the end of public consultations period set by the Communications Regulatory Authority pursuant to Article 11(1) of this Law, submit a draft of the aforementioned decision to the European Commission, the Body of European Regulators for Electronic Communications and national regulatory authorities of other European Union Member States. The European Commission, the Body of European Regulators for Electronic Communications and other national regulatory authorities of European Union Member States may submit their opinions within one month. After the European Commission adopts guidelines and/or recommendations establishing other public consultation procedure and time limits than those specified in this Article, the public consultation procedure and time limits applicable pursuant to the European Commission's guidelines and/or recommendations shall apply. 13. Should the draft decision referred to in Article 12 define a relevant market differently than it is defined in the recommendation of the European Commission referred to in paragraph 3 of this Article or identify or not identify undertakings with significant market power on the relevant market and should the European Commission notify the Communications Regulatory Authority about its opinion that such a draft decision would create a barrier to a single market or about its serious doubts as to its compatibility with the European Union law, the Communications Regulatory Authority may not adopt such a draft decision for a further two months. If the European Commission within this time limit notifies the Communications Regulatory Authority not to adopt such draft decision, the Communications Regulatory Authority must within a period of six months change the said draft decision or not adopt it. If the Communications Regulatory Authority, having regard to the European Commission notification, amends its draft decision, they shall, in accordance with Article 11(1) and paragraph 12 of this Article of this Law, submit a revised draft decision to the interested persons and the European Commission. 29
