undertakings and persons taking part in the consideration of the dispute, receive copies of decisions on dispute settlement adopted by the Communications Regulatory Authority, appeal against decisions by the Communications Regulatory Authority, and exercise other rights granted by this Law and the rules for the settlement of disputes between undertakings by the Communications Regulatory Authority. The applicant shall have the right to waive its application for dispute resolution. The respondent shall have the right to acknowledge the application. The parties may end the consideration of the dispute by amicable agreement. Parties to the dispute and other interested undertakings and persons participating in the consideration of the dispute must exercise their rights in a fair manner. 12. The Communications Regulatory Authority shall consider disputes by written procedure unless it decides, at the request of any party to the dispute or at the request of any other interested undertaking or person or at its own initiative, that the dispute may be better considered in an oral hearing at a sitting. The Communications Regulatory Authority shall inform the parties about the sitting; however, failure to appear by any of the parties shall not prevent the Communications Regulatory Authority from considering the dispute, unless provided for otherwise in the rules for the settlement of disputes between undertakings by the Communications Regulatory Authority. The consideration of disputes at a sitting shall be public, except for the cases where the Communications Regulatory Authority decides to consider the dispute at a closed sitting in order to protect state, official or commercial secrets or protect a person’s right to privacy. 13. The Communications Regulatory Authority shall have the right to refuse to accept evidence, requests and motivations if they could have been submitted earlier. 14. The Communications Regulatory Authority shall issue a decision on the dispute over social relations pertaining to the subject of this Law not later than four months from the date of acceptance of the application, except for the disputes over social relations regulated by Article 381 and social relations regulated by Article 39(8) of this Law to the extent they pertain to the receipt of information from infrastructure managers and to the inspection of the infrastructure at the site of its installation or to the shared use of a building and/or its engineering systems. Such decision shall be issued not later than two months from the date of acceptance of the application. The time-limits set out in this paragraph may be extended by a reasoned decision of the Communications Regulatory Authority, where a longer time-limit is required for examining the dispute in view of exceptional circumstances (large amount of evidence, complicated circumstances of the dispute, etc.). 50
