1 1. Before instituting the procedure provided by Section 27, consumers and competitors, either directly or through their associations or organisations, may agree in advance with the trader on the party having responsibility or the body charged with overseeing the code of conduct for a particular sector, on an agreed settlement of the dispute in order to prohibit or put an end to the unfair commercial practice. 2. In all instances, appeals filed pursuant to the previous section, whatever the outcome of the procedure, shall not affect the right of consumers to apply to the Authority pursuant to section 27 or to the appropriate court. 3. Once the procedure before a self-regulatory body has begun, the parties may agree not to apply to the Authority until the final ruling is issued, or they may request the proceeding before the Authority to be suspended in the event that it has also been initiated by another party having a legitimate interest while awaiting the ruling of the self-regulatory body. After examining all the circumstances the Authority may decide to suspend the proceeding for a period of not more than 30 days.
