On the 11th of February 2017, our Association organised a Brexit simulation, where the member states of the European Union were represented by the participants in the institutional framework of the European Council. During the one-day simulation the participants discussed determinative questions focused on the British secession and its consequences. The event gave the opportunity to the delegates to make decisions in four blocks of debate according to the interests of the represented country. As a result of the reconciliation, the most important purpose was the submitting of a decree unanimously approved to the Presidency. At the beginning of the simulation, the delegates expounded their country’s position paper, which included the interests and the targets that enjoy the priority of the Brexit in the policy of the given country, as well as the public perception about the recession. After the opening ceremony, the debates were influenced by the negotiation of the EU-UK delegation and the incoming news that the delegates had to take into consideration during their conference. During the fifteen-minutes informal negotiations, the delegates had the possibility to assign new common directives and to discuss and elaborate these destinations immediately. Thanks to the effective collaboration, the Council has submitted the decree to the Presidency, and a conception has been approved about Great Britain’s exit policy. This decree dictated the policy that the delegated negotiators of the Union will discuss with the United Kingdom and the policy that deal with the additional political, economic and cultural affair of the leaving-party and the Union. During the creation of decrees, the debate-units dealt with many questions like the principle of the four freedoms, institutional issues, foreign and security policy cooperation, legal conditions over and above the United Kingdom’s financial participation in the European Union’s common policy. The simulation provided a great opportunity to gain a more detailed insight into the decision-making mechanism of the European Council. During the dispute and the debate-units, the delegates got a possibility to validate their interests as well as to develop different soft skills mostly in the area of negotiation-techniques. Dr. Lajos Bárdi, the instructor valued the debate-culture, the ability to compromise and convince, the argumentation of the delegates and proposed different techniques for them.
