Some Considerations About a Uunified System for the Voting Procedres of the European Union

The paper analyses the evolution of the decision making process within the EU and assesses the effectiveness of the European voting procedures in the context of current and potential future enlargement. Based on a simulation model, we discussed some different scenarios of the voting procedures’ results within the EU, both for the Council and the Parliament of the European Union. A special attention was paid to the evolution of the voting model in the interval 2009-2050. The paper evaluated the advantages and disadvantages of the different voting systems. We have emphasis all the positive effects of the Penrose square root rule. Despite the criticism formulated around the Penrose model, it remains the only valid model for an effective voting system in the main EU decision-making bodies.
