Abstract
The European Union is run on a sophisticated system based on a hierarchical structure. Relative political powers of member states in the Council of the Euro- pean Union, an important legislative institution in the European Union, are of interest to us. In the first part, we will illustrate some basic concepts of Shapley-Shubic Power Index, Banzhaf Power Index, and the specific voting regulation and the definition of qualified majority in different situations. In the second part, we will use the above-mentioned indices to show the political powers of selected countries in the Council of the European Union under the Treaty of Nice and the Treaty of Lisbon, both of which basically adopt qualified majority voting system. In the third part, we will evaluate the utility of our indices in measuring real power distribution by taking other factors into consideration. Finally, we will conclude on the effect of power shift in the EU from one treaty to the other.
