Influence of Boundary Conditions of Digressively Proportional Division on the Potential Application of Proportional Rules

摘要

The most commonly used principle of division of assets and debts is the principle of proportionality, which derived from Aristotle. The main area of application of that rule is the electoral law. An example of another solution can be found in the Lisbon Treaty, which sets out the rule of digressively proportional representation of EU Member States in the European Parliament. The problem is that there are many acceptable solutions. In this paper an attempt is made to determine the boundary conditions in such a way that the rules used for the proportional divisions would also lead to an unambiguous solution in the case of digressively proportional division.
