The Jagiellonian compromise is an electoral system for two-tier voting bodies originally proposed in 2004 [1] for the Council of the European Union as a way of achieving "one person, one vote" within the union. The compromise was analysed by various authors [2] and received attention in the popular press. [3] The system is based on the square root law of Penrose, which implies that a priori voting power defined by the Penrose–Banzhaf index of a member of a voting body is inversely proportional to the square root of its size. Hence the number of votes obtained by a representative of a state with population is proportional to . Jagiellonian Compromise is based on a single criterion only. Decision of the Council of the union of member states is taken if the sum of the weights of states voting in favour of a given proposal exceeds the qualified majority quota equal to
For a generic distribution of population among states of the union, the optimal threshold decreases with as . [4]
