By the end of 2008, twelve member states of the Council of Europe had adopted legal quotas for national elections. Greece is using them only for local and regional elections. However, these quotas differ considerably both in the required minimum percentages of female candidates on the lists as well as in the possible ranking-order provisions for the lists. Provisions on legal sanctions for non-compliance differ, too. Still more common are voluntary quotas: In the majority of Council of Europe member states at least one parliamentary party has adopted voluntary party quotas.
