Article 64 of the Constitution now provides that 140 members of the Assembly are elected “on a proportional system with multi-names electoral zones”. Article 64 also provides that these zones correspond to the administrative divisions “of one of the levels of the administrative-territorial organisation”. The rules for implementation of the electoral system, including the level of administrative-territorial organisation that is to be used for electoral zones and number of mandates to be elected in each electoral zone, are to be determined by the Electoral Code.
