The number of representatives of each sector is distributed according to the rules stated in Art 2, which establishes that there will be one representative for each 83.000 voters included in the electoral register of each sector. According to Article 5 of Decree 2878, no elector can be registered in more than one sector’s register to avoid duplicity of voting. Art 6 states that candidates must be put forward by the sectors with the support of 3% of the register to which they belong. Finally, Art 4 establishes that the constituency for the election of representatives of the Communes is the region and the electoral system is majoritarian. In the case of the other sectors, the constituency is national and the electoral formula is also majoritarian. As a result of these rules, electors are divided by categories; they vote by categories, and are elected only by citizens registered in their category.
