“The Law on Electoral Administration Bodies defines the STAE as an indirect state administration service with technical and administrative autonomy. It is mandated with the implementation of election operations and for maintaining the voter register database.”

“For this electoral cycle, the STAE conducted two updates of its biometric voter register database. In preparation for the presidential election, from 3 October until 23 December 2016, STAE registered a total of 743,150 voters, which represented an increase of slightly more than 100,000 (or 15 per cent) from the 2012 register. A total of 1,463 non-eligible voters under 17 years of age were also registered.”
