On Tuesday, 16, the Plenary Chamber of the Supreme Electoral Tribunal, chaired by Dr Oscar Hassenteufel, hosted the European Electoral Support Centre (EESC) funded by the European Union for an evaluation and planning session on the joint work carried out during the 2025 electoral cycle and the work ahead. As a result of this meeting, the Plenary Chamber and ECES have developed a joint work agenda for both the second round and the subnational process leading up to 2026, based on joint analyses and the short- and long-term recommendations.

The areas of work include strategic communication, institutional management, disinformation, capacity-building, parity, and plural representation. The meeting also allowed for the presentation of a methodological tool developed by ECES that systematises the preliminary reports, including conclusions and preliminary recommendations, from national and international electoral observation missions. This includes, among others, the EU Election Observation Mission (EOM) in Bolivia 2025 and the two largest Bolivian missions that ECES is supporting: the EOM Observa Bolivia and the Ombudsman EOM, which combined for over 2,300 observers on Election Day. The Bolivian 2025 general polls were the most closely observed ever, and the same number of EOMs and observers is expected for the presidential/vice-presidential runoff scheduled for 19 October.  The TSE was represented by Oscar Hassenteufel, as president of the TSE, and the magistrates Tahuichi Tahuichi, Nancy Gutiérrez, and Nelly Arista, and, for ECES, by Luis Castellar, Katia Uriona, and Rafael Loayza.

The European Union leads international efforts in support of the 2025/26 Bolivian electoral process, including the EU EOM Bolivia 2025 and the ECES-implemented PRO-Elección Bolivia project, both carried out through the Foreign Policy Instrument (FPI), along with other election-related projects supported by the EU Delegation to Bolivia.
