This database was created within the framework of the joint programme between the Venice Commission and the European Commission "Democracy through free and fair elections". The Venice Commission and the Mexican Electoral Tribunal of the Federal Judiciary (TEPJF) signed an agreement in October 2013 and since then the VOTA database is being managed jointly by the Secretariat of the Venice Commission and by the Electoral Tribunal. The Venice Commission would like to express its gratitude to the Electoral Tribunal of Mexico for its work in producing and updating the data included in this database.
