In the opinion of the Venice Commission, the centralisation of the administration of elections at all levels could have a negative impact on the transparency and credibility of the electoral processes on the level of the 32 constituencies, since Mexico is a federal state. It would also entail an onerous transformation that would go against international trends on selfgovernment and could be in conflict with some of the basic principles of current Mexican federalism. The Code of Good practice in electoral matters recommends that “independent, impartial electoral commissions must be set up at all levels, from the national level to polling station level” (II.3.1.b). Since there is a high risk that the new INEC will be formed on a partisan basis, the trust in lower-level electoral bodies to be created on an ad hoc basis for each election on state and local levels could be seriously compromised (notably, taking into account the size of the country, an important number of minorities and its federal structure).
