The Entidade de Contas e Financiamento Político (ECFP) from Tribunal Constitucional, assigned to CEI-IUL a study with the objective to validate the campaign costs. Comparing those costs with budgets sent to ECFP will allow to eventually point out the discrepancy between budgets and campaign acts taken by the different parties during the Municipal Elections’ campaign of 2017. The project has also a scientific branch that intends to study and evaluate  the type and evolutions of campaign’s acts and means at municipal elections.
