This policy brief was prepared by the European Platform for Democratic Elections (EPDE) to evaluate the increasing impact of politically biased election observation and to contribute to the identification of countermeasures. The Paper was developed ahead of the experts’ Round table “Improving the Accountability of Parliamentarians in Election Observation” hosted by the European Parliament’s Democracy and Election Group (DEG) and the EPDE on March 7th 2017 in the European Parliament in Brussels.
