In the framework of the Association Agreement between Chile and the European Union (UE) in 2002, which constitutes the juridical framework establishing a political and economic association between both parties that covers a wide range of areas, also includes the social development. In this context we will study in detail the European Ombudsman, which is on the one hand, formally a parliamentary body at a supranational level, designed to strengthen the supervision and control of European Institutions and Administrations; besides, he has developed a specific new concept of maladministration and his faculties extended to the protection of fundamental rights. The powers of the Ombudsman, give him the opportunity to combine the instruments of parliamentary scrutiny and judicial control in an original way. Another important aspect we would like to underline is that under certain circumstances the Chileans citizens could address this institution and at a state level it may be possible to maximize the effort of transferring the experience of this institution to Chile to enhance non-jurisdictional mechanisms to improve the accountability on the activities of the institutions of the State.
