This report was originally written in the Brazilian Embassy in Uruguay. It analyses the situation of refugees and Brazilian exiles in Uruguay, which fall under three main boxes according to their legal status: 1) political asylum seekers, 2) refugees (political or not), and 3) permanent residents.  Among the political exiles to receive asylum from the president of Uruguay were important figures such as João Goulart, Leonel Brizola, and Jefferson Cardim.

This report recounts the operation of the detention, torture, and imprisonment of the Brazilian exile Jefferson Cardim de Alencar Osario, along with his son, and his nephew, in Buenos Aires on 11th December 1970 and their arrival at Buenos Aires port from Colonia (Uruguay). The operation was coordinated and carried out by military attachés belonging to the Brazilian embassy in Buenos Aires and agents of the Coordinación Federal (Federal Coordination) of the Argentine Federal Police.
