Dirección de Observaciones Judiciales (Directorate of Judicial Surveillance, DOJ) is an Argentine intelligence service responsible for intercepting communications as required by judicial officers.
The DOJ is located in a tall, nondescript building on Ave. de los Incas 3834, in Buenos Aires.
The building has an internal surface of 27,000 square feet (2,500 m2) and an estimated monetary value of US$ 1,577,443.
Before moving into its own building it operated out of Telecom Argentina´s Belgrano facility.
During the past few years, there have been allegations of budget mishandlings and phone interventions without a judicial request and authorization; and about SIDE's counterintelligence service also having the capability to intercept communications.
