This article presents an analysis of the impact of Information Technology (IT) investments in the efficiency of the Brazilian Judiciary System. In order to conduct this investigation, it was adopted the case study method to deal with the complexity of the aforementioned phenomenon. The organizational structure and the informatization trajectory of the Brazilian Judiciary System, the legal framework for electronic lawsuits, as well as the role of the National Council of Justice (NCJ) on the automation of the Brazilian Judiciary System form the basis for understanding the context. A quantitative analysis of the correlation between IT investment and the efficiency of the courts shows a potential positive influence of IT on reducing the duration and cost of lawsuits, thereby increasing the operational and financial efficiencies of the Brazilian Judiciary System.
