Fourth Regional Federal Court (Tribunal Regional Federal da 4ª Região or 4RFC)based in Porto Alegre, has jurisdiction over the three states in Brazil’s Southern Region (Rio Grande do Sul, Santa Catarina, and Paraná). 4RFC is composed of 27 lifetime Federal appellate court justices chosen among federal district court judges, members of the Attorney General’s office, and Brazilian Bar Association representatives who are nominated by the Brazilian president under the federal constitution.
4RFC is responsible for trying and judging federal judges (including judges from military and labor courts) in their jurisdictional areas for common crimes and abuses of office. Its jurisdiction extends to members of the Federal Justice Ministry, except in electoral matters. 4RFC is also responsible for criminal review and termination of regional federal judges, writs of mandamus and habeas corpus against an act of the court itself or that of a federal judge, and habeas corpus when the enforcement authority is a federal judge, and there is a conflict of jurisdiction between federal judges subordinated to the court. On appeals, it tries and adjudicates cases decided by federal and state judges exercising federal jurisdiction in their areas.
In recent years, 4RFC had gradually implemented an electronic legal processing system, which it developed in-house, using freeware available in the region for litigation classes. However, to make this system run properly for 70,000 registered users, the court adopted MySQL Enterprise Edition database. Today, the tool supports an average of 3,500 simultaneous users and 25 million stored documents relating to lawsuits, with excellent stability and performance. This enables 4RFC to deliver critical material to the public with security, ease, and speed.
