Tribunal de Justiça do Estado do Rio Grande do Sul

The Tribunal de Justiça do Estado do Rio Grande do Sul (TJRS) is the highest judicial authority within the state of Rio Grande do Sul, Brazil, responsible for administering justice across civil, criminal, family, labor, tax and other legal matters. It oversees the lower courts of the state, ensuring uniform application of state and federal laws and providing appellate review of decisions rendered at the municipal and district levels. A core component of its service delivery is the Eproc electronic process system, which enables the digital filing, tracking and management of judicial documents for judges, lawyers, prosecutors and the public. Through Eproc, the tribunal facilitates remote access to case information, streamlines procedural workflows and supports transparency in the judicial process. The institution also issues official notices, regulates internal procedures and coordinates with other branches of government on matters of legal administration. Its daily operations serve a broad constituency that includes citizens seeking redress, legal practitioners representing parties, public defenders and prosecutors, and various governmental agencies.

Distinguishing attributes of the TJRS include its exclusive jurisdictional authority over the state’s territory, positioning it as a key regulator of the judicial sector within Rio Grande do Sul. The tribunal’s experience with the Eproc platform highlights a notable competency in deploying and maintaining large‑scale information technology solutions to support judicial functions, even as it has faced significant cybersecurity challenges. Public records show that the TJRS has endured multiple cyber incidents, including a 2021 REvil ransomware attack that encrypted employee files and disrupted network access, and a 2025 attempt that temporarily restricted external access to Eproc, prompting the issuance of unavailability notices and the activation of backup URLs. These events underscore the organization’s role as a critical infrastructure provider that must balance technological advancement with robust security measures. Structurally, the TJRS is a public institution integral to the Brazilian judiciary, operating under the authority of the state government while maintaining judicial independence as prescribed by the national constitution.
