Name in original language
Galileu
Initiative overview
The Galileu initiative was developed by the Regional Labor Court of the 4th Region (TRT-RS), in Brazil, to address procedural delays and workload pressures resulting from the large volume and complexity of judicial cases. Drafting decisions and conducting legal research require significant time and involve repetitive tasks, which contribute to delays in the delivery of justice. Galileu uses generative artificial intelligence to read case files, organise the issues in dispute, produce structured draft decisions, and provide reliable legal references, contributing to greater efficiency and legal certainty.
The main objective of the initiative is to increase productivity and improve the quality of judicial decisions by reducing bureaucratic steps and allowing judges and staff to focus on more complex analytical work. The tool generates original content from case files, summarises the parties’ arguments, and suggests legal reasoning based on a closed and validated database, reducing the risk of inaccurate outputs. All suggestions remain fully editable, preserving judicial autonomy and the individualised analysis of each case.
The solution was designed with strong attention to information security, data protection, and the mitigation of risks associated with generative AI. Data are anonymised, securely transmitted, and processed within a controlled environment, while the use of validated legal sources reduces the risk of “hallucinations.” Development followed a collaborative approach involving judges and technical teams, with gradual implementation and user training to ensure safe and effective use.
Galileu has been institutionalised as a national tool within the Labor Justice system and continues to evolve to support different stages of judicial work. Adopted by the Superior Council of Labor Justice (CSJT) and made available to all Regional Labor Courts, the system is already in use, in addition to TRT-RS, by several other courts. Its expansion to the second instance now supports appellate judges and their teams in drafting decisions and organising procedural information, and the solution has also been extended to assist in the analysis of review appeals, structuring rulings and indicating relevant content based on prior decisions and case documents. This evolution demonstrates the maturity of the initiative, its adaptability to different stages of judicial proceedings, and its potential to strengthen efficiency, standardisation, and legal certainty, while laying the groundwork for future integration within the digital ecosystem of the Labor Justice system.
