Legal institutions in Mato Grosso are addressing technological and administrative shifts within the justice system. The Public Prosecutor's Office of Mato Grosso (MPMT) organized a webinar titled ‘Justice System in the Era of Artificial Intelligence’ to examine the ethical, legal, and practical implications of AI, including data protection and technological efficiency. Concurrently, legal professionals in Cuiabá participated in the IV Inova ADV Experience 2026 congress to discuss how new technologies are reshaping professional practices.

In terms of judicial administration, twenty-eight lawyers have registered to compete for three judge-member positions at the Regional Electoral Court of Mato Grosso (TRE-MT). These vacancies, set to open in May 2027, include two titular positions and one substitute position. Following Superior Electoral Court (TSE) guidelines for gender parity, one titular position is reserved for female candidates. The selection process involves the Mato Grosso Court of Justice (TJ-MT) defining candidate lists for final appointment by the President of the Republic.
