Minister Dias Toffoli's decision to step away from the Banco Master case at Brazil's Supreme Federal Court (STF) has been viewed positively by Leonardo Sica, the president of the São Paulo section of the Ordem dos Advogados do Brasil (OAB-SP). Sica argues that this move indicates a maturity in handling complex legal issues, but he also criticizes the court for not possessing the appropriate jurisdiction to oversee such a case. He emphasizes that the STF is not a criminal court and implies that its engagement in such complex matters can lead to inefficiencies in legal outcomes.

Sica further elaborated that OAB-SP will review an inquiry in March regarding the ethical boundaries of relationships between lawyers and judges, highlighted by discussions surrounding a potential scenario where a lawyer might travel on a private jet with an STF minister, which echoes the current controversy involving Toffoli. This move towards evaluating ethical standards within the judiciary aims to enhance the integrity and public trust in Brazil's legal system.

Meanwhile, the conversation around ethical guidelines was reignited following Minister Edson Fachin's identification of Cármen Lúcia as the rapporteur for a proposed code of ethics for the STF. The emphasis on ethical conduct within the judiciary comes at a critical time, reflecting societal demand for accountability and transparency, especially concerning high-profile cases that have the potential to influence public perception of the judiciary's impartiality and efficacy.
