Supreme Court Minister Cristiano Zanin has rejected a request aimed at compelling the Chamber of Deputies to create a Parliamentary Inquiry Commission (CPI) concerning Banco Master. The request was filed by Deputy Rodrigo Rollemberg of the PSB party after he received no response from the Chamber's president, Hugo Motta, regarding the creation of the CPI, which gathered over 200 signatures by February 2. Zanin ruled that the claim did not present sufficient evidence of neglect by Motta in addressing the request.

In his decision, Zanin noted that the elapsed time since the formal request was made was too short to infer any personal resistance from the Chamber's authority. He emphasized that the rejection should not be misconstrued as a hindrance to the Chamber's constitutional right to establish a parliamentary inquiry, even in parallel with existing Supreme Court investigations led by Minister André Mendonça regarding the same issue.

This ruling illustrates a critical moment in Brazilian politics, where calls for transparency and accountability surrounding financial institutions are increasingly vocal. The implications of the ruling extend beyond the immediate decision as it touches upon the balance of powers within Brazil's government and the oversight capabilities of legislative bodies, illustrating ongoing tensions between different branches of governance in dealing with potential corporate malfeasance.
