Opposition members in Brazil have filed a legal request to the Supreme Federal Court for the immediate establishment of a parliamentary investigation commission concerning Banco Master.
On Monday, September 9, opposition lawmakers in Brazil filed a legal writ with the Supreme Federal Court (STF) demanding the immediate creation of a Mixed Parliamentary Investigation Commission (CPMI) into Banco Master. They argue that the President of the National Congress, Senator Davi Alcolumbre, has been unconstitutionally neglecting his duty by failing to read the request to establish the commission, which was initially submitted on February 3, 2026.
The legal document highlights that despite fulfilling all constitutional requirements, Senator Alcolumbre has repeatedly failed to convene a Congressional session or read the request, thereby obstructing the parliamentary minority's rights. Noteworthy signatories of this document include prominent opposition figures such as Bia Kicis and Kim Kataguiri, who emphasize the importance of accountability in the banking sector through the proposed investigation.
This situation reflects ongoing tensions within Brazilian politics, where calls for greater oversight of financial institutions are being met with resistance from governing elites. The outcome of this legal action may have significant implications for both the accountability of public institutions and the dynamics of parliamentary relations in Brazil, especially as the 2026 elections approach.
