Brazil’s Supreme Court absolves over ten from INSS inquiry, sparking legislative dissent

Decisions by Brazil’s Supreme Federal Court (STF) have released at least ten individuals from testifying before the Joint Parliamentary Commission of Inquiry (CPMI) investigating fraud within the National Institute of Social Security (INSS). This judicial intervention has ignited significant friction with the legislative body, whose leaders contend these rulings impede their investigative efforts into a pervasive scheme of improper discounts applied to retirees’ and pensioners’ benefits.

The core of the dispute centers on the STF’s granting of habeas corpus requests, effectively exempting key figures from mandatory appearances before the commission. These individuals were deemed crucial to unraveling the complex financial mechanisms behind the alleged fraud, raising questions about transparency and accountability in a critical public inquiry.

The ongoing clash underscores a persistent tension between the judiciary and the legislature, with each branch asserting its constitutional prerogatives. The CPMI leadership maintains that the court’s actions represent an overreach into parliamentary duties, potentially jeopardizing the full scope and efficacy of its mandated investigation into widespread financial misconduct.

Key figures bypass inquiry with judicial orders

The most recent high-profile instance of judicial exemption involved Leila Pereira, president of Banco Crefisa. Her scheduled testimony before deputies and senators on the last Wednesday, March 18, 2025, was abruptly canceled after Justice Gilmar Mendes granted a habeas corpus, relieving her of the obligation to appear. This decision followed a trend of similar rulings that have consistently derailed the commission’s meticulously planned calendar.

Earlier in the investigation, in September 2024, Justice André Mendonça also granted habeas corpus to Antônio Carlos Camilo Antunes, widely known as “Careca do INSS,” and entrepreneur Maurício Camisotti, excusing them from the inquiry. This particular ruling marked a significant turning point, escalating the procedural disagreements into a full-blown constitutional confrontation between the CPMI and the highest court in the land.

The expanding list of excused witnesses

The list of individuals who have successfully secured permission from the STF to avoid testifying before the INSS CPMI has steadily grown, encompassing a range of business leaders and public figures. These exemptions have collectively undermined the commission’s ability to gather firsthand accounts and critical information from those directly involved or closely associated with the alleged fraudulent activities. Key names on this list include Maurício Camisotti, an entrepreneur who was expected to testify on September 18, 2025; Thiago Schettini, another entrepreneur, anticipated on November 17, 2025; and Rodrigo Moraes, a partner at ARPAR, whose presence was sought for November 24, 2025.

Further exemptions were granted to Danilo Trento, an entrepreneur expected on November 27, 2025, and Sandro Temer de Oliveira, a representative of various associations, whose testimony was scheduled for December 1, 2025. Daniel Vorcaro, former owner of Banco Master, also secured an exemption, missing his February 23, 2026, hearing. State deputy Edson Cunha de Araújo (February 26, 2026), former Banco Master CEO Augusto Ferreira Lima (March 11, 2026), and Aristides Veras dos Santos, president of Contag (March 16, 2026), complete the list of those who have bypassed the inquiry through STF decisions, alongside Leila Pereira (March 18, 2026).

Judicial-legislative clash escalates

Carlos Viana (Podemos-MG), who presides over the CPMI, has openly criticized the series of STF decisions, labeling them as direct interference in the legislative branch’s constitutional duties. This strong rebuke highlights the deepening rift between the two powers, with Viana consistently asserting that such judicial actions hinder the parliament’s capacity to investigate and hold accountable those involved in the INSS fraud.

Despite being granted an exemption, Antônio Carlos Camilo Antunes, “Careca do INSS,” notably chose to appear before the commission and provided his testimony on September 25, 2024. This voluntary appearance offered a rare instance where a key witness defied a judicial waiver, providing some insight to the inquiring legislators amidst the broader wave of exemptions.

The president’s persistent condemnation underscores the view within the CPMI that the judiciary’s expansive use of habeas corpus in this context effectively creates an unlevel playing field, making it exceedingly difficult to conduct a thorough and impartial investigation. The legislative leaders feel that their mandate to scrutinize public funds and services is being undermined by these recurrent interventions.

Secrecy breaks halted by ministerial rulings

Beyond the challenges with witness summons, the CPMI has also encountered obstacles regarding the annulment of secrecy breaks, crucial tools for financial investigations. Earlier this month, Justice Flávio Dino moved to suspend a request approved by the commission concerning Fábio Luís Lula da Silva, widely known as “Lulinha,” son of President Luiz Inácio Lula da Silva (PT). This decision to block access to financial and telecommunications data further complicated the commission’s efforts to trace potential illicit financial flows and connections relevant to the INSS fraud probe.

CPMI’s mandate extended for crucial investigations

Initially established in August 2024, the CPMI was scheduled to conclude its operations by March 28, 2025. However, in a significant development on Monday, March 23, 2025, Justice André Mendonça of the STF ruled to extend the commission’s functioning. This decision, though a judicial one, was celebrated by the CPMI leadership, marking a moment of alignment between the court and the legislative body’s investigative needs.

Justice Mendonça’s ruling deemed the “deliberate omission” of the Congressional Steering Committee and Presidency in processing the extension request unconstitutional. He mandated a 48-hour deadline for the request’s formal reading, thereby ensuring the continuity of the critical inquiry.

While the decision is a preliminary injunction awaiting full plenary ratification by the Court, it was enthusiastically welcomed by the CPMI’s leadership. Carlos Viana lauded the extension as “a victory for Brazil,” emphasizing that this specific judicial intervention served its intended purpose of upholding constitutional principles when parliamentary procedures faced undue obstruction.

Viana, who has frequently been critical of STF decisions affecting the CPMI, notably praised Mendonça’s order. He asserted, “This is what the STF is for. When the Constitution is not respected, the STF must step in. It is not to interfere in parliamentary work as has happened,” distinguishing this positive ruling from previous ones.

Continued focus on consignments and challenges

President Carlos Viana indicated that the extended 60-day period for the CPMI’s work is sufficient to complete its investigations thoroughly, aiming for a unified report from both government and opposition factions. He specified that the commission intends to primarily pursue its inquiry into fraudulent consigned loans, a key area of alleged misconduct targeting pensioners and retirees. This focused approach seeks to deliver concrete findings within the adjusted timeframe.

Moreover, the commission remains determined to challenge the habeas corpus decisions that have exempted witnesses, signaling an intent to explore legal avenues that could compel previously excused individuals to appear. The CPMI also plans to summon new witnesses who are closely connected to pivotal figures in the alleged fraud scheme. These strategic moves aim to overcome prior judicial impediments and ensure a more comprehensive gathering of evidence and testimony crucial for the investigation’s success.
