Unchecked Power: The Rising Dominance of Brazil’s Supreme Court

By · · 2 min read

In Brazil, the evolving interactions between the Supreme Court and National Congress reflect a narrative of increasing judicial influence and legislative responses.

The dynamics trace back to a significant uptick in the Court’s decisions affecting congressional tenures. Between 1988 and 2004, just 36 such decisions occurred

However, from 2005 onward, this number dramatically increased to approximately 636, as reported by the Estadão outlet.

Marked by controversial and unconventional rulings, this 1600% increase strained the two branches significantly.

The escalation has been well-documented by researchers at the University of São Paulo’s Group on Judiciary and Democracy.

They note that the Court’s expanded political role has triggered legislative efforts to limit its powers.

For instance, in 2023, measures to curb single-judge rulings were approved, signaling Congress’s intent to redefine judicial boundaries.

The Court’s decisions span several domains: criminal, electoral, and parliamentary.

In criminal cases, actions like search and seizure or lifting secrecy on bank and phone records are common.

Electoral decisions often pertain to crimes, while parliamentary issues usually stem from congressional disputes.

The Court’s heightened role became particularly visible following the Mensalão scandal, signaling a time of more challenged legislative mandates.

From 2005 to 2014, decisions totaled 240, with numbers climbing during the Operation Car Wash period (2015-2018).

However, under Jair Bolsonaro’s presidency (up to 2022), a noticeable decline in such decisions occurred, paralleling a shift in the political and judicial landscapes.

The Court’s individual rulings, often seen as discretionary and lacking in procedural clarity, have fueled perceptions of judicial overreach and partisanship.

These issues, alongside the rise of non-standard judicial measures, have further tarnished the Court’s public image and strained its relationship with Congress.

The backlash from Congress has been pronounced, with numerous proposals aimed at diminishing the Supreme Court’s control over parliamentary mandates.

These proposals not only limit single-judge decisions but also include setting fixed terms for justices and increasing impeachment motions against them.

This unfolding narrative of judicial-legislative interaction sheds light on the broader context of judicial balance in a democratic system.

It highlights the debate on balancing the powers of key Brazilian institutions to ensure governance, judicial independence, and democratic stability.
