Brazil's Supremo Tribunal Federal (STF) held a solemn session on Monday, March 3, 2026, to open the second judicial semester [1].

The event marks the official resumption of the high court's legal proceedings for the latter half of the year. This transition is critical as the court prepares to rule on high-impact social and legal frameworks that affect millions of Brazilian citizens.

The session began at 2 p.m. Brasília time [1] in the STF plenary in Brasília [2]. President Luiz Inácio Lula da Silva attended the proceedings, signaling the executive branch's presence at the start of the 2026 judicial cycle [2].

According to the court's agenda, the STF will prioritize several key legal disputes during this period. One primary focus is the determination of tax exemptions for people with disabilities [2]. The court is expected to clarify the legal boundaries and eligibility requirements for these fiscal reliefs.

Additionally, the court will address the scope and application of the Lei Maria da Penha [2]. This law is the cornerstone of Brazil's effort to combat domestic and gender-based violence. The justices will examine how the law's reach applies to modern legal challenges and enforcement gaps.

The judicial docket also includes the Lei da Dosimetria [2]. This legislation governs the calculation of sentences and the proportionality of penalties in the Brazilian criminal justice system. The court's interpretation of this law will influence how judges determine prison terms across the country.

These proceedings are part of the broader 2026 judicial year [2], which seeks to balance administrative efficiency with the resolution of longstanding constitutional questions. The presence of the president underscores the intersection of judicial rulings and executive policy implementation.

The opening of the second semester focuses the STF on critical human rights and criminal justice issues. By addressing tax exemptions for the disabled and the efficacy of the Lei Maria da Penha, the court is tackling systemic vulnerabilities. Meanwhile, the review of the Lei da Dosimetria suggests a move toward standardizing sentencing, which could either reduce judicial discretion or create new precedents for the national penal system.
