Luiz Fux

Luiz Fux was born on April 26, 1953, in Rio de Janeiro, Brazil, into a family shaped by one of the twentieth century's most harrowing chapters. His parents were Romanian Jewish immigrants who fled German persecution during World War II, arriving in Brazil as refugees in search of safety and a new life. That legacy of survival under extraordinary circumstances formed the bedrock of Fux's upbringing, instilling values of resilience and discipline that would later manifest in both his judicial philosophy and his lifelong dedication to sport.

Raised in the city where he would eventually reach the pinnacle of Brazil's legal system, Fux forged his personal and professional identity against the vibrant backdrop of Rio de Janeiro — the same city that would serve as the setting for his decades-long practice of Brazilian Jiu-Jitsu.

Building a Legal Foundation

Fux earned his law degree from Rio de Janeiro State University (UERJ), launching a career that would span several decades and reach the highest levels of Brazil's judiciary. His early professional years demonstrated considerable range: he worked as an attorney for Shell, served as a prosecutor, and accumulated experience as a judge before ascending to appellate work.

Ascending the Judicial Ladder

In 1997, Fux earned appointment as an appeals court justice to the Court of Justice of Rio de Janeiro, marking his entry into Brazil's senior judiciary. Four years later, in 2001, President Fernando Henrique Cardoso elevated him to the Superior Court of Justice (STJ), one of Brazil's two apex courts. A decade after that, in 2011, President Dilma Rousseff appointed him to the Supreme Federal Court (STF) — the Supremo Tribunal Federal — placing him among the eleven justices who serve as the final arbiters of Brazil's constitutional order.

Independence on the Bench

On the bench, Fux favors in-person deliberations for complex or consequential matters, reserving virtual sessions for routine proceedings. His judicial independence has surfaced in several high-profile cases. In the sentencing debates surrounding the January 8, 2023 incidents — during which fellow Justice Alexandre de Moraes proposed a fourteen-year sentence for defendant Débora dos Santos — Fux advocated for a penalty of one year and six months, reflecting a distinctly measured stance. In the proceedings involving former President Jair Bolsonaro, as of September 2025, Fux stood as the sole justice on the court to oppose precautionary measures against the former president, including electronic monitoring, further cementing his reputation for independent judicial reasoning.

A Commitment That Spans Generations

Fux began practicing Brazilian Jiu-Jitsu at approximately age 26 — an early commitment that laid the foundation for a martial arts journey spanning more than four decades. Sustaining that dedication alongside one of Brazil's most demanding judicial careers distinguishes him in both the legal and BJJ communities.

The Coral Belt: A Lifetime of Mastery

As of September 2025, at age 72, Fux holds a 7th degree coral belt — the red-and-black designation that marks this advanced tier of mastery within the BJJ ranking system. Reaching the coral belt demands not only technical excellence but an extraordinary investment of time and sustained engagement with the art. Major BJJ governing bodies reserve this recognition for practitioners who have dedicated the greater part of their lives to the discipline, and Fux's achievement reflects precisely that kind of lifelong commitment.

The Philosophy of Restful Effort

In a late August 2025 interview, Fux articulated his relationship with the sport in direct terms: "I've always practiced sports throughout my life, my hobby is jiu-jitsu, so I rest by spending energy." That formulation — rest through expenditure — captures something essential about how serious BJJ practitioners experience the art. It speaks to the mental and physical reset that training provides him amid the pressures of Supreme Court service. His continued presence on the mats well into his seventies stands as a compelling demonstration of Brazilian Jiu-Jitsu's well-documented capacity to serve as a meaningful physical practice across an entire lifetime.

The Mat as a Reset

For Fux, Brazilian Jiu-Jitsu is not a peripheral interest but a central pillar of daily life and mental recovery. He identifies the sport as his primary means of decompressing from the considerable demands of serving on the STF, a court whose docket regularly features cases of national constitutional significance. The physical intensity of BJJ training provides an outlet that no sedentary leisure activity could replicate — consistent with the ethos that serious grappling demands full presence and channels stress into structured physical effort.

A Combat Sports Mind Beyond the Dojo

Beyond his own training, Fux engages with combat sports as an attentive and technically literate fan, following UFC events with the enthusiasm of someone who understands the deeper mechanics of what he is watching. His relationship with the sport extends into daily lifestyle choices as well: between court sessions, he reaches for powdered guaraná rather than coffee or tea, a preference that reflects both Brazilian athletic culture and a mindful approach to energy management and performance.

A Symbol of Jiu-Jitsu's Enduring Reach

At 72, Fux represents a meaningful intersection of elite institutional authority and serious martial arts commitment. Within Brazil's BJJ community, he stands as a notable example of the sport's reach far beyond the competitive arena — into the lives of practitioners for whom the mat is, above all, a place of clarity, discipline, and enduring purpose.
