Lulinha investigation proceedings were formally authorized by Brazil’s Supreme Federal Court (STF) on Thursday, July 30, 2026, as Minister Andre Mendonca approved a Federal Police request to open an inquiry into Fabio Luis Lula da Silva, the eldest son of President Luiz Inacio Lula da Silva.

STF Authorizes Inquiry
The Federal Police (PF) sent its formal request to the STF on Friday, July 24, 2026.
Minister Andre Mendonca reviewed the petition and authorized the investigation six days later, on July 30.
The inquiry will examine whether Fabio Luis Lula da Silva, widely known by the nickname ‘Lulinha’, allegedly acted as an intermediary for private interests seeking access to the presidential palace and the Ministry of Health.
The specific focus is the suspected intermediation of business deals in the medicinal-cannabis market, particularly products containing cannabidiol (CBD).
All allegations at this stage are suspicions presented by the Federal Police and have not been tested in court.
Scope of the Allegations
The Federal Police request cites an alleged partnership between Lulinha, businesswoman Roberta Luchsinger, and lobbyist Antonio Carlos Camilo Antunes.
Antunes is known by the nickname ‘Careca do INSS’, a reference to Brazil’s National Social Security Institute.
The trio allegedly acted on behalf of a company called ‘World Cannabis’, which is linked to Antunes.
Investigators suspect the group sought to influence Ministry of Health programs that authorize the commercialization of medicinal-cannabis products.
The suspected crimes under investigation include influence-peddling, known in Brazilian law as ‘tráfico de influência’, and potential corruption.
No formal charges have been filed against any of the individuals named in the inquiry.

The Lulinha Investigation in Context
Fabio Luis Lula da Silva is the eldest of President Lula’s five children and has previously worked as a technology entrepreneur.
He has largely maintained a low public profile during his father’s third presidential term, which began in January 2023.
Investigations involving relatives of sitting Brazilian presidents are historically sensitive and carry significant political weight.
The opening of an inquiry does not imply wrongdoing or guilt under Brazilian law.
Legal experts emphasize that a Federal Police investigation is a preliminary step to determine whether sufficient evidence exists to bring formal charges.
Lulinha is presumed innocent, and his legal representatives have not yet issued a public statement on the matter.
Political and Electoral Landscape
The authorization comes as Brazil approaches the October 2026 presidential election, in which President Lula is widely expected to seek re-election.
Political analysts note that any investigation touching the presidential family will face intense scrutiny from both allies and opponents.
The STF, Brazil’s highest constitutional court, has played a central role in numerous high-profile corruption investigations over the past decade.
Minister Andre Mendonca, who authorized the inquiry, was appointed to the STF by former President Jair Bolsonaro in 2021.
Mendonca is a conservative jurist and former attorney general who has ruled on several politically sensitive cases.
The investigation will proceed under judicial secrecy, a standard practice in Brazilian criminal inquiries at this stage.
Medicinal-Cannabis Regulation in Brazil
Brazil’s medicinal-cannabis market has grown rapidly in recent years, with the National Health Surveillance Agency (Anvisa) authorizing several CBD-based products.
The Ministry of Health also manages programs that facilitate patient access to medicinal cannabis through the public health system, known as SUS.
Companies seeking to participate in these programs must navigate complex regulatory approvals, creating potential entry points for lobbyists and intermediaries.
The Federal Police’s interest in this sector suggests investigators are examining whether personal connections were allegedly used to fast-track or influence authorizations.
Brazil’s legal framework for medicinal cannabis remains a subject of legislative debate, with Congress considering broader cultivation and distribution laws.
Next Steps in the Inquiry
The Federal Police will now begin collecting documents, conducting interviews, and gathering evidence under the supervision of the STF.
There is no set timeline for the investigation, which could last months or longer depending on its complexity.
If investigators find sufficient evidence, they will forward their findings to the Prosecutor General’s Office, which decides whether to file formal charges.
Only after formal charges are accepted by the STF would Fabio Luis Lula da Silva become a defendant in a criminal case.
Until then, he remains an investigated person with full presumption of innocence guaranteed by Brazil’s 1988 Constitution.
