The drastic weight loss of a lobbyist suspected of selling judicial decisions became the target of internal investigations at the Brasília Federal Penitentiary in a case taken to the minister of the (Supreme Federal Court).
The lobbyist is Andreson Gonçalves de Oliveira, pivot of , who investigates whether there were sales and leaks of decisions at the (Superior Court of Justice).
Andreson was arrested on Zanin’s orders in November 2024. In July of the following year, after losing weight, he was transferred to house arrest, in Primavera do Leste (MT). Shortly before this transfer, images of Andreson were released in which his ribs were visible.
In November 2025, however, on Zanin’s orders, he returned to the Federal Penitentiary. One of the reasons cited by the minister was the suspicion that he had forced himself to lose weight to return home — the defense denies this and states that Andreson has diagnosed illnesses that led to this situation.
The Criminal Police also investigated the suspicion that another prisoner, accused of international trafficking and connection with , had tried to replicate a weight loss and obtain house arrest. The second inmate was Andreson’s fellow custodian at the Federal Penitentiary, located in Complexo da Papuda, in Brasília.
At the time he went to home care, the defense claimed that Andreson had lost 30 kg. He had already undergone bariatric surgery, suffers from health problems and needs a special diet.
The lobbyist’s defense, led by criminalist Eugênio Pacelli, always classified his return to prison in November as “as surprising as it is unfounded” and said he would even sue the Inter-American Court of Human Rights in favor of his client.
The understanding is different from that reached by the Criminal Police in a statement forwarded to Zanin by the (Attorney General’s Office).
Under reservation, there are mentions that the lobbyist discarded part of the meals, supposedly down the toilet. Furthermore, he began to present neurological complaints.
“Environmental recording records carried out in security areas of the Brasília Federal Penitentiary were sent to Zanin, with elements denoting a strategy aimed at improperly obtaining house arrest or transfer to a state prison unit”.
From the demonstration, the minister understood that Andreson “acted in a way to conceal the symptoms and deliberately present a health condition that was more serious than the real one, in order to obtain humanitarian house arrest.”
A report carried out before Andreson returned to prison also showed that he had gained 13 kg in three months and was even overweight. It also said that he showed no problems with accessibility “nor signs of recent use of equipment such as a wheelchair or metal IV pole.”
It also stated that he moved to the upper floor “without difficulties or apparent mobility limitations”.
Afterwards, suspicions were raised about another prisoner: William Barille Agati, suspected of being a PCC “handyman” and accused of international drug trafficking.
The Criminal Police told Zanin that, as Andreson’s “custodial companion”, Agati “in addition to having hired the same lawyer [do lobista]reproduced the pattern of food refusal and drastic weight loss”.
The lawyer mentioned by the police is Luís Henrique Prata, who has worked for Andreson since the beginning of the operation. When contacted, Prata states that he only acted for Agati in a request for habeas corpus and denies having given any advice regarding food to the client. The PGR even requested an investigation into the defense of Andreson and Agati. Zanin, in turn, said there was no evidence and denied the request.
In addition to the issue related to weight, the minister also stated that he had ordered the lobbyist’s return to prison because he had requested to change his electronic ankle bracelet, but failed “to appear at the Electronic Monitoring Center to do so.”
Eugênio Pacelli, Andreson’s lawyer, criticizes the conclusions presented to the minister. He states that both the “IML report and imaging and blood tests confirmed diabetic neuropathy [em Andreson]which has nothing to do with voluntary weight loss”.
According to the lawyer, although these clinical examinations later demonstrated weight and mobility recovery, he continues to have serious health problems.
Prata, the lobbyist’s other lawyer, also refuted the allegations. According to him, the seriousness of Andreson’s case was such that the Mato Grosso prison system admitted it was unable to treat him.
After being transferred to Brasília, neurosurgeon Paulo Saide, appointed by the defense and described as a professional with a 50-year career, carried out examinations under full monitoring at the federal prison.
In contrast to Andreson’s case, the lawyer claims that his other client, Agati, actually tried to deceive doctors. When seen by the same doctor, he recorded in the report that the patient claimed paralysis, but presented “simulating behavior”. The report does not mention the issue of weight loss.
Prata denied having knowledge of the tactics of prisoners who would throw food down the toilet to simulate weight loss, classifying the information as unprecedented. He left Agati’s defense at the time. The report did not locate the drug suspect’s current lawyer.
At the end of January, Zanin ordered that the STJ present a final report on suspicions involving the sale of decisions by the end of March. He also ordered the agency to comment on whether Andreson should be kept in prison.
