Daniel Vorcaro, the former controlling owner of Banco Master, has asked the Inter-American Commission on Human Rights (IACHR) to take up a complaint against the Brazilian government. His lawyers are seeking to reverse his detention, which began in March 2026, and allege that his human rights have been violated. The commission is an organ of the Organization of American States (OAS) responsible for promoting and protecting human rights in the Americas.
The defense says Brazil’s Supreme Federal Court has not ruled on a request to release Vorcaro that was filed on September 18. His lawyers also argue that his pretrial detention has not been reviewed every 90 days, as Brazilian law requires. They say that, so far, the Office of the Prosecutor General has not filed charges against him.
The complaint also concerns the disclosure of private conversations and personal information taken from Vorcaro’s cellphone, which was seized by the Federal Police. His lawyers contend that publishing private messages unrelated to the matters under investigation violated his privacy. The defense is presenting the alleged disclosure alongside its claims about the pending release request and the review of his detention.
The IACHR accepts petitions from individuals and organizations alleging human rights violations by OAS member states. Its work includes reviewing individual petitions, monitoring human rights conditions in member states and addressing priority thematic areas. The commission has also identified the protection of vulnerable populations and groups that have faced historical discrimination as a priority in advancing human rights across the Americas.
The commission may seek explanations from governments, recommend measures and request urgent action to protect people at risk. It can also refer certain cases to the Inter-American Court of Human Rights. But the IACHR cannot directly order the release of a person in custody. Vorcaro’s request is therefore an appeal to an international human rights body, not a decision that can itself overturn his detention.
The defense says its request for a review of Vorcaro’s detention remains pending at the Supreme Federal Court. The Banco Master case was initially assigned to Justice André Mendonça and is now under the responsibility of the court’s president, Chief Justice Edson Fachin.
