SAN JOSÉ, Costa Rica – February 24, 2026 – The Inter-American Court of Human Rights (IA Court) has issued its judgment condemning the State of Brazil for the systemic impunity surrounding the 1994 "Chacina do Tapanã" (Tapanã Massacre).
In its ruling dated November 25, 2025, the Court found Brazil internationally responsible for violating the rights to judicial guarantees, judicial protection, equality before the law, and the right to the truth, following the extrajudicial execution and torture of teenagers Max Cley Mendes, Marciley Roseval Melo Mendes, and youth Luís Fábio Coutinho da Silva by military police in Belém, Pará.
The judgment marks a significant victory for human rights advocacy, strongly reflecting the legal, sociological, and structural arguments presented in an Amicus Curiae brief submitted by the Facts and Norms Institute (FNI).
Prepared by Roberta Cerqueira Reis, Sofia Viegas Duarte, and Felipe Martins Anawate, the brief was officially recognized by the Court and proved instrumental in shaping the Tribunal's intersectional approach to the case.
Recognizing Dehumanization and Structural Racism
A central pillar of the FNI’s Amicus Curiae was the analysis of how the Brazilian justice system and police forces systematically dehumanize young, Black, and poor populations from peripheral neighborhoods. FNI argued that the reflexive labeling of victims as "bandidos" (bandits/criminals) serves to legitimize excessive lethal force and guarantees subsequent impunity.
The IA Court directly adopted this lens in its merits analysis. In a groundbreaking move, the Court explicitly condemned the conduct of the Brazilian Public Prosecutor during the domestic 2018 jury trial. The Court noted that the prosecutor referred to the victims as "thieves" and "murderers," utilizing negative stereotypes rather than objective evidence. Echoing FNI’s arguments, the Court ruled:
"These affirmations are a clear manifestation of this [structural] discrimination and demonstrate that the Prosecutor assumed the culpability of [the victims]... precisely because they were youths who met these characteristics [young, Afro-descendant, poor, favela residents]."
Consequently, the Court found Brazil in violation of the right to equality before the law and non-discrimination (Article 24 of the American Convention)—a direct validation of the FNI's argument that the victims were denied justice based on systemic racism and social criminalization.
Addressing the "Reports of Resisting Arrests"
The FNI brief also urged the Court to examine the pernicious role of "autos de resistência" (resisting arrest reports), a bureaucratic tool historically used by Brazilian police to mask extrajudicial killings and shift the blame onto the deceased.
While the Court noted it lacked temporal jurisdiction to rule directly on the 1994 documents, it validated the sociological reality highlighted by FNI. The Court acknowledged that the use of these reports creates a biased starting point for investigations, presuming police innocence and forcing investigations to focus on the "moral character" of the victim rather than the legality of the lethal force.
Shaping Structural Guarantees of Non-Repetition
The FNI’s Amicus did not merely analyze the past; it proposed forward-looking, structural remedies to prevent future tragedies. The Court’s ordered "Guarantees of Non-Repetition" closely mirror the specific recommendations submitted by Reis, Duarte, and Anawate:
Anti-Racism and Human Rights Training: FNI requested mandatory anti-racism policies and human rights training for state agents. The Court ordered Brazil to incorporate international standards on equality and non-discrimination—with special emphasis on race, poverty, and place of residence—into the continuous training programs for criminal judges and prosecutors in the State of Pará.
Data Collection on Police Violence: FNI advocated for robust, evidence-based diagnostics. The Court ordered Brazil to implement a data collection system on police violence resulting in death, specifically mandating that the data be disaggregated by race, color, poverty status, and place of residence to monitor access to justice for Afro-descendant populations.
Independent Investigations: Aligning with FNI’s request to break the cycle of military police investigating themselves, the Court reiterated the mandatory requirement that investigations into police killings be conducted by an independent body from the very moment the crime is reported.
A Milestone for Intersectional Justice
The Cley Mendes judgment represents a crucial evolution in Inter-American jurisprudence. By recognizing that the victims suffered a "cascade" of violations exacerbated by their intersectional identities—race, age, and poverty—the Court has set a powerful precedent for holding States accountable for systemic, institutionalized racism within their justice systems.
The Facts and Norms Institute commends the Inter-American Court for this ruling. The profound alignment between the Court's findings and the FNI's Amicus Curiae reaffirms the Institute's commitment to producing impactful human rights research that aids international tribunals in dismantling entrenched structures of state violence and impunity in Latin America.
