The Inter-American Court of Human Rights concluded a landmark two-day hearing in Montevideo on Friday, examining allegations that Peru has failed to protect Indigenous peoples living in voluntary isolation in the Amazon from logging and other incursions into their territory.
This marks the first time the regional tribunal has adjudicated a case specifically concerning isolated Indigenous groups in Peru. The proceedings focus on the Mashco Piro, Yora, and Amahuaca peoples, who inhabit remote regions of the Peruvian Amazon. Indigenous organizations argue that logging concessions and expanding frontier activities have driven outsiders deeper into forests these groups rely on, heightening the risk of violent conflict and exposing the isolated populations to pathogens against which they possess little immunity.
“Many of our brothers and sisters have already disappeared, and we don’t want the Mashco Piro to suffer the same fate,” Maglin Alvarado Vargas, a leader of the Yine people from the Native Community of Monte Salvado, testified before the court. “It is in your hands whether they can survive.”
Peru maintains that it has enacted laws, established monitoring protocols, and implemented protective measures for isolated communities. The government did not immediately respond to a request for comment regarding the hearing. However, Julio Cusurichi of the Native Federation of the Madre de Dios River and Tributaries (FENAMAD) contended that these safeguards exist largely on paper. “The government is not taking action to safeguard the rights of these peoples,” Cusurichi stated, warning that continued territorial incursions threaten their very survival.
The dispute spans decades. FENAMAD has sounded alarms over logging in Mashco Piro territory since the 1990s and secured emergency protective measures from the Inter-American Commission on Human Rights in 2007. A formal petition followed in 2011. In 2022, the Commission found Peru responsible for violating the rights of the Mashco Piro, Yora, and Amahuaca. The case advanced to the Court in 2024 after the Commission determined Peru had not complied with its recommendations.
Teresa Mayo of Survival International, which supports the petitioners, described the hearing as historic. She emphasized that the coalition seeks a ruling holding Peru accountable and mandating robust protection of the Mashco Piro’s territory and their right to remain uncontacted. “This is a historic hearing,” Mayo said, adding that the objective is to guarantee the Mashco Piro “can remain uncontacted, with their land fully protected.”
Central to the dispute is the extent of territory allocated to isolated peoples and whether extractive activities can be permitted within those boundaries. Maritza Quispe, an attorney with Peru’s Legal Defense Institute representing the Indigenous side, noted the case could set a critical precedent regarding the ancestral land rights of isolated populations and the legality of state-authorized extraction in their domains.
While Peruvian law generally prohibits outside activity in reserves designated for isolated groups, Quispe highlighted an exception allowing resource exploitation when authorities declare a public necessity. One lawyer for the Indigenous groups argued that Peru had “flagrantly violated” core principles protecting isolated peoples, including the imperatives to avoid contact and keep their territories free from external activity.
Indigenous organizations estimate the Mashco Piro population exceeds 750, spanning southeastern Peru and parts of Brazil. Encounters with outsiders have turned deadly: in 2024, two loggers were killed in bow-and-arrow attacks after entering Mashco Piro territory, and subsequent sightings have placed group members near active logging zones. Contact also poses existential health risks; isolated peoples lack immunity to common illnesses, meaning even minor infections introduced by outsiders could prove fatal.
The parties have until October 26 to submit final written arguments. The Court will then deliberate and issue a binding judgment, though no date for the ruling has been announced.
