presentación de amicus curiae en la acción de amparo interpuesta por Martin Charaja Valdez y otros en el Expediente Nº 01129-2012-PA/TC

This document is an amicus curiae brief submitted by EarthRights International and the Center for International Environmental Law to the Constitutional Court of Peru. It argues that the Peruvian state violated the fundamental rights of the Arboleda indigenous people and other titled peoples in the Tiquillaca district by granting mining concessions without prior consultation, as required by international law and the Peruvian Constitution.

• The Peruvian state, including the Geological Mining and Metallurgical Institute of the Ministry of Energy and Mines, failed to conduct the prior consultation required by Article 6 of ILO Convention 169 and the American Convention on Human Rights before granting mining concessions in the Arboleda indigenous village and other titled villages in the Tiquillaca district.
• The failure to consult indigenous peoples before granting mining concessions creates a void of nullity in those concessions under Article 46 of the Peruvian Constitution. This nullity can only be corrected by reviewing the concessions according to international law requirements.
• Under the doctrine of 'control of conventionality,' the Peruvian Judiciary is obligated to ensure that domestic laws do not undermine the effects of the American Convention on Human Rights. This includes applying the binding jurisprudence of the Inter-American Court of Human Rights (IACtHR) regarding indigenous rights.
• According to IACtHR standards, an adequate consultation must be conducted previously, in good faith with the aim of reaching an agreement, be appropriate and accessible, and be informed. Additionally, the state must ensure that no concession is issued without a prior social and environmental impact study conducted by independent and technically capable entities.
• International law requires the free, prior, and informed consent of indigenous peoples—rather than just consultation—when development or investment plans are large-scale and would have a major impact on their territory, which is typically the case with industrial mining projects.
