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

The document argues that the Peruvian state violated international human rights law by granting mining concessions in the Tiquillaca district without prior consultation with the Arboleda and other indigenous peoples. It asserts that under the American Convention on Human Rights and ILO Convention 169, such consultations must occur during the earliest planning stages and, for large-scale projects, require free, prior, and informed consent. The authors contend that the failure to consult renders the concessions null and void, requiring the judiciary to review them to ensure the survival and territorial rights of the affected communities.

• 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 ILO Convention 169 and the American Convention on Human Rights before granting mining concessions in the Arboleda indigenous town and other titled towns in the Tiquillaca district.
• The obligation to conduct prior consultation is binding in Peru because it is established in international human rights treaties that have constitutional rank under the Political Constitution of Peru and the doctrine of 'control of conventionality'.
• According to the Inter-American Court of Human Rights (IACHR), 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, no concession should be issued without a prior social and environmental impact study by independent and technically capable entities.
• International law requires the free, prior, and informed consent of indigenous peoples when development or investment plans are large-scale and would have a major impact on their territory, as is typically the case with industrial mining and other extractive projects.
• The failure to conduct prior consultation as required by international law creates a 'vicio de nulidad' (defect of nullity) in the mining concessions, which can only be remedied by reviewing the concessions and implementing measures to ensure adequate consultation.
