CALAS and Community of La Puya v. Ministry of Energy and Mines (El Tambor Mine)

Environmental organizations and community members challenged the approval of the El Tambor (Progreso VII Derivada) mining project, alleging deficiencies in environmental licensing and the failure to conduct adequate public participation and consultation. Guatemalan courts granted amparo relief, ordering the suspension of mining operations and finding that the project had been authorized without compliance with constitutional and statutory environmental and participation requirements. The rulings required the State to remedy the licensing and consultation defects before the project could proceed, effectively halting mining activities.
