Humberto Piaguaje, representative of Ecuadorean people affected by environment damage caused by Chevron-Texaco in the Amazon basin region, speaks next to the lawyer Juan Pablo Saenz (R) during a press conference in Quito on November 13, 2013Ecuadoran villagers can seek to enforce in Canada a multi-billion-dollar Ecuadoran judgment against US oil giant Chevron on pollution in the Amazon rainforest, the country’s top court said Friday. Chevron’s Canadian subsidiary dismissed the ruling, calling the Ecuadoran judgment fraudulent and unenforceable. In Canada and in parallel legal fights in the United States and Brazil, the indigenous people of Ecuador’s Lago Agrio region have sought to collect compensation for the mass dumping of oilfield waste between the 1970s and 1990s, after an Ecuadoran court ordered Chevron to pay $9.5 billion in damages.
