A group of Ecuadorian Indians can seek enforcement of a $9.5bn (£5.8bn) judgement against US petrol giant Chevron in the Canadian courts, an Ontario appeals court has ruled.
Ecuadorian courts awarded the damages in 2011 and 2013 after the villagers sued over 18 years of pollution of the Amazon jungle in the Lago Agrio region.
Chevron has refused to pay, arguing the judgement was obtained through bribery. Chevron is expected to appeal against the ruling to the Supreme Court.
The oil firm has also challenged the judgment under an international trade agreement between the US and Ecuador.
Tuesday's decision by the Ontario appeals court is the latest turn in the two-decade old case between Texaco, which has since been bought by Chevron, and the Lago Agrio villagers.
The unanimous decision by the three-judge panel overturns the ruling of an Ontario superior court justice, who found in May that Chevron had no assets in Canada and the plaintiffs could not gain access to the assets of Chevron's Canadian subsidiary.
