An attempt by Ecuadorian villagers to have a Canadian court enforce a $19 billion judgment against…Chevron Corp has been dismissed by the Ontario Superior Court. Justice David Brown ruled…that the Canadian courts have no jurisdiction to enforce the controversial award handed down by an Ecuadorian court against Chevron. The award to the villagers was made in Ecuador for black sludge contamination of a rainforest between 1972 and 1990 by Texaco, which Chevron Corp. bought in 2001…Brown concluded the judgment was levied against Chevron Corp., and not Chevron Canada, therefore the subsidiary's assets do not belong to the U.S. parent company.
