This Article proceeds in two parts. Part I highlights the contours of the Lago Agrio litigation and delves into a discussion about the key events, the arguments presented by the parties, and the position taken by the courts of Ecuador at different levels. This part continues with a discussion of the Ecuadorean proceedings on appeal and concludes with a description of Chevron's preemptive attempt to block the enforcement of the Lago Agrio judgment in Ecuador, the United States, and elsewhere. Part II describes the plaintiffs' attempts to seek recognition and enforcement of the Lago Agrio judgment in Brazil and Argentina, with special focus on the litigation strategies employed by the parties, their direct impact on the outcome of the Lago Agrio litigation, and the possible effect of the Chevron-Ecuador saga on the current landscape of transnational litigation in the region.
