On Monday, Chevron filed a new motion for summary judgment in its fraud and racketeering case against the lawyers and expert witnesses who helped 47 Ecuadoreans from the Lago Agrio region of the rainforest obtain an $18 billion judgment against the oil company from an Ecuadorean court in 2011…A onetime presiding judge on the Ecuadorean case…submitted a declaration asserting that he acted as the middleman in setting up a $500,000 bribe from plaintiffs' lawyers to the Ecuadorean judge who entered the judgment against Chevron…These latest disclosures are profoundly disheartening, regardless of which side you believe in this case…I'm increasingly skeptical that we'll ever know what happened all those decades ago in Lago Agrio…Yet the longer the case progresses, the more elusive an answer seems to be.
