As the time for a ruling approaches in Chevron's closely watched court battle with plaintiffs' attorney Steven Donziger, another part of the oil company's campaign to fend off a multibillion-dollar pollution judgment in Ecuador is revving back up. Today is the deadline for post-trial briefs in Chevron v. Donziger, a civil-racketeering lawsuit the company filed against the New York activist and lawyer who engineered a $19 billion contamination judgment in Ecuador in Feb 2011. In its counterattack in federal court in New York, Chevron accused Donziger and his clients -- poor residents of the Amazonian rainforest -- of obtaining their verdict by means of fabricated evidence, judicial coercion, and bribery. Meanwhile, on a parallel legal track, Chevron is trying to extinguish its pollution liability by seeking an international-arbitration ruling against the government of Ecuador.
