The Supreme Court decided today not to intervene in the ongoing battle between Chevron Corp. and Ecuadorean plaintiffs over an $18 billion judgment against the oil giant. Chevron had wanted the justices to review a January ruling by the New York-based 2nd U.S. Circuit Court of Appeals. The court ruled that the oil company must wait before seeking to challenge enforcement of an Ecuadorean judge's $18 billion judgment in favor of thousands of indigenous Ecuadoreans over alleged oil pollution.
