The Ecuadorians holding a $9.5 billion environmental judgment against Chevron Corporation got some welcome news on Tuesday, when an Ontario court revived their attempt to collect the mega-award in Canada.

In a 29-page decision, the Court of Appeals for Ontario lifted a stay on an enforcement action brought by the Ecuadorians and their lawyers. Reversing a lower court judge, the appellate panel concluded that Ontario’s courts can—and should, as a matter of fairness—rule on whether the Amazon plaintiffs can seize Chevron assets in Canada.
