This story in Law360 reports on arguments before the Washington Supreme Court in a case in which a jury awarded $135 million in punitive damages against Monsanto, based on allegations that chemicals leaked from light fixtures in a school.  We previously reported on the case here. At the core of the dispute is the fact that Washington law does not permit punitive damages, but the trial court allowed the plaintiffs to recover punitive damages by applying a mixture of Washington law and Missouri law.
