The District Court denied the defendant’s objections to confirmation of a Canadian award. The defendant claimed that the arbitral tribunal had violated due process by not adequately placing him on notice that the legal import of a certain letter would be a dispositive issue, and had erred by excluding the expert evidence presented by the defendant. The Court found that these objections were barred by res judicata, because the same argument had been denied by a Canadian court, before which Nelson had unsuccessfully sought the award’s annulment.
