Whether Colorado could deny full faith and credit to the Wyoming judgment because the Wyoming court’s findings were allegedly inconsistent with its decree.
Holding
No. If Wyoming had jurisdiction, Colorado could not treat the judgment as void merely because it believed the judgment rested on inconsistent reasoning or legal error.
Reasoning
A state asked to enforce a sister-state judgment may examine whether the rendering court had jurisdiction over the parties and subject matter. But a judgment that appears to come from a court of general jurisdiction carries a presumption of jurisdiction unless the record itself or extrinsic evidence disproves it.
The Full Faith and Credit Clause does not permit the enforcing state to reconsider the merits of the original controversy, the logic or consistency of the rendering court’s decision, or the legal principles on which that decision rested. Even mistakes of law underlying a judgment do not make it unenforceable elsewhere once the rendering court had jurisdiction.
The Colorado Supreme Court therefore erred by holding the Wyoming decree facially void because Milliken’s earlier assignment to Transcontinental supposedly deprived him of a basis to recover from Meyer. That conclusion was an impermissible reassessment of the merits rather than a valid jurisdictional objection.
