William O. Douglas,
Milliken v. Meyer — Opinion of the Court
“ In its view the finding of the Wyoming court that Milliken's assignment of May 3, 1924, to Transcontinental of his claims against Meyer was valid, deprived the court of any ground upon which it could predicate a judgment against Meyer, since the only basis for an action by Milliken against Meyer rested upon the claim before its assignment.Where a judgment rendered in one state is challenged in another, a want of jurisdiction over either the person or the subject matter is of course open to inquiry. ”
