William O. Douglas,
D'Oench Duhme Company v. Federal Deposit Insurance Corporation…
“ A federal court sitting in a non-diversity case such as this does not sit as a local tribunal. In some cases it may see fit for special reasons to give the law of a particular state highly persuasive or even controlling effect, but in the last analysis its decision turns upon the law of the United States, not that of any state. Federal law is no juridical chameleon, changing complexion to match that of each state wherein lawsuits happen to be commenced because of the accidents of service of process and of the application of the venue statutes. ”
