William Strong, Beard v. Burts — Opinion of the Court
“ It is obvious the only important inquiry respects the validity of the authority under which the defendant had acted. It claimed to be a privilege or immunity under the laws of the United States. It was found to be authentic by the Chancellor in his original decree, and its authenticity is not denied in the bill of review. That, therefore, is not open to debate. To sustain a bill of review, there must be errors of law apparent on the face of the decree, or some new matters of fact material in themselves, and discovered after the rendition of the decree. ”
