Hugo Black,
Hazel-Atlas Glass Company v. Hartford-Empire Company…
“ The Circuit Court of Appeals is without authority either to try the issues posed by the petition and answer on the affidavits on file, or, to do as the dissenting judge below suggests, hold a full dress trial.The federal courts have only such powers as are expressly conferred on them. Certain original jurisdiction is vested in this court by the Constitution. Its powers as an appellate court are those only which are given by statute. ”
