George Sutherland, Norton v. Larney — Opinion of the Court
“ It is quite true that the jurisdiction of a federal court must affirmatively and distinctly appear and cannot be helped by presumptions or by argumentative inferences drawn from the pleadings. If it does not thus appear by the allegations of the bill or complaint, the trial court, upon having its attention called to the defect or upon discovering it, must dismiss the case, unless the jurisdictional facts be supplied by amendment. ”
