Joseph McKenna, Interstate Commerce Commission v…
“ It is true there may be a jurisdiction to determine the possession of jurisdiction. Ex parte Harding, 219 U.S. 363, 55 L. ed. 252, 31 Sup. Ct. Rep. 324. But the full doctrine of that case cannot be extended to administrative officers. The Interstate Commerce Commission is purely an administrative body. It is true it may exercise and must exercise quasi judicial duties, but its functions are defined, and, in the main, explicitly directed, by the act creating it. It may act of its own motion in certain instances,-it may be petitioned to move by those having rights under the act. ”
