Felix Frankfurter,
Estep v. United States — Concurrence
“ Surely it would hamper the aim of Congress to subject the decisions of the selective process in determining who is amenable to service to reconsideration by the cumbersome process of trial by jury, admirably suited as that is for the familiar controversies when the nation's life is not at stake. To avoid such a palpable inroad upon Congressional purpose, we need not draw on implications. We must merely resist unwarranted implications to sterilize what Congress has expressly required. ”
