Louis Brandeis, Shannahan v. United States — Opinion of the Court
“ In order not to fail in the performance of these duties the Mediation Board had to satisfy itself whether the South Shore was a railroad within the exemption proviso. To that end, it applied to the Commission for its determination. If it had omitted to do so, the application might have been made 'upon complaint of any party interested.' The determination, whether applied for by the Board, by a carrier, or by employees, is clearly not an order enforceable within the meaning of the cases construing and applying the Urgent Deficiencies Act. ”
