Summary

Louis Brandeis The Assigned Car Cases — Opinion of the Court

Coal cars of railroad ownership, other than those assigned to the loading of railroad fuel coal, are known and will be referred to as 'system cars.' Car distribution rules assume importance only in times of car shortage; that is to say, when car orders exceed car supply. To provide for such periods the capacity of such mine is rated in cars per day. A mine may order cars each day up to but not exceeding its rated capacity and in time of a car shortage generally does so (even though it might not actually have equivalent orders for coal) in order that it may get as many cars as possible.

Louis Brandeis The Assigned Car Cases — Opinion of the Court

The Commission found that the existing assigned car practice reduces to a certain extent the supply of cars furnished to commercial mines; that the larger and steadier supply of cars gives the assigned car mines a great advantage in steadiness of operation, and hence in cost of production, in the selling markets, and in the labor market; and that, apart from the discrimination inherent in the assigned car rule, the carriers have been guilty of other willful discriminatory practices, which, as a practical matter, it would be difficult to prevent as long as the rule prevailed.

Louis Brandeis The Assigned Car Cases — Opinion of the Court

If the order was intended to enlarge the total supply of cars of bring about more equitable distribution of available cars in times of shortage, it was foolish. Supply cannot be increased, nor equitable distribution enforced, by prohibiting the use of private or fuel cars when most needed-requiring them to stand idle, on the sidings. If, on the other hand, as I must think, the real purpose was to force large consumers of scatter their purchases, the order goes beyond any power intrusted to the Commission.
