Whether the business of organized professional baseball constituted interstate commerce subject to the Sherman Act.
Holding
No. The business was the presentation of baseball exhibitions, which the Court characterized as intrastate affairs rather than trade or commerce among the States.
Reasoning
The leagues organized clubs located in different cities and States to play paid public baseball games. Their structure required clubs and players to travel repeatedly across state lines, culminating in a championship contest between the leagues' pennant winners. But the Court treated those facts as describing arrangements that supported the games, not the commercial character of the underlying business.
In the Court's view, the essential business was giving baseball exhibitions for paying spectators. Those exhibitions occurred locally and were not, in the ordinary meaning of the terms, trade or commerce. The fact that the exhibitions were conducted for profit did not itself make them interstate commerce.
Interstate travel by teams and players was merely incidental to staging the exhibitions. Relying on the distinction reflected in Hooper v. California, the Court reasoned that incidental transportation does not transform a fundamentally local activity into interstate commerce.
The Court analogized baseball to a law firm sending a lawyer to another State to argue a case or a lecture bureau sending lecturers across state lines. In each example, the interstate movement facilitates a personal service but does not make the service itself interstate commerce. Because baseball was treated in the same way, the alleged restrictions on player contracts and the alleged effort to eliminate the Federal League did not interfere with commerce among the States under the Sherman Act.
