In re the United States-South America Route Case

Background

The Government sued three principal companies tied to service between the United States and South America, seeking injunctive relief and divestiture for alleged antitrust violations. The Civil Aeronautics Board had meanwhile opened a comprehensive review of the U.S. flag carrier route pattern, noting three U.S. carriers serving South America and major changes in aircraft technology and foreign competition. The Board tentatively proposed an east-coast and a west-coast route structure and said it would consider new authorizations, deletions, and route consolidations.

Reasoning

The core question was whether courts could grant injunctions under the Sherman Act to block divisions of territories, allocations of routes, or combinations between carriers. The Court concluded that the economic regulation provisions governing air carriers displace the Sherman Act for injunctive relief in those kinds of route-and-territory disputes, and therefore the complaint asking for such relief should be dismissed and the matters left to the Board.

Real world impact

As a result, requests for court-ordered injunctions about who may serve which routes between the United States and South America are to be handled through the Board’s regulatory process rather than by immediate court action. That shift may limit the Government’s ability to obtain quick court divestiture orders; at the same time, the Board does not have authority to award money damages or to compel mergers or entirely terminate a carrier’s route, so some remedies may be constrained.

Dissents or concurrances

Justice Brennan (joined by the Chief Justice) dissented, arguing the decision wrongly displaces the antitrust laws, departs from precedent, and that courts should retain a role including use of the primary jurisdiction doctrine rather than barring judicial injunctive relief entirely.
