American Medical Assn. v. United States

Background

A group of medical organizations, two unincorporated associations, and several individual doctors were indicted and convicted for conspiring to prevent Group Health Association, Inc., a nonprofit cooperative started by Government employees, from operating. Group Health hired physicians on salary and arranged hospital care for members on a prepaid, risk-sharing basis. The indictment said the defendants coerced member doctors, blocked consultations, and pressured hospitals to deny facilities, all to stop Group Health’s plan.

Reasoning

The Court framed three questions: whether Group Health’s activities counted as business under the antitrust law, whether the indictment and evidence showed a conspiracy to restrain that business, and whether labor-law protections applied. The Court did not decide whether an individual doctor’s private practice is “trade,” because that question was unnecessary. It held that Group Health’s cooperative operations are business activity, that the indictment charged a single conspiracy to obstruct that business, and that a jury could reasonably find guilt. The Court also rejected the defendants’ claim of immunity under the Clayton and Norris-LaGuardia Acts, finding the societies were acting to stop a corporate business, not to resolve an employer-employee dispute.

Real world impact

The ruling means organized medical groups and hospitals can face antitrust criminal liability for coordinated efforts to block prepaid cooperative health plans. Associations cannot automatically claim labor-law exemptions when their aim is to prevent a competing corporate business. The opinion affirmed the convictions; two Justices did not participate in the decision.
