Pick Manufacturing Co. v. General Motors Corp.

Background

A dealer challenged a clause used by General Motors’ selling organizations (Chevrolet and Buick) that forbids dealers from selling or using second‑hand or non‑manufacturer parts and says dealers have no exclusive right to genuine new parts. The dealer sued under the Clayton Act, and the trial court found the clause did not substantially reduce competition or create a monopoly. The District Court dismissed the complaint and the Court of Appeals affirmed that dismissal.

Reasoning

The core question was whether those contract terms violated the Clayton Act by harming competition. The Supreme Court applied the rule that it accepts factual findings agreed to by two lower courts unless a clear error is shown. Because the trial record supported the finding that the clause did not substantially lessen competition or create a monopoly, the Court affirmed the lower courts’ ruling and upheld the dismissal.

Real world impact

The decision means that, on the facts in this case, auto manufacturers’ rules barring dealers from using or selling used or non‑manufacturer parts can be allowed so long as courts find no substantial competitive harm. Dealers who want to sell or use aftermarket or used parts may be limited where the evidence shows no anticompetitive effect. This ruling affirms the importance of trial record evidence in antitrust challenges and does not change outcomes in cases with different factual findings.

Dissents or concurrances

Three Justices—Van Devanter, Stone, and Roberts—took no part in the consideration or decision, a procedural note but not a disagreement in opinion on the merits.
