It is currently a common if still relatively unheralded practice for a "fired" dealer to bring an antitrust action against his former manufacturer-supplier (and perhaps other dealers), alleging that his termination was the result of a boycott. Boycotts-collective efforts to obtain the exclusion of a party from a market-are illegal per se under section 1 of the Sherman Act. Thus, questions concerning the justification for the boycott or the significance of the offender's market position do not arise.
