What is Refusal to Deal under the Sherman Act?

Under the Sherman Act 1, refusals to deal with or boycotts of market participants can be illegal as horizontal restraints of trade. This may be the case when the refusal has anti-competitive aspects but no pro-competitive justification. If the refusal to deal is not a pure restraint of trade, a court would use the rule of reason to determine whether a sufficient restraint of trade is present to make the conduct illegal. The greater the amount of commerce involved in the boycott situation, the more likely it is to be an illegal restraint of trade.

Example: A boycott of a supplier that includes cooperative buying arrangement would be per se illegal if the boycotters possess extensive market power or control some element that is essential for competition. If, on the other hand, an agreement to boycott a particular supplier is suggested, it may not be a restraint of trade. But, if the boycott is monitored by either party and enforced in some manner, it is likely a sufficient restraint on trade to be illegal.
