Duplex Printing Press Co. v. Deering 41 S. Ct. 172 (1921) is a United States Supreme Court case which examined the labor provisions of the Clayton Antitrust Act and reaffirmed the prior ruling in Loewe v. Lawlor that a secondary boycott was an illegal restraint on trade. The decision authorized courts to issue injunctions to block this practice and any other tactics used by labor unions that were deemed unlawful restraints on trade.
