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.

 (1890). It proscribed “unlawful restraints and monopolies” in interstate commerce as well as conspiracies to erect them. Soon thereafter federal judges began to employ the measure to combat efforts to unionize workers and to deny labor its traditional self‐help weapons.

Opinion of the Court

The Supreme Court reached the issue in Deering, a six‐judge majority holding that the Clayton Act did not insulate labor unions engaged in illegal activities, such as the conduct of a secondary boycott. Justice Mahlon Pitney

Subsequent history

For more than a decade, the majority's narrow interpretation of the nation's antitrust legislation sanctioned judicial application of injunctions against workers seeking to organize to advance their interests. With the dramatic transformation of opinion brought about by the Great Depression, Congress included in the Norris‐LaGuardia Act (1932) provisions to exempt organized labor from antitrust injunctions, and the Supreme Court legitimated this fundamental New Deal
