Summary

Background

Six American maritime unions picketed the Aqua Glory, a Liberian-flag ship, at the Port of Mobile to protest low foreign seamen wages. Their signs and handbills urged the public not to patronize the ship. The picketing led longshoremen and stevedores to refuse to cross the lines, halting cargo handling. Mobile Steamship Association and a shipper sued in Alabama state court and obtained a temporary injunction, which the Alabama Supreme Court affirmed and remanded for trial. The unions asked this Court to decide whether federal labor law blocked state court actions and whether the injunction violated free‑speech protections.

Reasoning

The Court addressed whether the National Labor Relations Act required exclusive review by the NLRB and whether the injunction violated the First and Fourteenth Amendments. Relying on Windward and related precedents, the majority held the NLRA did not preempt state-court jurisdiction because the picketing’s effect on foreign vessels’ maritime operations placed it outside the Act’s reach for Board jurisdiction. The Court also applied prior picketing free‑speech law and found evidence that the picketing sought to induce work stoppages and wrongfully interfere with respondents’ businesses, so the temporary injunction fell within the trial judge’s equitable discretion.

Real world impact

The decision lets state courts enjoin similar dockside picketing that causes stevedores or longshoremen to stop handling cargo and threatens port operations, rather than forcing those disputes first to the NLRB in such circumstances. Stevedores, shippers, and farmers who face disrupted shipments can seek local equitable relief. Because this case affirmed only a temporary injunction and remanded for trial on the merits, the final outcome could still change after a full hearing.

Dissents or concurrances

Four Justices dissented, arguing that the secondary dispute clearly affected commerce and that the National Labor Relations Board had exclusive jurisdiction; they would have reversed the Alabama courts and left resolution to the federal labor agency.
