Tyson, Cargill Challenge Class-Action Ruling in Cattle Price-Fixing Case

The meatpackers filed arguments with the U.S. Court of Appeals for the Eighth Circuit on Oct. 7, seeking to reverse a July 16 ruling by U.S. District Judge John Tunheim in Minnesota, according to an Oct. 12 report by Meatingplace.

The companies dispute allegations that they coordinated cattle purchases and slaughter operations to reduce prices paid to ranchers and feedlot operators. They also contend that the producers have failed to demonstrate that common evidence can establish financial harm across the proposed class, according to Meatingplace.

The appeal focuses on whether cattle producers can pursue their claims collectively rather than through separate lawsuits, a distinction that could have substantial financial and legal consequences for both sides.

The certified class includes producers who sold fed cattle to the defendant companies between June 1, 2015, and Feb. 29, 2020, according to Meatingplace.

At the center of the litigation are allegations that major beef processors periodically restricted cattle purchases and slaughter activity, creating an oversupply of market-ready animals and weakening producers’ negotiating position.

The plaintiffs argue that those practices artificially lowered cattle prices in violation of federal antitrust law. An economic analysis presented on their behalf by Russell Lamb estimated that prices were 6.7% below levels that would have prevailed without the alleged coordination, Meatingplace reported.

The processors reject the conspiracy allegations and challenge whether the economic evidence can establish that individual producers experienced comparable losses.

Their appeal raises questions about the standards courts must apply when determining whether an antitrust case can proceed as a class action. The companies argue that the district court improperly placed part of the burden of disproving classwide injury on the defendants, rather than requiring the plaintiffs to establish it.

The dispute is part of broader litigation involving major U.S. beef processors and allegations of anticompetitive conduct in cattle and beef markets.

JBS, another major processor initially named in the cattle producers’ case, previously agreed to an $83.5 million settlement that received court approval in August 2025, according to Meatingplace. The settlement left Tyson, Cargill and National Beef contesting the producer claims.

Court records show that the companies initially sought permission to appeal the class-certification decision on July 30. The matter subsequently moved forward under a separate appellate docket in August.

The outcome could influence how cattle producers seek compensation for alleged historical losses and how courts evaluate economic evidence in complex antitrust disputes.

A ruling in favor of the processors could undermine the producers’ ability to pursue damages as a unified group. If the certification is upheld, the cattle producers would retain a collective legal mechanism for advancing their claims.
