PORTLAND, Oregon — The question of whether two logging companies conspired to monopolize markets in an eastern Oregon forest came before a three-judge panel of the Ninth Circuit on Wednesday as a coalition urged the court to revive its antitrust challenge. US Circuit Judge Milan Smith noted the case was unlike other antitrust suits. …In 2013, the U.S. Forest Service granted the logging company Iron Triangle a 10-year stewardship contract for the Malheur National Forest, as well as associated logging rights. A group of landowners, loggers and an eastern Oregon lumber sawmill — known collectively as the Malheur Forest Coalition — sued Iron Triangle in 2022, arguing that the company exploited control of the contract and should be blocked from competing for harvest rights in U.S. Forest Service public auctions. The lower court denied the request, prompting a new complaint adding the Malheur Lumber Company as a defendant.
