Ninth Circuit's Cemex Ruling Leaves GCs in Labor Law Limbo

On April 21, 2026, the Ninth Circuit affirmed the NLRB’s Cemex decision against Cemex Construction Materials Pacific, upholding the Board’s remedies. The court did not, however, rule on whether the new standards established in the Cemex decision are themselves lawful. That question, the one contractors have been waiting on, remains unanswered. The article covers the ruling’s scope, what was affirmed, and what was deliberately left open.

This is the worst kind of legal outcome for GC principals trying to plan: a decision that confirms liability without settling the rule. The Cemex standard dramatically lowered the bar for union recognition, and the Ninth Circuit just enforced it without endorsing it. That distinction matters in practice. GCs operating in the Ninth Circuit’s jurisdiction, Alaska, Arizona, California, Hawaii, Idaho, Montana, Nevada, Oregon, and Washington, are now exposed to Cemex remedies with no appellate clarity on whether the underlying standard will survive broader scrutiny. Talk to labor counsel before the next organizing contact happens on one of your job sites. Waiting for a cleaner ruling is not a plan.
