On Wednesday, the court’s conservative supermajority held that California’s law violates the Fifth Amendment, which bars the taking of private property for public use “without just compensation.” Remarkably, the majority held that the law constitutes a “per se taking”—not a mere regulation, but an “appropriation” of property that flouts the owners’ “right to exclude.” The court’s 6–3 decision in Cedar Point Nursery v. Hassid is thus a crushing blow to organized labor, which often relies on workplace access to safeguard workers’ rights. It also undermines the broader legal framework that permits the government to impose all manner of regulations on private property, including workplace safety laws and nondiscrimination requirements. With Cedar Point, the Supreme Court has handed business owners a loaded gun to aim at every regulation they oppose.
