  • Backus v. Nestlé USA, Inc., -- F. Supp. 3d --, 2016 WL 879673 (N.D. Cal. Mar. 8, 2016). Secured a ground-breaking victory for Nestlé USA and its iconic Coffee-mate brand when a federal judge in the Northern District of California dismissed with prejudice a consumer class action complaint.  Plaintiffs alleged that Nestlé’s mere use of partially hydrogenated oil in Coffee-mate was unlawful, and that labeling statements touting the product as having “0g Trans Fat” was misleading. The court ruled that plaintiff’s ‘use’ theory was an obstacle to federal law and therefore preempted, and that plaintiff’s false advertising theory, which attempted to impose labeling requirements not identical to federal law, was expressly preempted.
