Genereux v. Raytheon Co.

Plaintiffs filed a putative class action in the United States District Court for the District of Massachusetts, invoking federal diversity jurisdiction, alleging that Defendant, Raytheon Company, negligently exposed Plaintiffs and others similarly situated to beryllium. Plaintiffs’ principal theory of liability was that the beryllium exposure caused subcellular change. Plaintiffs alternatively argued that a cause of action for medical monitoring under Massachusetts law does not require a showing of subcellular or other physiological change. The district court granted summary judgment in favor of Defendant. The First Circuit affirmed, holding (1) because no named Plaintiff or any class member had as yet contracted beryllium sensitization, the first manifestation of subcellular change resulting from beryllium exposure, Plaintiffs’ first claim failed; and (2) Plaintiffs did not preserve a claim under their alternative theory.
