Acosta v. Shell W. Expl. & Prod., Inc.Annotate this Case
Environmental contamination from Shell Western Exploration and Production, Inc. and Shell Oil Company's operations was discovered in Hobbs. Residents near the area brought a toxic tort action against Shell for personal injury damages, alleging the contaminants cause their autoimmune disorders. Plaintiffs challenged the district court's exclusion of the scientific evidence and expert testimony they offered in support of their theory, and they challenged the grant of partial summary judgment in favor of Shell. After review, the Supreme Court concluded the district court applied an incorrect standard of admissibility in its evidentiary rulings, and that plaintiffs' causation evidence should have been admitted. Because summary judgment to Shell's culpability for autoimmune disorders was granted because of this improper exclusion, the Supreme Court reversed and remanded for further proceedings.
