Facts

• Over 200 individuals brought an action against Shell Western Exploration and Production, Inc. and Shell Oil Company, alleging personal injury, property damage, or both due to the defendants' alleged purposeful or negligent contamination of the ground in the Westgate neighborhood in Hobbs, New Mexico, with various toxic petrochemicals. The plaintiffs resided in Westgate at different times over more than twenty years, an area situated within an active oilfield with a history of oil and gas operations since the 1920s. Shell maintained a tank battery on the site from 1946 to 1993 for storing crude oil and saltwater produced from wells on the lease and used an unlined storage pit, the Tasker pit, for disposing of oilfield waste. Contamination was detected at the former Grimes battery site and the Tasker pit area, leading to the discovery of hydrocarbon contamination in the soil and water table (paras 2-4).

Procedural History

• [Not applicable or not found]

Parties' Submissions

• Plaintiffs/Intervenors-Appellants: Argued that Shell purposely or negligently deposited various toxic petrochemicals in the ground, causing lupus and other autoimmune medical conditions among the plaintiffs. They sought to have Dr. Dahlgren testify as their expert witness regarding causation (paras 6-7).
• Defendants-Appellees: Challenged the plaintiffs' expert witness testimony on every claimed injury, including claims for respiratory, neurological, and psychiatric injuries. They argued that Dr. Dahlgren’s causation opinions relating to lupus and other autoimmune disorders were scientifically unreliable and lacked sufficient scientific support because his opinions relied solely upon his own epidemiologic study (para 9).

Legal Issues

• Whether the district court abused its discretion when it excluded Dr. Dahlgren’s expert opinions under Daubert and its New Mexico counterpart, State v. Alberico, and granted partial summary judgment on plaintiffs' claims relating to lupus and other autoimmune disorders (para 6).
• Whether the district court properly denied plaintiffs' motion for a new trial based on juror misconduct and juror bias (para 35).

Disposition

• The district court's grant of partial summary judgment in favor of defendants on plaintiffs' claims related to lupus and other autoimmune disorders was affirmed.
• The district court's denial of plaintiffs' motion for a new trial was affirmed (para 56).

Reasons

• The Court of Appeals held that the district court did not abuse its discretion in excluding Dr. Dahlgren’s expert opinions and granting partial summary judgment for the defendants because the scientific evidence available was insufficient to establish a proper scientific basis for Dr. Dahlgren to testify as to causation for plaintiffs' claims related to lupus or other autoimmune disorders. The court found that Dr. Dahlgren's study and other cited studies did not establish the necessary link between the specific chemical mixture and lupus or other autoimmune disorders (paras 20-33). Regarding the motion for a new trial, the court concluded that the juror affidavits presented by the plaintiffs were inadmissible under Rule 11-606(B) as they related to matters occurring during the course of the jury's deliberations or to the effect of anything upon the jurors' minds or emotions as influencing the verdict. The court found that the district court properly denied the motion for a new trial because the plaintiffs failed to demonstrate that any alleged juror bias or misconduct had a prejudicial impact on the verdict (paras 34-54).
