In re TMI Litigation, Nuclear Reg. Rep. P 19,183, 193 F.3d 613, 45 Fed.R.Serv.3d 75

Facts

On March 28, 1979, a nuclear reactor accident at Three Mile Island released radioactive materials into the environment, leading to personal injury claims from over 2,000 area residents who alleged they developed neoplasms due to radiation exposure. The District Court consolidated these claims for pretrial proceedings and ordered a 'mini-trial' for a group of 'typical' plaintiffs to establish causation. The court held extensive hearings to determine the admissibility of expert testimony regarding radiation dose exposure, ultimately excluding most of it as unreliable, which led to the defendants' motion for summary judgment.

On March 28, 1979, radioactive materials were released into the environment as the result of an accident which occurred at Unit 2 of the Three Mile Island nuclear power generating station in Dauphin County ('TMI–2').

Issue

The main legal issues were whether the District Court properly excluded the scientific testimony of various experts as unreliable and whether the residents could establish causation for their injuries without that testimony.

The critical issue there is the trial plaintiffs' ability to demonstrate that they were exposed to doses of radiation sufficient to cause their neoplasms.

Rule

The court applied the Daubert standard for the admissibility of expert testimony, requiring that the testimony be both reliable and relevant to assist the finder of fact.

Following those hearings, the court excluded the overwhelming majority of the Trial Plaintiffs' proposed expert testimony as to dose exposure.

Analysis

The court found that the majority of the expert testimony regarding radiation dose exposure was inadmissible under the Daubert standard, as it was deemed scientifically unreliable. Consequently, without admissible evidence to establish the necessary radiation exposure levels, the residents could not prove causation for their neoplasms. The court also ruled that the exclusion of expert evidence as a sanction for discovery violations was not an abuse of discretion.

Accordingly, it ruled that the much of the expert testimony was inadmissible under Daubert, and its progeny.

Conclusion

The court affirmed the summary judgment in favor of the defendants against the Trial Plaintiffs, ruling that they failed to present sufficient evidence of radiation exposure. However, the court reversed the summary judgment for the Non-Trial Plaintiffs, allowing their claims to proceed.

Accordingly, the court granted summary judgment against all of the plaintiffs, both trial and nontrial.

Who won?

The defendants prevailed in the case because the court found that the plaintiffs could not establish the necessary causation due to the exclusion of expert testimony on radiation exposure.

The court finds that resolution of the issue before it turns on the grounds upon which the court ultimately grants or denies summary judgment.
