Fourth circuit affirms exclusion of expert testimony in pesticide case

In Bourne v. E.I. DuPont de Nemours & Co., the Fourth Circuit in a per curiam opinion for the panel of Judges Widener, Niemeyer, and Gregory affirmed the summary judgment for the defendant pesticide manufacturer, concluding that there was no error in excluding the testimony of plaintiff's expert on causation, in a case where plaintiffs claimed birth defects resulted from the mother's exposure to a fungicide called Benlate.
