Roman v. Western Manufacturing examined a $1mm-plus verdict about severe injuries from a pump malfunction. No. 10-31271 (Aug. 17, 2012). After review of the standards, id. at 5 (“It is not our charge to decide which side has the more persuasive case.”), the Court found that two qualified mechanical engineers met Daubert even though they lacked extensive experience with “stucco pumps,” declining to “make expert certification decisions a battle of labels.” Id. at 7. The Court also rejected technical challenges to the type of pump reviewed by the experts and the plausibility of their factual assumptions about its operation, id. at 13 (“There was certainly contrary evidence, but that was for jurors to weigh.”), as well as sufficiency challenges about the inferences made by the jury. Id. at 16-17. Additional challenges were found waived under Fed. R. Civ. P. 50. This opinion is the latest in a series of thoughtful cases about Daubert after the 2009 decision in Huss v. Gayden.
