(January 11, 2017, 2:04 PM EST) -- PHILADELPHIA — A trial court erred when it ruled that a disparate-impact claim is not cognizable where a subgroup comprises workers 50 years old and older, a Third Circuit U.S. Court of Appeals panel ruled Jan. 10 in an opinion in which it also vacated the exclusion of testimony by the plaintiffs’ statistics expert and remanded for further Daubert proceedings (Rudolph A. Karlo, et al. v. Pittsburgh Glass Works, LLC, No. 15-3435, 3rd Cir.; 2017 U.S. App. LEXIS 406)....
