Osman v. Lin

Seventeen of the 20 plaintiffs to this case were Somali Bantu refugees who were resettled to the United States in 2004. Three of the plaintiffs were born in the United States to Somali Bantu refugees. Plaintiffs lived in the defendants’ apartments during 2005-2006, and those apartments were contaminated by lead paint, a known health hazard. Plaintiffs had elevated levels of lead in their blood. In their complaints, which were consolidated for discovery and trial, plaintiffs, through their parents, alleged that they were injured by their exposure to lead paint while living in defendants’ apartments. In this interlocutory appeal, plaintiffs challenged a superior court order granting the motion to exclude the expert testimony of Peter Isquith, Ph.D. After evaluating the 20 plaintiffs, Isquith, a clinical neuropsychologist, determined that 17 of them suffered from neurological deficits and opined that lead exposure was, more likely than not, a substantial factor in causing those deficits. The superior court excluded Isquith’s testimony based upon its determination that his testimony was not “the product of reliable principles and methods,” and its finding that he did not apply “the principles and methods reliably to the facts” of this case. The superior court certified a question to the Supreme Court: whether the trial court abused its discretion by excluding the expert's testimony. The Supreme Court found no reversible error in the trial court's order, and affirmed. View "Osman v. Lin" on Justia Law
