More than three years after the case changed the definition of products liability in Pennsylvania, Tincher v. Omega Flex has been sent back for a new trial.

On Friday, a unanimous three-judge panel of the state Superior Court determined that product manufacturer Omega Flex was entitled to a new trial on claims that its gas transportation system was defective. The decision, which reversed the trial court’s ruling, highlighted the importance of jury instructions that outline the revamped definition of “defect.”
