Hatch v. Trail King Indus., Inc.
Plaintiff, left paralyzed from the chest down after an accident at work, sued the company that built a specialized trailer for his employer. A jury rejected negligence and implied warranty of merchantability claims. The First Circuit affirmed. The district court acted within its discretion when it instructed the jury that a defendant who manufactures a product according to buyer specifications could not be liable under either a negligence or implied warranty theory unless the design defect was so obvious it would not have been reasonable for the defendant to manufacture according to the design.
