Unable to predict whether Pennsylvania Supreme Court would hold Amazon strictly liable for a third-party vendor’s defective product, the U.S. Court of Appeals for the Third Circuit has sent the case to the state high court, asking it to weigh in.

The court’s decision came in the case of Oberforf v. Amazon.com, in which the plaintiff was injured when a dog leash, purchased on Amazon, broke and hit her in the face. The central question in case was whether the Restatement (Second) of Torts § 402A applies to Amazon.
