WASHINGTON (AP) — The Supreme Court has turned away an appeal from sisters in western Pennsylvania who sued the local school system for its failure to stop another student from verbally and physically assaulting them in 2008.

Sisters Brittany and Emily Morrow contended that the Blackhawk School district in Pennsylvania's Beaver County had a constitutional duty to protect them from another student's bullying.

A deeply divided federal appeals court in Philadelphia upheld a trial judge's dismissal of the lawsuit. The justices said Monday they will not review that decision.

The case is Morrow v. Balaski, 13-302.
