Supreme court cannot overrule State Supreme Court on this as this is purely a North Carolina issue,not a Federal issue,-
State supreme court’s interpretation of any state law is generally final and binding to both state and federal courts. Federal courts may overrule a state supreme court decision only when there is a federal question which springs up a federal jurisdiction. An appeal from any state supreme court decision concerning matters of federal jurisdiction shall directly lie to the supreme court of the U.S. State supreme courts exercise both mandatory and discretionary review of appeals from trial courts.
