The state has asked the Nebraska Supreme Court to dismiss the latest appeal from condemned killer Michael Ryan.
Attorney General Jon Bruning says Monday that the court should reject the appeal because there's no doubt about Ryan's guilt and the "meritless appeals only serve to delay justice."
Ryan was sentenced to death for cult-related killings in 1985 in the southeast Nebraska town of Rulo.
The court in February put Ryan's execution on hold while he pursued a lower court challenge to how Nebraska obtained one of three drugs that would be used to execute him.
The state is resisting an order to turn over to federal authorities the state supply of the drug, sodium thiopental.
