Louisiana challenges the district court’s grant of habeas relief to an inmate who had been convicted of first-degree murder and sentenced to death in 2009. The district court held that ineffective assistance of trial counsel prejudiced the defense. The State argues that the district court applied the incorrect standard of review under the Antiterrorism and Effective Death Penalty Act of 1996, and that the district court improperly granted habeas relief due to ineffective assistance of counsel under Strickland v. Washington, 466 U.S. 668 (1984).
