Background
Briley Piper was convicted of first-degree felony murder and sentenced to death for the 2000 killing of Chester Allan Poage in South Dakota. After his death sentence was vacated and reinstated by a jury following a state court ruling on jury sentencing, Piper filed multiple state and federal habeas corpus petitions. The district court denied all thirteen claims and granted a certificate of appealability on four, which the Eighth Circuit later expanded to six claims for review.
The court’s reasoning
The Eighth Circuit reviewed six claims. First, the court rejected the argument that Loper Bright invalidated AEDPA deference, noting that federal courts must still find state court decisions objectively unreasonable. Second, the court affirmed that Piper’s claim regarding his guilty pleas was procedurally defaulted under South Dakota’s res judicata doctrine, which is an independent and adequate state ground. Third, the court found no abuse of discretion in denying an evidentiary hearing on fetal alcohol spectrum disorder, as the record showed counsel had investigated mental health issues without finding red flags. Fourth, the court held that failing to impeach a witness with rape convictions would not have changed the outcome given the overwhelming evidence of the crime and the witness’s already damaged credibility. Fifth, the court found no prejudice in the failure to rebut the state’s suggestion that a nun violated prison rules, as the mitigating evidence was extensive and the jury found aggravating factors outweighed them. Finally, the court ruled that cumulative prejudice cannot serve as a basis for habeas relief when no individual error is established.
Because Piper has failed to show that he is entitled to relief on any of the six claims before us, we affirm.

What it means going forward
The decision reinforces the narrow scope of federal habeas review for state prisoners and confirms that procedural defaults based on state res judicata rules will bar federal claims even when the petitioner argues novel applications of state law.
