- What it's about
The case concerns an Arizona death-row inmate’s claim that his lawyers were ineffective at the sentencing stage for failing to properly investigate and present mitigating evidence. The Supreme Court reviewed whether the Ninth Circuit wrongly granted federal habeas relief by failing to give the state court the deference required under AEDPA.
Question presented
Whether this Court should summarily reverse a fact-bound application of Strickland’s prejudice requirement in the context of Arizona’s now-obsolete judicial sentencing regime, where it is undisputed that counsel performed deficiently and failed to uncover a statutory mitigator and the panel correctly identified and applied the deferential governing standards from Strickland and this Court’s precedents interpreting and applying AEDPA.
