Does the failure of death penalty defense counsel to seek funding for an independent expert and not challenge the State's expert testimony constitute a violation of the Sixth Amendment right to effective assistance of counsel?

QUESTIONS PRESENTED 1. Does the failure of death penalty defense counsel to seek funding for an independent expert, coupled with the failure to challenge the State's flawed expert testimony before or during trial, constitute a violation of the defendant's Sixth Amendment right to effective assistance of counsel, when those omissions left key elements of the prosecution’s evidence in both the guilt and sentencing phases unchallenged? 2. Can a novel procedural rule be used by a state court in a death penalty case to preclude review of a federal constitutional claim?
