Whether state courts must reopen mitigation evidence in every death-penalty remand when the original error did not affect the defendant's opportunity to submit mitigating evidence

This Court’s precedent in Lockett , Eddings , and Skipper require that state courts admit and consider all relevant mitigating evidence that a death -eligible convict wants to present. And when the state courts fail to do so, this Court has remanded for them to fix the error. The question is: Has this Court clearly required state courts to reopen the mitigation eviden ce in every death -penalty remand, even if the error did not affect the defendant’s opportunity to submit mitigation evidence?
