Can a defendant appeal his conviction for a second time against the death penalty?

Id. at 961 (citing Sanders v. United States, 373 U.S. 1, 18, 83 S.Ct. 1068, 1078, 10 L.Ed.2d 148 (1963)). Richmond may also renew challenges to the death penalty that were raised in his first petition and decided against him by the district court:

[W]hen the district court enjoined Richmond's [initial] death sentence, it relied solely on the [original] Arizona statute's failure to consider mitigating factors of an individual's character. Richmond v. Cardwell, 450 F.Supp. at 526. Because Richmond had obtained the sentencing relief he sought, he had no incentive to appeal the adverse determination of his other grounds for challenging the death sentence, and perhaps would not have been permitted to do so on mootness or ripeness grounds. The ends of justice would not be served by denying Richmond appellate consideration of these other constitutional challenges to the death penalty merely because he obtained relief on a different ground.
