No amendment "challenges" the death penalty. The 8th Amendment has been used as a legal basis for challenging the constitutionality of the death penalty. The argument is that the 8th Amendment prohibits "cruel and unusual punishment" and that the death penalty is cruel and unusual punishment and therefore is prohibited by the US Constitution. This argument was successful in earlier cases, not because the death penalty itself was cruel and unusual but because of the way it was administered. The death penalty is allowed if it is administered without racial or ethnic bias and in a non-cruel manner.
