Answer: Woodson v North Carolina and Roberts v Lousianna
Step-by-step explanation:
In Boykin v. Alabama (1969), the Supreme Court examined the constitutionality of the death penalty for the first time.
By 1972, Furman v. Georgia ruled a Georgia death penalty law was cruel and unusual punishment, which is forbidden by the Eighth Amendment. In 1976 there were five "Death Penalty Cases". While Gregg v. Georgia, Jurek v. Texas, and Proffitt v. Florida, confirmed the states´ death penalties, Woodson v. North Carolina and Roberts v. Louisiana overturned the mandatory death sentences.
