Walton v. Arizona, 497 U.S. 639 (1990), was a United States Supreme Court case that upheld two important aspects of the capital sentencing scheme in Arizona — judicial sentencing and the aggravating factor "especially heinous, cruel, or depraved" — as not unconstitutionally vague. The Court overruled the first of these holdings in Ring v. Arizona, 536 U.S. 584 (2002). The second of these holdings has yet to be overturned.
