Phoenix. In 1952, while acting City Attorney, Hays worked to desegregate

Arizona House of Representatives as a Republican legislator from Maricopa County. He served in the
21st Arizona State Legislature from 1953 to 1954. In 1954, Hays was an Assistant United States Attorney. Hays spent seven years as the
United States Attorney for Arizona and ten years as a trial judge before being elevated to the Supreme Court. Hays was a noted conservative. Hays's judicial career began in 1960 when Arizona Governor
Paul Fannin appointed him to be a Maricopa County Superior Court Judge. During his time on the Superior Court, he was Maricopa County's only juvenile court judge. Hays was elected to the Supreme Court in 1968, taking his seat on January 4, 1969. On the bench, Hays wrote a notable dissent in
Grimm v. Board of Pardons & Paroles, writing, "Beware, oh unsuspecting trial judge, that when your decision to place a felon on probation goes horribly awry, the majority of my brothers sitting in cloistered ivory tower call your actions gross and subject you to the consequences thereof." Hays supported Arizona's transition from elected judges to a
merit selection system.
