On appeal, the United States Supreme Court ruled that the criminalization of interracial sex was not a violation of the equal protection clause because whites and non-whites were punished in equal measure for the offense of engaging in interracial sex. The court did not need to affirm the constitutionality of the ban on interracial marriage that was also part of Alabama's anti-miscegenation law, since the plaintiff, Mr. Pace, had chosen not to appeal that section of the law. After "Pace v. Alabama", the constitutionality of anti-miscegenation laws banning marriage and sex between whites and non-whites remained unchallenged until the 1920s.
