Justice O'Connor wrote an opinion for herself,
Chief Justice Rehnquist, and
Justice Kennedy. Under the Eighth Amendment, a narrow proportionality principle applies to non-capital sentences. Before
Ewing, the Court had from time to time examined lengthy sentences imposed for relatively minor crimes. In
Rummel v. Estelle, the Court upheld a life sentence for obtaining $120.75 by false pretenses imposed on a three-time offender under Texas's recidivist statute. In
Solem v. Helm, the Court struck down a
life without parole (LWOP) sentence imposed on a defendant who had committed a seventh non-violent felony. Most recently, in
Harmelin v. Michigan, the Court upheld a life without parole sentence imposed on a first-time offender convicted of possession of more than 650 grams of cocaine. Against this backdrop of case law, O'Connor said that the gross disproportionality principle contained in the Eighth Amendment would require striking down only an extreme noncapital sentence, such as a life sentence for overtime parking. Three-strikes laws, O'Connor observed, represented a new trend in criminal sentencing. "These laws respond to widespread public concerns about crime by targeting the class of offenders who pose the greatest threat to public safety: career criminals." Such laws were a "deliberate policy choice" on the part of legislatures to isolate those who have "repeatedly engaged in serious or violent criminal behavior" from the rest of society in order to protect public safety. For O'Connor, the desire to punish repeat criminals more harshly was "no pretext" for the legitimate policy choice that the three-strikes law implemented. Such laws serve the valid penological goals of incapacitation and deterrence. Although California's three-strikes law may have generated some controversy, "we do not sit as a superlegislature to second-guess" the policy choices made by particular states. "It is enough that the State of California has a reasonable basis for believing that dramatically enhanced sentences for habitual felons advances the goals of its criminal justice system in any substantial way." She noted that Ewing's crime was not simply that of stealing three golf clubs—it was stealing three golf clubs after being convicted of two violent or serious felonies. "In weighing the gravity of Ewing's offense, we must place on the scales not only his current felony, but also his long history of felony recidivism. Any other approach would fail to accord proper deference to the policy judgments that find expression in the legislature's choice of sanctions." Ewing's sentence might be long, but it "reflects a rational judgment, entitled to deference, that offenders who have committed serious or violent felonies and who continue to commit felonies must be incapacitated." For this reason, O'Connor reasoned that Ewing's 25-years-to-life sentence did not violate the Eighth Amendment.
Justice Scalia was willing to accept that the Eighth Amendment contained a gross disproportionality requirement "if I felt I could intelligently apply it." However, because a criminal sentence can have many justifications—not simply retribution, a goal to which proportionality is inherently linked— he thought it was impossible to intelligently apply a proportionality requirement to non-capital sentences. Even so, Justice Scalia concurred in the judgment that Ewing's sentence was constitutional.
Justice Thomas believed that the Eighth Amendment contained no proportionality principle at all, and concurred in the judgment. ==Dissents==
