Whether the Sixth Amendment permits a judge, rather than a jury, to find an aggravating circumstance that Arizona law requires before a death sentence may be imposed.
Holding
No. Any aggravating fact necessary to raise a defendant's maximum authorized punishment from life imprisonment to death must be found by a jury beyond a reasonable doubt.
Reasoning
Apprendi establishes that a defendant may not be exposed to a punishment exceeding the maximum authorized by the facts reflected in the jury's verdict alone. The relevant question is the practical effect of the statutory scheme, not whether the State places the relevant fact in an offense provision or calls it a sentencing factor.
The Arizona Supreme Court's authoritative construction of its own law established that Ring's felony-murder verdict alone authorized no more than life imprisonment. Death became legally available only after the judge found at least one statutory aggravating circumstance. That aggravating circumstance therefore increased Ring's maximum punishment.
Arizona's description of first-degree murder as punishable by either life or death did not alter the result. Its murder statute expressly incorporated the separate capital-sentencing provision, which made a judicial finding of an aggravator a prerequisite to death. Accepting Arizona's formal characterization would allow legislatures to evade Apprendi through statutory drafting.
The distinction between an element and a sentencing factor could not save Arizona's scheme. When a fact increases the maximum punishment authorized by the jury verdict, it is the functional equivalent of an element of a greater offense, whatever label the legislature assigns it.
Capital defendants are not an exception to Apprendi. Although the Eighth Amendment requires States to narrow and guide the class of defendants eligible for death, that requirement supplies no reason to deny capital defendants the Sixth Amendment protection extended to defendants facing lesser increases in punishment. The Court also rejected the suggestion that judge factfinding is necessarily more fair or efficient, observing that the jury-trial guarantee does not depend on comparative assessments of factfinders.
