Cunningham v. California
The Supreme Court struck down California's determinate sentencing law, ruling that letting a judge add years to a sentence based on facts the judge alone found violated the constitutional right to a jury trial.
The decision extends earlier rulings limiting judge-only fact-finding in sentencing, forcing California to overhaul how tens of thousands of criminal sentences are decided each year.
“In other words, the relevant ‘statutory maximum’ is not the maximum sentence a judge may impose after finding additional facts, but the maximum he may impose without any additional findings.”
Explains the key legal test for what counts as the true statutory maximum sentence.
How it got here: A California appeals court affirmed the sentence; the California Supreme Court denied review after upholding the law in a separate case; the U.S. Supreme Court agreed to hear Cunningham's appeal.
The Case in Depth
What happened
John Cunningham was convicted of continuous sexual abuse of a child under California's determinate sentencing law, which set three possible prison terms: 6, 12, or 16 years. A judge, after a post-trial hearing, found aggravating facts by a preponderance of the evidence and sentenced Cunningham to the maximum 16-year term instead of the standard 12-year middle term.
The question before the Court
Could a California judge, rather than a jury, add years to a defendant's prison sentence just by finding extra facts by a mere preponderance of the evidence?
The Court's answer
No — the Constitution's jury-trial guarantee does not allow a judge to add years to a sentence based on facts the judge alone found by a mere preponderance of the evidence. The Court held that California's determinate sentencing law violated the Sixth and Fourteenth Amendments because it let judges, rather than juries, find the aggravating facts needed to move a defendant's sentence from the standard 12-year middle term up to the 16-year upper term, using a lower standard of proof than the beyond-a-reasonable-doubt standard a jury must use.
The Court rejected California's argument that its system was similar to the advisory federal sentencing guidelines approved in an earlier case, explaining that California's three fixed sentencing options gave judges no true discretion to pick a sentence within an open range — they were locked into the middle term unless they found extra facts themselves. That distinction meant California's law, unlike the advisory federal system, crossed the constitutional line.

Why it matters
Criminal defendants in California can no longer have their sentences increased based solely on facts a judge finds after trial by a lower standard of proof. The state had to redesign its sentencing system, and other states with similar fixed-term sentencing laws faced pressure to ensure juries, not judges, decide facts that increase punishment.
What changes now
The case was sent back to California courts for further proceedings consistent with the ruling. The Supreme Court left it to California to redesign its sentencing system, noting other states had already amended similar laws after earlier rulings by having juries find sentence-enhancing facts or by giving judges truly open-ended discretion. This is a final merits ruling, not a temporary order, though its practical application to California's sentencing scheme required legislative or judicial follow-up.
What this does not decide
The Court did not decide how the more lenient 'reasonableness' standard used to review federal sentences after Booker should work in practice, explicitly reserving that question for two other pending cases, Claiborne and Rita, argued later that term.
Concurrences and dissents
Dissent — Justice Kennedy
Justice Kennedy argued the Apprendi line of cases was wrongly decided and urged a distinction between facts about the offense (where jury fact-finding should be required) and facts about the offender's background, like prior record or remorse (where judges should retain discretion). He would have allowed California's system of guided discretion to stand rather than treating it as constitutionally forbidden.
Dissent — Justice Alito
“The California sentencing law that the Court strikes down today is indistinguishable in any constitutionally significant respect from the advisory Guidelines scheme that the Court approved in United States v. Booker”Alito's core objection that California's law was no different from the approved federal guidelines system.
Justice Alito argued California's law was functionally identical to the advisory federal sentencing guidelines the Court had upheld in Booker, since both required judges to justify above-minimum sentences with some factual finding subject to reasonableness review on appeal. He would have upheld California's system and affirmed the sentence.
How the Court got there
The legal reasoning, step by step
- The Court applied the rule from Apprendi v. New Jersey: any fact, other than a prior conviction, that increases a defendant's sentence beyond the maximum allowed by the jury's verdict alone must be found by a jury beyond a reasonable doubt, not by a judge using a lower standard of proof.
- Drawing on Blakely v. Washington, the Court explained that the 'statutory maximum' for this purpose is not the highest sentence a judge could ever impose, but the highest sentence a judge could impose using only the facts the jury already found or the defendant admitted.
- The Court compared California's law to the federal sentencing guidelines struck down in United States v. Booker, noting both systems bound judges to specific outcomes unless they found extra facts, which is different from a truly discretionary system where a judge freely picks a sentence within a range.
- Applying these principles, the Court identified California's 12-year 'middle term' as the true statutory maximum, because a judge could not go above it without finding additional aggravating facts on his or her own.
- The Court rejected California's argument that its sentencing law was comparable to the advisory federal guidelines system approved in Booker, reasoning that California's fixed three-tier system left judges no true discretion to pick a sentence within a range the way the advisory federal guidelines did.
- Because the extra fact-finding needed to reach the 16-year term was done by a judge under a preponderance standard rather than by a jury beyond a reasonable doubt, the Court concluded the law violated the jury-trial guarantee.
