OPINION
NOONAN, Circuit Judge:Rick Wilson appeals the denial of his petition for a writ of habeas corpus. Holding that the California courts violated Wilson’s right to due process under Apprendi v. New Jersey, 530 U.S. 466, 120 S.Ct. 2348, 147 L.Ed.2d 435 (2000), we reverse the judgment of the district court and remand.
BACKGROUND
In 1993, Wilson pleaded no contest to gross vehicular manslaughter while driving under the influence of alcohol in violation of California Penal Code § 191.5(a), and to proximately causing bodily injury while driving under the influence of alcohol in violation of California Vehicle Code § 23153(b). There was a preliminary hearing but no trial. He served one year of imprisonment in a residence for the treatment of addiction.
Both convictions resulted from a single accident. Wilson had driven with his girlfriend Deborah Horvat from Reno, Nevada into California. At some point, Horvat gave Wilson the keys and asked him to drive. They picked up a hitchhiker, John Haessly, along the way. Wilson had been drinking and drove at a high rate of speed. The car veered off the road and flipped over. Haessly was killed, and Horvat was injured.
PROCEEDINGS
In the latest case, Wilson was convicted in 2000 by a jury of driving under the influence with a prior felony conviction. See Cal. Veh.Code §§ 23152(a), 23550.5. The trial judge found this conviction to be Wilson’s third strike under California Penal Code § 667(b)-(i). The judge in 2000 found that the 1993 convictions counted as the first and second strikes. He sentenced Wilson to imprisonment for 25 years to life.
The prosecutor in 2000 had introduced numerous documents, including the information and preliminary hearing transcript from 1993, to establish that the conviction for injuring Horvat should count as a strike. The trial judge in 2000 examined this evidence and announced: “So I feel the evidence presented does satisfy me that — and I’ll make additional findings as well that the prior conviction alleged for felony driving under the influence of alcohol with ... personal infliction with great bodily injury alleged as first prior conviction within the meaning of 667(b) through 667(i) and 1170.12, that that allegation is true.”
The California Court of Appeal affirmed Wilson’s sentence. Justice Rushing dissented and would have found that the trial court violated Apprendi Wilson presented the issue to the state supreme court, which denied his petition for review on the merits.1 Wilson then sought federal habeas relief. The district court denied his *1215petition, holding that “there is no ‘clearly established’ federal right to jury trial in determining the legal significance of a pri- or conviction.”
Wilson appeals.
ANALYSIS
The Standard of Review. We review a district court’s denial of a habeas petition de novo. Lopez v. Thompson, 202 F.3d 1110, 1116 (9th Cir.2000) (en banc). We review the state court’s ruling under the Antiterrorism and Effective Death Penalty Act of 1996 (AEDPA) because Wilson filed his petition after AEDPA entered into effect. Martinez v. Garcia, 379 F.3d 1034, 1037 (9th Cir.2004). We may grant habeas relief only if the state court’s decision was “contrary to, or involved an unreasonable application of’ clearly established Supreme Court precedent, or “was based on an unreasonable determination of the facts.” 28 U.S.C. § 2254(d)(l)-(2).
Apprendi Error. The Supreme Court held in Apprendi that, except for the fact of a prior conviction, any facts that increase a defendant’s sentence beyond the statutory maximum must be proved to a jury beyond a reasonable doubt. See Apprendi 530 U.S. at 490, 120 S.Ct. 2348. The trial judge in this case in 2000 found three additional facts about the 1993 accident that increased Wilson’s sentence to 25 years to life: First, that Wilson personally inflicted bodily injury on Horvat; second, that the injury was great; and third, that the victim was not an accomplice. These facts weren’t necessary to Wilson’s 1993 conviction, and there was no purpose in his challenging them at the time of that conviction in 1993. The issue is whether these findings made in 2000 fell within the prior conviction exception.
Courts may reasonably disagree about some of the precise boundaries of the exception. See Kessee v. Mendoza-Powers, 574 F.3d 675, 676 (9th Cir.2009). For example, it isn’t clearly established whether a judge may find the fact that a defendant was on probation at the time of an earlier conviction. Id. at 678. But that does not mean that Apprendi is amorphous. It would be unreasonable to read Apprendi as allowing a sentencing judge to find the kinds of disputed facts at issue here — such as the extent of the victim’s injuries and how the accident occurred.2 These are not historical, judicially noticeable facts. The judge in 2000 speculated as to how a jury in 1993 might have evaluated the evidence if the evidence had been offered and if a jury had been impaneled to evaluate it. See United States v. Brown, 417 F.3d 1077, 1079-80(9th Cir.2005) (per curiam). Wilson did not have any reason to contest these alleged facts when he was convicted in 1993. See Apprendi 530 U.S. at 488, 120 S.Ct. 2348 (emphasizing importance of procedural safeguards during earlier proceeding). The judge’s fact-finding seven years after the 1993 conviction extended beyond any reasonable interpretation of the prior conviction exception. See *1216DeWeaver v. Runnels, 556 F.3d 995, 997(9th Cir.2009) (explaining that the state court violates the “unreasonable application” prong when it “extends or fails to extend a clearly established legal principle to a new context in a way that is objectively unreasonable”) (citation and internal quotations marks omitted). It is utterly unreasonable to hold that what a judge in 2000 imagines might have happened in 1993 is the same as a conviction in 1993.
The harm. The fallback position of the government is that the error was harmless. To make that argument work, the government imagines what would have happened if in 1993 Wilson had been charged with the infliction of great bodily injury and gone to trial. But we really don’t know what would have happened. Wilson might have created reasonable doubt as to whether Horvat caused the accident by grabbing the steering wheel or acted as an accomplice by giving a drunk Wilson her keys. See, e.g., People v. Verlinde, 100 Cal.App.4th 1146, 123 Cal. Rptr.2d 322, 334 (2002). Wilson might also have successfully challenged the prosecution’s evidence about the extent of Horvat’s injuries. No court could now look at the disputed facts about 'an accident seven years earlier and conclude beyond a reasonable doubt that Wilson would have been convicted of personally inflicting great bodily injury. Wilson’s first strike, as determined by the court in this case, does not exist. It is a crime created by speculation as to what might have been shown in 1993.
The state’s petition for rehearing has afforded opportunity to take into account the Supreme Court’s summary of its habeas jurisprudence in Harrington v. Richter, — U.S.-, 131 S.Ct. 770, 178 L.Ed.2d 624 (2011). No reasonable judge could rule that a conviction of causing bodily injury was the same as a conviction of causing great bodily injury. No reasonable judge could hold that a charge that might have been made and proved is equivalent to an actual conviction. No reasonable judge could hold that the Apprendi exception was satisfied by a California court, 7 years after the criminal proceedings were completed, making a guess as to what could have been proved if the 1993 prosecution of Wilson had been different.
For these reasons, the judgment of the district court is REVERSED and the case is REMANDED.
. The government argues that Wilson failed to exhaust his state remedies because he didn't present the Apprendi issue to the state court of appeal. But the state supreme court's denial of the claim on the merits is sufficient to allow Wilson to proceed. See Greene v. Lambert, 288 F.3d 1081, 1086 (9th Cir.2002) ("[E]xhaustion does not require repeated as*1215sertions if a federal claim is actually considered at least once on the merits by the highest state court.... If the Washington Supreme Court declined to apply the procedural bar that was available to it and adjudicated the claim on the merits, then the claim may proceed.”).
. The government points to a Second Circuit decision that stated that "[¡judges frequently must make factual determinations for sentencing, so it is hardly anomalous to require that they also determine the ‘who, what, when, and where' of a prior conviction.” United States v. Santiago, 268 F.3d 151, 156 (2d Cir.2001). But the court there held only that a judge may find that prior convictions arose from offenses committed on different occasions — a ministerial inquiry into dates, not into the nature of the offenses or how they occurred. Id. at 155, 156-57. Indeed, it expressly declined to reach whether the prior conviction exception "extends to all issues related to recidivism.” Id. at 156.
