OPINION
¶ 1 This opinion addresses questions regarding the application of
Blakely v. Washington,
— U.S. —,
¶ 2 The State moved for reconsideration of our decision. In the memorandum decision, we had vacated an aggravated and enhanced sentence of twelve and one-half years imprisonment for aggravated assault. 1 The sentencing court had relied upon facts in aggravation not found by the jury. We held that because the aggravating circumstances were not found by the jury, and because this failing was fundamental error, the Defendant must be resentenced.
¶ 3 The State’s motion for reconsideration of our decision advanced two arguments. The State contended that Defendant waived the Blakely error, and that any such error was harmless. The State did not dispute that the failure to submit the aggravating factors to the jury was error. We permitted the Defendant to respond. See Ariz. R.Crim. P. 31.18(b). We now withdraw our prior memorandum decision and address the issues by opinion.
I.
¶ 4 The context in which the Blakely issues arise is a conviction for aggravated assault, a class three dangerous felony. Defendant encountered the victim late at night outside of a bar. Defendant and the victim bumped into each other. The victim responded verbally, and the situation became hostile. Defendant’s friends pushed him away from the victim. Defendant stated that he was going to stab the victim. He approached the victim, restrained the victim’s right arm, and cut under his left armpit with a sharp instrument. One of the victim’s friends pushed Defendant away, and he fled the scene.
¶ 5 The victim’s artery and all nearby major nerves and veins were severed. Emergency surgery was required to restore blood flow to his arm. Many more surgeries were performed, but the victim essentially cannot use his left arm or hand, and doctors gave him a “poor prognosis.” The victim has suffered from constant pain and extensive scarring. The victim’s body cannot control the *467 swelling of the arm due to severed lymph nodes.
¶ 6 Defendant was charged with aggravated assault. A jury convicted him and found that the offense was dangerous. The court imposed an aggravated and enhanced sentence of 12.5 years of imprisonment. Defendant timely appealed. We have jurisdiction pursuant to Article 6, Section 9, of the Arizona Constitution and A.R.S. §§ 12-120.21(A)(1)(2003), 13-1031 (2001), and 13-4032 (2001).
II.
¶ 7 We first consider whether we should ignore the error because Defendant waived it. Defendant neither cited Blakely nor argued the constitutional issue when he objected to his sentence. However, the Supreme Court had not decided Blakely until after Defendant had been sentenced, and Defendant therefore could not have cited it at sentencing. 2
¶ 8 A defendant does not waive error that could not have been recognized until the defendant’s case was pending on appeal due to a change in the law.
Ranburger v. S. Pac. Tramp. Co.,
Defendant therefore did not waive the defect by failing to raise it. “[A] new rule for the conduct of criminal prosecutions is to be applied retroactively to all eases, state or federal, pending on direct review or not yet final ____”
Griffith v. Kentucky,
¶ 9 Moreover, we need not apply waiver even when a party has failed to preserve an issue. The practice of not addressing issues for the first time on appeal is merely a rule of procedure and does not confine our jurisdiction.
Town of S. Tucson v. Bd. of Supervisors of Pima Co.,
¶ 10 Even if the error were waived, we can review for fundamental error.
State v. Gendron,
¶ 11 The application of the fundamental error doctrine comports with a long line of Arizona cases that regard an illegal sentence, including a sentence that results from improper consideration of a fact to increase the sentence, as fundamental error.
E.g., State v. Thues,
¶ 12 Finally, the right to a jury trial requires an affirmative waiver that is knowing and voluntary.
See Johnson v. Zerbst,
III.
¶ 13 Because the error was not waived, we proceed to consider whether it was harmless. Failure to submit an aggravating factor to the jury is subject to review for harmless error.
State v. Ring,
¶ 14 The State contends that any error was harmless because only one aggravating factor need be properly found. Its argument is that if one such factor is present, the imposition of an aggravated sentence is for the judge’s discretion. The judge may then consider additional aggravating circumstances even if they were not found by a jury. In other words, according to the State, a single aggravating factor confers sentencing discretion upon the judge anywhere within the range of the presumptive sentence to the maximum sentence, and additional aggravating circumstances may be determined by the judge alone.
¶ 15 Recently, another panel of this Court accepted a variation of this argument.
State v. Martinez,
¶ 16 While we agree with
Martinez
that the aggravating fact of death was implicit in the jury verdict and therefore was found by the jury,
8
we disagree that a single properly found aggravating factor satisfies
Blakely
when the sentence also rests on other aggravating factors not found by the jury.
Martinez
is directly contrary to our supreme court’s decision in
Ring,
The State asserts that if the jury implicitly found one aggravating factor or the trial judge found one factor not subject to the Ring II [Ring v. Arizona,536 U.S. 584 ,122 S.Ct. 2428 ,153 L.Ed.2d 556 (2002)] analysis, we can uphold the capital sentence imposed by the trial judge as harmless error. The argument relies upon the fact that Arizona’s superseded sentencing scheme rendered a defendant “death eligible” if one aggravating factor existed____ Nothing in Ring II, the State argues, prevents a trial judge from finding the second and succeeding aggravating factors, as well as finding mitigating factors and balancing them against the aggravator.
¶ 17 The State’s argument was squarely rejected by the supreme court. Although defendant becomes “eligible” for an aggravated sentence upon the finding of a single aggravating factor,
“Ring II
should not be read that narrowly ...
Ring II
requires a jury to consider
all
aggravating factors urged by the state and not either exempt from
Ring II,
implicit in the jury’s verdict, or otherwise established beyond a reasonable doubt.”
Id.
at 562, ¶ 88,
¶ 18
Martinez
errs in failing to follow the supreme court’s decision in
Ring. Martinez
acknowledges
Ring,
but asserts that it need not be adhered to because it is a capital punishment case, and non-capital cases are different.
Martinez,
¶ 19 In fact, the very authority to which
Martinez
points,
see id.,
shows that the sentencing schemes are functionally similar in their use of aggravating and mitigating factors.
See, e.g.,
A.R.S. § 13-703(E), (F), (G) (Supp.2004) (capital sentencing statute adopting the same aggravating and mitigating factors of the general sentencing statute, A.R.S. § 13-702 (Supp.2004)).
State v. Beasley,
¶ 20
Martinez
also attempts to marshall federal authority in support, but it misconstrues what the United States Supreme Court has said. For example,
Martinez
relies on
Harris v. United States,
¶ 21 Our review of the decisions of the United States Supreme Court on point yields a clear direction that not just one, but all facts that can be used to increase punishment must be found by the jury. In
Apprendi,
the Court said: “Other than the fact of a prior conviction,
any fact
that increases the penalty for a crime beyond the prescribed statuto
*471
ry maximum must be submitted to a jury, and proved beyond a reasonable doubt.”
¶ 22 Lest there be any doubt,
Blakely
also reminded us “that the ‘truth of
every
accusation’ against a defendant” should be decided by a jury.
Id.
at 2536 (emphasis added) (quoting 4 W. Blackstone, Commentaries on the Laws of England 343 (1769)). In
Blakely,
too, the court said that “every defendant has the right to insist that the prosecutor prove to a jury
all
facts legally essential to the punishment.”
Id.
at 2543 (original emphasis omitted; new emphasis added). “
‘[E]very
fact which is legally essential to the punishment’ must be charged in the indictment and proved to a jury.”
Id.
at 2536 n. 5 (emphasis added) (quoting 1 J. Bishop, Criminal Procedure, at 50-56 (2d ed. 1872)). And again, the Court made the scope of its holding clear in discussing its prior opinion in
Apprendi,
which “carries out this [constitutional] design by ensuring that the judge’s authority to sentence derives
wholly
from the jury’s verdict.”
Blakely,
¶ 23 The reasoning of
Martinez
also conflicts with the constitutional underpinning of the Supreme Court’s opinions.
Apprendi
and
Blakely
rest on two principles: the constitutional requirement that the jury decide beyond a reasonable doubt all elements of the offense, and the absence of any real “distinction between ‘elements’ and ‘sentencing factors.’ ”
Apprendi
*472 ¶ 24 The source of the error in Martinez is that it conflicts with the legislatively mandated sentencing system. Martinez rests upon this proposition: Because a single aggravating factor can support an aggravated sentence, an aggravated sentence must be affirmed if a single aggravating factor was properly found, even though other aggravating factors used to increase the sentence were erroneously found.
¶ 25 The premise on which Martinez relies is incorrect, as our supreme court indicated in Ring. Although a single aggravating circumstance can be enough to make a defendant eligible for increased punishment, the actual length of sentence is to be imposed only after weighing all the aggravating and mitigating circumstances. In other words, the aggravating factor justifies a theoretical sentence somewhere in the range between the presumptive and maximum punishments. However, a particular sentence cannot be imposed without regard to all of the aggravating and mitigating circumstances. Put another way, a single aggravating factor exposes the defendant to a greater sentence, but only consideration of all of the aggravating circumstances actually determines the punishment. 11 For example, a given sentence may well be lengthier if several, as opposed to only one, aggravating circumstances are considered. And any of the aggravating circumstances can incrementally increase the sentence beyond the punishment that would have been imposed without considering that circumstance. Thus, all of the aggravating circumstances must be considered.
¶ 26 The existence of a single aggravating circumstance also does not necessarily subject defendant to an aggravated sentence. If mitigating circumstances are also present, the court may impose a presumptive or mitigated sentence. It is only when “the court finds aggravating circumstances and does not find any mitigating circumstances [that] the court shall impose an aggravated sentence.” A.R.S. § 13-702(D)(5). Thus, under the statute, a single aggravating factor does not always render a defendant eligible for an aggravated sentence. When mitigating circumstances are also present, it is for the discretion of the sentencing judge to decide whether punishment greater than the presumptive is warranted. When the judge relied on several aggravators, and only one was proper, we may be unable to discern whether the judge would have regarded the single proper factor enough to render defendant eligible for the greater punishment. That discretion is the sentencing judge’s province, not ours.
¶ 27 With its one-factor-is-enough approach, Martinez purports to recognize the sentencing judge’s authority to sentence upon a single factor. But the courts lack such authority. The Arizona Legislature has prescribed the sentencing system that judges must follow, and it has required that all sentencing factors be considered.
¶ 28 Under the statutory sentencing scheme, one factor does not a sentence make. A sentence beyond the presumptive can be determined only after considering all of the *473 statutorily enumerated aggravating and mitigating factors, and after giving suitable weight to each. The Legislature directed the judicial branch as follows: “The court shall consider” the enumerated circumstances. A.R.S. § 13-702(C), (D). “Any reduction or increase [from the presumptive sentences of A.R.S. § 13-701 (2001) ] shall be based on the aggravating and mitigating circum-stances____"A.R.S. § 13-702(A).
¶ 29 The sentencing laws thus forbid the very thing that
Martinez
approves: consideration of a single factor in isolation. The Legislature requires not only that the judge consider all the statutorily relevant circumstances, but also that the sentencing judge weigh and balance them. “In determining what sentence to impose, the court shall take into account the amount of aggravating circumstances and whether the amount of mitigating circumstances is sufficiently substantial to call for the lesser term.” A.R.S. § 13-702(D). “The trial court must weigh all aggravating and mitigating circumstances in passing sentence.”
State v. Bocharski,
¶ 30 We therefore cannot automatically uphold sentences based on the presence of a single aggravating factor when the sentencing judge relied on others not properly found by a jury. As the Supreme Court of Arizona has determined,
“all
aggravating factors” in imposing a sentence must be found by the jury.
Ring,
¶ 31 A simple hypothetical clarifies the application of
Blakely
to Arizona’s sentencing system. Let us suppose that the legislatively prescribed presumptive sentence, i.e., the sentence authorized by the jury verdict alone without aggravating factors, is five years, and the maximum sentence is ten years. A single aggravating factor is found and the sentencing judge imposes a sentence of six years. If a second aggravating factor had been found, our hypothetical judge would have imposed a sentence of seven years. The additional aggravating circumstance is clearly a fact that increases the punishment beyond that authorized by the jury verdict alone, and is therefore subject to the requirement of
Blakely
that the fact be proved to a jury beyond a reasonable doubt. As the Court said in
Apprendi,
“the relevant inquiry is one not of form but of effect — does the required finding expose the defendant to a greater punishment than that authorized by the jury’s guilty verdict?”
¶ 32 Another hypothetical illustrates why Blakely’s mandate cannot be avoided by finding a single aggravator. Assume that both multiple aggravating and mitigating circumstances are present. The sentencing judge weighs all circumstances. Relying on the aggregation of aggravating circumstances, the judge imposes an aggravated sentence. Had only one of the aggravating factors been present, the judge would have balanced the factors differently and not have imposed an aggravated punishment at all. Any aggravating factor thus can, but not necessarily will, lead to an aggravated sentence, and therefore all such factors must be decided by the jury.
¶ 33 Nor can we discern any wisdom in inviting disparate treatment of defendants as Martinez necessarily does. For example, Martinez proposes that a defendant who has committed a prior felony — a fact that need not be submitted to the jury — but is alleged to be subject to increased punishment due to other circumstances would not be entitled to a jury trial. However, under Martinez a *474 defendant, charged with the very same crime and all of the same aggravating circumstances except that he has no prior convictions, would be entitled to a jury trial of at least one of the aggravating factors. Thus, one defendant would be entitled to a jury trial and the other would not, even though the fact issue is identical.
¶ 34 We cannot rely on a single aggravating factor. We therefore must review all of the aggravating circumstances to determine whether the error in failing to submit them to the jury was harmless.
¶ 35 The judge relied on several factors, both aggravating and mitigating. The record contains uncontroverted evidence of the first aggravating factor, extraordinary severity of the harm to the victim. The superior court stated:
[The victim] was hospitalized for weeks. He nearly died. He’s undergone ... at least 15 surgeries already. His pain is enormous. His suffering is enormous, and it will continue for the rest of his life. His left arm is paralyzed. He continues physical therapy. He came very close to dying in this case.
The sentencing judge relied on the victim’s extraordinary harm and suffering. Because this harm is different from and greater than the “serious physical injury” element of the offense, it is a proper sentencing factor.
See
A.R.S. § 13-702(C)(9);
State v. Germain,
¶ 36 The judge also relied on an additional aggravating factor not submitted to the jury: the viciousness of Defendant’s actions. See A.R.S. § 13-702(C)(5). Whether the offense was committed in an “[especially heinous, cruel or depraved manner” as required by § 13-702(C)(5) was not clear beyond a reasonable doubt. While the offense was violent and resulted in traumatic and permanent injury, aggravated assaults inherently involve either a deadly weapon or serious physical injury. In particular, the sentencing judge relied on a single fact to move this case into the realm of the especially vicious: “[T]his is not just a stabbing. This was a sawing action where the tendons and muscles ... were cut to the bone.” Yet the record permits different inferences as to whether the injury was inflicted by a method that constitutes special cruelty or depravity. 12 This fact cannot be said to have been proved to the extent that any reasonable jury would agree with it beyond any reasonable doubt. It therefore should have been submitted to the jury for decision.
¶ 37 The final aggravating factor was the use of a dangerous instrument or deadly weapon. See A.R.S. § 13-702(C)(2). The assault offense was charged as aggravated assault based on the use of a weapon or dangerous instrument. See A.R.S. § 13-1204(A)(2) (Supp.2004). The sentence was also enhanced as a dangerous offense, see A.R.S. § 13-604(P), although it is not clear whether the dangerousness was found in the use of a weapon or the seriousness of the injury because neither the indictment nor the jury instruction specified which was the basis of the dangerous nature of the offense.
¶ 38 Employing the fact of a deadly weapon to prove an offense, then to aggravate a sentence, and finally to enhance *475 a sentence, is problematic. Under A.R.S. § 13-702(C), the court can consider the following as aggravating factors when imposing a sentence:
1. Infliction or threatened infliction of serious physical injury, except if this circumstance is an essential element of the offense of conviction or has been utilized to enhance the range of punishment under § 13-604.
2. Use, threatened use or possession of a deadly weapon or dangerous instrument during the commission of the crime, except if this circumstance is an essential element of the offense of conviction or has been utilized to enhance the range of punishment under § 13-604.
Thus, the use of a weapon and the seriousness of the injury cannot be “double-counted” by using them to prove guilt and then to aggravate the sentence, or by using them to enhance the sentence and then to aggravate it. 13
¶ 39 Relying on the use of the weapon to aggravate the sentence twice counted this fact because it was also an element of the offense. The indictment specifically alleged that the assault constituted aggravated assault because of the use of a dangerous instrument. Pointedly, the indictment did not allege serious physical injury to elevate the offense from simple assault to aggravated assault. Accordingly, the court’s reliance on this factor violated § 13-702(C)(2).
¶ 40 The judge thus relied on three aggravating factors: extraordinary harm, viciousness, and weapon. The extraordinary harm is indisputable and therefore the failure to submit this fact to the jury was, standing alone, harmless. The viciousness was debatable and should have been decided by the jury. The use of a weapon was a factor that, because it was an element of the offense, cannot be considered in aggravation. The judge also found several mitigating factors, including the Defendant’s age, remorse, lack of a prior felony record, difficult childhood, and the role of alcohol. See A.R.S. § 13-702(D) (mitigating factors). As statutorily required, the judge balanced these mitigating circumstances against the aggravating factors. He found that the aggravating factors outweighed the mitigating.
¶ 41 When a trial court relies on an improper factor, and we cannot be certain that it would have imposed the same sentence absent that factor, we must remand for resentencing. A sentencing error involving the improper consideration of aggravating factors is harmless only if we can be certain that, absent the error, the court would have reached the same result.
Hardwick,
*476
¶ 42 When it is “unclear whether the judge would have imposed the same sentences absent the inappropriate factor, the case must be remanded for resentencing.”
Alvarez,
¶ 43 Accordingly, we have granted the motion for reconsideration and withdrawn our prior memorandum decision. We now vacate the sentence and remand for resentencing.
Notes
. The presumptive term for aggravated assault, enhanced as a dangerous felony, is 7.5 years. See Arizona Revised Statutes ("A.R.S.”) section 13-604(I) (Supp.2004). The jury found that the offense was dangerous. This finding resulted in an "enhanced” sentence, i.e., an increase of the sentencing range.
. Moreover, the State does not suggest that Defendant waived the arguments at the core of his appeal: He contests the evidentiary and legal support for the aggravating circumstances employed to increase his sentence. Thus, the propriety of increasing the sentence by employing aggravating factors remains the essence of this appeal. Blakely provides Defendant new support for his argument: No longer is the aggravated sentence merely vulnerable to attack under Arizona law, but it is now questionable as a matter of federal constitutional law.
.
See State v. Alvarez,
. We express no opinion as to whether a defendant who has waived his right to a jury trial generally need specifically waive his right to a jury trial of sentencing factors. A defendant who has not waived his right to a jury, however, has not waived the issue. As far as we can determine, all courts that have considered this question agree that a defendant who exercised his right to a jury trial of his guilt, and who has not expressly waived his right to a jury trial of sentencing factors, has not waived his
Blakely
challenge because he has not waived a juiy.
See, e.g., People v. Vu,
.
Martinez
must be distinguished from cases in which an aggravated sentence was not imposed, a situation that does not implicate
Blakely. See Miranda-Cabrera,
. Whether the reasoning leads to the supposed absence of error or the alleged harmlessness of the error, we disagree with it.
. The existence of a prior conviction need not be found by a jury to be used as an aggravating factor.
Apprendi v. New Jersey,
.
See State v. Gatliff,
. Not even the dissenting justices harbored doubt on this point. The jury must decide "every fact” relevant to the determination of sentence....”
Apprendi,
. Although the State may be able to choose which aggravating circumstances it will attempt to prove, it cannot, having made that decision, choose which among them will be presented to the jury and which to the judge. Nor should vindication of the right be left to chance or to the prosecutor’s inventiveness, or subject to an attempt to remedy prosecutorial sloppiness. If, for example, the State alleged an aggravating cir *472 cumstance but forgot to introduce supporting evidence at the jury trial, would the State then have a second chance to prove the factor to a judge so long as one factor had been presented and proved to the jury? Can the State circumvent the defendant's right to a jury trial beyond reasonable doubt by choosing a single factor? For example, the prosecutor might present for jury determination by a reasonable doubt a sole aggravating factor that is strongly supported by the evidence but only weakly aggravating; i.e., it might either be insufficient standing alone to justify an aggravated sentence in the face of mitigating factors, or be enough to increase the length of sentence only slightly beyond the presumptive. Could the prosecutor then present to a judge other factors which argue more strongly for increased punishment but are supported by less persuasive evidence? Such an approach would subject the defendant's constitutional right to the mercy of the State.
. The language of
Martinez
itself illustrates the difference: A single aggravating factor makes defendant "eligible” for an aggravated sentence, and a single factor affects the "sentencing range.”
. The physician’s testimony on which the court relied indicated that the injury was inflicted by a sawing movement that was forceful but brief in duration. The victim also described a sawing motion but not of great duration. The record thus reflects the basic mechanics of the infliction of injury, but does not show beyond reasonable doubt that the manner was extraordinarily cruel or depraved.
See Tucker,
. The sentencing court's reliance on the extraordinary harm to the victim as the other aggravating factor did not violate this rule. The court did not find merely that the victim suffered a serious physical injury, but that he suffered from additional, extraordinary harm. "The physical, emotional and financial harm caused to the victim” is treated as a separate factor from the infliction of serious physical injury under the sentencing statute. A.R.S. § 13-702(C)(9). Moreover, we have held that "[w]here the degree of the defendant’s misconduct rises to a level beyond that which is merely necessary to establish an element of the underlying crime, the trial court may consider such conduct as an aggravating factor."
Germain,
. The sentencing judge explicitly found that each of the aggravating factors alone would outweigh the mitigating factors, but that establishes only that the judge would not have imposed a mitigated sentence, not that the sentence would be aggravated or aggravated to the same extent if only one of the aggravating circumstances were present. See A.R.S. § 13-702(D)(5). In other words, that statement does not inform us that the same sentence would have been imposed with fewer aggravating circumstances.
