JUSTICE STEVENS delivered the opinion of the Court in part, concluding that the Sixth Amendment as construed in Blakely applies to the Federal Sentencing Guidelines. Pp. 230-244.

(a) In addressing Washington State's determinate sentencing scheme, the Blakely Court found that Jones v. United States, 526 U. S. 227; Apprendi v. New Jersey, 530 U. S. 466; and Ring v. Arizona, 536 U. S. 584, made clear "that the `statutory maximum' for Apprendi purposes is the maximum sentence a judge may impose solely on the basis of the facts reflected in the jury verdict or admitted by the defendant." 542 U. S., at 303. As Blakely's dissenting opinions recognized, there is no constitutionally significant distinction between the Guidelines and the Washington procedure at issue in that case. This conclusion rests on the premise, common to both systems, that the relevant sentencing rules are mandatory and impose binding requirements on all sentencing judges. Were the Guidelines merely advisory—recommending, but not requiring, the selection of particular sentences in response to differing sets of facts—their use would not implicate the Sixth Amendment. However, that is not the case. Title 18 U. S. C. A. § 3553(b) directs that a court "shall impose a sentence of the kind, and within the range" established by the Guidelines, subject to departures in specific, limited cases. Because they are binding on all judges, this Court has consistently held that the Guidelines have the force and effect of laws. Further, the availability of a departure where the judge "finds ... an aggravating or mitigating circumstance of a kind, or to a degree, not adequately taken into consideration by the Sentencing Commission in formulating the guidelines that should result in a sentence different from that described," § 3553(b)(1), does not avoid the constitutional issue. Departures are unavailable in most cases because the Commission will have adequately taken all relevant factors into account, and no departure will be legally permissible. In those instances, the judge is legally bound to impose a sentence within the Guidelines range. Booker's case illustrates this point. The jury found him guilty of possessing at least 50 grams of crack cocaine, based on evidence that he had 92.5 grams. Under those facts, the Guidelines required a possible 210-to-262-month sentence. To reach Booker's actual sentence — which was almost 10 years longer — the judge found that he possessed an additional 566 grams of crack. Although, the jury never heard any such evidence, the judge found it to be true by a preponderance of the evidence. Thus, as in Blakely, "the jury's verdict alone does not authorize the sentence. The judge acquires that authority only upon finding some additional fact." 542 U. S., at 305. Finally, because there were no factors the Sentencing Commission failed to adequately consider, the judge was required to impose a sentence within the higher Guidelines range. Pp. 230-237.

(b) The Government's arguments for its position that Blakely's reasoning should not be applied to the Federal Sentencing Guidelines are unpersuasive. The fact that the Guidelines are promulgated by the Sentencing Commission, rather than Congress, is constitutionally irrelevant. The Court has not previously considered the question, but the same Sixth Amendment principles apply to the Sentencing Guidelines. Further, the Court's pre-Apprendi cases considering the Guidelines are inapplicable, as they did not consider the application of Apprendi to the Sentencing Guidelines. Finally, separation of powers concerns are not present here, and were rejected in Mistretta v. United States, 488 U. S. 361. In Mistretta the Court concluded that even though the Commission performed political rather than adjudicatory functions, Congress did not exceed constitutional limitations in creating the Commission. Id., at 388, 393. That conclusion remains true regardless of whether the facts relevant to sentencing are labeled "sentencing factors" or "elements" of crimes. Pp. 237-244.

JUSTICE BREYER delivered the opinion of the Court in part, concluding that 18 U. S. C. A. § 3553(b)(1), which makes the Federal Sentencing Guidelines mandatory, is incompatible with today's Sixth Amendment "jury trial" holding and therefore must be severed and excised from the Sentencing Reform Act of 1984 (Act). Section 3742(e), which depends upon the Guidelines' mandatory nature, also must be severed and excised. So modified, the Act makes the Guidelines effectively advisory, requiring a sentencing court to consider Guidelines ranges, see § 3553(a)(4), but permitting it to tailor the sentence in light of other statutory concerns, see § 3553(a). Pp. 246-268.

(a) Answering the remedial question requires a determination of what "Congress would have intended" in light of the Court's constitutional holding. E. g., Denver Area Ed. Telecommunications Consortium, Inc. v. FCC, 518 U. S. 727, 767. Here, the Court must decide which of two approaches is the more compatible with Congress' intent as embodied in the Act: (1) retaining the Act (and the Guidelines) as written, with today's Sixth Amendment requirement engrafted onto it; or (2) eliminating some of the Act's provisions. Evaluation of the constitutional requirement's consequences in light of the Act's language, history, and basic purposes demonstrates that the requirement is not compatible with the Act as written and that some severance (and excision) is necessary. Congress would likely have preferred the total invalidation of the Act to an Act with the constitutional requirement engrafted onto it, but would likely have preferred the excision of the Act's mandatory language to the invalidation of the entire Act. Pp. 246-249.

(b) Several considerations demonstrate that adding the Court's constitutional requirement onto the Act as currently written would so transform the statutory scheme that Congress likely would not have intended the Act as so modified to stand. First, references to "[t]he court" in § 3553(a)(1) — which requires "[t]he court" when sentencing to consider "the nature and circumstances of the offense and the history and characteristics of the defendant" — and references to "the judge" in the Act's history must be read in context to mean "the judge without the jury," not "the judge working together with the jury." That is made clear by § 3661, which removes typical "jury trial" limitations on "the information" concerning the offender that the sentencing "court ... may receive." Second, Congress' basic statutory goal of diminishing sentencing disparity depends for its success upon judicial efforts to determine, and to base punishment upon, the real conduct underlying the crime of conviction. In looking to real conduct, federal sentencing judges have long relied upon a probation officer's presentence report, which is often unavailable until after the trial. To engraft the Court's constitutional requirement onto the Act would destroy the system by preventing a sentencing judge from relying upon a presentence report for relevant factual information uncovered after the trial. Third, the Act, read to include today's constitutional requirement, would create a system far more complex than Congress could have intended, thereby greatly complicating the tasks of the prosecution, defense, judge, and jury. Fourth, plea bargaining would not significantly diminish the consequences of the Court's constitutional holding for the operation of the Guidelines, but would make matters worse, leading to sentences that gave greater weight not to real conduct, but rather to counsel's skill, the prosecutor's policies, the caseload, and other factors that vary from place to place, defendant to defendant, and crime to crime. Fifth, Congress would not have enacted sentencing statutes that make it more difficult to adjust sentences upward than to adjust them downward, yet that is what the engrafted system would create. For all these reasons, the Act cannot remain valid in its entirety. Severance and excision are necessary. Pp. 249-258.

(c) The entire Act need not be invalidated, since most of it is perfectly valid. In order not to "invalidat[e] more of the statute than is necessary," Regan v. Time, Inc., 468 U. S. 641, 652, the Court must retain those portions of the Act that are (1) constitutionally valid, ibid., (2) capable of "functioning independently," Alaska Airlines, Inc. v. Brock, 480 U. S. 678, 684, and (3) consistent with Congress' basic objectives in enacting the statute, Regan, supra, at 653. Application of these criteria demonstrates that only § 3553(b)(1), which requires sentencing courts to impose a sentence within the applicable Guidelines range (absent circumstances justifying a departure), and § 3742(e), which provides for de novo review on appeal of departures, must be severed and excised. With these two sections severed (and statutory cross-references to the two sections consequently invalidated), the rest of the Act satisfies the Court's constitutional requirement and falls outside the scope of Apprendi v. New Jersey, 530 U. S. 466. The Act still requires judges to take account of the Guidelines together with other sentencing goals, see § 3553(a)(4); to consider the Guidelines "sentencing range established for ... the applicable category of offense committed by the applicable category of defendant," pertinent Sentencing Commission policy statements, and the need to avoid unwarranted sentencing disparities and to restitute victims, §§ 3553(a)(1), (3)-(7); and to impose sentences that reflect the seriousness of the offense, promote respect for the law, provide just punishment, afford adequate deterrence, protect the public, and effectively provide the defendant with needed training and medical care, § 3553(a)(2). Moreover, despite § 3553(b)(1)'s absence, the Act continues to provide for appeals from sentencing decisions (irrespective of whether the trial judge sentences within or outside the Guidelines range). See §§ 3742(a) and (b). Excision of § 3742(e), which sets forth appellate review standards, does not pose a critical problem. Appropriate review standards may be inferred from related statutory language, the statute's structure, and the "`sound administration of justice.'" Pierce v. Underwood, 487 U. S. 552, 559-560. Here, these factors and the past two decades of appellate practice in cases involving departures from the Guidelines imply a familiar and practical standard of review: review for "unreasonable[ness]." See, e. g., 18 U. S. C. § 3742(e)(3) (1994 ed.). Finally, the Act without its mandatory provision and related language remains consistent with Congress' intent to avoid "unwarranted sentencing disparities ... [and] maintai[n] sufficient flexibility to permit individualized sentences when warranted," 28 U. S. C. § 991(b)(1)(B), in that the Sentencing Commission remains in place to perform its statutory duties, see § 994, the district courts must consult the Guidelines and take them into account when sentencing, see 18 U. S. C. § 3553(a)(4), and the courts of appeals review sentencing decisions for unreasonableness. Thus, it is more consistent with Congress' likely intent (1) to preserve the Act's important pre-existing elements while severing and excising §§ 3553(b) and 3742(e) than (2) to maintain all of the Act's provisions and engraft today's constitutional requirement onto the statutory scheme. Pp. 258-265.

(d) Other possible remedies—including, e. g., the parties' proposals that the Guidelines remain binding in cases other than those in which the Constitution prohibits judicial factfinding and that the Act's provisions requiring such factfinding at sentencing be excised—are rejected. Pp. 265-267.

(e) On remand in respondent Booker's case, the District Court should impose a sentence in accordance with today's opinions, and, if the sentence comes before the Seventh Circuit for review, that court should apply the review standards set forth in this Court's remedial opinion. In respondent Fanfan's case, the Government (and Fanfan should he so choose) may seek resentencing under the system set forth in today's opinions. As these dispositions indicate, today's Sixth Amendment holding and the Court's remedial interpretation of the Sentencing Act must be applied to all cases on direct review. See, e.g., Griffith v. Kentucky, 479 U. S. 314, 328. That does not mean that every sentence will give rise to a Sixth Amendment violation or that every appeal will lead to a new sentencing hearing. That is because reviewing courts are expected to apply ordinary prudential doctrines, determining, e.g., whether the issue was raised below and whether it fails the "plain-error" test. It is also because, in cases not involving a Sixth Amendment violation, whether resentencing is warranted or whether it will instead be sufficient to review a sentence for reasonableness may depend upon application of the harmless-error doctrine. Pp. 267-268.

T. Christopher Kelly argued the cause for respondent in No. 04-104. With him on the brief was Dean A. Strang. Rosemary Curran Scapicchio argued the cause for respondent in No. 04-105. With her on the brief were Carter G. Phillips, Jeffrey T. Green, Eric A. Shumsky, and Martin G. Weinberg.^†

JUSTICE STEVENS delivered the opinion of the Court in part.*

The question presented in each of these cases is whether an application of the Federal Sentencing Guidelines violated the Sixth Amendment. In each case, the courts below held that binding rules set forth in the Guidelines limited the severity of the sentence that the judge could lawfully impose on the defendant based on the facts found by the jury at his trial. In both cases the courts rejected, on the basis of our decision in Blakely v. Washington, 542 U. S. 296 (2004), the Government's recommended application of the Sentencing Guidelines because the proposed sentences were based on additional facts that the sentencing judge found by a preponderance of the evidence. We hold that both courts correctly concluded that the Sixth Amendment as construed in Blakely does apply to the Sentencing Guidelines. In a separate opinion authored by JUSTICE BREYER, the Court concludes that in light of this holding, two provisions of the Sentencing Reform Act of 1984 (SRA) that have the effect of making the Guidelines mandatory must be invalidated in order to allow the statute to operate in a manner consistent with congressional intent.

* Respondent Booker was charged with possession with intent to distribute at least 50 grams of cocaine base (crack). Having heard evidence that he had 92.5 grams in his duffel bag, the jury found him guilty of violating 21 U. S. C. § 841(a)(1). That statute prescribes a minimum sentence of 10 years in prison and a maximum sentence of life for that offense. § 841(b)(1)(A)(iii).

Based upon Booker's criminal history and the quantity of drugs found by the jury, the Sentencing Guidelines required the District Court Judge to select a "base" sentence of not less than 210 nor more than 262 months in prison. See United States Sentencing Commission, Guidelines Manual §§ 2D1.1(c)(4), 4A1.1 (Nov. 2003) (USSG). The judge, however, held a post-trial sentencing proceeding and concluded by a preponderance of the evidence that Booker had possessed an additional 566 grams of crack and that he was guilty of obstructing justice. Those findings mandated that the judge select a sentence between 360 months and life imprisonment; the judge imposed a sentence at the low end of the range. Thus, instead of the sentence of 21 years and 10 months that the judge could have imposed on the basis of the facts proved to the jury beyond a reasonable doubt, Booker received a 30-year sentence.

Over the dissent of Judge Easterbrook, the Court of Appeals for the Seventh Circuit held that this application of the Sentencing Guidelines conflicted with our holding in Apprendi v. New Jersey, 530 U. S. 466, 490 (2000), that "[o]ther than the fact of a prior conviction, any fact that increases the penalty for a crime beyond the prescribed statutory maximum must be submitted to a jury, and proved beyond a reasonable doubt." 375 F. 3d 508, 510 (2004). The majority relied on our holding in Blakely, 542 U. S. 296, that "the `statutory maximum' for Apprendi purposes is the maximum sentence a judge may impose solely on the basis of the facts reflected in the jury verdict or admitted by the defendant." Id., at 303. The court held that the sentence violated the Sixth Amendment, and remanded with instructions to the District Court either to sentence respondent within the sentencing range supported by the jury's findings or to hold a separate sentencing hearing before a jury.

Respondent Fanfan was charged with conspiracy to distribute and to possess with intent to distribute at least 500 grams of cocaine in violation of 21 U. S. C. §§ 846, 841(a)(1), and 841(b)(1)(B)(ii). He was convicted by the jury after it answered "Yes" to the question "Was the amount of cocaine 500 or more grams?" App. C to Pet. for Cert. in No. 04-105, p. 15a. Under the Guidelines, without additional findings of fact, the maximum sentence authorized by the jury verdict was imprisonment for 78 months.

A few days after our decision in Blakely, the trial judge conducted a sentencing hearing at which he found additional facts that, under the Guidelines, would have authorized a sentence in the 188-to-235-month range. Specifically, he found that respondent Fanfan was responsible for 2.5 kilograms of cocaine powder, and 261.6 grams of crack. He also concluded that respondent had been an organizer, leader, manager, or supervisor in the criminal activity. Both findings were made by a preponderance of the evidence. Under the Guidelines, these additional findings would have required an enhanced sentence of 15 or 16 years instead of the 5 or 6 years authorized by the jury verdict alone. Relying not only on the majority opinion in Blakely, but also on the categorical statements in the dissenting opinions and in the Solicitor General's brief in Blakely, see App. A to Pet. for Cert. in No. 04-105, pp. 6a-7a, the judge concluded that he could not follow the particular provisions of the Sentencing Guidelines "which involve drug quantity and role enhancement," id., at 11a. Expressly refusing to make "any blanket decision about the federal guidelines," he followed the provisions of the Guidelines that did not implicate the Sixth Amendment by imposing a sentence on respondent "based solely upon the jury verdict in this case." Ibid.

Following the denial of its motion to correct the sentence in Fanfan's case, the Government filed a notice of appeal in the Court of Appeals for the First Circuit, and a petition in this Court for a writ of certiorari before judgment. Because of the importance of the questions presented, we granted that petition, 542 U. S. 956 (2004), as well as a similar petition filed by the Government in Booker's case, ibid. In both petitions, the Government asks us to determine whether our Apprendi line of cases applies to the Sentencing Guidelines, and if so, what portions of the Guidelines remain in effect.1

In this opinion, we explain why we agree with the lower courts' answer to the first question. In a separate opinion for the Court, JUSTICE BREYER explains the Court's answer to the second question.

It has been settled throughout our history that the Constitution protects every criminal defendant "against conviction except upon proof beyond a reasonable doubt of every fact necessary to constitute the crime with which he is charged." In re Winship, 397 U. S. 358, 364 (1970). It is equally clear that the "Constitution gives a criminal defendant the right to demand that a jury find him guilty of all the elements of the crime with which he is charged." United States v. Gaudin, 515 U. S. 506, 511 (1995). These basic precepts, firmly rooted in the common law, have provided the basis for recent decisions interpreting modern criminal statutes and sentencing procedures.

In Jones v. United States, 526 U. S. 227, 230 (1999), we considered the federal carjacking statute, which provides three different maximum sentences depending on the extent of harm to the victim: 15 years in jail if there was no serious injury to a victim, 25 years if there was "serious bodily injury," and life in prison if death resulted. 18 U. S. C. § 2119 (1988 ed., Supp. V). In spite of the fact that the statute "at first glance has a look to it suggesting [that the provisions relating to the extent of harm to the victim] are only sentencing provisions," 526 U. S., at 232, we concluded that the harm to the victim was an element of the crime. That conclusion was supported by the statutory text and structure, and was influenced by our desire to avoid the constitutional issues implicated by a contrary holding, which would have reduced the jury's role "to the relative importance of low-level gate-keeping." Id., at 244. Foreshadowing the result we reach today, we noted that our holding was consistent with a "rule requiring jury determination of facts that raise a sentencing ceiling" in state and federal sentencing guidelines systems. Id., at 251-252, n. 11.

In Apprendi v. New Jersey, 530 U. S. 466 (2000), the defendant pleaded guilty to second-degree possession of a firearm for an unlawful purpose, which carried a prison term of 5-to-10 years. Thereafter, the trial court found that his conduct had violated New Jersey's "hate crime" law because it was racially motivated, and imposed a 12-year sentence. This Court set aside the enhanced sentence. We held: "Other than the fact of a prior conviction, any fact that increases the penalty for a crime beyond the prescribed statutory maximum must be submitted to a jury, and proved beyond a reasonable doubt." Id., at 490.

The fact that New Jersey labeled the hate crime a "sentence enhancement" rather than a separate criminal act was irrelevant for constitutional purposes. Id., at 478. As a matter of simple justice, it seemed obvious that the procedural safeguards designed to protect Apprendi from punishment for the possession of a firearm should apply equally to his violation of the hate crime statute. Merely using the label "sentence enhancement" to describe the latter did not provide a principled basis for treating the two crimes differently. Id., at 476.

In Ring v. Arizona, 536 U. S. 584 (2002), we reaffirmed our conclusion that the characterization of critical facts is constitutionally irrelevant. There, we held that it was impermissible for "the trial judge, sitting alone" to determine the presence or absence of the aggravating factors required by Arizona law for imposition of the death penalty. Id., at 588-589. "If a State makes an increase in a defendant's authorized punishment contingent on the finding of a fact, that fact—no matter how the State labels it—must be found by a jury beyond a reasonable doubt." Id., at 602. Our opinion made it clear that ultimately, while the procedural error in Ring's case might have been harmless because the necessary finding was implicit in the jury's guilty verdict, id., at 609, n. 7, "the characterization of a fact or circumstance as an `element' or a `sentencing factor' is not determinative of the question `who decides,' judge or jury," id., at 605.

In Blakely v. Washington, 542 U. S. 296 (2004), we dealt with a determinate sentencing scheme similar to the Federal Sentencing Guidelines. There the defendant pleaded guilty to kidnaping, a class B felony punishable by a term of not more than 10 years. Other provisions of Washington law, comparable to the Federal Sentencing Guidelines, mandated a "standard" sentence of 49-to-53 months, unless the judge found aggravating facts justifying an exceptional sentence. Although the prosecutor recommended a sentence in the standard range, the judge found that the defendant had acted with "`deliberate cruelty'" and sentenced him to 90 months. Id., at 300.

For reasons explained in Jones, Apprendi, and Ring, the requirements of the Sixth Amendment were clear. The application of Washington's sentencing scheme violated the defendant's right to have the jury find the existence of "`any particular fact'" that the law makes essential to his punishment. 542 U. S., at 301. That right is implicated whenever a judge seeks to impose a sentence that is not solely based on "facts reflected in the jury verdict or admitted by the defendant." Id., at 303 (emphasis deleted). We rejected the State's argument that the jury verdict was sufficient to authorize a sentence within the general 10-year sentence for class B felonies, noting that under Washington law, the judge was required to find additional facts in order to impose the greater 90-month sentence. Our precedents, we explained, make clear "that the `statutory maximum' for Apprendi purposes is the maximum sentence a judge may impose solely on the basis of the facts reflected in the jury verdict or admitted by the defendant." Ibid. (emphasis in original). The determination that the defendant acted with deliberate cruelty, like the determination in Apprendi that the defendant acted with racial malice, increased the sentence that the defendant could have otherwise received. Since this fact was found by a judge using a preponderance of the evidence standard, the sentence violated Blakely's Sixth Amendment rights.

As the dissenting opinions in Blakely recognized, there is no distinction of constitutional significance between the Federal Sentencing Guidelines and the Washington procedures at issue in that case. See, e. g., 542 U. S., at 325 (opinion of O'CONNOR, J.) ("The structure of the Federal Guidelines likewise does not, as the Government half-heartedly suggests, provide any grounds for distinction. . . . If anything, the structural differences that do exist make the Federal Guidelines more vulnerable to attack"). This conclusion rests on the premise, common to both systems, that the relevant sentencing rules are mandatory and impose binding requirements on all sentencing judges.

If the Guidelines as currently written could be read as merely advisory provisions that recommended, rather than required, the selection of particular sentences in response to differing sets of facts, their use would not implicate the Sixth Amendment. We have never doubted the authority of a judge to exercise broad discretion in imposing a sentence within a statutory range. See Apprendi, 530 U. S., at 481; Williams v. New York, 337 U. S. 241, 246 (1949). Indeed, everyone agrees that the constitutional issues presented by these cases would have been avoided entirely if Congress had omitted from the SRA the provisions that make the Guidelines binding on district judges; it is that circumstance that makes the Court's answer to the second question presented possible. For when a trial judge exercises his discretion to select a specific sentence within a defined range, the defendant has no right to a jury determination of the facts that the judge deems relevant.

The Guidelines as written, however, are not advisory; they are mandatory and binding on all judges.2 While subsection (a) of § 3553 of the sentencing statute3 lists the Sentencing Guidelines as one factor to be considered in imposing a sentence, subsection (b) directs that the court "shall impose a sentence of the kind, and within the range" established by the Guidelines, subject to departures in specific, limited cases. (Emphasis added.) Because they are binding on judges, we have consistently held that the Guidelines have the force and effect of laws. See, e. g., Mistretta v. United States, 488 U. S. 361, 391 (1989); Stinson v. United States, 508 U. S. 36, 42 (1993).

The availability of a departure in specified circumstances does not avoid the constitutional issue, just as it did not in Blakely itself. The Guidelines permit departures from the prescribed sentencing range in cases in which the judge "finds that there exists an aggravating or mitigating circumstance of a kind, or to a degree, not adequately taken into consideration by the Sentencing Commission in formulating the guidelines that should result in a sentence different from that described." 18 U. S. C. A. § 3553(b)(1) (Supp. 2004). At first glance, one might believe that the ability of a district judge to depart from the Guidelines means that she is bound only by the statutory maximum. Were this the case, there would be no Apprendi problem. Importantly, however, departures are not available in every case, and in fact are unavailable in most. In most cases, as a matter of law, the Commission will have adequately taken all relevant factors into account, and no departure will be legally permissible. In those instances, the judge is bound to impose a sentence within the Guidelines range. It was for this reason that we rejected a similar argument in Blakely, holding that although the Washington statute allowed the judge to impose a sentence outside the sentencing range for "`substantial and compelling reasons,'" that exception was not available for Blakely himself. 542 U. S., at 299. The sentencing judge would have been reversed had he invoked the departure section to justify the sentence.

Booker's case illustrates the mandatory nature of the Guidelines. The jury convicted him of possessing at least 50 grams of crack in violation of 21 U. S. C. § 841(b)(1)(A)(iii) based on evidence that he had 92.5 grams of crack in his duffel bag. Under these facts, the Guidelines specified an offense level of 32, which, given the defendant's criminal history category, authorized a sentence of 210-to-262 months. See USSG § 2D1.1(c)(4). Booker's is a run-of-the-mill drug case, and does not present any factors that were inadequately considered by the Commission. The sentencing judge would therefore have been reversed had he not imposed a sentence within the level 32 Guidelines range.

Booker's actual sentence, however, was 360 months, almost 10 years longer than the Guidelines range supported by the jury verdict alone. To reach this sentence, the judge found facts beyond those found by the jury: namely, that Booker possessed 566 grams of crack in addition to the 92.5 grams in his duffel bag. The jury never heard any evidence of the additional drug quantity, and the judge found it true by a preponderance of the evidence. Thus, just as in Blakely, "the jury's verdict alone does not authorize the sentence. The judge acquires that authority only upon finding some additional fact." 542 U. S., at 305. There is no relevant distinction between the sentence imposed pursuant to the Washington statutes in Blakely and the sentences imposed pursuant to the Federal Sentencing Guidelines in these cases.

In his dissent, post, at 327-329, JUSTICE BREYER argues on historical grounds that the Guidelines scheme is constitutional across the board. He points to traditional judicial authority to increase sentences to take account of any unusual blameworthiness in the manner employed in committing a crime, an authority that the Guidelines require to be exercised consistently throughout the system. This tradition, however, does not provide a sound guide to enforcement of the Sixth Amendment's guarantee of a jury trial in today's world.

It is quite true that once determinate sentencing had fallen from favor, American judges commonly determined facts justifying a choice of a heavier sentence on account of the manner in which particular defendants acted. Apprendi, 530 U. S., at 481. In 1986, however, our own cases first recognized a new trend in the legislative regulation of sentencing when we considered the significance of facts selected by legislatures that not only authorized, or even mandated, heavier sentences than would otherwise have been imposed, but increased the range of sentences possible for the underlying crime. See McMillan v. Pennsylvania, 477 U. S. 79, 87-88 (1986). Provisions for such enhancements of the permissible sentencing range reflected growing and wholly justified legislative concern about the proliferation and variety of drug crimes and their frequent identification with firearms offenses.

The effect of the increasing emphasis on facts that enhanced sentencing ranges, however, was to increase the judge's power and diminish that of the jury. It became the judge, not the jury, who determined the upper limits of sentencing, and the facts determined were not required to be raised before trial or proved by more than a preponderance.

As the enhancements became greater, the jury's finding of the underlying crime became less significant. And the enhancements became very serious indeed. See, e. g., Jones, 526 U. S., at 230-231 (judge's finding increased the maximum sentence from 15 to 25 years); respondent Booker's case (from 262 months to a life sentence); respondent Fanfan's case (from 78 to 235 months); United States v. Rodriguez, 73 F. 3d 161, 162-163 (CA7 1996) (Posner, C. J., dissenting from denial of rehearing en banc) (from approximately 54 months to a life sentence); United States v. Hammoud, 381 F. 3d 316, 361-362 (CA4 2004) (en banc) (Motz, J., dissenting) (actual sentence increased from 57 months to 155 years).

As it thus became clear that sentencing was no longer taking place in the tradition that JUSTICE BREYER invokes, the Court was faced with the issue of preserving an ancient guarantee under a new set of circumstances. The new sentencing practice forced the Court to address the question how the right of jury trial could be preserved, in a meaningful way guaranteeing that the jury would still stand between the individual and the power of the government under the new sentencing regime. And it is the new circumstances, not a tradition or practice that the new circumstances have superseded, that have led us to the answer first considered in Jones and developed in Apprendi and subsequent cases culminating with this one. It is an answer not motivated by Sixth Amendment formalism, but by the need to preserve Sixth Amendment substance.

The Government advances three arguments in support of its submission that we should not apply our reasoning in Blakely to the Federal Sentencing Guidelines. It contends that Blakely is distinguishable because the Guidelines were promulgated by a Commission rather than the Legislature; that principles of stare decisis require us to follow four earlier decisions that are arguably inconsistent with Blakely; and that the application of Blakely to the Guidelines would conflict with separation-of-powers principles reflected in Mistretta v. United States, 488 U. S. 361 (1989). These arguments are unpersuasive.

In our judgment the fact that the Guidelines were promulgated by the Sentencing Commission, rather than Congress, lacks constitutional significance. In order to impose the defendants' sentences under the Guidelines, the judges in these cases were required to find an additional fact, such as drug quantity, just as the judge found the additional fact of serious bodily injury to the victim in Jones. As far as the defendants are concerned, they face significantly higher sentences — in Booker's case almost 10 years higher — because a judge found true by a preponderance of the evidence a fact that was never submitted to the jury. Regardless of whether Congress or a Sentencing Commission concluded that a particular fact must be proved in order to sentence a defendant within a particular range, "[t]he Framers would not have thought it too much to demand that, before depriving a man of [ten] more years of his liberty, the State should suffer the modest inconvenience of submitting its accusation to `the unanimous suffrage of twelve of his equals and neighbours,' rather than a lone employee of the State." Blakely, 542 U. S., at 313-314 (citation omitted).

The Government correctly notes that in Apprendi we referred to "`any fact that increases the penalty for a crime beyond the prescribed statutory maximum . . . .'" Brief for United States 15 (quoting Apprendi, 530 U. S., at 490 (emphasis in Brief for United States)). The simple answer, of course, is that we were only considering a statute in that case; we expressly declined to consider the Guidelines. See Apprendi, 530 U. S., at 497, n. 21. It was therefore appropriate to state the rule in that case in terms of a "statutory maximum" rather than answering a question not properly before us.

More important than the language used in our holding in Apprendi are the principles we sought to vindicate. Those principles are unquestionably applicable to the Guidelines. They are not the product of recent innovations in our jurisprudence, but rather have their genesis in the ideals our constitutional tradition assimilated from the common law. See Jones, 526 U. S., at 244-248. The Framers of the Constitution understood the threat of "judicial despotism" that could arise from "arbitrary punishments upon arbitrary convictions" without the benefit of a jury in criminal cases. The Federalist No. 83, p. 499 (C. Rossiter ed. 1961) (A. Hamilton). The Founders presumably carried this concern from England, in which the right to a jury trial had been enshrined since the Magna Carta. As we noted in Apprendi:

"[T]he historical foundation for our recognition of these principles extends down centuries into the common law. `[T]o guard against a spirit of oppression and tyranny on the part of rulers,' and `as the great bulwark of [our] civil and political liberties,' trial by jury has been understood to require that `the truth of every accusation, whether preferred in the shape of indictment, information, or appeal, should afterwards be confirmed by the unanimous suffrage of twelve of [the defendant's] equals and neighbours . . . .'" 530 U. S., at 477 (citations omitted).

Regardless of whether the legal basis of the accusation is in a statute or in guidelines promulgated by an independent commission, the principles behind the jury trial right are equally applicable.

The Government next argues that four recent cases preclude our application of Blakely to the Sentencing Guidelines. We disagree. In United States v. Dunnigan, 507 U. S. 87 (1993), we held that the provisions of the Guidelines that require a sentence enhancement if the judge determines that the defendant committed perjury do not violate the privilege of the accused to testify on her own behalf. There was no contention that the enhancement was invalid because it resulted in a more severe sentence than the jury verdict had authorized. Accordingly, we found this case indistinguishable from United States v. Grayson, 438 U. S. 41 (1978), a pre-Guidelines case in which we upheld a similar sentence increase. Applying Blakely to the Guidelines would invalidate a sentence that relied on such an enhancement if the resulting sentence was outside the range authorized by the jury verdict. Nevertheless, there are many situations in which the district judge might find that the enhancement is warranted, yet still sentence the defendant within the range authorized by the jury. See post, at 276-279 (STEVENS, J., dissenting in part). Thus, while the reach of Dunnigan may be limited, we need not overrule it.

In Witte v. United States, 515 U. S. 389 (1995), we held that the Double Jeopardy Clause did not bar a prosecution for conduct that had provided the basis for an enhancement of the defendant's sentence in a prior case. "We concluded that `consideration of information about the defendant's character and conduct at sentencing does not result in "punishment" for any offense other than the one of which the defendant was convicted.' Rather, the defendant is `punished only for the fact that the present offense was carried out in a manner that warrants increased punishment . . . .'" United States v. Watts, 519 U. S. 148, 155 (1997) (per curiam) (emphasis deleted) (quoting Witte, 515 U. S., at 401, 403). In Watts, relying on Witte, we held that the Double Jeopardy Clause permitted a court to consider acquitted conduct in sentencing a defendant under the Guidelines. In neither Witte nor Watts was there any contention that the sentencing enhancement had exceeded the sentence authorized by the jury verdict in violation of the Sixth Amendment. The issue we confront today simply was not presented.4

Finally, in Edwards v. United States, 523 U. S. 511 (1998), the Court held that a jury's general verdict finding the defendants guilty of a conspiracy involving either cocaine or crack supported a sentence based on their involvement with both drugs. Even though the indictment had charged that their conspiracy embraced both, they argued on appeal that the verdict limited the judge's sentencing authority. We recognized that the defendants' statutory and constitutional claims might have had merit if it had been possible to argue that their crack-related activities were not part of the same conspiracy as their cocaine activities. But they failed to make that argument, and, based on our review of the record which showed "a series of interrelated drug transactions involving both cocaine and crack," we concluded that no such claim could succeed.5 Id., at 515.

None of our prior cases is inconsistent with today's decision. Stare decisis does not compel us to limit Blakely's holding.

Finally, the Government and, to a lesser extent, JUSTICE BREYER's dissent, argue that any holding that would require Guidelines sentencing factors to be proved to a jury beyond a reasonable doubt would effectively transform them into a code defining elements of criminal offenses. The result, according to the Government, would be an unconstitutional grant to the Sentencing Commission of the inherently legislative power to define criminal elements.

There is no merit to this argument because the Commission's authority to identify the facts relevant to sentencing decisions and to determine the impact of such facts on federal sentences is precisely the same whether one labels such facts "sentencing factors" or "elements" of crimes. Our decision in Mistretta, 488 U. S., at 371, upholding the validity of the delegation of that authority, is unaffected by the characterization of such facts, or by the procedures used to find such facts in particular sentencing proceedings. Indeed, we rejected a similar argument in Jones:

"Contrary to the dissent's suggestion, the constitutional proposition that drives our concern in no way `call[s] into question the principle that the definition of the elements of a criminal offense is entrusted to the legislature.' The constitutional guarantees that give rise to our concern in no way restrict the ability of legislatures to identify the conduct they wish to characterize as criminal or to define the facts whose proof is essential to the establishment of criminal liability. The constitutional safeguards that figure in our analysis concern not the identity of the elements defining criminal liability but only the required procedures for finding the facts that determine the maximum permissible punishment; these are the safeguards going to the formality of notice, the identity of the factfinder, and the burden of proof." 526 U. S., at 243, n. 6 (citation omitted).

Our holding today does not call into question any aspect of our decision in Mistretta. That decision was premised on an understanding that the Commission, rather than performing adjudicatory functions, instead makes political and substantive decisions. 488 U. S., at 393. We noted that the promulgation of the Guidelines was much like other activities in the Judicial Branch, such as the creation of the Federal Rules of Evidence, all of which are nonadjudicatory activities. Id., at 387. We also noted that "Congress may delegate to the Judicial Branch nonadjudicatory functions that do not trench upon the prerogatives of another Branch and that are appropriate to the central mission of the Judiciary." Id., at 388. While we recognized that the Guidelines were more substantive than the Rules of Evidence or other nonadjudicatory functions delegated to the Judicial Branch, we nonetheless concluded that such a delegation did not exceed Congress' powers.

Further, a recognition that the Commission did not exercise judicial authority, but was more properly thought of as exercising some sort of legislative power, ibid., was essential to our holding. If the Commission in fact performed adjudicatory functions, it would have violated Article III because some of the members were not Article III judges. As we explained:

"[T]he `practical consequences' of locating the Commission within the Judicial Branch pose no threat of undermining the integrity of the Judicial Branch or of expanding the powers of the Judiciary beyond constitutional bounds by uniting within the Branch the political or quasi-legislative power of the Commission with the judicial power of the courts. [The Commission's] powers are not united with the powers of the Judiciary in a way that has meaning for separation-of-powers analysis. Whatever constitutional problems might arise if the powers of the Commission were vested in a court, the Commission is not a court, does not exercise judicial power, and is not controlled by or accountable to members of the Judicial Branch." Id., at 393.

We have thus always recognized the fact that the Commission is an independent agency that exercises policymaking authority delegated to it by Congress. Nothing in our holding today is inconsistent with our decision in Mistretta.

All of the foregoing supports our conclusion that our holding in Blakely applies to the Sentencing Guidelines. We recognize, as we did in Jones, Apprendi, and Blakely, that in some cases jury factfinding may impair the most expedient and efficient sentencing of defendants. But the interest in fairness and reliability protected by the right to a jury trial — a common-law right that defendants enjoyed for centuries and that is now enshrined in the Sixth Amendment — has always outweighed the interest in concluding trials swiftly. Blakely, 542 U. S., at 313. As Blackstone put it:

"[H]owever convenient these [new methods of trial] may appear at first, (as doubtless all arbitrary powers, well executed, are the most convenient) yet let it be again remembered, that delays, and little inconveniences in the forms of justice, are the price that all free nations must pay for their liberty in more substantial matters; that these inroads upon this sacred bulwark of the nation are fundamentally opposite to the spirit of our constitution; and that, though begun in trifles, the precedent may gradually increase and spread, to the utter disuse of juries in questions of the most momentous concerns." 4 Commentaries on the Laws of England 343-344 (1769).

Accordingly, we reaffirm our holding in Apprendi: Any fact (other than a prior conviction) which is necessary to support a sentence exceeding the maximum authorized by the facts established by a plea of guilty or a jury verdict must be admitted by the defendant or proved to a jury beyond a reasonable doubt.

JUSTICE BREYER delivered the opinion of the Court in part.*

The first question that the Government has presented in these cases is the following: "Whether the Sixth Amendment is violated by the imposition of an enhanced sentence under the United States Sentencing Guidelines based on the sentencing judge's determination of a fact (other than a prior conviction) that was not found by the jury or admitted by the defendant." Pet. for Cert. in No. 04-104, p. (I).

The Court, in an opinion by JUSTICE STEVENS, answers this question in the affirmative. Applying its decisions in Apprendi v. New Jersey, 530 U. S. 466 (2000), and Blakely v. Washington, 542 U. S. 296 (2004), to the Federal Sentencing Guidelines, the Court holds that, in the circumstances mentioned, the Sixth Amendment requires juries, not judges, to find facts relevant to sentencing. See ante, at 226-227, 244 (STEVENS, J., opinion of the Court).

We here turn to the second question presented, a question that concerns the remedy. We must decide whether or to what extent, "as a matter of severability analysis," the Guidelines "as a whole" are "inapplicable . . . such that the sentencing court must exercise its discretion to sentence the defendant within the maximum and minimum set by statute for the offense of conviction." Pet. for Cert. in No. 04-104, p. (I).

We answer the question of remedy by finding the provision of the federal sentencing statute that makes the Guidelines mandatory, 18 U. S. C. A. § 3553(b)(1) (Supp. 2004), incompatible with today's constitutional holding. We conclude that this provision must be severed and excised, as must one other statutory section, § 3742(e) (main ed. and Supp. 2004), which depends upon the Guidelines' mandatory nature. So modified, the federal sentencing statute, see Sentencing Reform Act of 1984 (Sentencing Act), as amended, 18 U. S. C. § 3551 et seq., 28 U. S. C. § 991 et seq., makes the Guidelines effectively advisory. It requires a sentencing court to consider Guidelines ranges, see 18 U. S. C. A. § 3553(a)(4) (Supp. 2004), but it permits the court to tailor the sentence in light of other statutory concerns as well, see § 3553(a) (Supp. 2004).

* We answer the remedial question by looking to legislative intent. See, e. g., Minnesota v. Mille Lacs Band of Chippewa Indians, 526 U. S. 172, 191 (1999); Alaska Airlines, Inc. v. Brock, 480 U. S. 678, 684 (1987); Regan v. Time, Inc., 468 U. S. 641, 653 (1984) (plurality opinion). We seek to determine what "Congress would have intended" in light of the Court's constitutional holding. Denver Area Ed. Telecommunications Consortium, Inc. v. FCC, 518 U. S. 727, 767 (1996) (plurality opinion) ("Would Congress still have passed" the valid sections "had it known" about the constitutional invalidity of the other portions of the statute? (internal quotation marks omitted)). In this instance, we must determine which of the two following remedial approaches is the more compatible with the Legislature's intent as embodied in the 1984 Sentencing Act.

One approach, that of JUSTICE STEVENS' dissent, would retain the Sentencing Act (and the Guidelines) as written, but would engraft onto the existing system today's Sixth Amendment "jury trial" requirement. The addition would change the Guidelines by preventing the sentencing court from increasing a sentence on the basis of a fact that the jury did not find (or that the offender did not admit).

The other approach, which we now adopt, would (through severance and excision of two provisions) make the Guidelines system advisory while maintaining a strong connection between the sentence imposed and the offender's real conduct — a connection important to the increased uniformity of sentencing that Congress intended its Guidelines system to achieve.

Both approaches would significantly alter the system that Congress designed. But today's constitutional holding means that it is no longer possible to maintain the judicial factfinding that Congress thought would underpin the mandatory Guidelines system that it sought to create and that Congress wrote into the Act in 18 U. S. C. A. §§ 3553(a) and 3661 (main ed. and Supp. 2004). Hence we must decide whether we would deviate less radically from Congress' intended system (1) by superimposing the constitutional requirement announced today or (2) through elimination of some provisions of the statute.

To say this is not to create a new kind of severability analysis. Post, at 291 (STEVENS, J., dissenting in part). Rather, it is to recognize that sometimes severability questions (questions as to how, or whether, Congress would intend a statute to apply) can arise when a legislatively unforeseen constitutional problem requires modification of a statutory provision as applied in a significant number of instances. Compare, e. g., Welsh v. United States, 398 U. S. 333, 361 (1970) (Harlan, J., concurring in result) (explaining that when a statute is defective because of its failure to extend to some group a constitutionally required benefit, the court may "either declare it a nullity" or "extend" the benefit "to include those who are aggrieved by exclusion"); Heckler v. Mathews, 465 U. S. 728, 739, n. 5 (1984) ("Although . . . ordinarily `extension, rather than nullification, is the proper course,' the court should not, of course, `use its remedial powers to circumvent the intent of the legislature . . . .'" (quoting Califano v. Westcott, 443 U. S. 76, 89 (1979) and id., at 94 (Powell, J., concurring in part and dissenting in part))); Sloan v. Lemon, 413 U. S. 825, 834 (1973) (striking down entire Pennsylvania tuition reimbursement statute because to eliminate only unconstitutional applications "would be to create a program quite different from the one the legislature actually adopted"). See also post, at 320, 323 (THOMAS, J., dissenting in part) ("[S]everability questions" can "arise from unconstitutional applications" of statutes, and such a question "is squarely presented" here); Vermeule, Saving Constructions, 85 Geo. L. J. 1945, 1950, n. 26 (1997).

In today's context — a highly complex statute, interrelated provisions, and a constitutional requirement that creates fundamental change — we cannot assume that Congress, if faced with the statute's invalidity in key applications, would have preferred to apply the statute in as many other instances as possible. Neither can we determine likely congressional intent mechanically. We cannot simply approach the problem grammatically, say, by looking to see whether the constitutional requirement and the words of the Act are linguistically compatible.

Nor do simple numbers provide an answer. It is, of course, true that the numbers show that the constitutional jury trial requirement would lead to additional decisionmaking by juries in only a minority of cases. See post, at 277 (STEVENS, J., dissenting in part). Prosecutors and defense attorneys would still resolve the lion's share of criminal matters through plea bargaining, and plea bargaining takes place without a jury. See ibid. Many of the rest involve only simple issues calling for no upward Guidelines adjustment. See post, at 275. And in at least some of the remainder, a judge may find adequate room to adjust a sentence within the single Guidelines range to which the jury verdict points, or within the overlap between that range and the next highest. See post, at 278-279.

But the constitutional jury trial requirement would nonetheless affect every case. It would affect decisions about whether to go to trial. It would affect the content of plea negotiations. It would alter the judge's role in sentencing. Thus we must determine likely intent not by counting proceedings, but by evaluating the consequences of the Court's constitutional requirement in light of the Act's language, its history, and its basic purposes.

While reasonable minds can, and do, differ about the outcome, we conclude that the constitutional jury trial requirement is not compatible with the Act as written and that some severance and excision are necessary. In Part II, infra, we explain the incompatibility. In Part III, infra, we describe the necessary excision. In Part IV, infra, we explain why we have rejected other possibilities. In essence, in what follows, we explain both (1) why Congress would likely have preferred the total invalidation of the Act to an Act with the Court's Sixth Amendment requirement engrafted onto it, and (2) why Congress would likely have preferred the excision of some of the Act, namely the Act's mandatory language, to the invalidation of the entire Act. That is to say, in light of today's holding, we compare maintaining the Act as written with jury factfinding added (the dissenters' proposed remedy) to the total invalidation of the statute, and conclude that Congress would have preferred the latter. We then compare our own remedy to the total invalidation of the statute, and conclude that Congress would have preferred our remedy.

Several considerations convince us that, were the Court's constitutional requirement added onto the Sentencing Act as currently written, the requirement would so transform the scheme that Congress created that Congress likely would not have intended the Act as so modified to stand. First, the statute's text states that "[t]he court" when sentencing will consider "the nature and circumstances of the offense and the history and characteristics of the defendant." 18 U. S. C. A. § 3553(a)(1) (main ed. and Supp. 2004). In context, the words "the court" mean "the judge without the jury," not "the judge working together with the jury." A further statutory provision, by removing typical "jury trial" evidentiary limitations, makes this clear. See § 3661 (ruling out any "limitation . . . on the information concerning the [offender's] background, character, and conduct" that the "court . . . may receive"). The Act's history confirms it. See, e. g., S. Rep. No. 98-225, p. 51 (1983) (the Guidelines system "will guide the judge in making" sentencing decisions (emphasis added)); id., at 52 (before sentencing, "the judge" must consider "the nature and circumstances of the offense"); id., at 53 ("the judge" must conduct "a comprehensive examination of the characteristics of the particular offense and the particular offender").

This provision is tied to the provision of the Act that makes the Guidelines mandatory, see § 3553(b)(1) (Supp. 2004). They are part and parcel of a single, unified whole — a whole that Congress intended to apply to all federal sentencing.

This provision makes it difficult to justify JUSTICE STEVENS' approach, for that approach requires reading the words "the court" as if they meant "the judge working together with the jury." Unlike JUSTICE STEVENS, we do not believe we can interpret the statute's language to save its constitutionality, see post, at 286 (opinion dissenting in part), because we believe that any such reinterpretation, even if limited to instances in which a Sixth Amendment problem arises, would be "plainly contrary to the intent of Congress." United States v. X-Citement Video, Inc., 513 U. S. 64, 78 (1994). Without some such reinterpretation, however, this provision of the statute, along with those inextricably connected to it, are constitutionally invalid, and fall outside of Congress' power to enact. Nor can we agree with JUSTICE STEVENS that a newly passed "identical statute" would be valid, post, at 283 (opinion dissenting in part). Such a new, identically worded statute would be valid only if (unlike the present statute) we could interpret that new statute (without disregarding Congress' basic intent) as being consistent with the Court's jury factfinding requirement. Compare post, at 283-284 (STEVENS, J., dissenting in part). If so, the statute would stand.

Second, Congress' basic statutory goal — a system that diminishes sentencing disparity — depends for its success upon judicial efforts to determine, and to base punishment upon, the real conduct that underlies the crime of conviction. That determination is particularly important in the federal system where crimes defined as, for example, "obstruct[ing], delay[ing], or affect[ing] commerce or the movement of any article or commodity in commerce, by . . . extortion," 18 U. S. C. § 1951(a), or, say, using the mail "for the purpose of executing" a "scheme or artifice to defraud," § 1341 (2000 ed., Supp. II), can encompass a vast range of very different kinds of underlying conduct. But it is also important even in respect to ordinary crimes, such as robbery, where an act that meets the statutory definition can be committed in a host of different ways. Judges have long looked to real conduct when sentencing. Federal judges have long relied upon a presentence report, prepared by a probation officer, for information (often unavailable until after the trial) relevant to the manner in which the convicted offender committed the crime of conviction.

Congress expected this system to continue. That is why it specifically inserted into the Act the provision cited above, which (recodifying prior law) says that

"[n]o limitation shall be placed on the information concerning the background, character, and conduct of a person convicted of an offense which a court of the United States may receive and consider for the purpose of imposing an appropriate sentence." 18 U. S. C. § 3661.

This Court's earlier opinions assumed that this system would continue. That is why the Court, for example, held in United States v. Watts, 519 U. S. 148 (1997) (per curiam), that a sentencing judge could rely for sentencing purposes upon a fact that a jury had found unproved (beyond a reasonable doubt). See id., at 157; see also id., at 152-153 (quoting United States Sentencing Commission, Guidelines Manual § 1B1.3, comment., backg'd (Nov. 1995) (USSG), which "describes in sweeping language the conduct that a sentencing court may consider in determining the applicable guideline range," and which provides that "`[c]onduct that is not formally charged or is not an element of the offense of conviction may enter into the determination of the applicable guideline sentencing range'").

The Sentencing Guidelines also assume that Congress intended this system to continue. See USSG § 1B1.3, comment., backg'd (Nov. 2003). That is why, among other things, they permit a judge to reject a plea-bargained sentence if he determines, after reviewing the presentence report, that the sentence does not adequately reflect the seriousness of the defendant's actual conduct. See § 6B1.2(a).

To engraft the Court's constitutional requirement onto the sentencing statutes, however, would destroy the system. It would prevent a judge from relying upon a presentence report for factual information, relevant to sentencing, uncovered after the trial. In doing so, it would, even compared to pre-Guidelines sentencing, weaken the tie between a sentence and an offender's real conduct. It would thereby undermine the sentencing statute's basic aim of ensuring similar sentences for those who have committed similar crimes in similar ways.

Several examples help illustrate the point. Imagine Smith and Jones, each of whom violates the Hobbs Act in very different ways. See 18 U. S. C. § 1951(a) (forbidding "obstruct[ing], delay[ing], or affect[ing] commerce or the movement of any article or commodity in commerce, by ... extortion"). Smith threatens to injure a co-worker unless the co-worker advances him a few dollars from the interstate company's till; Jones, after similarly threatening the co-worker, causes far more harm by seeking far more money, by making certain that the co-worker's family is aware of the threat, by arranging for deliveries of dead animals to the co-worker's home to show he is serious, and so forth. The offenders' behavior is very different; the known harmful consequences of their actions are different; their punishments both before, and after, the Guidelines would have been different. But, under the dissenters' approach, unless prosecutors decide to charge more than the elements of the crime, the judge would have to impose similar punishments. See, e. g., post, at 303-304 (SCALIA, J., dissenting in part).

Now imagine two former felons, Johnson and Jackson, each of whom engages in identical criminal behavior: threatening a bank teller with a gun, securing $50,000, and injuring an innocent bystander while fleeing the bank. Suppose prosecutors charge Johnson with one crime (say, illegal gun possession, see 18 U. S. C. § 922(g)) and Jackson with another (say, bank robbery, see § 2113(a)). Before the Guidelines, a single judge faced with such similar real conduct would have been able (within statutory limits) to impose similar sentences upon the two similar offenders despite the different charges brought against them. The Guidelines themselves would ordinarily have required judges to sentence the two offenders similarly. But under the dissenters' system, in these circumstances the offenders likely would receive different punishments. See, e. g., post, at 303-304 (SCALIA, J., dissenting in part).

Consider, too, a complex mail fraud conspiracy where a prosecutor may well be uncertain of the amount of harm and of the role each indicted individual played until after conviction — when the offenders may turn over financial records, when it becomes easier to determine who were the leaders and who the followers, when victim interviews are seen to be worth the time. In such a case the relation between the sentence and what actually occurred is likely to be considerably more distant under a system with a jury trial requirement patched onto it than it was even prior to the Sentencing Act, when judges routinely used information obtained after the verdict to decide upon a proper sentence.

This point is critically important. Congress' basic goal in passing the Sentencing Act was to move the sentencing system in the direction of increased uniformity. See 28 U. S. C. § 991(b)(1)(B); see also § 994(f). That uniformity does not consist simply of similar sentences for those convicted of violations of the same statute — a uniformity consistent with the dissenters' remedial approach. It consists, more importantly, of similar relationships between sentences and real conduct, relationships that Congress' sentencing statutes helped to advance and that JUSTICE STEVENS' approach would undermine. Compare post, at 288 (opinion dissenting in part) (conceding that the Sixth Amendment requirement would "undoubtedly affect `real conduct' sentencing in certain cases," but minimizing the significance of that circumstance). In significant part, it is the weakening of this real-conduct/uniformity-in-sentencing relationship, and not any "[i]nexplicabl[e]" concerns for the "manner of achieving uniform sentences," post, at 304 (SCALIA, J., dissenting in part), that leads us to conclude that Congress would have preferred no mandatory system to the system the dissenters envisage.

Third, the sentencing statutes, read to include the Court's Sixth Amendment requirement, would create a system far more complex than Congress could have intended. How would courts and counsel work with an indictment and a jury trial that involved not just whether a defendant robbed a bank but also how? Would the indictment have to allege, in addition to the elements of robbery, whether the defendant possessed a firearm, whether he brandished or discharged it, whether he threatened death, whether he caused bodily injury, whether any such injury was ordinary, serious, permanent or life threatening, whether he abducted or physically restrained anyone, whether any victim was unusually vulnerable, how much money was taken, and whether he was an organizer, leader, manager, or supervisor in a robbery gang? See USSG §§ 2B3.1, 3B1.1. If so, how could a defendant mount a defense against some or all such specific claims should he also try simultaneously to maintain that the Government's evidence failed to place him at the scene of the crime? Would the indictment in a mail fraud case have to allege the number of victims, their vulnerability, and the amount taken from each? How could a judge expect a jury to work with the Guidelines' definitions of, say, "relevant conduct," which includes "all acts and omissions committed, aided, abetted, counseled, commanded, induced, procured, or willfully caused by the defendant; and [in the case of a conspiracy] all reasonably foreseeable acts and omissions of others in furtherance of the jointly undertaken criminal activity"? §§ 1B1.3(a)(1)(A)-(B). How would a jury measure "loss" in a securities fraud case — a matter so complex as to lead the Commission to instruct judges to make "only ... a reasonable estimate"? § 2B1.1, comment., n. 3(C). How would the court take account, for punishment purposes, of a defendant's contemptuous behavior at trial — a matter that the Government could not have charged in the indictment? § 3C1.1.

Fourth, plea bargaining would not significantly diminish the consequences of the Court's constitutional holding for the operation of the Guidelines. Compare post, at 273-274 (STEVENS, J., dissenting in part). Rather, plea bargaining would make matters worse. Congress enacted the sentencing statutes in major part to achieve greater uniformity in sentencing, i. e., to increase the likelihood that offenders who engage in similar real conduct would receive similar sentences. The statutes reasonably assume that their efforts to move the trial-based sentencing process in the direction of greater sentencing uniformity would have a similar positive impact upon plea-bargained sentences, for plea bargaining takes place in the shadow of (i. e., with an eye towards the hypothetical result of) a potential trial.

That, too, is why Congress, understanding the realities of plea bargaining, authorized the Commission to promulgate policy statements that would assist sentencing judges in determining whether to reject a plea agreement after reading about the defendant's real conduct in a presentence report (and giving the offender an opportunity to challenge the report). See 28 U. S. C. § 994(a)(2)(E); USSG § 6B1.2(a), p. s. This system has not worked perfectly; judges have often simply accepted an agreed-upon account of the conduct at issue. But compared to pre-existing law, the statutes try to move the system in the right direction, i. e., toward greater sentencing uniformity.

The Court's constitutional jury trial requirement, however, if patched onto the present Sentencing Act, would move the system backwards in respect both to tried and to plea-bargained cases. In respect to tried cases, it would effectively deprive the judge of the ability to use post-verdict-acquired real-conduct information; it would prohibit the judge from basing a sentence upon any conduct other than the conduct the prosecutor chose to charge; and it would put a defendant to a set of difficult strategic choices as to which prosecutorial claims he would contest. The sentence that would emerge in a case tried under such a system would likely reflect real conduct less completely, less accurately, and less often than did a pre-Guidelines, as well as a Guidelines, trial.

Because plea bargaining inevitably reflects estimates of what would happen at trial, plea bargaining too under such a system would move in the wrong direction. That is to say, in a sentencing system modified by the Court's constitutional requirement, plea bargaining would likely lead to sentences that gave greater weight not to real conduct, but rather to the skill of counsel, the policies of the prosecutor, the case-load, and other factors that vary from place to place, defendant to defendant, and crime to crime. Compared to pre-Guidelines plea bargaining, plea bargaining of this kind would necessarily move federal sentencing in the direction of diminished, not increased, uniformity in sentencing. Compare supra, at 250-252, with post, at 288 (STEVENS, J., dissenting in part). It would tend to defeat, not to further, Congress' basic statutory goal.

Such a system would have particularly troubling consequences with respect to prosecutorial power. Until now, sentencing factors have come before the judge in the presentence report. But in a sentencing system with the Court's constitutional requirement engrafted onto it, any factor that a prosecutor chose not to charge at the plea negotiation would be placed beyond the reach of the judge entirely. Prosecutors would thus exercise a power the Sentencing Act vested in judges: the power to decide, based on relevant information about the offense and the offender, which defendants merit heavier punishment.

In respondent Booker's case, for example, the jury heard evidence that the crime had involved 92.5 grams of crack cocaine, and convicted Booker of possessing more than 50 grams. But the judge, at sentencing, found that the crime had involved an additional 566 grams, for a total of 658.5 grams. A system that would require the jury, not the judge, to make the additional "566 grams" finding is a system in which the prosecutor, not the judge, would control the sentence. That is because it is the prosecutor who would have to decide what drug amount to charge. He could choose to charge 658.5 grams, or 92.5, or less. It is the prosecutor who, through such a charging decision, would control the sentencing range. And it is different prosecutors who, in different cases — say, in two cases involving 566 grams — would potentially insist upon different punishments for similar defendants who engaged in similar criminal conduct involving similar amounts of unlawful drugs — say, by charging one of them with the full 566 grams, and the other with 10. As long as different prosecutors react differently, a system with a patched-on jury factfinding requirement would mean different sentences for otherwise similar conduct, whether in the context of trials or that of plea bargaining.

Fifth, Congress would not have enacted sentencing statutes that make it more difficult to adjust sentences upward than to adjust them downward. As several United States Senators have written in an amicus brief, "the Congress that enacted the 1984 Act did not conceive of — much less establish — a sentencing guidelines system in which sentencing judges were free to consider facts or circumstances not found by a jury or admitted in a plea agreement for the purpose of adjusting a base-offense level down, but not up, within the applicable guidelines range. Such a one-way lever would be grossly at odds with Congress's intent." Brief for Sen. Orrin G. Hatch et al. as Amici Curiae 22. Yet that is the system that the dissenters' remedy would create. Compare post, at 291 (STEVENS, J., dissenting in part) (conceding asymmetry but stating belief that this "is unlikely to have more than a minimal effect").

For all these reasons, Congress, had it been faced with the constitutional jury trial requirement, likely would not have passed the same Sentencing Act. It likely would have found the requirement incompatible with the Act as written. Hence the Act cannot remain valid in its entirety. Severance and excision are necessary.

We now turn to the question of which portions of the sentencing statute we must sever and excise as inconsistent with the Court's constitutional requirement. Although, as we have explained, see Part II, supra, we believe that Congress would have preferred the total invalidation of the statute to the dissenters' remedial approach, we nevertheless do not believe that the entire statute must be invalidated. Compare post, at 292 (STEVENS, J., dissenting in part). Most of the statute is perfectly valid. See, e.g., 18 U. S. C. A. § 3551 (main ed. and Supp. 2004) (describing authorized sentences as probation, fine, or imprisonment); § 3552 (presentence reports); § 3554 (forfeiture); § 3555 (notification to the victims); § 3583 (supervised release). And we must "refrain from invalidating more of the statute than is necessary." Regan, 468 U.S., at 652 (plurality opinion). Indeed, we must retain those portions of the Act that are (1) constitutionally valid, id., at 652-653, (2) capable of "functioning independently," Alaska Airlines, 480 U. S., at 684, and (3) consistent with Congress' basic objectives in enacting the statute, Regan, supra, at 653.

Application of these criteria indicates that we must sever and excise two specific statutory provisions: the provision that requires sentencing courts to impose a sentence within the applicable Guidelines range (in the absence of circumstances that justify a departure), see 18 U. S. C. A. § 3553(b)(1) (Supp. 2004), and the provision that sets forth standards of review on appeal, including de novo review of departures from the applicable Guidelines range, see § 3742(e) (main ed. and Supp. 2004) (see Appendix, infra, for text of both provisions). With these two sections excised (and statutory cross-references to the two sections consequently invalidated), the remainder of the Act satisfies the Court's constitutional requirements.

As the Court today recognizes in its first opinion in these cases, the existence of § 3553(b)(1) is a necessary condition of the constitutional violation. That is to say, without this provision — namely the provision that makes "the relevant sentencing rules . . . mandatory and impose[s] binding requirements on all sentencing judges" — the statute falls outside the scope of Apprendi's requirement. Ante, at 233 (STEVENS, J., opinion of the Court); see also ibid. ("[E]veryone agrees that the constitutional issues presented by these cases would have been avoided entirely if Congress had omitted from the [Sentencing Reform Act] the provisions that make the Guidelines binding on district judges"). Cf. post, at 314-320 (THOMAS, J., dissenting in part).

The remainder of the Act "function[s] independently." Alaska Airlines, supra, at 684. Without the "mandatory" provision, the Act nonetheless requires judges to take account of the Guidelines together with other sentencing goals. See 18 U. S. C. A. § 3553(a) (Supp. 2004). The Act nonetheless requires judges to consider the Guidelines "sentencing range established for . . . the applicable category of offense committed by the applicable category of defendant," § 3553(a)(4)(A), the pertinent Sentencing Commission policy statements, the need to avoid unwarranted sentencing disparities, and the need to provide restitution to victims, §§ 3553(a)(1), (3), (5)-(7) (main ed. and Supp. 2004). And the Act nonetheless requires judges to impose sentences that reflect the seriousness of the offense, promote respect for the law, provide just punishment, afford adequate deterrence, protect the public, and effectively provide the defendant with needed educational or vocational training and medical care. § 3553(a)(2) (main ed. and Supp. 2004) (see Appendix, infra, for text of § 3553(a)).

Moreover, despite the absence of § 3553(b)(1) (Supp. 2004), the Act continues to provide for appeals from sentencing decisions (irrespective of whether the trial judge sentences within or outside the Guidelines range in the exercise of his discretionary power under § 3553(a)). See § 3742(a) (appeal by defendant); § 3742(b) (appeal by Government). We concede that the excision of § 3553(b)(1) requires the excision of a different, appeals-related section, namely § 3742(e) (main ed. and Supp. 2004), which sets forth standards of review on appeal. That section contains critical cross-references to the (now-excised) § 3553(b)(1) and consequently must be severed and excised for similar reasons.

Excision of § 3742(e), however, does not pose a critical problem for the handling of appeals. That is because, as we have previously held, a statute that does not explicitly set forth a standard of review may nonetheless do so implicitly. See Pierce v. Underwood, 487 U. S. 552, 558-560 (1988) (adopting a standard of review, where "neither a clear statutory prescription nor a historical tradition" existed, based on the statutory text and structure, and on practical considerations); see also Cooter & Gell v. Hartmarx Corp., 496 U. S. 384, 403-405 (1990) (same); Koon v. United States, 518 U. S. 81, 99 (1996) (citing Pierce and Cooter & Gell with approval). We infer appropriate review standards from related statutory language, the structure of the statute, and the "`sound administration of justice.'" Pierce, supra, at 559-560. And in this instance those factors, in addition to the past two decades of appellate practice in cases involving departures, imply a practical standard of review already familiar to appellate courts: review for "unreasonable[ness]." 18 U. S. C. § 3742(e)(3) (1994 ed.).

Until 2003, § 3742(e) explicitly set forth that standard. See § 3742(e)(3) (1994 ed.). In 2003, Congress modified the pre-existing text, adding a de novo standard of review for departures and inserting cross-references to § 3553(b)(1). Prosecutorial Remedies and Other Tools to end the Exploitation of Children Today Act of 2003, Pub. L. 108-21, § 401(d)(1), 117 Stat. 670. In light of today's holding, the reasons for these revisions — to make Guidelines sentencing even more mandatory than it had been — have ceased to be relevant. The pre-2003 text directed appellate courts to review sentences that reflected an applicable Guidelines range for correctness, but to review other sentences — those that fell "outside the applicable Guideline range" — with a view toward determining whether such a sentence

"is unreasonable, having regard for ... the factors to be considered in imposing a sentence, as set forth in chapter 227 of this title; and . . . the reasons for the imposition
