Justice SOTOMAYOR delivered the opinion of the Court.

Federal Rule of Criminal Procedure 52(b) provides that a court of appeals may consider errors that are plain and affect substantial rights, even though they are raised for the first time on appeal. This case concerns the bounds of that discretion, and whether a miscalculation of the United States Sentencing Guidelines range, that has been determined to be plain and to affect a defendant's substantial rights, calls for a court of appeals to exercise its discretion under Rule 52(b) to vacate the defendant's sentence. The Court holds that such an error will in the ordinary case, as here, seriously affect the fairness, integrity, or public reputation of judicial proceedings, and thus will warrant relief.

Each year, thousands of individuals are sentenced to terms of imprisonment for violations of federal law. District courts must determine in each case what constitutes a sentence that is "sufficient, but not greater than necessary," 18 U.S.C. § 3553(a), to achieve the overarching sentencing purposes of "retribution, deterrence, incapacitation, and rehabilitation." Tapia v. United States, 564 U.S. 319, 325, 131 S.Ct. 2382, 180 L.Ed.2d 357 (2011) ; 18 U.S.C. §§ 3551(a), 3553(a)(2). Those decisions call for the district court to exercise discretion. Yet, to ensure " ‘certainty and fairness' " in sentencing, district courts must operate within the framework established by Congress. United States v. Booker, 543 U.S. 220, 264, 125 S.Ct. 738, 160 L.Ed.2d 621 (2005) (quoting 28 U.S.C. § 991(b)(1)(B) ).

The Sentencing Guidelines serve an important role in that framework. " ‘[D]istrict courts must begin their analysis with the Guidelines and remain cognizant of them throughout the sentencing process.’ " Peugh v. United States, 569 U.S. 530, 541, 133 S.Ct. 2072, 186 L.Ed.2d 84 (2013) (quoting Gall v. United States, 552 U.S. 38, 50, n. 6, 128 S.Ct. 586, 169 L.Ed.2d 445 (2007) ; emphasis in original). Courts are not bound by the Guidelines, but even in an advisory capacity the Guidelines serve as "a meaningful benchmark" in the initial determination of a sentence and "through the process of appellate review." 569 U.S., at 541, 133 S.Ct. 2072.

Of course, to consult the applicable Guidelines range, a district court must first determine what that range is. This can be a "complex" undertaking. Molina–Martinez v. United States, 578 U.S. ––––, ––––, 136 S.Ct. 1338, 1342, 194 L.Ed.2d 444 (2016). The United States Probation Office, operating as an arm of the district court, first creates a presentence investigation report, "which includes a calculation of the advisory Guidelines range it considers to be applicable." Id., at ––––, 136 S.Ct., at 1342 ; see Fed. Rules Crim. Proc. 32(c)(1)(A), (d)(1) ; United States Sentencing Commission, Guidelines Manual § 1B1.1(a) (Nov. 2016) (USSG). That calculation derives from an assessment of the "offense characteristics, offender characteristics, and other matters that might be relevant to the sentence." Rita v. United States, 551 U.S. 338, 342, 127 S.Ct. 2456, 168 L.Ed.2d 203 (2007) (internal quotation marks omitted). Specifically, an offense level is calculated by identifying a base level for the offense of conviction and adjusting that level to account for circumstances specific to the defendant's case, such as how the crime was committed and whether the defendant accepted responsibility. See USSG §§ 1B1.1(a)(1)-(5). A numerical value is then attributed to any prior offenses committed by the defendant, which are added together to generate a criminal history score that places the defendant within a particular criminal history category. §§ 1B1.1(a)(6), 4A1.1. Together, the offense level and the criminal history category identify the applicable Guidelines range. § 1B1.1(a)(7).

B

The district court has the ultimate responsibility to ensure that the Guidelines range it considers is correct, and the "[f]ailure to calculate the correct Guidelines range constitutes procedural error." Peugh, 569 U.S., at 537, 133 S.Ct. 2072. Given the complexity of the calculation, however, district courts sometimes make mistakes. It is unsurprising, then, that "there will be instances when a district court's sentencing of a defendant within the framework of an incorrect Guidelines range goes unnoticed" by the parties as well, which may result in a defendant raising the error for the first time on appeal. Molina–Martinez, 578 U.S., at ––––, 136 S.Ct., at 1343. Those defendants are not entirely without recourse.

Federal Rule of Criminal Procedure 52(b) provides that "[a] plain error that affects substantial rights may be considered even though it was not brought to the [district] court's attention." In United States v. Olano, 507 U.S. 725, 113 S.Ct. 1770, 123 L.Ed.2d 508 (1993), the Court established three conditions that must be met before a court may consider exercising its discretion to correct the error. "First, there must be an error that has not been intentionally relinquished or abandoned. Second, the error must be plain—that is to say, clear or obvious. Third, the error must have affected the defendant's substantial rights." Molina–Martinez, 578 U.S., at ––––, 136 S.Ct., at 1343 (citations omitted). To satisfy this third condition, the defendant ordinarily must " ‘show a reasonable probability that, but for the error,’ the outcome of the proceeding would have been different." Ibid. (quoting United States v. Dominguez Benitez, 542 U.S. 74, 76, 82, 124 S.Ct. 2333, 159 L.Ed.2d 157 (2004) ). Once those three conditions have been met, "the court of appeals should exercise its discretion to correct the forfeited error if the error seriously affects the fairness, integrity or public reputation of judicial proceedings." Molina–Martinez, 578 U.S., at ––––, 136 S.Ct., at 1343 (internal quotation marks omitted). It is this last consideration, often called Olano 's fourth prong, that we are asked to clarify and apply in this case.

C

Petitioner Florencio Rosales–Mireles pleaded guilty to illegal reentry in violation of 8 U.S.C. §§ 1326(a), (b)(2). The Probation Office in its presentence investigation report mistakenly counted a 2009 state conviction of misdemeanor assault twice. This double counting resulted in a criminal history score of 13, which placed Rosales–Mireles in criminal history category VI. Combined with his offense level of 21, that yielded a Guidelines range of 77 to 96 months. Had the criminal history score been calculated correctly, Rosales–Mireles would have been in criminal history category V, and the resulting Guidelines range would have been 70 to 87 months. See USSG ch. 5, pt. A (sentencing table).

Rosales–Mireles did not object to the double-counting error before the District Court. Relying on the erroneous presentence investigation report, and after denying Rosales–Mireles' request for a downward departure, the District Court sentenced Rosales–Mireles to 78 months of imprisonment, one month above the lower end of the Guidelines range that everyone thought applied.

On appeal, Rosales–Mireles argued for the first time that his criminal history score and the resulting Guidelines range were incorrect because of the double counting of his 2009 conviction. Because he had not objected in the District Court, the Court of Appeals for the Fifth Circuit reviewed for plain error. 850 F.3d 246, 248 (2017).

Applying the Olano framework, the Fifth Circuit concluded that Rosales–Mireles had established that the Guidelines miscalculation constituted an error that was plain, satisfying Olano 's first two conditions. It also held that the error affected Rosales–Mireles' substantial rights, thus satisfying the third condition, because there was "a reasonable probability that he would have been subject to a different sentence but for the error." 850 F.3d, at 249. In reaching that conclusion, the Fifth Circuit rejected the Government's argument that Rosales–Mireles would have received the same sentence regardless of the Guidelines error, because the District Court had denied a downward departure "based, in part, on Rosales–Mireles' criminal history," which "erroneously included an extra conviction." Ibid.

The Fifth Circuit nevertheless declined to exercise its discretion to vacate and remand the case for resentencing because it concluded that Rosales–Mireles failed to establish that the error would seriously affect the fairness, integrity, or public reputation of judicial proceedings. In its view, "the types of errors that warrant reversal are ones that would shock the conscience of the common man, serve as a powerful indictment against our system of justice, or seriously call into question the competence or integrity of the district judge." Id., at 250 (internal quotation marks and alterations omitted). Because Rosales–Mireles' sentence of 78 months fell within the correct range of 70 to 87 months, the Fifth Circuit held that neither the error nor the resulting sentence "would shock the conscience." Ibid.

The Fifth Circuit's articulation of Olano 's fourth prong is out of step with the practice of other Circuits. We granted certiorari to resolve that conflict, 582 U.S. ––––, 138 S.Ct. 55, 198 L.Ed.2d 781 (2017), and now reverse.

A

Although " Rule 52(b) is permissive, not mandatory," Olano, 507 U.S., at 735, 113 S.Ct. 1770 it is well established that courts "should" correct a forfeited plain error that affects substantial rights "if the error ‘seriously affects the fairness, integrity or public reputation of judicial proceedings.’ " Id., at 736, 113 S.Ct. 1770 (quoting United States v. Atkinson, 297 U.S. 157, 160, 56 S.Ct. 391, 80 L.Ed. 555 (1936) ; alteration omitted); see also Molina–Martinez, 578 U.S., at –––– – ––––, 136 S.Ct., at 1342–1343. The Court in Olano rejected a narrower rule that would have called for relief only " ‘in those circumstances in which a miscarriage of justice would otherwise result,’ " that is to say, where a defendant is actually innocent. 507 U.S., at 736, 113 S.Ct. 1770 (quoting United States v. Young, 470 U.S. 1, 15, 105 S.Ct. 1038, 84 L.Ed.2d 1 (1985) ). By focusing instead on principles of fairness, integrity, and public reputation, the Court recognized a broader category of errors that warrant correction on plain-error review. See 507 U.S., at 736–737, 113 S.Ct. 1770.

Like the miscarriage-of-justice rule that the Court rejected in Olano, the Fifth Circuit's standard is unduly restrictive. To be sure, a conclusion that an error "shock[s] the conscience of the common man, serve[s] as a powerful indictment against our system of justice, or seriously call[s] into question the competence or integrity of the district judge," 850 F.3d, at 250 (internal quotation marks omitted), would demand an exercise of discretion to correct the error. Limiting relief only to those circumstances, however, too narrowly confines the extent of a court of appeals' discretion.

The "shock the conscience" standard typically is employed when determining whether governmental action violates due process rights under the Fifth and Fourteenth Amendments. See County of Sacramento v. Lewis, 523 U.S. 833, 847, n. 8, 118 S.Ct. 1708, 140 L.Ed.2d 1043 (1998) ("[I]n a due process challenge to executive action, the threshold question is whether the behavior of the governmental officer is so egregious, so outrageous, that it may fairly be said to shock the contemporary conscience"). This Court has said that the "shock the conscience" standard is satisfied where the conduct was "intended to injure in some way unjustifiable by any government interest," or in some circumstances if it resulted from deliberate indifference. Id., at 849–850, 118 S.Ct. 1708.

That standard is not reflected in Rule 52(b) itself, nor in how this Court has applied the plain-error doctrine. The Court repeatedly has reversed judgments for plain error on the basis of inadvertent or unintentional errors of the court or the parties below. See, e.g., Silber v. United

States, 370 U.S. 717, 717–718, 82 S.Ct. 1287, 8 L.Ed.2d 798 (1962) (per curiam ) (reversing judgment for plain error as a result of insufficient indictment); Brasfield v. United States, 272 U.S. 448, 449–450, 47 S.Ct. 135, 71 L.Ed. 345 (1926) (reversing judgment for plain error where the trial judge improperly inquired of a jury's numerical division); Clyatt v. United States, 197 U.S. 207, 222, 25 S.Ct. 429, 49 L.Ed. 726 (1905) (reversing judgment for plain error where the Government presented insufficient evidence to sustain conviction). The Court also "routinely remands" cases involving inadvertent or unintentional errors, including sentencing errors, for consideration of Olano 's fourth prong with the understanding that such errors may qualify for relief. Hicks v. United States, 582 U.S. ––––, ––––, 137 S.Ct. 2000, 2000–2001, 198 L.Ed.2d 718 (2017) (GORSUCH, J., concurring).

The Fifth Circuit's additional focus on errors that "serve as a powerful indictment against our system of justice, or seriously call into question the competence or integrity of the district judge," 850 F.3d, at 250 (internal quotation marks omitted), similarly alters the Rule 52(b) standard. The Court has never said that errors must amount to a "powerful indictment" of the system, a phrase which implies by its terms that the only errors worthy of correction are those that rise to the level of grossly serious misconduct. Similarly, the Fifth Circuit's emphasis on the "competence or integrity of the district judge" narrows Olano 's instruction that an error should be corrected if it seriously affects "judicial proceedings." In articulating such a high standard, the Fifth Circuit substantially changed Olano 's fourth prong.

B

The effect of the Fifth Circuit's heightened standard is especially pronounced in a case like this one. A plain Guidelines error that affects a defendant's substantial rights is precisely the type of error that ordinarily warrants relief under Rule 52(b).

In Molina–Martinez, the Court recognized that "[w]hen a defendant is sentenced under an incorrect Guidelines range—whether or not the defendant's ultimate sentence falls within the correct range—the error itself can, and most often will, be sufficient to show a reasonable probability of a different outcome absent the error." 578 U.S., at ––––, 136 S.Ct., at 1345. In other words, an error resulting in a higher range than the Guidelines provide usually establishes a reasonable probability that a defendant will serve a prison sentence that is more than "necessary" to fulfill the purposes of incarceration. 18 U.S.C. § 3553(a) ; Tapia, 564 U.S., at 325, 131 S.Ct. 2382. "To a prisoner," this prospect of additional "time behind bars is not some theoretical or mathematical concept." Barber v. Thomas, 560 U.S. 474, 504, 130 S.Ct. 2499, 177 L.Ed.2d 1 (2010) (KENNEDY, J., dissenting). "[A]ny amount of actual jail time" is significant, Glover v. United States, 531 U.S. 198, 203, 121 S.Ct. 696, 148 L.Ed.2d 604 (2001), and "ha[s] exceptionally severe consequences for the incarcerated individual [and] for society which bears the direct and indirect costs of incarceration," United States v. Jenkins, 854 F.3d 181, 192 (C.A.2 2017). The possibility of additional jail time thus warrants serious consideration in a determination whether to exercise discretion under Rule 52(b). It is crucial in maintaining public perception of fairness and integrity in the justice system that courts exhibit regard for fundamental rights and respect for prisoners "as people." T. Tyler, Why People Obey the Law 164 (2006). The risk of unnecessary deprivation of liberty particularly undermines the fairness, integrity, or public reputation of judicial proceedings in the context of a plain Guidelines error because of the role the district court plays in calculating the range and the relative ease of correcting the error. Unlike "case[s] where trial strategies, in retrospect, might be criticized for leading to a harsher sentence," Guidelines miscalculations ultimately result from judicial error. Glover, 531 U.S., at 204, 121 S.Ct. 696 ; see also Peugh, 569 U.S., at 537, 133 S.Ct. 2072. That was especially so here where the District Court's error in imposing Rosales–Mireles' sentence was based on a mistake made in the presentence investigation report by the Probation Office, which works on behalf of the District Court. Moreover, "a remand for resentencing, while not costless, does not invoke the same difficulties as a remand for retrial does." Molina–Martinez, 578 U.S., at ––––, 136 S.Ct., at 1348–1349 (internal quotation marks omitted). "A resentencing is a brief event, normally taking less than a day and requiring the attendance of only the defendant, counsel, and court personnel." United States v. Williams, 399 F.3d 450, 456 (C.A.2 2005).

Ensuring the accuracy of Guidelines determinations also serves the purpose of "providing certainty and fairness in sentencing" on a greater scale. 28 U.S.C. § 994(f) ; see also § 991(b)(1)(B) ; Booker, 543 U.S., at 264, 125 S.Ct. 738. The Guidelines assist federal courts across the country in achieving uniformity and proportionality in sentencing. See Rita, 551 U.S., at 349, 127 S.Ct. 2456. To realize those goals, it is important that sentencing proceedings actually reflect the nature of the offense and criminal history of the defendant, because the United States Sentencing Commission relies on data developed during sentencing proceedings, including information in the presentence investigation report, to determine whether revisions to the Guidelines are necessary. See id., at 350, 127 S.Ct. 2456. When sentences based on incorrect Guidelines ranges go uncorrected, the Commission's ability to make appropriate amendments is undermined.

In broad strokes, the public legitimacy of our justice system relies on procedures that are "neutral, accurate, consistent, trustworthy, and fair," and that "provide opportunities for error correction." Bowers & Robinson, Perceptions of Fairness and Justice: The Shared Aims and Occasional Conflicts of Legitimacy and Moral Credibility, 47 Wake Forest L. Rev. 211, 215–216 (2012). In considering claims like Rosales–Mireles', then, "what reasonable citizen wouldn't bear a rightly diminished view of the judicial process and its integrity if courts refused to correct obvious errors of their own devise that threaten to require individuals to linger longer in federal prison than the law demands?" United States v. Sabillon–Umana, 772 F.3d 1328, 1333–1334 (C.A.10 2014) (Gorsuch, J.). In the context of a plain Guidelines error that affects substantial rights, that diminished view of the proceedings ordinarily will satisfy Olano 's fourth prong, as it does in this case. As the Fifth Circuit itself concluded, there is a reasonable probability that, without correction of the Guidelines error, Rosales–Mireles will spend more time in prison than the District Court otherwise would have considered necessary. 850 F.3d, at 249. That error was based on a mistake by the Probation Office, a mistake that can be remedied through a relatively inexpensive resentencing proceeding.

Of course, any exercise of discretion at the fourth prong of Olano inherently requires "a case-specific and fact-intensive" inquiry. Puckett v. United States, 556 U.S. 129, 142, 129 S.Ct. 1423, 173 L.Ed.2d 266 (2009) ; see also Young, 470 U.S., at 16–17, n. 14, 105 S.Ct. 1038. There may be instances where countervailing factors satisfy the court of appeals that the fairness, integrity, and public reputation of the proceedings will be preserved absent correction. But on the facts of this case, there are no such factors.

III

The United States and the dissent agree with Rosales–Mireles that the Fifth Circuit's formulation of the standard for the exercise of discretion under Rule 52(b)"is an inaccurate description" of Olano 's fourth prong. Brief for United States 34; post, at 1911, n. 1 (opinion of THOMAS, J.) ("[T]he Fifth Circuit's standard is higher than the one articulated in this Court's precedents"). They nevertheless maintain that Rosales–Mireles is not entitled to relief. We are unpersuaded, though a few points merit brief discussion.

First, the United States and the dissent caution that a grant of relief in Rosales–Mireles' case and in others like his would be inconsistent with the Court's statements that discretion under Rule 52(b) should be exercised "sparingly," Jones v. United States, 527 U.S. 373, 389, 119 S.Ct. 2090, 144 L.Ed.2d 370 (1999), and reserved for "exceptional circumstances," Atkinson, 297 U.S., at 160, 56 S.Ct. 391. As an initial matter, Jones and the cases it relies on for the point that discretion should be exercised "sparingly" would have required additional jury proceedings on remand, either at resentencing or retrial. See 527 U.S., at 384, 389, 119 S.Ct. 2090 ; see also Young, 470 U.S. 1, 105 S.Ct. 1038, 84 L.Ed.2d 1 ; United States v. Frady, 456 U.S. 152, 102 S.Ct. 1584, 71 L.Ed.2d 816 (1982) ; Henderson v. Kibbe, 431 U.S. 145, 97 S.Ct. 1730, 52 L.Ed.2d 203 (1977). As we have explained, a decision remanding a case to the district court for resentencing on the basis of a Guidelines miscalculation is far less burdensome than a retrial, or other jury proceedings, and thus does not demand such a high degree of caution.In any event, the circumstances surrounding Rosales–Mireles' case are exceptional within the meaning of the Court's precedent on plain-error review, as they are reasonably likely to have resulted in a longer prison sentence than necessary and there are no countervailing factors that otherwise further the fairness, integrity, or public reputation of judicial proceedings. The fact that, as a result of the Court's holding, most defendants in Rosales–Mireles' situation will be eligible for relief under Rule 52(b) does not justify a decision that ignores the harmful effects of allowing the error to persist.

Second, the United States and the dissent assert that, because Rosales–Mireles' sentence falls within the corrected Guidelines range, the sentence is presumptively reasonable and "less likely to indicate a serious injury to the fairness, integrity, or public reputation of judicial proceedings." Brief for United States 20–21; see also post, at 1916. A substantive reasonableness determination, however, is an entirely separate inquiry from whether an error warrants correction under plain-error review.

Before a court of appeals can consider the substantive reasonableness of a sentence, "[i]t must first ensure that the district court committed no significant procedural error, such as failing to calculate (or improperly calculating) the Guidelines range." Gall, 552 U.S., at 51, 128 S.Ct. 586. This makes eminent sense, for the district court is charged in the first instance with determining whether, taking all sentencing factors into consideration, including the correct Guidelines range, a sentence is "sufficient, but not greater than necessary." 18 U.S.C. § 3553(a). If the district court is unable properly to undertake that inquiry because of an error in the Guidelines range, the resulting sentence no longer bears the reliability that would support a "presumption of reasonableness" on review. See Gall, 552 U.S., at 51, 128 S.Ct. 586. Likewise, regardless of its ultimate reasonableness, a sentence that lacks reliability because of unjust procedures may well undermine public perception of the proceedings. See Hollander–Blumoff, The Psychology of Procedural Justice in the Federal Courts, 63 Hastings L.J. 127, 132–134 (2011) (compilation of psychology research showing that the fairness of procedures influences perceptions of outcomes). The mere fact that Rosales–Mireles' sentence falls within the corrected Guidelines range does not preserve the fairness, integrity, or public reputation of the proceedings.

Third, the United States and the dissent contend that our decision "creates the very opportunity for ‘sandbagging’ that Rule 52(b) is supposed to prevent." Post, at 1903; Brief for United States 17–18, 27. But that concern fails to account for the realities at play in sentencing proceedings. As this Court repeatedly has explained, "the Guidelines are ‘the starting point for every sentencing calculation in the federal system,’ " Hughes v. United States, 584 U.S. ––––, ––––, 138 S.Ct. 1765, ––––, –––L.Ed.2d ––––, 2018 WL 2465187 (2018) (slip op., at 9) (quoting Peugh, 569 U.S., at 542, 133 S.Ct. 2072 ). It is hard to imagine that defense counsel would "deliberately forgo objection now " to a plain Guidelines error that would subject her client to a higher Guidelines range, "because [counsel] perceives some slightly expanded chance to argue for ‘plain error’ later ." Henderson v. United States, 568 U.S. 266, 276, 133 S.Ct. 1121, 185 L.Ed.2d 85 (2013) (emphasis in original). Even setting aside the conflict such a strategy would create with defense counsel's ethical obligations to represent her client vigorously and her duty of candor toward the court, any benefit from such a strategy is highly speculative. There is no guarantee that a court of appeals would agree to a remand, and no basis to believe that a district court would impose a lower sentence upon resentencing than the court would have imposed at the original sentencing proceedings had it been aware of the plain Guidelines error.

IV

For the foregoing reasons, we conclude that the Fifth Circuit abused its discretion in applying an unduly burdensome articulation of Olano 's fourth prong and declining to remand Rosales–Mireles' case for resentencing. In the ordinary case, as here, the failure to correct a plain Guidelines error that affects a defendant's substantial rights will seriously affect the fairness, integrity, and public reputation of judicial proceedings. The judgment of the Court of Appeals is therefore reversed, and the case is remanded for further proceedings consistent with this opinion.

It is so ordered.

Justice THOMAS, with whom Justice ALITO joins, dissenting.

The Court holds that, "in the ordinary case," a miscalculation of the advisory Sentencing Guidelines range will "seriously affect the fairness, integrity, or public reputation of judicial proceedings." Ante, at 1903. In other words, a defendant who does not alert the district court to a plain miscalculation of his Guidelines range—and is not happy with the sentence he receives—can raise the Guidelines error for the first time on appeal and ordinarily get another shot at a more favorable sentence. The Court's decision goes far beyond what was necessary to answer the question presented. And it contravenes long-established principles of plain-error review. I respectfully dissent.

I

Under Federal Rule of Criminal Procedure 52(b), "[a] plain error that affects substantial rights may be considered even though it was not brought to the court's attention." (Emphasis added.) The "point of the plain-error rule" is to "requir[e] defense counsel to be on his toes." United States v. Vonn, 535 U.S. 55, 73, 122 S.Ct. 1043, 152 L.Ed.2d 90 (2002). Its demanding standard is meant to "encourage timely objections and reduce wasteful reversals by demanding strenuous exertion to get relief for unpreserved error." United States v. Dominguez Benitez, 542 U.S. 74, 82, 124 S.Ct. 2333, 159 L.Ed.2d 157 (2004). If the standard were not stringent, there would be nothing "prevent [ing] a litigant from ‘ "sandbagging" ’ the court—remaining silent about his objection and belatedly raising the error only if the case does not conclude in his favor." Puckett v. United States, 556 U.S. 129, 134, 129 S.Ct. 1423, 173 L.Ed.2d 266 (2009). Satisfying the plain-error standard "is difficult, ‘as it should be.’ " Id., at 135, 129 S.Ct. 1423.

This Court has held that Rule 52(b) is satisfied only when four requirements are met: "(1) there is ‘an error,’ (2) the error is ‘plain,’ " "(3) the error ‘affect[s] substantial rights,’ " and "(4) ... ‘the error "seriously affect[s] the fairness, integrity or public reputation of judicial proceedings." ’ " Henderson v. United States, 568 U.S. 266, 272, 133 S.Ct. 1121, 185 L.Ed.2d 85 (2013). The fourth requirement—the one at issue here—is discretionary. Ibid. It should "be applied on a case-specific and fact-intensive basis." Puckett, supra, at 142, 129 S.Ct. 1423. And it cannot be satisfied by "a plain error affecting substantial rights ..., without more, ... for otherwise the discretion afforded by Rule 52(b) would be illusory." United States v. Olano, 507 U.S. 725, 737, 113 S.Ct. 1770, 123 L.Ed.2d 508 (1993). Instead, "only ‘particularly egregious errors' " will meet the fourth prong's rigorous standard. United States v. Young, 470 U.S. 1, 15, 105 S.Ct. 1038, 84 L.Ed.2d 1 (1985) (quoting United States v. Frady, 456 U.S. 152, 163, 102 S.Ct. 1584, 71 L.Ed.2d 816 (1982) ); see also United States v. Atkinson, 297 U.S. 157, 160, 56 S.Ct. 391, 80 L.Ed. 555 (1936) (explaining that courts should provide relief under plain-error review only in "exceptional circumstances").

II

The Court holds that Guidelines errors will "ordinar[ily]" satisfy the fourth prong of plain-error review. Ante, at 1911. This result contravenes several established principles from our precedents.

To begin, the Court's decision is at odds with the principle that the fourth prong of plain-error review "be applied on a case-specific and fact-intensive basis." Puckett, supra, at 142, 129 S.Ct. 1423. By holding that a Guidelines error "ordinarily will satisfy [the] fourth prong" absent "countervailing factors," ante, at 1908, the Court creates what is essentially a rebuttable presumption that plain Guidelines errors satisfy Rule 52(b). And, based on the Court's application of it today, this presumption certainly must be difficult to rebut. The Court matter-of-factly asserts, in a single sentence with no analysis, that "there are no [countervailing] factors" in this case that counsel in favor of affirmance. Ante, at 1908. It does so without even discussing the particular details of the defendant's crime, what happened at his sentencing, the reasoning that the District Court employed, the difference between the defendant's calculated Guidelines range and the correct one, or where his sentence fell relative to the correct Guidelines range. This approach is neither "case-specific" nor "fact-intensive." Puckett, supra, at 142, 129 S.Ct. 1423. The Court candidly admits as much. See ante, at 1908, n. 4. But this is exactly the kind of " ‘per se approach to plain-error review’ " that we have consistently rejected. Puckett, supra, at 142, 129 S.Ct. 1423.

The Court's rebuttable presumption also renders the fourth prong of plain-error review "illusory" in most Guidelines cases. Olano, supra, at 737, 113 S.Ct. 1770. The Court expressly states that Guidelines errors will satisfy the fourth prong in "the ordinary case." Ante, at 1911. But this Court has repeatedly held that the fourth prong limits courts' discretion to "correct [ing] only ‘particularly egregious errors.’ " Young, supra, at 15, 105 S.Ct. 1038. Because Rule 52(b)" ‘is not a run-of-the-mill remedy,’ " Frady, supra, at 163, n. 14, 102 S.Ct. 1584 relief should be granted "sparingly" in " ‘the rare case,’ " Jones v. United States, 527 U.S. 373, 389, 119 S.Ct. 2090, 144 L.Ed.2d 370 (1999), and only in "exceptional circumstances," Atkinson, supra, at 160, 56 S.Ct. 391. Today's decision turns that principle on its head by making relief available "in the ordinary case." Ante, at 1903.

The Court asserts that relief under plain-error review need not be exceptional or rare when a remand would not require "additional jury proceedings." Ante, at 1909. But that distinction has no basis in the text of Rule 52(b) or this Court's precedents. The only Rule 52(b) precedent that the Court cites for this assertion is Molina–Martinez v. United States, 578 U.S. ––––, ––––, 136 S.Ct. 1338, 1348–1349, 194 L.Ed.2d 444 (2016). See ante, at 1907. That decision rejected the Fifth Circuit's categorical rule requiring defendants to present "additional evidence" (beyond the Guidelines error itself) to prove prejudice under the third prong of plain-error review. See 578 U.S., at –––– – ––––, 136 S.Ct., at 1345–1346. In dicta it suggested that, "in the ordinary case," the Guidelines error would be enough to satisfy the third prong's requirement that the error affect substantial rights. Id., at ––––, 136 S.Ct., at 1349. And it rebuffed the Government's pragmatic "concern over the judicial resources needed" if Guidelines errors usually satisfy the third prong of plain-error review. Id., at ––––, 136 S.Ct., at 1348. But Molina–Martinez did not discuss the fourth prong of plain-error review, which is at issue here and is an independent requirement, see Olano, supra, at 737, 113 S.Ct. 1770. Nor did it relax the plain-error standard whenever reversal would not require "additional jury proceedings." Ante, at 1909. Thus, Molina–Martinez gives no support to the Court's innovation.

Additionally, the Court's encouragement of remands based on ordinary Guidelines errors undermines "the policies that underpin Rule 52(b)." Dominguez Benitez, 542 U.S., at 82, 124 S.Ct. 2333. As explained, the plain-error standard encourages defendants to make timely objections in order to avoid sandbagging and to prevent wasteful reversals and remands. After today, however, most defendants who fail to object to a Guidelines error will be in virtually the same position as those who do. Today's decision, especially when combined with Molina–Martinez, means that plain Guidelines errors will satisfy Rule 52(b) in all but the unusual case. That creates the very opportunity for "sandbagging" that Rule 52(b) is supposed to prevent, Puckett, 556 U.S., at 134, 129 S.Ct. 1423 (internal quotation marks omitted), by allowing a defendant who is aware of a mistake in the presentence report to "simply relax and wait to see if the sentence later str[ikes] him as satisfactory," Vonn, 535 U.S., at 73, 122 S.Ct. 1043. Oddly, defendants who do not object to a Guidelines error could be in a better position than ones who do. An objection would give the district court a chance to explain why it would "arrive at the same sentencing conclusion" even if the defendant was correct about an alleged Guidelines error, which would "mak[e] clear" that the Guidelines error did not "adversely affect the defendant's ultimate sentence." United States v. Sabillon–Umana, 772 F.3d 1328, 1334 (C.A.10 2014). Today's decision thus inverts Rule 52(b) by giving defendants an incentive to withhold timely objections and " ‘game’ the system." Puckett, supra, at 140, 129 S.Ct. 1423.

III

Even if it were appropriate to create rebuttable presumptions under the fourth prong of plain-error review, the Court is wrong to conclude that the "ordinary" Guidelines error will "seriously affect the fairness, integrity, or public reputation of judicial proceedings." Ante, at 1903. Whether a district court's failure to correctly calculate the advisory Guidelines range satisfies the fourth prong of plain-error review will depend on the circumstances of each case. And the circumstances of this case prove the folly of the Court's presumption.

A

The Court asserts that plain Guidelines errors must ordinarily be corrected to ensure that defendants do not "linger longer in federal prison than the law demands." Ante, at 1908 (internal quotation marks omitted). But the Guidelines are not "law." They neither "define criminal offenses" nor "fix the permissible sentences for criminal offenses." Beckles v. United States, 580 U.S. ––––, ––––, 137 S.Ct. 886, 892, 197 L.Ed.2d 145 (2017) (emphasis deleted). Instead, they are purely "advisory" and "merely guide the district courts' discretion." Id., at ––––, 137 S.Ct., at 894. They provide advice about what sentencing range the Sentencing Commission believes is appropriate, "but they ‘do not constrain’ " district courts. Ibid. Accordingly, district courts are free to disagree with the Guidelines range, for reasons as simple as a policy disagreement with the Sentencing Commission. See Pepper v. United States, 562 U.S. 476, 501, 131 S.Ct. 1229, 179 L.Ed.2d 196 (2011) ; 18 U.S.C. § 3661. In fact, district courts commit reversible error if they "trea [t] the Guidelines as mandatory." Gall v. United States, 552 U.S. 38, 51, 128 S.Ct. 586, 169 L.Ed.2d 445 (2007). Although the Guidelines range is one of the factors that courts must consider at sentencing, 18 U.S.C. § 3553(a), judges need not give the Guidelines range any particular weight. The only thing that "the law demands" is that a defendant's sentence be substantively reasonable and within the applicable statutory range. See Jones v. United States, 577 U.S. ––––, –––– – ––––, 135 S.Ct. 8, 8–9, 190 L.Ed.2d 279 (2014) (Scalia, J., dissenting from denial of certiorari); Kimbrough v. United States, 552 U.S. 85, 113–114, 128 S.Ct. 558, 169 L.Ed.2d 481 (2007) (Scalia, J., concurring).

The Court also justifies its presumption by repeatedly stressing the importance of procedural rules to the public's perception of judicial proceedings. See ante, at 1908 ("[T]he public legitimacy of our justice system relies on procedures"); ante, at 1910 ("[U]njust procedures may well undermine public perception of [sentencing] proceedings"). It even cites a hodgepodge of psychological studies on procedural justice. Ante, at 1910 (citing Hollander–Blumoff, The Psychology of Procedural Justice in the Federal Courts, 63 Hastings L.J. 127, 132–134 (2011) (Hollander–Blumoff)).

Putting aside the obvious problems with this research, the Court contradicts our precedents by suggesting that adhering to procedure has prime importance for purposes of the fourth prong. This Court has repeatedly concluded that purely procedural errors—ones that likely did not affect the substantive outcome—do not satisfy the fourth prong of plain-error review. In Johnson v. United States, 520 U.S. 461, 117 S.Ct. 1544, 137 L.Ed.2d 718 (1997), for example, the District Court failed to submit a materiality element to the jury, but this Court found that the fourth prong of plain-error review was not satisfied because "the evidence supporting materiality was ‘overwhelming.’ " Id., at 470, 117 S.Ct. 1544. Reversal based on errors that have no actual " ‘effect on the judgment,’ " this Court explained, " ‘encourages litigants to abuse the judicial process and bestirs the public to ridicule it.’ " Ibid. (quoting R. Traynor, The Riddle of Harmless Error 50 (1970)). Similarly, in United States v. Cotton, 535 U.S. 625, 122 S.Ct. 1781, 152 L.Ed.2d 860 (2002), the indictment failed to allege a fact that increased the statutory maximum, but the evidence of that fact "was ‘overwhelming’ and ‘essentially uncontroverted.’ " Id., at 633, 122 S.Ct. 1781. This Court held that reversing a defendant's sentence based on such a technicality would be "[t]he real threat ... to the ‘fairness, integrity, and public reputation of judicial proceedings.’ " Id., at 634, 122 S.Ct. 1781. And in United States v. Marcus, 560 U.S. 258, 130 S.Ct. 2159, 176 L.Ed.2d 1012 (2010), the Second Circuit had held that an ex post facto error automatically satisfies the plain-error standard, " ‘no matter how unlikely’ " it was that the jury actually convicted the defendant based on conduct that predated the statute of conviction. Id., at 261, 130 S.Ct. 2159 (emphasis deleted). In reversing that decision, this Court emphasized that, "in most circumstances, an error that does not affect the jury's verdict does not significantly impugn the ‘fairness,’ ‘integrity,’ or ‘public reputation’ of the judicial process." Id., at 265–266, 130 S.Ct. 2159. Thus, the Court is mistaken when it asserts that, because Guidelines errors are procedural mistakes, they are particularly likely to implicate the fourth prong of plain error.

B

While the Court holds that the ordinary Guidelines error will satisfy the fourth prong of plain-error review, it admits that there can be "instances where countervailing factors" preclude defendants from satisfying the fourth prong. Ante, at 1908. Because the Court does not question our existing plain-error precedents, see ante, at 1909, the burden presumably remains on defendants to establish that there are no such countervailing factors, and to persuade the appellate court that any countervailing factor identified by the Government is insufficient. See Vonn, 535 U.S., at 63, 122 S.Ct. 1043 ("[A] defendant has the further burden to persuade the court that the error seriously affect[ed] the fairness, integrity or public reputation of judicial proceedings" (internal quotation marks omitted)); Dominguez Benitez, 542 U.S., at 82, 124 S.Ct. 2333 ("[T]he burden of establishing entitlement to relief for plain error is on the defendant claiming it"). But the Court does not explain what the defendant in this case has done to satisfy his burden.

If this case is an ordinary one, it highlights the folly of the Court's new rebuttable presumption. Petitioner Florencio Rosales–Mireles has a penchant for entering this country illegally and committing violent crimes—especially against women. A Mexican citizen, Rosales–Mireles entered the United States illegally in 1997. In 2002, he was convicted of assault for throwing his girlfriend to the floor of their apartment and dragging her outside by her hair. In 2009, he was convicted of aggravated assault with serious bodily injury and assault causing bodily injury to a family member. His convictions stemmed from an altercation in which he attempted to stab one man and did stab another—once in the shoulder and twice in the chest. In January 2010, Rosales–Mireles was removed to Mexico. But that same month he reentered the United States illegally. In 2015, he was convicted in Texas state court of assaulting his wife and 14–year–old son. During the altercation, Rosales–Mireles grabbed his wife by the hair and punched her in the face repeatedly.

Most recently, Rosales–Mireles pleaded guilty to illegal reentry. See 8 U.S.C. §§ 1326(a), (b)(2). The District Court sentenced him to 78 months in prison, which was within the Guidelines range he argued for on appeal. See ante, at 1904 – 1905. In choosing that sentence, the District Court emphasized that it was "the second time he's come to the courts for being here illegally"; that he had "attempted to hide in the United States with multiple aliases, birth dates, [and] Social Security numbers"; and that his "assaultive behavior" spanned from "at least ... 2001 to 2015." App. 20.

The sentence that Rosales–Mireles received was not only within both the improperly and properly calculated Guidelines ranges but also in the bottom half of both possible ranges. See ante, at 1904 – 1905. If the District Court had used the proper Guidelines range at his initial sentencing, then the sentence that it ultimately gave Rosales–Mireles would have been presumptively reasonable on appeal. See 850 F.3d 246, 250 (C.A.5 2017) ; Rita v. United States, 551 U.S. 338, 347, 127 S.Ct. 2456, 168 L.Ed.2d 203 (2007). And the Fifth Circuit determined that his sentence was in fact reasonable. See 850 F.3d, at 250–251. Leaving that reasonable sentence in place would not " ‘seriously affect the fairness, integrity, or public reputation of judicial proceedings.’ " Young, 470 U.S., at 15, 105 S.Ct. 1038. A sentence that is substantively reasonable is hardly the kind of "particularly egregious erro[r]" that warrants plain-error relief. Frady, 456 U.S., at 163, 102 S.Ct. 1584.

* * *

Rule 52(b) strikes a "careful balance ... between judicial efficiency and the redress of injustice." Puckett, 556 U.S., at 135, 129 S.Ct. 1423. Because today's decision upsets that balance for scores of cases involving Guidelines errors, I respectfully dissent.
