560 U.S. 474
BARBER etal. v . THOMAS, WARDEN
certiorari to the united states court of appeals for the ninth circuit
The federal sentencing statute at issue provides that a prisoner serving a term of imprisonment of more than 1 year may receive credit toward the service of [that] sentence of up to 54 days at the end of each year subject to the Bureau of Prisons (BOP) determination that, during that year, the prisoner has behaved in an exemplary fashion. 18 U.S.C. 3624(b)(1). Credit for the last year or portion of a year of the term of imprisonment [is] prorated . Ibid. The BOP applies this statute using a methodology that awards 54 days of credit at the end of each year the prisoner serves and sets those days to the side. When the difference between the time remaining in the sentence and the amount of accumulated credit is less than one year, the BOP awards a prorated amount of credit for that final year proportional to the awards in other years.
Petitioners claim that the BOPs calculation method is unlawful because 3624(b)(1) requires a calculation based on the length of the term of imprisonment imposed by the sentencing judge, not the length of time that the prisoner actually serves. The District Court rejected this challenge in each of petitioners cases, and the Ninth Circuit affirmed.
Held: Because the BOPs method for calculating good time credit reflects the most natural reading of the statute, it is lawful. Pp.517.
(a)The statutes language and purpose, taken together, support the BOPs method. That method tracks 3624(b)s language by providing a prisoner a maximum credit of 54 days for each full year of imprisonment and a proportionally adjusted amount of credit for any additional time served that is less than a full year. As 3624(b) directs, the BOP awards the credit at the end of each year of imprisonment. Petitioners approach cannot be reconciled with the statute. Because it awards credit for the sentence imposed, regardless of how much time is actually served, a prisoner could receive credit for a year that he does not spend in prison. Moreover the calculation of credit for such a year would not be made at the end of that year. Nor could the BOP determine whether the prisoner had exemplary behavior during that year. This language did not find its way into the statute by accident. The differences between the prior provision (repealed in 1984)which granted the prisoner a deduction at the outset of his sentence, subject to forfeiture for breaking prison rulesand the present statuteunder which credit is earned at the end of the year based on an evaluation of behavior during that yearshow an intent to move from a prospective entitlement to a retrospective award. The BOPs method also furthers the basic purpose of the statute. Section 3624 was part of the comprehensive Sentencing Reform Act of 1984, which sought to achieve both increased sentencing uniformity and greater honesty by mak[ing] all sentences basically determinate. Mistretta v. United States , 488 U.S. 361. Thereafter, the sentence the judge imposed would be the one the offender actually served, with a sole statutory exception for good time credits. Ibid. Section 3624(b) states the reason for the exception: to provide an incentive for prisoners to compl[y] with institutional disciplinary regulations. The exception is limited and tailored to its purposecredit is earned at the end of the year after compliance with institutional rules is demonstrated and thereby rewards and reinforces a readily identifiable period of good behavior. The BOPs approach furthers 3624s objectives by tying the award directly to good behavior during the preceding year. In contrast, petitioners approach would allow a prisoner to earn credit for both the portion of his sentence that he served and the portion offset with earned credit, which would loosen the statutes connection between good behavior and the good time award. Pp.58.
(b)Arguments to the contrary are unconvincing. Context indicates that the phrase term of imprisonment as used in the portion of 3624(b) at issue here refers to prison time actually served not, as petitioners contend, to the sentence imposed by the judge. Petitioners reliance on legislative history is misplaced. A U.S. Sentencing Commission Supplementary Report is not helpful to them either, because there is no indication that the Commission, in that report or in the Guidelines themselves, considered or referred to the particular question whether to base good time credit on time served or the sentence imposed. Nor, in light of the statutes text, structure, history, and purpose, is this a case in which there is a grievous ambiguity or uncertainty in the statute, Muscarello v. United States , 524 U.S. 125, permitting application of the rule of lenity. Because the BOPs calculation system applies the statute as its language is most naturally read, and in accordance with the statutes basic purpose, this Court need not determine the extent to which Congress has granted the BOP authority to interpret the statute more broadly, or differently than it has done here. Cf. Chevron U.S.A. Inc. v. Natural Resources Defense Council, Inc. , 467 U.S. 837. And because the BOPs approach reflects the statutes most natural reading and is the most consistent with its purpose, it is also preferable to the dissents alternative interpretation. Pp.817.

MICHAEL GARY BARBER, et al. , PETITIONERS v.<linebreak> J. E. THOMAS, WARDEN
on writ of certiorari to the united states court of appeals for the ninth circuit
Justice Kennedy , with whom Justice Stevens and Justice Ginsburg join, dissenting.
The Court has interpreted a federal sentencing statute in a manner that disadvantages almost 200,000 federal prisoners. See Pet. for Cert. 11, and n. 2. It adopts this reading despite the existence of an alternative interpretation that is more consistent with the statutes text. Absent a clear congressional directive, the statute ought not to be read as the Court reads it. For the Courts interpretationan interpretation that in my submission is quite incorrectimposes tens of thousands of years of additional prison time on federal prisoners according to a mathematical formula they will be unable to understand. And if the only way to call attention to the human implications of this case is to speak in terms of economics, then it should be noted that the Courts interpretation comes at a cost to the taxpayers of untold millions of dollars. See id., at 11. The interpretation the Court adopts, moreover, will be devastating to the prisoners who have behaved the best and will undermine the purpose of the statute. These considerations, and those stated below, require this respectful dissent.
The federal sentencing statute at issue here provides:
[A] prisoner who is serving a term of imprisonment of more than 1 year[,] other than a term of imprisonment for the duration of the prisoners life, may receive credit toward the service of the prisoners sentence, beyond the time served, of up to 54 days at the end of each year of the prisoners term of imprisonment , beginning at the end of the first year of the term, subject to determination by the Bureau of Prisons that, during that year, the prisoner has displayed exemplary compliance with institutional disciplinary regulations. [C]redit for the last year or portion of a year of the term of imprisonment shall be prorated and credited within the last six weeks of the sentence. 18 U.S.C. 3624(b)(1) (emphasis added).
According to the Court, the phrase term of imprisonment must mean time actually served the third time that it appears in this particular subsection. But the Court gives the phrase a different interpretation the first two times it is used in the very same sentence. This in itself indicates that something is quite wrong here.
Petitioners invite the Court to read term of imprisonment to mean the sentence imposed. This, too, seems unworkable. And it can be acknowledged that the Courts rejection of this interpretation is correct.
The choice, however, is not just between the Courts reading and that offered by petitioners. There is a third possibility, one more consistent with the statute than either of these two alternatives.
A fair reading of the statute, and a necessary reading to accomplish its purpose best, is to interpret the phrase term of imprisonment to refer to the span of time that a prisoner must account for in order to obtain release. The length of the term is set at the outset by the criminal sentence imposed. The prisoner earns release when that term has been fully completed. Most of the term will be satisfied through time spent behind bars. Assuming the prisoner is well behaved, however, he may earn good time credits along the way; and those credits may substitute for actual prison time. Each year of the term comprises a full 365 days, which must be accounted for through a combination of prison time and credits. Thus conceived, a prisoners term is the administrative period along which progress toward eventual freedom is marked.
Consider the Courts example of a prisoner subject to a ten-year sentence. See ante , at 24. The sentence is divided into ten 365-day segments. Each segment constitutes a year of the term. The prisoner will spend the first 365 days behind bars. In the statutes words, he has reached the end of the first year of the term. Now is the time for credit to be awarded, and he may receive up to 54 days if sufficiently well behaved. Because he has already completed a full year of his term, those credits go toward completion of the next year. If, based on good behavior, he has earned the maximum of 54 days, he would need another 311 days behind bars before the second year of his term of imprisonment is at an end (because 54 + 311 = 365). If he has earned fewer than 54 days, a longer incarceration will be required to reach 365. Regardless, once the prisoner reaches the end of the second year of his term, he will again be eligible to receive good time credits.
This process repeats itself for the third year of the term, and so on. In the final year of his term (in this example, the tenth segment into which his term has been divided), the prisoner will receive credit in a prorated amount, to be awarded within the last six weeks of the sentence. This ensures that the prisoner does not reach the end of year ten, only to find that he has just earned 54 days of credit he no longer needs.
The controlling rule is that each year of the prisoners termeach of the ten administrative segmentscomprises 365 days that must be completed through a combination of service and credits. By combining actual prison time with the credits he has earned, a prisoner may complete a particular year of his term in less than 365 calendar days. As a result, credits may enable a well-behaved prisoner to complete his ten-year sentence before ten calendar years have elapsed. For a ten-year (3,650-day) sentence, a prisoner will serve 3,117 days behind bars if he earns a maximum of approximately 533 credits. This is 63 more days of credit than under the Courts readingmore than 6 additional credit days for every year of the sentence imposed.
Reading term of imprisonment this way is consistent with all parts of the statute. The prisoner receives his credit at the end of each year of [his] term of imprisonment, a process that begin[s] at the end of the first year of the term. Credit is only awarded if the prisoner has proven well behaved during that year. This interpretation fulfills the objective of 3624rewarding a prisoner for exemplary conduct during the preceding year. See ante , at 8.
This approach also has a textual integrity that the Courts reading does not: It gives term of imprisonment the same meaning each time it is used by the statute. Every time it appears in 3624(b)(1), term of imprisonment refers to the administrative period that a prisoner must complete in order to earn his freedom. The Court, by contrast, would read this phrase to mean time actually served the third time it is used, but the sentence imposed the first two times it is used (a prisoner who is serving a term of imprisonment of more than 1 year[,] other than a term of imprisonment for the duration of the prisoners life). See ante , at 89. The Courts interpretation thus runs afoul of the presumption that a given term is used to mean the same thing throughout a statute. Ante , at 9 (quoting Brown v. Gardner , 513 U.S. 115, 118 (1994) ). The inconsistency here is particularly egregious because all three uses appear in the same sentence. See id., at 118 ([The] presumption [is] surely at its most vigorous when a term is repeated within a given sentence).
The Court responds by noting another part of the statute, a provision stating that prisoners shall receive clothing, money, and transportation [u]pon the release of [the] prisoner on the expiration of the prisoners term of imprisonment. 3624(d). A prisoner is released at the end of his actual time behind bars, says the Court, and so term of imprisonment must here refer to time actually served. Yet release also comes at the end of a prisoners term in the sense described abovethat is, when the balance of the sentence has been reduced to zero through a combination of prison time and good time credits. Indeed, this administrative use of the phrase fits well with the word expiration, which in its most natural sense in this context refers to the close of a formal accounting period. See Blacks Law Dictionary 619 (8th ed. 2004) (A coming to an end; esp., a formal termination on a closing date). By contrast, it is awkward at best to say, as the Court would have it, that a prisoners actual time behind bars is something that expires.
The Courts approach produces yet another oddity. The statute requires that prorated credit be awarded for the last year or portion of a year of the term of imprisonment. One might naturally assume that the last year of a ten-year term would be year ten. That is how things work under the approach described above, in which a ten-year sentence is subdivided into ten administrative segments.
But under the Courts reading, a prisoner serving a ten-year sentence will never reach year ten of his term; year ten simply does not exist. According to the Court, year nine is the final year, and even year nine is not a full year: It lasts no more than 298 days. Ante , at 3. If this sounds confusing, it will be all the more so to the prisoner who has just received his sentence and turns to the statute books to figure out when to expect his freedom.
The Court does not even attempt to defend these flaws. Instead, it points to four supposed defects in the approach described above. None withstands examination.
First, the Court notes that the statute requires the release of a prisoner upon the expiration of the prisoners term of imprisonment, less any time credited for good behavior. Ante , at 15 (quoting 3624(a)). But if term of imprisonment truly refers to the entire span that a prisoner must complete to earn his freedoma period that accounts both for actual time and for good time creditsthen why would the less any time credited language be appropriate? The answer is that this provisionwhich appears at the very beginning of the section entitled Release of a prisonerannounces to a prisoner when release may be expected: when the prisoners term expires, taking into account credit days as provided in subsection (b). 3624(a) (bold face deleted). This use of language is common. A debtor who says I will write a check for what I owe you, less what you owe me is simply saying I will pay what I owe, taking into account your debts to me. Perhaps the same meaning could have been conveyed using different words, but this is hardly probative.
Second, the Court alleges that the above approach conflicts with the statutes requirement that credit be awarded at the end of each year based upon behavior during that year. After all, if a year of the term can be satisfied in part through credit, then it may last less than a full calendar year. Yet the statute does not require that credit be awarded at the end of a calendar year for good behavior during a calendar year. What it requires is that credit be awarded at the end of each year of the prisoners term of imprisonment for good behavior during that year. And this is precisely what the above approach does.
Third, the Court frets that, under the approach above, prisoners will earn credit at different rates during a single sentence. It admonishes that [t]he use of different rates finds no support in the statute. Ante , at 16. This response is telling. The statute, in fact, prescribes no particular rateand certainly no formula based on a rateexcept as embodied in one clear directive: Prisoners are eligible to earn up to 54 days at the end of each year of the prisoners term of imprisonment. As to that command, the above approach is perfectly faithful.
Fourth, the Court suggests that the above approach causes credit to vest immediately, contrary to the statute. Again, this is not true. As per the statute, credit only vests on the date the prisoner is released from custody, 3624(b)(2), meaning that it can be revoked at any time before that date. This gives prisoners approaching their release date an extra incentive to behave.
As a fallback, the Court wonders what would happen if a prisoner misbehaved on the final day of his ten-year sentence. Would the Bureau of Prisons (BOP) be forced to retroactively adjust the duration of all of his [term years] to 365 days? Ante , at 17. The answer is what one might suppose: A prisoner whose credits are revoked will find himself precisely where he would have been if those credits had never been earned. All years of the term remain 365 days, as they always have. But a misbehaving prisoner who had formerly earned, say, 500 credits will find himself without the benefit of those 500 days. That will leave him with more of his term to complete500 days more, to be precise. If he behaves well again, he can resume earning credit for the remainder of his term, but he has lost the opportunity to earn credits for any prior years. See 3624(b)(1). This is not at all confusing for a prisoner; and certainly it is as straightforward, if not more so, than the Courts approach. The Courts view causes a prisoners term of imprisonment to shrink over time according to an algebraic formula, only to expand again if he misbehaves.
Finally, the Court speculates that BOP might find the above approach difficult to administer. The Court identifies no basis for this claim, nor does one exist. The information used to calculate a prisoners term under the above approach is the same as it is under the Courts approach. True, a prisoner may become eligible to be awarded credit on different calendar days during the course of his term. But under the Courts approach, this also happens when awarding credit in the final year. And, it goes without saying, federal prisoners begin their incarceration on different calendar days anyway, so that under any approach, BOP will be forced to evaluate prisoners throughout the calendar year.
The Courts reading of 3624(b)(1), therefore, is less consistent with the text than the reading explained above. But even if these interpretations were in equipoise, under any fair application the rule of lenity should tip the balance in petitioners favor. When a penal statute is susceptible of two interpretations, the one more favorable to the defendant must be chosen unless text, structure, and history establish that the [harsher] position is unambiguously correct. United States v. Granderson , 511 U.S. 39, 54 (1994) . Resolving ambiguity in favor of lenity ensures that statutes provide fair warning[,] in language that the common world will understand, of what the law intends to do if a certain line is passed. United States v. Bass , 404 U.S. 336, 348 (1971) (internal quotation marks omitted). The rule thus applies not only to interpretations of the substantive ambit of criminal prohibitions, but also to the penalties they impose. Bifulco v. United States , 447 U.S. 381, 387 (1980) .
The Court assumes without deciding that 3624(b) is penal in nature. See ante , at 13. No assumption is necessary: The statutory provision awarding good time credits in fact is one determinant of [a] prison term, so that a prisoners effective sentence is altered once this determinant is changed. Weaver v. Graham , 450 U.S. 24, 32 (1981) . In Weaver , the Court considered whether an amendment to Floridas statutory formula for calculating good time credits implicated the ExPost Facto Clause. The Court concluded that it did, as the new statute substantially alter[ed] the consequences attached to a crime already completed, and therefore change[d] the quantum of punishment. Id., at 33 (quoting Dobbert v. Florida , 432 U.S. 282, 294 (1977) ). For the same reason, the penal effect of 3624(b)(1) is substantial enough to implicate the rule of lenity. We should not disadvantage almost 200,000 federal prisoners unless Congress clearly warned them they would face that harsh result.
The Governmentalthough not the Courtargues that we should embrace its interpretation out of deference to BOP. BOP has been charged by the Attorney General with responsibility for [a]pproving inmate disciplinary and good time regulations. 28 CFR 0.96(s) (2009). BOP has long followed the same credit-calculation method now advocated by the Court. The Government argues that we should defer to BOPs choice as a permissible exercise of its delegated responsibility.
This argument fails on multiple levels. There is no indication that BOP has exercised the sort of interpretive authority that would merit deference under Chevron U.S.A. Inc. v. Natural Resources Defense Council, Inc. , 467 U.S. 837 (1984) . The statute does not create a legislative gap for BOP to fill. To the contrary, the procedures that govern the timing of credit awards are spelled out in great detail. Cf. Lopez v. Davis , 531 U.S. 230, 241242 (2001) (where statute says that BOP may grant early release to certain prisoners, without specifying further criteria, Congress deliberately created a statutory gap). The statute even goes so far as to explain what to do [i]f the date for a prisoners release falls on a Saturday, a Sunday, or a legal holiday. 3624(a). This legislative specificity as to timing contrasts with other provisions that do delegate authority to BOP. E.g., 3624(b)(1) (awarding of credit is subject to determination by BOP that the prisoner has displayed exemplary compliance with institutional disciplinary regulations).
BOP has not claimed that its view is the product of any formal administrative procedure tending to foster the fairness and deliberation that should underlie a pronouncement with the force of law. United States v. Mead Corp. , 533 U.S. 218, 230 (2001) . In 2005, BOP made final an administrative rule adopting its preferred methodology. 70 Fed. Reg. 66752 (adopting 28 CFR 523.20). But when pressed during an earlier stage of this litigation, BOP conceded that it had failed to articulate in the administrative record the rationale upon which it relied when it promulgated the rule. Tablada v. Thomas , 533 F.3d 800, 805 (CA9 2008). The Court of Appeals accepted BOPs concession, ibid. , and that aspect of its ruling has not been appealed.
As a fallback position, the Government argues that BOPs interpretation should receive at least some deference under Skidmore v. Swift & Co. , 323 U.S. 134 (1944) . But under Skidmore , an agency decision only merits respect proportional to its power to persuade. Mead , supra , at 235 (quoting Skidmore , supra , at 140). BOPs position is of long standing, but the administrative record is noteworthy for what it does not containnamely, any reasoned justification for preferring BOPs methodology over statutorily permissible alternatives. BOP has consistently adhered to its mistaken belief that its approach is the only one that can be squared with the text. See 62 Fed. Reg. 50786 (1997) (explanation to interim rule asserting that the correct methodology had been clearly stated by statute since the implementation of the Sentencing Reform Act of 1984). For example, at no point did BOP consider, much less consciously reject, the interpretation outlined here. Cf. Reno v. Koray , 515 U.S. 50, 6061 (1995) (deferring to BOPs reasoned decision to reject one interpretation in favor of another). An agency need not consider all possible alternatives. But deference is not owed to an agency view, however consistently held, that from the start has been premised on legal error. See Mead , supra , at 228; Skidmore , supra , at 140.
The straightforward interpretation urged here accords with the purpose of the statute, which is to give prisoners incentive for good behavior and dignity from its promised reward. Prisoners can add 54 days to each year. And when they do so, they have something tangible. In place of that simple calculation, of clear meaning, of a calendar that can be marked, the Court insists on something different. It advocates an interpretation that uses different definitions for the same phrase in the same sentence; denies prisoners the benefit of the rule of lenity; and caps off its decision with an appendix that contains an algebraic formula to hang on a cell wall.
To a prisoner, time behind bars is not some theoretical or mathematical concept. It is something real, even terrifying. Survival itself may be at stake. See Dept. ofJustice, Bureau of Justice Statistics, C. Mumola, Suicide and Homicide in State Prisons and Local Jails(NCJ 210036, Aug. 2005), online at http:// bjs.ojp.usdoj.gov/content/pub/pdf/shsplj.pdf (all Internet materials as visited June 2, 2010, and available in Clerk of Courts case file) (prison homicide rates); National Prison Rape Elimination Commission Re- port,p.4(June 2009) (citing a national survey estimating that 60,500 state and federal prisoners had been sexually abused during the preceding year). To this time, the Court adds dayscompounded to years. We should not embrace this harsh result where Congress itself has not done so in clear terms. I would reverse the judgment of the Court of Appeals.
