Mr. Justice Stewart
delivered the opinion of the Court.
When at the behest of the defendant a criminal conviction has been set aside and a new trial ordered, to what extent does the Constitution limit the imposition of a harsher sentence after conviction upon retrial? That is the question presented by these two cases.
In No. 413 the respondent Pearce was convicted in a North Carolina court upon a charge of assault with intent to commit rape. The trial judge sentenced him to prison for a term of 12 to 15 years. Several years later he initiated a state post-conviction proceeding which culminated in the reversal of his conviction by the Supreme Court of North Carolina, upon the ground that an involuntary confession had unconstitutionally been admitted in evidence against him, 266 N. C. 234, 145 S. E. 2d 918. He was retried, convicted, and sentenced by the trial judge to an eight-year prison term, which, when added to the time Pearce had already spent in prison, the parties agree amounted to a longer total sentence than that originally imposed. The conviction and sentence were affirmed on appeal. 268 N. C. 707, 151 S. E. 2d 571. Pearce then began this habeas corpus proceeding in the United States District Court for the Eastern District of North Carolina. That court held, upon the authority of a then very recent Fourth Circuit decision, Patton v. North Carolina, 381 F. 2d 636, cert. denied, 390 U. S. 905, that the longer sentence imposed upon retrial was “unconstitutional and void.” Upon the failure of the state court to resentence Pearce within 60 days, the federal court ordered his release. This order was affirmed by the United States Court of Appeals for the Fourth Circuit, 397 F. 2d 253, in a brief per curiam judgment citing its Patton decision, and we granted certiorari. 393 U. S. 922.
In No. 418 the respondent Rice pleaded guilty in an Alabama trial court to four separate charges of second-degree burglary. He was sentenced to prison terms aggregating 10 years. Two and one-half years later the judgments were set aside in a state coram nobis proceeding, upon the ground that Rice had not been accorded his constitutional right to counsel. See Gideon v. Wainwright, 372 U. S. 335. He was retried upon three of the charges, convicted, and sentenced to prison terms aggregating 25 years. No credit was given for the time he had spent in prison on the original judgments. He then brought this habeas corpus proceeding in the United States District Court for the Middle District of Alabama, alleging that the state trial court had acted unconstitutionally in failing to give him credit for the time he had already served in prison, and in imposing grossly harsher sentences upon retrial. United States District Judge Frank M. Johnson, Jr., agreed with both contentions. While stating that he did “not believe that it is constitutionally impermissible to impose a harsher sentence upon retrial if there is recorded in the court record some legal justification for it,” Judge Johnson found that Rice had been denied due process of law, because “[ujnder the evidence in this case, the conclusion is inescapable that the State of Alabama is punishing petitioner Rice for his having exercised his post-conviction right of review and for having the original sentences declared unconstitutional.” 274 F. Supp. 116, 121, 122. The judgment of the District Court was affirmed by the United States Court of Appeals for the Fifth Circuit, “on the basis of Judge Johnson’s opinion,” 396 F. 2d 499, 500, and we granted certiorari. 393 U. S. 932.
The problem before us involves two related but analytically separate issues. One concerns the constitutional limitations upon the imposition of a more severe punishment after conviction for the same offense upon retrial. The other is the more limited question whether, in computing the new sentence, the Constitution requires that credit must be given for that part of the original sentence already served. The second question is not presented in Pearce, for in North Carolina it appears to be the law that a defendant must be given full credit for all time served under the previous sentence. State v. Stafford, 274 N. C. 519, 164 S. E. 2d 371; State v. Paige, 272 N. C. 417, 158 S. E. 2d 522; State v. Weaver, 264 N. C. 681, 142 S. E. 2d 633. In any event, Pearce was given such credit. Alabama law, however, seems to reflect a different view. Aaron v. State, 43 Ala. App. 450, 192 So. 2d 456; Ex parte Merkes, 43 Ala. App. 640, 198 So. 2d 789. And respondent Rice, upon being re-sentenced, was given no credit at all for the two and one-half years he had already spent in prison.
We turn first to the more limited aspect of the question before us — whether the Constitution requires that, in computing the sentence imposed after conviction upon retrial, credit must be given for time served under the original sentence. We then consider the broader question of what constitutional limitations there may be upon the imposition of a more severe sentence after reconviction.
I.
The Court has held today, in Benton v. Maryland, post, p. 784, that the Fifth Amendment guarantee against double jeopardy is enforceable against the States through the Fourteenth Amendment. That guarantee has been said to consist of three separate constitutional protections. It protects against a second prosecution for the same offense after acquittal. It protects against a second prosecution for the same offense after conviction. And it protects against multiple punishments for the same offense. This last protection is what is necessarily implicated in any consideration of the question whether, in the imposition of sentence for the same offense after retrial, the Constitution requires that credit must be given for punishment already endured. The Court stated the controlling constitutional principle almost 100 years ago, in the landmark case of Ex parte Lange, 18 Wall. 163, 168:
“If there is anything settled in the jurisprudence of England and America, it is that no man can be twice lawfully punished for the same offence. And . . . there has never been any doubt of [this rule’s] entire and complete protection of the party when a second punishment is proposed in the same court, on the same facts, for the same statutory-offence.
. . [T]he Constitution was designed as much to prevent the criminal from being twice punished for the same offence as from being twice tried for it.” Id., at 173.
We think it is clear that this basic constitutional guarantee is violated when punishment already exacted for an offense is not fully “credited” in imposing sentence upon a new conviction for the same offense. The constitutional violation is flagrantly apparent in a case involving the imposition of a maximum sentence after reconviction. Suppose, for example, in a jurisdiction where the maximum allowable sentence for larceny is 10 years’ imprisonment, a man succeeds in getting his larceny conviction set aside after serving three years in prison. If, upon reconvietion, he is given a 10-year sentence, then, quite clearly, he will have received multiple punishments for the same offense. For he will have been compelled to serve separate prison terms of three years and 10 years, although the maximum single punishment for the offense is 10 years’ imprisonment. Though not so dramatically evident, the same principle obviously holds true whenever punishment already endured is not fully subtracted from any new sentence imposed.
We hold that the constitutional guarantee against multiple punishments for the same offense absolutely requires that punishment already exacted must be fully “credited” in imposing sentence upon a new conviction for the same offense. If, upon a new trial, the defendant is acquitted, there is no way the years he spent in prison can be returned to him. But if he is reconvicted, those years can and must be returned — by subtracting them from whatever new sentence is imposed.
II.
To hold that the second sentence must be reduced by the time served under the first is, however, to give but a partial answer to the question before us. We turn, therefore, to consideration of the broader problem of what constitutional limitations there may be upon the general power of a judge to impose upon reconviction a longer prison sentence than the defendant originally received.
A.
Long-established constitutional doctrine makes clear that, beyond the requirement already discussed, the guarantee against double jeopardy imposes no restrictions upon the length of a sentence imposed upon recon-viction. At least since 1896, when United States v. Ball, 163 U. S. 662, was decided, it has been settled that this constitutional guarantee imposes no limitations whatever upon the power to retry a defendant who has succeeded in getting his first conviction set aside. “The principle that this provision does not preclude the Government’s retrying a defendant whose conviction is set aside because of an error in the proceedings leading to conviction is a well-established part of our constitutional jurisprudence.” United States v. Tateo, 377 U. S. 463, 465. And at least since 1919, when Stroud v. United States, 251 U. S. 15, was decided, it has been settled that a corollary of the power to retry a defendant is the power, upon the defendant’s reconviction, to impose whatever sentence may be legally authorized, whether or not it is greater than the sentence imposed after the first conviction. “That a defendant’s conviction is overturned on collateral rather than direct attack is irrelevant for these purposes, see Robinson v. United States, 144 F. 2d 392, 396, 397, aff’d on another ground, 324 U. S. 282.” United States v. Tateo, supra, at 466.
Although the rationale for this “well-established part of our constitutional jurisprudence” has been variously verbalized, it rests ultimately upon the premise that the original conviction has, at the defendant’s behest, been wholly nullified and the slate wiped clean. As to whatever punishment has actually been suffered under the first conviction, that premise is, of course, an unmitigated fiction, as we have recognized in Part I of this opinion. But, so far as the conviction itself goes, and that part of the sentence that has not yet been served, it is no more than a simple statement of fact to say that the slate has been wiped clean. The conviction has been set aside, and the unexpired portion of the original sentence will never be served. A new trial may result in an acquittal. But if it does result in a conviction, we cannot say that the constitutional guarantee against double jeopardy of its own weight restricts the imposition of an otherwise lawful single punishment for the offense in question. To hold to the contrary would be to cast doubt upon the whole validity of the basic principle enunciated in United States v. Ball, supra, and upon the unbroken line of decisions that have followed that principle for almost 75 years. We think those decisions are entirely sound, and we decline to depart from the concept they reflect.
B.
The other argument advanced in support of the proposition that the Constitution absolutely forbids the imposition of a more severe sentence upon retrial is grounded upon the Equal Protection Clause of the Fourteenth Amendment. The theory advanced is that, since convicts who do not seek new trials cannot have their sentences increased, it creates an invidious classification to impose that risk only upon those who succeed in getting their original convictions set aside. The argument, while not lacking in ingenuity, cannot withstand close examination. In the first place, we deal here, not with increases in existing sentences, but with the imposition of wholly new sentences after wholly new trials. Putting that conceptual nicety to one side, however, the problem before us simply cannot be rationally dealt with in terms of “classifications.” A man who is retried after his first conviction has been set aside may be acquitted. If convicted, he may receive a shorter sentence, he may receive the same sentence, or he may receive a longer sentence than the one originally imposed. The result may depend upon a particular combination of infinite variables peculiar to each individual trial. It simply cannot be said that a State has invidiously “classified” those who successfully seek new trials, any more than that the State has invidiously “classified” those prisoners whose convictions are not set aside by denying the members of that group the opportunity to be acquitted. To fit the problem of this case into an equal protection framework is a task too Procrustean to be rationally accomplished.
C.
We hold, therefore, that neither the double jeopardy provision nor the Equal Protection Clause imposes an absolute bar to a more severe sentence upon recon-viction. A trial judge is not constitutionally precluded, in other words, from imposing a new sentence, whether greater or less than the original sentence, in the light of events subsequent to the first trial that may have thrown new light upon the defendant’s “life, health, habits, conduct, and mental and moral propensities.” Williams v. New York, 337 U. S. 241, 245. Such information may come to the judge’s attention from evidence adduced at the second trial itself, from a new presentence investigation, from the defendant’s prison record, or possibly from other sources. The freedom of a sentencing judge to consider the defendant’s conduct subsequent to the first conviction in imposing a new sentence is no more than consonant with the principle, fully approved in Williams v. New York, supra, that a State may adopt the “prevalent modern philosophy of penology that the punishment should fit the offender and not merely the crime.” Id., at 247.
To say that there exists no absolute constitutional bar to the imposition of a more severe sentence upon retrial is not, however, to end the inquiry. There remains for consideration the impact of the Due Process Clause of the Fourteenth Amendment.
It can hardly be doubted that it would be a flagrant violation of the Fourteenth Amendment for a state trial court to follow an announced practice of imposing a heavier sentence upon every reconvicted defendant for the explicit purpose of punishing the defendant for his having succeeded in getting his original conviction set aside. Where, as in each of the cases before us, the original conviction has been set aside because of a constitutional error, the imposition of such a punishment, “penalizing those who choose to exercise” constitutional rights, “would be patently unconstitutional.” United States v. Jackson, 390 U. S. 570, 581. And the very threat inherent in the existence of such a punitive policy would, with respect to those still in prison, serve to “chill the exercise of basic constitutional rights.” Id., at 582. See also Griffin v. California, 380 U. S. 609; cf. Johnson v. Avery, 393 U. S. 483. But even if the first conviction has been set aside for nonconstitutional error, the imposition of a penalty upon the defendant for having successfully pursued a statutory right of appeal or collateral remedy would be no less a violation of due process of law. “A new sentence, with enhanced punishment, based upon such a reason, would be a flagrant violation of the rights of the defendant.” Nichols v. United States, 106 F. 672, 679. A court is “without right to . . . put a price on an appeal. A defendant’s exercise of a right of appeal must be free and unfettered. . . . [I]t is unfair to use the great power given to the court to determine sentence to place a defendant in the dilemma of making an unfree choice.” Worcester v. Commissioner, 370 F. 2d 713, 718. See Short v. United States, 120 U. S. App. D. C. 165, 167, 344 F. 2d 550, 552. “This Court has never held that the States are required to establish avenues of appellate review, but it is now fundamental that, once established, these avenues must be kept free of unreasoned distinctions that can only impede open and equal access to the courts. Griffin v. Illinois, 351 U. S. 12; Douglas v. California, 372 U. S. 353; Lane v. Brown, 372 U. S. 477; Draper v. Washington, 372 U. S. 487.” Rinaldi v. Yeager, 384 U. S. 305, 310-311.
Due process of law, then, requires that vindictiveness against a defendant for having successfully attacked his first conviction must play no part in the sentence he receives after a new trial. And since the fear of such vindictiveness may unconstitutionally deter a defendant's exercise of the right to appeal or collaterally attack his first conviction, due process also requires that a defendant be freed of apprehension of such a retaliatory motivation on the part of the sentencing judge.
In order to assure the absence of such a motivation, we have concluded that whenever a judge imposes a more severe sentence upon a defendant after a new trial, the reasons for his doing so must affirmatively appear. Those reasons must be based upon objective information concerning identifiable conduct on the part of the defendant occurring after the time of the original sentencing proceeding. And the factual data upon which the increased sentence is based must be made part of the record, so that the constitutional legitimacy of the increased sentence may be fully reviewed on appeal.
We dispose of the two cases before us in the light of these conclusions. In No. 418 Judge Johnson noted that “the State of Alabama offers no evidence attempting to justify the increase in Rice’s original sentences . . . .” 274 F. Supp., at 121. He found it “shocking that the State of Alabama has not attempted to explain or justify the increase in Rice’s punishment — in these three cases, over threefold.” Id., at 121-122. And he found that “the conclusion is inescapable that the State of Alabama is punishing petitioner Rice for his having exercised his post-conviction right of review . . . .” Id., at 122. In No. 413 the situation is not so dramatically clear. Nonetheless, the fact remains that neither at the time the increased sentence was imposed upon Pearce, nor at any stage in this habeas corpus proceeding, has the State offered any reason or justification for that sentence beyond the naked power to impose it. We conclude that in each of the cases before us, the judgment should be affirmed.
It is so ordered.
The approximate expiration date of the original sentence, assuming all allowances of time for good behavior, was November 13,1969. The approximate expiration date of the new sentence, assuming all allowances of time for good behavior, was October 10, 1972.
In Patton, the Court of Appeals for the Fourth Circuit had held that “increasing Patton’s punishment after the reversal of his initial conviction constitutes a violation of his Fourteenth Amendment rights in that it exacted an unconstitutional condition to the exercise of his right to a fair trial, arbitrarily denied him the equal protection of the law, and placed him twice in jeopardy of punishment for the same offense.” 381 F. 2d, at 646.
He was sentenced to four years in prison upon the first count, and two years upon each of the other three counts, the sentences to be served consecutively.
He was sentenced to a prison term of 10 years on the first count, 10 years on the second count, and five years on the fourth count, the sentences to be served consecutively. The third count was dropped upon motion of the prosecution, apparently because the chief witness for the prosecution had left the State.
The United States Courts of Appeals have reached conflicting results in dealing with the basic problem here presented. In addition to the Fourth and Fifth Circuit decisions here under review, see Marano v. United States, 374 F. 2d 583 (C. A. 1st Cir.); United States v. Coke, 404 F. 2d 836 (C. A. 2d Cir.); Starner v. Russell, 378 F. 2d 808 (C. A. 3d Cir.); United States v. White, 382 F. 2d 445 (C. A. 7th Cir.); Walsh v. United States, 374 F. 2d 421 (C. A. 9th Cir.); Newman v. Rodriguez, 375 F. 2d 712 (C. A. 10th Cir.). The state courts have also been far from unanimous. Although most of the States seem either not to have considered the problem, or to have imposed only the generally applicable statutory' limits upon sentences after retrial, a few States have prohibited more severe sentences upon retrial than were imposed at the original trial. See People v. Henderson, 60 Cal. 2d 482, 386 P. 2d 677; People v. Ali, 66 Cal. 2d 277, 424 P. 2d 932; State v. Turner, 247 Ore. 301, 429 P. 2d 565; State v. Wolf, 46 N. J. 301, 216 A. 2d 586; State v. Leonard, 39 Wis. 2d 461, 159 N. W. 2d 577.
“THE COURT: It is the intention of this Court to give the defendant a sentence of fifteen years in the State Prison; however, it appears to the Court from the records available from the Prison Department that the defendant has served 6 years, 6 months and 17 days flat and gain time combined, and the Court in passing sentence in this case is taking into consideration the time already served by the defendant. IT IS THE JUDGMENT of this Court that the defendant be confined to the State’s Prison for a period of eight years.”
A recent opinion of the Supreme Court of Alabama indicates that state law does require credit for time served under the original sentence at least to the extent that the total period of imprisonment would otherwise exceed the absolute statutory maximum that could be imposed for the offense in question. “Without such credit defendant would be serving time beyond the maximum fixed by law for the offense . . . charged in the indictment.” Goolsby v. State, 283 Ala. 269, 215 So. 2d 602.
See Note, Twice in Jeopardy, 75 Yale L. J. 262, 265-266 (1965).
United States v. Ball, 163 U. S. 662; Green v. United States, 355 U. S. 184.
In re Nielsen, 131 U. S. 176.
Ex parte Lange, 18 Wall. 163; United States v. Benz, 282 U. S. 304, 307; United States v. Sacco, 367 F. 2d 368; United States v. Adams, 362 F. 2d 210; Kennedy v. United States, 330 F. 2d 26.
We have spoken in terms of imprisonment, but the same rule would be equally applicable where a fine had been actually paid upon the first conviction. Any new fine imposed upon reconviction would have to be decreased by the amount previously paid.
Such credit must, of course, include the time credited during service of the first prison sentence for good behavior, etc.
In most situations, even when time served under the original sentence is fully taken into account, a judge can still sentence a defendant to a longer term in prison than was originally imposed. That is true with respect to both cases before us. In the Pearce case, credit for time previously served was given. See n. 6, supra. In the Rice case credit for the two and one-half years served was not given, but even if it had been, the sentencing judge could have reached the same result that he did reach simply by sentencing Rice to 27% years in prison. That would have been permissible under Alabama law, since Rice was convicted of three counts of second-degree burglary, and on each count a maximum sentence of 10 years’ imprisonment could have been imposed. Ala. Code, Tit. 14, § 86 (1958).
See, e. g., Stroud v. United States, 251 U. S. 15; Bryan v. United States, 338 U. S. 552; Forman v. United States, 361 U. S. 416; United States v. Tateo, 377 U. S. 463.
In Stroud the defendant was convicted of. first-degree murder and sentenced to life imprisonment. After reversal of this conviction, the defendant was retried, reconvicted of the same offense, and sentenced to death. This Court upheld the conviction against the defendant’s claim that his constitutional right not to be twice put in jeopardy had been violated. See also Murphy v. Massachusetts, 177 U. S. 155; Robinson v. United States, 324 U. S. 282, affirming 144 F. 2d 392. The Court’s decision in Green v. United States, 355 U. S. 184, is of no applicability to the present problem. The Green decision was based upon the double jeopardy provision’s guarantee against retrial for an offense of which the defendant was acquitted.
Cf. King v. United States, 69 App. D. C. 10, 12-13, 98 F. 2d 291, 293-294: “The Government’s brief suggests, in the vein of The Mikado, that because the first sentence was void appellant 'has served no sentence but has merely spent time in the penitentiary;’ that since he should not have been imprisoned as he was, he was not imprisoned at all.”
“While different theories have been advanced to support the permissibility of retrial, of greater importance than the conceptual abstractions employed to explain the Ball principle are the implications of that principle for the sound administration of justice. Corresponding to the right of an accused to be given a fair trial is the societal interest in punishing one whose guilt is clear after he has obtained such a trial. It would be a high price indeed for society to pay were every accused granted immunity from punishment because of any defect sufficient to constitute reversible error in the proceedings leading to conviction. From the standpoint of a defendant, it is at least doubtful that appellate courts would be as zealous as they now are in protecting against the effects of improprieties at the trial or pretrial stage if they knew that reversal of a conviction would put the accused irrevocably beyond the reach of further prosecution. In reality, therefore, the practice of retrial serves defendants' rights as well as society’s interest.” United States v. Tateo, 377 U. S. 463, 466.
See Van Alstyne, In Gideon’s Wake: Harsher Penalties and the “Successful” Criminal Appellant, 74 Yale L. J. 606 (1965); Note, Unconstitutional Conditions, 73 Harv. L. Rev. 1595 (1960).
The existence of a retaliatory motivation would, of course, be extremely difficult to prove in any individual case. But data have been collected to show that increased sentences on reconviction are far from rare. See Note, Constitutional Law: Increased Sentence and Denial of Credit on Retrial Sustained Under Traditional Waiver Theory, 1965 Duke L. J. 395. A touching bit of evidence showing the fear of such a vindictive policy was noted by the trial judge in Patton v. North Carolina, 256 F. Supp. 225, who quoted a letter he had recently received from a prisoner:
“Dear Sir:
“I am in the Mecklenburg County jail. Mr. - chose to re-try me as I knew he would.
“Sir the other defendant in this case was set free after serving 15 months of his sentence, I have served 34 months and now I am to be tried again and with all probility I will receive a heavier sentence then before as you know sir my sentence at the first trile was 20 to 30 years. I know it is usuelly the courts prosedure to give a larger sentence when a new trile is granted I guess this is to discourage Petitioners.
“Your Honor, I don’t want a new trile I am afraid of more time ....
“Your Honor, I know you have tried to help me and God knows I apreeeate this but please sir don’t let the state re-try me if there is any way you can prevent it.”
“Very truly yours”

What follows is an opinion from the Supreme Court of the United States. Your task is to determine whether the decision of the court whose decision the Supreme Court reviewed was itself liberal or conservative. In the context of issues pertaining to criminal procedure, civil rights, First Amendment, due process, privacy, and attorneys, consider liberal to be pro-person accused or convicted of crime, or denied a jury trial, pro-civil liberties or civil rights claimant, especially those exercising less protected civil rights (e.g., homosexuality), pro-child or juvenile, pro-indigent pro-Indian, pro-affirmative action, pro-neutrality in establishment clause cases, pro-female in abortion, pro-underdog, anti-slavery, incorporation of foreign territories anti-government in the context of due process, except for takings clause cases where a pro-government, anti-owner vote is considered liberal except in criminal forfeiture cases or those where the taking is pro-business violation of due process by exercising jurisdiction over nonresident, pro-attorney or governmental official in non-liability cases, pro-accountability and/or anti-corruption in campaign spending pro-privacy vis-a-vis the 1st Amendment where the privacy invaded is that of mental incompetents, pro-disclosure in Freedom of Information Act issues except for employment and student records. In the context of issues pertaining to unions and economic activity, consider liberal to be pro-union except in union antitrust where liberal = pro-competition, pro-government, anti-business anti-employer, pro-competition, pro-injured person, pro-indigent, pro-small business vis-a-vis large business pro-state/anti-business in state tax cases, pro-debtor, pro-bankrupt, pro-Indian, pro-environmental protection, pro-economic underdog pro-consumer, pro-accountability in governmental corruption, pro-original grantee, purchaser, or occupant in state and territorial land claims anti-union member or employee vis-a-vis union, anti-union in union antitrust, anti-union in union or closed shop, pro-trial in arbitration. In the context of issues pertaining to judicial power, consider liberal to be pro-exercise of judicial power, pro-judicial "activism", pro-judicial review of administrative action. In the context of issues pertaining to federalism, consider liberal to be pro-federal power, pro-executive power in executive/congressional disputes, anti-state. In the context of issues pertaining to federal taxation, consider liberal to be pro-United States and conservative pro-taxpayer. In miscellaneous, consider conservative the incorporation of foreign territories and executive authority vis-a-vis congress or the states or judcial authority vis-a-vis state or federal legislative authority, and consider liberal legislative veto. The lower court's decision direction is unspecifiable if the manner in which the Supreme Court took jurisdiction is original or certification; or if the direction of the Supreme Court's decision is unspecifiable and the main issue pertains to private law or interstate relations
