Skipper v. South Carolina
Argued February 24, 1986
Decided April 29, 1986
476 U.S. 1
CERTIORARI TO THE SUPREME COURT OF SOUTH CAROLINA
Petitioner was convicted of capital murder and rape after a jury trial in a South Carolina court. The State sought the death penalty, and a separate sentencing hearing was held before the trial jury. Following the State's introduction of evidence in aggravation of the offense, petitioner presented as mitigating evidence his own testimony and that of his former wife, his mother, his sister, and his grandmother. He then sought to introduce testimony of two jailers and a "regular visitor" to the effect that he had "made a good adjustment" during the 7 1/2 months he had spent in jail between his arrest and trial. The trial court ruled such evidence irrelevant and inadmissible, and petitioner was sentenced to death. The South Carolina Supreme Court affirmed the death sentence, rejecting petitioner's contention that the trial court had committed constitutional error in excluding the testimony of the jailers and visitor.
Held: The trial court's exclusion from the sentencing hearing of the testimony of the jailers and the visitor denied petitioner his right to place before the sentencing jury all relevant evidence in mitigation of punishment. Lockett v. Ohio, 438 U. S. 586; Eddings v. Oklahoma, 455 U. S. 104. Pp. 476 U. S. 4-9.
(a) The record does not support the State's contention that the trial court's ruling was no more than an application of rules restricting the use of lay opinion testimony. Pp. 476 U. S. 5-6.
(b) Nor is there any support in the record for the State's contention that the trial court's ruling was not improper because it did not prevent petitioner from introducing evidence of past good conduct in jail, but chanroblesvirtualawlibrary
only foreclosed the introduction of "irrelevant" evidence of his future adaptability to prison life. Pp. 476 U. S. 6-7.
(c) And, contrary to the State's suggestion, it is implausible, on the facts, to characterize the excluded evidence as cumulative, and its exclusion as harmless error. Pp. 476 U. S. 7-9.
285 S.C. 42, 328 S.E.2d 68, reversed and remanded.

JUSTICE WHITE delivered the opinion of the Court.
Petitioner Ronald Skipper was convicted in a South Carolina trial court of capital murder and rape. The State sought the death penalty, and a separate sentencing hearing was held before the trial jury under S.C.Code § 16-3-20 (1985), which provides for a bifurcated trial and jury sentencing in capital cases. Following introduction by the State of evidence in aggravation of the offense (principally evidence of petitioner's history of sexually assaultive behavior), petitioner presented as mitigating evidence his own testimony and that of his former wife, his mother, his sister, and his grandmother. This testimony, for the most part, concerned chanroblesvirtualawlibrary
the difficult circumstances of his upbringing. Petitioner and his former wife, however, both testified briefly that petitioner had conducted himself well during the 7 1/2 months he spent in jail between his arrest and trial. Petitioner also testified that, during a prior period of incarceration, he had earned the equivalent of a high school diploma, and that, if sentenced to life imprisonment rather than to death, he would behave himself in prison, and would attempt to work so that he could contribute money to the support of his family.
Petitioner also sought to introduce testimony of two jailers and one "regular visitor" to the jail to the effect that petitioner had "made a good adjustment" during his time spent in jail. The trial court, however, ruled that, under the South Carolina Supreme Court's decision in State v. Koon, 278 S.C. 528, 298 S.E.2d 769 (1982) (Koon I), such evidence would be irrelevant, and hence inadmissible. The decision in Koon I, the judge stated, stood for the rule that "whether [petitioner] can adjust or not adjust" was "not an issue in this case." App. 11.
After hearing closing arguments -- during the course of which the prosecutor contended that petitioner would pose disciplinary problems if sentenced to prison, and would likely rape other prisoners, id. at 13-14 -- the jury sentenced petitioner to death. On appeal, petitioner contended that the trial court had committed constitutional error in excluding the testimony of the jailers and the visitor: the testimony of these witnesses, petitioner argued, would have constituted relevant mitigating evidence, and exclusion of such evidence was improper under this Court's decisions in Lockett v. Ohio, 438 U. S. 586 (1978), and Eddings v. Oklahoma, 455 U. S. 104 (1982). The Supreme Court of South Carolina rejected petitioner's contention, stating:
"The trial judge properly refused to admit evidence of [petitioner's] future adaptability to prison life. State v. Koon, supra. However, evidence of his past adaptability was admitted through testimony of his former wife,
his mother, and his own testimony. This contention is without merit."
285 S.C. 42, 48, 328 S.E.2d 58, 61-62 (1985). We granted certiorari, 474 U.S. 900 (1985), to consider petitioner's claim that the South Carolina Supreme Court's decision is inconsistent with this Court's decisions in Lockett and Eddings, and we now reverse.
There is no disputing that this Court's decision in Eddings requires that, in capital cases,
"'the sentencer . . . not be precluded from considering, as a mitigating factor, any aspect of a defendant's character or record and any of the circumstances of the offense that the defendant proffers as a basis for a sentence less than death.'"
Eddings, supra, at 455 U. S. 110 (quoting Lockett, supra, at 438 U. S. 604 (plurality opinion of BURGER, C.J.)) (emphasis in original). Equally clear is the corollary rule that the sentencer may not refuse to consider or be precluded from considering "any relevant mitigating evidence." 455 U.S. at 455 U. S. 114. These rules are now well established, and the State does not question them.
Accordingly, the only question before us is whether the exclusion from the sentencing hearing of the testimony petitioner proffered regarding his good behavior during the over seven months he spent in jail awaiting trial deprived petitioner of his right to place before the sentencer relevant evidence in mitigation of punishment. It can hardly be disputed that it did. The State does not contest that the witnesses petitioner attempted to place on the stand would have testified that petitioner had been a well-behaved and well-adjusted prisoner, nor does the State dispute that the jury could have drawn favorable inferences from this testimony regarding petitioner's character and his probable future conduct if sentenced to life in prison. Although it is true that any such inferences would not relate specifically to petitioner's culpability for the crime he committed, see Koon I, supra, at 536, 298 S.E.2d at 774, there is no question but that such inferences would be "mitigating" in the sense that chanroblesvirtualawlibrary
they might serve "as a basis for a sentence less than death." Lockett, supra, at 438 U. S. 604. Consideration of a defendant's past conduct as indicative of his probable future behavior is an inevitable and not undesirable element of criminal sentencing:
"any sentencing authority must predict a convicted person's probable future conduct when it engages in the process of determining what punishment to impose."
Jurek v. Texas, 428 U. S. 262, 275 (1976) (opinion of Stewart, POWELL, and STEVENS, JJ.). The Court has therefore held that evidence that a defendant would in the future pose a danger to the community if he were not executed may be treated as establishing an "aggravating factor" for purposes of capital sentencing, Jurek v. Texas, supra; see also Barefoot v. Estelle, 463 U. S. 880 (1983). Likewise, evidence that the defendant would not pose a danger if spared (but incarcerated) must be considered potentially mitigating. [Footnote 1] Under Eddings, such evidence may not be excluded from the sentencer's consideration.
The State advances several arguments as to why the exclusion of petitioner's proffered evidence was, nonetheless, not erroneous. First, the State contends that the trial court ruled only that petitioner's witnesses could not offer incompetent lay opinion testimony regarding petitioner's ability to adjust to prison life in the future. Eddings, the State argues, does not displace reasonable state law rules regarding the competency of testimony. The record does not, however, support the State's contention that the trial court's chanroblesvirtualawlibrary
ruling was no more than an evenhanded application of rules restricting the use of opinion testimony. It is true that petitioner's request for a ruling on the admissibility of the testimony of the two jailers and the "regular visitor" was immediately preceded by an attempt to introduce his former wife's opinion (ruled inadmissible by the trial judge, App. 10) regarding his prospects for adjustment to prison life. In seeking a ruling on the testimony of the three witnesses at issue here, however, petitioner made it clear that he expected them "to testify that [petitioner] has made a good adjustment" to jail. Id. at 11 (emphasis added). Defense counsel was not offering opinion testimony regarding future events. Under these circumstances, any ruling premised on the assumption that petitioner planned to present incompetent opinion testimony would have been -- as the State conceded at oral argument -- a "mistake." Such a misunderstanding could by no means justify the exclusion of nonopinion evidence bearing on the defendant's ability to adjust to prison life.
Second, the State echoes the South Carolina Supreme Court in arguing that the trial court's ruling was not improper, because it did not prevent petitioner from introducing evidence of past good conduct in jail for purposes of establishing his good character, but only foreclosed the introduction of "irrelevant" evidence of his future adaptability to prison life. There is no clear support for this contention in the record of this case, as the trial court did not explicitly rely on any such distinction, and appears to have excluded petitioner's evidence of good conduct for any purpose whatsoever. The State's proposed distinction between use of evidence of past good conduct to prove good character and use of the same evidence to establish future good conduct in prison seems to be drawn from the decision of the South Carolina Supreme Court in another case altogether, State v. Koon, 285 S.C. 1, 328 S.E.2d 625 (Koon II), cert. denied, 471 U. S. 1036 (1985). There, the court stated that although
adaptability to prison [is] irrelevant evidence because it does not bear on a defendant's character, prior record, or the circumstances of his offense[,] . . . [p]ast behavior in prison does bear on a defendant's character and, therefore, is relevant."
285 S.C. at 3, 328 S.E.2d at 626. This distinction is elusive. As we have explained above, a defendant's disposition to make a well-behaved and peaceful adjustment to life in prison is itself an aspect of his character that is, by its nature, relevant to the sentencing determination. [Footnote 2] Accordingly, the precise meaning and practical significance of the decision in Koon II and of the State's argument is difficult to assess. Assuming, however, that the rule would, in any case, have the effect of precluding the defendant from introducing otherwise admissible evidence for the explicit purpose of convincing the jury that he should be spared the death penalty because he would pose no undue danger to his jailers or fellow prisoners, and could lead a useful life behind bars if sentenced to life imprisonment, the rule would not pass muster under Eddings. Since the trial court's ruling in this case -- whether or not it can credibly be said to be consistent with Koon II, at least had this effect, it cannot stand under Eddings.
Finally, the State seems to suggest that exclusion of the proffered testimony was proper because the testimony was merely cumulative of the testimony of petitioner and his former chanroblesvirtualawlibrary
wife that petitioner's behavior in jail awaiting trial was satisfactory, and of petitioner's testimony that, if sentenced to prison rather than to death, he would attempt to use his time productively, and would not cause trouble. We think, however, that characterizing the excluded evidence as cumulative and its exclusion as harmless is implausible on the facts before us. The evidence petitioner was allowed to present on the issue of his conduct in jail was the sort of evidence that a jury naturally would tend to discount as self-serving. The testimony of more disinterested witnesses -- and, in particular, of jailers who would have had no particular reason to be favorably predisposed toward one of their charges -- would quite naturally be given much greater weight by the jury. Nor can we confidently conclude that credible evidence that petitioner was a good prisoner would have had no effect upon the jury's deliberations. The prosecutor himself, in closing argument, made much of the dangers petitioner would pose if sentenced to prison, and went so far as to assert that petitioner could be expected to rape other inmates. Under these circumstances, it appears reasonably likely that the exclusion of evidence bearing upon petitioner's behavior in jail (and hence, upon his likely future behavior in prison) may have affected the jury's decision to impose the death sentence. Thus, under any standard, the exclusion of the evidence was sufficiently prejudicial to constitute reversible error.
The exclusion by the state trial court of relevant mitigating evidence impeded the sentencing jury's ability to carry out its task of considering all relevant facets of the character and record of the individual offender. The resulting death sentence cannot stand, although the State is of course not precluded from again seeking to impose the death sentence, provided that it does so through a new sentencing hearing at which petitioner is permitted to present any and all relevant mitigating evidence that is available. Eddings, 455 U.S. at 455 U. S. 117. The judgment of the Supreme Court of South Carolina chanroblesvirtualawlibrary
is therefore reversed insofar as it affirms the death sentence, and the case is remanded for further proceedings not inconsistent with this opinion.
It is so ordered.
The relevance of evidence of probable future conduct in prison as a factor in aggravation or mitigation of an offense is underscored in this particular case by the prosecutor's closing argument, which urged the jury to return a sentence of death in part because petitioner could not be trusted to behave if he were simply returned to prison. Where the prosecution specifically relies on a prediction of future dangerousness in asking for the death penalty, it is not only the rule of Lockett and Eddings that requires that the defendant be afforded an opportunity to introduce evidence on this point; it is also the elemental due process requirement that a defendant not be sentenced to death "on the basis of information which he had no opportunity to deny or explain." Gardner v. Florida, 430 U. S. 349, 430 U. S. 362 (1977).
We do not hold that all facets of the defendant's ability to adjust to prison life must be treated as relevant and potentially mitigating. For example, we have no quarrel with the statement of the Supreme Court of South Carolina that "how often [the defendant] will take a shower" is irrelevant to the sentencing determination. State v. Plath, 281 S.C. 1, 15, 313 S.E.2d 619, 627, cert. denied, 467 U. S. 1265 (1984). In the case before us, there is no credible suggestion that petitioner sought to introduce evidence of his personal hygiene practices. Rather, petitioner apparently attempted to introduce evidence suggesting that he had been a well-behaved and disciplined prisoner. Such evidence of adjustability to life in prison unquestionably goes to a feature of the defendant's character that is highly relevant to a jury's sentencing determination.
JUSTICE POWELL, with whom THE CHIEF JUSTICE and JUSTICE REHNQUIST join, concurring in the judgment.
Although I agree that petitioner's death sentence must be vacated, that result is not required by our decisions in Lockett v. Ohio, 438 U. S. 586 (1978), and Eddings v. Oklahoma, 455 U. S. 104 (1982). I would reverse the judgment below, not because the trial court excluded "relevant mitigating evidence" within the meaning of those decisions, id. at 455 U. S. 114; see Lockett, supra, at 438 U. S. 604-605, but because petitioner was not allowed to rebut evidence and argument used against him. See Gardner v. Florida, 430 U. S. 349 (1977).
In the course of cross-examining petitioner at his sentencing proceeding, the prosecutor adduced testimony that petitioner had kicked the bars of his cell following his arrest. [Footnote 2/1] In closing argument, the prosecutor contended that petitioner was likely to commit violent crimes in prison if allowed to live, and referred to the incident in petitioner's cell to support his characterization of petitioner as a hopelessly violent man:
"[Petitioner's] wife said he told her . . . that he had been raped in prison. With his history and what you know about him, who do you think the raper was and who do
you think the rapee was? And if given the opportunity again with this four-time sexual abusing loser, who do you think will get raped in prison? Will it be Ronald Skipper, big old robust Ronald Skipper who knocks woman [sic] in the side of the head, or will it be some little boy in prison?"
"* * * *"
"These are the mitigating circumstances submitted by the defendant. . . . That the defendant has shown significant and positive adjustments to confinement and education and employment skills that enable him to be a stable and productive prisoner. Didn't he admit kicking on the bars over there? That's the kind of prisoner he is. Kicking on the bar. Kicking on the bars. . . ."
Petitioner had offered evidence that would undermine this line of argument: the testimony of two guards and a prison visitor, all of whom would have testified that petitioner had behaved well while in prison awaiting trial. The trial court excluded that evidence, relying on the Supreme Court of South Carolina's decision in State v. Koon, 278 S.C. 528, 298 S.E.2d 769 (1982). Petitioner was sentenced to death, and the Supreme Court of South Carolina affirmed the sentence. 285 S.C. 42, 328 S.E.2d 58 (1985).
The Court correctly concludes that the exclusion of the proffered testimony violated due process. Ante at 476 U. S. 5, n. 1. In Gardner v. Florida, supra, we vacated a death sentence on the ground that the sentencing judge had considered a confidential presentence report without permitting the defendant to see the report. The plurality concluded that the defendant was denied due process because "the death sentence was imposed, at least in part, on the basis of information which he had no opportunity to deny or explain." Id. at 430 U. S. 362 (opinion of STEVENS, J.). See also id. at 430 U. S. 364 (WHITE, J., concurring in judgment) (applying the same analysis chanroblesvirtualawlibrary
under the Eighth Amendment). As in Gardner, petitioner in this case was not permitted to "deny or explain" evidence on which his death sentence may, in part, have rested. This error was aggravated by the prosecutor's closing argument, which emphasized and exaggerated petitioner's misconduct in prison after his arrest. Therefore, petitioner's death sentence violates the rule in Gardner.
The Court unnecessarily abandons this narrow ground of decision for a broader one, holding that the proffered testimony was mitigating evidence that must be admitted under the Eighth Amendment. In my view, the Court's reasoning is flawed. The Eighth Amendment requires that the sentencing authority consider "relevant mitigating evidence" concerning the defendant's "character or record" and "the circumstances of the offense." Eddings v. Oklahoma, supra, at 455 U. S. 114; Lockett v. Ohio, supra, at 438 U. S. 604. But the States, and not this Court, retain "the traditional authority" to determine what particular evidence within the broad categories described in Lockett and Eddings is relevant in the first instance. 438 U.S. at 438 U. S. 604, n. 12. As long as those determinations are reasonable -- as long as they do not foreclose consideration of factors that may tend to reduce the defendant's culpability for his crime, see Eddings, supra, at 455 U. S. 115-116 -- this Court should respect them.
I see no reason why a State could not, consistent with these principles, exclude evidence of a defendant's good behavior in jail following his arrest, as long as the evidence is not offered to rebut testimony or argument such as that tendered by the prosecution here. Such evidence has no bearing at all on the "circumstances of the offense," since it concerns the defendant's behavior after the crime has been committed. Nor does it say anything necessarily relevant chanroblesvirtualawlibrary
about a defendant's "character or record," as that phrase was used in Lockett and Eddings.
Those decisions clearly focus on evidence that lessens the defendant's culpability for the crime for which he was convicted. The sentencing jury in Lockett was barred from considering evidence of the defendant's youth, her "lack of specific intent to cause death," and "her relatively minor part in the crime." 438 U.S. at 438 U. S. 597. Such evidence obviously bore strongly on the degree to which the defendant was morally responsible for her crime; indeed, we have since held that similar evidence precludes application of the death penalty for precisely this reason. Enmund v. Florida, 458 U. S. 782, 458 U. S. 798-801 (1982). In Eddings, the judge refused to consider the defendant's youth and history of "beatings by a harsh father, and of severe emotional disturbance." 455 U.S. at 455 U. S. 115. We emphasized that this evidence tended to diminish the defendant's responsibility for his acts, noting that youths "are less mature and responsible than adults," id. at 455 U. S. 116, and that they
"'deserve less punishment, because adolescents may have less capacity to control their conduct and to think in long-range terms than adults.'"
Id. at 455 U. S. 115, n. 11, quoting Twentieth Century Fund Task Force on Sentencing Policy Toward Young Offenders, Confronting Youth Crime 7 (1978). The type of evidence required to be admitted under Lockett and Eddings thus pertained to conduct and circumstances prior to the crime, and to the nature and extent of the defendant's participation in the crime. In this case, for the first time, the Court classifies as "mitigating" conduct that occurred after the crime, and after the accused has been charged. Almost by definition, such conduct neither excuses the defendant's crime nor reduces his responsibility for its commission. It cannot, therefore, properly be considered "mitigating evidence" that the sentencer must consider under the Constitution. chanroblesvirtualawlibrary
It is useful to recall the origins of the rule the Court applies today. Ten years ago, in Woodson v. North Carolina, 428 U. S. 280 (1976), we determined that States could not carry out the death penalty without some "particularized consideration of relevant aspects of the character and record of each convicted defendant." Id. at 428 U. S. 303 (plurality opinion). See also Roberts v. Louisiana, 428 U. S. 325, 428 U. S. 333-336 (1976) (plurality opinion). That determination flowed from the conviction that "individual culpability is not always measured by the category of the crime committed." Furman v. Georgia, 408 U. S. 238, 408 U. S. 402 (1972) (BURGER, C.J.,dissenting), quoted in Woodson, supra, at 428 U. S. 298. See also Roberts, supra, at 428 U. S. 333. Thus, we reasoned, it was unconstitutionally arbitrary to execute a man or woman without considering factors showing that death was not a "just and appropriate sentence." Woodson, supra, at 428 U. S. 304. Cf. Enmund v. Florida, supra.
Lockett and Eddings followed naturally from our decision in Woodson. But it also follows from Woodson and its companion cases that States are only bound to consider those factors that are central to the fundamental justice of execution. We have recognized that society has important and legitimate interests in retribution and deterrence, and that these interests provide the necessary justification for imposing the death penalty. Gregg v. Georgia, 428 U. S. 153, 428 U. S. 183-187 (1976) (joint opinion). Society's legitimate desire for retribution is less strong with respect to a defendant who played a minor role in the murder for which he was convicted. Cf. Lockett, 438 U.S. at 438 U. S. 597. Similarly, the death penalty has little deterrent force against defendants who have reduced capacity for considered choice. Cf. Eddings, 455 U.S. at 455 U. S. 115, n. 11. Evidence concerning the degree of the defendant's participation in the crime, or his age and emotional history, thus bear directly on the fundamental justice chanroblesvirtualawlibrary
of imposing capital punishment. That simply cannot be said of the defendant's behavior in prison following his arrest. Society's interest in retribution can hardly be lessened by the knowledge that a brutal murderer, for self-interested reasons, has been a model of deportment in prison while awaiting trial or sentence. Nor is society's important interest in deterrence served by allowing such a murderer to avoid the death penalty by following his counsel's advice to behave himself in a tightly controlled prison environment. [Footnote 2/2]
Even if a defendant's apparent capacity to adjust well to prison fell within the scope of the mitigating factors that must be considered under Lockett and Eddings, a State should have the right to exclude evidence of conduct in prison while awaiting trial or sentencing. One arrested for a capital crime, and particularly a convicted defendant awaiting sentencing, has every incentive to behave flawlessly in prison if good behavior might cause the sentencing authority to spare his life. [Footnote 2/3] Good behavior in those circumstances would chanroblesvirtualawlibrary
rarely be predictive as to the conduct of the prisoner after sentence has been imposed. For this further reason, state courts reasonably could determine that such evidence has little or no probative value. Certainly it will not aid the sentencer in "distinguishing the few cases in which [the death penalty] is imposed from the many cases in which it is not." Furman v. Georgia, supra, at 408 U. S. 313 (WHITE, J., concurring), quoted in Gregg v. Georgia, supra, at 428 U. S. 188.
The Court's contrary determination apparently rests on the notion that the States have little or no authority to decide that certain types of evidence may have insufficient probative value to justify their admission. But cf. ante at 476 U. S. 7, n. 2. Lockett explicitly rejected such an approach, 438 U.S. at 438 U. S. 604, n. 12, and for good reason. This Court has no special expertise in deciding whether particular categories of evidence are too speculative or insubstantial to merit consideration by the sentencer. Cf. Barefoot v. Estelle, 463 U. S. 880, 463 U. S. 899-902 (1983). It makes little sense, then, to substitute our judgment of relevance for that of state courts and legislatures. Nor is such intrusive review necessary in this context to guard against fundamentally unjust executions. One cannot plausibly equate the type of evidence at issue in Lockett and Eddings with evidence that a capital defendant has refrained from assaulting anyone in prison while awaiting trial or sentencing. I would therefore leave the disposition of evidence of the kind involved here to the States, subject to the requirements of due process.
The following colloquy took place at the close of the cross-examination:
"Q: You are the fellow that, when you got to the Horry County jail went to kicking the cell, right?"
"A: Yes, Sir."
"Q: That's you. [T]hat's the kind of fellow you are, but you are nice today, right?"
We have noted that, for many types of murders, "the death penalty undoubtedly is a significant deterrent." Gregg v. Georgia, 428 U. S. 153, 428 U. S. 185-186 (1976). See also id. at 428 U. S. 186 (actual deterrent value of death penalty in particular contexts "is a complex factual issue, the resolution of which properly rests with the legislatures"). This deterrent value inevitably is diluted when defendants are allowed to escape execution based on factors that have nothing to do with their criminal responsibility. The consequences of such mistakes extend further than the cases in which they occur, for when some defendants are able to avoid execution based on irrelevant criteria, there is a far graver risk of injustice in executing others. See Furman v. Georgia, 408 U. S. 238, 408 U. S. 311-314 (1972) (WHITE, J., concurring). I thus find it difficult to accept the proposition that the Constitution compels States to consider factors, such as a defendant's willingness to conform to prison rules, that plainly undermine deterrence without advancing retributive goals.
After today's decision, competent defense counsel in capital cases will instruct their clients to behave like Eagle Scouts while awaiting trial, and particularly while awaiting sentencing. In capital cases, this will be more important to a defendant than the customary advice of counsel in a criminal trial to advise his client to behave himself while in the courtroom. It is indeed novel doctrine that compliance with this advice by a defendant charged with capital murder becomes a "mitigating factor" that the sentencing judge or jury must -- as a matter of constitutional law -- consider in passing sentence.
