PATTERSON v. NEW YORK
APPEAL FROM THE COURT OF APPEALS OF NEW YORK
Argued March 1, 1977
Decided June 17, 1977
New York law requiring that the defendant in a prosecution for second-degree murder prove by a preponderance of the evidence the affirmative defense of extreme emotional disturbance in order to reduce the crime to manslaughter held not to violate the Due Process Clause of the Fourteenth Amendment. Mullaney v. Wilbur, 421 U.S. 684 , distinguished. Pp. 201-216.
WHITE, J., delivered the opinion of the Court, in which BURGER, C. J., and STEWART, BLACKMUN, and STEVENS, JJ., joined. POWELL, J., filed a dissenting opinion, in which BRENNAN and MARSHALL, JJ., joined, post, p. 216. REHNQUIST, J., took no part in the consideration or decision of the case.
Victor J. Rubino argued the cause for appellant. With him on the briefs was Betty D. Friedlander.
John M. Finnerty argued the cause for appellee. With him on the brief was Alan D. Marrus. [432 U.S. 197, 198]
MR. JUSTICE WHITE delivered the opinion of the Court.
The question here is the constitutionality under the Fourteenth Amendment's Due Process Clause of burdening the defendant in a New York State murder trial with proving the affirmative defense of extreme emotional disturbance as defined by New York law.
After a brief and unstable marriage, the appellant, Gordon Patterson, Jr., became estranged from his wife, Roberta. Roberta resumed an association with John Northrup, a neighbor to whom she had been engaged prior to her marriage to appellant. On December 27, 1970, Patterson borrowed a rifle from an acquaintance and went to the residence of his father-in-law. There, he observed his wife through a window in a state of semiundress in the presence of John Northrup. He entered the house and killed Northrup by shooting him twice in the head.
Patterson was charged with second-degree murder. In New York there are two elements of this crime: (1) "intent to cause the death of another person"; and (2) "caus[ing] the death of such person or of a third person." N. Y. Penal Law 125.25 (McKinney 1975). 1 Malice aforethought is not an element of the crime. In addition, the State permits a person accused of murder to raise an affirmative defense that he "acted under the influence of extreme emotional disturbance for which there was a reasonable explanation or excuse." 2 [432 U.S. 197, 199]
New York also recognizes the crime of manslaughter. A person is guilty of manslaughter if he intentionally kills another person "under circumstances which do not constitute murder because he acts under the influence of extreme emotional disturbance." 3 Appellant confessed before trial to killing Northrup, but at trial he raised the defense of extreme emotional disturbance. 4
The jury was instructed as to the elements of the crime of murder. Focusing on the element of intent, the trial court charged:
The jury found appellant guilty of murder. Judgment was entered on the verdict, and the Appellate Division affirmed. While appeal to the New York Court of Appeals was pending, this Court decided Mullaney v. Wilbur, 421 U.S. 684 (1975), in which the Court declared Maine's murder statute unconstitutional. Under the Maine statute, a person accused of murder could rebut the statutory presumption that he committed [432 U.S. 197, 201] the offense with "malice aforethought" by proving that he acted in the heat of passion on sudden provocation. The Court held that this scheme improperly shifted the burden of persuasion from the prosecutor to the defendant and was therefore a violation of due process. In the Court of Appeals appellant urged that New York's murder statute is functionally equivalent to the one struck down in Mullaney and that therefore his conviction should be reversed. 6
The Court of Appeals rejected appellant's argument, holding that the New York murder statute is consistent with due process. 39 N. Y. 2d 288, 347 N. E. 2d 898 (1976). The Court distinguished Mullaney on the ground that the New York statute involved no shifting of the burden to the defendant to disprove any fact essential to the offense charged since the New York affirmative defense of extreme emotional disturbance bears no direct relationship to any element of murder. This appeal ensued, and we noted probable jurisdiction. 429 U.S. 813 (1976). We affirm.
It goes without saying that preventing and dealing with crime is much more the business of the States than it is of the Federal Government, Irvine v. California, 347 U.S. 128, 134 (1954) (plurality opinion), and that we should not lightly construe the Constitution so as to intrude upon the administration of justice by the individual States. Among other things, it is normally "within the power of the State to regulate procedures under which its laws are carried out, including the burden of producing evidence and the burden of persuasion," and its decision in this regard is not subject to proscription [432 U.S. 197, 202] under the Due Process Clause unless "it offends some principle of justice so rooted in the traditions and conscience of our people as to be ranked as fundamental." Speiser v. Randall, 357 U.S. 513, 523 (1958); Leland v. Oregon, 343 U.S. 790, 798 (1952); Snyder v. Massachusetts, 291 U.S. 97, 105 (1934).
In determining whether New York's allocation to the defendant of proving the mitigating circumstances of severe emotional disturbance is consistent with due process, it is therefore relevant to note that this defense is a considerably expanded version of the common-law defense of heat of passion on sudden provocation and that at common law the burden of proving the latter, as well as other affirmative defense - indeed, "all . . . circumstances of justification, excuse or alleviation" - rested on the defendant. 4 W. Blackstone, Commentaries *201; M. Foster, Crown Law 255 (1762); Mullaney v. Wilbur, supra, at 693-694. 7 This was the rule when the Fifth Amendment was adopted, and it was the American rule when the Fourteenth Amendment was ratified. Commonwealth v. York, 50 Mass. 93 (1845). 8
In 1895 the common-law view was abandoned with respect to the insanity defense in federal prosecutions. Davis v. United States, 160 U.S. 469 (1895). This ruling had wide impact on the practice in the federal courts with respect to the burden of proving various affirmative defenses, and the prosecution [432 U.S. 197, 203] in a majority of jurisdictions in this country sooner or later came to shoulder the burden of proving the sanity of the accused and of disproving the facts constituting other affirmative defenses, including provocation. Davis was not a constitutional ruling, however, as Leland v. Oregon, supra, made clear. 9 [432 U.S. 197, 204]
At issue in Leland v. Oregon was the constitutionality under the Due Process Clause of the Oregon rule that the defense of insanity must be proved by the defendant beyond a reasonable doubt. Nothing that Davis "obviously establish[ed] no constitutional doctrine," 343 U.S., at 797 , the Court refused to strike down the Oregon scheme, saying that the burden of proving all elements of the crime beyond a reasonable doubt, including the elements of premeditation and deliberation, was placed on the State under Oregon procedures and remained there throughout the trial. To convict, the jury was required to find each element of the crime beyond a reasonable doubt, based on all the evidence, including the evidence going to the issue of insanity. Only then was the jury "to consider separately the issue of legal sanity per se . . . ." Id., at 795. This practice did not offend the Due Process Clause even though among the 20 States then placing the burden of proving his insanity on the defendant, Oregon was alone in requiring him to convince the jury beyond a reasonable doubt.
In 1970, the Court declared that the Due Process Clause "protects the accused against conviction except upon proof beyond a reasonable doubt of every fact necessary to constitute the crime with which he is charged." In re Winship, 397 U.S. 358 , [432 U.S. 197, 205] 364 (1970). Five years later, in Mullaney v. Wilbur, 421 U.S. 684 (1975), the Court further announced that under the Maine law of homicide, the burden could not constitutionally be placed on the defendant of proving by a preponderance of the evidence that the killing had occurred in the heat of passion on sudden provocation. THE CHIEF JUSTICE and MR. JUSTICE REHNQUIST, concurring, expressed their understanding that the Mullaney decision did not call into question the ruling in Leland v. Oregon, supra, with respect to the proof of insanity.
Subsequently, the Court confirmed that it remained constitutional to burden the defendant with proving his insanity defense when it dismissed, as not raising a substantial federal question, a case in which the appellant specifically challenged the continuing validity of Leland v. Oregon. This occurred in Rivera v. Delaware, 429 U.S. 877 (1976), an appeal from a Delaware conviction which, in reliance on Leland, had been affirmed by the Delaware Supreme Court over the claim that the Delaware statute was unconstitutional because it burdened the defendant with proving his affirmative defense of insanity by a preponderance of the evidence. The claim in this Court was that Leland had been overruled by Winship and Mullaney. We dismissed the appeal as not presenting a substantial federal question. Cf. Hicks v. Miranda, 422 U.S. 332, 344 (1975).
We cannot conclude that Patterson's conviction under the New York law deprived him of due process of law. The crime of murder is defined by the statute, which represents a recent revision of the state criminal code, as causing the death of another person with intent to do so. The death, the intent to kill, and causation are the facts that the State is required to prove beyond a reasonable doubt if a person is to be convicted of murder. No further facts are either presumed or inferred [432 U.S. 197, 206] in order to constitute the crime. The statute does provide an affirmative defense - that the defendant acted under the influence of extreme emotional disturbance for which there was a reasonable explanation - which, if proved by a preponderance of the evidence, would reduce the crime to manslaughter, an offense defined in a separate section of the statute. It is plain enough that if the intentional killing is shown, the State intends to deal with the defendant as a murderer unless he demonstrates the mitigating circumstances.
Here, the jury was instructed in accordance with the statute, and the guilty verdict confirms that the State successfully carried its burden of proving the facts of the crime beyond a reasonable doubt. Nothing in the evidence, including any evidence that might have been offered with respect to Patterson's mental state at the time of the crime, raised a reasonable doubt about his guilt as a murderer; and clearly the evidence failed to convince the jury that Patterson's affirmative defense had been made out. It seems to us that the State satisfied the mandate of Winship that it prove beyond a reasonable doubt "every fact necessary to constitute the crime with which [Patterson was] charged." 397 U.S., at 364 .
In convicting Patterson under its murder statute, New York did no more than Leland and Rivera permitted it to do without violating the Due Process Clause. Under those cases, once the facts constituting a crime are established beyond a reasonable doubt, based on all the evidence including the evidence of the defendant's mental state, the State may refuse to sustain the affirmative defense of insanity unless demonstrated by a preponderance of the evidence.
The New York law on extreme emotional disturbance follows this pattern. This affirmative defense, which the Court of Appeals described as permitting "the defendant to show that his actions were caused by a mental infirmity not arising to the level of insanity, and that he is less culpable for having committed them," 39 N. Y. 2d, at 302, 347 N. E. 2d, at 907, [432 U.S. 197, 207] does not serve to negative any facts of the crime which the State is to prove in order to convict of murder. It constitutes a separate issue on which the defendant is required to carry the burden of persuasion; and unless we are to overturn Leland and Rivera, New York has not violated the Due Process Clause, and Patterson's conviction must be sustained.
We are unwilling to reconsider Leland and Rivera. But even if we were to hold that a State must prove sanity to convict once that fact is put in issue, it would not necessarily follow that a State must prove beyond a reasonable doubt every fact, the existence or nonexistence of which it is willing to recognize as an exculpatory or mitigating circumstance affecting the degree of culpability or the severity of the punishment. Here, in revising its criminal code, New York provided the affirmative defense of extreme emotional disturbance, a substantially expanded version of the older heat-of-passion concept; but it was willing to do so only if the facts making out the defense were established by the defendant with sufficient certainty. The State was itself unwilling to undertake to establish the absence of those facts beyond a reasonable doubt, perhaps fearing that proof would be too difficult and that too many persons deserving treatment as murderers would escape that punishment if the evidence need merely raise a reasonable doubt about the defendant's emotional state. It has been said that the new criminal code of New York contains some 25 affirmative defenses which exculpate or mitigate but which must be established by the defendant to be operative. 10 The Due Process Clause, as we see it, does not [432 U.S. 197, 208] put New York to the choice of abandoning those defenses or undertaking to disprove their existence in order to convict of a crime which otherwise is within its constitutional powers to sanction by substantial punishment.
The requirement of proof beyond a reasonable doubt in a criminal case is "bottomed on a fundamental value determination of our society that it is far worse to convict an innocent man than to let a guilty man go free." Winship, 397 U.S., at 372 (Harlan, J., concurring). The social cost of placing the burden on the prosecution to prove guilt beyond a reasonable doubt is thus an increased risk that the guilty will go free. While it is clear that our society has willingly chosen to bear a substantial burden in order to protect the innocent, it is equally clear that the risk it must bear is not without limits; and Mr. Justice Harlan's aphorism provides little guidance for determining what those limits are. Due process does not require that every conceivable step be taken, at whatever cost, to eliminate the possibility of convicting an innocent person. Punishment of those found guilty by a jury, for example, is not forbidden merely because there is a remote possibility in some instances that an innocent person might go to jail.
It is said that the common-law rule permits a State to [432 U.S. 197, 209] punish one as a murderer when it is as likely as not that he acted in the heat of passion or under severe emotional distress and when, if he did, he is guilty only of manslaughter. But this has always been the case in those jurisdictions adhering to the traditional rule. It is also very likely true that fewer convictions of murder would occur if New York were required to negative the affirmative defense at issue here. But in each instance of a murder conviction under the present law, New York will have proved beyond a reasonable doubt that the defendant has intentionally killed another person, an act which it is not disputed the State may constitutionally criminalize and punish. If the State nevertheless chooses to recognize a factor that mitigates the degree of criminality or punishment, we think the State may assure itself that the fact has been established with reasonable certainty. To recognize at all a mitigating circumstance does not require the State to prove its nonexistence in each case in which the fact is put in issue, if in its judgment this would be too cumbersome, too expensive, and too inaccurate. 11 [432 U.S. 197, 210]
We thus decline to adopt as a constitutional imperative, operative countrywide, that a State must disprove beyond a reasonable doubt every fact constituting any and all affirmative defenses related to the culpability of an accused. Traditionally, due process has required that only the most basic procedural safeguards be observed; more subtle balancing of society's interests against those of the accused have been left to the legislative branch. We therefore will not disturb the balance struck in previous cases holding that the Due Process Clause requires the prosecution to prove beyond a reasonable doubt all of the elements included in the definition of the offense of which the defendant is charged. Proof of the non-existence of all affirmative defenses has never been constitutionally required; and we perceive no reason to fashion such a rule in this case and apply it to the statutory defense at issue here.
This view may seem to permit state legislatures to reallocate burdens of proof by labeling as affirmative defenses at least some elements of the crimes now defined in their statutes. But there are obviously constitutional limits beyond which the States may not go in this regard. "[I]t is not within the province of a legislature to declare an individual guilty or presumptively guilty of a crime." McFarland v. American Sugar Rfg. Co., 241 U.S. 79, 86 (1916). The legislature cannot "validly command that the finding of an indictment, or mere proof of the identity of the accused, should create a presumption of the existence of all the facts essential to guilt." Tot v. United States, 319 U.S. 463, 469 (1943). See also Speiser v. Randall, 357 U.S., at 523 -525. Morrison v. California, 291 U.S. 82 (1934), also makes the point with sufficient clarity. [432 U.S. 197, 211]
Long before Winship, the universal rule in this country was that the prosecution must prove guilt beyond a reasonable doubt. At the same time, the long-accepted rule was that it was constitutionally permissible to provide that various affirmative defenses were to be proved by the defendant. This did not lead to such abuses or to such widespread redefinition of crime and reduction of the prosecution's burden that a new constitutional rule was required. 12 This was not the problem to which Winship was addressed. Nor does the fact that a majority of the States have now assumed the burden of disproving affirmative defenses - for whatever reasons - mean that those States that strike a different balance are in violation of the Constitution. 13 [432 U.S. 197, 212]
It is urged that Mullaney v. Wilbur necessarily invalidates Patterson's conviction. In Mullaney the charge was murder, 14 which the Maine statute defined as the unlawful killing of a human being "with malice aforethought, either express or implied." The trial court instructed the jury that the words "malice aforethought" were most important because "malice [432 U.S. 197, 213] aforethought is an essential and indispensable element of the crime of murder." Malice, as the statute indicated and as the court instructed, could be implied and was to be implied from "any deliberate, cruel act committed by one person against another suddenly . . . or without a considerable provocation," in which event an intentional killing was murder unless by a preponderance of the evidence it was shown that the act was committed "in the heat of passion, on sudden provocation." The instructions emphasized that "`malice aforethought and heat of passion on sudden provocation are two inconsistent things'; thus, by proving the latter the defendant would negate the former." 421 U.S., at 686 -687 (citation omitted).
Wilbur's conviction, which followed, was affirmed. The Maine Supreme Judicial Court held that murder and manslaughter were varying degrees of the crime of felonious homicide and that the presumption of malice arising from the unlawful killing was a mere policy presumption operating to cast on the defendant the burden of proving provocation if he was to be found guilty of manslaughter rather than murder - a burden which the Maine law had allocated to him at least since the mid-1800's.
The Court of Appeals for the First Circuit then ordered that a writ of habeas corpus issue, holding that the presumption unconstitutionally shifted to the defendant the burden of proof with respect to an essential element of the crime. The Maine Supreme Judicial Court disputed this interpretation of Maine law in State v. Lafferty, 309 A. 2d 647 (1973), declaring that malice aforethought, in the sense of premeditation, was not an element of the crime of murder and that the federal court had erroneously equated the presumption of malice with a presumption of premeditation.
Mullaney's holding, it is argued, is that the State may not permit the blameworthiness of an act or the severity of punishment authorized for its commission to depend on the presence or absence of an identified fact without assuming the burden of proving the presence or absence of that fact, as the case may be, beyond a reasonable doubt. 15 In our view, [432 U.S. 197, 215] the Mullaney holding should not be so broadly read. The concurrence of two Justices in Mullaney was necessarily contrary to such a reading; and a majority of the Court refused to so understand and apply Mullaney when Rivera was dismissed for want of a substantial federal question.
Mullaney surely held that a State must prove every ingredient of an offense beyond a reasonable doubt, and that it may not shift the burden of proof to the defendant by presuming that ingredient upon proof of the other elements of the offense. This is true even though the State's practice, as in Maine, had been traditionally to the contrary. Such shifting of the burden of persuasion with respect to a fact which the State deems so important that it must be either proved or presumed is impermissible under the Due Process Clause.
It was unnecessary to go further in Mullaney. The Maine Supreme Judicial Court made it clear that malice aforethought, which was mentioned in the statutory definition of the crime, was not equivalent to premeditation and that the presumption of malice traditionally arising in intentional homicide cases carried no factual meaning insofar as premeditation was concerned. Even so, a killing became murder in Maine when it resulted from a deliberate, cruel act committed by one person against another, "suddenly without any, or without a considerable provocation." State v. Lafferty, supra, at 665. Premeditation was not within the definition of murder; but [432 U.S. 197, 216] malice, in the sense of the absence of provocation, was part of the definition of that crime. Yet malice, i. e., lack of provocation, was presumed and could be rebutted by the defendant only by proving by a preponderance of the evidence that he acted with heat of passion upon sudden provocation. In Mullaney we held that however traditional this mode of proceeding might have been, it is contrary to the Due Process Clause as construed in Winship.
As we have explained, nothing was presumed or implied against Patterson; and his conviction is not invalid under any of our prior cases. The judgment of the New York Court of Appeals is
[ Footnote 2 ] Section 125.25 provides in relevant part:
[ Footnote 3 ] Section 125.20 (2), N. Y. Penal Law 125.20 (2) (McKinney 1975), provides:
[ Footnote 4 ] Appellant also contended at trial that the shooting was accidental and that therefore he had no intent to kill Northrup. It is here undisputed, however, that the prosecution proved beyond a reasonable doubt that the killing was intentional.
[ Footnote 5 ] The trial court's instructions to the jury focused emphatically and repeatedly on the prosecution's burden of proving guilt beyond a reasonable doubt.
[ Footnote 6 ] In Hankerson v. North Carolina, post, p. 233, we hold, as did the New York Court of Appeals in the present case, that Mullaney is to be applied retroactively. The fact that Patterson was tried prior to our decision in Mullaney does not insulate this case from the principles of Mullaney.
[ Footnote 7 ] See also F. Wharton, A Treatise on the Law of Evidence in Criminal Issues 240-269 (9th ed. 1884); H. Kelley, Criminal Law and Practice 124-128, 131 (1876); Fletcher, Two Kinds of Legal Rules: A Comparative Study of Burden-of-Persuasion Practices in Criminal Cases, 77 Yale L. J. 880, 882-884 (1968); Note, Affirmative Defenses After Mullaney v. Wilbur: New York's Extreme Emotional Disturbance, 43 Brooklyn L. Rev. 171, 190 (1976).
[ Footnote 8 ] York, which relied on American authorities dating back to the early 1800's, confirmed that the common-law and prevailing American view was that the burden was on the defendant to prove provocation. York is said to have governed a half century of American burden-of-proof decisions in provocation and self-defense cases. Fletcher, supra, n. 7, at 903-904.
[ Footnote 9 ] Meanwhile, the Court had explained that although the State could go too far in shifting the burden of proof to a defendant in a criminal case, the Due Process Clause did not invalidate every instance of burdening the defendant with proving an exculpatory fact. In Morrison v. California, 291 U.S. 82 (1934), a state law made it illegal for an alien ineligible for citizenship to own or possess land. Initially, in a summary dismissal for want of a substantial federal question, Morrison v. California, 288 U.S. 591 (1933), the Court held that it did not violate the Due Process Clause for the State to place on the defendant "the burden of proving citizenship as a defense," 291 U.S., at 88 , once the State's evidence had shown that the defendant possessed the land and was a member of a race barred from citizenship. In the later Morrison case the Court reiterated and approved its previous summary holding, even though it struck down more drastic burden shifting permitted under another section of the statute. The Court said that its earlier per curiam ruling "was not novel":
[ Footnote 10 ] The State of New York is not alone in this result:
[ Footnote 11 ] The drafters of the Model Penal Code would, as a matter of policy, place the burden of proving the nonexistence of most affirmative defenses, including the defense involved in this case, on the prosecution once the defendant has come forward with some evidence that the defense is present. The drafters recognize the need for flexibility, however, and would, in "some exceptional situations," place the burden of persuasion on the accused.
[ Footnote 12 ] Whenever due process guarantees are dependent upon the law as defined by the legislative branches, some consideration must be given to the possibility that legislative discretion may be abused to the detriment of the individual. See Mullaney v. Wilbur, 421 U.S., at 698 -699. The applicability of the reasonable-doubt standard, however, has always been dependent on how a State defines the offense that is charged in any given case; yet there has been no great rush by the States to shift the burden of disproving traditional elements of the criminal offenses to the accused.
[ Footnote 13 ] As Chief Judge Breitel cogently stated in concurring in the judgment and opinion below:
[ Footnote 14 ] The defendant in Mullaney was convicted under Me. Rev. Stat. Ann., Tit. 17, 2651 (1964), which provided:
[ Footnote 15 ] There is some language in Mullaney that has been understood as perhaps construing the Due Process Clause to require the prosecution to prove beyond a reasonable doubt any fact affecting "the degree of criminal culpability." See, e. g., Note, Affirmative Defenses After Mullaney v. Wilbur: New York's Extreme Emotional Disturbance, 43 Brooklyn L. Rev. 171 (1976); Note, Affirmative Defenses in Ohio After Mullaney v. Wilbur, 36 Ohio St. L. J. 828 (1975); Comment, Unburdening the Criminal Defendant: Mullaney v. Wilbur and the Reasonable Doubt Standard, 11 Harv. Civ. Rights-Civ. Lib. L. Rev. 390 (1976). It is said that such [432 U.S. 197, 215] a rule would deprive legislatures of any discretion whatsoever in allocating the burden of proof, the practical effect of which might be to undermine legislative reform of our criminal justice system. See Part II, supra; Low & Jeffries, supra, n. 10. Carried to its logical extreme, such a reading of Mullaney might also, for example, discourage Congress from enacting pending legislation to change the felony-murder rule by permitting the accused to prove by a preponderance of the evidence the affirmative defense that the homicide committed was neither a necessary nor a reasonably foreseeable consequence of the underlying felony. See Senate bill S. 1, 94th Cong., 1st Sess., 118 (1975). The Court did not intend Mullaney to have such far-reaching effect.
MR. JUSTICE POWELL, with whom MR. JUSTICE BRENNAN and MR. JUSTICE MARSHALL join, dissenting.
In the name of preserving legislative flexibility, the Court today drains In re Winship, 397 U.S. 358 (1970), of much of its vitality. Legislatures do require broad discretion in the drafting of criminal laws, but the Court surrenders to the legislative branch a significant part of its responsibility to protect the presumption of innocence.
An understanding of the import of today's decision requires a comparison of the statutes at issue here with the statutes and practices of Maine struck down by a unanimous Court just two years ago in Mullaney v. Wilbur, 421 U.S. 684 (1975).
Maine's homicide laws embodied the common-law distinctions along with the colorful common-law language. Murder [432 U.S. 197, 217] was defined in the statute as the unlawful killing of a human being "with malice aforethought, either express or implied." Manslaughter was a killing "in the heat of passion, on sudden provocation, without express or implied malice aforethought." Id., at 686, and n. 3. Although "express malice" at one point may have had its own significant independent meaning, see Perkins, A Re-Examination of Malice Aforethought, 43 Yale L. J. 537, 546-552 (1934), in practice a finding that the killing was committed with malice aforethought had come to mean simply that heat of passion was absent. Indeed, the trial court in Mullaney expressly charged the jury that "malice aforethought and heat of passion on sudden provocation are two inconsistent things." 421 U.S., at 686 -687. And the Maine Supreme Judicial Court had held that instructions concerning express malice (in the sense of premeditation) were unnecessary. The only inquiry for the jury in deciding whether a homicide amounted to murder or manslaughter was the inquiry into heat of passion on sudden provocation. State v. Lafferty, 309 A. 2d 647, 664-665 (Me. 1973). See 421 U.S., at 686 n. 4.
Our holding in Mullaney found no constitutional defect in these statutory provisions. Rather, the defect in Maine practice lay in its allocation of the burden of persuasion with respect to the crucial factor distinguishing murder from manslaughter. In Maine, juries were instructed that if the prosecution proved that the homicide was both intentional and unlawful, the crime was to be considered murder unless the defendant proved by a preponderance of the evidence that he acted in the heat of passion on sudden provocation. Only if the defendant carried this burden would the offense be reduced to manslaughter.
New York's present homicide laws had their genesis in lingering dissatisfaction with certain aspects of the common-law framework that this Court confronted in Mullaney. Critics charged that the archaic language tended to obscure the factors [432 U.S. 197, 218] of real importance in the jury's decision. Also, only a limited range of aggravations would lead to mitigation under the common-law formula, usually only those resulting from direct provocation by the victim himself. It was thought that actors whose emotions were stirred by other forms of outrageous conduct, even conduct by someone other than the ultimate victim, also should be punished as manslaughterers rather than murderers. Moreover, the common-law formula was generally applied with rather strict objectivity. Only provocations that might cause the hypothetical reasonable man to lose control could be considered. And even provocations of that sort were inadequate to reduce the crime to manslaughter if enough time had passed for the reasonable man's passions to cool, regardless of whether the actor's own thermometer had registered any decline. See generally W. LaFave & A. Scott, Criminal Law 528-530, 539-540, 571-582 (1972); Wechsler, Codification of Criminal Law in the United States: The Model Penal Code, 68 Colum. L. Rev. 1425, 1446 (1968); ALI, Model Penal Code 201.3, Comment (Tent. Draft No. 9, 1959); Perkins, supra. Cf. B. Cardozo, Law and Literature and Other Essays 99-101 (1931).
The American Law Institute took the lead in moving to remedy these difficulties. As part of its commendable undertaking to prepare a Model Penal Code, it endeavored to bring modern insights to bear on the law of homicide. The result was a proposal to replace "heat of passion" with the moderately broader concept of "extreme mental or emotional disturbance." The proposal first appeared in a tentative draft published in 1959, and it was accepted by the Institute and included as 210.3 of the 1962 Proposed Official Draft.
At about this time the New York Legislature undertook the preparation of a new criminal code, and the Revised Penal Law of 1967 was the ultimate result. The new code adopted virtually word for word the ALI formula for distinguishing murder from manslaughter. N. Y. Penal Law 125.20 (2), [432 U.S. 197, 219] 125.25 (1) (a) (McKinney 1975). 1 Under current New York law, 2 those who kill intentionally are guilty of murder. But there is an affirmative defense left open to a defendant: If his act was committed "under the influence of extreme emotional disturbance for which there was a reasonable explanation or excuse," the crime is reduced to manslaughter. The supposed defects of a formulation like Maine's have been removed. Some of the rigid objectivity of the common law is relieved, since reasonableness is to be determined "from the viewpoint of a person in the defendant's situation under the circumstances [432 U.S. 197, 220] as the defendant believed them to be." 125.25 (1) (a). The New York law also permits mitigation when emotional disturbance results from situations other than direct provocation by the victim. And the last traces of confusing archaic language have been removed. There is no mention of malice aforethought, no attempt to give a name to the state of mind that exists when extreme emotional disturbance is not present. The statute is framed in lean prose modeled after the ALI approach, giving operative descriptions of the crucial factors rather than attempting to attach the classical labels.
Despite these changes, the major factor that distinguishes murder from manslaughter in New York - "extreme emotional disturbance" - is undeniably the modern equivalent of "heat of passion." The ALI drafters made this abundantly clear. They were not rejecting the notion that some of those who kill in an emotional outburst deserve lesser punishment; they were merely refining the concept to relieve some of the problems with the classical formulation. See ALI, Model Penal Code, 201.3, Comment, pp. 46-48 (Tent. Draft No. 9, 1959). The New York drafters left no doubt about their reliance on the ALI work. See 39 N. Y. 2d 288, 300-301, 347 N. E. 2d 898, 906 (1976). Both the majority and the dissenters in the New York Court of Appeals agreed that extreme emotional disturbance is simply "a new formulation" for the traditional language of heat of passion. Id., at 301, 347 N. E. 2d, at 906; id., at 312, 347 N. E. 2d, at 913-914 (Cooke, J., dissenting).
But in one important respect the New York drafters chose to parallel Maine's practice precisely, departing markedly from the ALI recommendation. Under the Model Penal Code the prosecution must prove the absence of emotional disturbance beyond a reasonable doubt once the issue is properly raised. See ALI, Model Penal Code 1.12, 210.3 (proposed Official Draft 1962); id., 1.13, Comment, pp. 108-118 (Tent. Draft No. 4, 1955). In New York, however, extreme emotional disturbance constitutes an affirmative defense rather [432 U.S. 197, 221] than a simple defense. Consequently the defendant bears not only the burden of production on this issue; he has the burden of persuasion as well. N. Y. Penal Law 25.00 (McKinney 1975).
Mullaney held invalid Maine's requirement that the defendant prove heat of passion. The Court today, without disavowing the unanimous holding of Mullaney, approves New York's requirement that the defendant prove extreme emotional disturbance. The Court manages to run a constitutional boundary line through the barely visible space that separates Maine's law from New York's. It does so on the basis of distinctions in language that are formalistic rather than substantive.
This result is achieved by a narrowly literal parsing of the holding in Winship: "[T]he Due Process Clause protects the accused against conviction except upon proof beyond a reasonable doubt of every fact necessary to constitute the crime with which he is charged." 397 U.S., at 364 . The only "facts" necessary to constitute a crime are said to be those that appear on the face of the statute as a part of the definition of the crime. 3 Maine's statute was invalid, the Court reasons, because it "defined [murder] as the unlawful killing of a human being `with malice aforethought, either express or implied.'" Ante, at 212. "[M]alice," the Court reiterates, "in the sense of the absence of provocation, was part of the definition of that crime." Ante, at 216. Winship was violated only because this "fact" - malice - was "presumed" unless the defendant persuaded the jury otherwise by showing that he acted in the heat of passion. 4 New York, in form presuming [432 U.S. 197, 222] no affirmative "fact" against Patterson, 5 and blessed with a statute drafted in the leaner language of the 20th century, escapes constitutional scrutiny unscathed even though the effect on the defendant of New York's placement of the burden of persuasion is exactly the same as Maine's. See 39 N. Y. 2d, at 312-313, 347 N. E. 2d, at 913-914 (Cooke, J., dissenting).
This explanation of the Mullaney holding bears little resemblance [432 U.S. 197, 223] to the basic rationale of that decision. 6 But this is not the cause of greatest concern. The test the Court today establishes allows a legislature to shift, virtually at will, the burden of persuasion with respect to any factor in a criminal case, so long as it is careful not to mention the nonexistence of that factor in the statutory language that defines the crime. The sole requirement is that any references to the factor be confined to those sections that provide for an affirmative defense. 7
Perhaps the Court's interpretation of Winship is consistent with the letter of the holding in that case. But little of the spirit survives. Indeed, the Court scarcely could distinguish this case from Mullaney without closing its eyes to the constitutional values for which Winship stands. As Mr. Justice Harlan observed in Winship, "a standard of proof represents an attempt to instruct the factfinder concerning the degree of [432 U.S. 197, 224] confidence our society thinks he should have in the correctness of factual conclusions for a particular type of adjudication." 397 U.S., at 370 (concurring opinion). See Speiser v. Randall, 357 U.S. 513, 525 -526 (1958). Explaining Mullaney, the Court says today, in effect, that society demands full confidence before a Maine factfinder determines that heat of passion is missing - a demand so insistent that this Court invoked the Constitution to enforce it over the contrary decision by the State. But we are told that society is willing to tolerate far less confidence in New York's factual determination of precisely the same functional issue. One must ask what possibly could explain this difference in society demands. According to the Court, it is because Maine happened to attach a name - "malice aforethought" - to the absence of heat of passion, whereas New York refrained from giving a name to the absence of extreme emotional disturbance. See 39 N. Y. 2d, at 313, 347 N. E. 2d, at 914 (Cooke, J., dissenting).
With all respect, this type of constitutional adjudication is indefensibly formalistic. A limited but significant check on possible abuses in the criminal law now becomes an exercise in arid formalities. What Winship and Mullaney had sought to teach about the limits a free society places on its procedures to safeguard the liberty of its citizens becomes a rather simplistic lesson in statutory draftsmanship. Nothing in the Court's opinion prevents a legislature from applying this new learning to many of the classical elements of the crimes it punishes. 8 It would be preferable, if the Court has found [432 U.S. 197, 225] reason to reject the rationale of Winship and Mullaney, simply and straightforwardly to overrule those precedents.
The Court understandably manifests some uneasiness that its formalistic approach will give legislatures too much latitude in shifting the burden of persuasion. And so it issues a warning that "there are obviously constitutional limits beyond which the States may not go in this regard." Ante, at 210. The Court thereby concedes that legislative abuses may occur and that they must be curbed by the judicial branch. But if the State is careful to conform to the drafting formulas articulated today, the constitutional limits are anything but "obvious." This decision simply leaves us without a conceptual framework for distinguishing abuses from legitimate legislative adjustments of the burden of persuasion in criminal cases. 9
It is unnecessary for the Court to retreat to a formalistic test for applying Winship. Careful attention to the Mullaney decision reveals the principles that should control in this and like cases. Winship held that the prosecution must bear the burden of proving beyond a reasonable doubt "`the existence of every fact necessary to constitute the crime charged.'" 397 U.S., at 363 , quoting Davis v. United States, 160 U.S. 469, 493 (1895). In Mullaney we concluded that heat of passion was one of the "facts" described in Winship - that is, a [432 U.S. 197, 226] factor as to which the prosecution must bear the burden of persuasion beyond a reasonable doubt. 421 U.S., at 704 . We reached that result only after making two careful inquiries. First, we noted that the presence or absence of heat of passion made a substantial difference in punishment of the offender and in the stigma associated with the conviction. Id., at 697-701. Second, we reviewed the history, in England and this country, of the factor at issue. Id., at 692-696. Central to the holding in Mullaney was our conclusion that heat of passion "has been, almost from the inception of the common law of homicide, the single most important factor in determining the degree of culpability attaching to an unlawful homicide." Id., at 696.
Implicit in these two inquiries are the principles that should govern this case. The Due Process Clause requires that the prosecutor bear the burden of persuasion beyond a reasonable doubt only if the factor at issue makes a substantial difference in punishment and stigma. The requirement of course applies a fortiori if the factor makes the difference between guilt and innocence. But a substantial difference in punishment alone is not enough. It also must be shown that in the Anglo-American legal tradition 10 the factor in question historically has held that level of importance. 11 If either branch [432 U.S. 197, 227] of the test is not met, then the legislature retains its traditional authority over matters of proof. But to permit a shift in the burden of persuasion when both branches of this test are satisfied would invite the undermining of the presumption of innocence, "that bedrock `axiomatic and elementary' principle whose `enforcement lies at the foundation of the administration of our criminal law.'" In re Winship, 397 U.S., at 363 , quoting from Coffin v. United States, 156 U.S. 432, 453 (1895). See Cool v. United States, 409 U.S. 100, 104 (1972); Ivan V. v. City of New York, 407 U.S. 203, 204 (1972); Lego v. Twomey, 404 U.S. 477, 486 -487 (1972); Morissette v. United States, 342 U.S. 246, 275 (1952); Bailey v. Alabama, 219 U.S. 219, 236 (1911); Davis v. United States, supra. This is not a test that rests on empty form, for "Winship is concerned with substance rather than . . . formalism." Mullaney v. Wilbur, 421 U.S., at 699 .
I hardly need add that New York's provisions allocating the burden of persuasion as to "extreme emotional disturbance" are unconstitutional when judged by these standards. "Extreme emotional disturbance" is, as the Court of Appeals recognized, the direct descendant of the "heat of passion" factor considered at length in Mullaney. I recognize, of course, that the differences between Maine and New York law are not unimportant to the defendant; there is a somewhat broader opportunity for mitigation. But none of those distinctions is relevant here. The presence or absence of extreme emotional disturbance makes a critical difference in punishment and stigma, and throughout our history the resolution of this issue of fact, although expressed in somewhat different terms, has distinguished manslaughter from murder. See 4 W. Blackstone, Commentaries *190-193, 198-201.
The Court beats its retreat from Winship apparently because of a concern that otherwise the federal judiciary will intrude [432 U.S. 197, 228] too far into substantive choices concerning the content of a State's criminal law. 12 The concern is legitimate, see generally Powell v. Texas, 392 U.S. 514, 533 -534 (1968) (plurality opinion); Leland v. Oregon, 343 U.S. 790, 803 (1952) (Frankfurter, J., dissenting), but misplaced. Winship and Mullaney are no more than what they purport to be: decisions addressing the procedural requirements that States must meet to comply with due process. They are not outposts for policing the substantive boundaries of the criminal law.
The Winship/Mullaney test identifies those factors of such importance, historically, in determining punishment and stigma that the Constitution forbids shifting to the defendant the burden of persuasion when such a factor is at issue. Winship and Mullaney specify only the procedure that is required when a State elects to use such a factor as part of its substantive criminal law. They do not say that the State must elect to use it. For example, where a State has chosen to retain the traditional distinction between murder and manslaughter, as have New York and Maine, the burden of persuasion must remain on the prosecution with respect to the distinguishing factor, in view of its decisive historical importance. But nothing in Mullaney or Winship precludes a State from abolishing the distinction between murder and manslaughter and treating all unjustifiable homicide as murder. 13 In this significant [432 U.S. 197, 229] respect, neither Winship nor Mullaney eliminates the substantive flexibility that should remain in legislative hands.
Moreover, it is unlikely that more than a few factors - although important ones - for which a shift in the burden of persuasion seriously would be considered will come within the Mullaney holding. With some exceptions, then, the State has the authority "to recognize a factor that mitigates the degree of criminality or punishment" without having "to prove its nonexistence in each case in which the fact is put in issue." Ante, at 209. New ameliorative affirmative defenses, 14 about [432 U.S. 197, 230] which the Court expresses concern, generally remain undisturbed by the holdings in Winship and Mullaney - and need not be disturbed by a sound holding reversing Patterson's conviction. 15
Furthermore, as we indicated in Mullaney, 421 U.S., at 701 -702, n. 28, even as to those factors upon which the prosecution must bear the burden of persuasion, the State retains an important procedural device to avoid jury confusion and prevent the prosecution from being unduly hampered. The State normally may shift to the defendant the burden of production, 16 that is, the burden of going forward with sufficient [432 U.S. 197, 231] evidence "to justify [a reasonable] doubt upon the issue." 17 ALI, Model Penal Code 1.13, Comment, p. 110 (Tent. Draft No. 4, 1955). If the defendant's evidence does not cross this threshold, the issue - be it malice, extreme emotional disturbance, self-defense, or whatever - will not be submitted to the jury. 18 See Sansone v. United States, 380 U.S. 343, 349 (1965); Stevenson v. United States, 162 U.S. 313, 314 -316 (1896). Ever since this Court's decision in Davis v. United States, 160 U.S. 469 (1895), federal prosecutors have borne the burden of persuasion with respect to factors like insanity, self-defense, and malice or provocation, once the defendant has carried this burden of production. See, e. g., Blake v. United States, 407 F.2d 908, 910-911 (CA5 1969) (en banc) (insanity); Frank v. United States, 42 F.2d 623, 629 (CA9 1930) (self-defense); United States v. Alexander, 152 U.S. App. D.C. 371, 389-395, 471 F.2d 923, 941-947, cert. denied sub nom. Murdock v. United States, 409 U.S. 1044 (1972) (provocation). I know of no indication that this [432 U.S. 197, 232] practice has proven a noticeable handicap to effective law enforcement. 19
To be sure, there will be many instances when the Winship/Mullaney test as I perceive it will be more difficult to apply than the Court's formula. Where I see the need for a careful and discriminating review of history, the Court finds a brightline standard that can be applied with a quick glance at the face of the statute. But this facile test invites tinkering with the procedural safeguards of the presumption of innocence, an invitation to disregard the principles of Winship that I would not extend.
[ Footnote 1 ] There are also other forms of manslaughter set forth in the New York statute, not all of which conform to the ALI recommendations. Those provisions are not implicated in this case.
[ Footnote 2 ] The 1967 provisions marked a considerable departure from the prior New York statutes defining manslaughter. As we noted in Mullaney v. Wilbur, 421 U.S. 684, 694 (1975), the grounds for distinguishing murder from manslaughter developed along two distinct paths in this country. Prior to the 1967 change New York, with a handful of other jurisdictions, see ALI, Model Penal Code 201.3, Comment, p. 43 (Tent. Draft No. 9, 1959), pursued the first path: to establish malice (and hence to convict of murder) the prosecution bore the burden of persuasion, being required to establish a substantive element of intent - that the defendant possessed "a design to effect death." See 39 N. Y. 2d 288, 299, 347 N. E. 2d 898, 905 (1976) (case below); Stokes v. People, 53 N. Y. 164 (1873). Maine, in contrast, followed the second path, marked out most prominently by Chief Justice Shaw's opinion in Commonwealth v. York, 50 Mass. 93 (1845): malice was presumed unless the defendant established that he acted in the heat of passion.
This difference between the old New York practice and the York approach was substantial - as noted by the Court of Appeals below. But that court placed entirely too much weight on this distinction as a basis for concluding that Mullaney's holding was inapplicable. The statute at issue here is the 1967 Revised Penal Law, not the earlier formulation. In 1967, New York broke from the first branch and aligned itself with York, although casting its statute in more modern language. No matter how extensive the differences between the pre-1967 practice and the Maine statutes found deficient in Mullaney, this case must be decided on the basis of current New York law.
[ Footnote 3 ] The Court holds that the prosecution must prove beyond a reasonable doubt "all of the elements included in the definition of the offense of which the defendant is charged." Ante, at 210 (emphasis added).
[ Footnote 4 ] The Court explains: "Such shifting of the burden of persuasion with respect to a fact which the State deems so important that it must be [432 U.S. 197, 222] either proved or presumed is impressible under the Due Process Clause." Ante, at 215. I must point out, however, that this is a less than faithful reading of Maine law. The Maine Supreme Judicial Court, rejecting a recent holding to the contrary by the Court of Appeals for the First Circuit, emphatically insisted that the words "malice aforethought" appearing in the Maine statute did not connote a "fact" to be "presumed" in the sense the latter terms are customarily used:
[ Footnote 5 ] "The crime of murder is defined by the [New York] statute . . . as causing the death of another person with intent to do so. The death, the intent to kill, and causation are the facts that the State is required to prove beyond a reasonable doubt if a person is to be convicted of murder. No further facts are either presumed or inferred in order to constitute the crime. . . .
[ Footnote 6 ] In Mullaney we made it clear that Winship is not "limited to a State's definition of the elements of a crime." 421 U.S., at 699 n. 24.
[ Footnote 7 ] Although the Court never says so explicitly, its new standards appear to be designed for application to the language of a criminal statute on its face, regardless of how the state court construes the statute. The Court, in explaining Mullaney, persistently states that in Maine malice "was part of the definition of that crime [murder]," ante, at 216, even though the Maine Supreme Judicial Court, construing its own statute, had ruled squarely to the contrary. See n. 4, supra. In the usual case it is well established that an authoritative construction by the State's highest court "puts [appropriate] words in the statute as definitely as if it had been so amended by the legislature." Winters v. New York, 333 U.S. 507, 514 (1948). See Mullaney, supra, at 690-691; Hebert v. Louisiana, 272 U.S. 312, 316 -317 (1926); Murdock v. Memphis, 20 Wall. 590, 635 (1875). Why an apparent exception should be engrafted on that doctrine today goes unexplained.
The result, under the Court's holding, is that only the legislature can remedy any defects that come to light as a result of the Court's decision. No matter how clear the legislative intent that defendants bear the burden of persuasion on an issue - an ultimate result the Court approves - state courts may not effectuate that intent until the right verbal formula appears in the statute book.
[ Footnote 8 ] For example, a state statute could pass muster under the only solid standard that appears in the Court's opinion if it defined murder as mere physical contact between the defendant and the victim leading to the victim's death, but then set up an affirmative defense leaving it to the defendant to prove that he acted without culpable mens rea. The State, in other words, could be relieved altogether of responsibility for proving anything regarding the defendant's state of mind, provided only that the face of the statute meets the Court's drafting formulas.
To be sure, it is unlikely that legislatures will rewrite their criminal laws [432 U.S. 197, 225] in this extreme form. The Court seems to think this likelihood of restraint is an added reason for limiting review largely to formalistic examination. Ante, at 211. But it is completely foreign to this Court's responsibility for constitutional adjudication to limit the scope of judicial review because of the expectation - however reasonable - that legislative bodies will exercise appropriate restraint.
[ Footnote 9 ] I have no doubt that the Court would find some way to strike down a formalistically correct statute as egregious as the one hypothesized in n. 8, supra. Cf. Morissette v. United States, 342 U.S. 246, 250 -263 (1952). But today's ruling suggests no principled basis for concluding that such a statute falls outside the "obvious" constitutional limits the Court invokes.
[ Footnote 10 ] Cf. Brinegar v. United States, 338 U.S. 160, 174 (1949):
[ Footnote 11 ] As the Court acknowledges, ante, at 207-208, n. 10, the clear trend over the years has been to require the prosecutor to carry the burden of persuasion with respect to all important factors in a criminal case, including traditional affirmative defenses. See W. LaFave & A. Scott, Criminal Law 50 (1972); C. McCormick, Evidence 341, pp. 800-802 (1972).
[ Footnote 12 ] See Low & Jeffries, DICTA: Constitutionalizing the Criminal Law?, 29 Va. Law Weekly, No. 18, p. 1 (1977); Tushnet, Constitutional Limitation of Substantive Criminal Law: An Examination of the Meaning of Mullaney v. Wilbur, 55 B. U. L. Rev. 775 (1975).
[ Footnote 13 ] Perhaps under other principles of due process jurisprudence, certain factors are so fundamental that a State could not, as a substantive matter, refrain from recognizing them so long as it chooses to punish given conduct as a crime. Cf. Bailey v. Alabama, 219 U.S. 219 (1911) (holding a criminal-law presumption invalid procedurally and also finding a substantive defect under the Thirteenth Amendment and the Anti-Peonage Act). But substantive limits were not at issue in Winship or Mullaney, and they are not at issue here.
Even if there are no constitutional limits preventing the State, for [432 U.S. 197, 229] example, from treating all homicides as murders punishable equally regardless of mitigating factors like heat of passion or extreme emotional disturbance, the Winship/Mullaney rule still plays an important role. The State is then obliged to make its choices concerning the substantive content of its criminal laws with full awareness of the consequences, unable to mask substantive policy choices by shifts in the burden of persuasion. See Fletcher, Two Kinds of Legal Rules: A Comparative Study of Burden-of-Persuasion Practices in Criminal Cases, 77 Yale L. J. 880, 894 (1968) ("The burden of persuasion has proved to be a subtle, low-visibility tool for adjusting the interests of competing classes of litigants"). The political check on potentially harsh legislative action is then more likely to operate. Cf. Tot v. United States, 319 U.S. 463, 472 (1943); United States v. Romano, 382 U.S. 136 (1965).
Romano involved a challenge to a federal statute that authorized the jury to infer possession, custody, and control of an illegal still from mere presence at the site. The Government contended that the statute should be sustained since it was merely Congress' way of broadening the substantive provisions in order to make a crime of mere presence. The Court rejected this argument, serving notice that Congress could not work a substantive change of that magnitude in such a disguised form. Id., at 144. See Ashford & Risinger, Presumptions, Assumptions, and Due Process in Criminal Cases: A Theoretical Overview, 79 Yale L. J. 165, 177-178 (1969); Osenbaugh, The Constitutionality of Affirmative Defenses to Criminal Charges, 29 Ark. L. Rev. 429, 461 (1976).
[ Footnote 14 ] Numerous examples of such defenses are available: New York subjects an armed robber to lesser punishment than he would otherwise receive if he proves by a preponderance of the evidence that the gun he used was unloaded or inoperative. N. Y. Penal Law 160.15 (McKinney 1975). A number of States have ameliorated the usual operation of statutes [432 U.S. 197, 230] punishing statutory rape, recognizing a defense if the defendant shows that he reasonably believed his partner was of age. E. g., Ky. Rev. Stat. Ann. 500.070, 510.030 (1975); Wash. Rev. Code Ann. 9.79.160 (2) (Supp. 1975). Formerly the age of the minor was a strict-liability element of the crime. The Model Penal Code also employs such a shift in the burden of persuasion for a limited number of defenses. For example, a corporation can escape conviction of an offense if it proves by a pre-ponderance of the evidence that the responsible supervising officer exercised due diligence to prevent the commission of the offense. 2.07 (5) (Proposed Official Draft 1962).
[ Footnote 15 ] A number of commentators have suggested that the Constitution permits the States some latitude in adjusting the burden of persuasion with respect to new ameliorative affirmative defenses that result from legislative compromise, but not with respect to other factors. See, e. g., W. LaFave & A. Scott, supra, n. 11, at 49; 1 National Commission on Reform of Federal Criminal Laws, Working Papers 18-19 (1970); ALI, Model Penal Code 1.13, Comment, p. 113 (Tent. Draft No. 4, 1955) (quoted, ante, at 209 n. 11); Note, 51 Wash. L. Rev. 953, 964 (1976); Osenbaugh, supra, n. 13, at 459-467. Cf. Fletcher, supra, n. 13, at 928-929.
[ Footnote 16 ] There are outer limits on shifting the burden of production to a defendant, limits articulated in a long line of cases in this Court passing on the validity of presumptions. Most important are the "rational connection" requirement of Mobile, J. & K. C. R. Co. v. Turnipseed, 219 U.S. 35, 43 (1910), and Bailey v. Alabama, supra, at 238-239, and also the "comparative convenience" criterion of Morrison v. California, [432 U.S. 197, 231] 291 U.S. 82 (1934). See also, e. g., Tot v. United States, supra, at 467-468; Speiser v. Randall, 357 U.S. 513, 523 -524 (1958); Leary v. United States, 395 U.S. 6, 33 -34 (1969); Barnes v. United States, 412 U.S. 837, 843 (1973). Caution is appropriate, however, in generalizing about the application of any of these cases to a given procedural device, since the term "presumption" covers a broad range of procedural mechanisms having significantly different consequences for the defendant. See McCormick, n. 11, supra, at 802-806; Evans v. State, 28 Md. App. 640, 675-678, 349 A. 2d 300, 324-325 (1975).
[ Footnote 17 ] This does not mean that the defendant must introduce evidence in every case. In some instances the prosecution's case may contain sufficient evidence in support of the defendant's position to generate a jury issue.
[ Footnote 18 ] On many occasions this Court has sustained a trial court's refusal to submit an issue to the jury in a criminal case when the defendant failed to meet his burden of production. See, e. g., Sparf v. United States, 156 U.S. 51, 63 -64 (1895); Andersen v. United States, 170 U.S. 481, 510 -511 (1898); Battle v. United States, 209 U.S. 36, 38 (1908). Cf. Galloway v. United States, 319 U.S. 372, 395 (1943).
[ Footnote 19 ] Dean McCormick emphasized that the burden of production is "a critical and important mechanism in a jury trial." In his view, "this mechanism has far more influence upon the final outcome of cases than does the burden of persuasion, which has become very largely a matter of the technique of the wording of instructions to juries." C. McCormick, Evidence 307, pp. 638-639, and n. 2 (1st ed. 1954). Cf. Fletcher, supra, n. 13, at 930. [432 U.S. 197, 233]
