No. 75-6583
Supreme Court of the United States
October 12, 1976

The appeal is dismissed for want of a substantial federal question.
Mr. Justice BRENNAN, with whom Mr. Justice MARSHALL joins, dissenting.


1
Appellant was convicted by a jury of murder in the second degree in Delaware Superior Court. The Delaware Supreme Court reversed and remanded with instructions to strike the murder conviction but enter a judgment of conviction for manslaughter; the constitutionality of a Delaware statute that requires a criminal defendant raising an insanity defense to prove mental illness or defect by a preponderance of the evidence was sustained. The relevant sections of the Delaware Code provide:


2
"401. Mental illness or mental defect.


3
"(1) In any prosecution for an offense, it is an affirmative      defense that, at the time of the conduct charged, as a result      of mental illness or mental defect, the accused lacked      substantial capacity to appreciate the wrongfulness of his      conduct or lacked sufficient will power to choose whether he      would do the act or refrain from doing it.


4
"(2) If the defendant prevails in establishing the      affirmative defense provided in subsection (1) of this      section, the trier of facts shall return a verdict of 'not      guilty by reason of insanity.'


5
"s 304. Defendant's affirmative defenses; prove by      preponderance of evidence.


6
"(a) When a defense declared by this Criminal Code or by      another statute to be an affirmative defense is raised at      trial, the defendant has the burden of establishing it by a      preponderance of the evidence." Del.Code Ann., Tit. 11, § 401      (1975).

The Delaware Supreme Court held that Leland v. Oregon, 343 U.S. 790, 72 S.Ct. 1002, 96 L.Ed. 1302 (1952), required its conclusion, because Leland "has not been overruled by Mullaney (v. Wilbur, 421 U.S. 684, 95 S.Ct. 1881, 44 L.Ed.2d 508 (1975)), . . . either expressly or implicitly." 351 A.2d 561, 562 (1976). Because I believe this case presents the substantial federal question whether Leland can be reconciled with our recent holdings in In re Winship, 397 U.S. 358, 90 S.Ct. 1068, 25 L.Ed.2d 368 (1970), and Mullaney v. Wilbur, supra, I would note probable jurisdiction and set the case for oral argument.

Mr. Justice STEVENS would note probable jurisdiction and set the case for oral argument.

In Mullaney, we considered a Maine rule that placed upon a criminal defendant charged with murder the burden of proving by a preponderance of the evidence that he had acted in the heat of passion on sudden impulse in order to reduce the homicide to manslaughter. We concluded that this rule did not comport with the due process requirement, as defined in In re Winship, 397 U.S., at 361-364, 90 S.Ct. 1068, that the prosecution must prove beyond a reasonable doubt every fact necessary to constitute the crime charged. In reaching this conclusion, my Brother Powell's opinion for the Court pointed out that, in 1895, this Court considered and conclusively rejected the practice, accepted in several jurisdictions, of requiring the defendant to negate the presumption that he acted with malice aforethought. 421 U.S., at 694-696, 95 S.Ct. 1881. Davis v. United States, 160 U.S. 469, 16 S.Ct. 353, 40 L.Ed. 499 (1895), the decision referred to, held in the context of a federal murder prosecution that the prosecution must shoulder the burden of proving the accused was sane at the time of the commission of the crime. This was so, the Court concluded, because "the crime of murder necessarily involves the possession by the accused of such mental capacity as will render him criminally responsible for his acts." Id., at 485, 16 S.Ct. 353. It is thus clear, following Davis, at least in the context of federal criminal procedure, that the accused's sanity is an ingredient of mens rea, an element of the crime which the prosecution must prove beyond a reasonable doubt.


10
Leland v. Oregon presented the same question in the context of a state rule requiring an accused to prove his insanity beyond a reasonable doubt. Leland refused to extend the holding of Davis to the States based on reluctance "to interfere with Oregon's determination of its policy with respect to the burden of proof on the issue of insanity since we cannot say that policy violates generally accepted concepts of basic standards of justice." Id., at 799, 72 S.Ct. 1002. In effect, the Court concluded that Davis was not a constitutional holding, but rather prescribed a policy necessary to achieve uniformity in federal prosecutions. Id., at 797-798, 72 S.Ct. 1002.


11
My Brother Rehnquist's separate concurring opinion in Mullaney, in which The Chief Justice joined, would distinguish Leland on the basis that the issue of sanity as a defense to a criminal charge is considered by the jury only after it has found that all elements of the offense, including mens rea, are proved beyond a reasonable doubt. Although that opinion concedes that "evidence relevant to insanity as defined by state law may also be relevant to whether the required mens rea was present, (it states that) the existence or nonexistence of legal insanity bears no necessary relationship to the existence or nonexistence of the required mental elements of the crime." 421 U.S., at 705-706, 95 S.Ct. 1881.


12
I do not think that the logic of this view is self-evident. Like the state rule invalidated in Mullaney, which implied malice unless the accused negated it, the plea of insanity, whether or not the State chooses to characterize it as an affirmative defense, relates to the accused's state of mind, an essential element of the crime, and bears upon the appropriate form of punishment. Nor is it sufficient after Mullaney to say, as the Court did in Leland, that a State may characterize the insanity defense as it chooses. We said in Mullaney that the requirement of Winship that the State prove all elements of the crime was one of substance, not limited to "a State's definition of the elements of the crime . . . ." 421 U.S. 699 n. 24, 95 S.Ct. 1881.


13
The Court's summary disposition of this case is especially inappropriate since Hicks v. Miranda, 422 U.S. 332, 95 S.Ct. 2281, 45 L.Ed.2d 223 (1975) accords that disposition precedential weight. See also Colorado Springs Amusements, Ltd. v. Rizzo, 428 U.S. 913, 96 S.Ct. 3228, 49 L.Ed.2d 1221 (1976) (Brennan, J., dissenting). Given the transparent erosion of Leland by Winship and Mullaney, the question whether Leland has continuing validity surely merits full briefing and oral argument.
