Morissette v. United States/Opinion of the Court

This would have remained a profoundly insignificant case to all except its immediate parties had it not been so tried and submitted to the jury as to raise questions both fundamental and far-reaching in federal criminal law, for which reason we granted certiorari.

On a large tract of uninhabited and untilled land in a wooded and sparsely populated area of Michigan, the Government established a practice bombing range over which the Air Force dropped simulated bombs at ground targets. These bombs consisted of a metal cylinder about forty inches long and eight inches across, filled with sand and enough black powder to cause a smoke puff by which the strike could be located. At various places about the range signs read 'Danger-Keep Out-Bombing Range.' Nevertheless, the range was known as good deer country and was extensively hunted.

Spent bomb casings were cleared from the targets and thrown into piles 'so that they will be out of the way.' They were not sacked or piled in any order but were dumped in heaps, some of which had been accumulating for four years or upwards, were exposed to the weather and rusting away.

Morissette, in December of 1948, went hunting in this area but did not get a deer. He thought to meet expenses of the trip by salvaging some of these casings. He loaded three tons of them on his truck and took them to a nearby farm, where they were flattened by driving a tractor over them. After expending this labor and trucking them to market in Flint, he realized $84.

Morissette, by occupation, is a fruit stand operator in summer and a trucker and scrap iron collector in winter. An honorably discharged veteran of World War II, he enjoys a good name among his neighbors and has had no blemish on his record more disreputable than a conviction for reckless driving.

The loading, crushing and transporting of these casings were all in broad daylight, in full view of passers-by, without the slightest effort at concealment. When an investigation was started, Morissette voluntarily, promptly and candidly told the whole story to the authorities, saying that he had no intention of stealing but thought the property was abandoned, unwanted and considered of no value to the Government. He was indicted, however, on the charge that he 'did unlawfully, wilfully and knowingly steal and convert' property of the United States of the value of $84, in violation of 18 U.S.C. § 641, 18 U.S.C.A. § 641, which provides that 'whoever embezzles, steals, purloins, or knowingly converts' government property is punishable by fine and imprisonment. Morissette was convicted and sentenced to imprisonment for two months or to pay a fine of $200. The Court of Appeals affirmed, one judge dissenting.

On his trial, Morissette, as he had at all times told investigating officers, testified that from appearances he believed the casings were cast-off and abandoned, that he did not intend to steal the property, and took it with no wrongful or criminal intent. The trial court, however, was unimpressed, and ruled: '(H)e took it because he thought it was abandoned and he knew he was on government property. * *  * That is no defense. * *  * I don't think anybody can have the defense they thought the property was abandoned on another man's piece of property.' The court stated: 'I will not permit you to show this man thought it was abandoned. * *  * I hold in this case that there is no question of abandoned property.' The court refused to submit or to allow counsel to argue to the jury whether Morissette acted with innocent intention. It charged: 'And I instruct you that if you believe the testimony of the government in this case, he intended to take it. * *  * He had no right to take this property. * *  * (A)nd it is no defense to claim that it was abandoned, because it was on private property. * *  * And I instruct you to this effect: That if this young man took this property (and he says he did), without any permission (he says he did), that was on the property of the United States Government (he says it was), that it was of the value of one cent or more (and evidently it was), that he is guilty of the offense charged here. If you believe the government, he is guilty. * *  * The question on intent is whether or not he intended to take the property. He says he did. Therefore, if you believe either side, he is guilty.' Petitioner's counsel contended, 'But the taking must have been with a felonious intent.' The court ruled, however: 'That is presumed by his own act.'

The Court of Appeals suggested that 'greater restraint in expression should have been exercised', but affirmed the conviction because, 'As we have interpreted the statute, appellant was guilty of its violation beyond a shadow of doubt, as evidenced even by his own admissions.' Its construction of the statute is that it creates several separate and distinct offenses, one being knowing conversion of government property. The court ruled that this particular offense requires no element of criminal intent. This conclusion was thought to be required by the failure of Congress to express such a requisite and this Court's decisions in United States v. Behrman, 258 U.S. 280, 42 S.Ct. 303, 66 L.Ed. 619, and United States v. Balint, 258 U.S. 250, 42 S.Ct. 301, 66 L.Ed. 604.

In those cases this Court did construe mere omission from a criminal enactment of any mention of criminal intent as dispensing with it. If they be deemed precedents for principles of construction generally applicable to federal penal statutes, they authorize this conviction. Indeed, such adoption of the literal reasoning announced in those cases would do this and more-it would sweep out of all federal crimes, except when expressly preserved, the ancient requirement of a culpable state of mind. We think a re sume of their historical background is convincing that an effect has been ascribed to them more comprehensive than was contemplated and one inconsistent with our philosophy of criminal law.

The contention that an injury can amount to a crime only when inflicted by intention is no provincial or transient notion. It is as universal and persistent in mature systems of law as belief in freedom of the human will and a consequent ability and duty of the normal individual to choose between good and evil. A relation between some mental element and punishment for a harmful act is almost as instinctive as the child's familiar exculpatory 'But I didn't mean to,' and has afforded the rational basis for a tardy and unfinished substitution of deterrence and reformation in place of retaliation and vengeance as the motivation for public prosecution. Unqualified acceptance of this doctrine by English common law in the Eighteenth Century was indicated by Blackstone's sweeping statement that to constitute any crime there must first be a 'vicious will.' Common-law commentators of the Nineteenth Century early pronounced the same principle, although a few exceptions not relevant to our present problem came to be recognized.

Crime, as a compound concept, generally constituted only from concurrence of an evil-meaning mind with an evil-doing hand, was congenial to an intense individualism and took deep and early root in American soil. As the state codified the common law of crimes, even if their enactments were silent on the subject, their courts assumed that the omission did not signify disapproval of the principle but merely recognized that intent was so inherent in the idea of the offense that it required no statutory affirmation. Courts, with little hesitation or division, found an implication of the requirement as to offenses that were taken over from the common law. The unanimity with which they have adhered to the central thought that wrongdoing must be conscious to be criminal is emphasized by the variety, disparity and confusion of their definitions of the requisite but elusive mental element. However, courts of various jurisdictions, and for the purposes of different offenses, have devised working formulae, if not scientific ones, for the instruction of juries around such terms as 'felonious intent,' 'criminal intent,' 'malice aforethought,' 'guilty knowledge,' 'fraudulent intent,' 'wilfulness,' 'scienter,' to denote guilty knowledge, or 'mens rea,' to signify an evil purpose or mental culpability. By use or combination of these various tokens, they have sought to protect those who were not blameworthy in mind from conviction of infamous common-law crimes.

However, the Balint and Behrman offenses belong to a category of another character, with very different antecedents and origins. The crimes there involved depend on no mental element but consist only of forbidden acts or omissions. This, while not expressed by the Court, is made clear from examination of a century-old but accelerating tendency, discernible both here and in England, to call into existence new duties and crimes which disregard any ingredient of intent. The industrial revolution multiplied the number of workmen exposed to injury from increasingly powerful and complex mechanisms, driven by freshly discovered sources of energy, requiring higher precautions by employers. Traffic of velocities, volumes and varieties unheard of came to subject the wayfarer to intolerable casualty risks if owners and drivers were not to observe new cares and uniformities of conduct. Congestion of cities and crowding of quarters called for health and welfare regulations undreamed of in simpler times. Wide distribution of goods became an instrument of wide distribution of harm when those who dispersed food, drink, drugs, and even securities, did not comply with reasonable standards of quality, integrity, disclosure and care. Such dangers have engendered increasingly numerous and detailed regulations which heighten the duties of those in control of particular industries, trades, properties or activities that affect public health, safety or welfare.

While many of these duties are sanctioned by a more strict civil liability, lawmakers, whether wisely or not, have sought to make such regulations more effective by invoking criminal sanctions to be applied by the familiar technique of criminal prosecutions and convictions. This has confronted the courts with a multitude of prosecutions, based on statutes or administrative regulations, for what have been aptly called 'public welfare offenses.' These cases do not fit neatly into any of such accepted classifications of common-law offenses, such as those against the state, the person, property, or public morals. Many of these offenses are not in the nature of positive aggressions or invasions, with which the common law so often dealt, but are in the nature of neglect where the law requires care, or inaction where it imposes a duty. Many violations of such regulations result in no direct or immediate injury to person or property but merely create the danger or probability of it which the law seeks to minimize. While such offenses do not threaten the security of the state in the manner of treason, they may be regarded as offenses against its authority, for their occurrence impairs the efficiency of controls deemed essential to the social order as presently constituted. In this respect, whatever the intent of the violator, the injury is the same, and the consequences are injurious or not according to fortuity. Hence, legislation applicable to such offenses, as a matter of policy, does not specify intent as a necessary element. The accused, if he does not will the violation, usually is in a position to prevent it with no more care than society might reasonably expect and no more exertion than it might reasonably exact from one who assumed his responsibilities. Also, penalties commonly are relatively small, and conviction does not grave damage to an offender's reputation. Under such considerations, courts have turned to construing statutes and regulations which make no mention of intent as dispensing with it and holding that the guilty act alone makes out the crime. This has not, however, been without expressions of misgiving.

The pilot of the movement in this country appears to be a holding that a tavernkeeper could be convicted for selling liquor to an habitual drunkard even if he did not know the buyer to be such. Barnes v. State, 1849, 19 Conn. 398. Later came Massachusetts holdings that convictions for selling adulterated milk in violation of statutes forbidding such sales require no allegation or proof that defendant knew of the adulteration. Commonwealth v. Farren, 1864, 9 Allen 489; Commonwealth v. Nichols, 1865, 10 Allen 199; Commonwealth v. Waite, 1865, 11 Allen 264. Departures from the common-law tradition, mainly of these general classes, were reviewed and their rationale appraised by Chief Justice Cooley, as follows: 'I agree that as a rule there can be no crime without a criminal intent, but this is not by any means a universal rule. * *  * Many statutes which are in the nature of police regulations, as this is, impose criminal penalties irrespective of any intent to violate them, the purpose being to require a degree of diligence for the protection of the public which shall render violation impossible.' People v. Roby, 1884, 52 Mich. 577, 579, 18 N.W. 365, 366.

After the turn of the Century, a new use for crimes without intent appeared when New York enacted numerous and novel regulations of tenement houses, sanctioned by money penalties. Landlords contended that a guilty intent was essential to establish a violation. Judge Cardozo wrote the answer: 'The defendant asks us to test the meaning of this statute by standards applicable to statutes that govern infamous crimes. The analogy, however, is deceptive. The element of conscious wrongdoing, the guilty mind accompanying the guilty act, is associated with the concept of crimes that are punished as infamous. * *  * Even there it is not an invariable element. * *  * But in the prosecution of minor offenses there is a wider range of practice and of power. Prosecutions for petty penalties have always constituted in our law a class by themselves. * *  * That is true, though the prosecution is criminal in form.' Tenement House Department of City of New York v. McDevitt, 1915, 215 N.Y. 160, 168, 109 N.E. 88, 90.

Soon, employers advanced the same contention as to violations of regulations prescribed by a new labor law. Judge Cardozo, again for the court, pointed out, as a basis for penalizing violations whether intentional or not, that they were punishable only by fine 'moderate in amount', but cautiously added that in sustaining the power so to fine unintended violations 'we are not to be understood as sustaining to a like length the power to imprison. We leave that question open.' People ex rel. Price v. Sheffield Farms-Slawson-Decker Co., 1918, 225 N.Y. 25, 32-33, 121 N.E. 474, 476, 477.

Thus, for diverse but reconcilable reasons, state courts converged on the same result, discontinuing inquiry into intent in a limited class of offenses against such statutory regulations.

Before long, similar questions growing out of federal legislation reached this Court. Its judgments were in harmony with this consensus of state judicial opinion, the existence of which may have led the Court to overlook the need for full exposition of their rationale in the context of federal law. In overruling a contention that there can be no conviction on an indictment which makes no charge of criminal intent but alleges only making of a sale of a narcotic forbidden by law, Chief Justice Taft, wrote: 'While the general rule at common law was that the scienter was a necessary element in the indictment and proof of every crime, and this was followed in regard to statutory crimes even where the statutory definition did not in terms include it * *  *, there has been a modification of this view in respect to prosecutions under statutes the purpose of which would be obstructed by such a requirement. It is a question of legislative intent to be construed by the court. * *  * ' United States v. Balint, supra, 258 U.S. 251-252, 42 S.Ct. 302.

He referred, however, to 'regulatory measures in the exercise of what is called the police power where the emphasis of the statute is evidently upon achievement of some social betterment rather than the punishment of the crimes as in cases of mala in se,' and drew his citation of supporting authority chiefly from state court cases dealing with regulatory offenses. Id., 258 U.S. at page 252, 42 S.Ct. at page 302.

On the same day, the Court determined that an offense under the Narcotic Drug Act does not require intent, saying, 'If the offense be a statutory one, and intent or knowledge is not made an element of it, the indictment need not charge such knowledge or intent.' United States v. Behrman, supra, 258 U.S. at page 288, 42 S.Ct. at page 304.

Of course, the purpose of every statute would be 'obstructed' by requiring a finding of intent, if we assume that it had a purpose to convict without it. Therefore, the obstruction rationale does not help us to learn the purpose of the omission by Congress. And since no federal crime can exist except by force of statute, the reasoning of the Behrman opinion, if read literally, would work far-reaching changes in the composition of all federal crimes. Had such a result been contemplated, it could hardly have escaped mention by a Court which numbered among its members one especially interested and informed concerning the importance of intent in common-law crimes. This might be the more expected since the Behrman holding did call forth his dissent, in which Mr. Justice McReynolds and Mr. Justice Brandeis joined, omitting any such mention.

It was not until recently that the Court took occasion more explicitly to relate abandonment of the ingredient of intent, not merely with considerations of expediency in obtaining convictions, nor with the malum prohibitum classification of the crime, but with the peculiar nature and quality of the offense. We referred to ' * *  * a now familiar type of legislation whereby penalties serve as effective means of regulation', and continued, 'such legislation dispenses with the conventional requirement for criminal conduct awareness of some wrongdoing. In the interest of the larger good it puts the burden of acting at hazard upon a person otherwise innocent but standing in responsible relation to a public danger.' But we warned: 'Hardship there doubtless may be under a statute which thus penalizes the transaction though consciousness of wrongdoing be totally wanting.' United States v. Dotter-weich, 320 U.S. 277, 280-281, 284, 64 S.Ct. 134, 136, 88 L.Ed. 48.

Neither this Court nor, so far as we are aware, any other has undertaken to delineate a precise line or set forth comprehensive criteria for distinguishing between crimes that require a mental element and crimes that do not. We attempt no closed definition, for the law on the subject is neither settled nor static. The conclusion reached in the Balint and Behrman cases has our approval and adherence for the circumstances to which it was there applied. A quite different question here is whether we will expand the doctrine of crimes without intent to include those charged here.

Stealing, larceny, and its variants and equivalents, were among the earliest offenses known to the law that existed before legislation; they are invasions of rights of property which stir a sense of insecurity in the whole community and arouse public demand for retribution, the penalty is high and, when a sufficient amount is involved, the infamy is that of a felony, which, says Maitland, is ' * *  * as bad a word as you can give to man or thing.' State courts of last resort, on whom fall the heaviest burden of interpreting criminal law in this country, have consistently retained the requirement of intent in larceny-type offenses. If any state has deviated, the exception has neither been called to our attention nor disclosed by our research.

Congress, therefore, omitted any express prescription of criminal intent from the enactment before us in the light of an unbroken course of judicial decision in all constituent states of the Union holding intent inherent in this class of offense, even when not expressed in a statute. Congressional silence as to mental elements in an Act merely adopting into federal statutory law a concept of crime already so well defined in common law and statutory interpretation by the states may warrant quite contrary inferences than the same silence in creating an offense new to general law, for whose definition the courts have no guidance except the Act. Because the offenses before this Court in the Balint and Behrman cases were of this latter class, we cannot accept them as authority for eliminating intent from offenses incorporated from the common law. Nor do exhaustive studies of state court cases disclose any well-considered decisions applying the doctrine of crime without intent to such enacted common-law offenses, although a few deviations are notable as illustrative of the danger inherent in the Government's contentions here.

The Government asks us by a feat of construction radically to change the weights and balances in the scales of justice. The purpose and obvious effect of doing away with the requirement of a guilty intent is to ease the prosecution's path to conviction, to strip the defendant of such benefit as he derived at common law from innocence of evil purpose, and to circumscribe the freedom heretofore allowed juries. Such a manifest impairment of the immunities of the individual should not be extended to common-law crimes on judicial initiative.

The spirit of the doctrine which denies to the federal judiciary power to create crimes forthrightly admonishes that we should not enlarge the reach of enacted crimes by constituting them from anything less than the incriminating components contemplated by the words used in the statute. And where Congress borrows terms of art in which are accumulated the legal tradition and meaning of centuries of practice, it presumably knows and adopts the cluster of ideas that were attached to each borrowed word in the body of learning from which it was taken and the meaning its use will convey to the judicial mind unless otherwise instructed. In such case, absence of contrary direction may be taken as satisfaction with widely accepted definitions, not as a departure from them.

We hold that mere omission from § 641 of any mention of intent will not be construed as eliminating that element from the crimes denounced.

It is suggested, however, that the history and purposes of § 641 imply something more affirmative as to elimination of intent from at least one of the offenses charged under it in this case. The argument does not contest that criminal intent is retained in the offenses of embezzlement, stealing and purloining, as incorporated into this section. But it is urged that Congress joined with those, as a new, separate and distinct offense, knowingly to convert government property, under circumstances which imply that it is an offense in which the mental element of intent is not necessary.

Congress has been alert to what often is a decisive function of some mental element in crime. It has seen fit to prescribe that an evil state of mind, described variously in one or more such terms as 'intentional,' 'wilful,' 'knowing,' 'fraudulent' or 'malicious,' will make criminal an otherwise indifferent act, or increase the degree of the offense or its punishment. Also, it has at times required a specific intent or purpose which will require some specialized knowledge or design for some evil beyond the common-law intent to do injury. The law under some circumstances recognizes good faith or blameless intent as a defense, partial defense, or as an element to be considered in mitigation of punishment. And treason-the one crime deemed grave enough for definition in our Constitution itself-requires not only the duly witnessed overt act of aid and comfort to the enemy but also the mental element of disloyalty or adherence to the enemy. In view of the care that has been bestowed upon the subject, it is significant that we have not found, nor has our attention been directed to, any instance in which Congress has expressly eliminated the mental element from a crime taken over from the common law.

The section with which we are here concerned was enacted in 1948, as a consolidation of four former sections of Title 18, as adopted in 1940, which in turn were derived from two sections of the Revised Statutes. The pertinent legislative and judicial history of these antecedents, as well as of § 641, is footnoted. We find no other purpose in the 1948 re-enactment than to collect from scattered sources crimes so kindred as to belong in one category. Not one of these had been interpreted to be a crime without intention and no purpose to differentiate between them in the matter of intent is disclosed. No inference that some were and some were not crimes of intention can be drawn from any difference in classification or punishment. Not one fits the congressional classification of the petty offense; each is, at its least, a misdemeanor, and if the amount involved is one hundred or more dollars each is a felony. If one crime without intent has been smuggled into a section whose dominant offenses do require intent, it was put in ill-fitting and compromising company. The Government apparently did not believe that conversion stood so alone when it drew this one-count indictmemt to charge that Morissette 'did unlawfully, wilfully and knowingly steal and convert to his own use.'

Congress, by the language of this section, has been at pains to incriminate only 'knowing' conversions. But, at common law, there are unwitting acts which constitute conversions. In the civil tort, except for recovery of exemplary damages, the defendant's knowledge, intent, motive, mistake, and good faith are generally irrelevant. If one takes property which turns out to belong to another, his innocent intent will not shield him from making restitution or indemnity, for his well-meaning may not be allowed to deprive another of his own.

Had the statute applied to conversions without qualification, it would have made crimes of all unwitting, inadvertent and unintended conversions. Knowledge, of course, is not identical with intent and may not have been the most apt words of limitation. But knowing conversion requires more than knowledge that defendant was taking the property into his possession. He must have had knowledge of the facts, though not necessarily the law, that made the taking a conversion. In the case before us, whether the mental element that Congress required be spoken of as knowledge or as intent, would not seem to alter its bearing on guilt. for it is not apparent how Morissette could have knowingly or intentionally converted property that he did not know could be converted, as would be the case if it was in fact abandoned or if he truly believed it to be abandoned and unwanted property.

It is said, and at first blush the claim has plausibility, that, if we construe the statute to require a mental element as part of criminal conversion, it becomes a meaningless duplication of the offense of stealing, and that conversion can be given meaning only by interpreting it to disregard itention. But here again a broader view of the evolution of these crimes throws a different light on the legislation.

It is not surprising if there is considerable overlapping in the embezzlement, stealing, purloining and knowing conversion grouped in this statute. What has concerned codifiers of the larceny-type offense is that gaps or crevices have separated particular crimes of this general class and guilty men have escaped through the breaches. The books contain a surfeit of cases drawing fine distinctions between slightly different circumstances under which one may obtain wrongful advantages from another's property. The codifiers wanted to reach all such instances. Probably every stealing is a conversion, but certainly not every knowing conversion is a stealing. 'To steal means to take away from one in lawful possession without right with the intention to keep wrongfully.' (Italics added.) Irving Trust Co. v. Leff, 253 N.Y. 359, 364, 171 N.E. 569, 571. Conversion, however, may be consummated without any intent to keep and without any wrongful taking, where the initial possession by the converter was entirely lawful. Conversion may include misuse or abuse of property. It may reach use in an unauthorized manner or to an unauthorized extent of property placed in one's custody for limited use. Money rightfully taken into one's custody may be converted without any intent to keep or embezzle it merely by commingling it with the custodian's own, if he was under a duty to keep it separate and intact. It is not difficult to think of intentional and knowing abuses and unauthorized uses of government property that might be knowing conversions but which could not be reached as embezzlement, stealing or purloining. Knowing conversion adds significantly to the range of protection of government property without interpreting it to punish unwitting conversions.

The purpose which we here attribute to Congress parallels that of codifiers of common law in England and in the States and demonstrates that the serious problem in drafting such a statute is to avoid gaps and loopholes between offenses. It is significant that the English and State codifiers have tried to cover the same type of conduct that we are suggesting as the purpose of Congress here, without, however, departing from the common-law tradition that these are crimes of intendment.

We find no grounds for inferring any affirmative instruction from Congress to eliminate intent from any offense with which this defendant was charged.

As we read the record, this case was tried on the theory that even if criminal intent were essential its presence (a) should be decided by the court (b) as a presumption of law, apparently conclusive, (c) predicated upon the isolated act of taking rather than upon all of the circumstances. In each of these respects we believe the trial court was in error.

Where intent of the accused is an ingredient of the crime charged, its existence is a question of fact which must be submitted to the jury. State court authorities cited to the effect that intent is relevant in larcenous crimes are equally emphatic and uniform that it is a jury issue. The settled practice and its reason are well stated by Judge Andrews in People v. Flack, 125 N.Y. 324, 334, 26 N.E. 267, 270, 11 L.R.A. 807: 'It is alike the general rule of law, and the dictate of natural justice, that to constitute guilt there must be not only a wrongful act, but a criminal intention. Under our system, (unless in exceptional cases,) both must be found by the jury to justify a conviction for crime. However clear the proof may be, or however inconstrovertible may seem to the judge to be the inference of a criminal intention, the question of intent can never be ruled as a question of law, but must always be submitted to the jury. Jurors may be perverse, the ends of justice may be defeated by unrighteous verdicts; but so long as the functions of the judge and jury are distinct, the one responding to the law, the other to the facts, neither can invade the province of the other without destroying the significance of trial by court and jury. * *  * '

It follows that the trial court may not withdraw or prejudge the issue by instruction that the law raises a presumption of intent from an act. It often is tempting to cast in terms of a 'presumption' a conclusion which a court thinks probable from given facts. The Supreme Court of Florida, for example, in a larceny case, from selected circumstances which are present in this case, has declared a presumption of exactly opposite effect from the one announced by the trial court here: ' * *  * But where the taking is open and there is no subsequent attempt to conceal the property, and no denial, but an avowal, of the taking, a strong presumption arises that there was no felonious intent, which must be repelled by clear and convincing evidence before a conviction is authorized. * *  * ' Kemp v. State, 146 Fla. 101, 104, 200 So. 368, 369.

We think presumptive intent has no place in this case. A conclusive presumption which testimony could not overthrow would effectively eliminate intent as an ingredient of the offense. A presumption which would permit but not require the jury to assume intent from an isolated fact would prejudge a conclusion which the jury should reach of its own volition. A presumption which would permit the jury to make an assumption which all the evidence considered together does not logically establish would give to a proven fact an artificial and fictional effect. In either case, this presumption would conflict with the overriding presumption of innocence with which the law endows the accused and which extends to every element of the crime. Such incriminating presumptions are not to be improvised by the judiciary. Even congressional power to facilitate convictions by substituting presumptions for proof is not without limit. Tot v. United States, 319 U.S. 463, 63 S.Ct. 1241, 87 L.Ed. 1519.

Moreover, the conclusion supplied by presumption in this instance was one of intent to steal the casings, and it was based on the mere fact that defendant took them. The court thought the only question was, 'Did he intend to take the property?' That the removal of them was a conscious and intentional act was admitted. But that isolated fact is not an adequate basis on which the jury should find the criminal intent to steal or knowingly convert, that is, wrongfully to deprive another of possession of property. Whether that intent existed, the jury must determine, nor only from the act of taking, but from that together with defendant's testimony and all of the surrounding circumstances.

Of course, the jury, considering Morissette's awareness that these casings were on government property, his failure to seek any permission for their removal and his self-interest as a witness, might have disbelieved his profession of innocent intent and concluded that his assertion of a belief that the casings were abandoned was an afterthought. Had the jury convicted on proper instructions it would be the end of the matter. But juries are not bound by what seems inescapable logic to judges. They might have concluded that the heaps of spent casings left in the hinterland to rust away presented an appearance of unwanted and abandoned junk, and that lack of any conscious deprivation of property or intentional injury was indicated by Morissette's good character, the openness of the taking, crushing and transporting of the casings, and the candor with which it was all admitted. They might have refused to brand Morissette as a thief. Had they done so, that too would have been the end of the matter.

Reversed.
