Michelson v. United States/Opinion of the Court

by Robert H. Jackson

United States Supreme Court

335 U.S. 469

Michelson  v.  United States

 Argued: Oct. 14, 15, 1948. --- Decided: Dec 20, 1948

In 1947 petitioner Michelson was convicted of bribing a federal revenue agent. ^[1] The Government proved a large payment by accused to the agent for the purpose of influencing his official action. The defendant, as a witness on his own behalf, admitted passing the money but claimed it was done in response to the agent's demands, threats, solicitations, and inducements that amounted to entrapment. It is enough for our purposes to say that determination of the issue turned on whether the jury should believe the agent or the accused. ^[2]

On direct examination of defendant, his own counsel brought out that, in 1927, he had been convicted of a misdemeanor having to do with trading in counterfeit watch dials. On cross-examination it appeared that in 1930, in executing an application for a license to deal in second-hand jewelry, he answered 'No' to the question whether he had theretofore been arrested or summoned for any offense.

Defendant called five witnesses to prove that he enjoyed a good reputation. Two of them testified that their acquaintance with him extended over a period of about thirty years and the others said they had known him at least half that long. A typical examination in chief was as follows:

'Q. Do you know the defendant Michelson? A. Yes.

'Q. How long do you know Mr. Michelson? A. About 30 years.

'Q. Do you know other people who know him? A. Yes.

'Q. Have you have occasion to discuss his reputation for honesty 'Q. You have talked to others? A. Yes.

'Q. And what is his reputation? A. Very good.'

These are representative of answers by three witnesses; two others replied, in substance, that they never had heard anything against Michelson.

On cross-examination, four of the witnesses were asked, in substance, this question: 'Did you ever hear that Mr. Michelson on March 4, 1927, was convicted of a violation of the trademark law in New York City in regard to watches?' This referred to the twenty-year-old conviction about which defendant himself had testified on direct examination. Two of them had heard of it and two had not.

To four of these witnesses the prosecution also addressed the question the allowance of which, over defendant's objection, is claimed to be reversible error:

'Did you ever hear that on October 11th, 1920, the defendant, Solomon Michelson, was arrested for receiving stolen goods?'

None of the witnesses appears to have heard of this.

The trial court asked counsel for the prosecution, out of presence of the jury, 'Is it a fact according to the best information in your possession that Michelson was arrested for receiving stolen goods?' Counsel replied that it was, and to support his good faith exhibited a paper record which defendant's counsel did not challenge.

The judge also on three occasions warned the jury, in terms that are not criticized, of the limited purpose for which this evidence was received. ^[3]

Defendant-petitioner challenges the right of the prosecution so to cross-examine his character witnesses. The Court of Appeals held that it was permissible. The opinion, however, points out that the practice has been severely criticized and invites us, in one respect, to change the rule. ^[4] Serious and responsible criticism has been aimed, however, not alone at the detail now questioned by the Court of Appeals but at common-law doctrine on the whole subject of proof of reputation or character. ^[5] It would not be possible to appraise the usefulness and propriety of this cross-examination without consideration of the unique practice concerning character testimony, of which such cross-examination is a minor part. ^[6]

Courts that follow the common-law tradition almost unanimously have come to disallow resort by the prosecution to any kind of evidence of a defendant's evil character to establish a probability of his guilt. ^[7] Not that the law invests the defendant with a presumption of good character, Greer v. United States, 245 U.S. 559, 38 S.Ct. 209, 62 L.Ed. 469, but it simply closes the whole matter of character, disp sition and reputation on the prosecution's case-in-chief. The State may not show defendant's prior trouble with the law, specific criminal acts, or ill name among his neighbors, even though such facts might logically be persuasive that he is by propensity a probable perpetrator of the crime. ^[8] The inquiry is not rejected because character is irrelevant; ^[9] on the contrary, it is said to weigh too much with the jury and to so overpersuade them as to prejudge one with a bad general record and deny him a fair opportunity to defend against a particular charge. The overriding policy of excluding such evidence, despite its admitted probative value, is the practical experience that its disallowance tends to prevent confusion of issues, unfair surprise and undue prejudice. ^[10]

But this line of inquiry firmly denied to the State is opened to the defendant because character is relevant in resolving probabilities of guilt. ^[11] He may introduce affirmative testimony that the general estimate of his character is so favorable that the jury may infer that he would not be likely to commit the offense charged. This privilege is sometimes valuable to a defendant for this Court has held that such testimony alone, in some circumstances, may be enough to raise a reasonable doubt of guilt and that in the federal courts a jury in a proper case should be so instructed. Edgington v. United States, 164 U.S. 361, 17 S.Ct. 72, 41 L.Ed. 467.

When the defendant elects to initiate a character inquiry, another anomalous rule comes into play. Not only is he permitted to call witnesses to testify from hearsay, but indeed such a witness is not allowed to base his testimony on anything but hearsay. ^[12] What commonly is called 'character evidence' is only such when 'character' is employed as a synonym for 'reputation.' The witness may not testify about defendant's specific acts or courses of conduct or his possession of a particular disposition or of benign mental and moral traits; nor can he testify that his own acquaintance, observation, and knowledge of defendant leads to his own independent opinion that defendant possesses a good general or specific character, inconsistent with commission f acts charged. The witness is, however, allowed to summarize what he has heard in the community, although much of it may have been said by persons less qualified to judge than himself. The evidence which the law permits is not as to the personality of defendant but only as to the shadow his daily life has cast in his neighborhood. This has been well described in a different connection as 'the slow growth of months and years, the resultant picture of forgotten incidents, passing events, habitual and daily conduct, presumably honest because disinterested, and safer to be trusted because prone to suspect. * * * It is for that reason that such general repute is permitted to be proven. It sums up a multitude of trivial details. It compacts into the brief phrase of a verdict the teaching of many incidents and the conduct of years. It is the average intelligence drawing its conclusion.' Finch J., in Badger v. Badger, 88 N.Y. 546, 552, 42 Am.Rep. 263.

While courts have recognized logical grounds for criticism of this type of opinion-based-on-hearsay testimony, it is said to be justified by 'overwhelming considerations of practical convenience' in avoiding innumerable collateral issues which, if it were attempted to prove character by direct testimony, would complicate and confuse the trial, distract the minds of jurymen and befog the chief issues in the litigation. People v. Van Gaasbeck, 189 N.Y. 408, 418, 82 N.E. 718, 22 L.R.A.,N.S., 650, 12 Ann.Cas. 745.

Another paradox in this branch of the law of evidence is that the delicate and responsible task of compacting reputation hearsay into the 'brief phrase of a verdict' is one of the few instances in which conclusions are accepted from a witness on a subject in which he is not an expert. However, the witness must qualify to give an opinion by showing such acquaintance with the defendant, the community in which he has lived and the circles in which he has moved, as to speak with authority of the terms in which generally he is regarded. To require affirmative knowledge of the reputation may seem inconsistent with the latitude given to the witness to testify when all he can say of the reputation is that he has 'heard nothing against defendant.' This is permitted upon assumption that, if no ill is reported of one, his reputation must be good. ^[13] But this answer is accepted only from a witness whose knowledge of defendant's habitat and surroundings is intimate enough so that his failure to hear of any relevant ill repute is an assurance that no ugly rumors were about. ^[14]

Thus the law extends helpful but illogical options to a defendant. Experience taught a necessity that they be counterweighted with equally illogical conditions to keep the advantage from becoming an unfair and unreasonable one. The price a defendant must pay for attempting to prove his good name is to throw open the entire subject which the law has kept closed for his benefit and to make himself vulnerable where the law otherwise shields him. The prosecution may pursue the inquiry with contradictory witnesses ^[15] to show that damaging rumors, whether or not well-grounded, were afloat-for it is not the man that he is, but the name that he has which is put in issue. Another hazard is that his own witness is subject to cross-examination as to the contents and extent of the hears y on which he bases his conclusions, and he may be required to disclose rumors and reports that are current even if they do not affect his own conclusion. ^[16] It may test the sufficiency of his knowledge by asking what stories were circulating concerning events, such as one's arrest, about which people normally comment and speculate. Thus, while the law gives defendant the option to show as a fact that his reputation reflects a life and habit incompatible with commission of the offense charged, it subjects his proof to tests of credibility designed to prevent him from profiting by a mere parade of partisans.

To thus digress from evidence as to the offense to hear a contest as to the standing of the accused, at its best oopens a tricky line of inquiry as to a shapeless and elusive subject matter. At its worst it opens a veritable Pandora's box of irresponsible gossip, innuendo and smear. In the frontier phase of our law's development, calling friends to vouch for defendant's good character, and its counterpart-calling the rivals and enemies of a witness to impeach him by testifying that his reputation for veracity was so bad that he was unworthy of belief on his oath were favorite and frequent ways of converting an individual litigation into a community contest and a trial into a spectacle. Growth of urban conditions, where one may never know or hear the name of his next-door neighbor, have tended to limit the use of these techniques and to deprive them of weight with juries. The popularity of both procedures has subsided, but courts of last resort have sought to overcome danger that the true issues will be obscured and confused by investing the trial court with discretion to limit the number of such witnesses and to control cross-examination. Both propriety and abuse of hearsay reputation testimony, on both sides, depend on numerous and subtle considerations, difficult to detect or appraise from a cold record, and therefore rarely and only on clear showing of prejudicial abuse of discretion will Courts of Appeals disturb rulings of trial courts on this subject. ^[17]

Wide discretion is accompanied by heavy responsibility on trial courts to protect the practice from any misuse. The trial judge was scrupulous to so guard it in the case be ore us. He took pains to ascertain, out of presence of the jury, that the target of the question was an actual event, which would probably result in some comment among acquaintances if not injury to defendant's reputation. He satisfied himself that counsel was not merely taking a random shot at a reputation imprudently exposed or asking a groundless question to waft an unwarranted innuendo into the jury box. ^[18]

The question permitted by the trial court, however, involves several features that may be worthy of comment. Its form invited hearsay; it asked about an arrest, not a conviction, and for an offense not closely similar to the one on trial; and it concerned an occurrence many years past.

Since the whole inquiry, as we have pointed out, is calculated to ascertain the general talk of people about defendant, rather than the witness' own knowledge of him, the form of inquiry, 'Have you heard?' has general approval, and 'Do you know?' is not allowed. ^[19]

A character witness may be cross-examined as to an arrest whether or not it culminated in a conviction, according to the overwhelming weight of authority. ^[20] This rule is sometimes confused with that which prohibits cross-examination to credibility by asking a witness whether he himself has been arrested.

Arrest without more does not, in law any more than in reason, impeach the integrity or impair the credibility of a witness. It happens to the innocent as well as the guilty. Only a conviction, therefore, may be inquired about to undermine the trustworthiness of a witness.

Arrest without more may nevertheless impair or cloud one's reputation. False arrest may do that. Even to be acquitted may damage one's good name if the community receives the verdict with a wink and chooses to remember defendant as one who ought to have been convicted. A conviction, on the other hand, may be accepted as a misfortune or an injustice, and even enhance the standing of one who mends his ways and lives it down. Reputation is the net balance of so many debits and credits that the law does not attach the finality to a conviction when the issue is reputation, that is given to it when the issue is the credibility of the convict.

The inquiry as to an arrest is permissible also because the prosecution has a right to test the qualifications of the witness to bespeak the community opinion. If one never heard the speculations and rumors in which even one's friends indulge upon his arrest, the jury may doubt whether he is capable of giving any very reliable conclusions as to his reputation.

In this case the crime inquired about was receiving stolen goods; the trial was for bribery. The Court of Appeals thought this dissimilarity of offenses too great to sustain the inquiry in logic, though conceding that it is authorized by preponderance of authority. It asks us to substitute the Illinois rule which allows inquiry about arrest, but only for very closely similar if not identifical charges, in place of the rule more generally adhered to in this country and in England. ^[21] We think the facts of this case show the proposal to be inexpedient.

The good charcter which the defendant had sought to establish was broader than the crime charged and included the traits of 'honesty and truthfulness' and 'being a law-abiding citizen.' Possession of these characteristics would seem as incompatible with offering a bribe to a revenue agent as with receiving stolen goods. The crimes may be unlike, but both alike proceed from the same defects of character which the witnesses said this defendant was reputed not to exhibit. It is not only by comparison with the crime on trial but by comparison with the reputation asserted that a court may judge whether the prior arrest should be made subject of inquiry. By this test the inquiry was permissible. It was proper cross-examination because reports of his arrest for receiving stolen goods, if admitted, would tend to weaken the assertion that he was known as an honest and law-abiding citizen. The cross-examination may take in as much ground as the testimony it is designed to verify. To hold otherwise would give defendant the benefit of testimony that he was honest and law-abiding in reputation when such might not be the fact; the refutation was founded on voncictions equally persuasive though not for crimes exactly repeated in the present charge.

The inquiry here concerned an arrest twenty-seven years before the trial. Events a generation old are likely to be lived down and dropped from the present thought and talk of the community and to be absent from the knowledge of younger or more recent acquaintances. The court in its discretion may well exclude inquiry about rumors of an event so remote, unless recent misconduct revived them. But two of these witnesses dated their acquaintance with defendant as commencing thirty years before the trial. Defendant, on direct examination, voluntarily called attention to his conviction twenty years before. While the jury might conclude that a matter so old and indecesive as a 1920 arrest would shed little light on the present reputation and hence propensities of the defendant, we cannot say that, in the context of this evidence and in the absence of objection on this specific ground, its admission was an abuse of discretion.

We do not overlook or minimize the consideration that 'the jury almost surely cannot comprehend the Judge's limiting instructions,' which disturbed the Court of Appeals. The refinements of the evidentiary rules on this subject are such that even lawyers and judges, after study and reflection, often are confused, and surely jurors in the hurried and unfamiliar movement of a trial must find them almost unintelligible. However, limiting instructions on this subject are no more difficult to comprehend or apply than those upon va ious other subjects; for example, instructions that admissions of a co-defendant are to be limited to the question of his guilt and are not to be considered as evidence against other defendants, and instructions as to other problems in the trial of conspiracy charges. A defendant in such a case is powerless to prevent his cause from being irretrievably obscured and confused; but, in cases such as the one before us, the law foreclosed this whole confounding line of inquiry, unless defendant thought the net advantage from opening it up would be with him. Given this option, we think defendants in general and this defendant in particular have no valid complaint at the latitude which existing law allows to the prosecution to meet by cross-examination an issue voluntarily tendered by the defense. See Greer v. United States, 245 U.S. 559, 38 S.Ct. 209, 62 L.Ed. 469.

We end, as we began, with the observation that the law regulating the offering and testing of character testimony may merit many criticisms. England, and some states have overhauled the practice by statute. ^[22] But the task of modernizing the longstanding rules on the subject is one of magnitude and difficulty which even those dedicated to law reform do not lightly undertake. ^[23]

The law of evidence of evidence relating to proof of reputation in criminal cases has developed almost entirely at the hands of state courts of last resort, which have such questions frequently before them. This Court, on the other hand, has contributed little to this or to any phase of the law of evidence, for the reason, among others, that it has had extremely rare occasion to decide such issues, as the paucity of citations in this opinion to our own writings attests. It is obvious that a court which can make only infrequent sallies into the field cannot recast the body of case law on this subject in many, many years, even if it were clear what the rules should be.

We concur in the general opinion of courts, textwriters and the profession that much of this law is archaic, paradoxical and full of compromises and compensations by which an irrational advantage to one side is offset by a poorly reasoned counter-privilege to the other. But somehow it has proved a workable even if clumsy system when moderated by discretionary controls in the hands of a wise and strong trial court. To pull one misshapen stone out of the grotesque structure is more likely simply to upset its present balance between adverse interests than to establish a rational edifice.

The present suggestion is that we adopt for all federal courts a new rule as to cross-examination about prior arrest, adhered to by the courts of only one state and rejected elsewhere. ^[24] The confusion and error it would engender would seem too heavy a price to pay for an almost imperceptible logical improvement, if any, in a system which is justified, if at all, by accumulated judicial exp rience rather than abstract logic. ^[25]

Affirmed.

Notes

1. The first count charged petitioner with bribing in violation of 18 U.S.C. § 91, now 18 U.S.C. § 201, 18 U.S.C.A. § 201, and the affirmance of his conviction on this count by the Court of Appeals, 2 Cir., 165 F.2d 732, is the judgment here under review. The second count charged 'offering' the bribe as a violation of the same statute but his conviction on this count was reversed by the Court of Appeals and is not here involved.
2. Details appear in the Court of Appeals opinion, 2 Cir., 165 F.2d 732.
3. In ruling on the objection when the question was first asked, the Court said: '* * * I instruct the jury that what is happening now is this: the defendant has called character witnesses, and the basis for the evidence given by those character witnesses is the reputation of the defendant in the community, and since the defendant tenders the issue of his reputation the prosecution may ask the witness if she has heard of various incidents in his career. I say to you that regardless of her answer you are not to assume that the incidents asked about actually took place. All that is happening is that this witness' standard of opinion of the reputation of the defendant is being tested. Is that clear?'
4. Footnote 8 to that court's opinion reads as follows (165 F.2d 735):
5. A judge of long trial and appellate experience has uttered a warning which, in the opinion of the writer, we might well have heeded in determining whether to grant certiorari here: '* * * evidence of good character is to be used like any other, once it gets before the jury, and the less they are told about the grounds for its admission, or what they shall do with it, the more likely they are to use it sensibly. The subject seems to gather mist which discussion serves only to thicken, and which we can scarcely hope to dissipate by anything further we can add.' L. Hand in Nash v. United States, 2 Cir., 54 F.2d 1006, 1007.

This was not the earlier rule in English common law and is not now the rule in some civil law countries. 1 Wigmore, Evidence (3d ed., § 1940) § 193.
8. This would be subject to some qualification, as when a prior crime is an element of the later offense; for example, at a trial for being an habitual criminal. There are also well-established exceptions where evidence as to other transactions or a course of fraudulent conduct is admitted to establish fraudulent intent as an element of the crime charged. See, e.g., Fall v. United States, 60 App.D.C. 124, 49 F.2d 506, certiorari denied 283 U.S. 867, 51 S.Ct. 657, 75 L.Ed. 1471; Hatem v. United States, 4 Cir., 42 F.2d 40, certiorari denied 282 U.S. 887, 51 S.Ct. 103, 75 L.Ed. 782; Williamson v. United States, 207 U.S. 425, 28 S.Ct. 163, 52 L.Ed. 278; Allis v. United States, 155 U.S. 117, 15 S.Ct. 36, 39 L.Ed. 91; Wood v. United States, 16 Pet. 342, 10 L.Ed. 987.
9. As long ago as 1865, Chief Justice Cockburn said, 'The truth is, this part of our law is an anomaly. Although, logically speaking, it is quite clear that an antecedent bad character would form quite as reasonable a ground for the presumption and probability of guilt as previous good character lays the foundation of innocence, yet you cannot, on the part of the prosecution, go into evidence as to character.'

The law apparently ignores the existence of such human ciphers as Kipling's Tomlinson, of whom no ill is reported but no good can be recalled. They win seats with the righteous for character evidence purposes, however hard their lot in literature.

16. A classic example in the books is a character witness in a trial for murder. She testified she grew up with defendant, knew his reputation for peace and quiet, and that it was good. On cross-examination she was asked if she had heard that the defendant had shot anybody and, if so, how many. She answered, 'Three or four,' and gave the names of two but could not recall the names of the others. She still insisted, however, that he was of 'good character.' The jury seems to have valued her information more highly than her judgment, and on appeal from conviction the cross-examination was held proper. People v. Laudiero, 192 N.Y. 304, 309, 85 N.E. 132. See also People v. Elliott, 163 N.Y. 11, 57 N.E. 103.
17. See, e.g., Mannix v. United States, 4 Cir., 140 F.2d 250. It has been held that the question may not be hypothetical nor assume unproven facts and ask if they would affect the conclusion, Little v. United States, 8 Cir., 93 F.2d 401; Pittman v. United States, 8 Cir., 42 F.2d 793; Filippelli v. United States, 9 Cir., 6 F.2d 121; and that it may not be so asked as to detail evidence or circumstances of a crime of which defendant was accused. People v. Marendi, 213 N.Y. 600, 107 N.E. 1058. It has been held error to use the question to get before the jury a particular derogatory newspaper article. Sloan v. United States, 8 Cir., 31 F.2d 902. The proof has been confined to general reputation and that among a limited group such as fellow employees in a particular building held inadmissible. Williams v. United States, 168 U.S. 382, 18 S.Ct. 92, 42 L.Ed. 509.
18. This procedure was recommended by Wigmore. But analysis of his innovation emphasizes the way in which law on this subject has evolved from pragmatic considerations rather than from theoretical consistency. The relevant information that it is permissible to lay before the jury is talk or conversation about the defendant's being arrested. That is admissible whether or not an actual arrest had taken place; it might even be more significant of repute if his neighbors were ready to arrest him in rumor when the authorities were not in fact. But before this relevant and proper inquiry can be made, counsel must demonstrate privately to the court an irrelevant and possibly unprobable fact-the reality of arrest. From this permissible inquiry about reports of arrest, the jury is pretty certain to infer that defendant had in fact been arrested and to draw its own conclusions as to character from that fact. The Wigmore suggestion thus limits legally relevant inquiries to those based on legally irrelevant facts in order that the legally irrelevant conclusion which the jury probably will draw from the relevant questions will not be based on unsupported or untrue innuendo. It illustrates Judge Hand's suggestion that the system may work best when explained least. Yet, despite its theoretical paradoxes and deficiencies, we approve the procedure as calculated in practice to hold the inquiry within decent bounds.

21. The Supreme Court of Illinois, in considering its own rule which we are urged to adopt, recognized that 'the rule adhered to in this State is not consistent with the great weight of authority in this country and in England.'

For review of English and State legislation, see 1 Wigmore, Evidence (3d ed., 1940) § 194, et seq. The Pennsylvania statute, Act of March 15, 1911, P.L. 20, § 1, discussed by Wigmore has been amended, Act of July 3, 1947, P.L. 1239, § 1, 19 P.S. § 711. The current statute and Pennsylvania practice were considered recently by the Superior Court of that state. Commonwealth v. Hurt, 163 Pa.Super. 232, 60 A.2d 828.
23. The American Law Institute, in promulgating its 'Model Code of Evidence,' includes the comment, 'Character, whenever used in these Rules, means disposition not reputation. It denotes what a person is, not what he is reputed to be. No rules are laid down as to proof of reputation, when reputation is a fact to be proved. When reputation is a material matter, it is proved in the same manner as is any other disputed fact.' Rule 304. The latter sentence may seem an oversimplification in view of the decisions we have reviewed.
24. See note 21.
25. It must not be overlooked that abuse of cross-examination to test credibility carries its own corrective. Authorities on practice caution the bar of the imprudence as well as the unprofessional nature of attacks on witnesses or defendants which are likely to be resented by the jury.
