Fundamental Cases in Criminal Justice


The following case has been heavily edited and abridged.  The idea is to make it more readable.  As such, they should not be relied upon as binding authority.


Williams v. Florida (1970)

399 U.S. 78

 Prior to his trial for robbery in the State of Florida, petitioner filed a "Motion for a Protective Order," seeking to be excused from the requirements of Rule 1.200 of the Florida Rules of Criminal Procedure. That rule requires a defendant, on written demand of the prosecuting attorney, to give notice in advance of trial if the defendant intends to claim an alibi, and to furnish the prosecuting attorney with information as to the place where he claims to have been and with the names and addresses of the alibi witnesses he intends to use. In his motion petitioner openly declared his intent to claim an alibi, but objected to the further disclosure requirements on the ground that the rule "compels the Defendant in a criminal case to be a witness against himself" in violation of his Fifth and Fourteenth Amendment rights. The motion was denied. Petitioner also filed a pretrial motion to impanel a 12-man jury instead of the six-man jury provided by Florida law in all but capital cases. That motion too was denied. Petitioner was convicted as charged and was sentenced to life imprisonment. The District Court of Appeal affirmed, rejecting petitioner's claims that his Fifth and Sixth Amendment rights had been violated. We granted certiorari.

I.

Florida's notice-of-alibi rule is in essence a requirement that a defendant submit to a limited form of pretrial discovery by the State whenever he intends to rely at trial on the defense of alibi. In exchange for the defendant's disclosure of the witnesses he proposes to use to establish that defense, the State in turn is required to notify the defendant of any witnesses it proposes to offer in rebuttal to that defense. Both sides are under a continuing duty promptly to disclose the names and addresses of additional witnesses bearing on the alibi as they become available. The threatened sanction for failure to comply is the exclusion at trial of the defendant's alibi evidence—except for his own testimony—or, in the case of the State, the exclusion of the State's evidence offered in rebuttal of the alibi.

In this case, following the denial of his Motion for a Protective Order, petitioner complied with the alibi rule and gave the State the name and address of one Mary Scotty. Mrs. Scotty was summoned to the office of the State Attorney on the morning of the trial, where she gave pretrial testimony. At the trial itself, Mrs. Scotty, petitioner, and petitioner's wife all testified that the three of them had been in Mrs. Scotty's apartment during the time of the robbery. On two occasions during cross-examination of Mrs. Scotty, the prosecuting attorney confronted her with her earlier deposition in which she had given dates and times that in some respects did not correspond with the dates and times given at trial. Mrs. Scotty adhered to her trial story, insisting that she had been mistaken in her earlier testimony. The State also offered in rebuttal the testimony of one of the officers investigating the robbery who claimed that Mrs. Scotty had asked him for directions on the afternoon in question during the time when she claimed to have been in her apartment with petitioner and his wife.

We need not linger over the suggestion that the discovery permitted the State against petitioner in this case deprived him of "due process" or a "fair trial." Florida law provides for liberal discovery by the defendant against the State, and the notice-of-alibi rule is itself carefully hedged with reciprocal duties requiring state disclosure to the defendant. Given the ease with which an alibi can be fabricated, the State's interest in protecting itself against an eleventh-hour defense is both obvious and legitimate. Reflecting this interest, notice-of-alibi provisions, dating at least from 1927, are now in existence in a substantial number of States. The adversary system of trial is hardly an end in itself; it is not yet a poker game in which players enjoy an absolute right always to conceal their cards until played. We find ample room in that system, at least as far as "due process" is concerned, for the instant Florida rule, which is designed to enhance the search for truth in the criminal trial by insuring both the defendant and the State ample opportunity to investigate certain facts crucial to the determination of guilt or innocence.

Petitioner's major contention is that he was "compelled . . . to be a witness against himself" contrary to the commands of the Fifth and Fourteenth Amendments because the notice-of-alibi rule required him to give the State the name and address of Mrs. Scotty in advance of trial and thus to furnish the State with information useful in convicting him. No pretrial statement of petitioner was introduced at trial; but armed with Mrs. Scotty's name and address and the knowledge that she was to be petitioner's alibi witness, the State was able to take her deposition in advance of trial and to find rebuttal testimony. Also, requiring him to reveal the elements of his defense is claimed to have interfered with his right to wait until after the State had presented its case to decide how to defend against it.

We conclude, however, as has apparently every other court that has considered the issue, that the privilege against self-incrimination is not violated by a requirement that the defendant give notice of an alibi defense and disclose his alibi witnesses.

The defendant in a criminal trial is frequently forced to testify himself and to call other witnesses in an effort to reduce the risk of conviction. When he presents his witnesses, he must reveal their identity and submit them to cross-examination which in itself may prove incriminating or which may furnish the State with leads to incriminating rebuttal evidence. That the defendant faces such a dilemma demanding a choice between complete silence and presenting a defense has never been thought an invasion of the privilege against compelled self-incrimination. The pressures generated by the State's evidence may be severe but they do not vitiate the defendant's choice to present an alibi defense and witnesses to prove it, even though the attempted defense ends in catastrophe for the defendant. However "testimonial" or "incriminating" the alibi defense proves to be, it cannot be considered "compelled" within the meaning of the Fifth and Fourteenth Amendments.

Very similar constraints operate on the defendant when the State requires pretrial notice of alibi and the naming of alibi witnesses. Nothing in such a rule requires the defendant to rely on an alibi or prevents him from abandoning the defense; these matters are left to his unfettered choice. That choice must be made, but the pressures that bear on his pretrial decision are of the same nature as those that would induce him to call alibi witnesses at the trial: the force of historical fact beyond both his and the State's control and the strength of the State's case built on these facts. Response to that kind of pressure by offering evidence or testimony is not compelled self-incrimination transgressing the Fifth and Fourteenth Amendments.

In the case before us, the notice-of-alibi rule by itself in no way affected petitioner's crucial decision to call alibi witnesses or added to the legitimate pressures leading to that course of action. At most, the rule only compelled petitioner to accelerate the timing of his disclosure, forcing him to divulge at an earlier date information that the petitioner from the beginning planned to divulge at trial. Nothing in the Fifth Amendment privilege entitles a defendant as a matter of constitutional right to await the end of the State's case before announcing the nature of his defense, any more than it entitles him to await the jury's verdict on the State's case-in-chief before deciding whether or not to take the stand himself.

Petitioner concedes that absent the notice-of-alibi rule the Constitution would raise no bar to the court's granting the State a continuance at trial on the ground of surprise as soon as the alibi witness is called. Nor would there be self-incrimination problems if, during that continuance, the State was permitted to do precisely what it did here prior to trial: take the deposition of the witness and find rebuttal evidence. But if so utilizing a continuance is permissible under the Fifth and Fourteenth Amendments, then surely the same result may be accomplished through pretrial discovery, as it was here, avoiding the necessity of a disrupted trial. We decline to hold that the privilege against compulsory self-incrimination guarantees the defendant the right to surprise the State with an alibi defense.

II.

In Duncan v. Louisiana, we held that the Fourteenth Amendment guarantees a right to trial by jury in all criminal cases that—were they to be tried in a federal court—would come within the Sixth Amendment's guarantee. Petitioner's trial for robbery on July 3, 1968, clearly falls within the scope of that holding. The question in this case then is whether the constitutional guarantee of a trial by "jury" necessarily requires trial by exactly 12 persons, rather than some lesser number—in this case six. We hold that the 12-man panel is not a necessary ingredient of "trial by jury," and that respondent's refusal to impanel more than the six members provided for by Florida law did not violate petitioner's Sixth Amendment rights as applied to the States through the Fourteenth.

We had occasion in Duncan v. Louisiana, to review briefly the oft-told history of the development of trial by jury in criminal cases. That history revealed a long tradition attaching great importance to the concept of relying on a body of one's peers to determine guilt or innocence as a safeguard against arbitrary law enforcement. That same history, however, affords little insight into the considerations that gradually led the size of that body to be generally fixed at 12. Some have suggested that the number 12 was fixed upon simply because that was the number of the presentment jury from the hundred, from which the petit jury developed. Other, less circular but more fanciful reasons for the number 12 have been given, "but they were all brought forward after the number was fixed," and rest on little more than mystical or superstitious insights into the significance of "12." Lord Coke's explanation that the "number of twelve is much respected in holy writ, as 12 apostles, 12 stones, 12 tribes, etc.," is typical. In short, while sometime in the 14th century the size of the jury at common law came to be fixed generally at 12, that particular feature of the jury system appears to have been a historical accident, unrelated to the great purposes which gave rise to the jury in the first place. The question before us is whether this accidental feature of the jury has been immutably codified into our Constitution.

This Court's earlier decisions have assumed an affirmative answer to this question. The leading case so construing the Sixth Amendment is Thompson v. Utah. There the defendant had been tried and convicted by a 12-man jury for a crime committed in the Territory of Utah. A new trial was granted, but by that time Utah had been admitted as a State. The defendant's new trial proceeded under Utah's Constitution, providing for a jury of only eight members. This Court reversed the resulting conviction, holding that Utah's constitutional provision was an ex post facto law as applied to the defendant. In reaching its conclusion, the Court announced that the Sixth Amendment was applicable to the defendant's trial when Utah was a Territory, and that the jury referred to in the Amendment was a jury "constituted, as it was at common law, of twelve persons, neither more nor less." Arguably unnecessary for the result, this announcement was supported simply by referring to the Magna Carta, and by quoting passages from treatises which noted—what has already been seen—that at common law the jury did indeed consist of 12. Noticeably absent was any discussion of the essential step in the argument: namely, that every feature of the jury as it existed at common law—whether incidental or essential to that institution—was necessarily included in the Constitution wherever that document referred to a "jury." Subsequent decisions have reaffirmed the announcement in Thompson, often in dictum and usually by relying—where there was any discussion of the issue at all—solely on the fact that the common-law jury consisted of 12.

While "the intent of the Framers" is often an elusive quarry, the relevant constitutional history casts considerable doubt on the easy assumption in our past decisions that if a given feature existed in a jury at common law in 1789, then it was necessarily preserved in the Constitution. Provisions for jury trial were first placed in the Constitution in Article III's provision that "the Trial of all Crimes . . . shall be by Jury; and such Trial shall be held in the State where the said Crimes shall have been committed." The "very scanty history [of this provision] in the records of the Constitutional Convention" sheds little light either way on the intended correlation between Article III's "jury" and the features of the jury at common law. Indeed, pending and after the adoption of the Constitution, fears were expressed that Article III's provision failed to preserve the common-law right to be tried by a "jury of the vicinage."

That concern, as well as the concern to preserve the right to jury in civil as well as criminal cases, furnished part of the impetus for introducing amendments to the Constitution that ultimately resulted in the jury trial provisions of the Sixth and Seventh Amendments. As introduced by James Madison in the House, the Amendment relating to jury trial in criminal cases would have provided that:

"The trial of all crimes . . . shall be by an impartial jury of freeholders of the vicinage, with the requisite of unanimity for conviction, of the right of challenge, and other accustomed requisites. . . ."

….

Three significant features may be observed in this sketch of the background of the Constitution's jury trial provisions. First, even though the vicinage requirement was as much a feature of the common-law jury as was the 12-man requirement, the mere reference to "trial by jury" in Article III was not interpreted to include that feature. Indeed, as the subsequent debates over the Amendments indicate, disagreement arose over whether the feature should be included at all in its common-law sense, resulting in the compromise described above. Second, provisions that would have explicitly tied the "jury" concept to the "accustomed requisites" of the time were eliminated. Such action is concededly open to the explanation that the "accustomed requisites" were thought to be already included in the concept of a "jury." But that explanation is no more plausible than the contrary one: that the deletion had some substantive effect. Indeed, given the clear expectation that a substantive change would be effected by the inclusion or deletion of an explicit "vicinage" requirement, the latter explanation is, if anything, the more plausible. Finally, contemporary legislative and constitutional provisions indicate that where Congress wanted to leave no doubt that it was incorporating existing common-law features of the jury system, it knew how to use express language to that effect. … And the Seventh Amendment, providing for jury trial in civil cases, explicitly added that "no fact tried by a jury, shall be otherwise re-examined in any Court of the United States, than according to the rules of the common law."

We do not pretend to be able to divine precisely what the word "jury" imported to the Framers, the First Congress, or the States in 1789. It may well be that the usual expectation was that the jury would consist of 12, and that  hence, the most likely conclusion to be drawn is simply that little thought was actually given to the specific question we face today. But there is absolutely no indication in "the intent of the Framers" of an explicit decision to equate the constitutional and common-law characteristics of the jury. Nothing in this history suggests, then, that we do violence to the letter of the Constitution by turning to other than purely historical considerations to determine which features of the jury system, as it existed at common law, were preserved in the Constitution. The relevant inquiry, as we see it, must be the function that the particular feature performs and its relation to the purposes of the jury trial. Measured by this standard, the 12-man requirement cannot be regarded as an indispensable component of the Sixth Amendment.

The purpose of the jury trial, as we noted in Duncan, is to prevent oppression by the Government. "Providing an accused with the right to be tried by a jury of his peers gave him an inestimable safeguard against the corrupt or overzealous prosecutor and against the compliant, biased, or eccentric judge." Given this purpose, the essential feature of a jury obviously lies in the interposition between the accused and his accuser of the commonsense judgment of a group of laymen, and in the community participation and shared responsibility that results from that group's determination of guilt or innocence. The performance of this role is not a function of the particular number of the body that makes up the jury. To be sure, the number should probably be large enough to promote group deliberation, free from outside attempts at intimidation, and to provide a fair possibility for obtaining a representative cross-section of the community. But we find little reason to think that these goals are in any meaningful sense less likely to be achieved when the jury numbers six, than when it numbers 12—particularly if the requirement of unanimity is retained. And, certainly the reliability of the jury as a factfinder hardly seems likely to be a function of its size.

It might be suggested that the 12-man jury gives a defendant a greater advantage since he has more "chances" of finding a juror who will insist on acquittal and thus prevent conviction. But the advantage might just as easily belong to the State, which also needs only one juror out of twelve insisting on guilt to prevent acquittal. What few experiments have occurred—usually in the civil area—indicate that there is no discernible difference between the results reached by the two different-sized juries. In short, neither currently available evidence nor theory suggests that the 12-man jury is necessarily more advantageous to the defendant than a jury composed of fewer members.

Similarly, while in theory the number of viewpoints represented on a randomly selected jury ought to increase as the size of the jury increases, in practice the difference between the 12-man and the six-man jury in terms of the cross-section of the community represented seems likely to be negligible. Even the 12-man jury cannot insure representation of every distinct voice in the community, particularly given the use of the peremptory challenge. As long as arbitrary exclusions of a particular class from the jury rolls are forbidden, the concern that the cross-section will be significantly diminished if the jury is decreased in size from 12 to six seems an unrealistic one.

We conclude, in short, as we began: the fact that the jury at common law was composed of precisely 12 is a historical accident, unnecessary to effect the purposes of the jury system and wholly without significance "except to mystics." To read the Sixth Amendment as forever codifying a feature so incidental to the real purpose of the Amendment is to ascribe a blind formalism to the Framers which would require considerably more evidence than we have been able to discover in the history and language of the Constitution or in the reasoning of our past decisions. We do not mean to intimate that legislatures can never have good reasons for concluding that the 12-man jury is preferable to the smaller jury, or that such conclusions—reflected in the provisions of most States and in our federal system—are in any sense unwise. Legislatures may well have their own views about the relative value of the larger and smaller juries, and may conclude that, wholly apart from the jury's primary function, it is desirable to spread the collective responsibility for the determination of guilt among the larger group. In capital cases, for example, it appears that no State provides for less than 12 jurors—a fact that suggests implicit recognition of the value of the larger body as a means of legitimating society's decision to impose the death penalty. Our holding does no more than leave these considerations to Congress and the States, unrestrained by an interpretation of the Sixth Amendment that would forever dictate the precise number that can constitute a jury. Consistent with this holding, we conclude that petitioner's Sixth Amendment rights, as applied to the States through the Fourteenth Amendment, were not violated by Florida's decision to provide a six-man rather than a 12-man jury.

The judgment of the Florida District Court of Appeal is Affirmed.
