Innocent Until Proven Guilty:

The Origins of a Legal Maxim


Ken Pennington


The United Nations incorporated the principle that a defendant is innocent until proven guilty in its Declaration of Human Rights in 1948 under article eleven, section one. The maxim also found a place in the European Convention for the Protection of Human Rights in 1953 [as article 6, section 2] and was incorporated into the United Nations International Covenant on Civil and Political Rights [as article 14, section 2]. This was a satisfying step for Americans because there are few maxims that have a greater resonance in Anglo-American, common law jurisprudence. Our respect for the maxim does pose an interesting conundrum: it cannot be found in Magna Carta, the English Bill of Rights of 1689, the Declaration of Independence, or the Constitution of the United States; or, I might add, in the works of the great English jurists, Bracton, Coke, or Blackstone. Nevertheless, some scholars have claimed that the maxim has been firmly embedded in English jurisprudence since earliest times.

Claims about the maxim's Anglo-Saxon roots are sometimes quite stirring and display a particularly British capacity to create intellectual Camelots -- on their side of the Channel. An English scholar named Clementi gave a talk on the maxim at Göttingen, Germany in 1974.(1) He informed his learned, continental audience about the maxim's unique Anglo-Saxon origins. When a fourteenth-century English Parliament declared its complete independence from Roman law, the principle on which Parliament stood, was, he said, "that an accused person must be deemed innocent until such time as his or her guilt has been proved conclusively in court." Clementi declared that he would not have bothered his continental colleagues with "intimate details of English pragmatism" before England had entered the Common Market. Now, however, he assured them that "there is good reason why you should become better acquainted with us." English devotion to the principle of 'Innocent until proven guilty' served to "emphasize a separation between England and its European mainland in matters of law." With missionary zeal, Clementi propounded the virtues of innocence while being guilty of explicating a text in which themaxim was completely absent.

Clementi did not know that the maxim "Innocent until proven guilty" cannot be found in any English court case or any jurisprudential treatise before ca. 1800 --- at least I have not yet found it in one. He also did not seem to know that the French, in spite of their legal system's being based on rebarbative Roman jurisprudence, did include an article in the French Declaration of the Rights of Man and Citizen of 1789 stating that "every man is presumed innocent until declared guilty." These facts raise two questions that will be the subject of this talk: how did this piece of English pragmatism become a part of the Romanist French tradition and how and when did the maxim surface in the Anglo-American tradition?

We can know exactly when the maxim formally entered American law: through a Supreme Court decision of 1894, Coffin vs. U.S. The forty-fourth charge in the case -- "The law presumes that persons charged with crime are innocent until they are proven by competent evidence to be guilty" --- was rejected by the lower court in its instruction to the jury. The appeal was based in part on the lower court's refusal.(2)

Although the court rejected this charge, it did instruct the jury that "Before you can find any one of the defendants guilty you must be satisfied of his guilt as charged in some of the counts of the indictment beyond a reasonable doubt." The lower court then instructed the jury at great length on the doctrine of reasonable doubt and its relationship to evidence. The Supreme Court saw its task as determining whether the lower court had violated the defendants' rights by not instructing the jury on presumption of innocence and whether reasonable doubt was essentially the same as presumption of innocence.

Justice Edward Douglas White wrote the majority opinion. For a legal historian, his analysis is a dazzling display of legal history --- even if most of it is not correct. To prove the antiquity of "Innocent until Proven Guilty" White cited a story from the late antique Roman historian, Ammianus Marcellinus, Justinian's Digest and Code, Pope Gregory IX's Decretales, a decretal of Pope Innocent III,(3) and Giuseppe Mascardi's De probationibus, all, except for Ammianus, from the continental law.(4) None of the texts, unfortunately, contained the maxim. Not one of them, you may note, was from English law. Puzzling.

When White turned to the Anglo-American tradition, he found the principle clearly articulated in a number of nineteenth-century treatises on evidence and criminal law. The jurists White cited were William Wills, († 1860) On circumstantial Evidence, Simon Greenleaf, On the Law of Evidence (1783-1853), and William Best, (1809-1869) On Presumptions. Of these jurists Best is the only one who explicitly states that it is a "maxim of law, that every person must be presumed innocent until proven guilty."

Justice White did try and trace the maxim in the English common law tradition but could only find one piece of evidence. He cited an anonymous author of an article in the North American Review of 1851 who stated that the maxim is first found in a treatise on evidence by Irish jurist named Leonard MacNally. White concluded that even "if the principle had not yet found formal expression in the common law writers at an earlier date, yet the practice which flowed from it has existed in the common law from earliest time."(5)

In Coffin v. U.S. Justice White ordained Leonard MacNally (1752-1820) as the midwife of "Innocent Until Proven Guilty's" entrance into the American common law tradition.(6) Who is he? He was born in Dublin in 1752. After his father died in 1756, he spent a part of his childhood in Bordeaux. At 19 he opened a grocery shop in Dublin. An ambitious sort, he was called to the Irish bar in 1776 and to the English in 1783. At the same time he began to write lyrics for musicals, some of which were performed in Covent Garden and other London theaters. In 1779 "The Apotheosis of Punch: A Satirical Masque" was performed, followed by thirteen other plays between 1779 and 1789. In anticipation of the pullulation of romantic medieval themes in the nineteenth century, he entitled one play "Robin Hood, or Sherwood Forest, a comic opera" and another "Richard Coeur de Lion: An Historical Romance." Although light fare, sort of a Kmart Gilbert and Sullivan, MacNally does merit a mention in The Grove Dictionary of Music.

The anonymous author of the Dictionary of National Biography's article on MacNally alleged that he was "no great lawyer" but an "astute and eloquent advocate." His dismissal of MacNally's legal skills does the Irish barrister a grave disservice. The DNB author did not realize that MacNally's The Rules of Evidence on Pleas of the Crown illustrated from Printed and Manuscript Trials and Cases, published in Dublin and London 1802 was immediately transported across the Atlantic and printed in Philadelphia 1804 and reprinted in 1811. One cannot read American treatises on evidence and presumption in the first half of the nineteenth century without stumbling over MacNally.

MacNally was particularly important for the development of rules governing evidence and procedure in criminal cases because he had represented a number of United Irishmen accused of treason. He quotes a large number of his own cases in his book. It is no fluke that treason led MacNally to consider the rules of evidence more carefully than previous writers. The cases that society has found most heinous have always been those in which the rules of fair and just procedure have come under attack.

The rules of procedure for cases of treason were still substantially different from the normal rules of criminal procedure. Even during MacNally's lifetime the same rules of due process were not extended to Irish defendants in trials of treason. Although two statutes of King Edward VI and another of William III required two witnesses for any conviction of treason, this procedural nicety was not extended to Ireland. MacNally emphasized the presumption of innocence for those accused of treason and justified applying the same rules of due process to them as to other defendants of criminal offences. His defense of Irish rights was rhetorically compelling:

If these English statutes were enacted because in cases of treason the oath of allegiance counterpoises the information of a single witness, is not an Irishman intitled(sic) to the benefit of that reason? --- or, if the principal reason for enacting those statutes was, as sir William Blackstone states, "To secure the subject from being sacrificed to fictitious conspiracies which have been the engines of profligate and crafty politicians in all ages," why should not Irishmen be granted the same security, from such conspiracies and the machinations of such politicians? The imperial parliament have to discuss and determine those questions at a future day.(7)

He never used the maxim "Innocent until Proven Guilty," but he argued vehemently for the rights of defendants, often using examples from cases in which he had participated. MacNally came very close to stating the principle when he discussed the two witness rule for cases of treason by citing Cesare Beccaria.

In Beccaria's judgment, one witness is not sufficient; for whilst the accused denies what the other affirms, truth remains suspended, and the right that every one has to be believed innocent turns the balance in his favour.(8)

A century later Justice White may have used this passage from MacNally (he does not give a specific citation) to plant the doctrine of presumption of innocence firmly in American jurisprudence.

MacNally's story does however have a darker side. After his death in 1820 the English press revealed that MacNally had played the role of a double agent since at least 1794. While he was representing Irish revolutionaries as their defense attorney in court, he was betraying them to the government by passing on key information. He relayed all the details about the revolutionary activities that he received from his clients to the government prosecutors. From 1800 until his death he received 300l. a year for his trouble. Of this side of MacNally, Justice White knew nothing.(9)

One may ask, from where did MacNally get his principles? MacNally acknowledged Beccaria, and, indeed, Cesare did extoll presumption of Innocence several times in his famous treatise, Dei delitti e delle pene (On crimes and punishments). He argued for always having two witnesses before one could be condemned for a criminal offence:

More than one witness is needed, because, so long as one party affirms and the other denies, nothing is certain and the right triumphs that every man has to be believed innocent.(10)

A few pages later, Beccaria repeated the same argument when, in the most passionate page of his tract, he assailed torture.(11)

either the crime is certain or it is not; if it is certain, then no other punishment is called for than what is established by law and other torments are superfluous because the criminal's confession is superfluous; if it is not certain, then according to the law, you ought not torment an innocent because such is a man whose crimes have not been proven.(12)

MacNally relied on Cesare Beccaria to justify presumption of innocence.(13) But the story is much longer and more complicated than the obvious link that I have shown between Beccaria and MacNally. Presumption of innocence had a long history that stretches back to the twelfth century. It is to the jurisprudence of the Ius commune to which I shall now turn in search of that presumption and the birth of our maxim.

The Ius commune was the common law of Europe from the twelfth to the seventeenth centuries. It was formed by the fortuitous and contingent conjuncture of Roman law, canon law, and, later, feudal law in the schools and courts of medieval Europe. Its birth took place in an age when momentous changes in the practice of law were taking place. Law was evolving from unwritten customary usages to written customary and legislated law. Judicial procedure was in a state of great flux. Prior to the twelfth century the judicial ordeal was a pervasive mode of proof. During the course of the twelfth century, particularly in Southern Europe, the ordeal was replaced by the ordo iudiciarius , a mode of proof that was based on Roman law, but whose rules were established by the jurists of the Ius commune.

The change from modes of proof based on the ordeal to a mode of proof borrowed from the procedural norms of Roman law was profoundly unsettling.(14) Procedure is the central part of any legal system. A society's sense of justice is intimately linked to its modes of proof. As the ordo iudiciarius was imposed on Europe's courts by ecclesiastical and secular authorities, there is clear evidence that all strata of society had questions about its legitimacy.

Medieval conceptions of rights were intimately connected with judicial procedure. Although the world of the ordeal had no jurists and no jurisprudence, that world did have the notion of presumption of innocence. Every legal system, in fact, that I know about has some notion that a defendant is presumed innocent. In Europe, literary sources, not jurisprudence, give us insight into their presumptions. In the Romance of Tristan that is part of the Arthurian cycles, King Mark condemned Tristan and Isolt to death without a trial when they were caught flagrante delicto. The poet tells us that the people of the Kingdom were dismayed because they had not been tried by the proper judicial procedure, in this case an ordeal. The people cried out: "King, you would do them too great a wrong if they were not first brought to trial. Afterwards put them to death." Tristan and Isolt had been caught with their clothes off and their defenses down. Neither they nor King Mark had ever formulated the thought: Ah, yes, I'm innocent until proven guilty, but the story of Tristan and Isolt pinpoints a crucial problem that hindered the development of a presumption of innocence in every legal system. Why should the perpetrators of flagrant, notorious, public, and observed crimes have a right to a trial? Are those whom everyone knows are guilty still deserving of a presumption of innocence?

The jurists of the Ius commune did create norms that a defendant must be canonically summoned and publicly convicted. A few texts in Roman law supported a defendant's right to be heard in court. In his famous decretal Venerabilem, Pope Innocent III stated that if defendants had not been cited, witnesses could not present testimony against them.(15) In another decretal, cited by Justice White in Coffin vs. U.S., the same Pope Innocent formulated a general presumption that a person should always be presumed to be of good reputation.(16)

Although the general principle of presumption of innocence was well established in the jurisprudence of the Ius commune by the beginning of the thirteenth century, the right was far from absolute. Notorious crimes provided the most clear infringement of the right. The jurists agreed that when a crime was heinous and notorious a judge could render a decision against a defendant without a trial. In the middle of the thirteenth century, one of the most distinguished jurists of the age, Henricus of Segusio, declared that notorious crimes, especially those committed against the Church, needed no formal juridical examination.

At the same time as jurists were creating a jurisprudence that recognized a presumption of innocence for defendants, Europe's courts were making a transition from the ordeal to the ordo iudiciarius in the twelfth century. Although founded on Roman law, the ordo was new. It takes a leap of our imaginations to understand the turmoil this change must have created. We might project this turmoil into our own lives if we could imagine how we would react if the court system suddenly replaced juries with panels of judges. Jurists of the twelfth century needed to justify the radical changes in the modes of proof that were taking place. The jurists found their justification in the Old Testament and ingeniously traced the origins of the ordo iudiciarius to God's judgment of Adam and Eve in paradise. By doing so, they created a powerful myth justifying the ordo that retained its explanatory force until the seventeenth century.

Around 1150 a jurist named Paucapalea was the first to link the ordo iudiciarius to A am and Eve. He noted that the ordo originated in paradise when Adam pleaded innocent to the Lord's accusation. In Genesis 3.9-12, the Lord burst into Paradise and demanded: Adam ubi es? One may note that for a deity his question was not particularly omniscient. Adam responded to the Lord's accusation of illegal apple picking by complaining to God that "My wife, whom You gave to me, gave <the apple> to me, and I ate it." God had, in other words entrapped Adam by giving him a wife. Paucapalea's point is subtle and was not be lost on later jurists. Although God is omniscient, he too must summon defendants and hear their pleas. Paucapalea added another piece of evidence that the ordo arose from the Bible. When Moses decreed that the truth could be found in the testimony of two or three witnesses, he pronounced a basic rule of evidence and confirmed the antiquity of a system of procedure accepted by God himself (Deuteronomy 19.15). By the second half of the twelfth century, the jurists were keenly conscious of a defendant's right to a trial and of his right to have his trial conducted according to the rules of the ordo iudiciarius --- limiting to right of the judge to act arbitrarily. Most importantly for our story, the subtext clearly implies that if God must summon litigants to defend themselves, mere humans must also summon them and presume that every defendant is innocent until proven guilty in court.

However, presumption of innocence was not yet a right. Notorious crimes still trumped presumption of innocence in the jurisprudence of the Ius commune. One more crucial change had to occur. Paucapalea's argument that the ordo iudiciarius originated in the Bible was the authoritative and powerful reason that brought about a crucial change in thirteenth-century jurisprudence. Before the middle of the thirteenth century jurists accepted the right of the prince or the judge to ignore the rules of the judicial process because they considered legal procedure to be a part of the civil law, that is positive law, and, therefore, completely under the prince's authority. Paucapalea and the canonists introduced a different story and a different paradigm. If the ordo iudiciarius can be first found in the Old Testament, and if God had to respect the rights of defendants, then the rules of procedure must transcend positive law.

The jurists were not slow to see the implications of Paucapalea's new paradigm. During the second half of the thirteenth century they began to argue that the judicial process was not derived from civil law, but from natural law or the law of nations, the ius gentium. A paradigm shift occurred. The story is interesting but complicated. So I'll skip most of it.

The main point is that once the jurists decided that the norms of procedure were part of natural law, they quickly saw that essential rights of defendants could not be transgressed. The most sophisticated and complete summing up of juristic thinking about the rights of defendants in the late thirteenth and early fourteenth centuries is found in the work of a French canonist, Johannes Monachus who died in 1313. While glossing a decretal of Pope Boniface VIII (Rem non novam) he commented extensively on the rights of a defendant. He began by asking the question: could the pope, on the basis of this decretal, proceed against a person if he had not cited him? Johannes concluded that the pope was only above positive law, not natural law. Since a summons had been established by natural law, the pope could not omit it. He argued that no judge, even the pope, could come to a just decision unless the defendant was present in court. When a crime is notorious, the judge may proceed in a summary fashion in some parts of the process, but the summons and judgment must be observed. He argued that a summons to court (citatio) and a judgment (sententia) were integral parts of the judicial process because Genesis 3.12 proved that both were necessary. God had been bound to summon Adam; human judges must do the same. Then he formulated an expression of a defendant's right to a trial and to due process with the following words: a person is presumed innocent until proven guilty (item quilbet presumitur innocens nisi probetur nocens).(17)

This sentence is the ultimate irony of the story: rather than a sturdy Anglo-Saxon, a cardinal of the Roman church, a Frenchman, a canonist, Johannes Monachus was the first European jurist to recognize the inexorable logic of God's judgment of Adam: God could not condemn Adam without a trial because even God must presume that Adam was innocent until proven guilty. Johannes' commentary on Rem non novam eventually became the Ordinary Gloss of the late medieval collection of canon law known as the Extravagantes communes. This collection and its gloss circulated in hundreds of manuscripts and scores of printed editions until the seventeenth century.(18) So -- the answer to our question, who first uttered the principle, Innocent until proven guilty -- a perfect question for the legal edition of Trivial Pursuit -- is the French canonist Johannes Monachus. Since his gloss was read by the jurists of the Ius commune to the time of Cesare Beccaria, it was a primary vehicle for transmitting the principle to later generations of jurists.

Roman law, canon law, the Ius commune: from these sources spring that great Anglo-Saxon principle: A person is innocent until proven guilty. The question remains, however, how deeply did this doctrine inform the jurisprudence and court practice of the late medieval and early modern Europe? Today I can give only a brief outline of the problem and rough sketch of the story's main features up to the time with which we began, the time of Beccaria and MacNally.

A glance at the standard accounts of procedure and law after the thirteenth century would seem to render the opinion risible that any conception of "innocent until proven guilty" existed before the eighteenth century in European jurisprudence. Inquisitorial courts searching out heresy seem the antithesis of due process and contrary to any conception of defendants' rights. Torture, secret accusations, and arbitrary procedural injustices seem the norm rather than the exception. Some scholars have argued that the courts had an obligation to punish crimes, it was a matter of public utility, and that procedural short cuts to the "truth" like torture were means through which the courts fulfilled their obligations.

So the question is, how did a defendant's right ot a presumption of innocence survive in the late medieval and early mdoern jurisprudence? It has been true in the past and remains true today that procedural rules are broken and rights violated most often when judges have faced crimes that strike society's most sensitive nerves. The cases in which I have found that the presumption of innocence discussed again and again are those that dealt with marginal groups, especially heretics, witches, and Jews.

Let me give a couple of examples. In 1398 or 1399, Salamon and his son Moyses, Jews living in Rimini, had been accused by several Christian women of having had sexual relations with them. The case was heard by a Franciscan inquisitor, Johannes de Pogiali. The case fell under the jurisdiction of the Inquisition because Salamon and Moyses had used heretical arguments to seduce the women. When the they encountered virtuous resistance from the Christian women Salamon and Moyses told them that Christian women who fornicated with Jewish men did not sin. The women testified before the Inquisition that they capitulated to Salamon and Moyses only after having been convinced by their clever arguments.(19) We do not know the facts behind this case, only its outcome as reported in the papal court. Although the bare facts might make us think of this case as material for a Boccaccian farce, Salamon and Moyses did not think the accusation was amusing. The inquisitor's summary of the case is of great interest. He called witnesses before him, examined them, and took their oaths to tell the truth. In the end he did not find that the accusations against Salamon and Moyses were juridically and legitimately proven. It is not often that we find a judge justifying his decision in the Middle Ages. In this case, Johannes de Pogiali did. He examined the facts and concluded that "it was better to leave a crime unpunished than to condemn an innocent person."(20) Many of you will recognize in these words the origins of "Blackstone's ratio": "the law holds that it is better that ten guilty persons escape than one person suffer," that entered English law from the Ius commune through Fortescue.(21)

Johannes had to choose between two conceptions of order: that crimes should be punished in the public interest or that defendants should be presumed innocent if proofs were insufficient, even in a delicate case where an outsider had violated more than just the public order.(22) Johannes also had to choose between a standard of justice for Christians and a standard for Jews. When judges and jurists asked themselves that question in the fifteenth and sixteenth century, the theoretical answer was invariably the same: Jews had the same rights of due process as Christians. And if proofs failed, they were presumed innocent. To be sure, the theory did not always find its way into the courtroom, but the rules were repeated again and again in papal mandates sent to local judges and inquisitorial courts. In 1469 Pope Paul II confirmed the petition of the Emperor Frederick III that absolved Christian judges, notaries, and scribes who participated in cases involving Christians and Jews from any wrong doing. Some Christian priests refused to absolve them from their sins unless they did penance for their roles in court aiding Jews. "Justice," Paul observed, "ought to be common to all, Christian or Jew."(23) Later popes issued decretals that specified in great detail the procedural protections that Jews must be given. A letter of Pope Sixtus IV in 1482 mandated that Jews should receive the names of their accusers, should be able to present legitimate exceptions, proofs, and defenses to the court, and, if these rights were violated, could appeal to Rome.(24) From the number of times the Roman curia repeated these admonitions over the next fifty years, theory and practice may not have always happily coincided.(25) Several sixteenth-century letters emphasized a Jew's right to a defense, to have an advocate, and to receive money from supporters for a defense in heresy and apostasy trials. As Pope Paul III declared in 1535, "no one should be deprived of a defense, which is established by the law of nature."(26) The right to a defense, a lawyer, and the means to conduct a defense was a necessary extension of the rights enshrined by the maxim "Innocent until Proven Guilty." By way of contrast, the common law did not recognize the right of a criminal defendant to counsel in treason trials until 1696.(27)

The sixteenth century became a great age for criminal law and procedure in the Ius commune. Earlier jurists had written tracts on torture, evidence, heresy and witchcraft trials, but none had written a detailed tract on criminal procedure. From the thirteenth to fifteenth centuries, treatises on criminal procedure were, with only a few exceptions, short and schematic.(28) During the sixteenth century, the jurists synthesized the jurisprudence of the Ius commune, and they wrote great tracts on the rights of criminal defendants. The names of these proceduralists are not well known: Giuseppe Mascardi, Giovanni Luigi Riccio, Giulio Claro, and Giacomo Menochio are not household names, even to legal historians. One of the great figures in this development was Prospero Farinacci who lived from 1544-1618. He was educated in Perugia and quickly discovered both sides of the bench. In 1567 he became the general commissioner in the service of the Orsini of Bracciano; the next year he took up residence in Rome as a member of the papal camera. However, in 1570 he was imprisioned for an unknown crime. Legal problems hounded him for the rest of his life. He lost an eye in a fight, was stripped of his positions, and accused of sodomy. In spite of his difficulties, Pope Clement VII reinstated him to the papal court in 1596. He began his most important work, Praxis et theorica criminalis, in 1581 and put the finishing touches on it by 1601.(29)

Farinacci's treatise bristles with the presumption of innocence. The issue arose in several different contexts. He insisted that the exception of innocence was privileged in law and could never be abolished by statute; if a statute would abolish a defendant's right to a defense, it should be interpreted as only being unjust or calumnious defenses.(30) Even the pope could not take away the right of a defendant to prove his innocence, since that right was grounded in the law of nature.(31) Like other jurists who wrote on criminal procedure, Farinacci distinguished between presumptions of law and of men: a presumption of man was, for example, that in doubt, a man was presumed to be good.(32)

Presumption of innocence and the right to be considered innocent until proven guilty were alive and well in the Ius commune during the sixteenth and seventeenth centuries. Another great voice of reason in criminal procedure was Frederick von Spee (1591-1635). Spee was a jurist, Jesuit, poet --- literary critics are still spilling ink on his most important poem, Trutznachtigall --- he was a critic of intolerance and ignorance. As Beccaria would a century later, he condemned torture, the persecution of witches, and other crimes that enraged princes and the rabble. Unfortunately for him, Europe was not yet ready for his voice of reason. He was stripped of his academic positions after the publication of Cautio criminalis, his famous treatise on procedure in witchcraft trials, condemned by his order, and died young, helping to treat soldiers infected by the plague of 1635 in Trier.(33)

"Must we assume that witches are guilty?" he asked in Cautio criminalis. "That's a stupid question," he bellowed.(34) His condemnation of torture was absolute. He took his arguments from Farinacci.(35) His rhetoric inspired Beccaria a century later:(36)

Can a defendant who does not confess under torture be condemned? "I assume," wrote Spee, "that no one can be condemned unless his guilt is certain; an innocent person ought not be killed. Everyone is presumed innocent, who is not known to be guilty."(37)

There is some irony in this part of the story too. Beccaria and Pietro Verri, Beccaria's muse who wrote a significant tract on torture published long after Dei delitti,(38) probably borrowed Spee's thought and adapted his words when they wrote about torture.(39) Yet Beccaria and Verri condemned Spee, Farinacci and other jurists at the same time that they appropriated their ideas, accusing them of being soft on torture.(40)

We have come full circle: from Justice White to MacNally to Beccaria to Johannes Monachus and back to Beccaria. The evolution of the norm that every person is presumed innocent until proven guilty is a case study of the long process through which principles of law emerge, slowly, hesitantly, sometimes painfully, in jurisprudence. The maxim, innocent until proven guilty was born in the late thirteenth century, preserved in the universal jurisprudence of the Ius commune, employed in the defense of marginalized defendants, Jews, heretics, and witches, in the early modern period, and finally deployed as a powerful argument against torture in the sixteenth, seventeenth and eighteenth centuries. By this last route it entered the jurisprudence of the common law through a thoroughly disreputable Irishman's having read a book on criminal punishments by an Italian. In a world that is choked by the narrow horizons of legal systems imprisoned by national sovereignties, this story is the best argument I know for returning to a conception of law that broad, comparative, and open to the jurisprudence of the past and the jurisprudence of other legal systems.

Luigi Firpo (Milano: 1984) 56

Venturi, "Beccaria, Cesare," Dizionario biografico degli Italiani 7 (1965) 458-469, at 461: "Argomenti vecchi, derivanti in parte de Montesquieu, ed elementi nuovi, che sgorgavano dalla personalità stessa del Beccaria, confluivano in queste pagine, tra le più chiare e persuasive uscite della sua penna."

12. Cesare Beccaria, On crimes and punishments, translated by Richard Davies and edited by Richard Bellamy, with Virginia Cox and Richard Bellamy (Cambridge Texts in the History of Political Thought; Cambridge: 1995), chapter 16, 39 (I have corrected their translation). The Italian text reads: "o il delitto è certo o incerto; se certo, non gli conviene altra pena che la stabilita dalle leggi, ed inutili son i tormenti, perché inutile è la confessione del reo; se è incerto, e' non devesi tormentare un innocente, perché tale è secondo le leggi un uomo i di cui delitti non sono provati, " ed. Luigi Firpo (Milano: 1984) 62.

Non obstantibus aliquibus privilegiis, London, BL Royal 10.E.i., fol. 214r, London, Lambeth Palace 13, fol. 363v-364r: "Et Gen. xviii. ubi factum erat notorium attamen Deus uoluit probare quam iudicare . . . Nec obstat extra. de accus. c. Euidentia <X 5.1.9>, nec ibi tollitur citatio nec sententia quia Gen. iii. probatur utrumque necessarium . . . Hinc est quod iudiciorum ordo et placitandi usus in paradiso videtur exordium habuisse. Nam Adam de inobedientia a Domino redargutus, quasi actori exceptionem obiiciens, relationem criminis in coniugem, immo in coniugis actorem convertit, dicens: Mulier quam mihi sociam dedisti me decepit . . . Item quilibet presumitur innocens nisi probetur nocens, extra. de presum. c. Dudum <X 2.23.16>."

Ibid., p. 528: "non invenit contra ipsum Salomonem fore iuridice et legitime probatum, videlicet quod ipse talia verba protulerit aut alia supradicta commiserit vel fecerit, considerans fore melius facinus impunitum relinquere quam innocentem condempnare . . . declaravit dictum Salomonem de verborum predictorum prolatione et aliorum premissorum perpetratione fuisse et esse innocentem."

22. Richard M. Fraher has argued in a series of articles that medieval procedure between 1200 and 1500 was saturated with the idea that the Ius commune dictated that it was in the public interest that crimes not remain unpunished. This conception of judicial order led to the introduction of torture and deposited the burden of proof on defendants. I think that presumption of innocence played a greater role in theory and practice than Fraher would concede. See his articles "The Theoretical Justification for the New Criminal Law of the High Middle Ages: `Rei publicae interest ne crimina remaneant impunita'," University of Illinois Law Review (1984) 577-595 and 'Conviction according to Conscience: The Medieval Jurists' Debate concerning Judicial Discretion and the Law of Proof," Law and History Review 7 (1989) 23-88.

Nicola Picardi and Alessandro Giuliani (Milano: 1996) 163: " ce conseil qu'on a acoûtumé de donner aux acusez n'est point un privilége acordé par les Ordonnances ni par les Loix que c'étoit une liberté aquise par le droit naturel, qui est plus ancien que toutes les Loix humaines. Que le nature enseignoit à l'homme d'avoir recours aux lumieres des autres, quand il ne n'en avoit pas assez pour se conduire et d'emprunter du secours, quand il ne se sentoit pas assez fort pour se défendre. . . . Que si on vouloit comparer nôtre procédure criminelle à celle des Romains et des autres Nations, ou trouveroit qu'il n'y en voit point de si rigoureuse, que celle qu'on observe en France, particuliérement dépuis l'Ordonnance de 1539."

28. Tancred of Bologna wrote one the first tracts dealing solely with criminal procedure ca. 1210-1215, see Richard M. Fraher, "Tancred's `Summula de criminibus': A New Text and a Key to the Ordo Iudiciarius," Bulletin of Medieval Canon Law 9 (1979) 23-35, edited on pp. 29-35. The most complete discussion of criminal procedure during this period was the third part of Guilielmus Durantis' Speculum iuris (2 vols. Basel: 1574; reprinted Aalen: 1975). Other influential tracts on criminal procedure can be found in volume 11 of Tractatus universi iuris (Venice: 1584).

Iul. de adult. Anan. in c. Si adversus . . . immo si statutum tollit reo defensiones, intelligitur de defensionibus iniustis et calumniosis, secus de iustis, et quae respiciunt illius innocentiam."

31. Ibid., p. 143-144, num. 15: "Et si tu subtilis diceres ergo Princeps isto casu <cases where the pope has judged someone contumacious> tollit exceptionem, et defensionem innocentiae? Qua tamen eum sit de iure naturae, nec a principe, nec a statuto tolli potest . . . Respondeo duobus modis. Primo, quod ex caussa (sic) publicae utilitatis multa potest princeps contra generales iuris regulas, praesertim ne delicta remaneant impunita, ita in his terminis respondet Carer. d. num. 89 et 99 poret Matth. et Andr. in constitu. Paenam eorum, in i. notab. . . . Respondeo secundo, quod isto casu summus pontifex non prohibuit exceptionem innocentiae, sed illius admissionem sibi reservavit, cum dicit "Nisi habita desuper asignatura nostra speciali gratia" (Cited bull of Pius V, dated to the fifth year of his pontificate on p. 143). Advertat ergo iudex isto casu, ne sit velox ad exsequendum sententiam quia si reus offert innocentiam suam docere per contrarias probationes debet supersedere et principem consulere vel exspectare, quod pro parte rei adeundum principem recurratur, isto praesertim casu, in quod prout infra dicetur, facilis esse debet idem princeps in admittendo reum ad defensiones, et si iudex aliter faceret, male faceret."
