Medical confidentiality mandates that doctors work to protect their patients’ secrets. But what happens when physicians are called upon to testify in a court of law? Upon questioning in the courtroom, are physicians ethically—or legally—justified in revealing their patients’ secrets? In the United States, the laws governing medical testimony in the courtroom are myriad and contradictory. In some courtrooms, doctors are forbidden from disclosing their patients’ secrets. In others, doctors risk being held in contempt of court if they withhold any information. New York’s statutory code protects almost all communications between doctor and patient. Massachusetts, on the other hand, requires physicians to submit to any and all questions. In California, physicians must reveal their patients’ secrets in criminal trials, but cannot in civil trials. At present, federal law is ambiguous on the subject.Footnote 1 These contradictions are a product of the unusual origins and uneven evolution of physician-patient privilege in the nineteenth century—factors not fully appreciated by medical historians or legal scholars.Footnote 2
In the United States, the origins of physician-patient privilege can be traced to the early nineteenth century. At the time, owing to a precedent originally established in the Duchess of Kingston’s 1776 trial for bigamy, no American jurisdiction recognized physician-patient-privilege. In 1828, however, the New York legislature passed a statute that barred physicians from revealing their patients’ secrets in the courtroom. With this addition to the state’s evidence laws, New York became the first state to extend medical confidentiality into the courtroom. By 1905, thirty different states or territories had followed New York’s example, incorporating physician-patient privilege into their revised legal codes.Footnote 3
Somewhat surprisingly, however, the spread of privilege statutes went largely unnoticed in the medical journals and medical textbooks of the day—unnoticed even in treatises on medical jurisprudence. Likewise, legal scholars took little note of these new laws, and, until the latter half of the nineteenth century, physician-patient privilege was, in fact, seldom exercised in the courtroom. If privilege remained an arcane and seemingly inconsequential legal doctrine even after New York and other states recognized it, why, then, did New York adopt physician-patient privilege in the first place? And why did state after state follow New York’s lead, adopting similar statutes throughout the mid-nineteenth century?
The Duchess of Kingston’s Trial and Common Law Precedent
Most legal sources maintain that physician-patient privilege was first invoked in 1776 during the Duchess of Kingston’s trial for bigamy. When asked to reveal the intimate details of a longtime client, the Duchess’s surgeon, Caesar Hawkins, bravely took a stand for the “honour of [his] profession.” Hawkins argued that medical men were entrusted with great secrets; betraying these secrets under any circumstances would damage the welfare of their patients and the honor of their profession. But the presiding judge, Lord Mansfiled, was unsympathetic, stating, “If a surgeon was voluntarily to reveal these secrets, to be sure he would be guilty of a breach of honour, and of great indiscretion; but, to give that information in a court of justice, which by the law of the land he is bound to do, will never be imputed to him as any indiscretion whatsoever.”Footnote 4 Documented in court cases and evidence manuals ever since, this brief aside by Lord Mansfield has long been cited as a foundational legal precedent that denies doctors any inherent claim to privileged communications.Footnote 5
Yet these sources have often overlooked the peculiar circumstances surrounding the Duchess’s trial. A close examination of the trial reveals that Hawkins’s attempt to invoke “professional honor” was not an appeal to widely practiced or universally recognized medical standards, but rather a suggestion that his standing at the top of the medical profession granted him privileges that would have been denied to other practitioners.Footnote 6 Hawkins, a wealthy and successful surgeon, built his career by distinguishing himself from other, more humble practitioners. He relied upon his relationships with aristocratic clients to gain social status, adopting the values and styles of the fashionable elite, including gentlemanly honor—a code of extralegal norms that governed aristocratic life.Footnote 7 When called into court to reveal the intimate details of one of these clients, Hawkins demurred, arguing that he, as an aristocratic gentleman, could not reveal secrets entrusted to him. Thus his appeal to “professional honor” was an attempt to secure the privileges of elite social status and to protect his personal relationship with the Duchess. It was not a claim that medical ethics mandated confidentiality in the courtroom.Footnote 8
The unique circumstances and timing of the case, however, allowed this brief conversation to be transformed over the course of several decades into a lasting legal precedent that seemingly addressed modern notions of medical confidentiality. The Duchess of Kingston’s trial took place in the midst of larger transformation of courtroom proceedings. Over the course of the eighteenth and nineteenth centuries, the advent of adversarial criminal trials with attorneys representing both prosecution and defense slowly led to the formation of standardized rules of evidence.Footnote 9 Lord Mansfield (whose ruling has been cited as a rejection of physician-patient privilege) was at the head of this movement, and his decisions on numerous other legal issues formed crucial precedents that helped modernize English law.Footnote 10 As the notions of gentlemanly honor subsided and the medical profession grew stronger in the early nineteenth century, legal scholars increasingly looked to the Duchess’s case—one of the best recorded and preserved trials of the era— as a legal precedent, ascribing the well-remembered case with the more modern notions of medical confidentiality and medical ethics.
Until 1828, medical witnesses in the United States were, in theory, governed by the precedent established in the Duchess of Kingston’s trial for bigamy. The matter was seldom considered in American courtrooms, however, and the few instances in which medical confidentiality was invoked in the courtroom demonstrated that American courts were often unable to reach a consensus on the issue. In Sherman v. Sherman, a 1793 divorce case, a doctor was forced to testify despite his objection that “all he could testify came to his knowledge in confidence.” Legal scholars have cited this case as proof that the precedent established in the Duchess of Kingston’s trial “would probably have been acknowledged as a common law principle in every American court.”Footnote 11 Other sources suggest, however, that some courts were willing to grant physicians privileged communications. The Medical Society of the State of New York’s System of Ethics claimed that, in 1800, the Pennsylvania courts barred the disclosure of medical secrets in the courtroom on the grounds that these communications were analogous to privileged communications between priest and penitent.Footnote 12 And yet none of these references appeared in nineteenth-century evidence manuals or became lasting precedents.Footnote 13
Instead, American legal scholars continued to look to England, where only a few judicial decisions addressed the topic of physician-patient privilege. Wilson v. Rastall, the first and most frequently cited of these British decisions, was adjudicated in 1792. A bribery suit brought before the King’s Bench, the case featured no medical testimony. Yet in the court’s decision, Justice Buller, a protégé of Lord Mansfield, delivered a brief aside that reiterated the precedent established by his late mentor:
There are cases to which it is much to be lamented that the law of privilege is not extended; those in which medical persons are obliged to disclose the information which they acquire by attending in their professional characters. This point was very much considered in the Duchess of Kingston’s case, where Sir C. Hawkins, who had attended the Duchess as a medical person made the objection himself, but was overruled, and compelled to give evidence against the prisoner.Footnote 14
Part of a lengthy monologue on attorney-client privilege, these few lines were the first to invoke Mansfield’s ruling in a court of law, showing that, within a few decades of the Duchess’s trial, the historical meaning of the brief exchange between Mansfield and Hawkins had drastically changed.Footnote 15 The conversation was no longer about gentlemanly honor. Instead, Buller’s speech articulated what has become the modern reading of the trial—that Mansfield denied Hawkins’s claims of physician-patient privilege, establishing a precedent for all common law jurisdictions. In Buller’s brief description of the trial, the exchange between Hawkins and Mansfield was stripped of its historical context and imbued with new values. What was originally a minor aside in a very controversial case suddenly became “much considered” and was preserved one of the trial’s lasting legacies. Ironically, Buller’s lament that privileged communications ought to be extended to medical practitioners helped secure this new reading of the Duchess’s trial, reaffirming that issues of privileged communications had been central to the Duchess’s case. Buller’s remarks were then cited, along with Mansfield’s ruling, in Rex v. Gibbons and Broad v. Pitt. Footnote 16
Nineteenth-century legal scholars typically cited these cases as a source of binding legal precedent that limited privileged communications to lawyers and lawyers alone.Footnote 17 In 1804, Thomas Peake’s A Compendium on the Law of Evidence cited Mansfield to argue that “[the] rule of professional secrecy extends only to the case of facts stated to a legal practitioner, for the purpose of enabling him to conduct a cause; and therefore… the statement… of a patient to his physician [is] not within the protection of the law.” Footnote 18 Similarly, Samuel March Phillips’ A Treatise on the Laws of Evidence cited both Mansfield and Buller to show that “privilege extends to the three enumerated cases of council, solicitor, and attorney, but it is confined to those cases alone.”Footnote 19 In this way, evidence manuals lifted brief asides from justices Mansfield and Buller and transformed them into an enduring legal precedent that denied any medical privilege.Footnote 20
Codification and the Introduction of Physician-Patient Privilege in New York
In the decades following the American Revolution, New York, like the rest of the union, struggled with questions of how to adapt British common law to the realities of the new republic. Some questions challenged the fundamental principles of American society—how would property relationships designed to function within a feudal, mercantilist society need to be reworked to function in an increasingly democratic and capitalist nation?Footnote 21 Others were more practical. New York’s constitution specified that all British statute law as well as all relevant common law decisions would remain in effect. The state’s constitution carved out an exception, however, for all laws and decisions deemed “repugnant to the constitution.” These were to be “abrogated and rejected.” Which laws and decisions were to be enforced and which were to be tossed out remained largely unanswered into the early nineteenth century.Footnote 22
These enduring questions were further complicated by the New York’s rapid growth. Between 1800 and 1820, the state’s population tripled. New York City emerged as the nation’s preeminent commercial center after the Erie Canal opened in 1825. The canal also facilitated rapid growth in the state’s interior. In boomtowns like Rochester and Buffalo and throughout the surrounding countryside, an emergent middle class seized opportunities to improve their social and economic status. Populated by new immigrants and Yankee migrants from New England, the region became known as the “burned-over-district” for the numerous religious revivals that swept over it. This combination of religious zeal and economic prosperity made the region fertile ground for various reform movements. Some looked outwards, advocating sweeping changes—the abolition of slavery, women’s suffrage— in the hopes of producing a more just society. Others isolated themselves from the outside world, striving for “perfection” within the enclosed confines of utopian communities.Footnote 23
Likewise, the New York legislature worked at a furious pace to regulate the state’s booming economy—in one legislative term, for example, the state passed some three-hundred forty-three new laws. One cumulative effect of all of this legislation, however, was to create a sprawling, often-contradictory body of laws. By the 1820s, the New York statutes were catalogued in nineteen different, privately published volumes, some of which approached one thousand pages. At the same time, an additional thirty volumes recorded relevant common law decisions and another seven volumes on chancery law were in circulation.Footnote 24 For lawyers and legislators faced with sorting through this morass of obscure and often-contradictory laws, it could be difficult to determine which statutes and which rulings applied to specific cases.
In order to bring clarity to the New York law, the state legislature commissioned three separate revisions of the state code.Footnote 25 Each round of revisions only added more uncertainty, however, and in 1821 the New York legislature called a convention to completely rewrite the state constitution. Gathering in Albany, delegates to the convention trimmed away sections of the state’s code that were outdated or, in some cases, “repugnant” to the principles of American democracy. Still, the vague language of New York’s new constitution did little to resolve the complications surrounding the state’s law.Footnote 26 And so, in 1824, the state legislature commissioned a three-man committee to “alter the phraseology” of the state’s legal codes and increase the legibility of the state’s statutory law.Footnote 27 The legislature asked attorneys Benjamin Butler and Erasmus Root, as well as the prominent legal scholar James Kent, to examine the state’s laws. Root and Butler accepted, but Kent declined. In his place, the legislature appointed John Duer, one of New York’s foremost private attorneys.Footnote 28
While the state legislature commissioned multiple revisions of New York’s statutory code, a small cadre of lawyers began to call for more drastic reforms. To these reformers, the problems facing New York were emblematic of larger, structural problems with the common law system. Inspired by the British legal philosopher Jeremy Bentham as well as the French Code Napoleon, these reformers believed that codification, the process of collecting and restructuring the law into singular legal code, offered a means to eschew the mysteries of a common law system based on tradition and precedent in favor of a simpler, more accessible legal code.Footnote 29 Codifiers argued that the common law was too complicated for a fledgling democracy as, in many cases, Americans did not have the knowledge necessary to represent their interests in court. Moreover, the common law, with its reliance on arcane precedents and traditions, added numerous unnecessary steps to the judicial process, making the legal system both slow and expensive. The only solution to these problems, codifiers argued, was to replace the entire common law system with a new set of codes and statutes.Footnote 30
Codification also offered the promise of Americanizing a legal system still tied to traditions and legal precedents established in Great Britain. To William Sampson—a New York attorney, an Irish-Catholic refugee, and one of the most vocal advocates of codification—the common law was a “pagan idol” imposed by British tyrants. Americans, Sampson argued, “should have… laws suited to [their] condition and high destinies.” With codified laws, the United Sates would “no longer [be] forced into the degrading paths of Norman subtleties, nor [be forced] to copy from the models of Saxon barbarity, but taught to resolve every argument into principles of natural reason, universal justice, and present convenience.”Footnote 31 In this way, codification tapped into a growing democratic sentiment in the 1820s, offering a utopian overhaul of the American legal system. Through codification, Sampson and others argued, the law would “advance with a free and unimpeded step towards perfection… [It would] be separated from the rubbish and decay of time and stripped of the parasitical growths that darken and disfigure it.”Footnote 32 If the proclamations of the most ardent reformers are to be believed, codification was, as one legal scholar put it, nothing short of “a democratic movement for access to justice—for reforming the legal system so that laypersons could not only understand, but operate the machinery of law.”Footnote 33
These reformers found powerful allies within the New York government. Governor DeWitt Clinton quickly emerged outspoken advocate of codification. In 1825, he successfully lobbied to expand the ongoing revisions of the New York legal code. Clinton empowered the revisory committee to consolidate laws relating to the same subject, to expunge expired or outdated legislation from the state code, and to suggest new laws to the state legislature. By entrusting the committee with these unprecedented powers, Governor Clinton sought nothing short of a complete overhaul of New York’s legal system—Clinton boldly asserted to the assembled legislature that he hoped to create “[a new] complete code founded on the salutary principles of the common law, adopted to the interests of commerce and the useful arts, the state of society and the nature of our government, and embracing those improvements which are enjoined by enlightened experience.” Governor Clinton hoped codification would “free [state] laws from uncertainty, elevate a liberal and honorable [legal] profession, and utterly destroy judicial legislation, which is fundamentally at war with the genius of republican government.”Footnote 34
Not everyone on the committee shared Governor Clinton’s lofty ambitions. Uncomfortable with the new powers entrusted to the committee, Erasmus Root resigned. His replacement, Supreme Court reporter Henry Wheaton served for a year before he too resigned. To fill the seat opened by these resignations, the state legislature turned to John C. Spencer, a promising young New York lawyer who had previously served in both congress and the state legislature. A longtime friend of Dewitt Clinton, Spencer shared the governor’s unwavering belief in codification. Spencer’s views on the subject were likely shaped in part by his father, Ambrose Spencer, who had long served as a judge in a New York Supreme Court and was “well known for his efforts to construct what might be called an American common law on the basis of state court rulings.” Throughout his legal career, Ambrose Spencer “often overrode English precedents in favor of what seemed to him to be commonsensical decisions appropriate to the circumstances of the new republic.”Footnote 35 A tireless worker, John Spencer quickly took control of the committee where he put his political connections to use, drafting numerous laws and working tirelessly to secure their passage through the state legislature.
Seizing this unique opportunity, the revisers used the “liberal application” of their powers to completely rewrite the New York Statutory Code. The committee compiled all of the states’ disparate statutes into a single volume, which was, in turn, split into five categories: the first dealt with issues of “internal administration and civil polity of the state;” the second contained “substantive laws relating to property domestic relations and private rights;” the third covered “the state’s judicial machinery and civil procedure;” the fourth outlined the New York’s criminal law statutes; and the fifth included “all public laws of a local and miscellaneous character.” These statutes were delivered “in simple and concise declaratory statements” and each category was presented individually to the state legislature.Footnote 36 The new Revised Statutes made numerous substantive changes to New York’s laws, reforming the state’s electoral process, making early abortion illegal, and radically reshaping the state’s property and inheritance laws.Footnote 37
The powers of the committee increased substantially when several members took on new, prestigious positions within the state government. In 1825, John Spencer was elected to the New York state senate. Three years later, Benjamin Butler was elected to the state assembly. Thus, by the time the revisers submitted their third batch of revisions on civil proceedings in 1828, both Butler and Spencer were voting members of the state legislature. From this position, the revisers defended some of their more controversial provisions. Butler, in particular, “took up multiple daily sessions in the assembly fending off objections to the revisers’ proposal to extend powers of documentary discovery and witness examination from chancery to courts of common law.”Footnote 38 In the category pertaining to civil procedure, the revisers included a new statute: “No person duly authorized to practice physic or surgery, shall be allowed to disclose any information [in court] which he may have acquired in attending to any patient, in a professional character, and which information was necessary to enable him to prescribe as a physician, or do any act for him, as a surgeon.”Footnote 39 The law was met with little objection from the state legislature, which quickly enacted the statute.
The Origins of Physician-Patient Privilege in New York
Historians and legal scholars have advanced several theories to account for this unprecedented legislation. Some hypothesized that the revisers were influenced by British legal scholarship; others suggested that prominent New York physicians managed to successfully push for adoption of the statute.Footnote 40 Yet, as one historian writes, “the exact circumstances of the introduction of this statute are not known.”Footnote 41 Any attempt to uncover these circumstances must begin with an examination of the revisers’ published notes.
The revisers were well aware that their new law regarding physician-patient privilege challenged accepted legal precedents. As with all of their potentially controversial provisions, the committee kept careful notes, justifying their actions in case of potential opposition within the legislature. In their notes, the revisers provided the legislature with a lengthy argument in favor of the new statute. They began by citing Wilson v. Rastall, stating, “[Justice] Buller (to whom no one will attribute a disposition to relax the rules of evidence) said it was ‘much to be lamented’ that [medical communications were] not privileged.” The statute was modeled upon attorney-client privilege and passed alongside a companion statute that also privileged to communications between priest and penitent. Yet the revisers saw the need to privilege medical communications as more pressing than the need to privilege communications between attorney and client:
The ground on which communications to counsel are privileged, is the supposed necessity of the full knowledge of the facts, to advise correctly, and to prepare for the proper defense or prosecution of a suit. But surely the necessity of consulting a medical adviser, when life itself may be in jeopardy, is still stronger. And unless such consultations are privileged, men will be incidentally punished by being obliged to suffer the consequences of injuries without relief from the medical art, and without conviction of any offence.
Moreover, the revisers feared that physicians, if torn between conflicting obligations, would choose to protect their patients in any event, disobeying the courts in the process:
Besides, in such cases, during the struggle between legal duty on the one hand, and professional honor on the other, the latter, aided by a strong sense of the injustice and inhumanity of the rule, will, in most cases, furnish a temptation to the perversion or concealment of truth, too strong for human resistance.
Given the support of prominent legal scholars and physicians’ desire to protect their patients, the revisers urged the state legislature to adopt the privilege immediately. The revisers concluded, “In every view that can be taken of the policy, justice or humanity of the rule, as it exists, its relaxation seems highly expedient.” They also suggested that the proposed law was “so guarded that it can not be abused by applying it to cases not intended to be privileged.”Footnote 42
Still, the Reviser’s Notes do not completely illuminate the reasons a few New York lawyers suddenly felt the need to entrust doctors with unprecedented legal privileges. One possibility is that a small group of influential New York physicians managed to convince the revisers to enact a statutory guarantee of physician-patient privilege. Five years before the New York State Legislature enacted the United States’ first medical confidentiality law, the Medical Society of the State of New York (MSSNY) had openly called for physician-patient privilege in its System of Ethics. Comparing physicians to Catholic priests, the System of Ethics suggested that physicians were obliged to maintain patient confidences even in a court of law. Written by several prominent physicians, this document may very well have informed the committee’s decision to enact physician-patient privilege.Footnote 43
Moreover, the revisers sought the council of the MSSNY’s president, Theodoric Romeyn Beck, for guidance on the revised code’s application to medical policy. Beck, an Albany physician, was already recognized as the nation’s foremost scholar of medical jurisprudence, and as one of Albany’s most prominent citizens, he was also well acquainted with the members of the revising committee, especially John C. Spencer. Beck and Spencer had both attended Union College, graduating one year apart. Each was a close friend of Governor Clinton. Historian James Mohr has demonstrated that Beck worked closely with the revisers—none of whom were experts on medical issues—to revise New York’s medical laws.Footnote 44 Though much of the communication between Beck and the revisers was likely conducted in private, excerpts from Beck’s personal correspondence reveal the extent to which Beck was involved in the process of revision:
Albany, Sept. 11, 1828
I have prepared various Sections against medical malpractice according to your Suggestions, particularly the improper use of instruments, capital operations in surgery, selling poisons &c. which when examined by Mr. Butler I will have edited and sent to you. In the mean while I want you to prepare the public and particularly the Legislature, by communications in the different newspapers, by extracts from approved writers on such subjects, and by such other means as occur to you, for a favorable examination and discussion upon our provisions. I have neither the time nor ability to do it.
Yours very respectfully,
J. C. Spencer
To Mohr, this “letter makes clear the fact that Beck was given a reasonably free hand to try to insinuate into the proposed legal code any medically related provisions he wanted.”Footnote 45 At the same time, Spencer entrusted his friend and colleague to curry the favor of state legislators, suggesting that Beck was actively involved in nearly every phase of the process. Furthermore, the law itself as well as the justification presented in the Revisers’ Notes expounded upon many of the themes present throughout Beck’s work. Mohr makes a compelling argument that Beck was responsible for another new section of the code, a section that criminalized the performance of early term abortions. But was he also responsible for inserting the statute guaranteeing physician-patient privilege into the revised code?
A closer examination of Beck’s publications provides no evidence that physician-patient privilege, unlike early abortion, was an issue that concerned him. The initial 1823 edition of Elements of Medical Jurisprudence, Beck’s seminal work, featured little discussion of the duties facing medical witnesses. In 1828, Beck addressed the Medical Society of the State of New York on the subject of medical testimony in the courtroom, but again did not mention privileged communications.Footnote 46 Thus, while Beck might have been involved, he never publicly advocated in favor of physician-patient privilege before the law was passed. Moreover, in later editions of Elements of Medical Jurisprudence, Beck did mention the precedent established in the Duchess of Kingston’s trial, but failed to mention New York’s medical confidentiality law.Footnote 47
Beck’s silence on the subject of medical privilege makes it impossible to argue that the first law extending medical confidentiality into the courtroom was the work of the medical profession. This was not a simple oversight on Beck’s part, but rather, paradigmatic of the field of medical jurisprudence as a whole. No surviving student notebooks on medical jurisprudence from the early nineteenth century “contained instruction about how information being conveyed to the students was supposed to be presented in actual courts of law.”Footnote 48 Likewise, Beck’s silence also rules out the possibility that the MSSNY successfully lobbied for the inclusion of physician-patient privilege in the Revised Statutes. If the society was responsible for this legislation, then surely Beck, as the MSSNY’s president and foremost expert on medico-legal issues, would have known about the new law.
Instead, the Revisers’ Notes suggest that the New York statue was prompted by nineteenth-century legal scholarship. The language in the revisers’ notes echoed the language of earlier court cases and legal manuals rather than medical texts. The revisers specifically referred to physicians’ “professional honor”—language lifted from the Duchess of Kingston’s trial for bigamy. Likewise, the reviser’s cited Justice Buller’s aside in Wilson v. Rastall and the legal scholar Samuel March Phillips. They did not cite any physicians or medical experts. Likewise, the revisers justified their changes to the New York code, by comparing physician-patient privilege to attorney-client privilege, not priest-penitent privilege as the MSSNY had done. Moreover, while much of the legislation proposed by Beck was placed in the medical section of the code, New York’s privilege statute was included in the state’s evidentiary code, a topic on which neither Beck nor the MSSNY were likely to have been consulted.
Furthermore, the revisers would have had their own reasons to take issue with the common law position on physician-patient privilege. To the proponents of codification, judicial decisions like Lord Mansfield’s ruling on physician-patient privilege were symptoms of two of the major problems plaguing the judicial system. First, as unelected officials, judges were afforded too much power to interpret and enforce the laws. Second, the common law, which depended upon the interpretation of legal precedent, was virtually incomprehensible to laymen. Replacing this arcane legal doctrine with a precise and proscriptive law would have solved each of these dilemmas. In their efforts to compress New York law into one coherent volume, the revisers often replaced the language of early statues with text pulled from “judicial exposition” and “professional criticism” where they believed it made the law more coherent.Footnote 49 Given the reasoning offered in the Reviser’s Notes, it is likely that the revisers, influenced by the frequent recording of Justice Buller’s lamentation in Wilson v. Rastall in nineteenth-century evidence manuals, simply believed physician-patient privilege to be an uncontroversial and commonsensical correction of a trivial legal matter.Footnote 50
Codification and the Spread of Physician-Patient Privilege
Whatever the motivations of the New York revisers, their statute quickly influenced other states to follow suit.Footnote 51 Missouri passed a law guaranteeing physician-patient privilege in 1835. Mississippi enacted a statute the following year.Footnote 52 By 1840, both Arkansas and Wisconsin had enacted statutes. Significantly, each of these states—like New York—passed their statutes guaranteeing physician-patient privilege as part of larger processes of codification, often using New York as an example.
For the most part, these laws echoed the language of New York’s statutory provision. In Missouri, the legal code stated that no physician “shall be required or allowed to disclose” patients’ confidences. Though the states’ revisers added the word required to the statute, this minor alteration did little to change the effect or intent of the law.Footnote 53 Mississippi adopted the New York statute word-for-word. Other states made minor alterations. Moreover, the revisers of later codes often had connections to New York’s legal establishment. The revised codes of both Michigan and, later, Arizona, for example, were both written by William Thompson Howell, an attorney who had practiced in New York.Footnote 54 Elsewhere physician-patient privilege was proposed, but not enacted. In the 1830s, the Massachusetts State Legislature debated a privilege statute identical to New York’s 1828 law as part of a larger codification movement. When attempts to codify Massachusetts law stalled, however, the proposed privilege statute was scrapped and quickly forgotten.Footnote 55
Only Wisconsin and Arkansas made changes that affected the potential applications of the privilege in court. Each of these states replaced the New York statutory prohibition on disclosing patients’ secrets with a weaker provision that merely prevented doctors from being compelled to reveal their patients’ secrets. For example, the Wisconsin statute read: “No Person duly authorized to practice physic or surgery, shall be compelled to disclose any information which he may have acquired in attending any patient in a professional capacity and which information was necessary to enable him to prescribe for such patient as a physician or do any act for him as a surgeon.”Footnote 56 Legal scholars have attributed this change in language to the authors’ desire to limit the power of the privilege.Footnote 57 In time, doctors would come to embrace these statutes as their language left decisions about the admissibility of medical secrets open to the interpretation of physicians. The Wisconsin statute would later serve as model as physicians lobbied for new privilege laws in the late nineteenth century.Footnote 58
Calls for codification only intensified in the 1840s. When New York adopted a new constitution in 1846, the state legislature commissioned two committees—one to reform the state’s legal practice and another to assess the possibility of further codification. A series of political compromises placed the pro-codification attorney David Dudley Field at the head of these reform movements.Footnote 59 Like Spencer two decades earlier, Field was committed to simplifying and improving New York’s legal system. He took issue with the lack of uniformity in the ways cases were brought and pleaded before the state’s courts, arguing that the state’s myriad common law precedents should be replaced with a uniform and easily accessible code of procedure.
In 1848, Field and his colleagues presented the New York State Legislature with a revised Code of Civil Procedure. Modeled upon the French Civil Code, Field’s Code of Civil Procedure took issue with the complexity and confusions of the common law as well as the jargon and Latin that underpinned nineteenth-century legal procedure. He posited, for example, that the new Code of Civil Procedure should replace “habeas corpus” with a “writ of deliverance from prison.” Even more than the revisions of the 1820s, the Field code, as one legal historian wrote, was “a colossal affront to the common-law tradition.”Footnote While the state legislature rejected some of Field’s most radical proposals, the bulk of Field’s Code was accepted into law in 1848.Footnote 61
Field’s Code did not change New York’s medical confidentiality law.Footnote 62 The 1848 revisions did, however, spark a new wave of codification that brought similar statutes to still more jurisdictions, especially in the western United States. Compared to the older eastern states, the American west featured a young, progressive bar, greater exposure to civil law, and less rigidly established common law traditions—characteristics that made these states especially receptive to codification. California adopted Field’s Code in 1851, adopting physician-patient privilege in the process. Other western states followed California’s lead with identical statutes. In the following decades, Iowa, Minnesota, Indiana, Ohio, Washington Territory, Nebraska, Wisconsin, and Kansas all adopted the code. By the turn of the century the Dakotas, Idaho, Arizona, Montana, Wyoming, North Carolina, South Carolina, Utah, Colorado, Oklahoma, and New Mexico had all adopted Field’s Code of Civil Procedure.Footnote 63
Some of these jurisdictions, like Missouri and Wisconsin had already adopted physician-patient privilege. In those states, the existing statutes were incorporated into the new Code of Civil Procedure. In many more jurisdictions, however, physician-patient privilege was adopted as part of Field’s Code. Among others, California, Kansas, and Indiana adopted physician-patient privilege in this manner. At the same time, however, numerous states rejected the Field’s controversial code altogether. Much of the eastern seaboard remained what one legal scholar termed, “common law states.” Rejecting codification, these “older states, particularly of English origin, [stuck] to the common law, and never attempt[ed] to define it, rarely even to improve it by statute.” These states remained bound to the precedent established in the Duchess of Kingston’s trial for bigamy.Footnote 64
Conclusion
The middle of the nineteenth century brought more legislation on physician-patient privilege than any time before or since. Between 1828 and 1870, seventeen states or territories enacted statutory guarantees of medical confidentiality. While all of these statutes have been amended and changed numerous times since the nineteenth century, these early statutes form the basis for modern physician-patient privilege. With the exception of Mississippi, none of these statutes was ever repealed. Instead, the effects of these early statutes continue to shape the intersections between medicine and the law today. By and large, privilege is observed where it was adopted in the nineteenth century and is not observed in the few Southern and New England states that did not adopt it. Moreover, by adopting privilege via statute, these laws had the effect of cementing the absence of privilege in federal courts which remain to the present time still tied to the common law precedent.
A thorough review of these early statutes reveals that physician-patient privilege first emerged as an inadvertent byproduct of numerous codification movements. Though there were small variations between individual statutes, by and large, all of these laws shared a common language that had been inherited from earlier legal scholarship. More importantly, each statute was enacted as part of a larger scheme of codification. Physician-patient privilege appeared in jurisdictions where codification was most popular and remained absent where codification failed to take hold. By the latter half of the century, the dividing line that would characterize later debates over physician-patient privilege had been set. Western States, most of which embraced Field’s Code of Civil Procedure, almost all guaranteed medical confidentiality in the courtroom. Eastern States, on the other hand, remained reluctant to enact physician-patient privilege.
And yet, many of these developments went unnoticed in their time. Throughout much of this period, both doctors and lawyers viewed the privilege as a legal issue and, as such, it was often overshadowed by other legal developments. For legal scholars, codification carried so many pressing implications that physician-patient privilege seemed trivial by comparison. Legal records show that, despite the rapid spread of privilege statutes throughout the mid-nineteenth century, privilege was seldom invoked in the courtroom. The subject was scarcely covered in the legal literature of the day, and, until the late 1870s, only a few cases—all adjudicated in New York—appear in any of these sources.Footnote 65 Moreover, in these cases, the courts often contradicted one another as doctors, lawyers, and judges were all unsure as to how privilege was to be interpreted in the courtroom.Footnote 66
At the same time, doctors—seldom trained in how to carry themselves in the courtroom—often failed to notice slight changes in states’ evidentiary codes. In 1831, several doctors wrote to the American Journal of Medical Sciences asking, “Are there certain questions which a medical man in a court of justice may refuse to answer?” It was a novel question—such issues were seldom discussed in the medico-legal literature of the day—and Isaac Hays, the journal’s editor, was at a loss as to how to answer this query. Hays examined a variety of different sources including records of the Duchess of Kingston’s trial for bigamy and Wilson v. Rastall and came to the conclusion that “that medical persons have no privilege whatsoever, not to disclose circumstances revealed to them professionally,” failing to note that, in New York, such communications were expressly barred by statute. This makes it all the more surprising that a decade later Hays would go on to become one of the most vocal champions of physician-patient privilege. In the 1840s, Hays took the lead in the drafting of the American Medical Association (AMA)’s Code of Ethics—a document that championed physician-patient privilege as the logical extension of physicians’ duty to preserve confidentiality. Here, Hays wrote, “Secrecy and delicacy, when required by peculiar circumstances, should be strictly observed… . The force and necessity of this obligation are indeed so great, that professional men have, under certain circumstances, been protected in their observance of secrecy by courts of justice.”Footnote 67
The AMA Code of Ethics marked an important turning point in the history of physician-patient privilege. The formal recognition of physician-patient privilege by what would become the nation’s most powerful medical society was the culmination of a decades-long process in which physicians came to view privilege as both an essential part of the physician-patient relationship and a useful tool for advancing the status of the medical profession. In the ensuing decades, the same doctors that championed the AMA Code of Ethics would publicly advocate for the spread of physician-patient privilege. To these physicians, privilege was the logical extension of the AMA Code and its emphasis on gentlemanly honor. It was also a powerful signal that the ethics and values of the regular physicians carried beyond the medical profession, as it suggested that the physician-patient relationship could be more important than the fact-finding mission of the courts.
Only through this later process, did privilege take on many of the associations it holds today. In arguing for physician-patient privilege in the late-nineteenth century, doctors came to associate the privilege with the status and prestige of their profession. Likewise, in the early twentieth century, privilege came to be associated with modern notions of privacy and patients’ rights. It is noteworthy, however, that both of these developments came much later, long after privilege had spread throughout much of the United States. In order to understand the origins of physician-patient privilege it is imperative to detach the privilege from these modern associations. With a few exceptions, the earliest advocates of physician-patient privilege were neither physicians nor patients, but instead a small group of lawyers intent on a larger agenda of codification. Perhaps because of these origins, physician-patient privilege remains an unevenly applied rule in American courtrooms to this day.
