Wilk v. AMA

The case that ended the boycott and refused to rule on the doctrine

Wilk v. American Medical Association was the federal antitrust case in which four licensed chiropractors proved that the AMA had conspired to contain and eliminate their profession. Judge Susan Getzendanner held on September 25, 1987 that the AMA violated Section 1 of the Sherman Act, and the Seventh Circuit affirmed on February 7, 1990. The court struck the boycott down and expressly declined to rule on whether chiropractic was scientific, leaving that question to the work that followed and to the Unified Model of Tone.

THE RULING

A federal judge found that the American Medical Association ran an illegal boycott of chiropractors

On September 25, 1987, Judge Susan Getzendanner of the United States District Court for the Northern District of Illinois held that the American Medical Association had violated Section 1 of the Sherman Act. The finding was narrow and it was total. The AMA had conspired with its own members to boycott an entire licensed profession, and the court fixed the period of that conspiracy at 1966 to 1980. The case was Wilk v. American Medical Association, docket No. 76 C 3777. Four licensed chiropractors brought it: Chester A. Wilk, James W. Bryden, Patricia A. Arthur, and Michael D. Pedigo. The reported decision sits at 671 F. Supp. 1465.

Ask what a finding like that actually commits you to. It does not commit you to a verdict on chiropractic theory. The court refused that question in 1987 and the Seventh Circuit refused it again in 1990. What the ruling establishes is procedural, and it is enormous. A trade association may hold any opinion it likes about a rival method. It may not organize its members so that contact with that method becomes a breach of ethics. That distinction is the whole case, and almost everything written about Wilk since has blurred it.

NOVEMBER 1963

The Committee on Quackery was a real committee with minutes, a chairman, and a budget

In November 1963 the AMA authorized the formation of the Committee on Quackery inside its Department of Investigation. This is a finding of fact from a federal bench trial, not a rumor circulated by the profession it targeted. Getzendanner traced the intent back further still. In 1963 the AMA hired as its general counsel the author of the Iowa Medical Society plan to contain chiropractic in Iowa. By September of that year, she found, the AMA objective was the complete elimination of the chiropractic profession. By 1964 the Committee had settled on its primary goal, which was to contain and eliminate chiropractic.

H. Doyl Taylor chaired the Department of Investigation through the 1960s and into the 1970s. The court found that he described the Committee prime mission, repeatedly and in writing, as the containment and elimination of chiropractic as a recognized health care service. Taylor denied it by video deposition and said he had only ever meant to eliminate a health hazard. Getzendanner called that explanation incredible and unworthy of belief. His stated view was that chiropractic rested on a single cause and single cure theory of disease, and that on so baseless a foundation the entire profession should be swept away.

THE MECHANISM

The boycott ran on one sentence of medical ethics, and nobody ever had to enforce it

The instrument was Principle 3 of the AMA Principles of Medical Ethics. It barred a physician from voluntarily associating with anyone who failed to practice a method of healing founded on a scientific basis. The AMA then closed the circle in two moves. In 1966 the House of Delegates passed a resolution calling chiropractic an unscientific cult. In 1967 the Judicial Council issued an opinion under Principle 3 holding that professional association with chiropractors was unethical. Association was read broadly. Getzendanner listed what it covered: referring patients to chiropractors, accepting referrals from them, providing diagnostic, laboratory or radiology services, teaching chiropractors, and practicing together in any form. The opinion appeared in the 1969 Opinions and Reports of the Judicial Council and went out to 56 medical specialty boards and associations. A 1971 Committee report to the Board of Trustees called the policy statement the necessary tool for widening the base of the campaign. It added that the report was meant for the Board alone, because publicity would be unwise.

No physician was ever disciplined under Principle 3, and the court held that this did not matter. The Seventh Circuit had disposed of the argument in 1983, leaning on the Supreme Court decision in Goldfarb v. Virginia State Bar. Where a professional association publishes an ethical standard, members comply so that they do not discredit themselves by departing from professional norms. A court may therefore find an illegal refusal to deal even without coercive enforcement. Getzendanner put the point plainly after hearing the witnesses. A principle of medical ethics, she wrote, is inherently a forceful mandater of conduct, and no honest professional wants to risk the stigma of being labeled unethical. Sit with that for a moment. The most effective restraint in a fourteen year antitrust case was not a fine and not a license revocation. It was a published sentence that made a colleague untouchable.

A physician should practice a method of healing founded on a scientific basis; and he should not voluntarily professionally associate with anyone who violates this principle.

THE HOSPITAL DOOR

Standard X carried the ethics bar into hospital accreditation

In 1973 the AMA drafted Standard X, which wrote the unscientific practitioner bar into the accreditation standards of the Joint Commission on Accreditation of Hospitals. The AMA urged adoption and JCAH complied. Keeping chiropractors out of hospitals was one of the declared goals of the boycott. Chiropractic had just been brought under Medicare in 1973, and the AMA grew concerned that reimbursement would open the way to hospital staff appointments. Doyl Taylor had the AMA Office of General Counsel publish an article in the Journal of the American Medical Association titled The Right and Duty of Hospitals to Exclude Chiropractors (Simonaitis 1973). It told every hospital attorney in the country that accreditation might be lost if the hospital dealt with chiropractors.

The effects on daily practice were concrete, and the Seventh Circuit had already listed them in 1983. Referrals were inhibited. Research collaboration and the sharing of clinical experience were discouraged. Requests by individual plaintiffs to use laboratory and x-ray facilities were refused, and requests for hospital inpatient privileges were denied. Public demand for chiropractic services was negatively affected. The defense economist, William J. Lynk of Lexecon, conceded the economic shape of the harm. Forcing chiropractors to buy their own x-ray equipment rather than use hospital radiology raised their costs. Preventing physicians from teaching or lecturing to chiropractors blocked them from improving their education in a professional setting.

THE FIRST TRIAL

A jury sided with the AMA, and the Seventh Circuit threw the verdict out

The complaint was filed in 1976 under Sections 1 and 2 of the Sherman Act, and it asked for damages as well as an injunction. The first trial ended in a jury verdict for the defendants. The Seventh Circuit reversed that judgment in Wilk v. American Medical Association, 719 F.2d 207, decided 19 September 1983 and known ever since as Wilk I. The error was in the instructions. The jury had been allowed to weigh a generalized public interest motive instead of confining itself to the patient care motive and the effect of the conduct on competition.

Wilk I also set the frame for everything that followed. It declined to treat Principle 3 as a per se violation, holding that a canon of medical ethics addressing the importance of scientific method raises questions of sufficient delicacy and novelty to escape that treatment. It applied the rule of reason drawn from Chicago Board of Trade v. United States, 246 U.S. 231 (1918). And it built the patient care defense, which put four burdens on the defendants. They had to show a genuine concern for scientific method in the care of each patient. They had to show the concern was objectively reasonable. They had to show it was the dominant motivating factor behind Principle 3 and the conduct implementing it. Finally, they had to show the concern could not have been satisfied in a way less restrictive of competition.

MAY AND JUNE 1987

The plaintiffs gave up the money to get the injunction

Shortly before the retrial the plaintiffs waived their claim for damages and sought only injunctive relief under Section 16 of the Clayton Act. That one decision changed the character of the case. It turned a jury trial into a bench trial, and it moved the question from the past into the present. The court would no longer be asking what the boycott had cost between 1966 and 1980. It would be asking whether the effects of the boycott were still running in 1987, because Section 16 requires a real threat of future violation or a contemporary violation likely to recur.

The case was reassigned to Getzendanner on May 4, 1987 for the purpose of conducting the trial, which ran through May and June. The record came to 3,624 pages of transcript, roughly 1,265 exhibits, and excerpts from 73 depositions. Her opinion ran 101 pages. It issued on August 27, 1987, and a substituted opinion dated September 25, 1987 became the reported decision. Two dates therefore attach to the same ruling, which is why sources disagree about when Wilk was decided.

THE DEFENSE

The AMA proved genuine concern and dominant motive, and lost the case on objective reasonableness and less restrictive means

Most retellings skip this part, and skipping it makes the case look simpler and less interesting than it is. Getzendanner found that the AMA genuinely entertained a concern for scientific method in patient care. In the same years it attacked chiropractic, she noted, the AMA also attacked other unscientific treatments, including the Krebiozen cancer therapy. Other medical societies kept similar prohibitions, and so did the chiropractic bodies. She then found that this concern, rather than economics, was the dominant motivating factor, while noting there were too many references in the record to chiropractors as competitors to ignore.

The defense collapsed on the second and fourth elements. The Committee on Quackery had evidence in front of it that chiropractic was effective, and in workers back injuries more effective than medical care. It also knew that some physicians thought chiropractors better trained in musculoskeletal problems than most of their own colleagues. The Committee did not follow up on any of it. Its members, the court found, did not have minds open to pro-chiropractic argument or evidence. So the concern could not be called objectively reasonable across the entire span of the boycott. On the fourth element the AMA offered no evidence that public education or any other less restrictive approach had been tried and failed. A nationwide conspiracy against a profession licensed in all fifty states was not the only available way to defend scientific method.

This finding is not and should not be construed as a judicial endorsement of chiropractic.

THE LIMIT

The court declined to rule on whether chiropractic was scientific

Getzendanner said so directly and more than once, and the Seventh Circuit repeated it on appeal. She excluded the 1979 report of the New Zealand Commission of Inquiry as evidence of the truth of its conclusions. She found it untrustworthy after reading the appraisal prepared by the Office of Technology Assessment of the United States Congress. Of the five randomized trials the Commission considered, only two involved chiropractic services, and both carried significant design flaws. The report came in for one narrow purpose, which was to show what information about chiropractic was available in the second half of 1979.

She recorded the unflattering evidence too. There was testimony that the chiropractic theory of subluxations was unscientific. A study showed that the original named plaintiffs did not use common methods for common symptoms. There was evidence of cranial adjustments offered as a cure for cerebral palsy. She recorded the other side of the ledger with equal care. Dr. Alan R. Nelson, then chairman of the AMA Board of Trustees, testified that some forms of manipulation delivered by chiropractors do have a scientific basis. Every party, plaintiffs included, agreed that chiropractic treatment of cancer, diabetes, heart disease, high blood pressure and infectious disease is improper, and that the historic single cause theory of disease was wrong.

SEPTEMBER 25, 1987

The remedy was publication

The permanent injunction reached the AMA, its officers, agents and employees, and everyone acting in concert with them. They were barred from restricting or impeding the freedom of any AMA member, institution or hospital to decide individually whether to associate professionally with chiropractors, chiropractic students, or chiropractic institutions. Professional association was defined to include referrals, consultations, group practice, treatment and diagnostic privileges in hospitals, teaching in chiropractic colleges, and cooperation in research and continuing education. The order expressly protected the AMA right to take and publicize positions on chiropractic and to petition or testify before public bodies. The restraint fell on collective action, not on speech.

The enforcement machinery was deliberately public, because the injury the court identified was reputational and informational. The AMA had to mail the order to every member and employee within thirty days, and it had roughly 275,000 members. It had to publish the order in JAMA and index it under Chiropractic so that anyone could find it later. It had to write its present position on chiropractic into the reports and opinions of the Judicial Council. It had to file proof of compliance by January 10, 1988. In the three days before the order issued, the American College of Radiology and the American College of Surgeons settled, each paying $200,000, the surgeons directing their payment to Kentuckiana Children Center in Louisville. Claims against JCAH, the American College of Physicians, the American Academy of Orthopedic Surgeons and Dr. James H. Sammons were dismissed, and the Section 2 monopolization claim went with them.

The district court's form of injunction and method of ensuring its publication (and thus its efficacy) was a reasonable attempt at eliminating the consequences of the AMA's lengthy, systematic, successful, and unlawful boycott.

Judge Daniel Manion · Wilk v. American Medical Association, 895 F.2d 352 (7th Cir., February 7, 1990)

THE APPEAL

The most quoted line in the case comes from 1990, not 1987

The Seventh Circuit affirmed on February 7, 1990, in an opinion by Judge Daniel Manion, joined by Judges Harlington Wood Jr. and Kenneth Ripple, argued more than a year earlier on December 1, 1988. Rehearing and rehearing en banc were denied on April 25, 1990. The Supreme Court denied the AMA petition for certiorari on November 26, 1990 (498 U.S. 982), fourteen years after the complaint was filed. The phrase everyone repeats, “lengthy, systematic, successful and unlawful boycott”, belongs to that appellate opinion. It does not appear in Judge Getzendanner opinion, and attributing it to her is the single most common error in the literature.

The appellate court was as careful as the trial court about the limit. Neither the district court nor this court is equipped to determine whether chiropractic is scientific, Manion wrote. He declined what he called yet another invitation to decide whether chiropractic is good or bad, efficacious or deleterious, quackery or science. Affirmance did not settle the doctrine. It settled the market conduct. That is a smaller holding than the profession often claims, and a more durable one.

WHAT IT SETTLES

The case protects plurality of practice, not any doctrine

Nothing in the 101 pages uses the word tone. That reading is ours, and it should be stated as ours rather than smuggled in as a finding of fact. What the case protects is the precondition for any work with tone at all. One clinician must be free to speak to another, refer to another, teach another, and share a laboratory with another, without an ethics rule standing in the doorway. Tone is the living state of the nervous system, expressed as tissue tension at every scale. No profession owns access to it, and no profession can be granted a collective veto over who approaches it.

Wilk v. AMA did not certify a doctrine. It removed a collective veto over which doorway a person may walk through. That is the contribution this page makes to the wider story, and it cuts both ways. The court refused to bless chiropractic on anecdote, and it observed that the controlled study the AMA House of Delegates had itself called for in 1980 had never been done. Fourteen years of litigation ended with the field open and the question unanswered. Answering it fell to the trials, guidelines and imaging studies of the decades that followed, which is where the evidence era begins.

WILK AND THE MODEL

The court ended the boycott, and the model dissolves the premise the boycott rested on

The injunction settled conduct and left the belief underneath it standing. That belief was that only one profession could be correct about the body, and that the others were either trespassing on real clinical science or hiding behind pseudo-scientific vocabulary. The healing professions had spent decades defending their territory against each other, often with genuine hostility, and the Committee on Quackery was that hostility written into a budget line. The Unified Model of Tone does not appeal the verdict. It rejects the belief. The professions are dialects describing a single phenomenon, told from many perspectives, and the phenomenon is tone.

The model reaches that position from the clinical record and states its step as an inference rather than a finding. Skilled practitioners in traditions that disagree about mechanism produce results whose common features are hard to miss. The list repeats across traditions: reduced pain, improved posture, better breath, more energy, deeper sleep, emotional release, restored movement, and the sense of being more at home in one body. When the physician sees labs normalize, the psychologist sees dread lift, and the chiropractor sees a body unwind, they are watching one system move through the same arc of change, recorded in three vocabularies. When methods built on incompatible theories produce the same arc of recovery, the most parsimonious explanation is that they act on one underlying system.

The sharpest objection is that they converge because none of them does anything specific, and that expectation and time account for the whole result. That objection restates the argument rather than escaping it. Expectation and time are inputs, and an input produces a result only by being received by something that changes state. Naming that something is the entire task, and the model names it tone.

The claim is built to be checked. Tone shows itself wherever a rhythm can be measured for more than its average. It appears in the variability structure of a signal rather than its mean, and in the coupling between slow and fast rhythms rather than either alone. It shows in the responsiveness of a reflex, and in the time a system takes to return to baseline after a demand. The model predicts that those four measures, recorded together in the same subjects, will share a common underlying factor rather than varying independently. Loading together on that factor establishes tone as one variable and confirms the unification on its own terms.

None of this is in the 101 pages, and the model asks the court for no ruling it declined to give. The extension is the model. The record is the record. What the case did was open a door that an ethics rule had held shut since 1966. The model reads the future on the other side of that door as many professions working the same system together, each fluent in its own access point, rather than one prevailing over the rest. A court can open a door between two rooms. It cannot tell the occupants they were always standing in the same one.

WHAT THE RECORD SHOWS

Fourteen years of litigation ended the conduct and left the scientific question open

  • November 1963. The AMA established the Committee on Quackery, a standing committee with minutes, a chairman and a budget, whose stated purpose included the containment and elimination of chiropractic (719 F.2d 207).
  • 1966 to 1980. The boycott ran on Principle 3 of the AMA Principles of Medical Ethics (719 F.2d 207), a single ethics sentence that made professional association with chiropractors unethical and that never had to be enforced to work.
  • September 25, 1987. Judge Susan Getzendanner held in Wilk v. American Medical Association, 671 F. Supp. 1465, that the AMA violated Section 1 of the Sherman Act, and issued a permanent injunction against the AMA, the American College of Surgeons and the American College of Radiology.
  • Damages waived. The plaintiffs gave up their damages claim shortly before the 1987 retrial and sought only an injunction under Section 16 of the Clayton Act. The American College of Radiology and the American College of Surgeons each paid 200,000 dollars in settlements reached in the final days before the injunction issued.
  • February 7, 1990. The Seventh Circuit affirmed at 895 F.2d 352 in an opinion by Judge Daniel Manion, which is where the line about a lengthy, systematic, successful and unlawful boycott actually appears. It is not in Judge Getzendanner 1987 opinion, and the misattribution is the most common error in the literature.
  • The limit, twice stated. Both courts declined to decide whether chiropractic is scientific, and the trial record showed that the controlled study the AMA House of Delegates itself called for in 1980 had never been done. Certiorari was denied on November 26, 1990 (498 U.S. 982), fourteen years after the complaint was filed.

Questions people ask

Did a court rule that chiropractic is scientific?

No. Judge Getzendanner wrote that her finding was not and should not be construed as a judicial endorsement of chiropractic, and she declined to pronounce chiropractic valid or invalid on anecdotal evidence. In 1990 the Seventh Circuit said that neither the district court nor the appellate court was equipped to determine whether chiropractic is scientific. The ruling concerned an illegal boycott under Section 1 of the Sherman Act.

Who actually wrote the line about a lengthy, systematic, successful and unlawful boycott?

The Seventh Circuit, in Wilk v. American Medical Association, 895 F.2d 352, decided February 7, 1990. The opinion was written by Judge Daniel Manion. The line is routinely credited to Judge Susan Getzendanner and dated to 1987. It does not appear in her opinion at 671 F. Supp. 1465.

Did the AMA pay damages to the chiropractors?

Not in this case. The plaintiffs waived their damages claim shortly before the 1987 retrial and asked only for an injunction under Section 16 of the Clayton Act. The American College of Radiology and the American College of Surgeons each paid $200,000 in settlements reached in the final days before the injunction issued. The radiologists directed their payment toward the plaintiffs legal costs.

Were all the defendants found liable?

No. The court found that three other bodies knowingly joined the conspiracy: the American College of Surgeons, the American College of Radiology, and the American Academy of Orthopedic Surgeons. Injunctive relief issued only against the AMA, ACS and ACR. The Joint Commission on Accreditation of Hospitals, the American College of Physicians, AAOS and Dr. James H. Sammons were dismissed. The Section 2 monopolization claim was dismissed with them.

How does the Unified Model of Tone read Wilk v. AMA?

The 1987 ruling ended the conduct without touching the belief that produced it, which was that only one profession could be correct about the body. The Unified Model of Tone holds that the professions are dialects describing a single phenomenon. When methods built on incompatible theories produce the same arc of recovery, the most parsimonious explanation is that they act on one underlying system. That system is tone. The case removed the ethics rule. The model supplies the shared language.
