MEMORANDUM OPINION AND ORDER GETZENDANNER, District Judge: This antitrust case is on remand for a new trial from the Court of Appeals, Wilk v. AMA, 719 F.2d 207 (7th Cir.1983) (“Wilk”). On May 4, 1987 the case was reassigned to me under Local Rule 2.30e for the purpose of conducting the trial. The trial was conducted during May and June of 1987. The record consists of 3,624 pages of transcript, approximately 1,265 exhibits, and excerpts from 73 depositions. On August 27, 1987, the Court issued a memorandum opinion containing written findings of fact and conclusions of law under Rule 52 of the Fed.R.Civ.P. Thereafter, two of the defendants, the American College of Surgeons and the American College of Radiology settled the case with the plaintiffs and I granted motions to amend the memorandum opinion of August 27th. In the present opinion I have made those changes, plus additional editorial changes, and have included citations to the record supplied, at my request, by plaintiff’s counsel but checked by me. I. The First Trial and the Wilk Decision The plaintiffs, Chester A. Wilk, James W. Bryden, Patricia B. Arthur, and Michael D. Pedigo, are licensed chiropractors. In a complaint filed in 1976, plaintiffs charged the defendants with violating Sections 1 and 2 of the Sherman Act, 15 U.S.C. Sections 1 and 2. Section 1 of the Sherman Act declares illegal every contract, combination or conspiracy in restraint of trade or commerce. Section 2 prescribes penalties for every person who shall monopolize, or attempt to monopolize, or combine or conspire with any other person or persons, to monopolize any part of the trade or commerce. The original defendants were the American Medical Association (“AMA”), the American Hospital Association (“AHA”), the American College of Surgeons (“ACS”), the Joint Commission on Accreditation of Hospitals (“JCAH”), the American College of Physicians (“ACP”), the American College of Radiology (“ACR”), the American Academy of Ortho-paedic Surgeons (“AAOS”), American Osteopathic Association (“AOS”), American Academy of Physical Medicine and Rehabilitation (“AAPMR”), Illinois State Medical Society (“ISMS”), Chicago Medical Society (“CMS”), The Medical Society of Cook County (“MSCC”), H. Doyl Taylor, Dr. Joseph A. Sabatier, Jr., M.D., Dr. H. Thomas Ballantine, M.D., and James H. Sammons, M.D. A number of the original defendants settled the case and have been dismissed, and all of the original individual defendants except Dr. Sammons obtained summary judgment prior to the retrial of this case. Thus, the defendants which remain in the case are the AMA, JCAH and AAOS. At the first trial, the plaintiffs’ principal claim was that the defendants engaged in a conspiracy to eliminate the chiropractic profession by refusing to deal with the plaintiffs and other chiropractors. Plaintiffs claimed that the boycott was accomplished through the use of Principle 3 of the AMA’s Principles of Medical Ethics (“AMA’s Principles”) which prohibited medical physicians from associating professionally with unscientific practitioners. Principle 3 provided as follows: 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. It was the plaintiffs’ contention that the AMA used Principle 3 to achieve a boycott of chiropractors by first calling chiropractors “unscientific practitioners,” and then advising AMA members and other medical societies that it was unethical for medical physicians to associate with chiropractors. The other defendants, plaintiffs claimed, joined the boycott and the result was a conspiracy in restraint of trade in violation of Section 1 of the Sherman Act. The jury returned a verdict for the defendants and against the plaintiffs. That judgment was reversed on appeal and the case was remanded. The Wilk Court clarified the principal legal issues in the case. The Court held that the legality of the defendants’ conduct under Section 1 must be adjudged under the rule of reason articulated in Chicago Board of Trade v. United States, 246 U.S. 231, 238, 38 S.Ct. 242, 244, 62 L.Ed. 683 (1918). The Court rejected the plaintiffs’ argument that the defendants’ conduct was a per se violation of Section 1, holding that “a canon of medical ethics purporting, surely not frivolously, to address the importance of scientific method gives rise to questions of sufficient delicacy and novelty at least to escape per se treatment.” 719 F.2d at 222. Under the rule of reason, the inquiry mandated is whether the challenged agreement is one that promotes competition or one that suppresses competition. National Society of Professional Engineers v. United States, 435 U.S. 679, 691, 98 S.Ct. 1355, 1365, 55 L.Ed.2d 637 (1978). The Court also considered whether proof of coercive enforcement of Principle 3 or of the purported agreement among the defendants was necessary to satisfy the Section 1 agreement criterion. Relying on Goldfarb v. Virginia State Bar, 421 U.S. 773 at 791, n. 21, 95 S.Ct. 2004, 2015 n. 21, 44 L.Ed.2d 572 (1975), the Court noted that even without a threat of professional discipline, the mere existence of ethical opinions of professional associations constitutes substantial reason to adhere to the standards because professionals would comply in order to assure that they did not discredit themselves by departing from professional norms. Thus, the Wilk Court held: ... even without coercive enforcement, a court may find that members of an association promulgating guidelines sanctioning conduct in violation of Sec. 1 participated in an agreement to engage in an illegal refusal to deal. 719 F.2d at 230. Next, the Court held that if the plaintiffs met their burden of showing that the effect of Principle 3 and the implementing conduct had been to restrict competition rather than to promote it, the defendants could then come forward to show: (1) that they genuinely entertained a concern for what they perceive as scientific method in the care of each person with whom they have entered into a doctor-patient relationship; (2) that this concern is objectively reasonable; (3) that this concern has been the dominant motivating factor in defendants’ promulgation of Principle 3 and in the conduct intended to implement it; and (4) that this concern for scientific method in patient care could not have been adequately satisfied in a manner less restrictive of competition. 719 F.2d at 227. This was called the “patient care defense.” Finally, with respect to the plaintiffs’ Section 2 claim, the Court of Appeals noted that it was not separately argued on appeal, and the Court declined to separately discuss it. Shortly before the scheduled trial before this court, the plaintiffs waived their claim for damages and sought only injunctive relief. This turned the case from a jury to a bench trial, and it shifted the focus of the case from the past to the present in order to determine whether the plaintiffs were entitled to injunctive relief under Section 16 of the Clayton Act. II. Summary of This Court’s Rulings In view of the length of this opinion, I shall summarize my principal findings. The AMA and its officials, including Dr. Sammons, instituted a boycott of chiropractors in the mid-1960s by informing AMA members that chiropractors were unscientific practitioners and that it was unethical for a medical physician to associate with chiropractors. The purpose of the boycott was to contain and eliminate the chiropractic profession. This conduct constituted a conspiracy among the AMA and its members and an unreasonable restraint of trade in violation of Section 1 of the Sherman Act. The AMA sought to spread the boycott to other medical societies. Other groups agreed to participate in the boycott by agreeing to induce their members to forego any form of professional, research, or educational association with chiropractors. The defendants which knowingly joined in the conspiracy were ACR (which has now been dismissed from the case) and AAOS. None of the defendants established the patient care defense. The plaintiffs are entitled to injunctive relief against the AMA, but not against AAOS or Dr. Sammons. The actions of the other defendants, JCAH and ACP, were taken independently of the AMA boycott and these defendants did not join the conspiracy. Accordingly, defendants JCAH, ACP, AAOS and Dr. Sammons are dismissed. The plaintiffs’ Section 2 claim was limited to the defendants’ alleged conspiracy to monopolize the hospital health care market through restrictive hospital accreditation standards promulgated by JCAH. In view of the court’s finding that JCAH did not join the conspiracy, the Section 2 claim is dismissed. III. New Zealand Report During trial I reserved ruling on an important evidentiary ruling, the admissibility of a report summarizing the findings of a task force appointed by the New Zealand government to study chiropractic in that nation, “Chiropractic in New Zealand: Report of the Commission of Inquiry” (“the New Zealand Report”). (PX 1829.) The New Zealand Report was heavily relied upon by the plaintiffs to show that chiropractic was a valid health care profession. The defendants opposed introduction of the report, and the parties have now briefed the issue. The Report was published in 1979 after nearly two years of investigation including 78 days of public hearings, 15 days of closed sessions, and visits to medical and chiropractic establishments both in New Zealand and other English-speaking countries. The plaintiffs assert that these acts entitle the Report to admission as evidence both for the truth of the matters asserted and for the purpose of showing the information available on chiropractic as of 1979. With one narrow exception, I disagree. Rule 803(8) of the Federal Rules Evidence, which is an exception to the hearsay rule embodied in Rule 802, makes admissible: Records, reports, statements, or data compilations, in any form, of public offices or agencies, setting forth ... in civil actions ... factual findings resulting from an investigation made pursuant to authority granted by law, unless the sources of information or other circumstances indicate lack of trustworthiness. The burden of proving untrustworthiness lies with those opposing admission. As explained in the advisory committee notes, “the rule ... assumes admissibility in the first instance but with ample provision for escape if sufficient negative factors are present.” Among these factors are the untimeliness of the inquiry, the lack of special skill or experience on the part of the investigating officials, procedural defects in the conduct of the investigation (such as failure to hold hearings), and/or the bias or motivation problems of the investigators. Other factors, both positive and negative, may, of course, also be considered. With these considerations in mind, the defendants assert that the New Zealand Report is fundamentally untrustworthy primarily because its conclusions are based upon otherwise inadmissible, unreliable evidence collected and evaluated by persons with no particular skill or background to make assessments respecting the safety or efficacy of health care practices. Defendants particularly object to the New Zealand Commission’s acceptance, at “face value,” of the testimonial accounts of patients’ experiences with chiropractors. The Commission found that such “evidence is not deci-' sive, but it is compelling.” Defendants’ view of the scientifically questionable basis of the New Zealand Report’s conclusions is supported by a review of the Report prepared by the United States Congress’ Office of Technology Assessment (“the OTA review”). (Exhibit A to Memorandum of Defendant ACR in Opposition to Admission of New Zealand Report.) That review questions the applicability of the New Zealand findings to the United States and finds “serious problems” in the Report’s treatment of safety and efficacy issues. Although the plaintiffs have suggested that the OTA review may be biased because it was prepared by a doctor of medicine, the court disregards these conclusory allegations. The OTA review itself is balanced and well-reasoned in its assessment of the New Zealand Report. Its primary criticism of the Report is not that its conclusions are wrong, but that they are not based upon well-designed, controlled clinical trials. Regarding the efficacy of chiropractic, the New Zealand Commission considered only five randomized trials. Of these, only two involved chiropractic services — each of which contained significant design flaws. The OTA review concluded: “There is a strong hint that spinal manipulation has efficacy in the immediate relief of back pain and other kinds of pain that goes beyond placebo effect. However, this can only be considered suggestive without further research.” (Id. at 6.) With respect to the question of chiropractic safety, the OTA review — after disparaging as “not evidence” anecdotal accounts in the medical literature purporting to show chiropractic is unsafe — stated it was unable to find any well-designed study. It concluded, consistent with this finding, that the New Zealand Report’s review of the safety issue was “unsatisfactory.” (Id. at 6.) In light of this thorough and well-considered appraisal of the New Zealand Report, with which I agree, I do not find the Report’s conclusions trustworthy. The request for admission for the purposes of showing the truth of the matter asserted is therefore denied. The plaintiffs urge, alternatively, that the New Zealand Report should be admitted to show first notice to the defendants that chiropractic was not quackery, and second that any belief that chiropractic was quackery could not be objectively reasonable. To the extent that the Report is offered solely to show information available on chiropractic in the latter half of 1979, the request to admit is unobjectionable. It is not, however, especially probative. The Report was not written until three years after the commencement of this lawsuit; its only possible relevance is with respect to plaintiffs' continuing violation point. The Report therefore may come in to show that the defendants may have suspected that their public position on chiropractic was untenable. It may not come in to show that that public stand was objectively unreasonable. To hold otherwise would negate my ruling on admissibility for the truth of the matter asserted. As the defendants correctly note, there is no basis upon which to infer that the defendants’ belief was not reasonable absent reliance on the truth of the Report itself. I hold, accordingly, that the New Zealand Report may be admitted, but only for the limited purpose stated. IY. Liability of the Defendants A. American Medical Association (“AMA”) and Dr. Sammons 1. Boycott Activities In the early 1960s the AMA became concerned that medical physicians were cooperating with chiropractors. (PX 550A.) In 1963, the AMA hired as its general counsel the author of the Iowa Medical Society’s plan to contain chiropractic in Iowa. (Throckmorton Dep.) As early as September 1963, the AMA’s objective was the complete elimination of the chiropractic profession. (PX 173.) In November of 1963, the AMA authorized the formation of the Committee on Quackery under the AMA’s Department of Investigation. (PX 555-59.) In 1964, the Committee’s primary goal was to contain and eliminate chiropractic. (PX 464, 727; Stevens Tr. 2104, 2117, 2122, 2162, 2170, 2185.) Throughout the 1960s and early 1970s, H. Doyl Taylor, the chairman of the Department of Investigation, repeatedly described the Committee’s prime mission to be the containment and elimination of chiropractic as a recognized health care service. (PX 464, 466, 188.) I found his video deposition denials, and his explanation that at all times he and the Committee only meant to eliminate chiropractic as a health hazard, incredible and unworthy of belief. Mr. Taylor believed that chiropractic was based on a “single cause — single cure” theory of disease and that given this baseless foundation, the entire profession should be swept away. The Committee worked aggressively to achieve its goals in several areas. It conducted nationwide conferences on chiropractic (PX 565, 742, 1177); prepared and distributed numerous publications critical of chiropractic (e.g., Holman Dep.); assisted others in the preparation and distribution of anti-chiropractic literature (e.g., PX 251, 439); regularly communicated with medical boards and associations, warning that professional association between medical physicians and chiropractors was unethical (e.g., PX 466, 498, 550, 550A, 1288, 12C, 7296, 1705); and attempted to discourage colleges, universities, and faculty members from cooperating with chiropractic schools (e.g., PX 532, 456, 1519, 790; Fine-berg Dep.; Tr. 2112-15). In 1966, the AMA adopted an anti-chiropractic resolution. (PX 464.) This resolution, recommended by the AMA Board of Trustees and adopted by the House of Delegates, called chiropractic an unscientific cult. (PX 464, 500.) This label implicitly invoked Principle 3 of the AMA’s Principles which made it unethical for a physician to associate with an unscientific practitioner. (E.g., PX 56, 156A, 499A, 741, 745, 746.) In 1967, the AMA Judicial Council issued an opinion under Principle 3 specifically holding that it was unethical for a physician to associate professionally with chiropractors. (Tr. 2939.) “Associating professionally” would include making referrals of patients to chiropractors, accepting referrals from chiropractors, providing diagnostic, laboratory, or radiology services for chiropractors, teaching chiropractors, or practicing together in any form. This opinion was published in the 1969 Opinions and Reports of the Judicial Council of the AMA (“1969 Opinions,” PX 505) which was widely circulated to members of the AMA. (Holman Dep.) The opinion on chiropractic was also sent by the AMA to 56 medical specialty boards and associations. (PX 550, 550A.) The AMA and the Committee on Quackery used the anti-chiropractic policy statement as a tool — what the Committee called a “necessary tool” — to spread the boycott to other medical groups. The Committee’s efforts were successful. (PX 464.) Other groups, including some of the defendants, specifically adopted or approved the policy statement on the ethical prohibition against association with chiropractors. (PX 464, 478B, 1166, 120.) In 1971, the Committee made a report (PX 464) of its activities to the AMA Board of Trustees and described the policy statement as follows: This was the necessary tool with which your Committee has been able to widen the base of its chiropractic campaign. With it, other health-related groups were asked and did adopt the AMA policy statement or individually-phrased versions of it. These, in turn led to even wider acceptance of the AMA position. * * * * * # The hoped-for effect of this widened base of support was and is to minimize the chiropractic argument that the campaign is simply one of economics, dictated and manipulated by the AMA. The memorandum further stated: The Committee has not submitted such a report [earlier] because it believes that to make public some of its activities would have been and continues to be unwise. Thus this report is intended only for the information of the Board of Trustees. Principle 3 was widely viewed as proscribing association with chiropractors. The three defendants who issued the Status Report on Chiropractic Lawsuits in 1978 acknowledged in that Report that Principle 3 proscribed association with chiropractors. (PX 1069.) Any reasonable medical physician who read Principle 3 and either the AMA policy statement or any AMA reference to chiropractors as unscientific practitioners, would conclude that it was unethical for medical physicians to associate with a chiropractor. (E.g., PX 499A, 1477B.) In 1973, the AMA drafted Standard X, which incorporated the unscientific practitioners ethics bar into the JCAH hospital accrediting standards. (PX 2266, 72.) The AMA urged JCAH to adopt Standard X, and JCAH complied. (Id.) Keeping chiropractors out of hospitals was one of the goals of the boycott. (PX 9D, 9E, 9F, 9G, 12B, 12C, 18.) When chiropractic was included under Medicare in 1973, the AMA became concerned that this would open the way for chiropractors to be on hospital staffs. (E.g., PX 651, 700.) Doyl Taylor caused the Office of General Counsel of the AMA to publish an article entitled “The Right and Duty of Hospitals to Exclude Chiropractors” in the Journal of the American Medical Association. (PX 464.) This was intended to offer advice to hospital trustees across the country. (PX 716.) It also told every hospital attorney that JCAH accreditation might be lost if hospitals dealt with chiropractors. (E.g., PX 12B, 12C.) The Committee on Quackery disbanded in December of 1974. By this time, chiropractic had achieved licensing in all fifty states, chiropractic services had become reimbursable through Medicare, Medicaid, and virtually every private health insurance plan, and the chiropractic educational system had been given official sanction by the United States Office of Education. Nevertheless, the Committee pronounced itself a success. (Taylor Vid. Dep; PX 464.) The AMA believed that chiropractic would have achieved greater growth if it had not been for the Committee’s activities. (PX 253.) In May of 1975 the AMA Department of Investigation was disbanded and Doyl Taylor left the employ of the AMA. (PX 7292; Taylor Vid. Dep.) This lawsuit was filed in 1976. In that year, the Judicial Council suspended distribution of the 1971 Opinions which contained the anti-chiropractic policy. (Tr. 2939.) Later that year the AMA Judicial Council adopted Opinion 3.50 and in March of 1977 Opinions 3.60, 3.70, and 3.71 were adopted. (Tr. 2940; DX 21231.) Under these opinions, a medical physician could refer a patient to a “limited licensed practitioner” for diagnostic or other health care services. Although there was no express reference to chiropractors, chiropractors would fall within the definition of “limited licensed practitioners.” Next, a medical physician could choose to accept or decline patients sent to her or him by a licensed practitioner or by a layman. Finally, a medical physician could engage in any teaching permitted by law for which she or he is qualified. However, the relaxation of the right to refer patients was not without qualification. Opinion 3.60 specifically required that a medical physician should not refer a patient unless she or he is confident that the services provided on referral will be performed in accordance with accepted scientific standards. In addition, Opinion 3.01 provided that it is “wrong to engage in or aid and abet any treatment which has no scientific basis and is dangerous.” Distribution of the revised opinions began in May of 1977. (Tr. 2941.) Principle 3 was still in effect. In July of 1979, the AMA House of Delegates adopted Report UU. Report UU (Tr. 2941; PX 7248) was the AMA’s new policy statement on chiropractic. It was a very begrudging change of position. Although it is now hailed by the AMA lawyers and Dr. Alan R. Nelson (Tr. 2028-33), present Chairman of AMA’s Board of Trustees, as a recognition by the AMA of the growth and development of chiropractic as a valid health care service, the Report does not convey that change of heart. First, Report UU states that the AMA knows of no scientific evidence to support spinal manipulation and adjustment as appropriate treatment for such diseases as cancer, diabetes, and infections. It does not declare support for that which the AMA seemingly now approves — chiropractic manipulation for musculoskeletal problems. Next the Report condemns the single cause of disease theory and states that “chiropractors disagree on the extent to which they accept or reject traditional chiropractic doctrine.” The Report does not state that the two major chiropractic associations had rejected the doctrine in 1969. (PX 245.) But the Report continues: Describing chiropractic as an “unscientific cult” does not, however, necessarily mean that everything a chiropractor may do when acting within the scope of his or her license granted by the state is without therapeutic value, nor does it mean that all chiropractors should be equated with cultists. It is better to call attention to the limitations of chiropractic in the treatment of particular ailments than to label chiropractic an “unscientific cult.” The Report then reaffirms that a physician should at all times practice a method of healing founded on a scientific basis. This again directly tied into Principle 3 which prohibited association with unscientific practitioners. Although the Report ends by stating that a medical physician may refer a patient to a limited licensed practitioner permitted by law to furnish such services, there is no particular reference to chiropractors. Report UU was obviously written by lawyers in an effort to bring the AMA into compliance with the antitrust laws, and not a bold change of position designed to reverse the attitudes of the AMA members formed, at least in part, by the then eleven-year old boycott. In December of 1978, the AMA House of Delegates adopted Resolution 14 which provided that medical physicians “continue to exercise the duty to expose unscientific practices and practitioners while supporting and protecting the freedom of individuals to choose among physicians, other licensed practitioners or religious healers as part of the American tradition.” (PX 7248.) It is hard to tell the purpose of this resolution, other than to suggest a similarity between chiropractors and Elmer Gantry, but it once again keyed into Principle 3 which condemned association with unscientific practitioners. In 1980 the AMA adopted a completely revised version of the principles of medical ethics. .(Tr. 2947-48; DX 21233.) Principle 3 finally was eliminated. The new principles provided that a medical physician “shall be free to choose whom to serve, with whom to associate, and the environment in which to provide medical services.” (PX 7249.) The revised principles theoretically do allow association with chiropractors but there is no explicit reference to chiropractors in the new code. The revised code received a fair amount of publicity in the medical and private press in 1980. (DX 21209, 21211-12, 21221.) The revision was interpreted as changing the AMA’s position on chiropractic in response to various pressures, including the legal climate. And yet, two years later, when Dr. Daniel T. Cloud, who was then finishing his term as president of the AMA, was asked in a formal interview whether the 1980 ethics code changed the position of doctors with regard to chiropractors— “Was there a change? — he stated, “No.” (PX 7125.) This fairly bizarre answer (considering the nature of the publicity the ethics revision received) today is explained by the AMA’s lawyers as a technically accurate answer since, they assert, the change in position was accomplished in 1977 and 1979. Yet today the AMA relies on the revision of the ethical standards in 1980 as part of its change in position on chiropractic. The lawyers’ argument is not persuasive. In 1982 the president of the AMA appears to be announcing that the AMA has not changed its position on chiropractic. The AMA settled three chiropractic lawsuits in 1978, 1980 and 1986 by stipulating and agreeing that under its current opinions of the Judicial Council a medical physician may, without fear of discipline or sanction by the AMA, refer a patient to a duly licensed chiropractor when he believes that referral may benefit the patient. The AMA confirmed that a physician may teach at a chiropractic college or seminar and that a physician may choose to accept or decline patients sent to him by a chiropractor. The only settlement entered into prior to the end of the boycott was in 1978, and that settlement did not effectuate a termination of the boycott since Principle 3 was still in effect. In 1983 the AMA participated in the revision of the JCAH accreditation standards for hospitals. The revision process started in 1982 with recommendations from the JCAH staff and the JCAH Standard-Survey Procedures Committee that each hospital, through its governing body, be permitted to decide for itself, under applicable state law, which licensed health care providers would be allowed hospital privileges and membership on the medical staff. (Tr. 1775.) The AMA initially supported this approach but it was severely criticized by its members and other medical societies which wanted to ensure medical and osteopathic physician control of the medical staff and patient care in hospitals. (E.g., PX 7101-02, 7146, 7161-68, 7192, 7317.) As a result of this criticism, the AMA changed its position and supported revisions which would ensure such control. (PX 7102, 7109.) In February of 1983, the AMA voted to recommend revised standards that would require the medical staff of each hospital to have an “executive committee,” the majority of which had to be medical or osteopathic physicians. (PX 7102.) The executive committee would make recommendations to the hospital’s governing body for its approval of credentialing, membership on the medical staff, hospital privileges delineations, and structure of the medical staff. Any dispute between the medical staff and the governing body of the hospital would have to be resolved jointly by them. (PX 7142-48, 7150-54.) In late 1983, JCAH adopted the new standards which included the mandatory, medical physician dominated executive committee concept. (Tr. 1771-74.) The plaintiffs rely heavily on the 1983 accreditation standards to show that the conspiracy was ongoing. This issue is discussed generally in the section of this opinion dealing with JCAH, and, in short, I have rejected the argument. What is noteworthy with respect to the AMA, however, is that although it believed that the standards originally proposed by the JCAH Standards-Survey Procedures Committee were more in tune with the existing antitrust “legal climate,” it was unable to sustain its position when faced with substantial criticism of its members and other medical groups. (PX 7153, 7103, 7120, 7133, 7159, 7192.) Through the date of the trial, the AMA continued to respond to requests for information on chiropractic which it received from AMA members and others by sending out anti-chiropractic literature. (PX 7230, 7245-47, 7219-20, 7224-25, 7287, 7210, 7227, 7234-36, 7238-39.) The old boycott language has been eliminated, but the AMA has not had anything positive to say about chiropractic. It was not until midway through the trial of this case that the AMA announced that chiropractic has improved and that at least some forms of chiropractic treatment and joint adjustments are scientific. (Tr. 1214-17, 1222, 1249-56, 1259-60, 1975-76, 2029-30, 2984.) The membership has never been informed of this position. The plaintiffs argue that the AMA boycott began in 1966 and continued until 1983 when the JCAH accreditation standards were revised. The AMA argues that Report UU and the 1977 opinions constitut-. ed a change in the AMA’s policy on chiropractors and that any conspiracy ended in 1977 or before. I reject both positions. The discussion of the 1983 revision of the JCAH standards is continued in the section of this opinion dealing with JCAH. Regarding the AHA’s argument, Report UU and the 1977 opinions were clearly inadequate to end the boycott, and probably deliberately so. This is well demonstrated by the American College of Physicians’ analysis of the 1977 revisions of the opinions. (PX 1440.) In a 1978 report to its members, the ACP stated: In 1977, as noted above, a revision of the Judicial Council interpretations of the AMA Principles of Medical Ethics appeared. The explicit language of 1966 was absent; there was no reference to chiropractic per se. In many places, the language used was unclear and ambiguous. Paragraph 1, Section 3.50, of the 1977 Judicial Council Opinions and Reports does, however, remain forthright: “A physician should not use unscientific methods of treatment, nor should he voluntarily associate professionally with anyone who does. It is wrong to engage in, or to aid and abet in treatment which has no scientific basis and is dangerous, is calculated to deceive the patient by giving him false hope, or which may cause the patient to delay in seeking proper care until his condition becomes irreversible.” This interpretation supports the court’s view that the 1977 opinions were ambiguous and that the use of the key phrase “unscientific methods” continued to signal the existence of the boycott. I also find that the settlement agreements in other chiropractic litigation that occurred prior to 1980 did not end the boycott since Principle 3 was still in effect and the AMA had never publicly stated that its policy on chiropractic (calling chiropractic “unscientific”) was wrong. I conclude that the AMA and its members engaged in a group boycott or conspiracy against chiropractors from 1966 to 1980, when Principle 3 was finally eliminated. 2. Unreasonable Restraint of Trade The next question is whether the boycott or conspiracy constituted an unreasonable restraint of trade under Section 1 of the Sherman Act. To answer this question, I have undertaken a rule of reason analysis. The relevant market was the provision of health care services to the American public on a nationwide basis, particularly for the treatment of musculoskeletal problems. As noted by the Court of Appeals, some medical physicians (such as orthopedic surgeons, internists, and general practitioners) are in direct competition with chiropractors in this market. Medical physicians and chiropractors are interchangeable for the same purposes. (Tr. 423-26, 429-30, 433-34, 1259, 1953, 2108, 7140, 1449.) Consumers seek both medical physicians and chiropractors for the same complaints, principally back pain and other neuromusculoskeletal problems, and both groups render services for the treatment of those complaints. (Tr. 1104-36; PX 7247, 1055, 1529 at 46, 7208.) Competition between medical physicians and chiropractors was recognized by Dr. Joseph A. Sabatier, a member of the Committee on Quackery and a former defendant in this case, as early as 1964. At one point, Dr. Sabatier stated, “it would be well to get across that the doctor of chiropractic is stealing [the young medical physician's] money.” (PX 322; see also, PX 172 at 8, 241.) The AMA’s intent is clearly relevant to the rule of reason analysis. The boycott was intended to contain and eliminate the entire profession of chiropractic. (Taylor Vid. Dep.; PX 464; Tr. 2104, 2117, 2122, 2162, 2170, 2185.) Whether or not the elimination of competition per se was consciously intended, that was the natural result of an intent to destroy a competitor. The AMA’s market power is also relevant. Members of the AMA constitute a substantial force in the provision of health care services in the United States. (Tr. 416.) They constitute a majority of medical physicians (PX 7325, 7327-28; Tr. 415-16), and a much greater portion of fees paid to medical physicians in the United States is paid to AMA members. (Tr. 416.) Given the substantial market power of AMA members and the specific intent of the AMA, a substantial adverse effect on competition is evident. Despite the fact that the number of chiropractic schools, the number of chiropractors, and the number of chiropractic schools, the number of chiropractors, and the number of patient visits to chiropractors grew during the boycott, I accept the Committee on Quackery’s admissions that the boycott was successful. (Taylor Vid.Dep.; PX 464.) These admissions were not mere puffery. The success of the boycott is shown in part by the adverse reaction of various medical societies to the AMA’s modification of its anti-chiropractic policy in 1977 and the AMA’s settlement of some chiropractic lawsuits in the late ’70s and early ’80s. (E.g., PX 1069.) Many medical physicians individually criticized the AMA for ameliorating its policy. This shows substantial support for the boycott. (Id.) It was also clear to me from the testimony, particularly of the older medical physicians, that medical physicians acted in conformity with Principle 3. (E.g., PX 1498A, 1467, 1477B, 1519A, 14A; Stronach Dep.; Bender Dep.) A principle of medical ethics is inherently a forceful mandater of conduct. No honest professional wants to risk the stigma of being labeled unethical. As the Court of Appeals noted, the fact that the AMA never sanctioned or disciplined a member for violation of Principle 3 is not controlling. Enforcement was not necessary to obtain compliance with the boycott. The anti-competitive effects of the boycott were generally conceded by the defendants’ expert, William J. Lynk of Lexe-con Inc. (Tr. 1290-1346, 1361-1555.) Some of the anti-competitive effects acknowledged by Mr. Lynk include »the following: it is anti-competitive and it raises costs to interfere with the consumer’s free choice to take the product of his liking; it is anti-competitive to prevent medical physicians from referring patients to a chiropractor; (Lynk 1427-28) it is anti-competitive to impose higher costs on chiropractors by forcing them to pay for their own x-ray equipment rather than obtaining x-rays from hospital radiology departments or radiologists in private practice; and it is anti-competitive to prevent chiropractors from improving their education in a professional setting by preventing medical physicians from teaching or lecturing to chiropractors. (Tr. 1409-22, 1424-31.) Mr. Lynk agreed that in an economic sense a boycott such as the one described by plaintiffs raises the costs of chiropractic services and creates inefficiencies and economic dislocations. Obviously, Mr. Lynk did not concede the existence of the boycott but agreed that these would be anti-competitive effects that would flow from such a boycott. I have also considered the fact that, as conceded by Mr. Lynk, there are substantial barriers to the entry of new chiropractors into the field, such as substantial education requirements. These barriers increase the likelihood that the boycott had a substantial adverse effect on competition. The Court of Appeals in Wilk, which reviewed substantially the same boycott evidence, concluded: Through such mechanisms, individual physicians were discouraged from cooperating with chiropractors in: patient treatment, because referrals were inhibited by defendants’ activities; research; and educational activities, such as sharing clinical experience and research results. Chiropractors were denied access to the hospital facilities they considered necessary to practice their professions. Medical doctors were discouraged from aiding chiropractors in interpreting electrocardiograms. Requests by individual plaintiffs to use laboratory and X-ray facilities were not granted; requests for hospital in-patient privileges were similarly denied. Referrals from medical doctors were reduced. Public demand for chiropractic services was negatively affected. 719 F.2d at 214. The defendants argue that all of this evidence is not enough — that the plaintiffs must specifically prove an impact on price and output. The cases do not support that position. As Professor Areeda recently noted in his article “The Rule of Reason — a Catechism on Competition,” 55 Antitrust Law Journal, 571 (1986), the Supreme Court has held that the purpose of the inquiry into market definition and market power is to determine whether an arrangement has the potential for genuine adverse effects on competition. If there is actual proof of adverse effects, then the plaintiffs need not prove market definition and market power. The Supreme Court in Federal Trade Commission v. Indiana Federation of Dentists, 476 U.S. 447, 106 S.Ct. 2009, 2019, 90 L.Ed.2d 445 (1986), stated that “the inquiry into market power is but a surrogate for detrimental effects.” The AMA relies on Mr. Lynk’s conclusion that the boycott had pro-competitive effects that would have outweighed the anti-competitive effects. (Tr. 1409.) Mr. Lynk’s theory is that the boycott constituted nonverbal communication which informed consumers about the differences between medical physicians and chiropractors, and that this had a pro-competitive effect. (Tr. 1411-12.) I reject this opinion as speculative. (Tr. 1434-43.) Mr. Lynk neither conducted nor read any studies regarding the efficacy of such nonverbal communications. Id. He neither conducted nor read any surveys of consumer opinion to determine whether consumers were confused about the differences between medical physicians and chiropractors. (Id.) I saw no evidence of any such confusion during the trial. Mr. Lynk’s opinion does not accord with common sense. A nationwide conspiracy intended by its participants to contain and eliminate a licensed profession cannot be justified on the basis of Mr. Lynk’s personal opinion that it was pro-competitive, nonverbal communication to consumers. 3. Antitrust Injury Having determined that the effect of Principle 3 and the implementing conduct has been to unreasonably restrict competition rather than to promote it, I now consider whether the plaintiffs have shown injury of the kind the antitrust laws were designed to prevent. The plaintiffs principally rely on the testimony of Dr. Miron Stano, their economic expert. Dr. Stano compared the income of chiropractors, podiatrists, and optometrists over the relevant period of time and concluded that the income of chiropractors was lower than that of the other, comparable limited licensed practitioners. (Tr. 458.) He viewed this as consistent with the boycott theory. He also noted a jump in chiropractors’ income during the period 1978 to 1980 and he concluded that the jump was consistent with the acknowledged lessening of the boycott by the AMA during that period. (Tr. 461.) The defendants’ economic expert, Mr. Lynk, faulted the data relied upon by Dr. Stano (Tr. 1309-20), but he agreed that if he were to compare chiropractors’ income to comparable groups, he would also include podiatrists and optometrists, as well as other groups, but he would seek further explanations for the differences between the groups’ incomes. (Tr. 1464-67.) Mr. Lynk further criticized the “jump” analysis done by Dr. Stano due to the fact that Dr. Stano relied on income projections from the Bureau of Labor Statistics (“BLS”). (Tr. 1310, 1322-23, 1500.) Defendants argued that BLS statistics are a poor source to begin with, and that reliance on such statistics further was not justified because in 1980 BLS began to note that it obtained its income projections for chiropractors from the American Chiropractors Association, thus signaling a change in the data collection methodology used by the BLS. This revelation caused the recalling of Dr. Sta-no, the introduction of a new defense expert, Mr. Robert Topel, a labor economist from the University of Chicago, and a new deposition of Dr. Stano. Mr. Topel’s testimony cast further doubt on the BLS data used by Dr. Stano. (Topel Tr. 3574-3589.) However, the cross examination of Mr. Lynk demonstrated to my satisfaction that the data used by Dr. Stano were reasonable. Several of the critical numbers had some independent verification. (Tr. 1525-30.) I have also considered Mr. Topel’s criticism but find that the data collection procedures used by the BLS during the relevant time remained consistent enough to be useful in this case. I do not rely on Dr. Stano’s evidence in isolation. I understand that the data are not the best that could be used for such studies, but the best data, suggested by Mr. Topel, do not exist. What lends support to Dr. Stano’s result is the very strong evidence of a pervasive, nationwide, effective conspiracy which by its very nature would have affected the demand curve for chiropractic services and adversely affected income of chiropractors. Again, defendants’ economist, Mr. Lynk, agreed that such a conspiracy would shift the demand curve for chiropractic services. (Tr. 1415-22.) The plaintiffs also established injury to reputation suffered by chiropractors. Both economic experts believed that injury to reputation would constitute an anti-competitive effect of the boycott. (Tr. 410-11, 1456-59.) See Weiss v. York Hospital, 745 F.2d 786, 806-07 (3rd Cir.1984), cert. denied, 470 U.S. 1060, 105 S.Ct. 1777, 84 L.Ed.2d 836 (1985) (policy denying staff privileges to osteopaths likely to injure their professional reputations). In addition to labeling all chiropractors as unscientific cultists and depriving chiropractors of association with medical physicians, injury to reputation was assured by the AMA’s name-calling practice. For example, in 1973, Dr. Sabatier, an AMA official, described chiropractors as rabid dogs and killers. (PX 1288.) Such statements were made in furtherance of the conspiracy and obviously injure reputations. 4. Rejection of Per Se Violation The Seventh Circuit has already held that Principle 3 escapes per se treatment because it involves a medical ethic which nonfrivolously addresses the importance of scientific method, a subject well within the natural ambit of a medical association. The plaintiffs argue that the Supreme Court’s decision in F.T.C. v. Indiana Federation of Dentists, 106 S.Ct. 2009 (1986), decided after Wilk, compels application of the per se analysis. I disagree. First, Indiana Dentists itself was decided under a rule of reason analysis. Although the Supreme Court rejected the dentists’ rationale that the withholding of x-rays in that case was justifiable as being in the best interests of patients, and specifically said that such a purported justification was legally and factually marred, the Court did not apply a per se rule. Indiana Dentists is quite like National Society of Professional Engineers v. United States, 435 U.S. 679, 98 S.Ct. 1355, 55 L.Ed.2d 637 (1978). In both cases the Supreme Court refused to allow professional competitors to deprive consumers of information they desired, and in both cases the court rejected the professionals’ purported consumer welfare justifications for the restraint. I believe the result in Indiana Dentists was based on the same rationale that decided Professional Engineers. I do not read Indiana Dentists as requiring a per se analysis. The plaintiffs also urge that Indiana Dentists eliminates the patient care defense created by the Seventh Circuit in Wilk. The Supreme Court did not address, the specific issue of whether patient care defense on the facts in this case would be allowed, and since Indiana Dentists is much more like Professional Engineers than this case, I believe I must follow Wilk. 5. Patient Care Defense I now consider whether the AMA has established the Wilk patient care defense. The first element is whether the AMA and its members genuinely entertained a concern for scientific method in the care of patients. I have some questions about the genuineness of the AMA’s concern for scientific method based on the fact that when the AMA adopted changes in its chiropractic policy between 1977 and 1980, it apparently did so without deciding whether chiropractic was scientific. That shows disregard for scientific method in patient care. Nevertheless, I conclude that the AMA has established this element. At the time it was attacking chiropractic as unscientific, it was attacking other unscientific methods of treatment of disease, for example the Krebiozen treatment of cancer. The existence of medical standards or guidelines against unscientific practice is common. Other medical societies have long had such prohibitions and the chiropractors themselves have a similar ethical guideline. (DX L31.) So I conclude that the AMA has established the first element of genuine concern. The next element is whether the concern for scientific method in patient care is objectively reasonable. In connection with this element of the patient care defense, the parties have devoted a substantial amount of effort in attempting to prove that chiropractic was either good or bad, efficacious or deleterious, quackery or science. At the time the Committee on Quackery was operating, there was a lot of material available to the Committee that supported its belief that all chiropractic was unscientific and deleterious. (Tr. 2063-90.) In fact, there was a substantial amount of evidence on which the Committee reasonably could conclude that chiropractic was based on the single cause of disease theory, despite some contrary evidence that the theory had been disavowed by modern practitioners. (Id.) There also was some evidence before the Committee that chiropractic was effective — more effective than the medical profession in treating certain kinds of problems such as workmen’s back injuries. (E.g., PX 241, 1476, 1471-72, 184, 192-94; Ballantine Dep. 137-39.) The Committee on Quackery was also aware that some medical physicians believed chiropractic to be effective and that chiropractors were better trained to deal with musculoskeletal problems than most medical physicians. (Id.; Tr. 2159-74.) The Committee did not follow up on any of these studies or opinions. (Id.) Basically the Committee members were doctors who, because of their firm belief that chiropractic had to be stopped and eliminated, volunteered for service on the committee. Dr. David B. Stevens, who testified during the trial, was one of these dedicated individuals who devoted a substantial amount of time to his committee work. (Tr. 2065.) But it was very clear that he and other committee members did not have minds open to pro-chiropractic arguments or evidence. (Tr. 2159-74.) The AMA acknowledges that, after the Committee on Quackery disbanded, chiropractic improved (and the AMA takes partial credit for it). For example, Mr. Carlson, one of the AMA’s trial attorneys, stated in final argument: Dr. Winterstein testified that chiropractic has changed. And it has changed. And we suggest that one reason that it changed was because of the criticism of its bizarre methods. Now, do you hear in this courtroom anything about one eause/one cure? Sure don’t. You hear about neuromusculo reasons, neuromusculo diagnosis, neuromusculo conditions. This is the new parlance. They have done away, for the most part, with the one cause/one cure. I understand there is one small element of chiropractic that still adheres to it. But it’s not the major element. ... And they have improved_ Chiropractic, I think is still changing. It began really changing when the accrediting arm of the ACA [American Chiropractic Association], as opposed to the ICA [International Chiropractic Association], was accepted, was recognized by the Department of Education as the sole accrediting body for chiropractic. And that occurred in ’73, ’74, ’75, something like that. And that’s really when chiropractic began to evolve. (Tr. 3132-33.) Most significantly, Dr. Alan R. Nelson, the current Chairman of the Board of Trustees of the AMA testified (at pp. 2029-30): My personal position, and I think that I can accurately reflect the position of the AMA in this, is that the fundamental theory of chiropractic as it was earlier portrayed was not supported by scientific evidence, first. Secondly, that the nature of services that are being delivered by chiropractors are now diverse and includes some forms of manipulation that do have a scientific basis. And, third, the responsibility for determining what is in the best interest of an individual patient rests with the individual practitioner and that there is nothing unethical about me asking a chiropractor to deliver a form of manipulative therapy that appears to me to have a scientific basis, and I think I’m accurately reflecting the testimony of Dr. Epps. Most defense witnesses agreed that some chiropractic treatment is therapeutic — although certainly no one involved in this case, including the plaintiffs, believes that chiropractic treatment should be used for the treatment of diseases such as cancer, diabetes, heart disease, high blood pressure, and infections. (E.g., Tr. 1214-17, 1222, 1249-56, 1259-60, 1975-76, 2029-30, 2984.) It is hard to pinpoint when the changes in chiropractic testified to by AMA witnesses occurred, but it is likely that they occurred while the boycott was still in effect. Thus the AMA’s own evidence suggests that at some point during the boycott there was no longer an objectively reasonable concern that would support a boycott of the entire chiropractic profession. The plaintiffs clearly want more from the court. They want a judicial pronouncement that chiropractic is a valid, efficacious, even scientific health care service. I believe that the answer to that question can only be provided by a well designed, controlled, scientific study such as the one urged by the United States Congress’ Office of Technology Assessment in its review of the New Zealand Report. In 1980, the AMA House of Delegates urged that such a study be done. No such study has ever been done. In the absence of such a study, the court is left to decide the issue on the basis of largely anecdotal evidence. I decline to pronounce chiropractic valid or invalid on anecdotal evidence. The plaintiffs, however, point out that the anecdotal evidence in the record favors chiropractors. The patients who testified were helped by chiropractors and not by medical physicians. (Tr. 1109-36.) Dr. Per Freitag, a medical physician who associates with chiropractors, has observed that patients in one hospital who receive chiropractic treatment are released sooner than patients in another hospital in which he is on staff which does not allow chiropractors. (Tr. 812.) Dr. John McMillan Men-nell, M.D. testified in favor of chiropractic. (Tr. 35-42.) Even the defendants’ economic witness, Mr. Lynk, assumed that chiropractors outperformed medical physicians in the treatment of certain conditions and he believed that was a reasonable assumption. (Tr. 1414.) The defendants have offered some evidence as to the unscientific nature of chiropractic. The study of how the five original named plaintiffs diagnosed and actually treated patients with common symptoms was particularly impressive. (Tr. 2208-319.) This study demonstrated that the plaintiffs do not use common methods in treating common symptoms and that the treatment of patients appears to be undertaken on an ad hoc rather than on a scientific basis. And there was evidence of the use of cranial adjustments to cure cerebral palsy and other equally alarming practices by some chiropractors. (Tr. 917.) I do not minimize the negative evidence. But most of the defense witnesses, surprisingly, appeared to be testifying for the plaintiffs. Taking into account all of the evidence, I conclude only that the AMA has failed to meet its burden on the issue of whether its concern for the scientific method in support of the boycott of the entire chiropractic profession was objectively reasonable throughout the entire period of the boycott. This finding is not and should not be construed as a judicial endorsement of chiropractic. The next element of the patient care defense is whether the AMA’s concern about scientific method has been the dominant motivating factor in the defendants’ promulgation of Principle 3 in the conduct undertaken and intended to implement Principle 3. The AMA has carried its burden on this issue. While there is some evidence that the Committee on Quackery and the AMA were motivated by economic concerns — there are too many references in the record to chiropractors as competitors to ignore — I am persuaded that the dominant factor was patient care and the AMA’s subjective belief that chiropractic was not in the best interests of patients. The final question is whether this concern for scientific method in patient care could have been adequately satisfied in a manner less restrictive of competition. It would be a difficult task to persuade a court that a boycott and conspiracy designed to contain and eliminate a profession that was licensed in all fifty states at the time the Committee on Quackery disbanded was the only way to satisfy the AMA’s concern for the use of scientific method in patient care. The AMA presented no evidence that a public education approach or any other less restrictive approach was beyond the ability or resources of the AMA or had been tried and failed. The AMA obviously was not successful in defeating the licensing of chiropractic on a state by state basis, but that failure does not mean that they had to resort to the highly restrictive means of the boycott. The AMA and other medical societies have managed to change America’s health-related conduct by what appears to be good public relations work and there has been no proof that a similar campaign would not have been at least as effective as the boycott in educating consumers about chiropractic and the AMA’s concern for scientific method. Based on these findings, I conclude that the AMA has failed to carry its burden of persuasion on the patient care defense. 6. Entitlement to an Injunction Section 16 of the Clayton Act gives private parties the right to seek injunctive relief for violation of the antitrust laws: Any person, firm, corporation, or association shall be entitled to sue for and have injunctive relief ... against threatened loss or damage by a violation of the antitrust laws ... when and under the same conditions and principles as injunc-tive relief against threatened conduct that will cause loss or damage is granted by courts of equity, under the rules governing such proceedings.... In accordance with well established Supreme Court decisions, all that is required to state a case for such relief is “a real threat of future violation or a contemporary violation of a nature likely to continue or recur.” United States v. Oregon State Medical Soc., 343 U.S. 326, 333, 72 S.Ct. 690, 695, 96 L.Ed. 978 (1952); Zenith Radio Corp. v. Hazeltine Research, Inc., 395 U.S. 100, 130, 89 S.Ct. 1562, 1580, 23 L.Ed.2d 129 (1969). Thus, although the statutory provision “invokes traditional principles of equity,” Zenith Radio at 130, 89 S.Ct. at 1580, an antitrust plaintiff need not meet all of the requirements for an injunction imposed by traditional equity jurisprudence. Commodity Futures Trading Comm. v. Hunt, 591 F.2d 1211, 1220 (7th Cir.1979). Any relief fashioned by the court the regulatory scheme and adequately serve the particularized needs of the case before the court. The trial court’s discretion must be exercised to effectuate the manifest objective of the specific legislation involved. Commodity Futures, 591 F.2d at 1220, quoting SEC v. Advance Capital Growth Corp., 470 F.2d 40, 53 (7th Cir.1972). In view of the strong public policies private antitrust plaintiffs tend to promote, the teaching of Commodity Futures is important to the court’s decision in this case. In determining the appropriateness of in-junctive relief, courts have typically scrutinized the prior conduct of the defendant. Voluntary cessation of allegedly illegal conduct is looked upon with extreme skepticism by courts but may be a factor in determining the appropriateness of injunctive relief “if the defendant can demonstrate that there is no reasonable expectation that the wrong will be repeated. The burden is a heavy one.” United States v. Realty Multi-List, Inc., 629 F.2d 1351, 1388 (5th Cir.1980), quoting United States v. W.T. Grant Co., 345 U.S. 629, 633, 73 S.Ct. 894, 897, 97 L.Ed. 1303 (1953). Where a violation has been founded on systematic wrongdoing, rather than on isolated occurrence or event, the Seventh Circui
