 | 
  
    | [14] | Evidence Code section 1157 provides that the records of a hospital 
      peer review committee are not "subject to discovery." We address here the 
      narrow issue whether an investigative subpoena issued by the Medical Board 
      of California as part of its inquiry into the conduct of a physician with 
      an apparent drug problem is "discovery" within the meaning of that 
      statute. The trial court ruled that it is not and ordered compliance with 
      the subpoena, and the Court of Appeal held to the same effect. We agree 
      with those rulings, and therefore affirm the judgment of the Court of 
      Appeal. 
 
 | 
  
    | [15] | THE MEDICAL BOARD OF CALIFORNIA 
 
 | 
  
    | [16] | The state has long regulated the practice of medicine as an exercise 
      of the police power. (See, e.g., Stats. 1876, ch. 518, p. 792 ["An Act to 
      Regulate the Practice of Medicine in California"]; Stats. 1913, ch. 354, 
      p. 722 [same]; Stats. 1937, ch. 399, p. 1254 [codifying Medical Practice 
      Act as Bus. & Prof. Code, § 2000 et seq.].) A key instrument of that 
      regulation has been the statewide agency authorized to license and 
      discipline medical practitioners, successively known as the Board of 
      Medical Examiners, the Board of Medical Quality Assurance, and now the 
      Medical Board of California (hereafter the Board), a unit of the 
      Department of Consumer Affairs (Bus. & Prof. Code, § 101, subd. 
      (b)). 
 
 | 
  
    | [17] | Since the earliest days of regulation the Board has been charged with 
      the duty to protect the public against incompetent, impaired, or negligent 
      physicians, and, to that end, has been vested with the power to revoke 
      medical licenses on grounds of unprofessional conduct (e.g., Stats. 1876, 
      ch. 518, § 10, p. 794). In recent years the Legislature has provided the 
      Board with tools of increasing power and sophistication to assist it in 
      that task. (See, e.g., Stats. 1990, ch. 1597, § 1, p. 7683; Stats. 1993, 
      ch. 1267; Stats. 1995, ch. 708.) We deal here, however, with a tool that 
      the Board has possessed at least since 1921: the investigative subpoena. 
      (Stats. 1921, ch. 602, § 1, p. 1023 [adding former Pol. Code, § 353]; 
      Stats. 1945, ch. 111, § 3, p. 439 [recodifying former Pol. Code, § 353, as 
      Gov. Code, § 11181].) To appreciate the role of the Board's subpoena power 
      it will be helpful to review briefly the authority and operation of the 
      Board as a whole. 
 
 | 
  
    | [18] | The Board currently consists of two divisions. (Bus. & Prof. Code, 
      § 2003.) Its Division of Licensing is responsible for approving medical 
      education programs, administering the licensing examination, and issuing 
      licenses to practice. (Id., § 2005.) Its Division of Medical Quality, 
      which we are concerned with here, is responsible for reviewing the quality 
      of medical practice, conducting disciplinary proceedings in cases of 
      unprofessional conduct, and generally enforcing the disciplinary and 
      criminal provisions of the Medical Practice Act. (Id., § 
  2004.) 
 
 | 
  
    | [19] | A primary power exercised by the Board in carrying out its enforcement 
      responsibilities is the power to investigate : the statute broadly vests 
      the Board with the power of "Investigating complaints from the public, 
      from other licensees, from health care facilities, or from a division of 
      the board that a physician and surgeon may be guilty of unprofessional 
      conduct." (Bus. & Prof. Code, § 2220, subd. (a).) The Board delegates 
      its authority to conduct such an investigation to its executive director 
      and its staff of professional investigators. (Id., § 2224.) The Board's 
      investigators have the status of peace officers (id., § 160), and possess 
      a wide range of investigative powers. In addition to interviewing and 
      taking statements from witnesses, the Board's investigators are authorized 
      to exercise delegated powers (Gov. Code, § 11182) to "Inspect books and 
      records" and to "Issue subpoenas for the attendance of witnesses and the 
      production of papers, books, accounts, documents and testimony in any 
      inquiry [or] investigation . . . in any part of the state." (Id., § 11181, 
      subds. (a), (e).) 
 
 | 
  
    | [20] | Because the statute authorizes the Board to issue a subpoena "in any 
      inquiry [or] investigation" (Gov. Code, § 11181, subd. (e)), the Board may 
      do so for purely investigative purposes; it is not necessary that a formal 
      accusation be on file or a formal adjudicative hearing be pending. ( 
      Brovelli v. Superior Court (1961) 56 Cal. 2d 524, 528 [15 Cal. Rptr. 630, 
      364 P.2d 462].) Indeed, such investigations often do not result in formal 
      charges or hearings. (Ibid.) We further observed in the cited case that 
      "As has been said by the United States Supreme Court, the power to make 
      administrative inquiry is not derived from a judicial function but is more 
      analogous to the power of a grand jury, which does not depend on a case or 
      controversy to get evidence but can investigate 'merely on suspicion that 
      the law is being violated, or even just because it wants assurance that it 
      is not.' " ( Id. at p. 529, quoting from United States v. Morton Salt Co. 
      (1950) 338 U.S. 632, 642-643 [94 L. Ed. 401, 410-411, 70 S. Ct. 
      357].) 
 
 | 
  
    | [21] | The Board's subpoena power, nevertheless, is judicially enforced: in 
      the event that its subpoena is disobeyed, the Board may petition the 
      superior court for an order compelling compliance. (Gov. Code, § 11186, 
      11187.) After a hearing, "If it appears to the court that the subpoena was 
      regularly issued . . ., the court shall enter an order that the person 
      appear before the officer named in the subpoena at the time and place 
      fixed in the order and testify or produce the required papers. Upon 
      failure to obey the order, the person shall be dealt with as for contempt 
      of court." (Id., § 11188.) 
 
 | 
  
    | [22] | The Board is also authorized to order a licensee to personally submit 
      to two types of examinations. First, after investigation by a medical 
      expert the Board may order a licensee to take a professional competency 
      examination if there is reasonable cause to believe that the licensee is 
      "unable to practice medicine with reasonable skill and safety to 
      patients." (Bus. & Prof. Code, § 2292, subd. (a).) *fn1 
      Second, the Board may order a licensee to undergo a physical or 
      psychiatric examination if it appears the licensee is "unable to practice 
      his or her profession safely because the licentiate's ability to practice 
      is impaired due to mental illness, or physical illness affecting 
      competency . . . ." (Id., § 820.) Each of these examinations is an 
      investigatory, not an accusatory, procedure. ( Smith v. Board of Medical 
      Quality Assurance (1988) 202 Cal. App. 3d 316, 322-324 [248 Cal. Rptr. 
      704] [Bus. & Prof. Code, § 2292]; Alexander D. v. State Bd. of Dental 
      Examiners (1991) 231 Cal. App. 3d 92, 96-97 [282 Cal. Rptr. 201] [Bus. 
      & Prof. Code, § 820].) 
 
 | 
  
    | [23] | If, after such investigation as it deems necessary, the Board 
      determines there is sufficient evidence of unprofessional conduct to 
      warrant instituting a formal disciplinary action against a licensee, it 
      refers the matter to the Attorney General; the action will then be 
      prosecuted by the Senior Assistant Attorney General of the Health Quality 
      Enforcement Section (see Gov. Code, § 12529) and the proceedings will be 
      conducted in accordance with the Administrative Procedure Act (id., § 
      11500 et seq.). (Bus. & Prof. Code, § 2230, subd. (a).) The Board may 
      also petition for injunctive relief against any licensee whenever it has 
      "reasonable cause to believe that allowing such person to continue to 
      engage in the practice of medicine would endanger the public health, 
      safety, or welfare" (id., § 2313; see also Gov. Code, § 11529 ["interim 
      order" suspending license, etc., on same ground].) If, after formal 
      adjudicative proceedings, the licensee is found guilty of unprofessional 
      conduct, the Board has a range of options: it may either suspend or revoke 
      the license, or place the licensee on probation, or issue a public 
      reprimand. (Bus. & Prof. Code, § 2227.) Finally, the Board's authority 
      to order probation includes the authority to require the licensee to 
      obtain additional professional training and pass an examination thereon, 
      and to submit to a complete diagnostic examination, as well as the 
      authority to restrict the extent or nature of the licensee's practice. 
      (Id., § 2228.) 
 
 | 
  
    | [24] | It is apparent from the foregoing statutes that the purpose of the 
      Board is to protect the health and safety of the public. This Conclusion 
      is confirmed by two additional provisions of the code. First, the Board 
      shares the general purpose of public protection served by all agencies of 
      the Department of Consumer Affairs. (Bus. & Prof. Code, § 101.6.) 
      Second, the Legislature has recently specified that in exercising its 
      disciplinary authority, "Protection of the public shall be the highest 
      priority" of the Board (id., § 2229, subd. (a)); and that although the 
      Board must promote the goal of rehabilitating the erring licensee whenever 
      possible, "Where rehabilitation and protection are inconsistent, 
      protection shall be paramount" (id., subd. (c)). *fn2 
 
 | 
  
    | [25] | It is equally apparent that the "public" thus protected by the Board 
      is the public at large, i.e., all consumers of medical services in 
      California. This is because the Board is an agency of statewide 
      jurisdiction: it licenses and disciplines all physicians and surgeons in 
      California, not simply those practicing in a particular medical facility; 
      and when it restricts, suspends, or revokes a license, it affects the 
      licensee's right to practice throughout the state, not simply in a 
      particular institution. We state these largely self-evident facts in order 
      to contrast the Board with the entities we discuss next. 
 
 | 
  
    | [26] | HOSPITAL PEER REVIEW COMMITTEES 
 
 | 
  
    | [27] | Every licensed hospital has a formally organized and self-governing 
      medical staff responsible for "the adequacy and quality of the medical 
      care rendered to patients in the hospital." (Cal. Code Regs., tit. 22, § 
      70703, subd. (a).) The medical staff is required to adopt rules for 
      "appropriate practices and procedures to be observed in the various 
      departments of the hospital" (id., subd. (e)), and to keep minutes of its 
      meetings and retain them in the hospital files (id., subd. (c)). The 
      medical staff acts primarily through a number of peer review committees. 
      These committees evaluate physicians applying for staff privileges, 
      establish standards and procedures for patient care, assess the 
      performance of physicians currently on staff, and review such matters as 
      the need for and results of each surgery performed in the hospital, the 
      functioning of the patient records system, the control of in-hospital 
      infections, and the use and handling of drugs within the hospital. (Id., 
      subds. (b) & (d); Comment, Anatomy of the Conflict Between Hospital 
      Medical Staff Peer Review Confidentiality and Medical Malpractice 
      Plaintiff Recovery: A Case for Legislative Amendment (1984) 24 Santa Clara 
      L.Rev. 661, 668, fn. 36 (hereafter Peer Review 
    Confidentiality).) 
 
 | 
  
    | [28] | A peer review committee may informally investigate a complaint or an 
      incident involving a staff physician. If the committee proposes to 
      recommend that the privileges of the physician be restricted or revoked 
      because of the manner in which he or she exercised those privileges, the 
      physician is entitled to written notice of the charges and may request a 
      formal hearing. (Bus. & Prof. Code, § 809.1.) If a hearing is 
      requested, it must be conducted pursuant to strictly circumscribed 
      procedures. (Id., § 809.2-809.6.) 
 
 | 
  
    | [29] | If a hospital restricts or revokes a physician's staff privileges as a 
      result of a determination by a peer review body, the discipline must be 
      reported to the Medical Board. (Bus. & Prof. Code, § 805.) The statute 
      imposes this reporting requirement on all peer review bodies, which are 
      defined to include the medical staff of any licensed health care facility 
      and any representative medical society or committee that reviews the 
      quality of professional care. (Id., subd. (a)(1).) The chief of staff or 
      administrator of any such peer review body must file a report with the 
      Board whenever, as a result of that body's action and for a "medical 
      disciplinary cause or reason," *fn3 
      a licensee's application for staff privileges is denied, or staff 
      privileges are revoked, or restrictions on staff privileges are imposed or 
      voluntarily accepted, or a licensee resigns or takes a leave of absence. 
      (Id., subd. (b).) The report must name the licensee and provide "a 
      description of the facts and circumstances of the medical disciplinary 
      cause or reason" and any other relevant information. (Ibid.) The report 
      must be filed within 15 days after the effective date of the discipline, 
      and a supplemental report must be filed within 30 days after the licensee 
      has satisfied any conditions of the discipline. Failure to file such a 
      report, whether or not intentional, is punishable by a civil penalty of up 
      to $5,000; an intentional failure to do so is a crime punishable by a fine 
      of up to $10,000. (Id., subds. (g) & (h).) *fn4 
 
 | 
  
    | [30] | In addition, if a proceeding initiated by a peer review committee 
      against a staff physician results in disciplinary action required to be 
      reported under the foregoing statute, the Board is entitled to inspect and 
      copy the statement of charges, the exhibits introduced at the hearing, and 
      the opinion, findings, or Conclusions of the hearing officer. (Bus. & 
      Prof. Code, § 805.1.) 
 
 | 
  
    | [31] | Finally, it is unprofessional conduct for a physician to practice in 
      any hospital with a staff of more than four physicians unless the hospital 
      requires its medical staff members to conduct regular peer review of their 
      clinical experience (Bus. & Prof. Code, § 2282, subd. (c)), and to 
      ensure compliance the Board is authorized to inspect the "medical staff . 
      . . records" of the institution (id., § 2226). 
 
 | 
  
    | [32] | It is apparent that these statutes implement the Legislature's finding 
      and declaration that "Peer review, fairly conducted, will aid the 
      appropriate state licensing boards in their responsibility to regulate and 
      discipline errant healing arts practitioners." (Bus. & Prof. Code, § 
      809, subd. (a)(5).) 
 
 | 
  
    | [33] | It is also apparent, however, that a hospital peer review committee 
      differs from the Board in several ways. First, it is not a public agency 
      created and funded by the state, but a group of private physicians 
      selected by and from the staff of a hospital. *fn5 
      Second, the conduct of the errant physician is not reviewed by 
      independent, professional investigators, but by the physician's own 
      colleagues practicing in the same hospital: it is, by definition, a peer 
      review committee. By weeding out incompetent or impaired staff physicians, 
      therefore, the peer review process--in addition to its public protection 
      function--inevitably also serves the private purpose of reducing the 
      exposure of the hospital to potential tort liability. Third, the "public" 
      protected by the peer review process is not the public at large, but is 
      limited to the patients of the particular hospital in question. The 
      process is institution specific: a physician stripped of staff privileges 
      by one hospital is not ipso facto prevented from obtaining or maintaining 
      such privileges at other hospitals--the only entity with the power to 
      prevent that from happening is the Board. *fn6 
 
 | 
  
    | [34] | FACTS *fn7 
 
 | 
  
    | [35] | In the spring of 1992 several nurses at Alameda Hospital (hereafter 
      the Hospital) observed Dr. A., an anesthesiologist on the medical staff of 
      the Hospital, behaving while on duty as if he were under the influence of 
      narcotic drugs. 
 
 | 
  
    | [36] | The first incident took place one evening in March 1992. Dr. A. was 
      the anesthesiologist on call when a patient required emergency surgery. As 
      Dr. A. was interviewing the patient, Nurse Larson observed that his speech 
      was slurred. In discussing the case with him before surgery, she saw that 
      his attention and comprehension were impaired. Dr. A. subsequently 
      administered a general anesthetic to this patient. Following the surgery, 
      Nurse Larson reported Dr. A.'s abnormal behavior to her 
    supervisor. 
 
 | 
  
    | [37] | The second incident occurred in late May 1992. A patient was awaiting 
      scheduled surgery, but Dr. A. could not be found. After being paged 
      several times he arrived and began interviewing the patient. Nurse Larson 
      observed that his speech was even more slurred than during the first 
      incident. She promptly called her supervisor and expressed her "grave 
      concern" about Dr. A.'s condition. Thereafter the patient was taken into 
      the operating room and Dr. A. administered sedation 
    intravenously. 
 
 | 
  
    | [38] | On another day that month Nurse McKenna was trying to take a patient 
      into a bathroom but found the door locked. A visitor told her that someone 
      had been in the bathroom for a long time. Nurse McKenna unlocked the door 
      and found Dr. A. asleep in the room with his surgical pants down around 
      his knees. He did not respond to his name, and Nurse McKenna had to shake 
      him several times in order to rouse him. When he awoke, Dr. A. was 
      disoriented and unsteady; in Nurse McKenna's opinion, he "did not behave 
      like someone who had simply fallen asleep." She told Dr. A. that he was 
      needed in surgery; he responded "OK," and went off to the operating room. 
      Suspecting that Dr. A. was taking drugs, Nurse McKenna looked 
      unsuccessfully for drug paraphernalia after he left. She then reported the 
      incident to her supervisor. Later that day another nurse (Nurse McClure) 
      told Nurse McKenna that Dr. A.'s behavior in the recovery room had been 
      "strange" and he had had to lay his head on a desk. 
 
 | 
  
    | [39] | Approximately six weeks thereafter, Nurse McKenna noticed that Dr. 
      A.'s handwriting was shaky on several occasions, and again reported it. 
      She also saw that Dr. A. had made an entry in a record--possibly a 
      patient's chart--stating that he had broken an ampule of Fentanyl during a 
      procedure. *fn8 
 
 | 
  
    | [40] | At some point during this period the Medical Executive Committee of 
      the Hospital medical staff--a peer review committee--began to investigate 
      the matter. Following the bathroom incident, the committee interviewed 
      Nurse McKenna. Dr. A. thereafter appeared before the committee and 
      admitted he had been injecting himself with Fentanyl, which he had taken 
      from the Hospital's narcotics supplies. Dr. A. then requested a leave of 
      absence for the months of October and November 1992 in order to enter an 
      inpatient drug rehabilitation program at the New Bridge Foundation in 
      Berkeley. The request was granted. 
 
 | 
  
    | [41] | As noted above, the code requires that the peer review body report to 
      the Medical Board any leave of absence taken by a staff physician after 
      notice of an investigation into conduct reasonably likely to be 
      detrimental to patient care or safety. (Bus. & Prof. Code, § 805, 
      subd. (b).) The Hospital did not make such a report. 
 
 | 
  
    | [42] | In January 1993 Dr. A. resumed his staff privileges, but under 
      multiple restrictions imposed by the Hospital. These included random 
      supervised urine testing as often as necessary to ensure that he remain 
      drug free, peer review within 24 hours of every case performed, random 
      concurrent review during procedures, daily review of all narcotics records 
      including requirements that all breakages be co-signed and all drugs 
      signed out be accounted for, weekly reports on his outpatient drug 
      rehabilitation program including documentation of ongoing therapy, regular 
      evaluation sessions with the principal medical staff members, and possible 
      use of a narcotic antagonist. 
 
 | 
  
    | [43] | At the same time, Dr. A. entered an outpatient drug rehabilitation 
      program at the Merritt-Peralta Institute in Oakland, agreeing to further 
      restrictions embodied in a "contract" he signed with the "monitoring and 
      re-entry program" of that organization. At the outset of the document he 
      acknowledged that "I am suffering from the disease of chemical 
      dependency." The agreement obligated Dr. A., inter alia, to attend weekly 
      progress and compliance meetings with the monitoring program, to attend 90 
      meetings of a 12-step program, a physician's support group, and a relapse 
      group, to undergo weekly random body fluid analyses with notification of 
      any positive results to the president of the Hospital's medical staff, to 
      participate for 1 year in a narcotic antagonist program, and to obtain a 
      work site monitor authorized to promptly report any suspected drug use or 
      unusual behavior. The agreement was to run for 12 months, from January 7, 
      1993, to January 7, 1994, and could be extended for a second 
    year. 
 
 | 
  
    | [44] | As noted above, the code requires that the peer review body report to 
      the Medical Board any restrictions, whether imposed or voluntarily 
      accepted, on a staff physician's privileges, membership, or employment, 
      for a total of 30 days or more in any 12-month period, because of any 
      conduct reasonably likely to be detrimental to patient care or safety. 
      (Bus. & Prof. Code, § 805, subd. (b)(3).) Again the Hospital did not 
      make such a report. Indeed, both the Hospital's restrictions on Dr. A.'s 
      practice and the "contract" he signed could be read to imply that no 
      report would be made to the Board as long as he did not violate their 
      terms. *fn9 
 
 | 
  
    | [45] | The Board nevertheless learned of this case when a confidential 
      informant reported to it that Dr. A. was a narcotic drug addict who had 
      been under the influence of controlled substances while on duty at the 
      Hospital. The Medical Practice Act contains numerous provisions under 
      which such behavior could be found to be "unprofessional conduct" within 
      the meaning of the act. For example, the following acts constitute 
      unprofessional conduct: any violation of state or federal laws regulating 
      controlled substances (Bus. & Prof. Code, § 2238), self-administration 
      of a controlled substance (id., § 2239), and practice while under the 
      influence of any narcotic drug that impairs the ability to practice safely 
      (id., § 2280). Also relevant here are the general provisions declaring 
      that it is unprofessional conduct to commit a violation of any provision 
      of the Medical Practice Act, or gross negligence, or repeated acts of 
      ordinary negligence, or any act that would have warranted denial of a 
      license. (Id., § 2234.) 
 
 | 
  
    | [46] | The Board initiated the present investigation and assigned the case to 
      Senior Investigator Shane P. Wright. On March 5, 1993, Investigator Wright 
      interviewed the president of the Hospital medical staff and the medical 
      staff coordinator. They informed her that when Dr. A. first applied for 
      privileges some years earlier he admitted that during his residency he had 
      had a "drug problem" but said he had recovered. In this interview 
      Investigator Wright also learned the above recited facts that in 1992 two 
      nurses had complained of Dr. A.'s unusual behavior, that Dr. A. 
      subsequently admitted to injecting himself with Fentanyl, and that he had 
      taken a leave of absence in October and November 1992 to participate in an 
      inpatient drug rehabilitation program. 
 
 | 
  
    | [47] | Investigator Wright thereafter learned the names of the two 
      complaining nurses (Nurse Larson and Nurse McKenna) from a confidential 
      informant, and interviewed them on April 1, 1993. They provided her with 
      the descriptions of their observations of Dr. A.'s behavior that we have 
      summarized above. 
 
 | 
  
    | [48] | On April 2, 1993, Investigator Wright received a letter from the 
      president of the medical staff and the chief executive officer of the 
      Hospital outlining the above listed restrictions that the Hospital placed 
      on Dr. A.'s practice when he returned from his leave of absence, and 
      attaching a copy of Dr. A.'s above discussed "contract" with the drug 
      rehabilitation program of the Merritt-Peralta Institute. 
 
 | 
  
    | [49] | The Hospital also allowed Investigator Wright to interview its 
      pharmacy and surgery personnel and to review its narcotic logs and the 
      patient records in the cases under investigation. The Hospital refused, 
      however, to allow Investigator Wright access to any records involving Dr. 
      A. in the possession of either the Medical Executive Committee or the 
      Credentials Committee. *fn10 
 
 | 
  
    | [50] | Investigator Wright's efforts to obtain information from other sources 
      were also resisted. Thus Investigator Wright invited Dr. A. to an 
      interview with the Board to discuss the incidents under investigation, but 
      on March 17, 1993, Dr. A.'s counsel replied that his client declined the 
      interview. 
 
 | 
  
    | [51] | On March 26, 1993, Dr. A.'s counsel informed Investigator Wright that 
      his client also refused to sign releases to allow the Board to obtain his 
      treatment records from the New Bridge Foundation and the Merritt-Peralta 
      Institute. 
 
 | 
  
    | [52] | Investigator Wright subsequently asked Dr. A. to sign a waiver of a 
      formal petition to compel him to submit to a physical and psychiatric 
      examination (Bus. & Prof. Code, § 820), and to voluntarily agree to 
      such an examination instead. On November 1, 1993, Dr. A.'s counsel 
      informed Investigator Wright that his client refused to agree to the 
      examination. 
 
 | 
  
    | [53] | Investigator Wright then referred the case to Dr. William S. Brostoff, 
      a specialist in addiction medicine, for an evaluation whether Dr. A. was 
      able to practice with safety to the public. (See Bus. & Prof. Code, § 
      820.) On December 10, 1993, the Board received Dr. Brostoff's report, in 
      which he stated that he could not determine whether Dr. A. posed a danger 
      to the public because "I have not been able to review any medical or 
      psychiatric records or evaluations of Dr. A., himself. Specifically, no 
      medical or psychiatric records or evaluations of Dr. A. from his treatment 
      programs are provided. Further, there are no medical or psychiatric 
      updates since the signing of his monitoring and re-entry contract by Dr. 
      A. on January 20, 1993. In addition, Dr. A., through his attorney, 
      declined an invitation for an interview with the investigator. 
      Consequently, I am unable to reach any Conclusions about Dr. A.'s current 
      medical or psychiatric state, the current status of his recovery from 
      chemical dependency or the question of his being a potential danger to 
      himself or others, or finally, whether or not he has impaired ability to 
      conduct a solo practice with safety to the public." Dr. Brostoff 
      recommended that Dr. A. take the above mentioned physical and psychiatric 
      examination. 
 
 | 
  
    | [54] | At this point Investigator Wright turned to the Board's subpoena 
      power. On March 3, 1994, she served a subpoena duces tecum on the New 
      Bridge Foundation and the Merritt-Peralta Institute for any records of Dr. 
      A.'s treatment at those facilities after January 1, 1992. The 
      Merritt-Peralta Institute replied that it could not locate such records, 
      and the New Bridge Foundation refused to comply with the subpoena on the 
      ground that disclosure was prohibited by a federal 
  regulation. 
 
 | 
  
    | [55] | Unable to obtain the information she sought either from the Hospital, 
      from Dr. A., or from his treatment providers, Investigator Wright served a 
      subpoena duces tecum on William J. Dal Cielo, chief executor officer of 
      the Hospital, on April 11, 1994. The subpoena sought, inter alia, 
      information provided by Dr. A. in his application for staff privileges 
      that related to his prior history of drug abuse; copies of complaints 
      received by the Hospital from staff or patients regarding Dr. A. after 
      January 1, 1992; records of the meetings of the Medical Executive 
      Committee concerning Dr. A.'s drug use; documentation of Dr. A.'s leave of 
      absence, of the terms of the Hospital's restrictions on his practice, and 
      of his monitoring and re-entry agreement; and copies of the periodic 
      reports required under those terms and that agreement concerning such 
      matters as Dr. A.'s body fluid testing, compliance with the rehabilitation 
      programs, and response to treatment. 
 
 | 
  
    | [56] | The Hospital refused to comply with the subpoena. On April 29, 1994, 
      the Board, acting through Dixon Arnett, its executive director, filed the 
      present petition for an order to enforce the subpoena. (Gov. Code, § 
      11187.) The Hospital opposed the petition on the grounds that the 
      documents sought by the subpoena were immune from discovery under Evidence 
      Code section 1157 and that the Board failed to show "good cause" for its 
      issuance (see, e.g., Wood v. Superior Court (1985) 166 Cal. App. 3d 1138, 
      1145-1150 [212 Cal. Rptr. 811]). After hearing, the court granted the 
      petition and ordered the Hospital to comply with the 
  subpoena. 
 
 | 
  
    | [57] | The Hospital appealed from the order. In its briefs before the Court 
      of Appeal, the Hospital abandoned its claim of lack of good cause and 
      asserted only its contention that the records sought by the Board were 
      immune from discovery under Evidence Code section 1157. While the appeal 
      was pending, the Board petitioned the superior court for an order 
      compelling the New Bridge Foundation and the Merritt-Peralta Institute to 
      comply with the subpoenas it had served on them for Dr. A.'s treatment 
      records. The court again granted its petition to compel. The New Bridge 
      Foundation, the Merritt-Peralta Institute, and Dr. A. separately 
      challenged this order by petitions for extraordinary relief, and the Court 
      of Appeal granted alternative writs. The Court of Appeal thereafter 
      addressed these petitions and the Hospital's appeal in a single 
      opinion. 
 
 | 
  
    | [58] | First, the Court of Appeal held that the "better view" is that an 
      order compelling compliance with an administrative subpoena is appealable 
      as a final order in a special proceeding, following Millan v. Restaurant 
      Enterprises Group, Inc. (1993) 14 Cal. App. 4th 477, 484-485 [18 Cal. 
      Rptr. 2d 198], and cases cited. The parties do not question that holding 
      here, and it is therefore not before us for review. 
 
 | 
  
    | [59] | Next, the Court of Appeal addressed the writ petitions by the New 
      Bridge Foundation and the Merritt-Peralta Institute, and held that records 
      of drug abuse treatment such as Dr. A. received from those organizations 
      are made confidential by a federal statute and its implementing 
      regulations and by section 11977 of the Health and Safety Code. 
      Accordingly, the Court of Appeal issued a peremptory writ of mandate 
      directing the superior court to vacate its order granting the Board's 
      motion to enforce its subpoenas against the New Bridge Foundation and the 
      Merritt-Peralta Institute. The Board did not seek review of this holding, 
      and it is therefore not before us. 
 
 | 
  
    | [60] | Turning to the Hospital's appeal, the Court of Appeal held that in 
      enacting Evidence Code section 1157 the Legislature did not intend to 
      immunize peer review records from investigative subpoenas by 
      administrative agencies. Accordingly, the Court of Appeal affirmed the 
      order granting the Board's petition to enforce its subpoena for such 
      records. We granted the Hospital's petition for review, and now affirm the 
      judgment of the Court of Appeal. 
 
 | 
  
    | [61] | I 
 
 | 
  
    | [62] | Insofar as relevant here, subdivision (a) of Evidence Code section 
      1157 (hereafter section 1157) provides that "Neither the proceedings nor 
      the records of organized committees of medical . . . staffs in hospitals, 
      or of a peer review body . . . having the responsibility of evaluation and 
      improvement of the quality of care rendered in the hospital, . . . shall 
      be subject to discovery." (Italics added.) There is no question that the 
      Board seeks to obtain hospital peer review committee records within the 
      meaning of section 1157. The sole issue is whether the Board's 
      investigative subpoena is "discovery" within the meaning of this 
      statute. 
 
 | 
  
    | [63] | The Hospital contends that as used in section 1157 the word 
      "discovery" includes subpoenas issued by administrative agencies for 
      investigative purposes. The Board contends, rather, that in section 1157 
      "discovery" means only the formal exchange of evidentiary information 
      between parties to a pending adversary proceeding. The Court of Appeal 
      correctly recognized that "as commonly used in its legal sense, the term 
      is limited as the Board suggests." But the Court of Appeal then reasoned 
      that the Hospital's construction of the term is at least "reasonable," and 
      invoked the rule that when the wording of a statute is "susceptible of 
      more than one reasonable interpretation," the courts resolve the conflict 
      by giving weight to a variety of extrinsic aids such as legislative 
      history, the purpose to be served, and public policy. ( People v. Woodhead 
      (1987) 43 Cal. 3d 1002, 1008 [239 Cal. Rptr. 656, 741 P.2d 
    154].) 
 
 | 
  
    | [64] | In our view, the rule of construction relied on by the Court of Appeal 
      is not here applicable. It is true that courts ordinarily give the words 
      of a statute the usual, everyday meaning they have in lay speech. ( 
      Alexander v. Superior Court (1993) 5 Cal. 4th 1218, 1225 [23 Cal. Rptr. 2d 
      397, 859 P.2d 96].) But that rule has an important exception, and it 
      governs this case: when a word used in a statute has a well-established 
      legal meaning, it will be given that meaning in construing the statute. 
      This has long been the law of California: "The rule of construction of 
      statutes is plain. Where they make use of words and phrases of a 
      well-known and definite sense in the law, they are to be received and 
      expounded in the same sense in the statute." ( Harris v. Reynolds (1859) 
      13 Cal. 514, 518.) 
 
 | 
  
    | [65] | This rule has been declared in our basic codes since they were first 
      enacted in 1872. (Civ. Code, § 13 [words and phrases are to be construed 
      according to "approved usage," but "such others as may have acquired a 
      peculiar and appropriate meaning in law . . . are to be construed 
      according to such peculiar and appropriate meaning"]; accord, Code Civ. 
      Proc., § 16; Pen. Code, § 7, subd. 16; see Prob. Code, § 21122.) The 
      United States Supreme Court follows this rule. (E.g., Bradley v. United 
      States (1973) 410 U.S. 605, 609 [35 L. Ed. 2d 528, 532, 93 S. Ct. 1151] 
      ["Rather than using terms in their everyday sense, '[t]he law uses 
      familiar legal expressions in their familiar legal sense.' "]; Standard 
      Oil Co. v. United States (1911) 221 U.S. 1, 59 [55 L. Ed. 619, 644-645, 31 
      S. Ct. 502], and cases cited.) And it is the general rule in our sister 
      states. (See 2A Sutherland, Statutory Construction (5th ed., 1992 rev.) § 
      47.30, p. 262.) 
 
 | 
  
    | [66] | The rule applies most obviously when the meaning of the word in 
      question is wholly or primarily legal. (E.g., Estate of Ross (1903) 140 
      Cal. 282, 290 [73 P. 976] ["devise" and "legacy"]; Bruner v. Superior 
      Court (1891) 92 Cal. 239, 245 [28 P. 341] ["elisor"]; Texas Commerce Bank 
      v. Garamendi (1992) 11 Cal. App. 4th 460, 475 [14 Cal. Rptr. 2d 854] 
      ["annuities"]; Taylor v. Forte Hotels International (1991) 235 Cal. App. 
      3d 1119, 1123-1124 [1 Cal. Rptr. 2d 189] ["conversion" and "recovery"]; 
      Plotitsa v. Superior Court (1983) 140 Cal. App. 3d 755, 762 [189 Cal. 
      Rptr. 769] ["special and general damages"]; Handlery v. Franchise Tax 
      Board (1972) 26 Cal. App. 3d 970, 981 [103 Cal. Rptr. 465] ["unitary 
      business"].) But the rule is also applicable when the word has both a 
      specific legal meaning and a more general sense in informal legal usage or 
      in lay speech. (E.g., People v. Murray (1994) 23 Cal. App. 4th 1783, 1789 
      [29 Cal. Rptr. 2d 42] ["imprisonment"]; In re Jodi B. (1991) 227 Cal. App. 
      3d 1322, 1328 [278 Cal. Rptr. 242] ["parent"]; Poe v. Diamond (1987) 191 
      Cal. App. 3d 1394, 1398-1399 [237 Cal. Rptr. 80] ["party"]; People v. 
      Heitz (1983) 145 Cal. App. 3d Supp. 8, 17 [193 Cal. Rptr. 138] 
      ["construction" and "improvements"].) In that event the lawmakers are 
      presumed to have used the word in its specifically legal 
  sense. 
 
 | 
  
    | [67] | This is such a case. It is true, as the Hospital contends, that from 
      time to time courts and commentators speak of an administrative agency as 
      using its investigative subpoena power to "discover" evidence for the 
      purpose of deciding whether to charge a statutory violation. (E.g., Okla. 
      Press Pub. Co. v. Walling (1946) 327 U.S. 186, 201 [90 L. Ed. 614, 625, 66 
      S. Ct. 494, 166 A.L.R. 531] [the purpose of an investigative subpoena of 
      the Wage and Hour Administrator is "to discover and procure evidence, not 
      to prove a pending charge or complaint, but upon which to make one if, in 
      the Administrator's judgment, the facts thus discovered should justify 
      doing so."].) To speak in those terms, however, is simply to use the word 
      "discover" in its general sense of finding something out by search or 
      observation, as when we say that a detective "discovered" incriminating 
      evidence at the scene of a murder. 
 
 | 
  
    | [68] | As the Board contends and the Court of Appeal agreed, "discovery" also 
      has a specific legal meaning, to wit, the formal exchange of evidentiary 
      information and materials between parties to a pending action. The two 
      meanings of the word are well recognized in the dictionaries. Thus a 
      leading legal dictionary first defines "discovery" to mean, " In a general 
      sense, the ascertainment of that which was previously unknown; the 
      disclosure or coming to light of what was previously hidden," and gives as 
      example, "the granting of a new trial for newly 'discovered' evidence." 
      (Black's Law Dict. (6th ed. 1990) p. 466, italics added.) But the same 
      work also defines the word in its specifically legal sense, as "The 
      pre-trial devices that can be used by one party to obtain facts and 
      information about the case from the other party in order to assist the 
      party's preparation for trial," and gives as examples such formal 
      procedures as depositions, interrogatories, requests for admission, and 
      motions for production of documents. (Ibid.) Even nonlegal dictionaries 
      draw this distinction, defining "discovery" as "1. The act or an instance 
      of discovering. 2. Something that has been discovered. 3. Law. Data or 
      documents that a party to a legal action is compelled to disclose to 
      another party either prior to or during a proceeding." (Am. Heritage Dict. 
      (2d college ed. 1985) p. 403.) 
 
 | 
  
    | [69] | The Legislature has long been aware of the specific legal meaning of 
      the term "discovery." (E.g., Stats. 1851, ch. 5, § 417, p. 117 [referring 
      to "discovery" by means of depositions of parties].) Almost four decades 
      ago the Legislature enacted the landmark Civil Discovery Act of 1957 
      (Stats. 1957, ch. 1904, § 3, p. 3322), largely based on the discovery 
      provisions of the Federal Rules of Civil Procedure. (See Greyhound Corp. 
      v. Superior Court (1961) 56 Cal. 2d 355, 375-376 [15 Cal. Rptr. 90, 364 
      P.2d 266].) In turn, the provisions of the 1957 act were substantially 
      rewritten and expanded in the Civil Discovery Act of 1986 (Stats. 1986, 
      ch. 1334, § 2, p. 4700), which is currently in effect. Throughout this 
      act, codified in sections 2016 to 2036 of the Code of Civil Procedure, the 
      Legislature repeatedly and consistently uses the term "discovery" only in 
      the foregoing legal sense of the procedures by which parties to a pending 
      action exchange evidence admissible in that action. For example, in 
      defining the scope of discovery under the act the Legislature specifies 
      that "any party may obtain discovery regarding any matter, not privileged, 
      that is relevant to the subject matter involved in the pending action or 
      to the determination of any motion made in that action, if the matter 
      either is itself admissible in evidence or appears reasonably calculated 
      to lead the discovery of admissible evidence." (Id., § 2017, subd. (a), 
      italics added.) 
 
 | 
  
    | [70] | The Legislature exhibited a similarly consistent understanding of the 
      term "discovery" when in 1968 it enacted a special statutory scheme 
      (Stats. 1968, ch. 808, § 3, p. 1561) "provid[ing] the exclusive right to 
      and method of discovery" in proceedings under the Administrative Procedure 
      Act (Gov. Code, § 11507.5), including therefore proceedings brought by the 
      Board to discipline a physician charged with unprofessional conduct. 
      There, too, discovery is defined as the right of "a party" to obtain 
      evidentiary information "upon written request made to another party," but 
      only "After initiation of a proceeding in which [the person charged] is 
      entitled to a hearing on the merits" (id., § 11507.6), i.e., after the 
      process has passed from the investigatory stage to the filing of a formal 
      accusation (id., § 11503-11506). 
 
 | 
  
    | [71] | The Legislature is also well aware of the distinction between 
      discovery and the exercise of the subpoena power; when it wishes to 
      protect a class of evidence from both procedures, it knows how to do so. 
      As noted above, the Board is authorized to order a licensed physician to 
      undergo a physical or psychiatric examination if it appears the licensee's 
      ability to practice is impaired by mental or physical illness. (Bus. & 
      Prof. Code, § 820.) Section 828 of the same code provides in relevant part 
      that "If the licensing agency determines, pursuant to proceedings 
      conducted under Section 820, that there is insufficient evidence to bring 
      an action against the licentiate . . . , then all licensing agency records 
      of the proceedings, including the order for the examination, investigative 
      reports, if any, and the report of the physicians and surgeons or 
      psychologists, shall be kept confidential and are not subject to discovery 
      or subpoena." (Italics added.) If "discovery" included "subpoena," the 
      latter word would be surplusage. Courts should give meaning to every word 
      of a statute if possible, and should avoid a construction making any word 
      surplusage. ( Delaney v. Superior Court (1990) 50 Cal. 3d 785, 798-799 
      [268 Cal. Rptr. 753, 789 P.2d 934], and cases cited.) 
 
 | 
  
    | [72] | The emphasized choice of words, moreover, is deliberate: the 
      Legislature uses the same wording in at least 13 other provisions of the 
      code. For example, if the Board finds insufficient cause to file an 
      accusation against a physician based on the results of a professional 
      competency examination (Bus. & Prof. Code, § 2292), all records of the 
      examination "shall be kept confidential and shall not be subject to 
      discovery or subpoena." (Id., § 2294, subd. (b), italics added; see also 
      id., § 3756, subd. (e) [respiratory care practitioner].) 
 
 | 
  
    | [73] | Again, the Board is authorized to operate a "diversion program" for 
      the treatment and rehabilitation of physicians whose competency is 
      impaired by drug or alcohol abuse. (Bus. & Prof. Code, § 2340.) The 
      code declares that all records pertaining to the treatment of a physician 
      in that program "shall be kept confidential and are not subject to 
      discovery or subpoena." (Id., § 2355, subd. (b), italics added.) The 
      Legislature has made essentially identical provisions for eight other 
      classes of licensees, *fn11 
      and has likewise provided that all records of drug and alcohol treatment 
      and rehabilitation of licensees furnished by providers under contract with 
      any regulatory board in the Department of Consumer Affairs "shall be kept 
      confidential and are not subject to discovery or subpoena." (Id., § 156.1, 
      subd. (b), italics added; see also id., § 4982.2, subd. (g) [records of 
      physical and mental condition of family counselor petitioning for 
      reinstatement after suspension or revocation of license].) 
 
 | 
  
    | [74] | Finally, the Board calls our attention to two recent federal decisions 
      that draw the distinction between discovery and subpoena in different but 
      nevertheless illustrative contexts. Linde Thomson Langworthy Kohn & 
      Van Dyke v. RTC (D.C. Cir. 1993) 5 F.3d 1508, dealt with the Resolution 
      Trust Corporation (RTC), an agency that Congress created to act as the 
      receiver for failed savings and loan institutions and vested with the 
      power to issue investigative subpoenas. In the cited case the RTC began an 
      investigation of a failed Missouri thrift by issuing a subpoena duces 
      tecum to a law firm connected with the thrift. The firm refused to comply 
      with certain portions of the subpoena. On the RTC's petition, the district 
      court ordered compliance. While the firm's appeal was pending, the RTC 
      filed suit against it in federal district court alleging violations of 
      Missouri law. 
 
 | 
  
    | [75] | The Court of Appeals for the District of Columbia Circuit affirmed. 
      Relevant here is the firm's contention that the Missouri law of 
      attorney-client privilege applied and barred the subpoena because the 
      subsequently filed suit would turn on rules of state law. The contention 
      was based on the premise that an administrative investigation is merely an 
      opening stage of subsequent litigation and is the equivalent of a civil 
      discovery procedure. The federal circuit court rejected this premise, 
      observing that "An investigation conducted by the RTC may conceivably 
      neither culminate in litigation, nor be initially designed to inspire it." 
      (5 F.3d at p. 1512.) And such an investigation is not the equivalent of 
      discovery; rather, "Unlike a discovery procedure, an administrative 
      investigation is a proceeding distinct from any litigation that may 
      eventually flow from it." ( Id. at p. 1513.) 
 
 | 
  
    | [76] | E.E.O.C. v. Deer Valley Unified School Dist. (9th Cir. 1992) 968 F.2d 
      904, dealt with the federal Equal Employment Opportunity Commission 
      (EEOC), an agency that is likewise empowered by Congress to issue 
      investigative subpoenas. In the cited case the EEOC began an investigation 
      into the hiring policies and practices of an Arizona school district, 
      issuing an administrative subpoena duces tecum for certain documents. When 
      the school district failed to produce all the documents, the EEOC 
      petitioned the district court for an order of compliance. The district 
      court denied relief because the EEOC had not followed a local rule that 
      required parties to meet and confer before filing a "discovery" motion. 
      The district court found "no reason to treat a subpoena enforcement action 
      such as this, which is in essence pre-litigation discovery, any 
      differently from a more typical discovery request." ( Id. at p. 906.) 
      Although the school district ultimately complied with the subpoena, the 
      district court awarded attorney fees against the EEOC because of its 
      violation of the local rule. 
 
 | 
  
    | [77] | The Court of Appeals for the Ninth Circuit reversed the award, holding 
      that the EEOC's petition to enforce its subpoena was not a "discovery" 
      motion. The court reasoned that "The investigatory subpoena power of the 
      EEOC is based on specific statutory authority, not on the general 
      discovery provisions of the Federal Rules of Civil Procedure." (968 F.2d 
      at p. 906.) In language that echoes our reasoning in the case at bar, the 
      court explained that "The function of administrative investigatory 
      subpoenas differs from that of the discovery provisions of the Federal 
      Rules of Civil Procedure. The discovery provisions apply to actions that 
      have already been filed with the court, and the parties are seeking to 
      develop evidence for the action that is before the court. The statutory 
      subpoena authority, on other hand, is designed for administrative 
      investigations, which may or may not result in any further action before 
      the district court." (Ibid., fn. omitted.) 
 
 | 
  
    | [78] | For all these reasons, the term "discovery" in section 1157 is to be 
      given its well-established legal meaning of a formal exchange of 
      evidentiary information between parties to a pending action, and that 
      meaning does not include a subpoena issued, as here, by an administrative 
      agency for purely investigative purposes. 
 
 | 
  
    | [79] | II 
 
 | 
  
    | [80] | The Hospital raises a number of contentions to the contrary, but none 
      is persuasive. 
 
 | 
  
    | [81] | The Hospital begins by arguing that to construe "discovery" to include 
      an administrative investigative subpoena, as it urges, would serve the 
      purpose or policy that the Legislature sought to promote in enacting 
      section 1157. The Hospital then devotes considerable effort to 
      establishing that the purpose or policy underlying section 1157 is to 
      encourage members of hospital review committees to engage in candid and 
      uninhibited evaluations of the competence of their peers. (See Alexander 
      v. Superior Court, (supra) , 5 Cal. 4th 1218, 1226-1227, and West Covina 
      Hospital v. Superior Court (1986) 41 Cal. 3d 846, 852-854 [226 Cal. Rptr. 
      132, 718 P.2d 119, 60 A.L.R.4th 1257], both quoting from Matchett v. 
      Superior Court (1974) 40 Cal. App. 3d 623, 628-629 [115 Cal. Rptr. 317].) 
      The contention puts the cart before the horse. In determining legislative 
      intent, courts look first to the words of the statute itself: if those 
      words have a well-established meaning, as we hold they do here, there is 
      no need for construction and courts should not indulge in it. ( People v. 
      Jones (1993) 5 Cal. 4th 1142, 1146 [22 Cal. Rptr. 2d 753, 857 P.2d 1163]; 
      DaFonte v. Up-Right, Inc. (1992) 2 Cal. 4th 593, 601 [7 Cal. Rptr. 2d 238, 
      828 P.2d 140]; Solberg v. Superior Court (1977) 19 Cal. 3d 182, 198 [137 
      Cal. Rptr. 460, 561 P.2d 1148].) The Hospital's argument that a different 
      or broader meaning would also serve the purpose or policy underlying 
      section 1157 is an argument that should be made to the Legislature, not to 
      the courts. 
 
 | 
  
    | [82] | The Hospital next asserts that a "broad construction" of the term 
      "discovery" would be "consistent with prior interpretations of the 
      statute," again citing Alexander v. Superior Court, (supra) , 5 Cal. 4th 
      1218. But in Alexander and similar decisions the courts were called upon 
      to construe provisions of section 1157--or to answer questions relating to 
      the coverage of the statute itself--that in the circumstances were 
      susceptible of more than one reasonable interpretation. For the reasons 
      stated above, that is not the case here. 
 
 | 
  
    | [83] | The Hospital also notes that in certain other states, statutes similar 
      to section 1157 provide that peer review committee records shall not be 
      subject to discovery "in any civil action." (See Com'r of Health Services 
      v. Kadish (1989) 17 Conn.App. 577 [554 A.2d 1097, 1099]; Mercy Hosp. v. 
      Dept. of Professional Reg. (Fla.Dist.Ct.App. 1985) 467 So.2d 1058, 
      1059-1060; Unnamed Physician v. Com'n on Medical Dis. (1979) 285 Md. 1 
      [400 A.2d 396, 399-402].) From the fact that in this state section 1157 
      does not include the quoted words, the Hospital infers that the 
      Legislature does intend the term "discovery" in our statute to be broadly 
      construed to extend beyond "civil actions" to include administrative 
      investigative subpoenas. The inference is strained. Although the presence 
      of the quoted words in section 1157 would have facilitated our task--in 
      the three cited cases the courts had no difficulty in holding, as we do 
      here, that peer review committee records are not immune from an 
      administrative investigative subpoena--their absence does not compel a 
      contrary Conclusion: as explained above, our statute uses the term 
      "discovery" in its well-established legal sense and that sense does not 
      include such subpoenas. 
 
 | 
  
    | [84] | The Hospital also relies on the fact that another provision of the 
      Evidence Code (§ 1156, subd. (a)) provides that hospital staff committee 
      records of studies designed to reduce morbidity or mortality are "subject 
      to Sections 2016 to 2036, inclusive, of the Code of Civil Procedure," 
      i.e., the Civil Discovery Act. Again, such a citation in section 1157 
      would have been helpful but its absence does not change the plain meaning 
      of the statute. Indeed, the lack of significance of this very wording is 
      demonstrated by a pair of closely related provisions of the Evidence Code. 
      Section 1156.1, subdivision (a), provides that the records of a certain 
      type of quality assurance committee relating to studies designed to reduce 
      morbidity or mortality are "subject to Sections 2016 to 2036, inclusive, 
      of the Code of Civil Procedure . . . ." The Hospital stresses the fact 
      that the statute expressly cites the Civil Discovery Act rather than 
      saying simply that the records are "subject to discovery." But section 
      1157.6 of the same code, which addresses essentially the same topic, does 
      say simply that such records are "subject to discovery," and the 
      Legislature enacted the two statutes in successive sections of the same 
      bill (Stats. 1982, ch. 234, § 4, 5, p. 767). Thus at least in this portion 
      of the Evidence Code--which includes section 1157, the statute at issue 
      here--the Legislature refers interchangeably to "discovery" and to the 
      Civil Discovery Act. 
 
 | 
  
    | [85] | The Hospital contends that our reading of section 1157 leads to " 
      'absurd consequences' " ( Harris v. Capital Growth Investors XIV (1991) 52 
      Cal. 3d 1142, 1166 [278 Cal. Rptr. 614, 805 P.2d 873]) because after the 
      Board files an accusation, it is assertedly prohibited from discovering 
      the same records that our reading allows it to discover before filing an 
      accusation. The Hospital finds this prohibition in a clause of the 
      Government Code statute that provides generally for discovery under the 
      Administrative Procedure Act after a formal accusation is filed. (Gov. 
      Code, § 11507.6.) That statute lists several categories of discoverable 
      documents, and then declares by way of limitation that "Nothing in this 
      section shall authorize the inspection or copying of any writing or thing 
      which is privileged from disclosure by law or otherwise made confidential 
      or protected as the attorney's work product." (Ibid.) In reply, the Board 
      argues that the Legislature did not intend the quoted clause of Government 
      Code section 11507.6 to incorporate the bar of Evidence Code section 1157 
      against discovery of peer review committee records. Whether the cited 
      Government Code provision bars the Board from discovering peer review 
      committee records after the filing of a formal accusatory proceeding 
      against a physician under the Administrative Procedure Act is not an issue 
      in this case, however, and we decline to decide it. We therefore also 
      decline to speculate that the "absurd consequence" envisioned by the 
      Hospital would in fact flow from our reading of section 
1157. 
 
 | 
  
    | [86] | The Hospital next asserts that our reading of section 1157 makes 
      superfluous a statute that we discussed above, Business and Professions 
      Code section 805.1. As we explained, a hospital peer review committee may 
      conduct formal disciplinary proceedings against a staff physician pursuant 
      to a special statutory procedure. (Id., § 809.2 et seq.) If after such 
      proceedings the hospital imposes formal discipline on the physician that 
      it is required to report to the Board pursuant to section 805, section 
      805.1 entitles the Board to "inspect and copy" the principal documents 
      generated by the hearing, to wit, the statement of charges, exhibits 
      introduced at the hearing, and the opinion, findings, or Conclusions of 
      the hearing officer. (Id., subd. (a).) The Hospital claims there is "no 
      purpose" to the latter statute if the Board already has the general power 
      to obtain peer review committee records by means of an administrative 
      investigative subpoena. 
 
 | 
  
    | [87] | The point is unpersuasive. Prior to the enactment of Business and 
      Professions Code section 805.1 in 1986, if a hospital refused to release 
      peer review records that the Board needed to inspect, the Board was 
      required to issue a subpoena under Government Code section 11181 and, if 
      necessary, to file a proceeding in superior court under Government Code 
      section 11187 to enforce that subpoena. In section 805.1 the Legislature 
      sought to provide the Board with a simpler option in a limited class of 
      cases and for a limited category of records, by giving the Board automatic 
      access to the principal documents generated in any formal disciplinary 
      proceedings conducted by the Hospital. Yet by providing the Board with 
      this limited additional investigative tool, the Legislature cannot have 
      intended to strip it ipso facto of its broad preexisting power under the 
      Government Code to issue subpoenas to investigate all cases of 
      unprofessional conduct, whether or not they resulted in formal 
      disciplinary proceedings by the hospital. The Hospital's argument reads 
      too much into the modest aim of section 805.1. 
 
 | 
  
    | [88] | Section 1157 contains several express exceptions to its prohibition 
      against the discovery of peer review committee records. *fn12 
      The Hospital next contends that our reading of section 1157 adds a new 
      exception to the statute--for administrative investigative subpoenas--and 
      therefore violates the rule of construction that " 'where exceptions to a 
      general rule are specified by statute, other exceptions are not to be 
      implied or presumed.' " ( Mutual Life Ins. Co. v. City of Los Angeles 
      (1990) 50 Cal. 3d 402, 410 [267 Cal. Rptr. 589, 787 P.2d 996], quoting 
      from Wildlife Alive v. Chickering (1976) 18 Cal. 3d 190, 195 [132 Cal. 
      Rptr. 377, 553 P.2d 537].) 
 
 | 
  
    | [89] | That rule of construction, however, applies only when a court proposes 
      to create an "exception" to a "rule," and a true "exception" is a case 
      that would otherwise be included within the rule. That is not the case 
      here. For the reasons stated above, the "rule" of section 1157 is that 
      peer review committee records are immune from "discovery" in the sense of 
      a formal exchange of evidentiary information between parties to a pending 
      action; because an administrative investigative subpoena is not 
      "discovery" in that sense, it would not be within the scope of section 
      1157 in any event, and our holding excluding it does not create an 
      "exception" to the statute. 
 
 | 
  
    | [90] | The Hospital invokes one last rule of statutory construction. On March 
      4, 1993, a lengthy and complex bill was introduced in the Legislature 
      (Sen. Bill No. 916) that proposed a large number of changes in the several 
      statutes governing the discipline of health care professionals. *fn13 
      The bill was amended no less than nine times during its passage through 
      the Legislature in the ensuing six months, and many sections were added, 
      omitted, or rewritten. *fn14 
      It was finally passed and signed into law in September 1993. (Stats. 1993, 
      ch. 1267.) One of the provisions of the original bill that was omitted in 
      the midst of this process--in the fourth of its nine amendments, on June 
      3, 1993--would have added a clause to section 1157 reciting that "Nothing 
      in this section shall be construed to prevent the discovery of evidence 
      relevant to a disciplinary proceeding or investigation against a licensee 
      by the applicable licensing board." From the fact that the quoted clause 
      was not adopted, the Hospital infers that the Legislature intends the 
      opposite, i.e., that section 1157 shall be construed to prevent "the 
      discovery of evidence relevant to . . . [an] investigation" of a licensee 
      by the Board. In support, the Hospital invokes a rule of construction, 
      found in several Court of Appeal decisions, to the effect that " ' "The 
      rejection by the Legislature of a specific provision contained in an act 
      as originally introduced is most persuasive to the Conclusion that the act 
      should not be construed to include the omitted provision." ' " ( Crespin 
      v. Kizer (1990) 226 Cal. App. 3d 498, 514 [276 Cal. Rptr. 
  571].) 
 
 | 
  
    | [91] | In reply, the Board relies on a distinction drawn by another Court of 
      Appeal between a failure to enact a proposed provision of a new statute 
      and a failure to enact a proposed amendment to an existing statute, 
      concluding that "there is relatively little value in examining an existing 
      statute in light of proposed amendments which have not been approved." ( 
      Save-on Drugs, Inc. v. County of Orange (1987) 190 Cal. App. 3d 1611, 1623 
      [236 Cal. Rptr. 100].) 
 
 | 
  
    | [92] | Although the distinction would be sufficient to defeat the Hospital's 
      contention in this case because section 1157 had been in existence for 25 
      years when Senate Bill No. 916 proposed to amend it, we question the 
      soundness of the Hospital's rule of construction itself. In most cases 
      there are a number of possible reasons why the Legislature might have 
      failed to enact a proposed provision. One reason might have been, of 
      course, that the Legislature rejected the proposal on its merits. But the 
      Legislature might equally well have been motivated instead by 
      considerations unrelated to the merits, not the least of which is that it 
      might have believed the provision unnecessary because the law already so 
      provided: in the case at bar, for example, the Legislature could well have 
      believed that section 1157 did not need amending because its prohibition 
      against "discovery" did not include administrative investigative subpoenas 
      in any event. Indeed, when as here a provision is dropped from a bill 
      during the enactment process, the cause may not even be a legislative 
      decision at all; it may simply be that its proponents decided to withdraw 
      the provision on tactical grounds. 
 
 | 
  
    | [93] | Because these reasons apply equally to a failure to enact a new 
      statute and to a failure to amend an existing statute, we decline to draw 
      any such distinction: both cases are governed by our often stated rule 
      that "Unpassed bills, as evidences of legislative intent, have little 
      value." ( Dyna-Med, Inc. v. Fair Employment & Housing Com. (1987) 43 
      Cal. 3d 1379, 1396 [241 Cal. Rptr. 67, 743 P.2d 1323]; accord, Santa Clara 
      County Local Transportation Authority v. Guardino (1995) 11 Cal. 4th 220, 
      238 [45 Cal. Rptr. 2d 207, 902 P.2d 225]; Granberry v. Islay Investments 
      (1995) 9 Cal. 4th 738, 746 [38 Cal. Rptr. 2d 650, 889 P.2d 970].) Under 
      that rule, the inference that the Hospital seeks to draw from the 
      legislative history of Senate Bill No. 916 is unpersuasive. 
 
 | 
  
    | [94] | Finally, the Hospital contends that to immunize peer review committee 
      records from administrative investigative subpoenas "would do little, if 
      any, harm to the Board's disciplinary function" because the Board can 
      assertedly obtain much of the same information from other sources. Like 
      the Hospital's first contention, this is an argument that should be made 
      to the Legislature, not to the courts. *fn15

      "Reasonable cause" IS DEFINED AS ONE OR MORE OF: "(1) a single incident of 
      gross negligence; (2) a pattern of inappropriate prescribing; (3) an act 
      of incompetence or negligence causing death or serious bodily injury; or 
      (4) a pattern of substandard care." (Bus. & Prof. Code, § 2292, subd. 
      (a).)

    | [98] | *fn2 
      We take no position on whether the quoted amendments to Business and 
      Professions Code section 2229 in 1990 were a substantive change in the law 
      or merely a clarification of existing law. (See Borden v. Division of 
      Medical Quality (1994) 30 Cal. App. 4th 874 [35 Cal. Rptr. 2d 
      905].) 
 
 | 
  
    | [99] | *fn3 
      A "medical disciplinary cause or reason" is defined as any aspect of a 
      licensee's competence or professional conduct that is "reasonably likely 
      to be detrimental to patient safety or to the delivery of patient care." 
      (Bus. & Prof. Code, § 805, subd. (a)(6).) 
 
 | 
  
    | [100] | *fn4 
      The Legislature imposes similar reporting requirements on other persons 
      and agencies. (Bus. & Prof. Code, § 800-803.6.) For example, a 
      judgment, settlement, or arbitration award against a licensee in a 
      malpractice action must be reported to the Board by the appropriate court 
      clerk, by the insurer or employer who pays it, or by the defendant 
      licensee if uninsured. In such a case the Board has specific authority to 
      "Investigat[e] the circumstances of practice" of the licensee in question. 
      (Id., § 2220, subd. (b).) Any felony indictment, information, or 
      conviction of a licensee must be reported to the Board by the prosecuting 
      agency, the court clerk, and the defendant licensee, and copies of any 
      preliminary hearing transcript and probation report must be sent to the 
      Board. Coroners must also report to the Board any pathologist's findings 
      that a death may be the result of a licensee's gross negligence or 
      incompetence.

      It bears remembering that "So-called staff physicians should be 
      distinguished from the resident physicians who are employed by the 
      hospital. Staff physicians are private doctors granted medical staff 
      privileges to treat their patients in the hospital setting." (Peer Review 
      Confidentiality, (supra) , 24 Santa Clara L.Rev. 661, 664, fn. 
    14.)

      In an effort to reduce the likelihood of such "hospital shopping," the 
      Legislature also provides that before granting or renewing staff 
      privileges for any physician, a hospital must ask the Board if it has 
      received a report of disciplinary action by any other hospital against 
      that physician. (Bus. & Prof. Code, § 805.5, subd. (a).) The Board 
      will furnish a copy of any such report unless the discipline was based 
      solely on a failure to complete medical records, or the information 
      reported is without merit, or the report is more than three years old. 
      (Id., subd. (b).)

      The following facts are taken from the principal pleading herein--the 
      Board's petition for an order to compel compliance with its administrative 
      subpoena, together with its declaration in support of that subpoena. No 
      objection has been raised to the accuracy of the facts there 
      alleged.

      Fentanyl, an opiate, is a Schedule II controlled substance. (Health & 
      Saf. Code, § 11055, subd. (c)(8).)

      Item 8 of the Hospital's restrictions provided that the "first infraction" 
      would be "reported to the Medical Board of California." Item 14 of the 
      "contract" provided that the consequences of a relapse or noncompliance 
      could include "notification to the Board of Medical Quality Assurance 
      [i.e., the Medical Board]."

      The Credentials Committee, another peer review committee, had reviewed Dr. 
      A.'s application for staff privileges.

      2770.12 [registered nurse], 3534.7 [physician assistant], 4436

      The principal exceptions are: "The prohibition relating to discovery . . . 
      does not apply to the statements made by any person in attendance at a 
      meeting of any of those committees who is a party to an action or 
      proceeding the subject matter of which was reviewed at that meeting, or to 
      any person requesting hospital staff privileges, or in any action against 
      an insurance carrier alleging bad faith by the carrier in refusing to 
      accept a settlement offer within the policy limits." (§ 1157, subd. (c); 
      see also id., subds. (d), (e).)

      The bill was 47 pages in length and contained 35 sections, many of which 
      made multiple changes in the relevant statutes. 
 
 | 
  
    | [110] | *fn14 
      By the time of its final version the bill had grown to 60 pages in length 
      and contained 62 sections.

      Shortly before oral argument the Hospital filed two requests asking us to 
      take judicial notice of (1) an order of the Board dated September 15, 
      1995, directing Dr. A. to submit to a psychiatric examination pursuant to 
      Business and Professions Code section 820, and (2) a report dated June 10, 
      1996, on the outcome of that examination by the psychiatrist who conducted 
      it. Both events occurred long after the trial court entered its judgment 
      on May 15, 1994, and the Hospital took this appeal. We are therefore 
      governed by the general rule that an appellate court will consider only 
      matters that were part of the record at the time the judgment was entered. 
      ( Reserve Insurance Co. v. Pisciotta (1982) 30 Cal. 3d 800, 813 [180 Cal. 
      Rptr. 628, 640 P.2d 764].) No exception to that rule is here applicable. 
      For this reason the requests for judicial notice are 
  denied.
