Today we are asked to address the relationship among the three members of a medical malpractice tribunal convened pursuant to G. L. c. 231, § 60B (1988 ed.). Specifically, we are faced with the question whether the decision of a medical malpractice tribunal as to the sufficiency of a plaintiff’s offer of proof must conform to the conclusion of the tribunal’s judicial member, in spite of the contrary views of the medical and legal members. We rule that the decision of a majority of the panel members shall determine the finding of the tribunal. Therefore, the judge sitting as a member of the tribunal was without power to rule that the plaintiff’s offer of proof was sufficient to raise a legitimate question of liability appropriate for judicial inquiry where a majority of the panel found otherwise. However, since the issue is fully briefed and legitimately before us, we take this opportunity to review the offer of proof made by the plaintiff. We determine that the plaintiff’s offer of proof was sufficient and that the plaintiff should have been allowed to proceed without posting a bond, consistent with the decision entered. We, therefore, affirm.
The plaintiff’s claim arises from the treatment of the plaintiff’s husband, the decedent Joseph V. Kopycinski, while he was a patient at Massachusetts General Hospital (MGH). On December 31, 1986, the decedent went to MGH’s emergency ward complaining of vomiting, inability to eat, and excessive weight loss. The decedent was examined by defendant Hopkins, who admitted the decedent to the hospital. Thereafter, Dr. Hopkins consulted with Dr. Aserkoff, also a defendant, as to the decedent’s treatment. Dr. AserkofFs notes concerning the decedent appear throughout the medical records. Dr. Aserkoff ordered a number of tests, including an abdominal CT-Scan, to determine the cause of the decedent’s condition. Although the CT-Scan showed evidence of an inguinal hernia, the defendant physicians allegedly failed to *412determine that the hernia was the cause of the decedent’s medical problems.
On January 6, 1987, less than twenty-four hours before his death, the defendant doctors obtained a surgical consultation from Dr. Carter. Dr. Carter recommended an exploratory laparotomy after the decedent’s condition was stabilized. On January 7, 1987, the decedent died while an inpatient at MGH.
On November 20, 1989, the plaintiff, Catherine Kopycin-ski, filed a complaint for medical malpractice against the defendants. The complaint alleged that the defendants had failed to properly identify and treat the decedent’s medical condition, and that the decedent suffered damages as a result of this failure. On March 26, 1990, a medical malpractice tribunal (tribunal), convened pursuant to G. L. c. 231, § 60B, to review the plaintiff’s offer of proof. The tribunal consisted of a physician, an attorney, and a judge of the Superior Court. The attorney and the physician found in favor of each defendant. The judge, however, overruled the majority, stating that, as a matter of law, the plaintiff’s offer of proof was sufficient. The judge then ordered that the plaintiff could proceed with her case without posting a bond.
The defendants filed a petition pursuant to G. L. c. 231, § 118 (1988 ed.), for interlocutory review of the tribunal’s findings. A single justice of the Appeals Court granted leave to the defendants to file this interlocutory appeal. We transferred the case on our own motion. We determine that the judicial member of the tribunal had no power to overrule the decision of the majority of the panel.
General Laws c. 231, § 60B (1988 ed.), provides for the screening claims of medical malpractice by a tribunal. The statute states, in part, that “[ejvery action for malpractice, error or mistake against a provider of health care shall be heard by a tribunal consisting of a single justice of the superior court, a physician licensed to practice medicine in the commonwealth under the provisions of section two of chapter one hundred and twelve and an attorney authorized to practice law in the commonwealth, at which hearing the plaintiff *413shall present an offer of proof and said tribunal shall determine if the evidence presented if properly substantiated is sufficient to raise a legitimate question of liability appropriate for judicial inquiry or whether the plaintiff’s case is merely an unfortunate medical result.” The statute provides that, if the tribunal finds for the defendant, the plaintiff may pursue the claim through the regular judicial process, but only upon filing a bond in the amount of $6,000.
The plaintiff argues that the question which the tribunal is ultimately asked to resolve is a legal one and, thus, solely within the purview of the judicial member of the tribunal. The defendants rely on our decision in Paro v. Longwood Hosp., 373 Mass. 645 (1977), arguing that the question for the tribunal is not a legal question and should be decided by the majority vote of the tribunal. We agree with the defendants. The question to be decided ultimately by the tribunal is a factual one. The plain meaning of the statute, and the legislative guidelines for interpreting statutes which involve tribunals, make it clear that the Legislature intended that a majority vote of the tribunal would determine whether a plaintiff’s offer of proof is sufficient.
The words of the statute themselves suggest that the tribunal’s decision is a factual and not a legal determination. Words such as “legitimate” and “appropriate,” which are used to describe the standard of proof, suggest determinations of fact. Moreover, the statute repeatedly refers to the “finding” of the tribunal, once again suggesting that the task of the tribunal is a fact-finding mission. Perhaps most telling is the “either,” “or” language used in the framing of the tribunal’s task. The tribunal determines whether the evidence is “sufficient to raise a legitimate question of liability appropriate for judicial inquiry or whether the plaintiff’s case is merely an unfortunate medical result” (emphasis supplied). Surely the determination whether a medical result is merely “unfortunate” is not a legal determination. The plain meaning of the words used within the statute suggests that the task of the tribunal is fact-finding, for which the judicial *414member is no better equipped than the legal or medical member.
Furthermore, the Legislature has issued clear rules as to how a statute such as c. 231, § 60B, is to be interpreted. General Laws c. 4, § 6 (1988 ed.), provides that, unless such a construction would be “inconsistent with the manifest intent of the law-making body or repugnant to the context of the same statute .... [w]ords purporting to give a joint authority to, or to direct any act by, three or more public officers or other persons shall be construed as giving such authority to, or directing such act by, a majority of such officers or persons.” It is clear from this statute that the Legislature intended that, by setting up a tribunal in G. L. c. 231, § 60B, and stating “said tribunal shall determine if the evidence presented ... is sufficient,” that a majority vote of the tribunal members would determine the decision of the tribunal (emphasis added).
The plain meaning of the language “said tribunal shall determine” says that the tribunal as a whole, and not one particular member, shall make the determination. When the Legislature intended for the judicial member to have specific powers with regard to the tribunal, it said so explicitly. For instance, § 60B provides that the judge is to select the health service professional and the attorney who are to serve as co-members on the tribunal; the section also provides that the judicial member may increase or decrease the amount of the bond to be filed.
We note that the judicial member of the tribunal would certainly be solely responsible for deciding purely legal issues. In Paro v. Longwood Hosp., 373 Mass. 645, 656-657 (1977), we rejected the plaintiffs argument that the tribunal statute violated art. 30 of the Massachusetts Declaration of Rights because it allows the two lay panel members to override the judge in the decision of legal issues. The Paro court stated that “[t]he lawyer and the health service representative are placed on the panel because of their expertise in relevant fields. This expertise is useful in deciding the primary question faced by the tribunal — whether the plaintiff has *415presented a legally sufficient claim. As to the determination of this issue, the tribunal decision is a collective one, with all three panel members participating equally. The responsibility for deciding purely legal questions, however, is left solely with the judge-member of the tribunal, and thus no interference with his function occurs.” (Emphasis supplied.) Id. at 657. The proposition set forth in Paw is that the primary question the tribunal must answer is not a legal question and is, therefore, to be decided collectively by the panel members, with all three as equal participants. Decisions such as the admissibility of evidence proffered to the tribunal would fall the purely legal category to be determined by the judicial member only.
One year later, in Little v. Rosenthal, 376 Mass. 573 (1978), we clarified the standard by which the tribunal is to judge the plaintiff’s offer of proof. We determined that the language set forth in the statute that the tribunal was to “determine if the evidence presented ... is sufficient to raise a legitimate question of liability appropriate for judicial inquiry” or whether the plaintiffs case is merely an unfortunate medical result made it “clear that the tribunal’s mandate is to evaluate evidence.” Id. at 578. Therefore, we determined in Little that, in light of this language, the tribunal’s task is comparable to a trial judge’s function in ruling on a motion for a directed verdict.
The plaintiff contends that Little set forth the proposition that the tribunal’s standard is that of a motion for a directed verdict and, since this is a legal standard, the judge should make the final decision. We disagree. We stated in Little that the standard by which a tribunal would evaluate evidence could be “compared to” the standard for a directed verdict. We did not say that the standards were one and the same. Indeed, in Little, we were merely attempting to clarify the standard in light of an erroneous argument that the standard was the equivalent to that for a motion to dismiss under Mass. R. Civ. P. 12 (b) (6), 365 Mass. 754 (1974). Little v. Rosenthal, supra at 578. In substance, we said that the standard which the tribunal shall use is closer to a motion for a *416directed verdict standard than it is to a rule 12 (b) (6) standard.
Moreover, our decision in Broadard v. Hubbard Regional Hosp., 388 Mass. 1012 (1983), supports our determination that the tribunal must come to a decision as a whole. In Broadard, the judicial member felt that it was clear that the offer of proof would be sufficient to raise a legitimate question of liability appropriate for judicial inquiry, and that he intended to find for the plaintiff. Therefore, the judge did not convene the tribunal, seeing it as a “needless exercise.” We reversed the judge’s decision stating that, even though the judge was certain, the statute called for an interplay among the judicial, legal, and medical members. Here, we determine that c. 231, § 60B, not only requires a convening of the tribunal, but also an interplay in which all three members play an equal role in determining the outcome.
General Laws c. 231, § 60B, is to be read so as to require a determination by a majority vote of the panel. To determine that the very question that the -tribunal is convened to answer is a legal question, purely for the judge member to decide, would be repugnant to the plain meaning of the statute, to the statutory rules of construction set forth by the Legislature, to our decision in Paro which states the decision is to be collective, and to a commonsense reading of the statute. In sum, the judicial member of the tribunal had no power to overrule the determination of the other panel members and decide that the plaintiff had offered enough proof to proceed without posting a bond.
However, since the issue is properly before us, we will review the offer of proof that was made by the plaintiff to determine its sufficiency.3 The plaintiff argues that, even if the *417judge were incorrect as to the authority of the panel, he was correct on the sufficiency of the offer of proof. We agree that the offer of proof was sufficient.
“A plaintiff’s offer of proof as to negligence will prevail before a malpractice tribunal ... (1) if a doctor-patient relationship is shown, (2) if there is evidence that the doctor’s performance did not conform to good medical practice, and (3) if damage resulted therefrom.” Kapp v. Ballantine, 380 Mass. 186, 193 (1980). The defendants’ answer admits the allegation of the complaint that they all “rendered medical care and treatment to Joseph V. Kopycinski while he was an in-patient at the Massachusetts General Hospital.” Thus, the first prong of the test is satisfied. As to the second and third prongs, the defendants contend first that the plaintiff’s expert relied on erroneous factual assumptions in forming his opinion that negligence occurred, and second that the plaintiff did not offer sufficiently particularized proof as to each one of them to establish individual liability.
The plaintiff’s offer of proof included an affidavit of a surgeon, Dr. Richard E. Kessler. Dr. Kessler opined that the failure to diagnose and to treat the decedent for an inguinal hernia fell below the standard of care of the average quali-tied practitioner and caused his death. Specifically, he stated that the treating physician should have (1) diagnosed a hernia as the cause of the lump in the groin, (2) diagnosed an inguinal hernia as the cause of the bowel obstruction, (3) called for an early surgical consultation, (4) performed an exploratory laparotomy, and (5) put a tube into the decedent’s stomach. The defendants contend that Dr. Kessler’s conclusions are based on erroneous factual assumptions because (1) there is evidence in the medical records that an inguinal hernia was diagnosed, and (2) the physicians did obtain a surgical consultation. The plaintiff responds that it was the failure to diagnose the hernia as the cause of the symptoms, not the failure to diagnose it at all that constitutes the alleged negligence; and that it was the failure to obtain an early surgical consultation that fell below the requisite standard of care. In any event, on a directed verdict standard, *418the evidence must be viewed in the light most favorable to the plaintiff. Any factual dispute as to the “meaning” of the record is for the jury. But even assuming the defendants’ argument is meritorious, Dr. Kessler identified two other instances of negligence — the failure to do an exploratory lap-arotomy and the failure to put a tube in the decedent’s stomach. Thus, we reject the contention that the offer of proof fails because it is based on erroneous factual assumptions.
The defendants also contend that the plaintiff did not offer sufficiently particularized proof as to the negligence of each defendant individually. Dr. Kessler’s affidavit asserts that “each of the physicians at the Massachusetts General Hospital who participated in Mr. Kopycinski’s care and treatment and the decision-making concerning his diagnosis and treatment was responsible for the delays referred to and for his death.” The defendants contend that the failure to identify each of them by name and to state specifically which acts of theirs were negligent renders the offer of proof insufficient.
The affidavit states that each of the physicians participating in the decedent’s care was responsible for his death. The defendants have admitted that they rendered medical care to the decedent. Contrast Grassis v. Retik, 25 Mass. App. Ct. 595, 604 (1988) (upholding directed verdict in favor of admitting physician who took no part in care of patient). Thus, the second prong of the sufficiency test is satisfied because there is evidence that each of them, as physicians participating in the decedent’s care, “did not conform to good medical practice.” The third prong also is satisfied because the affidavit states that the failure to diagnose and treat the decedent for an inguinal hernia caused his death. Therefore, we hold that the two panel members erred in deciding that the plaintiff’s offer of proof in regard to the three physician defendants is not sufficient to raise a legitimate question of liability appropriate for judicial inquiry.
The defendant Massachusetts General Hospital claims that the plaintiff’s offer of proof is insufficient as to it because she “has produced no evidence of negligence on the *419part of an employee, agent, or servant” of the hospital. “The question whether the individual defendant was a person for whose conduct the defendant hospital would be responsible [is] beyond the competence of the tribunal.” Flagg v. Scott, 9 Mass. App. Ct. 811, 812 (1980). See DiGiovanni v. Lattimer, 390 Mass. 265, 272 (1983). The plaintiff alleged that a “John Doe” or “Richard Roe” was negligent and was an agent or employee of the hospital. She has also made a sufficient offer of proof of the physician defendants’ negligence. The question of their relationship to the hospital is one to be sorted out at trial.
In sum, we hold that the tribunal’s determination is to be decided by a majority vote. However, we determine that the offer of proof was sufficient. The decision entered below by the judicial member of the panel was that the offer of proof was sufficient for the plaintiff to proceed without posting a bond. We affirm that decision, and remand the case to the Superior Court.
So ordered.
The issue of sufficiency of the evidence is properly before the court. The plaintiff argues that, even if the judge were incorrect as to the authority of the panel, he was correct on the sufficiency of the offer of proof. “A party who prevails in the Superior Court may present on appeal any ground which was previously asserted below. . . .” Boston Edison Co. v. Boston Redevelopment Auth., 374 Mass. 37, 43 (1977). Thus, the plaintiff is entitled to have the court consider this issue.
