OPINION OF THE COURT
SEITZ, Chief Judge.This is an appeal from a lower court monetary judgment in favor of the plaintiff in a diversity action based on negligence. The action was initiated by a pro-se complaint of a former inmate in a prison operated by the Commonwealth of Pennsylvania. The plaintiff sued the superintendent of the prison in which he was confined and two physicians associated with the prison who had treated him for an injury sustained during his imprisonment. The plaintiff alleged that the medical treatment which he received with respect to his injury was negligent and that all three defendants were responsible for this negligent care. The lower court, which heard the case without a jury, found that the defendant physicians had been negligent and were liable to the plaintiff since they were not protected by sovereign immunity. The court, however, held that the defendant superintendent, by virtue of his office and duties, was immune from suit. The defendant physicians have appealed, alleging that they, as public officers, are also immune from suit.
Since we are of the opinion that the evidence supports the lower court’s finding of negligence on the part of the physicians, the essential issue on this appeal is whether they are shielded from plaintiff’s suit because they are officers of the Commonwealth of Pennsylvania.
Factual Background
The cause of action in this case arose out of a series of events commencing around 2:00 p.m. on January 24, 1968, at Graterford prison in Montgomery County, Pennsylvania, the correctional facility in which plaintiff was confined. At that time the plaintiff, who was unloading a truck, slipped on a piece of ice in the truck bed and fell, injuring his right wrist as he attempted to break his fall. Shortly thereafter, the plaintiff reported to the prison infirmary where he was examined by the defendant Dr. Anderson, who was the prison’s full-time physician. At that time, Dr. Anderson diagnosed the wrist injury as a sprain.
The following day, the plaintiff was examined by the defendant, Dr. Place, who worked for the prison on a part time basis. After the examination by Dr. Place, the plaintiff’s wrist was xrayed. Almost a week later, on January 30, 1968, the x-ray report was made revealing that the navicular bone in the plaintiff’s right wrist had been fractured. Despite the medical standard prevalent in Montgomery County in 1968, which the district court found to require that a patient with a broken bone be instructed to keep the injured area immobilized and that consultation with an orthopedic specialist be provided as soon as possible, the defendant physicians failed to inform plaintiff that his wrist was broken. They also chose to *333comply with a prison administrative rule then in effect which required there to be fifteen inmates in need of consultation with an orthopedic specialist — regardless of the time any number less than fifteen had to wait — before such a specialist could be brought into the prison.
Because of the negligence of the defendant physicians, the plaintiff was not even placed on the “list of fifteen” until February 8, 1968, a full two weeks after the navicular bone in his right wrist was fractured. As a result of the defendants’ negligent decision to follow an administrative rule which directly contravened the standards for practice of their profession, the plaintiff did not actually see an orthopedic specialist until April 11, 1968, two and one half months after his injury.
On April 11, the orthopedic specialist placed a cast around the plaintiff’s wrist. From that time until some time in August of the same year, the plaintiff wore a cast on his wrist. Throughout the entire period, the plaintiff continued to work as a mechanic since defendants did not execute a medical work release in his behalf. Moreover, the defendants did not recommend to the warden that the plaintiff should be relieved of his duties, despite a Pennsylvania statute in effect at that time which required:
The [prison] physician shall inquire into the mental as well as the bodily state of every prisoner, and when he shall have reason to believe that the mind or body is materially affected by the discipline, treatment, or diet, he shall inform the warden thereof, and shall enter his observation on the journal hereinafter directed to be kept, which shall be an authority for the warden for altering the discipline, treatment or diet of any prisoner, until the next meeting of the inspectors, who shall inquire into the case and make orders accordingly. Pa. Stat.Ann., tit. 61, § 372 (1964).
In August, when the cast was removed from his wrist, the plaintiff was informed that the two segments of the navicular bone had failed to knit. The lower court concluded that the failure to heal could be attributed to the defendants’ negligence in (1) failing to see to it that the plaintiff’s wrist was immobilized at an early stage, (2) failing to immediately arrange consultation between plaintiff and an orthopedic specialist, (3) failing to execute a medical release in behalf of the plaintiff so that he would not be required to perform his duties as a mechanic, and (4) failing to comply with Section 372 of Title 61, Pa.Stat. Ann. (hereinafter “Section 372”). The lower court found that as a result of the defendants’ negligence, the plaintiff had suffered a substantial impairment of the use of his right hand.
The defendants contend that this is in reality a suit against the Commonwealth and is accordingly controlled by early cases which hold that the Commonwealth and its agents are shielded from suit under the doctrine of sovereign immunity.1 In advancing this contention, the defendants argue that this case falls within the rule enunciated in Biello v. Liquor Control Board, 454 Pa. 179, 301 A.2d 849 (1973).
Biello involved a wrongful death action against the Pennsylvania Liquor Control Board and its individual members. In that case, the Supreme Court of Pennsylvania, having concluded that the individual defendants were “nominal parties to the record” and that the suit was, in effect, a suit against an agency of the Commonwealth, held that the Board was immune from suit since it was performing a governmental function. See also Brown v. Commonwealth, 453 Pa. 566, 305 A.2d 868 (1973).
We do not believe, as the defendants contend, that the individual defendants in this case, like those in Biello, are merely “nominal parties to the record” and that the present action is in reality a suit against the Commonwealth. We think that Biello can be distinguished from the case at bar because in Biello, *334none of the persons sued were individually the perpetrators of the acts that allegedly were the direct cause of the personal injuries which were the gravamen of the suit in that case. The plaintiff in Biello alleged that the Commonwealth, the liquor control board, its individual members, and the manager of a retail store were liable for the sale of liquor to a minor who subsequently became intoxicated and, allegedly because of his intoxicated state, plunged from a fire escape to his death.
In Biello the defendants were not actors; they were sued because of their official responsibilities with respect to the retail sale of liquor on the theory that they should be held vicariously liable. Here, however, plaintiff sues two actors, whose decision to act in one way and whose failure to act in another were found by the lower court to be the proximate cause of plaintiff’s injuries. We therefore believe that the instant case is governed by Pennsylvania decisions dealing with suits against public officials as individuals.
Montgomery v. Philadelphia, 392 Pa. 178, 140 A.2d 100 (1958), relied upon by the district court in reaching its decision in the case at bar, is one of the most significant Pennsylvania cases dealing with suits against public officials as individuals. Montgomery involved a damage action grounded in slander that was brought by a contractor, who had undertaken to build two buildings for the City of Philadelphia, against two city officials. The defendants claimed they were immune from suit.
In responding to this defense, the Supreme Court of Pennsylvania noted that there are two forms of official privilege commonly recognized in this country. Under both, conduct otherwise actionable escapes liability because it is in furtherance of some socially important interest. The first form is qualified immunity. It shields a public official who acts in the performance of his official duties so long as the plaintiff cannot prove that the official has abused the privilege by acting in an improper manner, or did not have reasonable justification for his actions.
The second form is absolute immunity. It shields an official absolutely, that is to say, without regard for whether he had reasonable justification for his actions, so long as he acted in the course of his official duties.
The Montgomery court noted that not every official was protected by absolute immunity. The Court stated:
[Wjhether a particular public officer is protected by absolute privilege should depend upon the nature of his duties, the importance of his office, and particularly whether or not he has policy-making functions. Id. at 105.
However, the Court found that both city officials involved in the case before it were entitled to absolute immunity.
Although Montgomery was a defamation case, a subsequent opinion of the Pennsylvania Supreme Court, Jonnet v. Bodick, 431 Pa. 59, 244 A.2d 751 (1968), specifically stated that the Montgomery rule was not to be limited to defamation cases. Moreover, despite the municipal context of the suit in Montgomery, we think the doctrine enunciated in that case was intended to apply to public officers generally. Thus, the Montgomery dichotomy of high and low officials is potentially applicable to the instant case. Montgomery, however, because it was concerned with the immunity of high officials, never indicated the nature and extent of the “qualified” immunity which is extended to low officials. A recent decision of the Superior Court of Pennsylvania, Ammlung v. City of Chester, 224 Pa.Super. 47, 302 A.2d 491 (1973), suggests that the qualified immunity to which lower officials are entitled affords them protection with respect to any exercise of discretion which is not reckless, wanton or malicious.2 Indeed, *335this is exactly the limitation imposed by an early decision of the Pennsylvania Supreme Court, Yealy v. Fink, 43 Pa. 212 (1862), on the immunity held by certain public officials involved in that case.3
No case has come to our attention that applies the Montgomery rule as expanded by Ammlung to a damage suit against a low official in the performance of a non-discretionary duty.4 However, we believe that the instant ease presents such a fact situation.
Based on our reading of Yealy, Montgomery and Ammlung, we believe that the rule in Pennsylvania is that persons are deemed low officials if they do not have extensive responsibility to fashion public policies, and if their duties and office are, when judged in the broad context of the state government in its entirety, not so consistently of public significance as to warrant the extension to them of an extraordinary and privileged status.
Applying this rule of law to the defendant physicians we find that neither defendant had sufficiently broad responsibility to formulate public policy or had a sufficiently significant office or sufficiently important duties, when compared with the office and duties of other state officials such as the deputy commissioner of public property or the city architect in Montgomery, to warrant his classification as a “high” official.
As low officials, the defendants’ liability to plaintiff for their tortious action or failure to act is dependent, under Montgomery and Ammlung, upon whether their decision to act or to refrain from acting was left to their discretion by state law. Were defendants performing a discretionary function when they caused plaintiff’s injury, they would only be liable to plaintiff, under Pennsylvania law, if their action or failure to act was reckless, malicious or wanton. Were the defendants performing a non-discretionary function, we believe they could be held liable to plaintiff, under Pennsylvania law, if their action or omission was merely negligent.
Although in the normal performance of their duties as prison physicians, the defendants may have had certain discretionary functions, they also had a statutory duty, under Section 372, to make inquiries concerning the health of each prisoner, and upon learning of physical infirmity affected by prison treatment, to inform the warden of the condition.
This duty was part of a statutory scheme which provided the warden with the opportunity and authority to alter the treatment of a prisoner in order to protect his health.5 The lower court found that the defendant physicians had failed to comply with this statute. We find that the defendant physicians had a non-discretionary duty to comply with the statute. We conclude that as low officials who failed to perform a non-discretionary act, the defendants are not to *336be judged by the “reckless, wanton or malicious” standard, but by the standard of negligence used in malpractice actions generally in Pennsylvania.6
Inasmuch as the district court found the standard of practice in the Montgomery County area at the time of plaintiff’s injury dictated that plaintiff be given a work release and because we are of the opinion that Section 372 provided a statutory mandate with respect to such an alteration of a prisoner’s routine, we conclude that the defendants’ failure to perform the non-discretionary act required by Section 372 constituted negligence when judged by the standards of defendants’ profession. Furthermore, since the district court found that defendants’ failure to comply with Section 372 was a substantial factor in causing plaintiff’s injury to heal improperly, we conclude that the district court was correct in holding defendants liable to plaintiff.7 Finding liability on this one ground renders it unnecessary for us to determine whether the defendants here would be liable to the plaintiff, under Pennsylvania law, in the absence of Section 372.
The judgment of the district court will be affirmed.
. See, e. g., O’Connor v. Pittsburgh, 18 Pa. 187 (1851).
. A decision of the Commonwealth Court of Pennsylvania, Dubree v. Commonwealth, 8 Pa.Cmwlth. 567, 303 A.2d 530 (1973), held:
To place liability upon a public official who is not a high public official, therefore, it is merely necessary to show that the officer *335concerned was not acting within the scope of his authority, and that the conduct complained of was intentional, as well as malicious, wanton or reckless. Id.
. 43 Pa. at 216. The Superior Court of Pennsylvania in Ammlung, supra, apparently concluded that the county supervisors in Yealy were low officials. 302 A.2d at 495.
. Some cases have suggested that duties of a public officer that are nondiscretionary should be deemed “ministerial.” See Ammlung v. City of Chester, supra; 67 C.J.S. Officers § 127 at 422. But courts and commentators alike have expressed discontent with the discretionary-ministerial distinction. See, e. g., Larson v. Domestic & Foreign Corp., 337 U.S. 682, 688, 69 S.Ct. 1457, 93 L.Ed. 1628 (1949); Ove Gustavsson Contracting Co. v. Floete, 299 F.2d 655 (2d Cir. 1962); Jaffe, Suits Against Governments and Officers: Damage Actions, 77 Harv.L.Rev. 209, 218-19 (1968). Although a distinction must, of necessity, be drawn between functions which are discretionary and those which are not, we believe that the labels “discretionary” and “ministerial” are too often used in a manner that tends to preclude careful analysis of a public official’s legal mandate to determine whether that official has, by law, been given discretion to perform a specific act.
. Cases in other jurisdictions have found strong public policies to underly statutory provisions similar to those here. See, e. g., Pisacano v. State, 8 A.D.2d 335, 188 N.Y.S.2d 35 (1959).
. In Pennsylvania the rule is that the doctor is required to: “exercise only such reasonable skill and diligence as is ordinarily exercised in his profession,” Duckworth v. Bennett, 320 Pa. 47, 181 A. 558, 559 (1935), see also Saltzer v. Reckord, 319 Pa. 208, 179 A. 449, 450 (1935), and to give “due regard to the advanced state of the profession and to exercise the care and judgment of a reasonable man in the exercise of medical skill and knowledge.” Incollingo v. Ewing, 444 Pa. 263, 299, 282 A.2d 206, 217 (1971).
. We have no trouble, as does the dissent, in finding that defendants’ failure to comply with Section 372 proximately caused plaintiff’s injury. Although the district court did not use the term “proximate cause,” it did find that defendants’ failure was a substantial factor in causing plaintiff’s injury. The Supreme Court of Pennsylvania has held, in a negligence case where the plaintiff claimed to have been injured by the defendant’s failure to comply with a statutory duty: “It is well settled in Pennsylvania that in order to find that defendant proximately caused an injury it must be found that his allegedly wrongful conduct was a substantial factor in bringing about plaintiff’s injury even though it need not be the only factor.” Majors v. Brodhead Hotel, 416 Pa. 265, 205 A.2d 873, 877 (1965). We have no difficulty finding that plaintiff, in the instant case, was in the class of people protected by Section 372, toward whom defendants had a statutory duty. We think that the expert testimony contained in the record adequately supports the district court’s holding that defendants’ neglect of this duty was a substantial factor in causing plaintiff’s injury. Compare Dornon v. Johnston, 421 Pa. 58, 218 A.2d 808 (1966).
