OPINION OF THE COURT
Involved in this appeal are questions of vicarious liability of a physician operating a clinic and of the effect with respect to a successive tort-feasor of a release given to the original tort-feasor. As to the first, we conclude that a physician who owns a medical clinic which is held out to the public as offering medical services may be held vicariously liable for the malpractice of a treating doctor even though the owner-physician neither participates in nor controls the diagnosis made or treatment prescribed. As to the second, we hold that General Obligations Law § 15-108 (a) imposes upon the plaintiff who releases the original tort-feasor the burden of proving the extent to which his release reduces his claim against a hospital or physician who through malpractice aggravates the original injuries. The order of the Appellate Division should, therefore, be modified and the case remitted to Supreme Court, New York County, for a further hearing on the effect of plaintiff’s release of the original tort-feasors and, as so modified, should be affirmed, with costs to plaintiff against defendant Bono and costs to defendant St. Clare’s Hospital against plaintiff.
I
Plaintiff Birdell Hill was injured on June 30, 1972, when a sidewalk elevator plummeted some 18 feet into a subcellar, causing pain in his feet, shoulder and wrist. He was taken to St. Clare’s Hospital, where his feet were X-rayed, but was told by the hospital doctors that no bones were broken and that he had suffered "soft tissue injury.” His right ankle was wrapped
Some years before, Hill had been a patient at The Benjamin A. Gilbert Medical Clinic, an industrial medical practice then run by Dr. Gilbert, and he had also taken an injured coworker to that clinic for treatment. On the day following his own injury, Hill went to the Gilbert Clinic. The clinic had been run by Dr. Benjamin Gilbert for some 40 years on West 45th Street in Manhattan. Faced with the need for emergency surgery and concerned lest his patients turn to other physicians during his absence, Dr. Gilbert asked defendant Bono, a friend and practicing physician, to use the name Benjamin A. Gilbert Medical Clinic while he was incapacitated. Dr. Bono agreed and began to use the name of the clinic at a suite of offices leased by him on West 44th Street. He also arranged for two secretaries and two physicians (Carranza and De Nalfi) formerly with Dr. Gilbert to move into the West 44th Street offices, where all three physicians treated their own patients as well as those of Dr. Gilbert. Dr. Gilbert never practiced at the West 44th Street office, however, because the ailment which caused his hospitalization proved fatal.
Plaintiff knew none of the clinic doctors by name when he visited the clinic the day following his injury and it is undisputed that he was never seen professionally by Dr. Bono at the clinic or elsewhere. On his first visit he was seen by either Dr. Carranza or Dr. De Nalfi, who looked at his wrist and ankle and requested the hospital X rays. Several days later, after obtaining the hospital X rays and taking a second set of his own, Dr. Carranza applied a cast to plaintiff’s right foot. Plaintiff testified that in addition to the fact that his right foot "looked funny” and was "curved toward the right,” the large toe of his left foot was "sticking up a bit.” He visited the clinic on five or six other occasions through early August, when Dr. Carranza referred him to Dr. Selig Strax.
Dr. Strax testified that plaintiff suffered not only fractures of the second, third and fourth metatarsal bones of his right foot but also a complete dislocation of his left great toe which had not been diagnosed by St. Clare’s Hospital or by either Dr. Carranza or Dr. De Nalfi, that plaintiff’s having attempted to walk on the foot for six or seven weeks following the injury had necessitated surgery and had resulted in a permanent deformity, known as a "hammer toe,” as well as other complications.
At the close of plaintiffs’ case and at the close of the entire case, defendant Bono moved to dismiss on the ground that he had never seen Birdell Hill professionally and that Dr. Carranza was an independent contractor. The motion was denied and the case went to the jury under a charge,
On appeal by defendants to the Appellate Division, that court affirmed, holding unanimously (although by a 3 to 2 split as to the reasons) that denial of any offset for the settlement with the original tort-feasors was proper and, over the dissent of the two of its members, that sufficient evidence had been presented to require submission to the jury of the question of Dr. Bono’s liability for the negligent acts of Dr. Carranza. Defendant Bono both appealed as of right and moved before the Appellate Division for leave to appeal, apparently to obviate any finality question resulting from the stipulation deferring the new trial as to Mamie Hill.
A
Although a hospital or other medical facility is liable for the negligence or malpractice of its employees (Bing v Thunig,
While vicarious liability for medical malpractice generally turns, therefore, on agency or control in fact (see generally, Ann., 69 ALR2d 305), we have also, in Hannon v Siegel-Cooper Co. (
The principle of the Hannon case is accepted in both the Restatement (Second) of Agency § 267,
B
Applying those principles, we conclude that there was sufficient evidence to require submission to the jury of the questions, set forth in note 2 above, whether Dr. Bono was the owner of The Benjamin A. Gilbert Medical Clinic and held the clinic out as offering medical services to the public through any of the physicians practicing in it. As noted above, plaintiffs prior relationship was with the clinic rather than any of the three physicians, and he did not ask to see any particular physician. The report to the Workers’ Compensation Board was signed in Dr. Bono’s name individually, the bill submitted for the services rendered to plaintiff bore the name of the clinic, over which was typed Dr. Bono’s name, and payment was made to Dr. Bono. Dr. Bono testified that he owned the practice known as The Benjamin A. Gilbert Medical Clinic, that the clinic rendered medical services to patients in much the same way as a hospital clinic and that a patient would go "because you know you’re going to be rendered medical service” and because "there was a medical service available on 45th Street to go to.” There was a checking account in the name of the clinic on which only Dr. Bono had the right to draw checks and into which all payments for services rendered by Dr. Bono, or by either of the other doctors when the person served was not a "personal patient [of his] and had just
There was, to be sure, contradictory evidence from Dr. Bono concerning his relationship with the other two doctors, the reason for his name on the report and the bill and the reason for the draw of the other two doctors, among other things, but in determining whether the evidence was sufficient to go to the jury we consider only whether on the evidence taken in the light most favorable to plaintiff a prima facie case has been made out, not the weight of the evidence (Alexander v Eldred,
Ill
As to the effect of plaintiffs’ release of the original tortfeasors, however, the courts below erred.
The original tort-feasors were liable not only for the injuries incurred by Birdell Hill as a result of the elevator’s fall but also for the aggravation of those injuries through the malpractice of St. Clare’s Hospital as well as the malpractice of Dr. Carranza for which Dr. Bono has been determined to be responsible (Milks v McIver,
The common-law rule was that release of the original wrongdoer barred an action against a hospital or physician for the additional injury or damages resulting from the latter’s unskillful treatment of the original injury (Malvica v Blumenfeld,
The reference to "two or more persons liable or claimed to be liable in tort for the same injury” covers successive as well as joint tort-feasors, as the Law Revision Commission report emphasizes by reference to Milks v McIver (supra; 1972 McKinney’s Session Laws of NY, at 3237) and as was held in Roma v Buffalo Gen. Hosp. (
It is the latter concept which we applied in Derby v Prewitt in holding on "considerations of reason and basic fairness” (
There is, however, a material difference between what Derby required plaintiff to prove — what was intended — and what must be proved under General Obligations Law § 15-108. Under subdivision (a) of that section, the claim of the releasor is reduced by the greatest of (1) the amount stipulated by the release, (2) the amount of the consideration paid for it, or (3) the released tort-feasor’s equitable share of the damages. To the extent that the injured party and the original tort-feasor are permitted to stipulate the amount by which the liability of the successive tort-feasor is to be reduced by the original tort
The third criterion — the released tort-feasor’s equitable share of the damages — involves a seeming contradiction, however. Under CPLR 1402 "equitable shares shall be determined in accordance with the relative culpability of each person liable” for contribution. But, as we have seen, the original tort-feasor’s right to recover from the successive malpracticing doctor or hospital arises by way to subrogation to the rights of the injured party, and is a right to complete indemnity, rather than contribution, for the aggravation damages. When the two statutes are read together in the light of their respective legislative histories,
A further hearing pursuant to CPLR 4533-b must, therefore, be held by the Trial Judge. The object of the hearing will be to determine what portion of the settlement payment by the original tort-feasors was for the original injuries and what portion was for the aggravation injuries. (In the present action, in which only the subsequent tort-feasors are defendants, damages have been awarded for the injuries they caused — the aggravation injuries.) Any portion of the settlement payment found to be attributable to the aggravation injuries must be offset against plaintiffs’ recovery against
At the contemplated hearing, the trier of fact will first determine the amount paid to plaintiffs in settlement by the original tort-feasors, which may or may not be the amount recited in the release. Next, he will allocate that amount between the two plaintiffs, based upon the reasonable intent of the parties. Third, the fact finder should determine what portion, if any, of the settlement payment should be attributed to each plaintiff’s aggravation damages. In so doing he will consider the statement as to allocation, if any, between original and aggravated injuries contained in the settlement documents and the gravity of the respective injuries and determine whether the amount allocated by the parties was arrived at in good faith. Finally, if as to either plaintiff the fact finder allocates any portion of the settlement payment to the aggravation injuries, he should deduct that portion from the damages awarded that plaintiff and direct that judgment be entered for the difference. The resultant amount will then be apportioned, as found by the jury, 30% to St. Clare’s Hospital and 70% to Dr. Bono.
Accordingly, the order of the Appellate Division should be modified and the case remitted to Supreme Court, New York County, for a further hearing in accordance with this opinion and, as so modified, should be affirmed, with costs to plaintiff against defendant Bono and costs to defendant St. Clare’s against plaintiff. The certified question is not answered as unnecessary.
Chief Judge Wachtler and Judges Simons, Kaye and Ti-tone concur; Judges Alexander and Hancock, Jr., taking no part.
Order modified, etc.
Notes
. Defendant Carranza defaulted but the action as to him was dismissed because plaintiffs waited until trial (more than a year after default) to move for entry of judgment (CPLR 3215 [a], [c]).
. The jury was told that as to Dr. Bono the issues for its decision were: "Was Dr. Rudolph Bono the owner of the Benjamin Gilbert Medical Center? Did the Gilbert Medical Center furnish medical treatment to the plaintiff, as distinguished from Dr. Carranza and Dr. DeNalfi, individually, independent from Dr. Bono, treating the plaintiff? Did the Gilbert Medical Center commit negligence or medical malpractice? If so, was this medical malprac
. The ruling as to Mamie Hill is not before us, the parties having stipulated to defer trial of the damage issue as to her until determination of the present appeal.
. The Appellate Division granted leave to Bono and certified the question whether the judgment of Supreme Court as affirmed by it was properly made. Birdell Hill having stipulated to the reduced damages, there is party finality. Accordingly, we do not answer the certified question because unnecessary.
. That section provides: "One who represents that another is his servant or other agent and thereby causes a third person justifiably to rely upon the care or skill of such apparent agent is subject to liability to the third person for harm caused by the lack of care or skill of the one appearing to be a servant or other agent as if he were such.”
. That section, adopted in reliance in part on the Hannon case (see, Reporter’s Notes, Restatement [Second] of Torts, Appendix §§ 402A to 503, at 91), states that: "One who employs an independent contractor to perform services for another which are accepted in the reasonable belief that the services are being rendered by the employer or by his servants, is subject to
. CPLR article 14 covers successive as well as joint tort-feasors (Twentieth Ann Report of NY Judicial Conference, 1975, at 214, 223).
