Mary Schloendorff was admitted to the Society of New York Hospital, a private charitable institution, for a stomach ailment. Physicians discovered a fibroid mass and recommended an examination under ether to assess its nature. Schloendorff expressly consented to the examination but explicitly refused any operation. While she was under anesthesia, the attending surgeons proceeded to operate to remove the mass without her consent. Afterward, she suffered serious complications—allegedly including gangrene and injury to her arm—attributed to negligent medical treatment and the unauthorized operation. Schloendorff sued the hospital, asserting claims sounding in assault and battery for the nonconsensual surgery and negligence for her resulting injuries. The surgeons themselves were not parties to the appeal. Lower courts ruled in favor of the hospital, and Schloendorff appealed to the New York Court of Appeals.
1) Does performing an operation without a competent adult patient's consent constitute an actionable tort (assault and battery)? 2) Is a private charitable hospital vicariously liable for the torts or malpractice of its physicians and nurses arising out of medical treatment?
1) A competent adult has the right to determine what is done to their own body; a medical operation performed without the patient's consent constitutes a battery. 2) Under then-prevailing New York law, a private charitable hospital is not vicariously liable for the negligence or intentional torts of its physicians and nurses in the provision of medical treatment, because such medical personnel are not considered the hospital's servants for purposes of respondeat superior, and public policy favored insulating charitable funds. The hospital may be liable for its own negligence in administrative matters (e.g., unsafe premises, defective equipment) or potentially in negligent selection/retention of staff.
The Court held that an operation performed without a patient's consent is a battery by the surgeons. However, the Court affirmed judgment for the defendant hospital, concluding that a private charitable hospital is not vicariously liable for the torts or malpractice of its physicians and nurses in connection with medical treatment.
Cardozo began by articulating a fundamental principle of personal autonomy: adults of sound mind control what is done to their bodies, and medical interventions without consent are unlawful. On that premise, the surgeons' decision to operate—despite the plaintiff's express refusal—was a battery. The plaintiff's bodily integrity was violated by a nonconsensual touching of a highly invasive sort, and no professional prerogative could override that refusal in the absence of emergency or incapacity. Turning to the hospital's liability, the Court emphasized two intertwined rationales. First, respondeat superior requires a master-servant relationship in which the master controls the details of the servant's work. Physicians and surgeons exercise independent professional judgment; they are not subject to a hospital's day-to-day control over diagnosis and treatment. Nurses, when carrying out medical orders, are likewise engaged in medical care rather than purely administrative tasks. As a result, the hospital could not be cast as a master for purposes of vicarious liability for medical torts. Second, the Court invoked public policy considerations associated with charitable institutions, noting a line of authority shielding charitable hospitals from liability for the malpractice of their medical staff to preserve charitable assets for their intended purposes. The Court distinguished between medical negligence and the hospital's own potential negligence in administrative or corporate functions—such as maintaining premises or equipment—where liability could attach. Because the alleged wrong here—the unauthorized operation and negligent treatment—sounded in medical care, and because there was no showing that the hospital directed or authorized the wrongful act or was negligent in administrative matters, the hospital could not be held liable. The Court thus affirmed the judgment for the hospital while underscoring that the surgeons themselves would be liable for performing a nonconsensual operation. The decision, therefore, both crystallized the autonomy-based rule against nonconsensual medical procedures and entrenched a contemporaneous limit on hospital vicarious liability—one later abandoned by New York in Bing v. Thunig (1957), which rejected the medical/administrative distinction and charitable immunity for hospitals.
For law students, Schloendorff is pivotal on two fronts. First, it is the classic citation for the foundational informed-consent principle: unauthorized medical procedures constitute a battery when there is no consent at all. That doctrinal anchor continues to influence modern tort law, bioethics, and medical practice, even as many jurisdictions now treat inadequate disclosure as negligence rather than battery. Second, the case illustrates the historical doctrine of charitable immunity and the medical/administrative distinction limiting hospital liability—concepts that were widely repudiated in the mid-20th century. Studying Schloendorff clarifies the evolution from physician-centered autonomy and hospital insulation toward modern frameworks recognizing hospital corporate and vicarious liability.
Schloendorff endures for its clear articulation of bodily autonomy: competent patients control medical decision-making, and procedures without consent are unlawful. That core insight seeded the doctrine of informed consent and continues to guide courts, clinicians, and ethicists in structuring patient-physician relationships.
