211 N.Y. 125, 105 N.E. 92 (Court of Appeals of New York 1914)
Schloendorff v. Society of New York Hospital is a cornerstone of American tort law best known for Justice (then-Judge) Benjamin Cardozo's iconic declaration: "Every human being of adult years and sound mind has a right to determine what shall be done with his own body." That sentence has echoed through generations of cases and scholarship as the doctrinal seed of modern informed consent, anchoring the principle that medical interventions without a patient's authorization constitute a legal wrong—historically framed as a battery when there is no consent at all.
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.
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.
