Is a patient's right to refuse medical treatment paramount to what might otherwise be the doctor's obligation to provide care?

In Storar, we recognized that a patient's right to determine the course of his medical treatment was paramount to what might otherwise be the doctor's obligation to provide medical care, and that the right of a competent adult to refuse medical treatment must be honored, even though the recommended treatment may be beneficial or even necessary to preserve the patient's life (52 N.Y.2d, at p. 377, 438 N.Y.S.2d 266, 420 N.E.2d 64, supra). This fundamental common-law right is coextensive with the patient's liberty interest protected by the due process clause of our State Constitution (cf. Cooper v. Morin, 49 N.Y.2d 69, 80, 424 N.Y.S.2d 168, 399 N.E.2d 1188).
