Osteopathic Physicians & Surgeons v. California Medical Association, 224 Cal. App. 2d 378 (Cal. App. 2d Dist. 1964) was a legal case between two medical associations in the state of California. The case was under review in California state courts from 1962-1964. After numerous appeals, the California Supreme Court ruling found the California Medical Association's refusal to grant osteopathic physicians licensure to practice medicine in the state of California to be unconstitutional.
