People v. Drew, 22 Cal. 3d 333 (1978), was a case decided by the California Supreme Court that abandoned the M'Naghten Rules of the criminal insanity defense in favor of the formulation in the Model Penal Code.[1] The decision was later abrogated by Proposition 8 in 1982, which restored the M'Naghten rules.[2]
