Commonwealth v. Pugh, 462 Mass. 482 (2012)
A woman was convicted of involuntary manslaughter after attempting an unassisted home childbirth in which her viable fetus died. The trial court found that she used excessive force to accelerate delivery, and failed to call for medical help despite recognizing a breech positioning. On appeal, the Supreme Judicial Court reversed, holding that the Commonwealth had not proven her actions caused the death, and that failing to call for help was not a legally sufficient cause of death.
