Three Wicked Sisters Law and Legal Definition

Three Wicked Sisters is a slang term. The three common law defenses: contributory negligence, fellow servant rule, and assumption of risk, used by the 19th century court to deny recovery to the on job injured workers became known as the three wicked sisters. These doctrines were so known because of their preclusive effect on the ability of the injured workers to recover.

The Workman's Compensation Act abolished the common-law requirement of negligence and the three wicked sisters of the common law; contributory negligence, assumption of risk and the fellow servant rule. [Inland Mfg. Div., Etc v. Lawson, 14 Ohio Misc. 129 (Ohio Misc. 1967)].
