Married women rank among the "persons in subjection to the power of others;" they thus come among those who in many cases are not criminally liable; "infants under the age of discretion," persons who are _non compotes mentis_ (not of sound mind), and persons acting under coercion, are not criminally liable for their misdeeds. A married woman is presumed to act under her husband's coercion, unless the contrary be proved, and she may thus escape punishment for her wrongdoings: "Constraint of a superior is sometimes allowed as an excuse for criminal misconduct, by reason of the matrimonial subjection of the wife to her husband; but neither a son, nor a servant is excused for the commission of any crime by the command or coercion of the parent or master. Thus, if a woman commit theft, or burglary, by the coercion of her husband, or even in his company, which the law _primâ facie_ construes a coercion, she is dispunishable, being considered to have acted by compulsion, and not of her own will" ("Comm, on the Laws of England," Broom and Hadley, vol. iv., p. 27). "A _feme covert_ is so much favoured in respect of that power and authority which her husband has over her, that she shall not suffer any punishment for committing a bare theft, or even a burglary, by the coercion of her husband, or in his company, which the law construes a coercion" (Russell "On Crimes," vol. i., p. 139). "Where the wife is to be considered merely as the servant of the husband, she will not be answerable for the consequences of his breach of duty, however fatal, though she may be privy to his conduct. C. Squire and his wife were indicted for the murder of a boy;" he had been cruelly treated by both, and died "from debility and want of proper food and nourishment;" "Lawrence, J., directed the jury, that as the wife was the servant of the husband, it was not her duty to provide the apprentice with sufficient food and nourishment, and that she was not guilty of any breach of duty in neglecting to do so; though, if the husband had allowed her sufficient food for the apprentice, and she had wilfully withholden it from him, then she would have been guilty. But that here the fact was otherwise; and therefore, though _in foro conscientiæ_ the wife was equally guilty with the husband, yet in point of law she could not be said to be guilty of not providing the apprentice with sufficient food and nourishment" (Ibid., pp. 144, 145). It is hard to see what advantage society gains by this curious fashion of reckoning married women as children or lunatics. Some advantages, however, flow to a criminal husband: a wife is not punishable for concealing her husband from justice, knowing that he has committed felony; a husband may not conceal his wife under analogous circumstances: "So strict is the law where a felony is actually complete, in order to do effectual justice, that the nearest relations are not suffered to aid or receive one another.
