The question before us then is, whether or not the defendant was entitled to this instruction,—in other words, whether, if the plaintiff’s unlawful act contributed to cause his injury, it was a bar to his recovery, or merely evidence of negligence which might or might not bar him, according to the view which the jury should take of his conduct as a whole, in its relation to the accident.
It has often been held that a violation of law at the time of an accident, by one connected with it, is evidence of his negligence, but not conclusive. Hanlon v. South Boston Horse Railroad, 129 Mass. 310; Hall v. Ripley, 119 Mass. 135; Damon v. Scituate, 119 Mass. 66. In recent times a large number of penal statutes have been enacted, in which the legislature has seen fit to punish acts which are not mala in se, and sometimes when in a given case there is no actual criminal intent. On grounds of public policy, laws have been passed under which a person is bound to know the facts in regard to the subject with which he is dealing, when under possible circumstances ignorance would not be inconsistent with proper care. One who sells milk must know that it is not adulterated. An unlicensed person must know that what he sells is not intoxicating liquor. Commonwealth v. Boynton, 2 Allen, 160. And if in a possible case he trespasses in innocent ignorance, the law gives him no relief. He can only appeal to the sense of justice and the discretion of the public authorities to save him from the punishment which the law would inflict. It is obvious that in suits for negligence, if the contributing conduct of the plaintiff is to be considered as a whole, it may sometimes be found that he has not been guilty of actual negligence or fault, although he has violated the law. One element of his action may be neglect of a duty prescribed by a statute, when there are other concurring elements which show that his course was entirely justifiable.
As a general rule, in deciding a question in relation to negligence, each element which enters as a factor into one’s act to give it character is to be considered in connection with every other, and the result is reached by considering all together. But, for reasons which will presently appear, illegal conduct of a plaintiff directly contributing to the occurrence on which his action is founded, is an exception to this rule. Such illegality may be viewed in either of two aspects: looking at the transaction to which it pertains as a whole, it may be considered as a circumstance bearing upon the question whether there was actual negligence; or looking at it simply in reference to the violated law, the act may be tried solely by the test of that law. In the latter aspect it wears a hostile garb, and an inquiry is at once suggested, whether the plaintiff, as a transgressor of the law, is in a position to obtain relief at the hand of the law. In the first view, the illegal conduct comes within the general rule just stated; in the second, it does not. This distinction has not always been observed. A plaintiff’s violation of law has usually been discussed in connection with the subject of due care.
In Bosworth v. Swansey, 10 Met. 363, Chief Justice Shaw, after referring to the rule that a plaintiff must be free from “imputation of negligence or fault,” says, in reference to unlawful travelling on the Lord’s day, “This would be a species of fault on his part, which would bring him within the principle of the cases cited.”
In Jones v. Andover, 10 Allen, 18, Chief Justice Bigelow says, “The term ‘due care,’ as usually understood, in cases where the gist of the action is the negligence of the defendant, implies not only that a party has not been negligent or careless, but that he has been guilty of no violation of law in relation to the subject-matter or transaction which constitutes the cause of action.”
In Steele v. Burkhardt, 104 Mass. 59, an action for negligence in driving against the plaintiffs’ horse, which was left standing in a street in violation of an ordinance, Chief Justice Chapman considers the general subject of the plaintiffs’ due care, and then treats particularly the contention of the defendant that the plaintiffs were compelled to prove their violation of law in order to establish their case.
McGrath v. Merwin, 112 Mass. 467, was an action founded on the defendant’s alleged negligence in starting the machinery of a mill, while the plaintiff was at work in the wheel-pit making repairs on the Lord’s day, and Mr. Justice Morton, in delivering the opinion, deals with the case solely upon the principle that Courts will not aid a plaintiff whose action is founded upon his own illegal act, and says, “The decisions in this Commonwealth are numerous and uniform to the effect that the plaintiff, being engaged in a violation of law, cannot recover, if his own illegal act was an essential element of his case as disclosed upon all the evidence.” He further states the rule in such cases to be, that, “if the illegal act of the plaintiff contributed to his injury, he cannot recover; but though the plaintiff at the time of the injury was acting in violation of law, if his illegal act did not contribute to the injury, but was independent of it, he is not precluded thereby from recovering.”
In Davis v. Guarnieri, 45 Ohio St. 470, Owen, C. J., states, as the second of three considerations upon which the doctrine of contributory negligence is founded, “the principle which requires every suitor who seeks to enforce his rights or redress his wrongs to go into court with clean hands, and which will not permit him to recover for his own wrong.”
No case has been brought to our attention, and upon careful investigation we have found none, in which a plaintiff whose violation of law contributed directly and proximately to cause him an injury has been permitted to recover for it; and the decisions are numerous to the contrary. Hall v. Ripley, 119 Mass. 135; Banks v. Highland Street Railway, 136 Mass. 485; Tuttle v. Lawrence, 119 Mass. 276, 278; Lyons v. Desotelle, 124 Mass. 387; Heland v. Lowell, 3 Allen, 407; Steele v. Burkhardt, 104 Mass. 59; Damon v. Scituate, 119 Mass. 66; Marble v. Ross, 124 Mass. 44; Smith v. Boston & Maine Railroad, 120 Mass. 490. And it is quite immaterial whether or not a plaintiff’s unlawful act contributing to his injury is negligent or wrong when considered in all its relations. He is precluded from recovering on the ground that the Court will not lend its aid to one whose violation of law is the foundation of his claim. Hall v. Corcoran, 107 Mass. 251.
While this principle is universally recognized, there is great practical difficulty in applying it. The best minds often differ upon the question whether, in a given case, illegal conduct of a plaintiff was a direct and proximate cause contributing with others to his injury, or was a mere condition of it; or, to state the question in another way, appropriate to the reason of the rule, whether or not his own illegal act is an essential element of his case as disclosed upon all the evidence. Upon this point it is not easy to reconcile the cases. It has been unanimously decided that in Gregg v. Wyman, 4 Cush. 322, there was error in holding a plaintiff’s illegal conduct to be an essential element of his case, when in fact it was merely incidental to it. Hall v. Corcoran, ubi supra. But whatever criticisms may have been made upon the decisions or the assumptions in certain cases, that illegal action of a plaintiff contributed to the result, or was to be treated as a concurring cause, or upon language in disregard of the distinction between a cause and a condition, there has been none upon the doctrine that, when a plaintiff’s illegal conduct does directly contribute to his injury, it is fatal to his recovery of damages. Baker v. Portland, 58 Maine, 199; Norris v. Litchfield, 35 N. H. 271; Sutton v. Wauwatosa, 29 Wis. 21.
