Eleanor and Franklin Johnson filed wrong-fill death and survival actions against Washington Metropolitan Area Transit Authority (WMATA) for the death of their daughter, Devora Johnson, who, on March 20, 1986, jumped onto the tracks before an oncoming train. It is undisputed that by jumping onto the tracks Devora Johnson intended to commit suicide. However, her death could have been avoidеd if the train conductor had not delayed in engaging the emergency brake to stop the train. At issue is whether Devora Johnson’s suicidal intention as a matter of law relieved WMATA of responsibility for the train operator’s tortious conduct under the doctrine of last clear chance. 1
The Circuit Court for the District of Columbia, concluding that a question of District of Columbia law was determinative of the issue and that no controlling precedent existed in the decisions of this court certified to this court 2 the following question:
Under District of Columbia law, and upon the facts described below, may a plaintiff who has voluntarily assumed an unreasonable risk of incurring a particular injury recover from a defendant who failed to take the last clear chance to prevent that injury?
Johnson v. Washington Metro. Area Transit Auth.,
*407 The question certified by the Circuit Court is phrased in terms of whether a plaintiff who has “voluntarily assumed an unreasonable risk” can benefit from the last clear chance doctrine. The question involves the two sometimes distinct, sometimes overlapping, theories of contributory negligence and assumption of risk. Before applying them to the facts of this case, we briefly describe their different origins and relevant District of Columbia ease law.
Contributory Negligence and the Doctrine of Last Clear Chance
In the District of Columbia, a plaintiff whose negligence contributes to his or her injury may not recover from a negligent defendant unless the defendant had the last clear сhance to avoid injuring the plaintiff.
Felton v. Wagner,
(1) that the plaintiff was in a position of danger caused by the negligence of both plaintiff and defendant; (2) that the plaintiff was oblivious to the dаnger, or unable to extricate herself from the position of danger; (3) that the defendant was aware, or by the exercise of reasonable care should have been aware, of the plaintiff’s danger and of her oblivion to it or her inability to extricate herself from it; and (4) that the defendant, with means available to him, could have avoided injuring the рlaintiff after becoming aware of the danger and the plaintiff’s inability to extricate herself from it, but failed to do so.
Felton, supra,
The doctrine of last clear chance has been characterized as a transitional doctrine, preparing the way for a system of comparative negligence. See Malcolm M. MacIntyre, The Rationale of Last Clear Chance, 53 HaRV. L.Rev. 1225 (1940); Fleming James, Jr., Last Clear Chance: A Transitional Doctrine, 47 Yale L.J. 704 (1938). Various justifications have been offered for the last clear chance doсtrine. One common explanation is that the plaintiff’s negligence was not the proximate cause of the harm because the defendant had the last opportunity to prevent it. See J.D. Lee & Baery A. Lindahl, Modern Tort Law § 11.07, at 327 (Rev. ed. 1989) (“[T]he doctrine is based on the notion that the last proximate cause of the injury is the real and legal cause.”); Restatement (Second) of Torts § 479 cmt. a (1965); 4 but see W. Page Keeton et al., Prosser and Keeton on the Law of Torts § 66, at 463 (5th ed.1984) (noting that this explanation runs contrary to the “evolving ideas of proximate cause”). Another justification involves an assessment of relative fault where “the later negligence of the defendant involves a higher degree of fault_” Keeton et al., supra, at 463. This justifiсation is especially applicable to situations where the defendant acts recklessly or intentionally or where the defendant has discovered a helpless plaintiff. Id. (noting that this rationale cannot explain other situations where “the defendant’s fault consists merely in a failure to discover the *408 danger at all, or in slowness, clumsiness, inadvertеnce or an error in judgment in dealing with it” (footnote omitted)). 5 Perhaps the real justification for the rule is “a fundamental dislike for the harshness of the contributory negligence defense,” Keeton et al., swpra, at 464, which would explain why it seems particularly apt in situations where the defendant’s negligence is seen “as the final and decisive factor in producing the injury.” Restatement, supra, § 479 cmt. a.
Assumption of Risk
Assumption of risk, like contributory negligence, relieves a negligent defendant of liability. It is a complete defense to a claim of negligence “under a theory of “waiver’ or ‘consent’ ” proceeding from the premise that a person, after evaluating a situation, has voluntarily decided to take a known risk.
Sinai v. Polinger Co.,
The doctrine of last clear chance is apрlied in cases where a defense of contributory negligence has been raised, and does not apply if the sole defense is that the injured party assumed the risk. Lee
&
Lindahl,
supra,
at 244. Both defenses, however, may be asserted in the same ease arising from a single set of facts, e.g., where a plaintiff initially assumes the risk and subsequently acts negligently. Although the two defensеs are “closely related ... we have consistently maintained that the two defenses are separate and distinct_”
Morrison, supra,
Suicides
We consider the certified question “upon the facts” of this case, a suicide, that was characterized as constituting both contributory negligence and assumption of risk. 6 Keeping in mind the principles underlying the two doctrines, we turn to consider whether, under District of Columbia law, Ms. Johnson’s suicidal intent constituted assumption of risk that barred recovery for WMA-TA’s negligence or whether WMATA may be held liable under the doctrine of last clear chance for its failure to avoid the fatal consequences of Ms. Johnson’s suicide. Our answer was anticipated by Judge Mikva in Johnson I, when he concluded that, without any indicаtion to the contrary, he was “unprepared to assume that the District of Columbia Court of Appeals would carve out a suicide exception from its long-established last clear chance doctrine.” Johnson I, supra note 3, 280 U.S.App. D.C. at 59, 883 F.2d *409 at 181. We confirm that District of Columbia law does not except suicides from the last clear chance doctrine.
We come to this cоnclusion from two perspectives. First, as the court in
Johnson I
noted, there is no case law in the District of Columbia which supports a suicide exception to the last clear chance doctrine, and “the D.C. courts [have not] given any indication that such an exception would be found if a case properly presented the issue.” Id at 58,
Second, we are unprepared to hold that a person intending suicide, as a matter of law, always “assumes the risk” of death, as that defense has developed in the law to bar recovery for negligent acts. The requirements of knowledge and voluntariness, implying reasonable decision-making, that un-dergird the waiver and consent principles of assumption of risk do not comfortably fit a suicide, particularly on the facts of this ease. Here, Ms. Johnson, the mother of a young child, chose a public venue for a most violent death. Evidence presented at trial in this case showed that Ms. Johnson had a history of serious mental illness, including seven hospitalizations.
Johnson I, supra
note 3,
We are unpersuaded by the argument that our holding today will provide an incentive for individuals to commit suicide in the hope that their estates will benefit. That policy argument is purely speculative. No study or judicial finding has been offered in support of the proposition that suicides will be encouraged if the last clear chancе doctrine is available in cases involving suicides. There is nothing in the record of the ease before us indicating that Ms. Johnson sought death in order to benefit her estate. Before changing established doctrine on policy grounds, we require persuasive evidence in support of the proffered policy argument.
Moreover, we believe that thе burden of proving the four factors necessary to prevail under the last clear chance doctrine already provides a significant barrier to recovery.
See Felton, supra,
We believe that application of the doctrine of last clear chance to the facts before us on this certified question squares with the objective of negligence law, “that one whose act unintentionally causes injury to another is generally liable to compensate the other only if the act was not reasonable under the circumstances — that is, only if the act created a foreseeable risk that could have been mitigated at a cost not disproportionate in light of the gravity and probability of the fоreseeable harm.”
Ray v. American Nat’l Red Cross,
So ordered.
Notes
. The question presented by this case is distinguishable from that presented in
District of Columbia v. Peters,
. D.C.Code § 1 l-723(a) provides:
The District of Columbia Court of Appeals mаy answer questions of law certified to it by the Supreme Court of the United States, a Court of Appeals of the United States ... if there are involved in any proceeding before any such certifying court questions of law of the District of Columbia which may be determinative of the cause pending in such certifying court and as to which it appears to the certifying court there is no controlling precedent in the decisions of the District of Columbia Court of Appeals.
.This case has had a considerable history in the federal courts leading up to this certification. Briefly, in
Johnson v. Washington Metro. Area Transit Auth.,
. The Restatement (Second) of Torts § 479 comment a states:
[T]he plaintiffs nеgligence is not a “proximate" or legal cause of the harm to him, because the later negligence of the defendant is a superseding cause which relieves the plaintiff of responsibility for it.
. According to the Restatement, a commonly given explanation is that:
[T]he later negligence of the defendant involves a higher degree of fault. This mаy be true in cases where the defendant has discovered the danger and his conduct approaches intentional or reckless disregard of it....
Restatement (Second) of Torts § 479 cmt. a.
. In this case, the jury was instructed that:
when Miss Johnson intentionally jumped from the train platform on to the tracks this act constituted contributory negligence on her part. You are also instructed that she was aware of and able fully to appreciate the risk that her jump on to the tracks entailed.
. Under these circumstances we need not consider whether a suicidal intent may never, as a matter of law, come within the contemplation of informed and voluntary risk-taking inherent in the doctrine of assumption of risk such that it would 'waive' the defendant’s responsibility to act reasonably to prеvent the suicide.
. In this case where Ms. Johnson had the legal status of a trespasser, the Johnsons had the additional burden of proving that WMATA acted intentionally, willfully or wantonly.
