Vitaly TARASOFF et al., Plaintiffs and Appellants,
v.
THE REGENTS OF THE UNIVERSITY OF CALIFORNIA et al., Defendants and Respondents
Supreme Court of California
17 Cal. 3d 425; 551 P.2d 334 (1976)
Tobriner, J. On October 27, 1969, Prosenjit Poddar killed Tatiana Tarasoff. Plaintiffs, Tatiana's parents,
allege that two months earlier Poddar confided his intention to kill Tatiana to Dr. Lawrence Moore, a
psychologist employed by the Cowell Memorial Hospital at the University of California at Berkeley. They allege
that on Moore's request, the campus police briefly detained Poddar, but released him when he appeared rational.
They further claim that Dr. Harvey Powelson, Moore's superior, then directed that no further action be taken to
detain Poddar. No one warned plaintiffs of Tatiana's peril. ***
Plaintiffs' complaints predicate liability on two grounds: defendants' failure to warn plaintiffs of the
impending danger and their failure to bring about Poddar's confinement pursuant to the Lanterman-Petris-Short
Act (Welf. & Inst. Code, @ 5000 ff.) Defendants, in turn, assert that they owed no duty of reasonable care to
Tatiana and that they are immune from suit under the California Tort Claims Act of 1963 (Gov. Code, @ 810
ff.). ***
We shall explain that defendant therapists cannot escape liability merely because Tatiana herself was not
their patient. When a therapist determines, or pursuant to the standards of his profession should determine, that
his patient presents a serious danger of violence to another, he incurs an obligation to use reasonable care to
protect the intended victim against such danger. The discharge of this duty may require the therapist to take one
or more of various steps, depending upon the nature of the case. Thus it may call for him to warn the intended
victim or others likely to apprise the victim of the danger, to notify the police, or to take whatever other steps are
reasonably necessary under the circumstances. ***
In the case at bar, plaintiffs admit that defendant therapists notified the police, but argue on appeal that
the therapists failed to exercise reasonable care to protect Tatiana in that they did not confine Poddar and did not
warn Tatiana or others likely to apprise her of the danger. Defendant therapists, however, are public employees.
Consequently, to the extent that plaintiffs seek to predicate liability upon the therapists' failure to bring about
Poddar's confinement, the therapists can claim immunity under Government Code section 856. No specific
statutory provision, however, shields them from liability based upon failure to warn Tatiana or others likely to
apprise her of the danger, and Government Code section 820.2 does not protect such failure as an exercise of
discretion. ***
The second cause of action can be amended to allege that Tatiana's death proximately resulted from
defendants' negligent failure to warn Tatiana or others likely to apprise her of her danger. Plaintiffs contend that
as amended, such allegations of negligence and proximate causation, with resulting damages, establish a cause of
action. Defendants, however, contend that in the circumstances of the present case they owed no duty of care to
Tatiana or her parents and that, in the absence of such duty, they were free to act in careless disregard of
Tatiana's life and safety. ***
In analyzing this issue, we bear in mind that legal duties are not discoverable facts of nature, but merely
conclusory expressions that, in cases of a particular type, liability should be imposed for damage done.***
Although, *** under the common law, as a general rule, one person owed no duty to control the conduct
of another, *** nor to warn those endangered by such conduct, *** the courts have carved out an exception to
this rule in cases in which the defendant stands in some special relationship to either the person whose conduct
needs to be controlled or in a relationship to the foreseeable victim of that conduct ***
Although plaintiffs' pleadings assert no special relation between Tatiana and defendant therapists, they
establish as between Poddar and defendant therapists the special relation that arises between a patient and his
doctor or psychotherapist. Such a relationship may support affirmative duties for the benefit of third persons.
Thus, for example, a hospital must exercise reasonable care to control the behavior of a patient which may
endanger other persons. A doctor must also warn a patient if the patient's condition or medication renders
certain conduct, such as driving a car, dangerous to others.
Although the California decisions that recognize this duty have involved cases in which the defendant
stood in a special relationship both to the victim and to the person whose conduct created the danger, we do not
think that the duty should logically be constricted to such situations. Decisions of other jurisdictions hold that
the single relationship of a doctor to his patient is sufficient to support the duty to exercise reasonable care to
protect others against dangers emanating from the patient's illness. The courts hold that a doctor is liable to
persons infected by his patient if he negligently fails to diagnose a contagious disease *** or, having diagnosed
the illness, fails to warn members of the patient's family ***.
Defendants contend, however, that imposition of a duty to exercise reasonable care to protect third
persons is unworkable because therapists cannot accurately predict whether or not a patient will resort to
violence. In support of this argument amicus representing the American Psychiatric Association and other
professional societies cites numerous articles which indicate that therapists, in the present state of the art, are
unable reliably to predict violent acts; their forecasts, amicus claims, tend consistently to overpredict violence,
and indeed are more often wrong than right. Since predictions of violence are often erroneous, amicus
concludes, the courts should not render rulings that predicate the liability of therapists upon the validity of such
predictions. ***
We recognize the difficulty that a therapist encounters in attempting to forecast whether a patient
presents a serious danger of violence. Obviously, we do not require that the therapist, in making that
determination, render a perfect performance; the therapist need only exercise "that reasonable degree of skill,
knowledge, and care ordinarily possessed and exercised by members of [that professional specialty] under similar
circumstances."
In the instant case, however, the pleadings do not raise any question as to failure of defendant therapists
to predict that Poddar presented a serious danger of violence. On the contrary, the present complaints allege that
defendant therapists did in fact predict that Poddar would kill, but were negligent in failing to warn.
Amicus contends, however, that even when a therapist does in fact predict that a patient poses a serious
danger of violence to others, the therapist should be absolved of any responsibility for failing to act to protect the
potential victim. In our view, however, once a therapist does in fact determine, or under applicable professional
standards reasonably should have determined, that a patient poses a serious danger of violence to others, he bears
a duty to exercise reasonable care to protect the foreseeable victim of that danger. ***
The risk that unnecessary warnings may be given is a reasonable price to pay for the lives of possible
victims that may be saved. We would hesitate to hold that the therapist who is aware that his patient expects to
attempt to assassinate the President of the United States would not be obligated to warn the authorities because
the therapist cannot predict with accuracy that his patient will commit the crime.
Defendants further argue that free and open communication is essential to psychotherapy. *** The giving of a
warning, defendants contend, constitutes a breach of trust which entails the revelation of confidential
communications.
We recognize the public interest in supporting effective treatment of mental illness and in protecting the
rights of patients to privacy (see In re Lifschutz, supra, 2 Cal.3d at p. 432), and the consequent public importance
of safeguarding the confidential character of psychotherapeutic communication. Against this interest, however,
we must weigh the public interest in safety from violent assault. The Legislature has undertaken the difficult task
of balancing the countervailing concerns. In Evidence Code section 1014, it established a broad rule of privilege
to protect confidential communications between patient and psychotherapist. In Evidence Code section 1024,
the Legislature created a specific and limited exception to the psychotherapist-patient privilege: "There is no
privilege . . . if the psychotherapist has reasonable cause to believe that the patient is in such mental or emotional
condition as to be dangerous to himself or to the person or property of another and that disclosure of the
communication is necessary to prevent the threatened danger." ***
Our current crowded and computerized society compels the interdependence of its members. In this risk-infested society we can hardly tolerate the further exposure to danger that would result from a concealed knowledge of the therapist that his patient was lethal. If the exercise of reasonable care to protect the threatened victim requires the therapist to warn the endangered party or those who can reasonably be expected to notify him, we see no sufficient societal interest that would protect and justify concealment. The containment of such risks lies in the public interest. For the foregoing reasons, we find that plaintiffs' complaints can be amended to state a cause of action against defendants Moore, Powelson, Gold, and Yandell and against the Regents as their employer, for breach of a duty to exercise reasonable care to protect Tatiana.
