Tarasoff v. Regents of University of Californiared2 sentences2026Appellants argue, for the first time on appeal, there are triable issues under title 42 United States Code section 1983 , the Bane Act under Civil Code section 52.1, Government Code section 815.6, and the failure to warn others under Tarasoff v. Regents of University of California (1976) 17 Cal.3d 425 . 2021(Id. at p. 751.) The court distinguished Tarasoff, supra, 17 Cal.3d 18 425 on the basis that the decedent was not a foreseeable or readily identifiable target of the juvenile’s threats. | 169 | 291 |

Carlin v. Superior Courtgreen2 sentences2024(Id. at 1104-1106.) It instead “defines the scope of a manufacturer’s duty to warn in context of prescription drugs” or medical devices (id. at p. 1104) by providing that the manufacturer’s “duty to warn runs to the physician, not to the patient” (Carlin, supra, 13 Cal.4th at p. 1116 ). 2024In a typical products liability case, a manufacturer owes a duty to warn the end user “about the hazards inherent in their products.” (Johnson v. American Standard, Inc. (2008) 43 Cal.4th 56, 64 .) For manufacturers of prescription drugs and many medical devices, however, the “duty to warn runs to the physician, not to the patient.” (Carlin v.

Department of Corrections & Rehabilitation (2008) 168 Cal.App.4th 231, 245 (Giraldo).) As will be further discussed, while there is generally no duty to come to the aid of another, such certain relationships do give rise to a duty of care. 2010(See Tarasoff v.

Delgado v. Trax Bar & Grillgreen2 sentences2024(Brown v. USA Taekwondo (2021) 11 Cal.5th 204 , 213 (Brown).) As a general rule, a defendant owes a duty of care to “ ‘all persons who are foreseeably endangered by his conduct, with respect to all risks which make the conduct unreasonably dangerous.’ ” (Tarasoff v. Regents of University of California (1976) 17 Cal.3d 425 , 434-435.) To determine whether a duty exists in an ordinary negligence case, courts evaluate “whether the category of negligent conduct at issue is sufficiently likely to result in the kind of harm experienced that liability may appropriately be imposed on the negligent par 2021The same rule applies to a person who stumbles upon a mugging, for “as a general matter, there is no duty to act to protect others from the conduct of third parties.” (Delgado v. Trax Bar & Grill (2005) 36 Cal.4th 224, 235 (Delgado); see also Regents, supra, 4 Cal.5th at p. 619 [Generally, “ ‘one owes no duty to control the conduct of another, nor to warn those endangered by such conduct.’ ”].)5 This general rule, we have explained, “derives from the common law’s distinction between misfeasance and nonfeasance, and its reluctance to impose liability for the latter.” (Tarasoff v.

[Citations.]” (Delgado v. Trax Bar & 2007Code, § 1714.) On the other hand, “[a] person who has not created a peril is not liable in tort merely for failure to take affirmative action to assist or protect another . . . .” (Williams v.

Hedlund v. Superior Courtgreen2 sentences2025For instance, in Hedlund, the plaintiffs’ cause of action for failure to warn came within MICRA because the proper diagnosis of the patient was an element of the plaintiffs’ cause of action. ( Hedlund, supra, 34 Cal.3d at pp. 703-704.) We explained: “Tarasoff [v. Regents of University of California (1976) 17 Cal.3d 425 held] that diagnoses and predictions about the danger of violence presented by a patient must be rendered under accepted rules of professional responsibility, and that in so doing therapists must exercise the ‘ “reasonable degree of skill, knowledge and care ordinarily possessed 2015At a follow-up meeting the next day, Thompson stated he did not have any intent to harm others and denied experiencing any homicidal ideation.9 During subsequent meetings with Green on March 18th, 26th and 8 The Legislature passed Civil Code section 43.92 in response to Hedlund v. Superior Court (1983) 34 Cal.3d 695 and Tarasoff v. Regents of University of California (1976) 17 Cal.3d 425 , which contained broad language suggesting that a therapist owed a duty of care “‘to predict and warn of potential violence by his patient’” (Ewing v.

Stevens v. Parke, Davis & Co.green2 sentences2022As plaintiffs put it, “because manufacturers do not adequately warn doctors, they must warn patients.” 13 In support of their position, plaintiffs point to language in Stevens v. Parke, Davis & Co. (1973) 9 Cal.3d 51 (Stevens), a case in which our Supreme Court discussed the operation of the learned intermediary doctrine, saying this: “[i]n the case of medical prescriptions, ‘if adequate warning of potential dangers of a drug has been given to doctors, there is no duty by the drug manufacturer to insure that the warning reaches the doctor’s patient for whom the drug is prescribed.’ ” (Id. at p 2020(See Webb v. Special Electric Co., Inc. (2016) 63 Cal.4th 167, 179 [“A product can be defective in its manufacture or design, or because it fails to include a warning about known risks.”].) “‘Generally speaking, manufacturers have a duty to warn consumers about the hazards inherent in their products.’” (Id. at p. 181.) In the case of prescription drugs, however, California has adopted the “learned intermediary doctrine,” according to which “‘the duty to warn runs to the physician, not to the patient.’ [Citation.] ‘“[I]f adequate warning of potential dangers of a drug has been given to doctors, | 3 | 7 |

Because the duty to warn is an essential element of plaintiffs’ claims, and the learned intermediary doctrine sets the scope of the duty with respect to the prescription drug amiodarone, it is plaintiffs’ burden to plead and prove that defendants failed to adequately warn the prescribing physician of the potential risks. 2016Thus, the duty to warn in these cases runs to the physician, not the patient."
