care [is] always related to ‘some circumstance of time, place and person’ [citation].” (United States Liab. Ins. Co. v. Haidinger-Hayes, Inc. (1970) 1 Cal.3d 586, 594 [83 Cal.Rptr. 418, 463 P.2d 770].) The issue with respect to the existence of a duty owed by a defendant to a plaintiff, the breach of which may create liability, is basically a question of law for determination by the court.
“The determination of duty is primarily a question of law. [Citation.] It is the court’s ‘expression of the sum total of those considerations of policy which lead the law to say that the particular plaintiff is entitled to protection.’ [Citation.] Any number of considerations may justify the imposition of duty in particular circumstances, including the guidance of histoiy, our continually refined concepts of morals and justice, the convenience of the rule, and social judgment as to where the loss should fall. [Citation.] While the question whether one owes a duty to another must be decided on a case-by-case basis, every case is governed by the rule of general application that all persons are required to use ordinary care to prevent others from being injured as the result of their conduct. [Citation.]” (Fn. omitted.) (Weirum v. RKO General, Inc. (1975) 15 Cal.3d 40, 46 [123 Cal.Rptr. 468, 539 P.2d 36].)
A primary consideration in establishing the element of duty is the foreseeability of the risk, even though foreseeability is a question of fact for the jury. (See Weirum, supra, 15 Cal.3d 40, at p. 46; Dillon v. Legg (1968) 68 Cal.2d 728 [69 Cal.Rptr. 72, 441 P.2d 912, 29 A.L.R.3d 1316].) The California Supreme Court has summarized the principal policy considerations in establishing the existence of duty as follows: “[T]he major ones are the foreseeability of harm to the plaintiff, the degree of certainty that the plaintiff suffered injury, the closeness of the connection between the defendant’s conduct and the injury suffered, the moral blame attached to the defendant’s conduct, the policy of preventing future harm, the extent of the burden to the defendant and consequences to the community of imposing a duty to exercise care with resulting liability for breach, and the availability, cost, and prevalence of insurance for the risk involved. [Citations.]” (Rowland v. Christian (1968) 69 Cal.2d 108, 113 [70 Cal.Rptr. 97, 443 P.2d 561, 32 A.L.R.3d 496].)
The duty one owes to conduct oneself with due care, however, is quite different from the duty that one may owe to control the conduct of another. A recent decision of the California Supreme Court tells us that “[although . . . under the common law, as a general rule, one person
