Sources and Authority

Restatement Second of Torts, section 315 states:

As a general rule, one owes no duty to control the conduct of another, nor to warn those endangered by such conduct. Such a duty may arise, however, if

(a)a special relation exists between the actor and the third person which imposes a duty upon the actor to control the third person’s conduct, or

(b)a special relation exists between the actor and the other which gives the other a right of protection.

The Supreme Court has held that “[t]he relationship between a common carrier and its passengers is … a special relationship.” (Lopez v. Southern Cal. Rapid Transit Dist. (1985) 40 Cal.3d 780, 789 [221 Cal.Rptr. 840, 710 P.2d 907].)

The common carrier standard of “utmost care” applies to the duty of a carrier to protect a passenger from assaults by fellow passengers. (Terrell v. Key System (1945) 69 Cal.App.2d 682, 686 [159 P.2d 704].) However, the duty can only arise if “in the exercise of the required degree of care the carrier has or should have knowledge of conditions from which it may reasonably be apprehended that an assault on a passenger may occur, and has the ability in the exercise of that degree of care to prevent the injury.” (Ibid., internal citations omitted.)

The Lopez court stated the standard of care as follows: “[C]arriers are not insurers of their passenger’s safety and will not automatically be liable, regardless of the circumstances, for any injury suffered by a passenger at the hands of a fellow passenger. Rather, a carrier is liable for injuries resulting from an assault by one passenger upon another only where, in the exercise of the required degree of care, the carrier has or should have knowledge from which it may reasonably be apprehended that an assault on a passenger may occur, and has the ability in the exercise of that degree of care to prevent the injury.” (Lopez, supra, 40 Cal.3d at p. 791, internal citation omitted.)

There is no liability when a sudden assault occurs with no warning. (City and County of San Francisco v. Superior Court (1994) 31 Cal.App.4th 45, 49 [36 Cal.Rptr.2d 372].)
