What is the test for reasonable foreseeability in the context of negligence liability?

6 Dillon did not view reasonable foreseeability only as a general test for negligence liability but as a consideration of " 'primary importance in establishing the element of duty.' [Citations.]" (Dillon v. Legg, supra, 68 Cal.2d at p. 739, 69 Cal.Rptr. 72, 441 P.2d 912, italics added.)

7 Case law indicates that the remaining considerations are not alternative bases for a finding of duty where foreseeability is absent. Rather, they come into play where foreseeability is present, but there is an issue as to whether foreseeability alone is sufficient to warrant imposition of liability. (See Parsons v. Crown Disposal Co., supra, 15 Cal.4th at p. 476, 63 Cal.Rptr.2d 291, 936 P.2d 70.)
