A passenger was injured because a bystander outside the bus hurled a stone. Is the bus company liable?
No. There is no showing that any such incident previously happened so as to impose an obligation on the part of the personnel of the bus company to warn the passengers and to take the necessary precaution. Such hurling of a stone constitutes fortuitous event in this case. The bus company is not an insurer of the absolute safety of its passengers. (Pilapil v. CA, G.R. No. 52159, Dec. 22, 1989) (1994 Bar Question)
