The respondents, a husband and wife, sued the appellant bank for damages arising from the theft of the contents of a safe deposit box hired by the first respondent at the bank’s Auckland Park branch. The safe deposit box and its contents were stolen in October 1996. It was assumed for purposes of a stated case that one or more bank employees either stole the box themselves or negligently (or grossly negligently) failed to control the keys safeguarding the vault, thereby enabling the theft, and that such employees acted within the course and scope of their employment. The bank relied on clause 2 of the standard safe deposit box agreement, which purported to exclude liability for loss or damage caused by theft or negligence, to avoid liability.
