Someone received permission from his friend to leave his bicycle left in his friend’s locked yard. The yard – which is normally locked – was left unlocked by the homeowner on Rosh Hashana and then stolen. Is the property owner obligated in any way to pay for the stolen bicycle?
Sorry to hear. This seems to be a case of a peshiya (negligence), in which case the property owner will be obligated to pay the value of the bicycle.
I think the regular way to keep a bicycle is specifically in a locked yard, and this is the more so true if the premise of leaving the bicycle there was that the yark would be locked.
Note that the parties would have to go together to a rabbi or a Beis Din in order for the ruling to be binding on him.
