Principle 2 : In all cases of bailment the bailee is bound to take as much care of the goods bailed to him/her as a person of ordinary prudence would, under similar circumstances, take of his/her own goods of the same bulk, quantity and value as the goods bailed.
Facts : Aparna entered into a contract with Gagan to keep her goods in his warehouse until she was able to find a suitable buyer for them. Gagan kept his own goods also at the same warehouse. One night, certain thieves entered the warehouse and stole the goods of both Gagan and Aparna. It was discovered that even though Gagan had locked the main door, he had carelessly left the windows open and that the thieves had entered through the open windows. Aparna sued Gagan for damages as Gagan had failed to take due care of her goods. Decide.
