  1. Reuven arrived in Shul to pray, and removed his glasses and placed them on an empty chair that was next to him. Shimon, who arrived a little later than Reuven, did not notice the glasses and sat down on them, and broke the glasses.

    Is Shimon Halachically obligated to pay Reuven for the broken glasses?

  2. Reuven used a glass cup owned by the Shul to have a glass of tea while he was studying. After finishing the tea, Reuven placed the glass cup on an empty chair. Shimon did not notice the glass, and sat down on the Chair, causing the glass to fall to the floor and break.

    Who is responsible to pay the Shul for the broken glass?


  1. In both of the above situations, Shimon would not be liable for the damage that he had unintentionally caused. This is true even if he usually sat in another seat in the Shul, and just this once decided to sit next to Reuven.

    However, this is only because Shimon had no knowledge of the items at all at the time that he sat down. If he had seen them but had forgotten that they were there and sat on them, he would be obligated to compensate Reuven (in Question A) and the Shul (in Question B).

  2. Regarding Reuven’s liability, in Question B he would be obligated to pay the Shul for not properly caring for the Shul’s property. In Question A, since he is the owner of the glasses, he caused his own loss by placing them on the chair.


The Mishna in Bava Kamma (2:6) states that “Odom Muad L’Olam”, a person is responsible for damages caused by his actions even if done unintentionally. However, the Gemara there (27b) quotes a statement of Ulla that it is not customary for a person to constantly check the path that he is walking on to make sure that he won’t damage someone else’s item that may be in the way. Therefore, if someone were to unintentionally damage someone else’s item that is in his way as he is walking, he would not have to pay for this item.

Tosafos there (D’H U’Shmuel) explain the above distinction made by Ulla as follows. Although a person is held responsible even for unintentional damages, this is only if the damage could have been prevented if the person had exercised a little more care. Tosafos call this “Onnus K’Ein Aveidah”, unintentional damage that is similar to losing something. Just as the loss of an item can generally be prevented with a little foresight, so too for a person to be liable for damages it must be damage that could have been prevented with a little foresight. However, this is only where it is expected for people to act with caution. Since, generally, people are not cautious of what may be in their paths as they walk along, there would be no liability in such a case.

Consequently, in the two cases discussed in our question, if Shimon did not notice the glasses or the cup on the chair before sitting down, since it is not customary for people to keep breakable things on chairs in the synagogue, Shimon can argue that there was no negligence on his part at all, since it would be similar to something laying in his path, for which he has no liability, as per the statement of Ulla.

However, if Shimon did notice the glasses on the chair, but forgot that they were there and ended up sitting on them accidentally, Reuven can argue that the damage was a result of a small degree of negligence on Shimon’s part, and he would be liable. He should have moved them immediately upon noticing them to insure that he would not break them. Although Reuven may have acted improperly by placing them on the chair, that does not mean that he is giving people license to damage him. Therefore, Shimon’s actions are considered “Onnus K’Ein Aveidah”, and he will be responsible for damages as stated in the Mishna.

The Nesivos Mishpat (Siman 291:7,14) and the K’tzos HaChoshen (319:3) both state that although a person can not be held liable in Bais Din for damage that indirectly resulted from his actions (Gramma B’Nizakin), if you were to move someone else’s item from a place where it is protected from damage or theft to a place where it will now be exposed, and it was damaged as a result of this, this is considered as if you directly damaged it and you are obligated to pay for the item. Therefore, in Question B, although Shimon can not be held responsible for the damage if he was totally unaware that the cup was there, Reuven can be held responsible for placing the Shul’s property in a spot where it is exposed to damage. Therefore, he will be obligated to compensate the Shul for loss of it’s property. However, in a case that Shimon is held liable for damages, i.e. he was aware of the potential to damage but did not exercise foresight, the liability is solely Shimon’s, and Reuven has no responsibility at all. [Proof of this may be found in Tosafos in Bava Kamma 30a (D’H V’Chayav Baal HaKosel). See also the Nimukei Yosef there, particularly his quote from the Ramah.]
