Jewish Business School Case Studies For a Test on Lessons 15-21

1. Rob infects Jack’s computer with a virus. Jack claims that he incurred a financial loss and claims compensation from Rob in a Jewish court. Clearly, the Torah was written thousands of years ago and does not discuss digital damages. What method can the judges use to begin thinking about what Jewish law says about this issue?

2. What is the defining characteristic of the primary category of damage known as “Fire”? In what way might this be relevant to damage via a computer virus?

3. Rob infects Jack’s computer with a virus by sending him an email with an infected attachment. Rob claims that he can’t be liable for damages since on a technical level he did not actually damage Jack’s computer since Jack could have deleted the email. In fact, Rob claims that it was Jack who brought the damage on himself by clicking on the attachment. What would a judge say in such a case?

4. If David lends Noah 100$ then Noah should pay him back 100$. However, according to Jewish law, if David lends Noah 100 apples then Noah cannot pay back 100 apples at a later date. Why not?

5. Jewish law differentiated between “currency” and “commodity” for a variety of issues. Does paper money have the status of a currency or a commodity? Why or why not?

6. David lends Noah 2 Bitcoins on January 1st , when they are worth 100,000$. When the time comes for Noah to pay back the loan, the value of 2 Bitcoins is 80,000$. Can Noah just pay 2 Bitcoins at the value of 80,000$ or must be pay Noah 100,000$ based on the value of the bitcoins at the time of the loan? What is the rationale for this ruling?

7. Please explain the meaning of “kinyan situmta” (literal translation: “acquiring an object via putting a stamp on it”).

8. In the diamond district of New York City, it is common to diamond merchants to finalize a deal with a handshake (even though the diamonds or the money are not present and have not transferred hands). Does this constitute a halachik acquisition? Have the diamonds legally changed ownership at this point?

9. Does clicking on “buy” for an online purchase legally give you ownership over an item? Please briefly explain why or why not.

10. If Sara hires Abigail for a job and does not stipulate a termination date, is Sara allowed to fire Abigail at will?

11. Even if we assume that an employer can fire his/her employee at will (if there is no contract stipulating the duration of employment), are there are any moral reasons for an employer to retain an employee? If yes, what are these reason(s)?

12. Does Jewish law have a concept of severance pay for an employee who is laid off?

13. Am I allowed to “borrow” someone else’s item without permission and return it later that day?

14. Please explain the concept of “kofin al middat sedom” (“we compel people to not act like the people of Sedom.”)

15. Rabbi Hershel Schachter, a leading authority of Jewish law who teaches at Yeshiva University, was asked about a person who bought tickets at a sports game, but noticed that there was an open seat in a more expensive section. Can the person move to the open seat? What was his response and why?

16. Is one permitted to steal as a joke, if he/she fully intends to return the item afterwards?

17. If it is not permitted to take something that does not belong to you, even with the intention of returning it, why is it common practice for teachers to confiscate items that students are playing with in class?

18. A teacher confiscates an item and leaves it in an unlocked closet in the school overnight. The item is stolen from the closet. Must the teacher compensate the student for the item?

19. If one builds a sukkah on the sidewalk without permission from local authorities, is it a valid sukkah for Sukkot?

20. What is the meaning of the phrase “Dina D’malchusa Dina” (“The Law of the Land is the Law”)?

21. We know that Jewish law requires us to be law abiding citizens. Let us say that one is traveling on a highway with a speed limit of 55 mph. Is it against Jewish law to travel at 56 mph? Why or why not?
