2. Question:Why does the Noda BiYehuda hold that if a person dies on Pesach and he had not nullified or gotten rid of his chometz why is the chometz permitted after Pesach if the Rabbis decreed in general a fine for any chometz in the possession of someone during Pesach is forever forbidden after Pesach?
A. The Mishna Berura (435:1:3) says that a father does not bequeath to his children prohibition, however the father owned it in a prohibitive state at the beginning of Pesach before he died.
B. Hint: When does the fine go into effect?
Answer: The chometz is not forbidden because of the dead father because the fine only ges into effect after Pesach and since he died beforehand the fine wasn’t enacted on him, nor was it enacted on his children since they did not commit any sin. (See Dirshu Mishna Berura there, footnote 7)
