Answer:
As a responsible employee who has signed a confidentiality agreement, it is important to uphold the agreement and maintain the confidentiality of all cases at hand. Therefore, I would explain to my friend that I am unable to provide any documents or information regarding the case due to the confidentiality agreement I have signed. I would also advise my friend to seek legal counsel and follow the proper legal procedures to obtain any necessary documents or information. It is important to maintain professional ethics and integrity in such situations to avoid any legal or ethical complications.
