Geordie – I have a question for you. If the Rosh Yeshiva decides that his responsibility for the financial support of the yeshiva is best met by hiring a professional administrator who can do a better job than him in raising and handling the money, does that mean that he is relinquishing his title of Rosh yeshiva to his employee? I think that is what is being implied on this thread about BMG.
Totally different. In your scenario, the head of the yeshiva is still in charge. The buck stops with him, but he hires an employee to assist. If the employee does a poor job, the owner is still responsible. In the Mir/Lakewood situation, the owner is the one who is the ba’al achrayus and hence the “Rosh Yeshiva”.
