Although the lawsuit brought by YAFFED against the Felder Amendment — legislation which allows chareidi schools in New York State to determine for themselves if their curricula meets state-mandated equivalency requirements — has been dismissed, readers shouldn’t miss out on some of the valuable material in the legal papers submitted in the case. One of these is an eight-page declaration submitted to the federal judge presiding over the case by Professor Awi Federgruen. The Charles E. Exley Professor and Chair of the Decision, Risk and Operations Division at Columbia Business School, he’s an expert in the area of applied probability and has edited some of the field’s leading professional journals.
