I am sorry to bring you the news that Boris Kostelanetz, the "dean of tax defense lawyers," has died at age 94.  From the New York Times obituary:

Mr. Kostelanetz, a founding partner of Kostelanetz & Fink, handled the defense in tax evasion cases for scores of well-known clients like Imelda Marcos and James Brown….

During his long career, Mr. Kostelanetz handled a heavy load of tax evasion cases. Among the clients he defended were Bobby Baker, a protégé of President Lyndon B. Johnson; Dr. W. Kenneth Riland, the physician to President Richard M. Nixon and Gov. Nelson A. Rockefeller; and Anthony Conrad, chairman of the RCA Corporation. His efforts were frequently successful.
