A former New York City Department of Finance attorney under investigation for illegally maintaining a private practice and preparing tax and real estate documents that were submitted by his clients to his own department has successfully contested a subpoena issued against him by the Department of Investigation.

A unanimous Appellate Division, 1st Department, panel granted the lawyer’s motion to quash, holding that the only potentially discoverable documents in the otherwise overbroad subpoena are protected by his right against compelled testimony.
