He left the United States Department of Justice in 1957 to join his father at Haight, Gardner, Poor & Havens as an associate.
[citation needed] Early the following year, Haight made an unusual provision, when he sentenced John G. Stoessinger, a United Nations official, to teaching prison inmates for failing to report fraud in excess of $260,000.
Haight continued to preside over high-profile cases, including fraud relating to investors at Morgan & Stanley Co. and Lehman Brothers, Kuhn Loeb, Inc. in 1982, insider trading at Dean Witter Reynolds in 1984, police surveillance in 1989, and fraud relating to Contel in 1990.
[citation needed] In senior status, a case that spanned from 2002 to 2003 reduced restrictions in police surveillance, which he had imposed himself in 1985 under the Handschu guidelines, even when there is no evidence of criminal offence ([1]).
