Stephen Yagman (born December 19, 1944) is an American former federal civil rights lawyer and advocate. He had a reputation as an effective counsel and advocate, particularly in cases regarding allegations of police brutality, and as a "pugnacious civil rights lawyer."
On November 22, 2010, Yagman was disbarred, based upon federal convictions on June 22, 2007, for tax evasion, bankruptcy fraud, and money laundering. In the tax case, he "was found guilty of trying to avoid paying more than $100,000 in federal income taxes while living what prosecutors painted as a lavish lifestyle that included Aspen vacations, high-end suits from London, and fine dining."
Yagman contended that the IRS had selectively and vindictively prosecuted him, ignoring the difference between tax avoidance, which is legal, and tax evasion, which is not, because, as Idaho Special Prosecutor (1997–2001), he prosecuted homicide charges against FBI sniper Lon Horiuchi for allegedly murdering Vicki Weaver at Ruby Ridge, Idaho in 1992 and because on January 19, 2002 he brought the first Guantanamo Bay detainee case and won it on December 18, 2003.
Yagman's federal convictions were affirmed on appeal by the United States Court of Appeals for the Ninth Circuit.
Stephen Yagman was born in 1944 in Brooklyn, New York to working-class parents. His father was a dental technician and his mother was a secretary. Yagman attended Abraham Lincoln High School. After attending the State University of New York at Buffalo, he then graduated from Long Island University in Brooklyn.
