SPOKANE, Wash. (AP) – A man who was fired after he investigated police corruption on the Spokane Indian Reservation has won a $400,000 lawsuit against the Bureau of Indian Affairs for malicious prosecution.

Senior Federal Judge Justin Quackenbush ruled in favor of Duane Garvais, who claimed he was prosecuted by the agency at the behest of the Spokane Tribe.

Garvais was hired by the BIA in 1999 as a criminal investigator and assigned to the Spokane Reservation. In 2001, he learned that two fellow officers were stealing car stereos and other equipment. The BIA launched a criminal investigation of Garvais and he was eventually prosecuted in Spokane Tribal Court.
