Acosta was also cleared of accusations he concealed income received from the federation.
The not-guilty verdicts were handed down by a Lausanne court on Wednesday following two days of testimony last week.
The charges were brought by Mario Goijman, the former head of the Argentine Volleyball Federation. Goijman fell out with Acosta following the 2002 World Championships in Argentina over financial issues that escalated into Goijman's 2003 expulsion by FIVB from any volleyball-related posts, reports aroundtherings.com
Since then, Goijman has been seeking charges against Acosta and other FIVB leaders, including a complaint to the IOC Ethics Commission, which was dismissed in 2004 when Acosta resigned his IOC membership.
