The ruling was announced by Judge Marcelo Bretas from the 7th Criminal Court in Rio de Janeiro.
The 79-year-old executive, who was the head of the Brazilian Olympic Committee for more than two decades, was found guilty of money laundering, tax evasion, corruption and criminal organization. Nuzman's lawyers appealed the sentence and he will stay free until the appeal is heard.
Nuzman, a former honorary IOC member, was first arrested in October 2017 along with his right-hand man, former Rio 2016 director of operations Leonardo Gryner, accused of arranging more than $2 million in bribes to get the IOC to pick Rio de Janeiro as host of the 2016 Olympics. Rio was awarded the Games in 2009, beating out Chicago, Tokyo and Madrid.
Gryner, former Rio de Janeiro Governor Sergio Cabral and businessman Arthur C+sar de Menezes Soares Filho were also convicted for collaborating to bribe IOC officials. Gryner was sentenced to 13 years and 10 months in jail for corruption and criminal organization.
Cabral, who has been in jail since 2016 for a series of corruption scandals, was sentenced to a further 10 years and eight months. He had given the judge details of the bribery conspiracy after reaching an agreement to disclose sensitive information on other cases.
Cabral told Bretas that he, Nuzman, Soares and Gryner coordinated "to buy the votes" of the former president of the International Association of Athletics Federations, Lamine Diack, and his son, Papa Diack, and others.
