Dismissal of corruption charges paves way for ANC leader to become SA president in 2009.
The hearings at the high court in Pietermaritzburg concluded on Tuesday.
More than 1,000 of Zuma’s supporters demonstrated outside the court, denouncing charges they believe are politically motivated.
Zuma has long been under a cloud because of a 1999 arms deal, but a chief prosecutor decided not to press charges in 2003.
President Thabo Mbeki fired Zuma as the country’s deputy president in 2005 after Zuma’s financial adviser was sentenced to 15 years in jail for trying to elicit bribes from a French company.
New charges were filed against him in 2005, but these were thrown out in 2006 on a technicality.
