Brazil's Federal Supreme Court acquitted former President Fernando Collor de Mello of corruption charges.
The court Thursday said prosecutors failed to prove Collorwas directly involved in diverting public funds through public contracts.
He was the head of state from 1990 to 1992.
"There is no proof or concrete evidence against the suspect, only unproven elements gathered during the investigations," the court ruled.
Collor was accused with a group of businessmen of embezzling public funds and laundering money in bank accounts set up using fake names or nominees.
The case was called the "mensalao," or monthly payout.
The first mesalao trials opened in 2012.
The allegedly embezzled money, prosecutors said, was used to buy votes in the congress.
"National Deputy Attorney General Ela Wiecko said Collor, a member of the Brazilian Labor Party, knew about the scheme, which led to the recent conviction and sentencing of several party leaders," the Global Times said.
Collor resigned the presidency in September 1992 to avoid impeachment.
