Earlier FIFA President Blatter, 86, was accused of unlawfully arranging a payment from the world governing body of football to ex-UEFA chief Platini, 67, worth £1.73 million.
The two, once one of the most powerful figures in global football, had denied the charges against them.
The case meant Blatter ended his reign as FIFA president in disgrace and was partly responsible for ending Platini’s hopes of succeeding him after being banned from football when the affair came to light.
Blatter had said the payment of two million Swiss francs followed a “gentlemen’s agreement” between the pair when he asked Platini to be his technical adviser in 1998.
Platini worked as a consultant between 1998 and 2002 with an annual salary of CHF 300,000 – the most FIFA could afford due to money problems the organization was experiencing at the time, Blatter told the court.
The rest of Platini’s annual salary of one million Swiss francs would be settled at a later date, Blatter said.
The motives for the payment were unclear, although the two men met in 2010 and discussed the upcoming 2011 FIFA presidential election.
When Blatter approved the payment, he campaigned for re-election against Mohamed bin Hammam of Qatar. Platini, then UEFA president, was seen as holding sway over European members who could influence the vote.
The payment came after a major investigation launched in 2015 by the US Department of Justice into bribery, fraud and money laundering at FIFA, which led to Blatter’s resignation.

Platini, who also lost his job as UEFA president after the ban, said the affair was a deliberate attempt to thwart his bid to become FIFA president in 2015.
Platini’s former UEFA general secretary Gianni Infantino competed in the FIFA race and won the 2016 election.
