The UN's International Criminal Tribunal for the former Yugoslavia (ICTY) cleared Serbian nationalist leader Vojislav Seselj of war crimes on Thursday.
The court judges said there was insufficient evidence to prove Seselj's responsibility for war crimes against Croats and Muslims during the country's conflicts in the early 1990s.
None of the counts of his indictment showed Seselj's guilt, according to the ICTY.
The acquittal makes Seselj a free man, presiding judge Jean-Claude Antonetti said.
The prosecution had asked for a 28-year custodial sentence.
The 61-year-old head of the nationalist Serbian Radical Party (SRS) had refused to attend the reading of the verdict.
In 2014 he was temporarily released from prison due to illness.
Seselj had voluntarily surrendered to the court in 2003.
