The court sentenced one officer to 18 months prison for criminal negligence, but found two other senior policemen not guilty of the same charges.
One commander, Bambang Sidik Achmadi, had been accused of ordering his police unit to fire tear gas at match attendees. But the local court in East Java found that such charges "had not been proven".
Police commissioner Wahyu Setyo Pranoto was also acquitted.
"There is no causal relationship between the defendant's actions and the victim. The negligence element is also not proven. So the defendant should be declared not guilty," said chief judge Abu Achmad Sidqi Amsya.
Human rights groups have criticised the verdict, questioning the legal procedure. Families of the victims had been critical of the trial since it started in January behind closed doors.
Mr Irfan, head of local rights group Kontras, said it was "reasonable to suspect that the panel of judges is acting unfairly in the trial process of this case".ยูฟ่าสล็อตเว็บตรง
