Article on the Prosecution's appeal of Sefer Halilovic's acquital.
There was another case, I believe it was a case involving members of the KLA who were accused of crimes against Serb civilians where the prosecution in their appeal of the verdict also said that the judges exceeded the normal "beyond a resonable doubt" and were looking for "beyond a shadow of a doubt."
So, on the one hand you have the trial chambers in the cases believing that the Prosecution did not prove their case beyond a resonable doubt.
On the otherhand, the OTP says that the judges are applying a standard for more strict than the "beyond a resonable doubt" standard.
Completely shallow side note: I've seen a picture of Halilovic's son, Semir, and he's quite good looking!
