Östersund municipality was acquitted three weeks ago in the local district court. The lawyer who represented the municipality said it could not be blamed, since there are no rules that detail exactly what safety barriers should be in place. Prosecutor Lars Magnusson, however, does not agree and says to Swedish Radio that the municipality should be held responsible for the outbreak.
"I think the rules are pretty clear. The water regulations specify what kind of threats you need to prevent and parasites are on that list", Magnusson says.
For the case to be tried in the Supreme Court the District Court must apply for a leave to appeal.
