The judgment is in line with the former decision, and is the strictest punishment ever given in a rape case in Norway.
The High Court found in April the dancer Julio Kopseng guilty of raping 16 women , one attempted rape and abuse of his former partner.
Prosecutors therefore believed that the only proper punishment for serial abuser was the strictest punishment after having listened to 100 witnesses explaining how 38-year-old brutally raped or attempted to rape women either using brute force or by having drugged them down.
He was sentenced with the same punishment given to 22 July terrorist Anders Behring Brevik.
– We are pleased that the Court of Appeal agrees with our assessment of the seriousness of the case. We believe it was the right assessment. We have never known a similar case with so extensive scale in this country and this shows that we take it seriously and that the justice system works, says Attorney Guro Hansson Bull to VG.
Julio Kopseng is known from children channel of the state TV NRK Super and Norwegian Talents.
