Presiding judge George Gelaga-King concluded his final disposition by saying that the punishment of the trial chamber was "fair and reasonable" looking at the totality of the crimes and the sentence, Xinhua reported.
The final decision of the appeals chamber was unanimous.
The appeals chamber "affirms the sentence of 50 years in prison and orders that the sentence be imposed immediately", King said.
