Arnold Rebane appealed in Geneva against the decision of the eligibility officer. Five months later, the review board checked whether he was actually the responsibility of the IRO. Rebane’s appeal was rejected because he was a German citizen. In this case, the members of the review board made their decision on the basis of the case files that had been submitted. In other situations – such as that of Marinko Moadic – the applicants were also interviewed in depth. The original decision letters are stored in their own collection ( in the Arolsen Archives. By the end of 1951, the review board had made a total of 37,000 decisions.
