A number of lawyers had offered to appear for his defense, and Eichmann chose Servatius. As a result, the Israeli law had to be changed to enable this, as until that time foreign lawyers had no right of audience in the Israeli courts. The change made enabled only those facing a capital charge to be represented by a non-Israeli lawyer. Before he was appointed to defend Eichmann, Mossad investigated the history of Servatius, but they found nothing which greatly troubled them. Although hired by Eichmann, Servatius was paid by the Israeli government, following a precedent set at Nuremberg. He was assisted in the defense of Eichmann by Dieter Wechtenbruch.

Oktober 1894 in Köln, war im Ersten Weltkrieg Artillerieoffizier gewesen und hatte am Ende des Zweiten Weltkrieges den Rang eines Majors erreicht. Da er nie der NSDAP angehort hatte oder von den Alliierten in irgendeiner Weise mit NS-Verbrechen in direkten Zusammenhang gebracht worden war, wurde er in Nuernberg als Strafverteidiger zugelassen."
