The first session of the District Court on criminal case 40/61 was held on April 11, 1961, at Jerusalem's "Bet Ha'am." The trial terminated on December 15, 1961 with the reading of the verdict, whereby Eichmann found guilty on most of the articles of the indictment, was sentenced to death. The commencement of the trial was preceded by long months of punctilious preparation. The Israeli police set up a special unit, "Bureau 06," for the purpose of assembling the relevant documents; selecting witnesses and preparing them for their testimony; setting out the prosecution line; and discussing various legal issues. 1,600 documents were selected, most of them bearing Eichmann's signature. Likewise, a list of 108 survivor witnesses was prepared, as well as another of expert witnesses - historians and other scholars.
