The Niebergall affidavit is in substance the same as the Coogan affidavit which was accepted by the International Military Tribunal as sufficient authentication of documents used in Case No. 1. However, in addition to these affidavits, the prosecution in this case will attach to each document submitted in evidence, other than self-proving documents such as affidavits signed by the defendants, a certificate signed by an employee of the Evidence Division of the Office of Chief of Counsel for War Crimes, reading, for example, as follows: “I, Donald Spencer, of the Evidence Division of the Office of Chief of Counsel for War Crimes, hereby certify that the attached document, consisting of one photostated page and entitled, ‘Letter from John Doe to Richard Rod, dated 19 June 1943,’ is the original of a document which was delivered to me in my above capacity, in the usual course of official business, as a true copy of a document found in German archives, records, and files captured by military forces under the command of the Supreme Commander, Allied Expeditionary Forces. “To the best of my knowledge, information, and belief, the original document is at the Berlin Document Center.” So much for the authentication of documents to be presented in this trial. I turn now briefly to the distribution of documents which we will use. The prosecution made available to the Defendants’ Information Center approximately a week ago three photostatic copies of the great bulk of the documents which will be used in our case-in-chief. These documents are of course in German. In addition, the prosecution has prepared document books in both German and English which contain, for the most part, mimeographed copies of the documents, arranged substantially in the order in which they will be presented in this court. Each document book contains an index giving the document number, description, and page number. A space is also provided for writing in the index number. Twelve official copies of the German document books will be filed in the Defendants’ Information Center at least 24 hours prior to the time that particular material will be introduced in court. In addition, defense counsel will receive seven so-called unofficial German document books, which will contain mimeographed copies prepared primarily for the German Press. Six official copies of the German document books will be presented to the Tribunal—one for each of the Justices on the bench and one for the Secretary General. Two of such document books will contain photostatic copies in order that the Tribunal may from time to time refer to the original. Document books will also be made available to the German interpreters and court reporters.
