Tribunal prior to the commencement of trial shall be made in writing and
filed with the General Secretary of the Tribunal at the Palace of
Justice, Nuremberg, Germany.
(b) Any such motion, application or other request shall be communicated
by the General Secretary of the Tribunal to the Chief Prosecutors and,

the determination of the question raised.

the closing or clearing of the Tribunal or take any other steps which to
the Tribunal seem just.
