§ 329. Designation of temporary stenographer in special cases. If, pursuant to law, the attorney general or a deputy attorney general, attend before the grand jury in any county, the attorney general may appoint a temporary stenographer to take the testimony given before the grand jury in respect of matters or investigations before the grand jury conducted by the attorney general or such deputy attorney general, and may fix his compensation. Every such appointee before he enters upon the duties of his office shall take and subscribe the constitutional oath of office, and shall make oath before the county clerk of such county that he will keep secret all matters and things occurring before such grand jury. Such stenographer shall take and transcribe the testimony given before the grand jury in respect of the matter or investigation conducted by the attorney general or deputy attorney general, and shall furnish to him a full copy of all such testimony as he shall require. Except as provided in section three hundred twenty-five, such stenographer shall not permit any other person to take a copy of the same or any portion thereof, nor to read the same or any portion thereof except upon the written order of the court duly made after hearing the attorney general or deputy attorney general.
