Section 328 - Designation of temporary stenographers to take place of or in addition to official stenographers1. In case of the absence by reason of illness, or other cause, of the official stenographer to any grand jury in any county of this state, the district attorney of the county may designate a stenographer to perform the duties of such official stenographer during such absence, and the stenographer so designated shall receive the compensation which the official stenographer would have received for the same service, and the same shall be deducted from the salary of the official stenographer.2. Whenever it shall appear to the judge or justice presiding at a term of court for which a grand jury has been drawn that the public welfare will be promoted by a more expeditious disposition of the offenses to be inquired into by such grand jury or that the volume of business to be taken up and disposed of by it requires it, he may make an order directing the district attorney of the county in which such grand jury is sitting to appoint one or more additional grand jury stenographers to assist the official stenographer or stenographers. Upon the filing of such order in the office of the clerk of such county and the service of a copy thereof upon the district attorney of such county, the latter shall designate and appoint as many temporary stenographers as such order directs and each such appointment shall be made in the manner prescribed by section three hundred twenty-three.3. Each stenographer appointed in pursuance of the provisions of subdivision two of this section shall be subject to all the duties, penalties and provisions specified in this article as though he were appointed pursuant to the provisions of section three hundred twenty-one hereof and shall receive as compensation for his services such sum as shall be determined by the board of supervisors or county legislature of the county in which he is appointed, except that in the counties embraced within the city of New York the compensation of said stenographers shall be fixed by the board of estimate of the city of New York.4. The term of office of any temporary stenographer appointed under the provisions of subdivision two of this section shall terminate at such time as the judge or justice ordering the appointment may thereafter determine, but in no event shall it continue beyond the time of the discharge by the court of the grand jury for which the temporary appointment was made.
