Whenever a court requiring grand and petit juries or petit juries is established for and held in a territorial subdivision of the county, the jury commission shall make and keep a separate roll and make a separate box for that court and territorial subdivision, on which roll and in which box only the names of jurors residing in that territory shall be placed, which box shall be kept by the clerk of said court and the key thereof by the judge of said court, and all jurors for that court shall be drawn by the judge of said court as provided in this article from the separate jury box provided under this section and shall be summoned as provided by law for summoning jurors otherwise drawn. The names of jurors whose names are required to be placed on the roll and in the box provided for in this section shall not be placed on any other roll nor in any other box nor shall any such person be authorized or required to serve as a juror in any court outside of said territorial subdivision.

If there is more than one court requiring grand and petit juries or petit juries established for and held in such territorial subdivision of the county, all of such courts shall procure their juries from the box provided for in this section.

This section is intended to apply to any division of a court that is held in such territorial subdivision, including the probate court. It is not the object or effect of this section to repeal or affect any local law.
