New York Consolidated Laws, Uniform District Court Act - UDC § 2403. Districts and number of judges therein

The county district court system shall be divided into judicial districts as follows:  The entire district court system shall constitute the first judicial district in which one district court judge shall be elected.  Each town electing to become part of the district court system, including the three or more towns establishing the system, shall constitute another judicial district, provided, however, that any two or more contiguous towns electing to become part of the district court system which have a combined total population of less than sixty thousand according to the last census, shall constitute one judicial district, but provided further, that if any of such towns shall thereafter attain a population greater than thirty thousand, such town shall constitute another judicial district.  In each judicial district there shall be elected one district court judge.  The supervisors elected in the towns comprising the first judicial district may, upon the recommendation of the board of judges of the district courts, increase the number of judges in all or any one of the districts provided that such new judicial post or posts shall be filled for a full term at the next general election held not less than three months after the creation thereof.  For the purpose of electing such judges and for the purpose of determining the boundaries of such districts, any city hereafter created from the territory of any town shall be considered to be part of that town.
