Indiana Code Title 3. Elections § 3-6-5-15

Sec. 15. (a) Except as provided in subsection (b), this section applies when an election is conducted in a political subdivision (as defined in IC 36-1-2-13 and other than a county) that contains territory in more than one (1) county.

(b) This section does not apply to an election:

(c) To the extent authorized by this section, the county election board of the county that contains the greatest percentage of population of the political subdivision shall conduct all elections for the political subdivision.  The county election board may designate polling places for the election, which may be located in any county in which the political subdivision is located, and shall appoint precinct election officers to conduct the election upon nomination by the county chairman of the county where the precinct is located, or by filling a vacancy if a nomination is not timely made.  However, each county election board shall provide poll lists for voters, receive and approve absentee ballot applications, issue certificates of error or other documents for the voters of that county, print ballots for the municipal or special election, and conduct activity required to canvass the votes under IC 3-12-5-2(b).
