Indiana Code Title 36. Local Government § 36-7-4-1210

Sec. 1210. (a) ADVISORY.  To implement the joinder agreement, the township executive, with the approval of the township legislative body, shall appoint additional members to the advisory plan commission.  The number of additional appointments must be such that, when added to the membership of the plan commission before joinder, the total membership of the plan commission reflects the proportion that the population of the township bears to that of the municipality or county, as the case may be.  However, this proportional representation must not cause a reduction in the number of members representing that municipality or county.

(b) ADVISORY.  Each additional member shall serve for a term of two (2) years from the date of the appointment.  Members may be reappointed to subsequent terms.  The members have all the rights and privileges of a member of the advisory plan commission, including the right to vote.
