Indiana Code Title 36. Local Government § 36-7-7-2

Sec. 2. (a) The legislative bodies of all the counties in a region may, by concurrent resolutions, request the establishment of a regional planning commission (referred to as a “commission” in this chapter).  Official copies of the resolutions must be forwarded to the governor, who shall then appoint himself or herself, or a member of the governor's staff to immediately notify the other members of the commission and to act as temporary chair for the election of officers.  The commission shall, by resolution, designate a name for itself that reflects the commission's role and function and that may include the words “Regional Planning Commission”.

(b) This subsection applies to each commission established after July 1, 1978.  A county participating in a commission is not subject to the tax imposed under section 12 of this chapter, unless all the concurrent resolutions establishing the commission accept the application of the tax.
