Indiana Code Title 15. Agriculture and Animals § 15-12-1-17

Sec. 17. (a) The business and affairs of an association shall be managed by a board of directors of at least five (5) directors. Subject to this limitation, unless specifically provided in the articles of incorporation, the number of directors shall be fixed by the bylaws, except as to the number constituting the initial board of directors. The number constituting the initial board of directors shall be fixed by the articles of incorporation.

(b) The number of directors may be increased or decreased from time to time by amendment of the bylaws, but a decrease in the number of directors may not shorten the term of an incumbent director. In the absence of articles of incorporation or bylaws that fix the number of directors, the number of directors must be the same as stated in the articles of incorporation for the initial board of directors.
