Indiana Code Title 8. Utilities and Transportation § 8-1-11.1-24

Sec. 24. (a) All such revenue obligations shall be valid without the necessity of any approval of or ratification by either the commission or the department of local government finance. The board of directors for utilities, upon adopting a resolution authorizing such revenue obligations, shall certify a copy thereof to the city controller of such city who shall thereupon prepare said revenue obligations, and the same shall be issued in the name of the city and shall be executed by the mayor of said city and attested by the city controller and the clerk of the city-county council. Facsimile signatures may be used in executing such revenue obligations, provided that one or more of the signatures on the revenue obligations shall be manually signed, except that all signatures on interest coupons may be facsimile signatures.

(b) Certificates of indebtedness issued under section 23 of this chapter shall be executed solely by the president of the board of directors without the execution of the mayor. The signature of the president must be attested by the secretary of the board.

(c) Such revenue obligations shall be sold by the city controller of said city subject to the requirements of IC 5-1-11; provided, that any revenue obligations maturing within one (1) year of date of issuance need not be sold at public sale but may be sold in such manner as the board of directors for utilities may determine; and, provided further, that any revenue obligations may be offered for sale and sold to the United States or to any corporation owned or controlled by the United States without notice by publication. No suit to question the validity of any revenue obligations so issued or to prevent their issuance or sale shall be instituted after the date fixed for the sale of such revenue obligations and all such revenue obligations from and after such date shall be incontestable, except for fraud, forgery, or violation of constitutional provisions.
