For a period of sixty days from the date of the adoption of any resolution of the commission authorizing the issuance of its bonds or notes, any person interested may test the legality of such resolution and the validity of such bonds or notes issued or proposed to be issued thereunder, after which time no one shall have any cause of action to contest the regularity, formality, or legality of said resolution or to draw in question the legality of said bonds or notes or the debts represented thereby for any cause whatever, and it shall be conclusively presumed that every legal requirement has been complied with, and no court shall have authority to inquire into such matters after the lapse of said sixty days.
Any bonds issued in accordance with the provisions hereof shall be sold to the highest bidder, at a public sale, for not less than par and accrued interest, after advertisement, once a week for not less than thirty days, by the commission in a newspaper of general circulation published in Coushatta, Louisiana; Chicago, Illinois; New York, New York, and such other places as the commission shall determine, reserving to the commission the right to reject any and all bids, and the right to readvertise for new bids. If, after advertisement as hereinabove provided, no bids are received, or if such bids as are received are considered in the discretion of the commission to be unsatisfactory, then and in that event, the commission may publicly negotiate for the sale of such bonds.
