Miss. Code § 49-17-759
All bonds (other than refunding bonds, interim notes and certificates of indebtedness, which may be validated) issued pursuant to this act shall be validated as now provided by law in Sections 31-13-1 through 31-13-11, Mississippi Code of 1972; however, notice of such validation proceedings shall be addressed to the citizens of the respective public agencies (a) which have contracted with the county authority pursuant to this act, and (b) whose contracts and the payments to be made by the public agencies thereunder constitute security for the bonds of such county authority proposed to be issued, and that such notice shall be published at least once in a newspaper or newspapers having a general circulation within the geographical boundaries of each of the contracting public agencies to whose citizens the notice is addressed. Such validation proceedings shall be instituted in any chancery courts within the boundaries of the county authority. The validity of the bonds so validated and of the contracts and payments to be made by the public agencies thereunder constituting security for the bonds shall be forever conclusive against the county authority and the public agencies which are parties to said contracts; and the validity of said bonds and said contracts and the payments to be made thereunder shall never be called in question in any court in this state.
