No action shall be brought directly or indirectly attacking, questioning, or in any manner contesting the legality or validity of bonds, issued or unissued, voted by any municipality, after six months from the date upon which voters in such municipal entity met pursuant to warning and voting affirmatively to issue bonds to defray costs of communications improvements or upon vote of a question of rescission thereof, whichever occurs later. This section shall be liberally construed to effect the legislative purpose to validate and make certain the validity of bonds issued or authorized by municipalities for communications system purposes, and to bar every right to question in any manner the validity of bonds voted for such purposes, and to bar every remedy therefore, notwithstanding any defects or irregularities, jurisdictional, or otherwise, after the expiration of the six-month period. (Added 2007, No. 79, § 4, eff. June 9, 2007.)
