(65 ILCS 5/11-135-9) (from Ch. 24, par. 11-135-9)
    Sec. 11-135-9. Whenever a water commission has been constituted pursuant to this Division 135, was functioning as such on July 21, 1959, and thereafter continued to exercise the powers conferred on it at the time it was so constituted, such commission is a valid public corporation, and all acts performed by or on behalf of such commission, or its officers or employees are valid.
    In all cases where a municipality which has adopted a resolution or ordinance to acquire and operate jointly a waterworks system or a common source of supply of water, or both, as the case may be, under the provisions of this Division 135, thereby becoming a member of a water commission, has heretofore adopted an ordinance repealing the aforesaid resolution or ordinance and declaring the termination of membership and withdrawal of such municipality from said water commission; and the said water commission has not at the time of such ordinance acquired a waterworks system or common source of supply of water, as the case may be; and the said water commission duly adopts a resolution finding that the withdrawal of such municipality will not burden or adversely affect the remaining members of said water commission in their efforts to acquire and operate jointly a waterworks system or a common source of supply of water or both, as the case may be, and consenting to the withdrawal of such municipality, each such resolution is hereby made a legal and valid consent to the withdrawal of such municipality from the said water commission and such withdrawal is hereby declared legal and valid and effective, and such municipality is hereby declared legally and validly withdrawn from the said water commission and no longer a member or a part of the system and all such water commissions are hereby declared legally and validly organized and established water commissions, and valid and existing water commissions and public corporations under the provisions of Division 135, notwithstanding any such withdrawal.
    All actions taken prior to the effective date of this Act by any water commission which has heretofore consented to the withdrawal of one or more of its members in accordance with the procedures described herein, which actions were otherwise valid but for the invalidating effect of the membership or withdrawal from membership of the withdrawing community or communities upon any quorum, voting or other requirement based upon the number of commissioners or commission members, are hereby declared effective, legal and valid, notwithstanding any lack of compliance with any such quorum, voting or other requirement imposed by law or by the rules of the said commission.
