Pub. Util. Code, § 125716

Notwithstanding any other provisions of this division or of any other law, the provisions of all ordinances, resolutions, and other proceedings in the issuance by the district of any bonds, bonds with a pledge of revenues, bonds for any and all evidences of indebtedness or liability constitute a contract between the district and the holders of the bonds, equipment trust certificates, notes, or evidences of indebtedness or liability, and the provisions thereof are enforceable against the district or any or all of its successors or assigns, by mandamus or any other appropriate suit, action, or proceeding in law or in equity in any court of competent jurisdiction.

Nothing in this division or in any other law relieves the district or the territory included within it from any bonded or other debt or liability contracted by the district. Upon dissolution of the district or upon withdrawal of territory therefrom, that territory formerly included within the district, or withdrawn therefrom, shall continue to be liable for the payment of all bonded and other indebtedness or liabilities outstanding at the time of the dissolution or withdrawal as if the district had not been so dissolved or the territory withdrawn therefrom, and it shall be the duty of the successors or assigns to provide for the payment of the bonded and other indebtedness and liabilities.

Except as may be otherwise provided in the proceedings for the authorization, issuance, and sale of any revenue bonds, bonds secured by a pledge of revenues, or bonds for improvement districts secured by a pledge of revenues, revenues of any kind or nature derived from any revenue-producing improvements, works, facilities, or property owned, operated, or controlled by the district shall be pledged, charged, assigned, and have a lien thereon for the payment of the bonds as long as they are outstanding, regardless of any change in ownership, operation, or control of the revenue-producing improvements, works, facilities, or property and it shall, in any later event or events, be the duty of the successors or assigns to continue to maintain and operate the revenue-producing improvements, works, facilities, or property as long as bonds are outstanding.
