California Public Utilities Code
The district may bring an action to determine the validity of any of its bonds, equipment trust certificates, warrants, notes, or other evidences of indebtedness pursuant to Chapter 9 (commencing with Section 860), Title 10, Part 2 of the Code of Civil Procedure.
All bonds and other evidences of indebtedness issued by the district under the provisions of this part, and the interest thereon, are free and exempt from all taxation within the State of California, except for transfer, franchise, inheritance, and estate tax.
Notwithstanding any other provisions of this part or 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 improvement districts, revenue bonds, equipment trust certificates, notes, or any and all evidences of indebtedness or liability shall constitute a contract between the district and the holders of such bonds, equipment trust certificates, notes, or evidences of indebtedness or liability, and the provisions thereof shall be 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 contained in this part or in any other law shall be held to relieve 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of the district or upon withdrawal of territory therefrom, the property formerly included within the district, or withdrawn therefrom, shall continue to be liable for the payment of all bonded and other indebtedness or liabilities outstanding at the time of such dissolution or withdrawal the same as if the district had not been so dissolved or the territory withdrawn therefrom, and it shall be the duty of the successors or assigns to provide for the payment of such bonded and other indebtedness and liabilities.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 such bonds as long as the same are outstanding, regardless of any change in ownership, operation, or control of such revenue-producing improvements, works, facilities, or property and it shall, in such later event or events, be the duty of the successors or assigns to continue to maintain and operate such revenue-producing improvements, works, facilities, or property as long as bonds are outstanding.
