The provisions of this part and any such resolution and any such mortgage, pledge, assignment, security interest, insurance agreement, or indenture of trust shall constitute a contract with the holder or holders of the bonds and continue in effect until the principal of, the interest on, and the redemption premiums, if any, on the bonds so issued have been fully paid or provision made therefor, and the duties of the issuing city or county and its agencies and officers under this part and any such resolution and any such mortgage, pledge, assignment, security interest, insurance agreement, or indenture of trust shall be enforceable as provided therein by any bondholder by mandamus, foreclosure of any such mortgage, pledge, assignment, security interest, insurance agreement, or indenture of trust or other appropriate suit, action or proceeding in any court of competent jurisdiction; provided, the resolution or any mortgage, pledge, assignment, security interest, insurance agreement, or indenture of trust under which the bonds are issued may provide that all such remedies and rights to enforcement may be vested in a trustee (with full power of appointment) for the benefit of all the bondholders, and that the trustee shall be subject to the control of such number of holders or owners of any outstanding bonds as specified in the resolution.
