California Code, Public Utilities Code - PUC § 29143

(a) The district is hereby authorized to issue revenue bonds, payable, in whole or in part, from revenues made available under this article.  Those revenues are deemed to be revenues of the enterprise for all purposes of the Revenue Bond Law of 1941 (Chapter 6 (commencing with Section 54300) of Part 1 of Division 2 of Title 5 of the Government Code), and the restrictions therein provided against the securing of bonds by the taxing power or the proceeds of taxation do not apply.  The district is deemed a “local agency” and the planning, acquiring, constructing, operating or maintaining of the district's rapid transit facilities, or any part thereof, is deemed an “enterprise,” within the meaning of the Revenue Bond Law of 1941.  The provisions of that law not inconsistent with any of the provisions of this article are made applicable to the district, except that no election shall be required for the issuance of revenue bonds authorized by the board pursuant to this article and secured, in whole or in part, by the revenues made available under this article.  Notwithstanding any provision of the Revenue Bond Law of 1941, the resolution or indenture authorizing the issuance of any revenue bonds secured, in whole or in part, by those revenues shall provide that the use of the revenues by the district to redeem bonds shall be continued in effect until the bonds are fully paid or provision has been made for their payment in full.

(b) Notwithstanding Section 54388 of the Government Code or any other law, the revenue bonds authorized by this article may be sold through negotiated sale conducted in accordance with Section 53591 of the Government Code.

(c) The district may borrow money in anticipation of the revenues made available under this article and may, from time to time, issue negotiable notes for that purpose.

(d) In addition to pledging revenues for the payment of any revenue bonds, the district may pledge for the payment of the bonds all other income or receipts of the district which are not required by law to be used for other purposes.
