Gov. Code, § 5652

No public body shall enter into any contract which provides that such public body shall be furnished any report relating to the financial feasibility of any public project or of the issuance or sale of any public securities if: (1) such contract is entered into with any person engaged in the business of rating public securities and distributing information concerning such rating to the public, unless such contract provides that no rating will thereafter be given or assigned for a period of two years by such person on any security issued, or to be issued, by said public body or any entity to which it is a party; (2) payment for any services provided for in such contract is contingent upon a finding in such report that the public undertaking or the issuance or sale of any public securities is financially feasible; or (3) the contract fails to provide that it is for personal services and nonassignable. Nothing in this section shall prohibit any public body from entering into a contract solely for a rating.
