California Public Contract Code
No officer or employee in the state civil service or other appointed state official shall engage in any employment, activity, or enterprise from which the officer or employee receives compensation or in which the officer or employee has a financial interest and which is sponsored or funded, or sponsored and funded, by any state agency or department through or by a state contract unless the employment, activity, or enterprise is required as a condition of the officer's or employee's regular state employment. No officer or employee in the state civil service shall contract on his or her own individual behalf as an independent contractor with any state agency to provide services or goods.
(a) No retired, dismissed, separated, or formerly employed person of any state agency or department employed under the state civil service or otherwise appointed to serve in state government may enter into a contract in which he or she engaged in any of the negotiations, transactions, planning, arrangements, or any part of the decisionmaking process relevant to the contract while employed in any capacity by any state agency or department. The prohibition of this subdivision shall apply to a person only during the two-year period beginning on the date the person left state employment.
(b) For a period of 12 months following the date of his or her retirement, dismissal, or separation from state service, no person employed under state civil service or otherwise appointed to serve in state government may enter into a contract with any state agency, if he or she was employed by that state agency in a policymaking position in the same general subject area as the proposed contract within the 12-month period prior to his or her retirement, dismissal, or separation. The prohibition of this subdivision shall not apply to a contract requiring the person's services as an expert witness in a civil case or to a contract for the continuation of an attorney's services on a matter with which he or she was involved prior to leaving state service.
Each contractor who enters into a state contract with the state for ten thousand dollars ($10,000) or more, shall be assigned an identification number by the department. Each contractor who has been assigned a number, shall list it on each contract he or she enters into with the state, regardless of the amount of the contract.
In the case of a corporation or firm, the president's assigned number shall be used exclusively on each contract. The assigned number shall remain unchanged regardless of future name changes.
