Cal. PCC § 10296

(a) Every contract entered into by any state agency for any purpose specified in subdivisions (a) to (d), inclusive, of Section 10295, or in Section 10295.6, shall contain a statement by which the contractor swears under penalty of perjury that no more than one final, unappealable finding of contempt of court by a federal court has been issued against the contractor within the immediately preceding two-year period because of the contractor’s failure to comply with an order of a federal court which orders the contractor to comply with an order of the National Labor Relations Board. For purposes of this section, a finding of contempt does not include any finding that has been vacated, dismissed, or otherwise removed by the court because the contractor has complied with the order which was the basis for the finding. The state may rescind any contract in which the contractor falsely swears to the truth of the statement required by this section.

(b) (1) This section does not apply to a credit card purchase of goods of two thousand five hundred dollars ($2,500) or less.

(2) The total amount of exemption authorized herein shall not exceed seven thousand five hundred dollars ($7,500) per year for each company from which a state agency is purchasing goods by credit card. It shall be the responsibility of each state agency to monitor the use of this exemption and adhere to these restrictions on these purchases.
