GOV §927.3: (a) Except where payment is made directly by a state agency pursuant to Section 927.

(a) Except where payment is made directly by a state agency pursuant to Section 927.6, an undisputed invoice received by a state agency shall be submitted to the Controller for payment by the required payment approval date. A state agency may dispute an invoice submitted by a claimant for reasonable cause if the state agency notifies the claimant within 15 working days from receipt of the invoice, or delivery of property or services, whichever is later. No state employee shall dispute an invoice, on the basis of minor or technical defects, in order to circumvent or avoid the general intent or any of the specific provisions of this chapter. (b) Except where payment is made directly by a state agency pursuant to Section 927.13, a notice of refund or other payment due received by a state agency shall be submitted to the Controller within 30 calendar days of the agency’s receipt of the notice. A state agency may dispute a refund request for reasonable cause if the state agency notifies the claimant within 15 working days after the state agency receives notice from the individual that the refund is due.
