Ariz. Rev. Stat. § 23-790
On request of an agency which administers an employment security law of another state or foreign government and which has found in accordance with the provisions of that law that a claimant is liable to repay benefits received under such law by reason of having knowingly made a false statement or misrepresentation of a material fact with respect to a claim taken in this state as an agent for such agency, the commission may collect the amount of such benefits from the claimant to be refunded to the agency. In any case in which under this section a claimant is liable to repay any amount to the agency of another state or foreign government, the amounts may be collected without interest by civil action in the name of the commission acting as agent for such agency, but court costs shall be paid by the liable state.
