Neb. Rev. Stat. §§ 77-1749
The Tax Commissioner and other proper authority or person shall in his or her final settlement with the treasurer allow him or her credit for the amount so certified, but if the Tax Commissioner or other proper authority or person shall have reason to believe that the amount stated in the certificate is not correct, or that the allowance was illegally made, he or she shall return the same for correction. When it appears to be necessary in the opinion of the Tax Commissioner or other proper authority or person, he or she shall designate and appoint some competent person to examine the treasurer's books and statement of settlement, and the person so designated and appointed shall have access to the treasurer's books and papers appertaining to such treasurer's office or settlement for the purpose of making such examination.
