“State of South Dakota, County of Hughes. H. W. Sawyer certifies that the foregoing account is just and true (or were actually paid for the necessary expense of this affiant, while in the discharge of his official duty), and that the prices therein mentioned are just and correct, and that this bill, nor any part thereof, has been paid. H. W. Sawyer.
“Subscribed and sworn to before me this 10th day of April 1897. Philip Lawrence, Notary Public, South Dakota. ”
The paper containing the foregoing statement and the following endorsement thereon, was the only voucher presented for the defendant’s approval or rejection:
“As chairman of the board of railroad commissioners, I hereby certify the within account to the auditor of the state *21of South Dakota for the issuance of his warrant upon the treasurer in accordance with the provisions of an act entitled ‘An act to provide for the establishment of a board of railroad commissioners, etc.,’ approved March 8th, 1889. W. H. Tompkins, Chairman.”
In refusing to issue warrant demanded, the defendant, upon the account rendered, made the following notation.
“Warrant for within claim is refused until receipts for money alleged to have been expended are attached, or until satisfactory evidence is furnished to show that alleged expenses were actually incurred, according to the tenor of letter from state auditor under date of Jan. 6, 1897, copies of which were served upon members of the railroad commission, and of which claimant has had due notice. H. E. Mayhew, Auditor, by E. F. Schwartz, Deputy.”
One of the rules formulated by the defendant upon assuming his official duties’ and to which particular attention is directed in his letter of January 6, 1897, is: “That where claims are presented for money expended, in addition to the itemized voucher, a receipt from the party receiving the money will be required in all cases without exception. Sheriffs, members of the state boards, and all officers presenting bills for traveling and other expenses, will be required to attach to the voucher presented to this office a receipt for any and all sums expended by them. Blank receipts will be furnished upon application.”
According to Webster’s Dictionary, and inordinary acceptation, the noun “auditor” is used to designate “a person appointed and authorized to audit or examine an account or accounts, compare the charges with the vouchers, examine the parties and witnesses, allow or reject charges, and state the balance. One who hears judicially,” etc. Sec. 69 of the Compiled Laws provides that: “All accounts and claims against the state which shall be by law directed to be paid out of the treasury thereof shall be presented to the auditor, who shall examine and adjust the sums which shall be found due from *22the state and shall issue warrants payable at the state treasury,” etc. It will thus be seen that the legislature has not only invested the auditor with power to hear and determine, but by express enactment required him to investigate and adjust, every claim for expenses against the state presented for the issuance of a warrant upon funds appropriated and payable at the state treasury. Counsel’s contention that the defendant, by rejecting the claim for the reasons stated, in effect refused to act officially, and that mandamus is, therefore, a proper remedy, is not entitled to favorable consideration. In the absence of a statute to the contrary, the auditor, in the management of his official affairs, may make and enforce rules that are reasonable and consistent with sound public policy. As a matter of fact, the number and character of demands upon the treasury for money suggests the necessity of systematic methods and regulations by which the auditor may, in the orderly performance of his trust, require, act upon, and for his own protection retain in' the official archives, the best proof of which a claim against the state is susceptible. A receipt from one to whom money has been paid, though not conclusive evidence, is a proper voucher of the fact; and a rule requiring that a receipt for items claimed as traveling and incidental expenses must accompany a demand upon the state for a warrant in payment therefor, is not, in this class of'cases, unreasonable. Plaintiff’s right to a warrant depends primarily upon the fact that expenses of a nature entitling him to reimbursement from the treasury of the state were actually sustained in the amount claimed, and the defendant had the right to take upon himself the responsibility of rejecting the claim by refusing to issue a warrant, for the reason that it was not, in his judgment, sufficiently shown “that the alleged expenses were actually incurred.” It is a matter of common knowledge that, in the absence of any law requiring it, some of the departments of the federal government insist upon the observance of a similar rule; and the legislature of this state, as a condition precedent to the is*23suance of a warrant upon funds appropriated has, by express enactment, required certain officers to submit to the state auditor together with other vouchers, receipts for all disbursements of whatever kind. Comp. Laws, § 245. Moreover, the rule is elementary, and consequently well settled, that mandamus will not issue to control the acts of, or review the methods by which, an officer has discharged a public duty, concerning, and in the performance of which, the law has clothed him with discretion to examine, adjust, allow, or reject. People v. Auditor of Colorado Territory, 2 Colo. 97; People v. Supervisors of City and County of San Francisco, 11 Cal. 43; Merrill, Mand. 110. Although, upon a refusal to act, the auditor may be required to jmoceed within the exercise of his discretion, it is only when the law has specially enjoined upon such officer a ministerial duty that mandamus will lie to compel its performance in a particular manner. Comp. Laws, § 5517. The following cases sustain the doctrine that mandamus is not a remedy by which to review or interfere with the discretionary action of an officer to whom the people have intrusted the responsibility of auditing claims against the state: People v. Auditor General, 38 Mich. 746; Danley v. Whiteley, 14 Ark. 687; State v. Doyle, 38 Wis. 92; State v. Board of Com’rs, 119 Ind. 444, 21 N. E. 1097. When, as in this case, an officer has, in the exercise of his discretion, examined and disallowed a claim, mandamus will not issue to reverse his judgment and compel him to act in a specific manner diametrically opposite. Tilden v. Board of Sup’rs, 41 Cal. 68; People v. Common Council of Troy, 78 N. Y. 33; State v. Carey, (N. D.) 49 N. W. 164; Hoole v. Kinkead, 16 Nev. 217; State v. Lafayette County Court, 41 Mo. 224.
Were it conceded that the legislature has made the issuance of a warrant by the auditor a mere ministerial duty, by conferring upon the board of railroad commissioners power to adjust, audit, and certify its secretary’s expense account, the certificate upon the back thereof would be wholly insufficient, *24for the reason that it in no manner tends to show that said board has ever taken any official action thereon to ascertain that the same is a legal charge, just and true, no part of which has been paid. That the auditor should have and exercise discretion in the examination and adjustment of claims against the state, with power to reject the same, was the clear intention of the framers of the constitution, as well as the legislative assembly; and to the law of the land and the people, who, in their sovereign capacity, placed him on guard at the threshold of the treasury, he must answer and account for his stewardship. To all persons deeming themselves aggrieved by the refusal of the state auditor to allow and issue a warrant upon a just demand against the state, the legislature has provided a plain, speedy, and adequate remedy at law, which constitutes the exclusive means for the enforcement of a rejected claim like the one before us. Laws 1890, Chap. 1., The statute viewed in the light which eminent lawyers have thrown upon jurisprudence, and the well considered cases from the foundation of our governmental system, leads us irresistibly to the conclusion that it is not the province of mandamus to settle differences of opinion between a claimant and the auditor as to the sufficiency of evidence offered in support of an unliquidate demand upon the latter for a warrant in payment of expenses not specifically provided for by law. The application for a writ of mandamus is, therefore, denied.
