UNITED STATES
v.
SMULL.
No. 598.
Supreme Court of United States.
Argued January 7, 1915.
Decided February 23, 1915.
ERROR TO THE DISTRICT COURT OF THE UNITED STATES FOR THE DISTRICT OF OREGON.
*406 Mr. Assistant Attorney General Knaebel, with whom Mr. S.W. Williams was on the brief, for the United States.
No appearance or brief filed for defendant in error.
*408 MR. JUSTICE HUGHES delivered the opinion of the court.
This is an indictment for perjury. It is charged that Luther Jerome Smull, the defendant in error, in making application for a homestead entry under § 2289 of the Revised Statutes swore falsely, before the receiver of the land office, that he had not theretofore `made any entry under the homestead laws,' whereas in fact, as he well knew, he had previously made a homestead entry upon which he had obtained patent. The defendant demurred upon the ground that the indictment did not state a crime. The District Court sustained the demurrer, ruling that the affidavit was not within the statute defining perjury. Criminal Code, § 125. The Government brings the case here under the Criminal Appeals Act.
The charge of crime must have clear legislative basis. Williamson v. United States, 207 U.S. 425; United States v. Grimaud, 220 U.S. 506; United States v. George, 228 U.S. 14; United States v. Birdsall, 233 U.S. 223. The Criminal Code, § 125, provides: "Whoever, having taken an oath before a competent tribunal, officer, or person, in any case in which a law of the United States authorizes an oath to be administered, .. . shall wilfully and contrary to such oath state or subscribe any material matter which he does not believe to be true, is guilty of perjury. . . ." This statute takes the place of the similar provision of § 5392 of the Revised Statutes, which in turn was a substitute for a number of statutes in regard to perjury and was phrased so as to embrace all cases of false swearing whether in a court of justice or before administrative officers acting within their powers (see revisers' report, Vol. 2, pp. 2582, 2583).[1] It cannot be *409 doubted that a charge of perjury may be based upon § 125 of the Criminal Code where the affidavit is required either expressly by an act of Congress or by an authorized regulation of the General Land Office, and is known by the affiant to be false in a material statement. That is, the Land Department has authority to make regulations which are not inconsistent with law and are appropriate to the performance of its duties (Revised Statutes, §§ 161, 441, 453, 2478), and when by a valid regulation the Department requires that an affidavit shall be made before an officer otherwise competent, that officer is authorized to administer the oath within the meaning of § 125. The false swearing is made a crime, not by the Department, but by Congress; the statute, not the Department, fixes the penalty. United States v. Grimaud, 220 U.S., p. 522. Section 125 of the Criminal Code must be read in the light of § 2246 of the Revised Statutes which is explicit:
"The register or receiver is authorized, and it shall *410 be their duty, to administer any oath required by law or the instructions of the General Land-Office, in connection with the entry or purchase of any tract of the public lands."
As it is apparent that the departmental rule makes it necessary for the applicant to state under oath whether or not he has made a former entry under the homestead laws, the sole question in the present case is whether this requirement was one which the Department could impose. This inquiry is naturally divided into two branches: (1) Was the regulation addressed to the enforcement of the laws, the administration of which was confided to the Department, and (2) Was it inconsistent with any specific provision of the statutes?
As to the former, it is sufficient to say that the homestead laws contain an express prohibition with respect to the amount of land which any one person may secure under their provisions, and the Commissioner of the General Land Office is entrusted with the duty of promulgating appropriate rules to make this prohibition effective. Thus, by the act of May 20, 1862, c. 75, § 6 (12 Stat. 392, 393), it was provided: `That no individual shall be permitted to acquire title to more than one quarter section under the provisions of this act; and that the Commissioner of the General Land Office is hereby required to prepare and issue such rules and regulations, consistent with this act, as shall be necessary and proper to carry its provisions into effect.' The prohibition was carried forward into the Revised Statutes (§§ 2289, 2298; act of Mar. 3, 1891, c. 561, § 5, 26 Stat. 1095, 1098) and the authority of the Department to enforce it was continued and not diminished (§ 2478). It would seem to be plain that a rule requiring an affidavit from the applicant stating whether or not he had made other entries was suitably addressed to the execution of the law. United States v. Bailey, 9 Pet. 238; Caha v. United States, 152 *411 U.S. 211; United States v. Grimaud, supra; United States v. Birdsall, supra; Leonard v. Lennox, 181 Fed. Rep. 760, 766, 767.
There remains the question whether the regulation is inconsistent with the terms of the statute; that is, as there is no suggestion of inconsistency otherwise, whether it is repugnant to the specific requirements of § 2290 of the Revised Statutes as amended by the act of March 3, 1891, c. 561, supra, in relation to the affidavit to be made by the applicant for a homestead entry. We do not think that it is. Section 2290, it is true, does not provide that the affidavit of the applicant shall set forth whether there has been a previous entry. Neither does it provide that the applicant shall state that he is a citizen or has filed his declaration of intention to become such. Yet, under § 2289, he cannot make entry unless this qualification exists. We are concerned with positive requirements of the law, which are to be enforced by the Department. They are not superadded by an unauthorized departmental caution. And this being true, the fact that § 2290 is specific as to certain matters which the applicant's affidavit must contain cannot be regarded as destroying the authority of the Department to exact proof as to other facts which are also essential conditions of the right of entry and as to the existence of which the Department must be satisfied.
It is not a case where the statute points out the character of the proof to be required as to the particular fact and thus impliedly denies authority to exact proof of a different sort. Thus, with respect to final proof of residence and cultivation, § 2291 of the Revised Statutes requires the proof to be made by `two credible witnesses'  not by the claimant; accordingly it was held that Congress had provided the `exact measure' of the claimant's obligation and that the Department could neither add to nor detract from it. United States v. George, 228 U.S. 14. But *412 here the statute is silent as to the mode of proving the particular fact. Still it is an essential fact; Congress made it the duty of the Department to enforce the condition prescribed, and in the absence either of inhibition or of a requirement of some other procedure we are unable to find any ground for saying that Congress debarred the Department from availing itself of the natural and appropriate course in examining the applicant. It has been the long established departmental practice to insist upon a verified statement by him whether or not he has made an earlier entry, and we are of the opinion that the practice is authorized. The oath in such cases is administered by authority of law as provided in § 125 of the Criminal Code.
The judgment of the District Court is reversed and the case is remanded for further proceedings in conformity with this opinion.
It is so ordered.
MR. JUSTICE McREYNOLDS took no part in the consideration and decision of this case.
