Charles Evans Hughes, United States v. Smull — Opinion of the Court
“ 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, Comp. Stat. 1913, §§ 235, 681, 699, 5120) , 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. ”
