v.
NOVECK.
No. 169.
Supreme Court of United States.
Argued January 25, 1926.
Decided May 10, 1926.
ERROR TO THE UNITED STATES DISTRICT COURT FOR THE SOUTHERN DISTRICT OF NEW YORK.
Assistant to the Attorney General Donovan, with whom Solicitor General Mitchell was on the brief, for the United States.
*202 Mr. Ben A. Matthews for defendant in error.
MR. JUSTICE BUTLER delivered the opinion of the Court.
Defendant in error was indicted November 5, 1923. The first count alleges the commission of perjury on March 13, 1920,  more than three years before indictment. The District Court quashed that count on the ground that the prosecution was barred by the statute of limitations. The case is here under the Criminal Appeals Act of 1907, c. 2564, 34 Stat. 1246.
The count charges "the crime of perjury as defined by section 125 of the United States Criminal Code." That section 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, that he will testify, declare, depose, or certify truly, or that any written testimony, declaration, deposition, or certificate by him subscribed, is true, shall willfully and contrary to such oath state or subscribe any material matter which he does not believe to be true, is guilty of perjury, . . ." 35 Stat. 1088, 1111. The substance of the charge is that defendant in error on oath stated that the income tax due from S. Noveck & Co., Inc., for 1919, was $1,484.84 on an income of $16,251.66, whereas in fact the tax due was $45,664.91 on an income of $124,127.13. And it is alleged that the perjury was committed "for the purpose of defrauding the United States."
Section 1044 of the Revised Statutes, as amended by the Act of November 17, 1921, c. 124, 42 Stat. 220, provides: "No person shall be prosecuted, . . . for any offense, not capital, except as provided in section 1046, unless the indictment is found . . . within three years next after such offense shall have been committed: Provided, however, That in offenses involving the defrauding or attempts to defraud the United States . . . the period *203 of limitation shall be six years." The amendatory Act added the proviso. Section 1046, Revised Statutes, declares that no person shall be prosecuted for any crime arising under the revenue laws unless the indictment is found within five years after the committing of such crime. The Act of July 5, 1884, c. 225, 23 Stat. 122, as amended by the Revenue Act of 1921, c. 136, 42 Stat. 227, 315, fixes a three-year period of limitation for offenses arising under the internal revenue laws of the United States. Section 125 of the Criminal Code, under which the indictment was found, is not a part of and does not refer to the revenue laws. The limitations fixed in respect of offenses arising under those laws do not apply. See United States v. Hirsch, 100 U.S. 33; United States v. Rabinowich, 238 U.S. 78.
Plaintiff in error contends that, as the perjury in this case is charged to have been committed in the making of an income tax return, and is specially alleged to have been committed for the purpose of defrauding the United States, the offense is brought within the proviso to § 1044, and that the six year period of limitation applies. But the alleged purpose to defraud the United States is not an element of the crime defined in § 125, on which the indictment is based. That allegation does not affect the charge; it need not be proved and may be rejected as mere surplusage. In re Lane, 135 U.S. 443, 448. The construction of §§ 125 and 1044 contended for by the Government divides perjury into two classes. It makes one include offenses having the elements specified in § 125 and the other to include those containing the further element of purpose to defraud the United States. And that would apply similarly to every offense to which the three year period fixed by § 1044 was applicable before the proviso was added. The effect is to create offenses separate and distinct from those defined by specific enactments. Obviously that was not intended. The Act of *204 November 17, 1921, merely added a proviso to a statute of limitations. Statutes will not be read to create crimes, or new degrees or classes of crime, unless the purpose so to do is plain. The language in question does not require the construction contended for. Indeed it is not at all appropriate for the making of such classifications or the creation of offenses. Its purpose is to apply the six year period to every case in which defrauding or an attempt to defraud the United States is an ingredient under the statute defining the offense. There are several such offenses. Section 37 affords an illustration. But perjury as defined by § 125 does not contain any such element.
Judgment affirmed.
