delivered the opinion of the court.

Except as to parties, the indictments in these six cases are alike. Each contains three counts; the first and second undertake to allege a conspiracy to injure and oppress in violation of § 19, Criminal Code, and the third a conspiracy to defraud the United States, contrary to § 37. Demurrers were sustained upon the ground that rightly construed neither section applies to the specified acts.

Section 37, originally part of the Act of March 2, 1867, c. 169, 14 Stat. 471, provides: “If two-or more persons conspire either to commit any offense against the United States, or to defraud the United States in any manner or for any purpose, and one or more of such parties do any act tp effect the object of the conspiracy, each of the parties to such conspiracy shall be’ fined not more than ten thou-' sand dollars, or imprisoned not more than two years, or[*224] . both.” It was considered in United States v. Gradwell, 243 U. S. 476, and held not applicable in circumstances similar to those here presented. The Government has accordingly-abandoned the third count.

Section. 19 provides: “If two or more persons conspire to injure, oppress, threaten, or intimidate any citizen in the free exercise or enjoyment of any right or privilege secured to him by the Constitution or laws of the United States, or because of his having so exercised the same, or if two or more persons go in disguise on the highway, or on the premises of another, with intent to prevent or hinder his free exercise or enjoyment of any right or privilege so secured, they shall be fined not more than five thousand dollars . and imprisoned not more than ten years, and shall, moreover, be thereafter ineligible to any office, or place of honor, profit, or trust created by the Constitution or laws of the United States.” And the two counts based thereon charge defendants with cofispiring to injure candidates for presidential electors, the United States Senate and representative in Congress at the regular election in Ohio, November 7, 1916, also qualified electors who might properly vote thereat, in the free ex-r ercise and enjoyment of certain rights and privileges secured by Constitution and laws of the . United States, namely — The right (a) of being a candidate (b) that only those duly qualifiect'should vote (c) that the results should be. determined by voters who. had not been bribed and (d) that the- election board should make a true and accurate count of votes legally cast by qualified electors and no others. The indictment further alleged the conspiracy was carried into effect as intended by-purchasing votes of certain electors and- causing election boards to receive them and make inaccurate returns.

. . The real point, involved is whether § 19 denounces as criminala^eonspiracy to bribe voters at a general election within.a State where presidential electors, a United States[*225] senator and a representative in Congress are to be chosen. Our concern is not with the power of Congress but with the proper interpretation of action taken by it. This must be ascertairied in view of the settled rule that “there can be no constructive offenses, and before a man can be punished his case must be plainly and unmistakably within the statute” (United States v. Lacher, 134 U. S. 624, 628); and the policy of . Congress to leave the conduct of elections at which its members are chosen to state law alone, except where it may have expressed a clear purpose to establish some further or definite regulation.

Departing from the course long observed, by Act of May 31, 1870, 16 Stat. 140, Congress undertook to prescribe a comprehensive system intended to secure freedom and integrity of elections. Section 19 of. that act declares “that if at any election for representative or delegate in the Congress of the United States any person shall knowingly by force, threat, menace, intimidation, bribery, reward, or offer, or promise thereof, or otherwise unlawfully prevent any qualified voter of any State of the United States of America, or of any Territory thereof, from freely exercising the right of suffrage; or compel or induce by any such means, or otherwise, any officer of an election in any such State or Territory to receive a vote from a person not legally qualified or entitled to vote; . . or aid, counsel, procure, or advise any such voter, person, or officer to do any act hereby made a crime, . . . every such person shall be deemed guilty of a crime, and shall for such crime be liable to prosecution in any court of the United States of competent jurisdiction, and, on conviction thereof, shall be punished by a fine not exceeding five hundred dollars, or by .imprisonment for a term not exceeding three years, or both, in the discretion of the' court, and shall pay the costs of prosecution.” In pursuance of a well understood policy, the Act of February 8, 1894, c. 25, 28 Stat.[*226] 36, repealed the foregoing and other kindred sections in Act of 1870 but left in effect § 6, then § 5508, Rev. Stats., and now § 19, Criminal Code. See United States v. Mosley, 238 U. S. 383; United States v. Gradwell, supra.

The Government in effect maintains that lawful voters at an election for presidential electors, senator and member of Congress and also the candidates for those places have secured to them by Constitution or , laws of the United States the right and privilege that it shall.be fairly and honestly conducted; and that Congress intended by § 6, Act of 1870, to punish interference with such right and privilege through conspiracy to influence voters by bribery.

Section 19, Criminal Code, of course, now has the same meaning as when first enacted as § 6, Act of 1870 (see Criminal Code, §§ 339, 341); and considering the policy of Congress not to interfere with elections within a State except by clear and specific, provisions, together with the rule respecting construction of criminal statutes, we cannot think it was intended to apply to conspiracies to bribe voters'. Bribery, expressly denounced in another section of the original act, is not clearly within the words used; and the reasoning relied on to extend them thereto would apply in respect of almost any act reprehensible in itself, or forbidden by state statutes', and supposed injuriously to affect freedom, honesty, or integrity of an election. This conclusion is strengthened by express repeal of the section applicable in terms to bribery and we think is rendered entirely clear by considering the nature of the rights or privileges fairly within; intendment of original § 6.

The right or privilege to be guarded, a$ indicated both by the language employed and context, was a definite, personal one, capable of enforcement by a court, and not the political, non-judicable one common to all that the public shall be protected against harmful acts, which is[*227] here relied on. The right to vote is personal and we have held it is shielded by the section in question. Ex parte Yarbrough, 110 U. S. 651; United States v. Mosley, supra. The same is true of the right to make homestead entry, United States v. Waddell, 112 U. S. 76; also, of the right of one held by a United States marshal to protection against-lawless violence. Logan v. United States, 144 U. S. 263. While the opinion in United States v. Gradwell, supra, does not determine the precise question now presented, it proceeds upon reasoning which contravenes the theory urged by counsel for the Government.

The court below properly construed the statute and its judgments are

Affirmed.
