after stating the case, delivered the opinion of the court.

It is insisted that the Supreme Court of' the District of Columbia, sitting as a criminal court, had no jurisdiction; that .the questions were not authorized under the Constitution ; and that the act of Congress under which petitioner was indicted and tried is unconstitutional.

Sections 102, 103 and 104, and section 859, of the Revised Statutes, are as follows :

“ Sec. 102. Every person who, having been summoned as a witness by the authority of either House of Congress, to give testimony or to produce papers upon any matter under inquiry before either House, or any committee of either House of Congress, wilfully makes défault, or who, having appeared, refuses to answer any question pertinent to the question under inquiry, shall be deemed guilty of a misdemeanor, punishable by a fine of not more than one thousand dollars nor less than one hundred dollars, and .imprisonment in a common jail for not less than one month nor more than twelve months.

“Sec. 103. No witness is privileged to refuse to testify to any fact, or to produce any paper, respecting which he shall be examined by either House of Congress, or by any committee of either House, upon the ground that his testimony to such fact or his production of such paper may tend to disgrace him or otherwise render him infamous.

“Sec. 104. Whenever a witness summoned as mentioned in section one hundred and two fails to testify, and the facts are reported to either House, the President of the Senate of the Speaker of the House, as the case- may be, shall certify the fact under the seal of the Senate or House to the district attorney for the District of Columbia, whose duty it shall be to bring the matter before the grand jury for their action.”

[*665] “Sec. 859. No testimony given by a witness before either House, or before any committee of either House of Congress, shall be used as evidence in any criminal proceeding against him in any court, except in a prosecution for perjury committed in giving such testimony. But an official paper or record produced by him is not within the said privilege.”

These sections were derived from an act of January 24,1857, entitled “ An act more effectually to enforce the attendance of witnesses on the summons of either House .of Congress, and to compel them to discover testimony,” 11 Stat. 155,'c. 19, ^[1] as amended by an act entitled “=An act amending the provi[*666] sionsof the second section of the act of January twenty-fourth, eighteen hundred and fifty-seven, enforcing the attendance of witnesses before committees of either House of Congress,” approved January 24, 1S62, 12 Stat. 333, c. 11; ^[1] both of which are given in the margin.

From the record of the proceedings on the trial, accompanying and made part of the petition, it appears that petitionei, in declining to answer the questions propounded, expressly stated that he did not do so on the ground that to answer might expose him, or tend to expose him, to criminal prosecution ; nor did he object that his answers might tend to disgrace him. Section 103 had, in fact, no bearing on the controversy in regard to this witness, and it is difficult to see how he can properly raise the question as to its constitutionality, notwithstanding section 859. And we cannot concur in the view that sections 102 and 103 are so inseparably connected that it can be reasonably concluded that if section 103 were not sustainable, section 102 would, therefore, be invalid. In other words, we do not think that there is ground for the belief that Congress would not have enacted section 102, if it had been supposed that a particular class of witnesses, to which petitioner did not belong, if they refused to answer by reason of constitutional privilege, could not be deprived of that privilege by section 103.

[*667] Laying section 103 out of view, we are of opinion that sections 102 and 1.04 were intended, in the language of the title of the original act of January 24, 1857, “ more effectually to enforce the attendance of witnesses on the summons of either House of Congress, and to compel them to discover testimony.” To secure this- result it was provided that when a person summoned as a witness by either House to give testimony or produce papers, upon any matter under inquiry before either House, or any committee of either House, wilfully fails to appear, or, appearing, refuses to answer “ any question pertinent to the question under inquiry,” he shall be deemed guilty of a misdemeanor and punished accordingly. And it was also provided that when, under such circumstances, the facts are reported to either House, the President of the Senate or the Speaker of the House, as the case may be, shall certify the fact under the seal of the Senate or House to the district attorney for the District of Columbia, that the matter may be brought before the grand jury for their action.

It is true that the reference is to “ any ” matter under inquiry, and so on, and it is suggested that this is fatally defective because too broad and unlimited in its extent; but nothing is better settled than that statutes should receive a sensible construction, such as will effectuate the legislative intention, and, if possible, so as to avoid an unjust or an .absurd conclusion, Lau Ow Bew v. United States, 144 U. S. 47, 59; and we think that the word “ any,” as used in these sections, refers to matters within the jurisdiction of the two Houses of Congress, before them for consideration and proper for their action ; to questions pertinent thereto; and to facts or papers bearing thereon. When the facts are reported to the particular House, the question or questions may undoubtedly be withdrawn or modified, or the presiding .officer directed not to certify; but if such a contingency occurs, or if no report is made or certificate issued, that would be matter of defence, and the facts of report and certificate need not be set out in an indictment under the statute. In this case, we must assume that there was such report and certificate, and indeed we do not understand this to be controverted, as it could not well be in view[*668] of the Senate proceedings as disclosed by its journal and otherwise. Senate Journal, 53d Cong., 2d Sess. p. 238; Senate Rep. No. 477, lb.; Cong. Rec., Ib. p. 6143.

Under the Constitution the Senate of the United States has the power to try impeachments ; to judge of the elections, returns and qualifications of its own members; to determine the rules of its proceedings, punish its members- for disorderly behavior, and, with the concurrence of two thirds, expel a member; and it necessarily possesses the inherent power of self-protection.

According-to the preamble and resolutions, the integrity and purity of members of the Senate had been questioned in a manner calculated to destroy public confidence in the body, and in such respects as might subject members to censure or expulsion. The Senate, by the action taken, signifying its judgment that it was called upon to vindicate itself from aspersion and to deal with such of its members as might have been guilty of misbehavior -and brought reproach upon it, obviously had jurisdiction of the subject-matter of the inquiry it directed, and power to compel the attendance of witnesses, and to require them to answer -any question pertinent thereto. And the pursuit of such inquiry by the questions propounded in this instance was not, in our judgment, in violation of the security against unreasonable searches and seizures protected by the Fourth Amendment.

In Kilbourn v. Thompson, 103 U. S. 168, among other important rulings, it was held that there existed no general power in Congress,-or in either House, to make inquiry into the private affairs of a citizen; that neither House could, on the .allegation that an insolvent- debtor of the United States was' interested in a private business partnership, investigate the affairs of that partnership, as a mere matter of private concern; and that consequently there was no authority in either House to compel a witness to testify on the subject. The case at bar is wholly different. Specific charges publicly made against Senators had been brought to the attention of the Senate, and the Senate had determined that investigation was necessary. The subject-matter-as affecting the Senate[*669] was within the jurisdiction of the Senate. The quéstions were not intrusions into the affairs of the citizen; they did not seek to ascertain any facts as to the conduct, methods, extent or details of the business of the firm in question, but only whether that firm, confessedly engaged in buying and selling stocks, and the particular stock named, was employed by any Senator to buy or sell for him any of that stock, whose market price might be affected by the Senate’s action. We cannot regard these questions as amounting to an unreasonable search into the private affairs of the witness simply because he may have been in some degree connected with the alleged. transactions, and as investigations of this sort are within the' power of either of the two Houses they cannot be defeated on purely sentimental grounds.

The questions were undoubtedly pertinent to the subject-matter of the inquiry. The resolutions directed the committee to inquire “ whether any Senator has been, or is, speculating in what are known as sugar stocks during the consideration of the tariff bill now before the Senate.”. What the Senate might or might not do upon the facts when ascertained, we cannot say, nor are we called upon to inquire whether such ventures might be defensible, as contended in argument, but it is plain that negative answérs would have cleared that body of what the Senate regarded as offensive imputations, while affirmative answers might have led to further action on the part of the Senate within its constitutional powers.

Nor will it do to hold that the Senate had no jurisdiction to pursue the particular inquiry because the preamble and resolutions did not specify that the proceedings were taken for the purpose of censure or expulsion, if certain facts were disclosed by the investigation. The matter was .within the range of the constitutional powers of the Senate. The resolutions adequately indicated that the transactions referred to were deemed by the Senate reprehensible and deserving of condemnation and punishment. The right to expel extends to all cases where the offence is such as in the judgment- of the Senate is inconsistent with the trust and duty of a mem[*670] ber. 1 Story on Const. § 838. Reference is there made to the case of William Blount, who was expelled from the Senate in July, 1797, for “a high misdemeanor entirely inconsistent with his public trust and duty as a Senator.” The offence charged against him, said Mr. Justice Story, was an attempt to seduce an American agent among the Indians from his duty, and to alienate the affections and confidence of the Indians from the public authorities of the United States, and a negotiation for services in behalf of the British government among .the Indians. It was not a statutable offence nor was it committed in his official character, nor was it committed during the session of Congress, nor at the seat of government.

Commenting on this case, Mr. Sergeant says in his work on Constitutional Law, 2d ed. p. 302: “In the resolution, the Senate declared him guilty of a high misdemeanor, though no presentment or indictment had been found against him, and no prosecution at law was ever commenced upon the case. And, it seems no law existed, to authorize such prosecution.”

The two Houses of Congress have several times acted upon this rule of law, and the cases may be found, together with debates on the general subject, in both Houses, of great value, in Smith’s Digest of Decisions and Precedents, Senate Doc. No. 278, ;53d Cong., 2d Session. The reasons for maintaining the right inviola’te are eloquently presented in the report of the committee in the case of John Smith, accused in 1807 of participating in the imputed treason of Aaron Burr. 1 Hall’s Am. L. Journal, 159; Smith’s Digest, p. 23.

We cannot assume on this record that the action of the Senate was without a legitimate object, and so encroach upon the province of that body. Indeed, we think it affirmatively appears that the Senate was acting within its right, and it was certainly not necessary that the resolutions should declare in advance what the Senate meditated doing when the investigation was concluded.'

Doubtless certain general principles announced in Runkle v. United States, 122 U. S. 513, 555, cited by petitioner’s counsel as conclusive, were correctly set forth, but that case has not been approved in subsequent decisions on the same[*671] subject, and the presumptions in favor of -official action have been held to preclude collateral attack on the sentences of courts-martial, though courts of special and limited jurisdiction. United States v. Fletcher, 148 U. S. 84; Swaim v. United States, 165 U. S. 553.

Counsel contend with great ability that the law under consideration is necessarily subject to being impaled on one or the other of two horns of a dilemma, either inflicting a fatal wound. The one alternative is that the law delegates to the District of Columbia Criminal. Court the exclusive jurisdiction and powér to punish as contempt the acts denounced, and thus deprives the Houses of Congress of their constitutional functions in the particular class of cases. The other alternative is that if the law should be interpreted as leaving in the Houses the power to punish such acts, and vesting in addition jurisdiction in the District Criminal Court to punish the same acts as misdemeanors, then the law is invalid because subjecting recalcitrant witnesses to be twice put in jeopardy for the same offence contrary to the Fifth Amendment.

The refusal to answer-pertinent questions in a matter of inquiry within the jurisdiction of the Senate, of course, constitutes a contempt of that body, and by the statute this is also made an offence against the United States.

The history of Congressional investigations demonstrates the difficulties under which the two Houses have labored, respectively, in compelling unwilling witnesses to disclose facts deemed essential to taking definitive action, and we quite agree with Chief Justice' Alvey, delivering the opinion of the Court of Appeals, “that Congress possessed the constitutional power to enact a statute to enforce the attendance of witnesses and to compel them to make disclosure of evidence to enable the respective bodies to discharge their legitimate functions”; and that it was to effect this that the act of 1857 was passed. It was an act necessary and proper for carrying into execution the powers vested in Congress and in each House thereof. ¥e grant that Congress could not divest itself, or either of its Houses, of the[*672] essential and inherent power to punish for contempt, in cases to which the power of either House properly extended; but, because Congress, by the act of 1857, sought to aid each of the Houses in the discharge of its constitutional functions, it does not follow that any delegation of the power in each to punish for'contempt was involved; and the statute is not open to objection on that account.

Nevertheless, although 'the power to punish for contempt still remains in each House, we must decline to decide that this law is invalid because it provides that contumacy in a witness called to testify in a matter properly under consideration by either House, and deliberately refusing to answer questions pertinent thereto, shall be a misdemeanor against the United States, who are interested that the authority of neither of their departments, nor of any branch thereof, shall be defied and set at naught. It is improbable that in any case cumulative penalties would be imposed, whether by way of punishment merely, or of eliciting the answers desired, but it is quite clear that the contumacious witness is not subjected to jeopardy twice for the same offence, since the same act may be an offence against one jurisdiction and also an offence against another; and indictable statutory offences may be punished as such, while the offenders may likewise be subjected to punishment for the same acts as contempts, the two being diverso intuitu and capable of standing together. General Houston's case, Attorney General Butler, 2 Ops. Attys. Gen. 655 ; Rex v. Lord Ossulston, 2 Strange, 1107; Cross v. North Carolina, 132 U. S. 131; In re Debs, Petitioner, 158 U. S. 564; State v. Woodfin, 5 Iredell, 199; Yates v. Lansing, 9 Johns. 395; State v. Williams, 2 Speers, (Law,) 26; Foster v. Commonwealth, 8 W. & S. 77. ’

In our opinion the law is not open to constitutional objection, and the record does not exhibit a case in which, on any ground, it can be held that the Supreme Court of the District, sitting as a criminal court, had no jurisdiction to render judgment. .

Writ denied.
