[290 U.S. 371, 372] Messrs. John W. Carter, Jr., of Danville, Va., and Charles A. Hammer, of Harrisonburg, Va., for petitioner.
The Attorney General and Mr. Angus D. MacLean, Asst. Sol. Gen., of Washington, D.C., for the United States. [290 U.S. 371, 373]
Mr. Justice SUTHERLAND delivered the opinion of the Court.
The sole inquiry to be made in this case is whether in a federal court the wife of the defendant on trial for a criminal offense is a competent witness in his behalf. Her competency to testify against him is not involved.
The petitioner was twice tried and convicted in a federal District Court upon an indictment for conspiracy to violate the prohibition law. His conviction on the first trial was reversed by the Circuit Court of Appeals upon a ground not material here. 46 F.(2d) 417. Upon the second trial, as upon the first, defendant called his wife to testify in his behalf. At both trials she was excluded upon the ground of incompetency. The Circuit Court of Appeals sustained this ruling upon the first appeal, and also upon the appeal which followed the second trial. 66 F.(2d) 70. We granted certiorari, limited to the question as to what law is applicable to the determination of the competency of the wife of the petitioner as a witness.
Both the petitioner and the government, in presenting the case here, put their chief reliance on prior decisions of this court. The government relies on United States v. Reid, 12 How. 361; Logan v. United States, 144 U.S. 263 , 12 S.Ct. 617; Hendrix v. United States, 219 U.S. 79 , 31 S.Ct. 193, 196; and Jin Fuey Moy [290 U.S. 371, 374] v. United States, 254 U.S. 189 , 41 S.Ct. 98. Petitioner contends that these cases, if not directly contrary to the decisions in Benson v. United States, 146 U.S. 325 , 13 S.Ct. 60, and Rosen v. United States, 245 U.S. 467 , 38 S.Ct. 148, 150, are so in principle. We shall first briefly review these cases, with the exception of the Hendrix Case and the Jin Fuey Moy Case, which we leave for consideration until a later point in this opinion.
In the Reid Case, two persons had been jointly indicted for a murder committed upon the high seas. They were tried separately, and it was held that one of them was not a competent witness in behalf of the other who was first tried. The trial was had in Virginia; and by a statute of that state passed in 1849, if applicable in a federal court, the evidence would have been competent. Section 34 of the Judiciary Act of 1789 (28 USCA 725) declares that the laws of the several states, except where the Constitution, treaties, or statutes of the United States otherwise provide, shall be regarded as rules of decision in trials at common law in the courts of the United States in cases where they apply; but the court said that this referred only to civil cases, and did not apply in the trial of criminal offenses against the United States. It was conceded that there was no act of Congress prescribing in express words the rule by which the federal courts would be governed in the admission of testimony in criminal cases. 'But,' the court said (page 363 of 12 How.), 'we think it may be found with sufficient certainty, not indeed in direct terms, but by necessary implication, in the acts of 1789 and 1790, establishing the courts of the United States, and providing for the punishment of certain offences.'
The court pointed out that the Judiciary Act regulated certain proceedings to be had prior to impaneling the jury, but contained no express provision concerning the mode of conducting the trial after the jury was sworn, and prescribed no rule in respect of the testimony to be taken. Obviously, however, it was said, some certain and [290 U.S. 371, 375] established rule upon the subject was necessary to enable the courts to administer the criminal jurisprudence of the United States, and Congress must have intended to refer them to some known and established rule 'which was supposed to be so familiar and well understood in the trial by jury that legislation upon the subject would be deemed superfluous. This is necessarily to be implied from what these acts of Congress omit, as well as from what they contain.' Page 365 of 12 How. The court concluded that this could not be the common law as it existed at the time of the emigration of the colonists or the rule which then prevailed in England, and (therefore) the only known rule which could be supposed to have been in the mind of Congress was that which was in force in the respective states when the federal courts were established by the Judiciary Act of 1789. Applying this rule, it was decided that the witness was incompetent.
In the Logan Case it was held that the competency of a witness to testify in a federal court sitting in one state was not affected by his conviction and sentence for felony in another state; and that the competency of another witness was not affected by his conviction of felony in a Texas state court, where the witness had since been pardoned. The indictment was for an offense committed in Texas and there tried. The decision was based, not upon any statute of the United States, but upon the ground that the subject 'is governed by the common law, which, as has been seen, was the law of Texas ... at the time of the admission of Texas into the Union as a state.' Page 303 of 144 U.S., 12 S.Ct. 617, 630.
We next consider the two cases upon which petitioner relies. In the Benson Case two persons were jointly indicted for murder. On motion of the government there was a severance, and Benson was first tried. His codefendant was called as a witness on behalf of the government. The Reid Case had been cited as practically de- [290 U.S. 371, 376] cisive of the question. But the court, after pointing out what it conceived to be distinguishing features in that case, said (page 335 of 146 U.S., 13 S.Ct. 60, 63): 'We do not feel ourselves, therefore, precluded by that case from examining this question in the light of general authority and sound reason.' The alleged incompetency of the codefendant was rested upon two reasons, first, that he was interested, and, second, that he was a party to the record, the basis for the exclusion at common law being fear of perjury. 'Nor,' the court said, 'were those named the only grounds of exclusion from the witness stand. Conviction of crime, want of religious belief, and other matters were held sufficient. Indeed, the theory of the common law was to admit to the witness stand only those presumably honest, appreciating the sanctity of an oath, unaffected as a party by the result, and free from any of the temptations of interest. The courts were afraid to trust the intelligence of jurors. But the last 50 years have wrought a great change in these respects, and today the tendency is to enlarge the domain of competency, and to submit to the jury for their consideration as to the credibility of the witness those matters which heretofore were ruled sufficient to justify his exclusion. This change has been wrought partially by legislation and partially by judicial construction.' Attention then is called to the fact that Congress in 1864 had enacted that no witness should be excluded from testifying in any civil action, with certain exceptions, because he was a party to or interested in the issue tried; and that in 1878 (c. 37, 20 Stat. 30 (28 USCA 632)) Congress made the defendant in any criminal case a competent witness at his own request. The opinion then continues (page 337 of 146 U.S., 13 S.Ct. 60, 64):
That case was decided December 5, 1892. Twenty-five years later this court had before it for consideration the case of Rosen v. United States, supra. Rosen had been tried and convicted in a federal District Court for conspiracy. A person jointly indicted with Rosen, who had been convicted upon his plea of guilty, was called as a witness by the government and allowed to testify over Rosen's objection. This court sustained the competency of the witness. After saying that, while the decision in the Reid Case had not been specifically overruled, its authority was seriously shaken by the decisions in both the Logan and Benson Cases, the court proceeded to dispose of the question, as it had been disposed of in the Benson Case, 'in the light of general authority and of sound reason.'
It is well to pause at this point to state a little more concisely what was held in these cases. It will be noted, in the first place, that the decision in the Reid Case was not based upon any express statutory provision. The court found from what the congressional legislation omitted to say, as well as from what it actually said, that in establishing the federal courts in 1789 some definite rule in respect of the testimony to be taken in criminal cases must have been in the mind of Congress; and the rule which the court thought was in the mind of that body was that of the common law as it existed in the thirteen original [290 U.S. 371, 379] states in 1789. The Logan Case in part rejected that view, and held that the controlling rule was that of the common law in force at the time of the admission of the state in which the particular trial was had. Taking the two cases together, it is plain enough that the ultimate doctrine announced is that, in the taking of testimony in criminal cases, the federal courts are bound by the rules of the common law as they existed at a definitely specified time in the respective states, unless Congress has otherwise provided.
With the conclusion that the controlling rule is that of the common law, the Benson Case and the Rosen Case do not conflict; but both cases reject the notion, which the two earlier ones seem to accept, that the courts, in the face of greatly changed conditions, are still chained to the ancient formulae and are powerless to declare and enforce modifications deemed to have been wrought in the common law itself by force of these changed conditions. Thus, as we have seen, the court in the Benson Case pointed to the tendency during the preceding years to enlarge the domain of competency, significantly saying that the changes had been wrought not only by legislation but also 'partially by judicial construction'; and that it was the spirit (not the letter be it observed) of this legislation which had controlled the decisions of the courts and steadily removed the merely technical barriers in respect of incompetency, until generally no one was excluded from giving testimony, except under certain peculiar conditions which are set forth. It seems difficult to escape the conclusion that the specific ground upon which the court there rested its determination as to the competency of a codefendant was that, since the defendant had been rendered competent, the competency of the codefendant followed as a natural consequence.
This view of the matter is made more positive by the decision in the Rosen Case. The question of the testi- [290 U.S. 371, 380] monial competency of a person jointly indicted with the defendant was disposed of, as the question had been in the Benson Case, 'in the light of general authority and of sound reason.' The conclusion which the court reached was based, not upon any definite act of legislation, but upon the trend of congressional opinion and of legislation (that is to say of legislation generally), and upon the great weight of judicial authority which, since the earlier decisions, had developed in support of a more modern rule. In both cases the court necessarily proceeded upon the theory that the resultant modification which these important considerations had wrought in the rules of the old common law was within the power of the courts to declare and make operative.
That the present case falls within the principles of the Benson and Rosen Cases, and especially of the latter, we think does not reasonably admit of doubt.
The rules of the common law which disqualified as witnesses persons having an interest long since in the main have been abolished both in England and in this country; and what was once regarded as a sufficient ground for excluding the testimony of such persons altogether has come to be uniformly and more sensibly regarded as affecting the credit of the witness only. Whatever was the danger that an interested witness would not speak the truth-and the danger never was as great as claimed-its effect has been minimized almost to the vanishing point by the test of cross- examination, the increased intelligence of jurors, and perhaps other circumstances. The modern rule which has removed the disqualification from persons accused of crime gradually came into force after the middle of the last century, and is to-day universally accepted. The exclusion of the husband or wife is said by this court to be based upon his or her interest in the event. Jin Fuey Moy v. United States, supra. And whether by this is meant a practical interest in the result of the prosecution [290 U.S. 371, 381] or merely a sentimental interest because of the marital relationship makes little difference. In either case, a refusal to permit the wife upon the ground of interest to testify in behalf of her husband, while permitting him, who has the greater interest, to testify for himself, presents a manifest incongruity.
Nor can the exclusion of the wife's testimony, in the face of the broad and liberal extension of the rules in respect of the competency of witnesses generally, be any longer justified, if it ever was justified, on any ground of public policy. It has been said that to admit such testimony is against public policy because it would endanger the harmony and confidence of marital relations, and, moreover, would subject the witness to the temptation to commit perjury. Modern legislation, in making either spouse competent to testify in behalf of the other in criminal cases, has definitely rejected these notions, and in the light of such legislation and of modern thought they seem to be altogether fanciful. The public policy of one generation may not, under changed conditions, be the public policy of another. Patton v. United States, 281 U.S. 276, 306 , 50 S.Ct. 253, 70 A.L.R. 263.
The fundamental basis upon which all rules of evidence must rest-if they are to rest upon reason-is their adaptation to the successful development of the truth. And, since experience is of all teachers the most dependable, and since experience also is a continuous process, it follows that a rule of evidence at one time thought necessary to the ascertainment of truth should yield to the experience of a succeeding generation whenever that experience has clearly demonstrated the fallacy or unwisdom of the old rule.
It may be said that the court should continue to enforce the old rule, however contrary to modern experience and thought, and however opposed, in principle, to the general current of legislation and of judicial opinion it may [290 U.S. 371, 382] have become, leaving to Congress the responsibility of changing it. Of course, Congress has that power; but, if Congress fail to act, as it has failed in respect of the matter now under review, and the court be called upon to decide the question, is it not the duty of the court, if it possess the power, to decide it in accordance with present-day standards of wisdom and justice rather than in accordance with some outworn and antiquated rule of the past? That this court has the power to do so is necessarily implicit in the opinions delivered in deciding the Benson and Rosen Cases. And that implication, we think, rests upon substantial ground. The rule of the common law which denies the competency of one spouse to testify in behalf of the other in a criminal prosecution has not been modified by congressional legislation; nor has Congress directed the federal courts to follow state law upon that subject, as it has in respect of some other subjects. That this court and the other federal courts, in this situation and by right of their own powers, may decline to enforce the ancient rule of the common law under conditions as they now exist, we think is not fairly open to doubt.
In Hurtado v. California, 110 U.S. 516, 530 , 4 S.Ct. 111, 118, 28 L. Ed.232, this court, after suggesting that it was better not to go too far back into antiquity for the best securities of our liberties, said:
Compare Holden v. Hardy, 169 U.S. 366 , 385-387, 18 S.Ct. 383.
To concede this capacity for growth and change in the common law by drawing 'its inspiration from every fountain of justice,' and at the same time to say that the courts of this country are forever bound to perpetuate such of its rules as, by every reasonable test, are found to be neither wise nor just, because we have once adopted them as suited to our situation and institutions at a particular time, is to deny to the common law in the place of its adoption a 'flexibility and capacity for growth and adaptation' which was 'the peculiar boast and excellence' of the system in the place of its origin.
The final question to which we are thus brought is not that of the power of the federal courts to amend or repeal any given rule or principle of the common law, for they neither have nor claim that power, but it is the question of the power of these courts, in the complete absence of congressional legislation on the subject, to declare and effectuate, upon common-law principles, what is the present rule upon a given subject in the light of fundamentally altered conditions, without regard to what has previously been declared and practiced. It has been said so often as to have become axiomatic that the common law is not immutable but flexible, and by its own principles adapts itself to varying conditions. In Ketelsen v. Stilz, 184 Ind. 702, 111 N.E. 423, L.R.A. 1918D, 303, Ann. Cas. 1918A, 965, the Supreme Court of that state, after pointing out that the common law of England was based upon usages, customs, and institutions of the English [290 U.S. 371, 384] people as declared from time to time by the courts, said (page 707, of 184 Ind., 111 N.E. 423, 425):
That court then refers to the settled doctrine that an adoption of the common law in general terms does not require, without regard to local circumstances, an unqualified application of all its rules; that the rules, as declared by the English courts at one period or another, have been controlling in this country only so far as they were suited to and in harmony with the genius, spirit, and objects of American institutions: and that the rules of the common law considered proper in the eighteenth century are not necessarily so considered in the twentieth. 'Since courts have had an existence in America,' that court said (page 708 of 184 Ind., 111 N.E. 423, 425), 'they have never hesitated to take upon themselves the responsibility of saying what are the proper rules of the common law.'
And the Virginia Supreme Court of Appeals, in Hanriot v. Sherwood, 82 Va. 1, 15, after pointing to the fact that [290 U.S. 371, 385] the common law of England is the law of that commonwealth except so far as it has been altered by statute, or so far as its principles are inapplicable to the state of the country, and that the rules of the common law had undergone modification in the courts of England, notes with obvious approval that 'the rules of evidence have been in the courts of this country undergoing such modification and changes, according to the circumstances of the country and the manner and genius of the people.'
The Supreme Court of Connecticut, in Beardsley v. City of Hartford, 50 Conn. 529, 542, 47 Am.Rep. 677, after quoting the maxim of the common law, cessante ratione legis, cessat ipsa lex, said:
The same thought is expressed in People v. Randolph, 2 Parker, Cr. R. ( N.Y.) 174, 177:
It was in virtue of this maxim of the common law that the Supreme Court of Nevada, in Reno Smelting Works v. Stevenson, 20 Nev. 269, 21 P. 317, 4 L.R.A. 60, 19 Am.St.Rep. 364, in a well-reasoned opinion, held that the common-law doctrine of riparian rights was unsuited to conditions prevailing in the arid land states and territories of the West, and therefore was without force in Nevada; and that, in respect of the use of water, the applicable rule was based upon the doctrine of prior appropriation for a beneficial use. [290 U.S. 371, 386] In Illinois it was held at an early day that the rule of the common law which required an owner of cattle to keep them upon his own land was not in force in that state, notwithstanding its adoption of the common law of England, being unsuited to conditions there in view of the extensive areas of land which had been left open and unfenced and devoted to grazing purposes. Seeley v. Peters, 5 Gilman (Ill.) 130.
Numerous additional state decisions to the same effect might be cited; but it seems unnecessary to pursue the matter at greater length.
It results from the foregoing that the decision of the court below, in holding the wife incompetent, is erroneous. But that decision was based primarily upon Hendrix v. United States and Jin Fuey Moy v. United States, supra, and in fairness to the lower court it should be said that its decision was fully supported by those cases.
In the Hendrix Case the opinion does not discuss the point; it simply recites the assignment of error to the effect that the wife of Hendrix had not been allowed to testify in his behalf, and dismisses the matter by the laconic statement, 'The ruling was not error.' In the Jin Fuey Moy Case it was conceded at the bar that the wife was not a competent witness for all purposes, but it was contended that her testimony was admissible in that instance because she was offered, not in behalf of her husband, that is, not to prove his innocence, but simply to contradict the testimony of government witnesses who had testified to certain matters as having transpired in her presence. The court held the distinction to be without substance, as clearly it was, and thereupon disposed of the question by saying that the rule which excludes a wife from testifying for her husband is based upon her interest in the event, and applies without regard to the kind of testimony she might give. The point does not seem to have been considered by the lower court to which the writ of error was addressed ((D. C.) 253 F. 213); nor, as plainly appears, was the real point as it is here involved presented [290 U.S. 371, 387] in this court. The matter was disposed of as one 'hardly requiring mention.' Evidently the point most in the mind of the court was the distinction relied upon, and not the basic rule which was not contested. Both the Hendrix and Jin Fuey Moy Cases are out of harmony with the Rosen and Benson Cases and with the views which we have here expressed. In respect of the question here under review, both are now overruled.
Mr. Justice CARDOZO concurs in the result.
Mr. Justice McREYNOLDS and Mr. Justice BUTLER are of opinion that the judgment of the court below is right and should be affirmed.
