The defendant at the times herein mentioned was a member of the municipal police force of the city of New York. His conviction of the crime of perjury is predicated upon false testimony given by him in the prosecution of a woman named Icie Sands. The prosecution was for vagrancy under the provisions of section 887, subdivision 4, clause (a), of the Code of Criminal Procedure. The specific charge was that she had offered to commit an act of prostitution. Her trial and conviction took place in the Ninth District Magistrate’s Court, city of New York, on April 10, 1929.
The testimony given by the defendant upon the trial of Icie Sands (hereinafter referred to as Sands) was to the effect that she committed the act charged on April 5, 1929, in premises 34 West One Hundred and Thirty-fifth street, New York city; that he and his fellow officer, Baccaglini, at about three p. m. on the day in *435question, saw an unknown white man enter Sands’ apartment on the ground floor rear of said premises; that at the time they were seated in an automobile on the opposite side of the street directly in front of the hallway entrance; that after waiting about five minutes, they entered the apartment and found the Sands woman in a bedroom with an unknown white man who gave the name of Joseph Brill. Without detailing in full the defendant’s testimony, suffice it to say that it was ample to show a full and complete violation of the statute upon which Sands’ prosecution was based. She was convicted and sentenced to imprisonment for thirty days.
In support of the indictment the People’s evidence showed that no offer of prostitution had been committed by Sands; that one Chile Acuna, a witness called by the People against the defendant upon his trial, theretofore employed as a “ stool pigeon ” by the members of the vice squad of the department of police, and by the defendant himself, as a member of such squad, was the unknown man employed by the defendant in the Sands’ arrest; that by prearrangement with the defendant and Baecaglini, Acuna had preceded them to the premises; that when the defendant and Baecaglini came in shortly after Acuna’s arrival in the apartment, Acuna was in a bedroom with Sands; that the latter was fully clothed, seated on a bed and that Acuna was standing engaged in conversation with her; that when the defendant and Baecaglini arrived, Acuna informed them that they had come too soon, as he had not had sufficient opportunity to induce Sands to commit, or offer to commit, an act of prostitution; that thereupon the witness was instructed by the defendant to return to the station house, which he did; that soon thereafter the defendant and Baecaglini brought Sands to the station house under arrest.
Acuna’s testimony was supported by that of Sands and by a man named Pridgen who lived with her. Both gave testimony to the effect that it was Acuna who came to the apartment shortly prior to the arrest. The testimony of both of these witnesses differs in its detail. Sands denied that she was in the bedroom with Acuna when the officers arrived and asserted that she was engaged in conversation with him in the hallway. Pridgen’s testimony, while differing to some extent from that of the witness Sands, tended on the whole fully to support the claim of Acuna and Sands that the latter did not expose her person to Acuna.
The defendant in his own behalf testified substantially as he did on the prosecution of Sands in the Magistrates’ Court. His version of the occurrence in the apartment of Sands on the day of the arrest was substantially corroborated in detail by his fellow-officer, Baecaglini.
*436The principal issue for the jury’s determination was whether Acuna was the unknown white man who figured in the arrest of Sands. If they were warranted in giving credence to the testimony of Acuna, Sands and Pridgen, then they were fully warranted in finding the defendant guilty.
The defendant and his fellow-officer, Baccaglini, strenuously denied that Acuna was the unknown white man on the occasion in question. Both testified that they had never used Acuna as the unknown white man in making any arrest. The defendant claimed that he had met Acuna for the first time on an occasion when he made an arrest in what was referred to as the Bonilla case in February, 1929; that on such occasion Acuna was found among other unknown men in the house where the arrest was made, and that Acuna at that time volunteered to supply him with information with respect to houses of prostitution and gambling resorts; that thereafter he did receive information from time to time from Acuna who would telephone him and meet him by appointment at some designated place upon the street; that at no time had Acuna ever been at the precinct station house to which the defendant was assigned.
Acuna’s testimony was to the effect that he had been introduced to the defendant through police channels early in January, 1929, and that he had acted as the unknown man in arrests that the defendant made on several occasions between January and May, 1929. He asserted that he was the unknown man in the Bonilla case already mentioned.
In support of this claim of Acuna strong supporting evidence came from the mouth of the defendant himself. He admitted that the unknown man in that case gave the name of Charles Acuna and that he recorded such name in his records. The jury were fully justified in refusing to accept defendant’s explanation of this unusual coincidence. It was to the effect that Acuna was introduced to him on that occasion under the name of Chile and that he did not learn the witness’ full and- true name until it was disclosed in the newspapers during the investigation of the Magistrates’ Courts conducted by the referee designated by the Appellate Division. How the unknown man in the case happened to have the name of Acuna he was unable to explain.
There was other evidence which tended to support Acuna. He testified that he customarily received from five to ten dollars on each occasion when he acted as a “ stool pigeon ” for the defendant. On the occasion when Sands was arrested he testified that he was paid five dollars by the defendant. In defendant’s expense account in connection with the Sands arrest a three-dollar charge for *437information and two dollars and fifty cents for meals was concededly entered and made. The defendant’s explanation of this charge, notwithstanding that he claims to have made the arrest unaided, was that he paid one dollar to some unknown man to • whom he had spoken about the premises, and two dollars and fifty cents to the superintendent or janitor of the house where Sands lived. When the janitor was produced upon the trial the defendant was obliged to admit that he had paid no money to him.
Additional support of Acuna’s claim that he was well known to the defendant prior to the Bonilla arrest, is found in another piece of evidence. He testified that on January 30, 1929, in order to give the impression that he was notoa “ stool pigeon,” he testified for the defense in a case in the Magistrates’ Court known as the Loubet case; that the defendant was the complaining witness in that case and was in court when Acuna testified for the defense. It appears without dispute that the defendant was such complaining witness and while he denied that Acuna had testified in that case, there was evidence introduced by the People tending to support Acuna’s claim that he had so testified.
No doubt this corroborating evidence to which reference has just been made had its effect with the jury. If Acuna had in fact been used by the defendant as the unknown man in other cases, his denial thereof and his attempt to show the least possible relation with Acuna was a fact from which the jury had a right to infer a “ guilty conscience.” If Acuna had been used in other cases, but in fact had not been used in the Sands’ case, there is no reason why the defendant should not have frankly and honestly admitted his true relation with the witness.
In this view of the evidence we are clearly of the opinion that it may not be said that the finding of the defendant guilty was against the weight of the evidence. True it is that the testimony against him comes largely from tainted sources. The assistant district attorney who argued this appeal, as did the assistant who pre sented it to the jury, frankly conceded that the witnesses Acuna, Sands and Pridgen were disreputable characters. Acuna, in addition to being a confessed “ stool pigeon,” was twice convicted, once of petit larceny and again of extortion. The witness Sands was a common prostitute who, prior to her arrest and conviction on April 10, 1929, had been arrested by the defendant and convicted and sentenced to imprisonment upon his testimony. Pridgen is no doubt properly described as a “ procurer ” for the Sands woman.
Granting all this, however, their credibility was a question peculiarly for the triers of the facts who, having had the opportunity of hearing them testify, and observing their conduct and *438their manner upon the witness stand, were the best judges of the truth of their testimony. (People v. Gaimari, 176 N. Y. 84, 94; People v. Sanducci, 195 id. 361, 367; People v. Seidenshner, 210 id. 341, 359; People v. Minsky, 227 id. 94, 98; People v. Becker, 210 id. 274; People v. Cohen, 223 id. 406.)
In People v. Minsky (supra, at p. 98) it was said: “ Men have been convicted of murder in the first degree by the evidence of admittedly dangerous and degenerate witnesses, law-breakers and professional criminals.”
In People v. Cohen (supra, at p. 422) it was said: “We must accept conditions as they exist. Criminals may tell the truth. If after weighing their story, in view of all the circumstances and all corroboration, it seems credible, we need not reject it merely because their reputation is bad or their habits vicious. Such facts are but a warning that caution should be used. For it is also to be remembered that in fixing the blame for such a crime as we are here considering the State is not likely to discover witnesses of high character.”
Nor do inconsistencies or disagreements in detail of the testimony of witnesses necessarily condemn the verdict. As said in People v. Lytton (257 N. Y. 310, at p. 313): “ Inconsistencies and uncertainties are not lacking altogether. They are not so vital as to condemn the verdict. A question of fact remains, involving an appraisal by a jury of the credibility of witnesses, and incapable of satisfactory solution by the study of the printed page. (People v. Rodawald, 177 N. Y. 408, 419, 420; People v. Taylor, 138 N. Y. 398; People v. Egnor, 175 N. Y. 419, 425). ' There can be no reversal of the judgment without breaking down the barriers that separate the functions of a jury from those of an appellate court.’ ”
It is urged upon us that no adequate motive on the part of the defendant to testify falsely against the Sands woman has been shown, whereas there is ample motive on the part of Acuna, Sands and Pridgen to testify falsely against the defendant. But this, like other important facts, was peculiarly for the jury. It is to be borne in mind that where a defendant’s guilt is clearly and satisfactorily established, proof of motive in itself is not essential. (People v. Seppi, 221 N. Y. 62, 70.)
Upon examination of the numerous alleged errors which are urged upon us as sufficient to require a reversal, we find but two that require consideration. It is urged that it was error for the court to permit the witnesses Sands and Acuna to testify to the effect that they were in fact not guilty of crimes of which they had admittedly been convicted. As to his two convictions the witness Acuna was asked respecting them by the assistant district attorney *439upon direct examination, and the witness’ explanation and assertion of innocence were brought out before he was taken over on cross-examination by defendant’s counsel. The explanation offered by the witness Sands of her previous arrest and conviction where the defendant was the complaining witness, was brought out on redirect after the fact of conviction had been first elicited on her cross-examination.
Objection to the witness Acuna being permitted to testify to and explain his convictions on direct examination was made by defendant’s counsel. His objection was overruled, and the examination was permitted in the exercise of discretion of the learned trial judge. In the circumstances disclosed we are of opinion that there was no abuse of discretion in this respect. The question was one that related merely to the order of proof, as the defendant’s counsel would have been entitled to go fully into the subject upon the cross-examination of the witness.
So far as the right of the witness to explain the facts and circumstances surrounding his conviction, there can be little question. The right of a witness, or a party, when testifying to thus explain a conviction, has been sustained by the Court of Appeals (Sims v. Sims, 75 N. Y. 466). That case seems to go to the extent of holding that such a witness may in a proper case assert his innocence even in the face of a judgment of conviction. In People v. Michaels (168 App. Div. 258), however, the right of a witness in this respect was limited to an explanation of the facts and circumstances surrounding the conviction. He was not permitted to protest his innocence once his conviction was admitted.
The limitation thus placed upon a witness in the Michaels case has been applied in other jurisdictions, particularly Massachusetts. In Lamoureux v. N. Y., N. H. & H. R. R. Co. (169 Mass. 338) the plaintiff put in proof of the conviction of one of the defendant’s witnesses to discredit him. Upon redirect the witness was asked to state the circumstances of the conviction for the purpose of showing the extent the witness was involved in the act and to show the circumstances. The evidence was excluded. Mr. Justice Holmes, writing for the court, stated (p. 340): “ Logically, there is no doubt that the evidence tending to diminish the wickedness of the act, like evidence of good character, which is admissible, does meet, as far as it goes, the evidence afforded by the conviction, since that discredits only by tending to show either general bad character, or bad character of a kind more or less likely to be associated with untruthfulness. Gertz v. Fitchburg Railroad, 137 Mass. 77, 78. Nevertheless, the conviction must be left unexplained. Obviously the guilt of the witness cannot be retried. *440Commonwealth v. Gallagher, 126 Mass. 54; Gertz v. Fitchburg, 137 Mass. 77, 80. It is no less impossible to go behind the sentence to determine the degree of guilt. Apart from any technical objection, it is impracticable to introduce what may be a long investigation of a wholly collateral matter into a case to which it is foreign, and it is not to be expected or allowed that the party producing the record should also put in testimony to meet the explanation ready in the mouth of the convicted person. Yet if one side goes into the matter, the other must be allowed to also. We have considered the question as if the offer had been in the most guarded form. As it was made, it was almost identical with the one excluded in Commonwealth v. Galligan, 155 Mass. 54, 56.” (Italics ours.)
Under the rule in the Lamoureux Case (supra) defendant’s counsel was no doubt within his rights tn requesting that he be permitted to call the complainant in one of the cases where Acuna had been convicted for the purpose of controverting Acuna’s claim of innocence. However, we are of opinion that whatever error was thus committed in the court’s refusal of the request made, was fully cured. During the trial and in the court’s main charge the jury were instructed that, notwithstanding the explanations and protestations of the witnesses Acuna and Sands, the judgment of their convictions was binding and conclusive upon the issue of their guilt. In referring to their testimony in the main charge the court stated: “ The Court allowed an explanation by these witnesses as to the circumstances under which they were arrested and their protestations of innocence. I charge you that the conviction is a valid and binding judgment and remains as an adjudication of the facts.
“ In determining what weight and what value you will attach to such witnesses’ testimony, you may give their explanations and protestations such weight as you may deem proper. In any event, however, you must bear in mind that Such explanations and protestations of innocence cannot overcome or destroy the validity of the judgment of conviction. As a finding of guilt that judgment must remain unaffected and unimpaired and absolutely binding and effective as an adjudication of guilt.”
The other alleged error relates to what is termed misconduct on the part of the assistant district attorney who prosecuted the indictment against the defendant, which misconduct, it is asserted, amounted to depriving the defendant of a fair trial.
It appears that, after the People rested, the assistant prosecutor, accompanied by a photographer and a police officer from the district attorney’s office, went to the premises 34 West One Hundred and Thirty-fifth street for the purpose of taking measurements *441with a view to showing that the defendant and his fellow-officer, Baccaglini, did not have a clear view of the entrance to the Sands’ apartment at the time the defendant claimed that he saw an unknown man enter it. On the following morning the request of the prosecutor to reopen the case for the purpose of offering this proof was granted. No objection to such procedure on the part of the defendant’s counsel was taken.
It appears that the police officer who accompanied the prosecutor to the premises in question was called to testify to observations made. When it developed in the course of his examination that he admitted “ poor eyesight ” the prosecutor himself voluntarily took the Stand to testify to what he had observed. No objection whatever was raised by defendant’s counsel, and no complaint, during the summation or at any time, was made that an unfair advantage had been taken of the defendant by the assistant district attorney having testified.
It is now urged for the' first time upon appeal that this alleged misconduct on the part of the prosecutor was so prejudicial in its nature that a new trial should be granted upon this ground alone.
We are not prepared to condemn in so severe a measure the conduct of the prosecutor. At most it was but a mere error of judgment on his part, and in our view no prejudice to the defendant resulted. It is true that ordinarily an attorney representing one side or the other should refrain from taking the stand in support of his case, and even avoid placing himself in a position where his testimony will be required. (Fontana v. Fontana, 182 App. Div. 717.) However, as we view the situation here presented, the action of the assistant district attorney was neither deliberate nor preconceived. He was confronted with a sudden emergency where material testimony which he had expected to produce through another witness suddenly failed in its efficacy. Because of an unforeseen circumstance, either the evidence had to be supplied by the prosecutor himself or a further adjournment taken to have additional observations made.
In the circumstances our conclusion is that the matter is not of such serious consequence as to require either condemnation of the assistant district attorney or a reversal of the judgment. The defendant was represented on the trial by able counsel long experienced in the trial of criminal cases. Lack of protest or objection on his part to the testimony in question is strong evidence, indeed, that the incident was considered of little moment on the trial. In fact in his summation to the jury, defendant’s counsel stated: “ We have no cause to complain, Gentlemen of the Jury, about the trial of this case. This case is a beautiful illustration *442of what is meant by a fair and impartial trial under the Constitution of the United States and under the laws of the State of New York. I have no cause for complaint in the conduct of my friend here, Mr. Wallace [Assistant District Attorney].”
The testimony in question was material and entirely competent. A sufficient foundation for its introduction was laid. The evidence showed that there had been no change whatever in the physical construction of the premises. The only variance in conditions between April 5, 1929, and the time when observations were made on behalf of the prosecutor, related to visibility merely. The jury well understood that they were required to take note of these slight changes in conditions.
So far as the motion for a new trial is concerned, we have examined the evidence offered in support thereof, and in opposition thereto, and we have reached the conclusion that the learned trial judge committed no error in denying the motion made.
It follows that the judgment and order appealed from should be affirmed.
