O'BRIEN, J.

The defendant was convicted in the Court of Sessions of Fulton county of the crime of robbery in the first degree, charged to have been committed upon the person of one Plank by entering his house in the night time, binding him and taking certain money which it is claimed he had in his possession. Plank was the principal, if not the only witness at the trial who testified in regard to the facts and circumstances constituting the offense and who attempted to identify the defendant as one of the persons present on the occasion and actively participating in the robbery. He testified that there were four other persons present with him, but did not attempt to identify them by any direct or positive testimony. His version of the transaction tending to establish the commission of a crime and to identify the defendant as one of the persons engaged in it, is not free from contradictions, and contains some elements of improbability.

While the credibility of his testimony was entirely for the jury, its salient features can properly be kept in view when considering the competency and probable effect with the jury of certain confessions of guilt claimed to have been made by the defendant, and which were given in evidence against him, as well as evidence offered in his behalf tending to explain or entirely destroy these alleged confessions.

The defendant, at the time of his arrest, was found in a saloon at night and taken to the lock-up in a state of intoxication, from which he had not recovered, when, about two o'clock in the morning, he was aroused from sleep by a justice of the peace, who presented to him a paper just prepared by the justice and the district attorney, which was read to the defendant, signed by his mark and sworn to before the justice. The paper was given in evidence at the trial by the prosecution, and in it the defendant states, in the technical language of an indictment, that he and four other persons named therein committed the robbery. The testimony of Plank was in this way corroborated, not only as to the commission of a crime, but as to the identity of the defendant as one of its perpetrators, in concert with the four other persons named in the confession. The defendant offered to prove by three of the four persons named in the paper, and by other witnesses, that on the night when the robbery was alleged to have taken place, they were not and could not have been at Plank's house or in the vicinity, but were, in fact, at another place. Like proof was offered to show that the fourth person named in the paper as the defendant's accomplice could not possibly have been present or participating in the commission of the offense. This testimony was objected to by the district attorney on the ground that, though it might prove that the four persons named in the paper as defendant's accomplices, who were not on trial, did not participate in the crime, yet it could not affect the admission of the defendant that he was himself an actor in the transaction. The court sustained the objection and the defendant excepted.

The case made by the people was that five persons were engaged in the commission of the offense, one of whom was identified as the defendant. In view of the testimony given by Plank, and the whole theory of the prosecution to assume that the robbery was committed by the defendant alone, or in concert with persons other than those named in the paper, would destroy all effect to which it might otherwise be entitled as a confession of guilt. If it could be established to the satisfaction of the jury that the defendant's statement, as evidenced by the paper, in regard to the presence and guilty connection of these four persons with the commission of the offense was false, that would tend to destroy the credit to which it might otherwise be entitled. While it was entirely possible that the defendant may have committed the crime in concert with four other persons not named in the paper, yet he had the right to prove, if he could, that important parts, at least, of the confession were not entitled to any credit with the jury, especially as he was indicted jointly with three of the persons described in the confession as his confederates. The peculiar circumstances under which the defendant's signature was obtained to the paper tended greatly to impair its value as evidence against him, and had he been permitted to submit to the jury the proof which he offered to produce, they might very well have rejected the entire confession as unreliable. The testimony tended to impeach the force and effect of written admissions of guilt obtained from the defendant when he was in a condition in which he would not be likely to understand it, and under circumstances that tended to deprive it of the character of a voluntary statement, and was, therefore, admissible.

When the paper above referred to was offered in evidence the defendant's counsel offered, before it was received, to show that it was obtained from the defendant under a promise of immunity from punishment for robbery, or some other crime for which he then stood charged. The court decided, notwithstanding this offer to receive the paper in evidence, and rejected the proof offered by the defendant until the case was with the defense, stating that it would then be stricken out if proved to have been procured under the circumstances embraced in the offer. The defendant's counsel excepted to this ruling. The competency of the writing as evidence against the defendant was a question of law which he had a right to ask the court to decide before the evidence was admitted. It frequently happens that the testimony is of such a character as to require the court to submit the question to the jury, to be rejected by them altogether or given such weight as under all the circumstances the jury may deem proper to give to the alleged confession. But when, as in this case, a written confession of guilt is offered against a person on trial for a criminal offense, and he objects to the same and offers to prove to the court that it was procured from him by threats, or promises, or under such circumstances as would render it incompetent as evidence, it is error to receive the paper without first hearing the proof offered and deciding upon the competency of the confession as evidence against the party making it. ( Commonwealth v. Culver, 126 Mass. 464.)

When the paper in question was read to the jury, under the sanction of the court, without first hearing what the defendant had to allege against its competency, he was to that extent denied a fair trial, though the paper was received conditionally with the understanding that it should be stricken out of the case if it afterwards was shown to be incompetent.

There were some other rulings at the trial contained in the record, of which the defendant complains, that would be difficult to sustain, but as they may be changed upon another trial it is unnecessary to notice them here. The proceedings at the trial have been referred to sufficiently to show that the conviction was properly reversed by the court below.

The judgment should be affirmed.
