This court has never before been asked to grant a new trial on the ground of newly discovered evidence, to impeach the character of a witness sworn on a former trial. This can not be owing to the fact that cases have not arisen in which the question could have been made, for scarcely has there been an important trial, with many witnesses, where diligent search would not have discovered evidence of this character against some witness on the trial. But it must be owing to the unbroken current of authority on the subject, early established elsewhere, that rendered it highly improbable that an attempt of this kind would be successful. Indeed the only hope the petitioner seems to entertain of his case, is based upon making it appear that it is an exception to the general rule, which he freely admits is adverse to his"claim.
The'general rule is, that a new trial will not be granted on account of newly discovered evidence to impeach the character of witnesses sworn on a former trial. Dickinson v. Blake, 6 Bro. P. C., 538; Bunn v. Hoyt, 3 Johns., 255; Shumway v. Fowler, 4 id., 425; Duryee v. Dennison, 5 id., 248; Flemming v. Hollenbach, 7 Barb., 271; Price v. Ward, 2 Halst., 127; Reed v. McGrew, 5 Ham., 375; Den v. Geiger, 4 Halst., 225.
Is this case an exception to the rule ? It is not pretended *370that it comes under any established exception ; but the claim is, that a verdict was rendered against the petitioner in the court below upon the testimony of the respondent alone, and therefore justice requires that the. court should make it an exception. How the law would be if the fact was so it is unnecessary to determine, for we are satisfied that there was other testimony, highly important, in support of the respondent’s case. It is true the respondent was the sole witness who testified directly to what took place between the parties at the time the release was given, but the conduct of the parties afterwards, in relation to the claim, was very significant of what then occurred. If one of the witnesses, Richard M. Clark, was to be believed, there was but little cause to doubt that the respondent told the truth in his testimony. This witness testified to admissions of' the debt by the petitioner, and promises to pay it, on two different occasions, and detailed all the facts and circumstances connected therewith. How could this testimony be true without the existence of the main fact. Is it to be supposed that the petitioner promised to pay a claim wiped out forever by the release ? It is possible, but not probable.
There was other evidence of importance in support of the respondent’s case. The respondent testified that in one of the interviews with the petitioner in relation to the claim the petitioner was desirous of a further postponement of payment, and promised to send him some old Madeira wine, which was soon after sent. The petitioner testified that he did not send the wine, that he did not order any to be sent or pay for any, but protested against its being sent. The protestation against its being sent, without stating who sent it, and explaining the circumstance, was evidently uttered without consideration, and shows that he knew more in relation to the subject than he was willing to reveal. The respondent represented the transaction as an inducement for him to postpone payment at that time, and, if so, it was highly important.
Some presumption might arise in favor of the respondent from the conduct of the parties after the release was given. We see the respondent pursuing the petitioner with great per *371sistency of purpose to recover Ms claim, meeting Mm again and again in relation thereto, as the petitioner admits ; and it seems from the testimony of the petitioner that he bore the importunity with patience not to have been expected of one who was under no obligation to pay, and who had informed the respondent again and again that he never would pay. All this was in keeping with the theory of the plaintiff on the trial, and hardly in accord with that of the defendant.
We see no good reason for making this case an exception to the general rule.
There is another fatal objection to the petitioner’s case. Although it is stated in his petition that he had no knowledge or means of knowledge that the character of the respondent for truth and veracity was not equal to that of mankind in general, and that the want of such knowledge or means of knowledge was attributable to no fault or want of diligence on his part, still the petition sets forth facts which go to show that he did' not exercise that degree of diligence which is required by the rule established by this court in the case of Waller v. Graves, 20 Conn., 310. It appears that 'it was well known to the petitioner that the respondent resided in the city of New Haven, and had done so many years, and that the petitioner resided in the city of New York, a place within three hours ride from New Haven; and that the declaration sets forth with great particularity the grounds of the respondent’s case. It told the petitioner that the respondent was seeking to recover the amount of the debt released, on a promise made by him at the time, and in consideration of the release. He knew that there was no one present when the release was given but himself and the respondent, and of course no one could testify to such a promise but the respondent. He had every reason to expect, therefore, that the respondent would testify to such a promise, that is, that he would commit perjury on the petitioner’s theory. He knew that general reputation from its very nature woirld be generally known. It appears too that, with all this knowledge, he had more than one year to prepare his case for trial. How then can the petitioner say that he exercised any degree of diligence to procure this evidence, when he went to trial under the expectation that the respon*372dent would commit perjury, and knowing full well, if his character for truth and veracity was bad, slight enquiry on the subject would reveal the fact ? Would not a person of ordinary caution and discernment have suspected that if a man was base enough to commit so gross a perjury his general reputation for truth might be bad ? And would'he not have made enquiry on the subject ? We think this objection is fatal to the petitioner’s cause.
On the whole we are satisfied that the petition is insufficient in the law, and so advise the superior court.
In this opinion the other judges concurred.
