*418GIBSON, J.
In this proceeding under CPLR article 78, the Appellate Division properly prohibited the respondent Judges and District Attorney from proceedings with the retrial of petitioner under an indictment, holding that otherwise he would twice be placed in jeopardy, in violation of his rights under the Federal and State Constitutions (U. S. Const., 5th Amdt.; N. Y. Const., art. I, § 6). We are in complete accord with the well-considered opinion at the Appellate Division and write only to emphasize the important rule concerned.
The first trial was commenced before the court without a jury and was terminated by mistrial. On the second day of the trial, the Judge announced that overnight he had recalled that his cousin was an acquaintance of defendant's father, who had mentioned to the cousin the defendant's complaint of harassment by the police  entirely unrelated to the case at bar, so far as appears  and had subsequently  about a year before the trial  telephoned the Judge's chambers and attempted to discuss the subject with the Judge's law clerk. The clerk told him that his complaint should be made to the appropriate authority *419 through the attorney said by the father to be then representing him. The Judge did not know the defendant or his father and had never talked with either of them. Stating that his recollection of the telephone call might "in some conceivable way" affect his judgment and that "perhaps it would be improper" for him to sit, the Judge "disqualif[ied]" himself, "in the interests of justice".
Prior to this, a police witness had testified and thus, of course, jeopardy had attached (Matter of Bland v. Supreme Ct., 20 N Y 2d 552).
The mistrial was granted over the strenuous objection of defense counsel who, after expressing his confidence in the Judge's ability to try and decide the case fairly and his opinion that no cause for a mistrial existed, remarked upon the tactical advantage that he had obtained  and which the prosecution could obviate in case of a new trial  by reason of the police officer's testimony at variance with the charges; and counsel made clear his contention that a retrial would subject defendant to double jeopardy and entitle him to be discharged on that ground.
The Judge's subjective appraisal of some remote possibility of bias was completely without the ambit of the well-established rule that "manifest necessity" must be shown in justification of a mistrial in circumstances such as these (United States v. Perez, 9 Wheat. [22 U. S.] 579, 580; Matter of Nolan v. Court of Gen. Sessions, 11 N Y 2d 114, 118). So radical an action requires a "scrupulous exercise of judicial discretion", after consideration of the "vital competing interests" of the prosecution and the accused (United States v. Jorn, 400 U. S. 470, 485, 486). "Yet, in the final analysis, the judge must always temper the decision whether or not to abort the trial by considering the importance to the defendant of being able, once and for all, to conclude his confrontation with society through the verdict of a tribunal he might believe to be favorably disposed to his fate" (id., p. 486).
In the appraisal of judicial conduct it is recognized, of course, that the appearance of impropriety may sometimes be as devastating as the reality; but the mistrial procedure is not designed to afford an escape hatch from the performance of an unpleasant duty. A mistrial such as this, declared as in the public interest, *420 and against the defendant's will, must have some basis of demonstrable substance  for, as the rule has it, the necessity must be "manifest". Here, the remote possibility of unfair treatment and the clear showing of prejudice to the defendant conjoined to interdict the mistrial which the court proposed and, over objection, granted.
The order appealed from should be affirmed.
Order affirmed, without costs.
