Defendant was permitted to plead guilty to robbery in the first degree to cover all five counts in an indictment and all other charges in the county. Fifty-three days later, defendant was' sentenced. During these proceedings he was repre*347sented by counsel of his own choosing, and in court was aided by an official Spanish interpreter, provided by the court. Fourteen months after conviction, defendant moved to vacate the judgment.

The County Court, Bronx County, denied Avithout a hearing defendant’s motion for the Avrit of error coram nobis. The Appellate Division has reversed the County Court and ordered a hearing.

The defendant contends that, if he can establish either that he was unable to consult with his counsel or that his plea was induced by the failure of the official interpreter to correctly translate the trial court’s inquiries and by the fraud of his counsel, the judgment of conviction must be vacated.

It is now well settled that ‘ ‘ Avhere the defendant alleges facts which, if established, justify relief by Avay of coram nobis, then, he ‘ is entitled to a trial thereof in open court unless his claims are ‘ ‘ conclusively refuted by unquestionable documentary proof ” ’ ” (People v. Picciotti, 4 N Y 2d 340, 344-345).

We find that no true question of fact exists which would Avarrant a hearing. The facts alleged have been shoAvn to be either demonstrably false or, even if true, not fit grounds for a Avrit of error coram nobis.

The fraud of counsel consists of a charge that defendant’s counsel falsely informed the court that he had advised defendant that a conviction for robbery might carry a minimum sentence of 10 years. This allegation, if conceded, would not justify relief through coram nobis. Although cases may arise where Ave may find that the constitutional rights of a defendant are violated because the representation of retained counsel is inadequate (see Powell v. Alabama, 287 U. S. 45), this is not such a case. The alleged misconduct of counsel chosen by defendant cannot be attributed to “ action on the part of the State ” (see People V. Tomaselli, 7 N Y 2d 350, 354; People v. Brown, 7 N Y 2d 359) and even if proven Avould not constitute a denial of due process.

The denial of the effective aid and assistance of counsel was the result, defendant avers, of counsel’s inability to speak or understand Spanish. As a consequence, he concludes, he did not have the privilege of conferring with counsel. While it is *348certain that a defendant has a full right to be represented by counsel, and the courts may have a duty to assign counsel in specific cases, there is also a corresponding right to insist on a personal counsel (N Y. Const., art. I, § 6). This is a choice which the defendant himself must make, and with which the courts may not interfere (People v. Price, 262 N. Y. 410). In the circumstances presented, such a choice having been consciously made, the defendant may not complain that he was dissatisfied with the representation he received.

The third claim of the defendant deals with the alleged misrepresentations of the official interpreter. The interpreter, defendant asserts, did not translate the questions which the Judge put to counsel and the answers made by counsel in regard to attorney-client conferences and the minimum sentence. There is, however, no requirement that such questions be asked. It is a purely gratuitous act on the part of the court. The question then must be whether this court would vacate the judgment if in fact the interpreter had not translated the colloquy between attorney and court to the defendant. Another way of phrasing this would be whether, if the questions had not been asked at all, would coram nobis lie? We think not. The questions were not required, so that their total absence, above and apart from defendant’s lack of knowledge of such questions and answers, would not be sufficient ground for the vacatur of the judgment.

Finally, all the papers considered by the trial court demonstrate that the presumption of regularity is buttressed with proof. By defendant’s own admission he was represented by counsel of his own choosing and assigned an interpreter, with whom he concededly conversed. The minutes reveal the Judge’s consideration for the defendant’s rights in interrogating both defendant and his lawyer before the plea was taken. The lawyer’s responses when the plea was accepted and his appeal for leniency on the sentence reflected the acts of a knowledgeable, loyal counsel. Where an accused person remains silent, under circumstances where, in spite of an alleged inability to understand English, he was in a position to convey his grievance to the court, he may not thereafter be heard to claim in a collateral attack that the conviction was procured by fraud or misrepresentation (People v. Moore, 284 App. Div. 925).

I dissent because I believe that defendant’s sworn allegations should be tried out in open court, not summarily dismissed without trial. At the age of 20 with no prior criminal record, he pleaded guilty to robbery, first degree, and was sentenced to imprisonment for not less than 10 years and not more than 15 years. He swears in his petition that he did not know that 10 years was the statutory (Penal Law, § 2125) minimum for the crime, that he understood the Spanish language only while his lawyer spoke only English, that he was unable to and did not discuss the case or the matter with his lawyer, and that the court was falsely informed by defendant’s lawyer that the lawyer and defendant had discussed the matter of sentence. There was a Spanish-speaking court interpreter present but, so defendant alleges, the interpreter did not translate to defendant the colloquy between the court and defendant’s lawyer. By reversing an order calling for a trial of such averments, this court holds either that, assuming them to be true, they are no basis for relief, or that they are conclusively shown by undisputable proof to be false. Neither basis is sound.

An absolute minimum of fair play and due process required that proceedings fraught with such consequences should be explained to defendant in a language he could understand by an interpreter, considered for this purpose to be an officer of the court (People v. Randazzio, 194 N. Y. 147). It was the court’s own duty, regardless of what defendant’s counsel did or failed to do, to see that this young and unsophisticated defendant with little or no knowledge of the English tongue knew the meaning and consequences of his plea. This reversal means that whether or not he in fact understood it, nothing can be done about it now since the fault if any was that of his own retained lawyer. That sets much too low a standard of performance and too small a measure of duty for our criminal court judges. I agree with the unanimous Appellate Division that defendant was entitled ‘' through the official services of the court ” to be “ made cognizant of these questions by the Judge ”. That conforms to the holding of People v. Boehm (309 N. Y. 362, 368-369) that a defendant’s inability to understand sentencing procedures is ground for coram nobis relief.

*350The other ground put forth for denying a trial to this defendant— that his allegations are " conclusively refuted by unquestionable documentary proof” (People v. Richetti, 302 N. Y. 290, 296) so that there “ is no reasonable probability at all that defendant’s averments are true” (People v. Guariglia, 303 N. Y. 338, 343) —is entirely inappropriate here. There are not and cannot be any records which ‘' conclusively refute ’ ’ petitioner’s sworn allegations that because of the language difficulty he did not know what was going on. Defendant’s sworn assertions are certainly not “ palpably untrue ” (People v. White, 309 N. Y. 636, 641) and there is no fair way of determining their truth or falsity except by the time-honored and time-tested method of a trial of the fact in open court.

The order appealed from should be affirmed.

Judges Dye, Fuld, Froessel, Van Voorhis and Foster concur with Judge Burke; Chief Judge Desmond dissents in a separate opinion.

Order of the Appellate Division reversed and that of the County Court reinstated.
