STEPHEN G. CRANE, J.

This case presents an application, novel in New York, of the so-called missing witness inference to a situation where the witness has asserted his Fifth Amendment privilege and rendered himself unavailable. Defendant's request to deliver a missing witness charge in this circumstance is granted.

The People called Barry Allen on their direct case. Mr. Allen was one of the four youths whom defendant allegedly shot on the subway on December 22, 1984. The witness invoked his Fifth Amendment privilege, and the Assistant District Attorney refused to offer immunity to Mr. Allen. This took place outside the presence of the jury, and the jury was never informed that Mr. Allen invoked his privilege. (Cf., People v Thomas, 51 N.Y.2d 466. )

Although invited to do so, the defendant never called Mr. Allen. The Assistant District Attorney at one time indicated to defense counsel that if defendant were to call Mr. Allen he would offer immunity. (See, People v Shapiro, 50 N.Y.2d 747; People v Sapia, 41 N.Y.2d 160, cert denied 434 U.S. 823.) The court tried to make the "cheese more binding" by suggesting that defense counsel could pose leading questions to Mr. Allen and even impeach him on the basis of prior inconsistent statements and his criminal record. (Cf., Chambers v Mississippi, 410 U.S. 284.)

The People had already immunized Troy Canty and James Ramseur who testified before the second Grand Jury that indicted defendant for attempted murder and other serious felonies. (People v Goetz, 68 N.Y.2d 96, 102-103.) It was acknowledged that immunity was being withheld from Barry Allen as trial strategy, and that there was no interest in pressing criminal charges against Mr. Allen stemming from the events of December 22, 1984.

For a party to secure a missing witness charge, there must be an available, uncalled witness in a position to give material evidence that is not simply cumulative and that would naturally be expected to be favorable to the party who has failed to call him. (Richardson, Evidence § 92, at 66 [Prince 10th ed].)

There is no dispute that Barry Allen is in a position to give material evidence that would reasonably be expected to favor the prosecutor. After all, Mr. Allen is a complaining witness against Bernhard Goetz, the man who shot him. This evidence clearly would be noncumulative as demonstrated by Allen's pretrial statements and an interview of him and Troy Canty by the National Enquirer. It would tend to corroborate or contradict one of the contrasting versions of the incident presented by Troy Canty's testimony and defendant's statements in Concord, New Hampshire. (See, People v Rodriguez, 38 N.Y.2d 95, 101; People v Aponte, 69 A.D.2d 204, 219-220.) In addition, Mr. Allen is physically available. He was produced from State prison on the District Attorney's application for a writ of habeas corpus ad testificandum. The District Attorney even called Mr. Allen to the stand on the People's direct case.

It is true that Mr. Allen has been subject to call by the defendant throughout this trial. But, this circumstance in no measure places Mr. Allen within the control of defendant. Where such a witness may be expected to testify favorably to the People, and adversely to defendant, he must be considered in the control of the People, even though defendant had the physical ability to call him. (People v Gonzalez, 68 N.Y.2d 424, 431; cf., People v Wilson, 64 N.Y.2d 634, 636.)

Once the defendant establishes a right to the missing witness charge, the burden shifts to the prosecutor to account for the absence of the witness or to demonstrate that the charge would be inappropriate. (People v Gonzalez, supra, at 428; Chandler v Flynn, 111 A.D.2d 300, 301, appeal dismissed 67 N.Y.2d 647.) In seeking to discharge their burden of showing that the requested charge is inappropriate, the People argue that their failure to elicit testimony from Mr. Allen is excusable because the witness invoked his privilege against self-incrimination and thereby became unavailable to the prosecution. Yet, this contention is but at the threshold of the problem.

A witness who invokes the privilege against self-incrimination is considered unavailable for many purposes. (People v Brown, 26 N.Y.2d 88, 94 [admissions against penal interest]; Richardson, Evidence §§ 258, 260 [Prince 10th ed]; Fed Rules Evid rule 804 [admissibility of former testimony, of statement against interest and of statements of personal or family history].) This factor may allow the prosecutor to escape a missing witness inference, if the People were to furnish a reasonable explanation for withholding immunity from Mr. Allen. (State v Dachtler, 318 N.W.2d 769, 744 [Sup Ct, ND] [dictum].) After all, if the cause for the unavailability of the witness is due to the failure of the People to fulfill a condition (conferral of immunity), the People may not rely on this unavailability (cf., Amies v Wesnofske, 255 N.Y. 156, 162-163). The Assistant District Attorney argues, in effect, that no such explanation can be required of the People because the conferral of immunity is a matter of prosecutorial discretion (CPL 50.30). This discretion is broad. Yet it may be reviewed for abuse. (People v Chin, 67 N.Y.2d 22, 32; People v Adams, 53 N.Y.2d 241, 247; People v Osorio, 86 A.D.2d 233, 239, appeal dismissed 57 N.Y.2d 671.) A frequently cited instance of abuse is presented by a case where the prosecution is built on immunized testimony, yet the defense is denied access to similarly immunized testimony. (See, People v Adams, supra.) By contrast, a prosecutor cannot be criticized for withholding immunity from a coperpetrator, even if he offers to exculpate the defendant. The cases on which the Assistant at bar relies are but examples of this proposition. (See, e.g., Morrison v United States, 365 F.2d 521; United States v Brutzman, 731 F.2d 1449.) Incidentally, these Federal authorities are in accord that the missing witness instruction is a matter for judicial discretion (Morrison v United States, supra, at 524) and that the prosecutor's discretion to withhold immunity is reviewable for abuse (United States v Flomenhoft, 714 F.2d 708, 713).

Contrasting any reasonable grounds for withholding immunity, the case at bar exhibits selectivity among the shooting victims that goes without explanation other than trial strategy. This is insufficient to carry the People's burden of demonstrating that the missing witness charge is inappropriate.

To countenance such a strategy would raise profound constitutional questions of the defendant's right to confront the witnesses against him under the Sixth Amendment of the U.S. Constitution and to his right to due process under the Fourteenth Amendment. (Cf., People v Shapiro, 50 N.Y.2d 747, 760; People v Sapia, 41 N.Y.2d 160, 165, cert denied 434 U.S. 823; see also, United States v Flomenhoft, supra, at 714, and United States v Brutzman, supra, at 1452.) It is basic that a court will not decide constitutional issues unless they are unavoidable. (Matter of Legal Aid Socy. v Scheinman, 73 A.D.2d 411, 413, affd 53 N.Y.2d 12; cf., McKinney's Cons Laws of NY, Book 1, Statutes § 150, at 307, n 62.)

For the foregoing reasons, the jurors will be charged that they may infer, if they wish, that the testimony of Barry Allen would not have been favorable to the People.
