… [M]idway through their case, the People introduced a previously undisclosed confession that defendant made to a health care worker at a hospital where he was being treated for a suicide attempt. This statement tended to corroborate a similar confession that defendant made to a detective shortly thereafter. It is undisputed that the People had no statutory duty to disclose this statement, because it was not made to anyone connected with law enforcement (see CPL 240.20[1][a]), and because no Rosario material was involved. Defendant nevertheless complains that his due process right to a fair trial was violated by the timing of the disclosure, because he would have formulated a different defense had he known the People intended to introduce a confession to a civilian witness. However, we find no evidence of deceit or trickery on the part of the People, and defendant’s claim of prejudice is unpersuasive. … [T]here was no misrepresentation that the undisclosed evidence did not exist, and the trial had not progressed to the point where defendant could not have adjusted his defense, or requested less drastic relief than a mistrial.

Defense counsel did not object to the health care worker’s testimony on the ground of physician-patient privilege, and we decline to review this unpreserved claim in the interest of justice. People v Tayo, 2015 NY Slip Op 08353, 1st Dept 11-17-15

“CPL 710.30 could not be clearer” … . When the People intend to offer at trial “testimony regarding an observation of the defendant either at the time or place of the commission of the offense or upon some other occasion relevant to the case, to be given by a witness who has previously identified him as such,” the statute requires the People to notify the defense of such intention within 15 days after arraignment and before trial (CPL 710.30 [1] [b]). Not only is “[t]he statutory mandate . . . plain” but the procedure is “simple” … . The People serve their notice upon defendant, the defendant has an opportunity to move to suppress and the court may hold a Wade hearing (see id.). If the People fail to provide notice, the prosecution may be precluded from introducing such evidence at trial.

The notice statute was “a legislative response to the problem of suggestive and misleading pretrial identification procedures” … . In enacting the notice requirement, the Legislature “attempt[ed] to deal effectively with the reality that not all police-arranged identifications are free from unconstitutional taint” … .

The purpose of the notice requirement is two-fold: it provides the defense with “an opportunity, prior to trial, to investigate the circumstances of the [evidence procured by the state] and prepare the defense accordingly” and “permits an orderly hearing and determination of the issue of the fact . . . thereby preventing the interruption of trial to challenge initially the admission into evidence of the [identification]” … . Thus, the statute contemplates “pretrial resolution of the admissibility of identification testimony where it is alleged that an improper procedure occurred” … . * * *

Detective Vanacore’s surveillance of defendant does not constitute an “observation of . . . defendant . . . so clear that the identification could not be mistaken” thereby obviating the risk of undue suggestiveness … . Therefore, the People were required to serve their notice concerning Detective Vanacore’s observations.

We agree with defendant that the court erred in allowing one of the victims to offer voice identification testimony at trial. Prior to trial, the prosecutor had the victim listen to recordings of telephone calls allegedly made by defendant from jail, and the victim identified the voice of the person making the calls as belonging to defendant. The victim offered similar testimony at trial over defendant’s objection. Because the People failed to provide defendant with notice of the pretrial voice identification procedure as required by CPL 710.30 (1) …, the voice identification testimony was admissible at trial only if the identification was merely confirmatory as a matter of law … . Contrary to the People’s contention, the victim’s identification of defendant’s voice was not merely confirmatory inasmuch as the victim acknowledged that, although he had heard defendant speak a number of times in the neighborhood, he and defendant had never actually spoken to each other. We thus conclude that the People did not establish as a matter of law that the victim was so familiar with defendant’s voice that “the identification at issue could not be the product of undue suggestiveness” … . People v Ramos, 2015 NY Slip OOp 00049, 4th Dept 1-2-15

…[W]e conclude that the court properly refused to preclude the additional statements included in the CPL 710.30 notice served by the People after the superseding indictment was filed … .  “Those [statements] were not referenced in the CPL 710.30 notice that was served in connection with the original indictment, but the record establishes that the People filed the superseding indictment out of necessity after the court dismissed . . . the original indictment” … .  We agree with defendant, however, that the court erred in determining the admissibility of the additional statements without reopening the Huntley hearing and affording defendant a further opportunity to contest their admissibility.  The court concluded that the statements were spontaneously made and therefore not subject to suppression.  At the time of the Huntley hearing conducted in conjunction with the initial indictment, however, the only issue before the court with respect to the additional statements was whether they should be precluded on the ground that they had not been included in the first CPL 710.30 notice.  Consequently, inasmuch as the voluntariness of the additional statements was not at issue at that time, defendant had no reason or opportunity to explore the issues of spontaneity or the effect of the previously-given Miranda warnings, or to raise any other issues regarding the admissibility of those statements.  Thus, “the hearing must be reopened” to afford him that opportunity… . People v Roberts, 945, 4th Dept 10-4-13

Assuming that there was a section 710.30 violation, it might not have resulted in exclusion of the evidence in question. CPL 710.30 (2) provides for the possibility of late notice, and a belated suppression hearing, when the People show “good cause.” The belated notice and hearing may occur during the trial …, and if the trial court thought the People had made an excusable error it might have granted such a remedy here.

In short, it is not obvious that defendant’s counsel could have successfully sought preclusion of the evidence of the victim’s post-arrest identification under section 710.30. An argument for preclusion could have been made, but not an argument “so compelling that a failure to make it amounted to ineffective assistance of counsel” … . Counsel’s performance should not be “second-guessed with the clarity of hindsight” … . Any deficiency in her performance was not so great that it can support an ineffective assistance claim.

Nor has defendant shown any serious likelihood that he was prejudiced by trial counsel’s alleged error. Even if the trial court had precluded evidence of the victim’s post-arrest identification, the evidence against defendant would remain strong. People v Vasquez, 2013 NY Slip Op 01016 [20 NY3d 461], CtApp 2-19-13
