Memorandum.

The order of the Appellate Division should be reversed, without costs, and the [*2]petition dismissed.

After one juror was found unable to serve, defendant refused to substitute an alternate juror and requested a partial verdict{**26 NY3d at 1028} on the one count on which the jury had indicated it had reached a verdict. The Appellate Division granted the petition on the basis that there was no manifest necessity for a mistrial and did not address the issue of consent (120 AD3d 1414 [2014]). Because defendant implicitly consented to a mistrial on two of three counts by requesting a partial verdict and by saying nothing about the court's plans for retrial (People v McFadden, 20 NY3d 260 [2012]; Matter of Marte v Berkman, 16 NY3d 874 [2011]), we need not reach the issue of manifest necessity.

Fahey, J. (concurring). I agree with the majority that the order of the Appellate Division should be reversed, but for a different reason. A defendant's consent to a mistrial, and concomitant waiver of double jeopardy protection, "may . . . be implied from the circumstances leading up to the dismissal of the jury" (People v Ferguson, 67 NY2d 383, 388 [1986]). This Court has held, however, that whether a defendant has "consented to a mistrial is a factual question" (id. at 389; see Matter of Marte v Berkman, 16 NY3d 874, 875 [2011]). As such, that "factual determination . . . may not be disturbed by this Court if there is any support for that finding in the record" (Marte, 16 NY3d at 875).

In this CPLR article 78 proceeding in the nature of prohibition, however, the Appellate Division made no factual finding with respect to whether defendant consented to the mistrial. Rather, the Appellate Division's decision was based solely on that Court's conclusion that "there was no manifest necessity for the declaration of a mistrial" (Matter of Gentil v Margulis, 120 AD3d 1414, 1417 [2d Dept 2014]). Thus, there are no factual findings by a lower court for us to review (cf. Marte, 16 NY3d at 875; Ferguson, 67 NY2d at 389). Furthermore, we have no power to make our own factual determination on this issue (see NY Const, art VI, § 3 [a]; CPLR 5501 [b]).

While the majority relies on the waiver of double jeopardy protection in People v McFadden (20 NY3d 260 [2012]), that case is clearly distinguishable. In McFadden, the defendant affirmatively requested a mistrial (see id. at 262, 264-265). Here, the issue is whether defendant impliedly consented to a mistrial, which presents a factual question (see Marte, 16 NY3d at 875; Ferguson, 67 NY2d at 389).

I would reverse the order of the Appellate Division on the ground that there was manifest necessity for a mistrial on counts two and three of the indictment. As the majority notes, after the trial court determined that one juror was unable to{**26 NY3d at 1029} continue deliberations, defendant refused to consent to the substitution of an alternate juror.

For there to be a "manifest necessity" for a mistrial, such that double jeopardy does not bar retrial, the trial court must consider reasonable alternatives to a mistrial (see Ferguson, 67 NY2d at 388; Matter of Enright v Siedlecki, 59 NY2d 195, 199-200 [1983]). Here, the trial court considered reasonable alternatives to a mistrial, except for the taking of a partial verdict on count one (see Matter of Robles v Bamberger, 219 AD2d 243, 247 [1st Dept 1996], lv denied 88 NY2d 809 [1996], mot to dismiss appeal granted 88 NY2d 962 [1996]; cf. Matter of Rivera v Firetog, 11 NY3d 501, 508 [2008], cert denied 556 US 1193 [2009]). Nevertheless, the trial court's failure to take a partial verdict on count one does not bar retrial on counts two and three.

CPL 310.70 (2) provides that "[f]ollowing the rendition of a partial verdict . . . , a defendant may be retried for any submitted offense upon which the jury was unable to agree," with certain exceptions that are not relevant here. Thus, the trial court's failure to take a partial verdict on count one does not prevent defendant from being retried on counts two and three, inasmuch as the jury was "unable to agree" on counts two and three (CPL 310.70 [2]; see Matter of Dissell v Adams, 115 AD2d 1006, 1008 [4th Dept 1985]).

Defendant's reliance on the Appellate Division's dismissal of the entire indictment in Robles is misplaced. In that case, although the jurors indicated that they had reached a partial verdict, there was no indication as to the count upon which the jury had reached a partial verdict before the trial court declared a mistrial and discharged the jury (see Robles, 219 AD2d at 247-248). There, the Appellate Division properly dismissed the indictment in its entirety (see id. at 248). Here, by contrast, the jury clearly stated that it was deadlocked on counts two and three and, by inference, that it had reached a partial verdict on count one only. Defendant therefore may be retried on counts two and three of the indictment (see CPL 310.70 [2]; Dissell, 115 AD2d at 1008).

Chief Judge Lippman and Judges Pigott, Rivera and Abdus-Salaam concur; Judge Fahey concurs in result in an opinion in which Judge Stein concurs.
