Analysis
The governing precedent
People v Ennis and People v Hines
Relying on People v Ennis, 11 NY3d 403, 409-410 (2008), and People v Hines, 228 AD3d 995, 995 (3d Dept 2024), the court began with the basic constitutional rule that criminal defendants are entitled to reasonably competent, conflict-free representation that is “singlemindedly devoted” to their best interests.
This formulation was central because local counsel’s problem was not merely a questionable tactical choice. His decision was influenced by a perceived obligation to preserve the confidence demanded by the judge’s law clerk—an interest distinct from, and incompatible with, complete loyalty to Thayer.
People v Mero
People v Mero, 43 NY3d 407, 416 (2024), supplied the definition of an actual conflict: divided and incompatible loyalties within the same matter that necessarily preclude single-minded advocacy.
The Third Department applied that definition directly. Local counsel testified that he felt “stuck between a rock and a hard place,” torn between the requested secrecy and his duty to the client. That testimony demonstrated an existing conflict affecting counsel’s conduct, not merely a hypothetical risk of future divided loyalty.
People v Wright, People v Solomon, and People v Marshall
People v Wright, 27 NY3d 516, 520-521 (2016), People v Solomon, 20 NY3d 91, 95-96 (2011), and People v Marshall, 173 AD3d 1257, 1259 (3d Dept 2019), establish that, absent a knowing waiver, reversal is required where counsel labors under an actual conflict or a significant possibility of one.
Thayer could not waive the conflict because he did not know the conversation had occurred. The court therefore treated the conflict as constitutionally disqualifying and relied on People v Marshall again in affirming vacatur.
People v Prusinski and People v Hartle
The court contrasted actual conflicts with potential conflicts. Under People v Prusinski, 242 AD3d 1427, 1433 (3d Dept 2025), and People v Hartle, 192 AD3d 1199, 1201 (3d Dept 2021), a potential conflict warrants reversal only when the defendant shows that it operated on the defense.
That more demanding standard did not govern because local counsel’s competing loyalties had already influenced what he withheld from trial counsel and Thayer. In any event, the record showed a concrete effect on the defense’s ability to evaluate the choice between a jury and a bench trial.
People v Prescott
People v Prescott, 21 NY3d 925, 927-928 (2013), supported the conclusion that an unwaived actual conflict depriving a defendant of conflict-free representation requires vacatur. The Third Department cited it in holding that Supreme Court properly set aside the judgment.
People v Black
People v Black, 199 AD3d 824, 825 (2d Dept 2021), supported the separate conclusion that a jury waiver must be knowing, intelligent, and voluntary. Thayer lacked material information concerning the judge he was selecting as factfinder. Consequently, the formal waiver could not establish a constitutionally informed choice.
People v Bradley
In a footnote, the court invoked People v Bradley, 88 NY2d 901, 902-904 (1996), for the principle that a defendant has the right to chart the course of the defense and that a court should not undermine the selected strategy.
This principle was relevant because Thayer had not initially noticed extreme emotional disturbance as a defense. After the People rested, the trial judge raised that theory and suggested amendment of the CPL 250.10 notice. Although Thayer ultimately acquiesced, the sequence reinforced the concern that the court had intruded into the defense’s strategic choices.
People v Segal and People v Israel
People v Segal, 54 NY2d 58, 66 (1981), was cited to explain that the originally noticed defenses—lack of criminal responsibility by reason of mental disease or defect and lack of capacity to form criminal intent—could lead to an acquittal if established.
By contrast, People v Israel, 26 NY3d 236, 239 n (2015), explains that extreme emotional disturbance does not eliminate criminal responsibility. As relevant here, it reduces second-degree murder to first-degree manslaughter. The distinction was consequential: the theory raised by the court produced a manslaughter conviction rather than a complete acquittal.
People v Morris
Relying on CPL 470.15(1) and People v Morris, 176 AD3d 1635, 1636 (4th Dept 2019), the court declined to decide the parties’ double-jeopardy arguments. Because Supreme Court had expressly reserved decision, there was no adverse ruling for the Appellate Division to review. The opinion therefore does not determine which charges may be pursued at the new trial.
Legal reasoning
The decisive point was that the source of the information mattered as much as its substance. A concern about an expert report expressed by local counsel is ordinary strategic advice. The same concern communicated by the intended factfinder’s chambers suggests that the judge may already have formed an unfavorable assessment of the defense evidence.
By concealing that source, local counsel deprived trial counsel and Thayer of the ability to evaluate whether to proceed before a judge or jury, seek recusal, create a record, or take other appropriate action. Local counsel’s partial disclosure therefore did not cure the conflict.
The People argued that local counsel did not personally participate in the formal jury waiver or the bench trial. The court rejected that argument because local counsel knew Thayer intended to waive a jury when he received the information and nevertheless remained silent. Withdrawal at a later point did not undo the earlier failure of loyalty.
Nor did the eventual manslaughter verdict cure the problem. The constitutional injury concerned the integrity of the representation and the validity of the choice of factfinder, not whether the bench trial produced a result less severe than a murder conviction.
Potential impact
-
Defense counsel must prioritize the client over requested secrecy from chambers. A lawyer cannot allow a confidentiality request by court personnel to prevent disclosure of material information needed for the client’s strategic decisions.
-
The provenance of advice may be constitutionally material. Relaying a concern while concealing that it came from the judge’s law clerk may be inadequate where the source changes its significance.
-
Jury waivers require materially informed decision-making. A technically proper waiver may still be invalid if counsel withholds information bearing directly on the neutrality or apparent predisposition of the proposed judicial factfinder.
-
Judicial intervention in defense strategy has limits. Courts should not steer defendants toward unchosen defenses, particularly when doing so may produce a lesser conviction rather than an acquittal.
-
The decision is fact-sensitive. It does not hold that every contact with court staff creates an actual conflict. The critical facts were the private communication, the request for secrecy, the information suggesting the judge’s unfavorable predisposition, and counsel’s resulting nondisclosure.
