Police “Business Records” and the Unidentified Declarant: Foundation Required Under CPLR 4518 for Hearsay Statements in Investigation Reports

1. Introduction

People v Mawhiney (2026 NY Slip Op 04460 [3d Dept July 16, 2026]) is a Third Department decision addressing when a police preliminary investigation report can be admitted as a business record under CPLR 4518(a) to prove the truth of a hearsay statement—here, that the defendant “was highly intoxicated.”

The case arises from a June 23, 2021 domestic incident that prompted law enforcement to respond to the defendant’s home. Upon arrival, the defendant used a shotgun and fired at a responding state trooper, causing injury. The People charged the defendant by nine-count indictment, and after a retrial he was convicted of, among other offenses, attempted murder in the first degree, attempted murder in the second degree, aggravated assault upon a police officer, and weapons and assault offenses.

The key appellate issue in this appeal was evidentiary: whether County Court erred by excluding a police preliminary investigation report circulated by email that contained a statement that the defendant “was highly intoxicated.” The defense sought admission of that statement to support its theory (expressly not contesting the acts) that intoxication negated the intent element of the charged crimes.

Procedurally, the case had already reached the Third Department once. In People v Mawhiney (220 AD3d 1055 [3d Dept 2023]), the Court reversed and remitted for a new trial, instructing that on remittal the defendant should have an opportunity to lay a proper business-record foundation and noting that if the document qualified under CPLR 4518, the author’s lack of personal knowledge would go to weight rather than admissibility. On remittal, County Court held a hearing and again excluded the report, finding the defense failed to show that the source of the “highly intoxicated” statement was a person with a duty to report. The Third Department affirmed.

2. Summary of the Opinion

The Third Department affirmed the conviction, holding that County Court correctly excluded the preliminary investigation report. The Court rejected the defense argument that County Court “engrafted an additional requirement” into CPLR 4518(a).

The decisive point was foundational: although the report was prepared by a State Police lieutenant in the regular course of police work, the lieutenant did not personally observe the defendant’s intoxication and could not identify who supplied the “highly intoxicated” assertion. Because the defense could not establish that the initial declarant was acting under a business duty to report (or that another hearsay exception applied), the statement could not come in for its truth under the business-record exception.

3. Analysis

3.1. Precedents Cited

Matter of Leon RR. (48 NY2d 117 [1979])

Matter of Leon RR. provides the controlling framework the Court applied. It articulates the “chain” requirement: the proponent must show not only that the entrant had a business duty to record, but also that each participant in the chain —from the initial declarant to the final entrant—was acting within regular business conduct, unless the statement fits another hearsay exception. The Third Department used this principle to focus the inquiry on the unidentified source of the intoxication assertion.

People v Patterson (28 NY3d 544 [2016])

People v Patterson addresses a common business-record scenario: when the entrant has a duty to record but the declarant does not have a duty to impart. In that circumstance, the record may be admitted to prove only that the statement was made; it cannot be admitted for the truth of the statement without an additional hearsay exception.

The Third Department invoked Patterson to explain that even if the lieutenant had a duty to gather and record the information, the defense sought to use the “highly intoxicated” statement for its truth (that the defendant was intoxicated), and the defense identified no separate hearsay exception that would permit that use.

Matter of Country-Wide Ins. Co. v Lobello (186 AD3d 1213 [2d Dept 2020])

Matter of Country-Wide Ins. Co. v Lobello stands for the baseline proposition that hearsay within a police report is not admissible unless an exception applies. The Third Department cited it to situate police reports within ordinary hearsay doctrine: the report’s status as an official police document does not automatically cleanse embedded hearsay.

Gallt v Nelk (240 AD3d 1286 [4th Dept 2025])

Gallt v Nelk is cited alongside Country-Wide to reinforce the same principle in a more recent context: police-report hearsay remains inadmissible absent an applicable exception.

Dawn VV. v State of New York (47 AD3d 1048 [3d Dept 2008])

Dawn VV. v State of New York is a Third Department application of the “chain” and duty-to-report principles in the business-record context. The Court cited it to support the proposition that the business-record exception requires reliability derived from duties throughout the information pipeline, not merely the regularity of the final compilation.

Matter of Messiah S.E. [Micquella E.] (237 AD3d 698 [2d Dept 2025])

Matter of Messiah S.E. [Micquella E.] was cited for consistent application of the business-record foundation requirement—particularly the need for a duty to report within the chain—underscoring that this is settled doctrine across Departments.

Wasilewska v Long Is. Compost Corp. (234 AD3d 802 [2d Dept 2025])

Wasilewska v Long Is. Compost Corp. is cited as another recent statement of CPLR 4518 requirements: the exception is not satisfied where the proponent cannot establish reliability of the underlying hearsay source through a business-duty chain (or some other exception).

People v Morrow (204 AD2d 356 [2d Dept 1994])

People v Morrow is cited to support exclusion where foundational business-record requirements are not met, reflecting longstanding criminal-case application of CPLR 4518 principles to police or investigative documentation.

People v Gannon (174 AD3d 1054 [3d Dept 2019])

The Court cited People v Gannon as general support for excluding hearsay where the proponent cannot fit it within an exception, reinforcing that evidentiary reliability—rather than relevance alone—controls admissibility.

People v Ruff (185 AD2d 454 [3d Dept 1992], affd 81 NY2d 330 [1993]) and People v Morgan (174 AD2d 1034 [4th Dept 1991])

The decision uses People v Ruff (and its affirmance) and People v Morgan for contrast on when police-related records may be admitted and under what foundational circumstances. In this case, the contrast served to underscore that admissibility turns on identifying a qualifying source and satisfying the duty-to-report chain, not on the mere existence of a police record.

People v Sabirov (184 AD3d 714 [2d Dept 2020]) and People v Hunter (244 AD3d 1239 [2d Dept 2025])

The Court cited People v Sabirov and contrasted it with People v Hunter to highlight that sometimes other hearsay exceptions can bridge the gap identified in Patterson. Here, however, the defense did not argue for any alternative exception that would permit the “highly intoxicated” assertion to be used for its truth.

Matter of Emily GG. v India HH. (248 AD3d 1467 [3d Dept 2026])

Matter of Emily GG. v India HH. is cited to support a key factual point: a civilian (such as the defendant’s fiancée) is not under a “business duty” to report to police. The Third Department used it to show that if the statement in the report derived from the fiancée’s 911 description (“drunk as a skunk”), that origin would not satisfy CPLR 4518’s duty-to-report requirement.

People v Mawhiney (220 AD3d 1055 [3d Dept 2023])

The prior appeal, People v Mawhiney (220 AD3d 1055), shaped the remittal posture. The Third Department clarified in the present decision that its earlier “weight not admissibility” language was expressly contingent on first establishing the document’s admissibility as a business record—something the defense failed to do on remittal. This is an important corrective: “weight vs. admissibility” only becomes relevant after the proponent clears foundational gates.

3.2. Legal Reasoning

The Court’s reasoning proceeds in three steps closely tracking CPLR 4518 doctrine.

  1. Police reports are not automatically admissible for hearsay assertions. The Court reiterates that police-report “facts” that are hearsay remain inadmissible unless an exception applies. The business-record exception is a potential route, but it requires a proper foundation.
  2. The business-record foundation requires a reliable chain. Under Matter of Leon RR., it is not enough that a police lieutenant regularly prepares and distributes preliminary reports. The proponent must also show the reliability of the underlying source(s) of key assertions. Specifically:
    • the entrant must have a business duty to record; and
    • the initial declarant must have a business duty to report (or the statement must fit another hearsay exception).
  3. The defense failed on identification and duty-to-report. The lieutenant did not observe the defendant’s intoxication and could not identify the source of the “highly intoxicated” statement. The defense’s suggestion that the statement must have come from an officer because “the scene had been secured” was deemed speculative. The Court also offered a plausible alternative origin (the fiancée’s 911 statement), illustrating why speculation cannot substitute for proof of a business-duty declarant.

Finally, the Court applies People v Patterson: even if a record might show that a statement was made, that does not permit the statement to be used for its truth absent another hearsay exception. Because the defense offered no alternative exception, exclusion was appropriate.

3.3. Impact

The decision’s practical significance is evidentiary and recurring: it clarifies (and enforces) the burden on criminal defendants who seek to introduce police paperwork as exculpatory evidence, especially on intent-negating theories like intoxication.

  • Foundation cannot rest on assumptions about police sources. Where a police report aggregates information “from numerous sources,” the proponent must identify the relevant source or otherwise prove that the relevant statement originated from a person acting under a duty to report (or fits another hearsay exception). “It must have been an officer” is not a foundation.
  • “Weight, not admissibility” is conditional. Trial courts may treat the author’s lack of personal knowledge as a weight issue only after the proponent satisfies the threshold requirements of CPLR 4518. The decision thus helps prevent overreading of appellate “weight” language as an automatic admissibility mandate.
  • Defense use of police records may require alternative hearsay theories. The Court’s reliance on People v Patterson signals that litigants should be prepared to argue not only CPLR 4518, but also an additional exception (where available) if they need embedded statements admitted for their truth (e.g., present sense impression, excited utterance, admission, etc., depending on facts).
  • Likely litigation effect: more granular foundational hearings. Courts may increasingly require hearings that drill down on “who said what to whom” inside police compilations, especially when the proponent seeks to use a particular embedded statement substantively.

4. Complex Concepts Simplified

Hearsay

Hearsay is an out-of-court statement offered to prove the truth of what it says. For example, offering the report’s statement “he was highly intoxicated” to prove the defendant actually was intoxicated is hearsay.

Business Records Exception (CPLR 4518[a])

A record may be admissible if made in the regular course of business, as part of a regular practice, at or near the time of the event. The theory is reliability: routine recordkeeping is thought less likely to be fabricated.

“Chain” Requirement / Duty to Report (Matter of Leon RR.)

If the record repeats information from others, the law asks: did those others also have a work-related duty to give accurate information? If not, the embedded statement remains unreliable hearsay unless some other hearsay exception applies.

“Admissible to show the statement was made” vs. “admissible for its truth” (People v Patterson)

Sometimes a business record can be used only to prove that someone said something (e.g., “a caller reported X”), not that X is actually true. To prove X is true, another hearsay exception is needed.

5. Conclusion

People v Mawhiney reinforces a disciplined approach to CPLR 4518(a) in criminal trials: a police report does not become substantively admissible merely because it is routinely created and circulated. Where a report contains a critical hearsay assertion—such as the defendant being “highly intoxicated”—the proponent must establish a reliable business-duty chain from the initial declarant to the recorder, or else identify a separate hearsay exception permitting the statement’s use for its truth.

The broader significance is methodological: the decision tightens the evidentiary link between reliability and admissibility and cautions litigants against treating “weight, not admissibility” language as a shortcut around foundational requirements.
